Habitat - Science topic

"Birdwings mainly inhabit tropical rainforests, particularly primary forests. In the author's experience, however, slightly disturbed, well-illuminated, primary forest (jungle") is preferred over undisturbed, closed (i. e. dimly-illuminated), primary forest. Such environments are mostly those formed during the transition from human disturbed or cultivated ground to climax forest and include narrow trails, open spaces and open forests. Depending on species, some birdwings prefer darker places or better illuminated places but most are known to frequent villages.In recent years, selective logging within tropical forests. (rather than complete felling of all trees) has been adopted. If primary forest is thinned in this way without too much damage to birdwing foodplants, such a site may provide suitable habitat for birdwings. Secondary forest is, therefore, also a habitat of birdwings. Indeed, some species will occupy only secondary forest. However, 'secondary forest in most accounts within this text is used almost synonymously with'primary forest-like environment' (rather than referring to forest formed by successional recovery of vegetation following clear-felling). Birdwing habitats can be loosely divided into emergence sites and nectaring sites. An emergence site is one where larval foodplants grow and where eggs, larvae, and pupae occur. Nectaring sites are those where flowers occur and at which adults feed on nectar."

Looking for some helpful suggestions. I took different positive and negative factors to assess the habitat quality of my study sites. Four of these factors were positive, while four were negative. Each of these factors were assigned a value from 1 to 5 for both negative positive factors (5 reflective of the most desirable score and vice versa). This score was then assigned a weightage which was specific for each factor. E.g. The first positive factor score was multiplied with 4, the second factor score multiplied by 3, the third factor's score by 2, and the fourth positive factor's score by 1. Similar things were done for the negative factors. At the end i added up all positive factors' score (X), and all negative factor scores(Y). However, now when i am supposed to calculate final habitat/site criteria based on these positive and negative factors, i am very much confused, I don't know if i should sum up X and Y, or if should take their difference (X-Y). if i take a difference, a certain site's total score becomes negative. Addition does give me feasible results. But I am not sure if the positive and negative factors should be summed up or subtracted.

Note: I wish to see how different positive and negative factors affect overall habitat quality but Iam afraid summing up will not show the detrimental effect of negative factors o habitat, and on the other hand subtraction keeps resulting in negative values for some sites.

I hope my question is understandable.

Hello!

I am currently situated in Paraguay, where I did research on howler monkeys. I am now in the data analysis fase of my project and pretty stuck.

Background of the project:

I played 5 different sounds (Ship horn, elephant, howling of conspecifics, people talking and a silent control) all once to 9 different monkey groups. The monkey groups were all divided into 3 different habitat types (natural, peri-urban and urban). Within the groups subjects were sampled based on age-sex category (e.g. AM-adult male, JF-juvenile female) and a couple of different reactions were measured, like vocalization, vigilance or movement towards the speaker.

Data collected:

My data was entered in excel with every trial as a row, with columns for the sound, habitat, visibility of the different age-sex categories when doing the trial and a column for every behavior type performed by every age-sex category like picture 1.

I added a column were I divided the behavior performed by a age-sex category, through the amount that age-sex category was visible, creating for example the 'CorTowardsAM' column (cor for corrected).

I then transformed this data to look like picture 2, where ValueMinute is the corrected amount of times a behavior in a particular situation was performed by a particular age-sex category per minute (since the time of sampling was different for a couple of sounds).

Now I do not really know how to analyse this. The main thing I want to know for my research question is if there is a difference in reaction between the habitat types and to a lesser extent between the sound types. Since however, the group compositions vary a lot between groups and also the visibility of subjects varied, I feel like I need to corrert for the differences in groups and age-sex categories.

I am looking now at options of doing multiple different anovas, a linear mixed effects model with habitat and sound as fixed effects and group and subject as random effects. Or maybe I should do an ANCOVA?

Truth is i am a bit lost with my data with so many variables and maybe potential biases.

Picture 3 is a plot from the data to help visualize what I have.

I was hoping if people with more knowledge about how data works could help me a little. Am I on the right track? Is the kind of data I have generally used in a linear mixed effects model? If not, how can I analyse it? If a linear mixed effects model is right, what do I do with the output and do I need to check assumptions beforehand?

Thanks a lot for everyone wanting to look at this long post!

How they adapted to new environments (outside native habitat) from lower elevations to upper or upper to lower elevations

I am curious how should i label species in a certain swamp habitat, since i want to make a difference between the migratory and the "stationary" species. Both of the terms i mentioned in the title seem to leave an impression i am talking about the ability of the species to move in general. Thank you in advance.

What are some trends within environmental sciences and habitat biodiversity? Any ideas are appreciated. Thanks very much.

explain its morphology, taxonomy and habitat distributiion

Hi,

I used Maxent to create a model identifying the best habitats for the Short-eared Owl. I used a 800mX800m grid (0,5 by 0,5 miles). I calculated, for each environmental variable, the percentage of each pixel occupied by that variable. Those were my Environmental layers. My problem is with the response curves: when the value of a single variable is changed and the others are kept to their mean values, my response curves are very flat and all close to 1 (see image "Capure1"). But when each variable is used without the others, the response curves make more sense (see "Capture 2"). Anybody has an explanation?

Thank you very much.

I want to assess the habitat occupancy of a small species in a habitat. What should I collect as field data to assess its habitat occupancy?

Hello I'm currently planning to write my undergraduate thesis about mapping animal habitat suitability using Maxent (I'm planning to use elephant or bear as the topic) and I'm really interested in animal conservation. May I know maybe some literature book, research, guide, or video that can help me to understand more about the Maxent algorithm? Since I'm really new in this field and never learn how to use the application in my major. Thanks!

I'm really curious with how Maxent setting work. I'm using it for elephant habitat mapping. I'm using various variable but I got a problem there. So the first picture is my output, and the second picture the output overlayed by elephants presence. The north (up side of the map) is actually match the data, but the other is actually false since it's city and of course not suitable for elephant. I realized that the problem is because the north side have many elephants presence and the habitat have same characteristic with the middle side so the algorithm count it as a suitable habitat for elephant. Unfortunately the west side that have some elephant points and the south side is actually the one that suitable for habitat, but the algorithm can't read it since the north sample is too dominating. I've tried to delete some of the north sample but it don't make big difference. Please enlighten me about what should I do maybe the Maxent setting or other thing. I'll provide more information about my Maxent setting if it's needed. Thanks!

A survey site of mine is an agricultural plot that for 4 months is used for growing paddy, for the next 4 months it is a meadow and for 4 months it is used for growing vegetables. Can all these be considered different habitats? If yes, please help with the terminology used with these habitats.

I have measured RWC from drier as well as wetter habitats from high elevations (3000-5000m asl) throughout the growing season. I found some species showing low RWC (%), but the Fv/Fm and PhiPS2 are not too low.

Could there be any other reason to show low RWC?

One study says that non-photochemical quenching can also result in low RWC. Maybe?

I will be sampling for larvae of the intertidal insect species that I study, and I am hoping to collect some environmental variables for each sampling site. The larval habitat for my species consists of a matrix of sediment and macroalgae that grows on rocks in the lower intertidal zone (see photos for examples). Since the habitat is exposed during low tides, I would like to know how hot, dry, and saline the larval habitat can get in order to understand what conditions the larvae must withstand. My idea so far was to use a soil moisture probe, soil salinity probe, and a laser thermometer, but maybe there is a better way to get these data. Any advice would be greatly appreciated! Thanks!

Nitrosococcus and Nitrococcus are primarily nitrogen-fixing bacteria species found on saltwater habitats. With regards to this, I am trying to find a suitable and less complex culture medium for isolating these strains. It would also be appreciated if incubation time and temperature will be included in response/s. Thank you!

the hair-like structure look like Bryophytes but not sure. The habitat is the muddy mangrove forest.

Please correct me if I were wrong but a quick look at the Goal No. #14: Life Under Water, of the Sustainable Development Goals suggest that it is primarily focused on conservation of oceanic and coastal ecosystems with special focus on sustainable use of marine fisheries/resources and plastic pollution. Similarly, the Goal No. #15: Life on Land, of the SDGs focuses only on terrestrial ecosystems, with special focus on forests, and does not mention about inland aquatic habitats, wetlands, and freshwater fisheries. In either case, the conservation and sustainable management of inland wetlands, freshwater aquatic habitats, freshwater fisheries/resources went for a toss in the SDGs? Please share your thoughts and correct me if I were wrong. Thank you very much!

Found on the coast of Trefin (North Pembrokeshire, Wales) whilst collecting crab abundance data. Found in a boulder-rich habitat possessing a rich population of Xanthid crabs (both X. hydrophilus and X. pilipes), however none of the hundreds of other individuals found were patterned anything like this. Carapace just under 2 inches in diameter.

Presume it's likely X. pilipes due to the hairy legs but the colouration has thrown me, any opinions much appreciated.

This discussion aims to explore the environmental impacts associated with large dam construction and operation. Large dams have been built worldwide to meet various societal needs, such as hydroelectric power generation, water supply, irrigation, and flood control. However, the ecological consequences of these projects have raised concerns among environmentalists, researchers, and policymakers.

I am interested in gathering thoughts and insights from experts on Researchgate regarding this topic. Specifically, I would like to hear about other aspects related to the environmental impacts of large dams, such as:

Additionally, I would greatly appreciate advice on how to structure and present a comprehensive presentation on this topic. What key points, data, and visuals should be included to effectively communicate the complex interplay between large dams and the environment? Any recommendations or suggestions from fellow experts would be invaluable.

Thank you in advance for your contributions, insights, and guidance on this important topic.

My name is Sean Flynn, and I am currently a Graduate Student at Unity College in Unity, Maine. I am currently in my last two classes and will obtain my Master's Degree in Urban Ecology and Sustainable Planning. The proposed project that I am looking for potential partners for is "GIS in the context of Habitat Suitability with Keystone Species." The project entails using GIS data along with the Habitat Suitability model using various calculations. The time frame is approximately 16 weeks for the project to be fulfilled. Some skills that I can offer are GIS mapping techniques, EPA rules and regulations, and data analysis. I want to speak with you over the phone or in a zoom meeting by Friday of next week to discuss any project possibilities. Thank you for your time and consideration.

Best,

Sean Flynn

Hi all,

I need papers that economically evaluated semi-natural habitats for different ecosystem service (e.g., natural pest control, pollination).

Can anyone please help me out?

Thanks in advance!

This specimen was collected from the intertidal habitat of the Kerala coast, south India.

I am focusing on an Orthoptera species (Anonconotus italoaustriacus), who appears to live in alpine habitat, but different niches in different locations.

Have you other examples among insects?

I would like to compare how different species use their habitat.

Habitat use is measured as the number of times an individual is observed inside the habitat, close to that habitat, or far from it out of 300 observations (so proportions).

If my response variable was just inside/outside (success or failure), I guess I could use beta or logistic regression to test if there are differences between species (is that correct?) and if my data were not constrained between 0 and 1 I could, for example, use multivariate ANOVA, but I don't think this would be correct for proportion data.

Any idea how to analyze this type of data?

(I usually use R for data analysis, so something easily implementable in R would be welcome^^)

Although, mangroves have been acknowledged as effective coastal bio-shields and conservation of the same has been taken up as a collective global agenda[1], a more collaborative and intensive effort should be put in place for conservation of these unique habitats. Similar to the collective efforts at the global level, collective efforts at the local and regional level should be initiated and fostered for conservation and sustainable management of mangrove habitats. In this context a discussion note was prepared to initiate a dialogue with individuals and organizations in India, especially on the eastern Indian coast to initiate the “Eastern Indian Mangrove Alliance for Conservation (EIMAC)”, to collectively identify the issues and opportunities and initiate a collaborative effort for conservation of mangrove habitats, sustainable economic development of the coastal communities and climate change mitigation and adaptation on the eastern Indian coast. The following sections of the discussion note provides an overview of the mangrove habitats of the eastern Indian coast, biodiversity, socio-economic conditions of the artisanal fishermen, and the threats of climate change. It was intended that this discussion note would provide the background and help to open the window for further discussion and initiate collaborative and collective action.

Hey, guys! As we all know, there are many aquatic habitats with high sediment concentration, where microorganisms can be attached not only to particulate organic matter (POM) but also to sediments. Is there any good way to separate them?

I am searching for nice and good quality pictures of the three following boreal plants:

- Pinus sibirica

- Nuphar pumila

- Linnaea borealis

Ideally from Sibiria or Scandinavia.

I would like to use them in a review on boreo-alpine disjunctions.

A good book can be an important teaching aid for undergraduate and postgraduate students as well as a useful reference for professionals at all career stages.

On the topics of wildlife habitat restoration or habitat conservation, which books would you recommend and why?

Looking forward to seeing your suggestions. Links to published book reviews also encouraged.

I am looking for a table where, for each habitat type (EUNIS, Corine land classes) there is an averaged amount of carbon retention per unit area. The region to analyze is Portugal, therefore an European-wide list would fit.

Anyone knows if these data are available?

Thanks in advance.

Normally I carry out research related to terrestrial tardigrades, however I would like to start investigating the fauna of marine tardigrades in Cuba, I have carried out some exploratory samplings at different sites using the classic techniques for the study of meiofauna and those described in the literature on marine tardigrades, however I have not been successful. I have been able to observe other groups of organisms belonging to the marine meiofauna but I have not been able to find tardigrades. Are there any other aspects to take into account in addition to the sampling methodology for the study of marine tardigrades, such as the type of habitat or substrate, wave characteristics, specific areas to sample, etc.?

I would be very appreciative if you introduce a valid guideline for water quality parameters for wildlife habitats.

I have studied seasonal multiscale space use patterns of mammals through camera traps implementing a GLMM framework, and took site as a random factor. I used all GIS-based covariates (except for one i.e. human photo-capture rate as a surrogate for disturbance) in this analysis, and found significant relationships between mammal occurrence and some of the covariates. In this context, I was wondering if I can prepare a habitat suitability map out of it (the best-selected models), it would be really great, but unfortunately, I couldn't find enough literature that can actually guide me.

All comments are welcome and thank you in advance.

I am a master's student looking at conservation grazing using White Park cattle for my project. I am trying to decide how to analyse my GPS data alongside habitat shapefiles to look at which habitat areas are used the most by the cattle. The GPS datapoints are from a Nofence collar which pings approximately every 15 minutes but is not always consistent and some times has extra datapoints. Would integrated step selection analysis using the amt package in r be the best way of analysing this data or is there a more appropriate method? If anyone could give me any tips or guidance on this I would be extremely grateful.

Hi,

As I konw, like stable isotope, amino acid compound-specific isotope analysis, these methods can all used to identify the habitat use and geographic origins and migration of migratory species.

Can you tell me other methods also can be used to do this area. may be otolith of fish.

Hey,

I sampled benthic foraminifera from two sites, in each site from 3 different habitats.

I want to check if the differences in the numbers of species are significant or not.

My data is basically composed of present/ absent numbers and the number of species in each habitat, for example:

Site A:

Habitat 1: 6, 8, 14, 16

Habitat 2: 3, 4, 7, 9

Habitat 3: 4, 6, 9, 10

* There is another table for the other site

* Different numbers within each habitat represent different sampling months.

* From each habitat, at least 3 replicates were sampled. The decision to sum all species present in the replicates is due to the fact that sometimes there is a big variability between the replicates and since the comparison between habitats and sites is more relevant for our question.

Thanks in advance,

Yahel

How can I draw a sample-based rarefaction curve in R?

I have sampled 3 sites using pitfall and light trap methods. I want to draw a sample based rarefaction curve for each site in R, which is the function and syntax that I can use? How do I arrange species and sample data in Excel?

Comparing regressions question: I have arthropod abundance data at different elevations in either forested or open habitats. I want to find the best regression for each elevational pattern (null, linear, exponential, or quadratic) for both habitats, then compare the regressions between habitats. I have to use mixed-models (GLMM) to account for extraneous factors (sample dates & size). What would be the best way to compare regression slopes and graph 95% CI? I'm getting confused on how to compare glmms with different linear, exponential, and quadratic slopes.

Also is this the best approach? Or should I use habitat as a term in the GLMM?

Any help MUCH appreciated!!

Greetings folks,

I'm fiddling with SPSS (I'm a former SYSTAT user and not confident with R yet) to do some basic analyses for some frequency data for turtle habitat detections.

Basically for simplicity sake we tracked radio-tagged box turtles in 4 different habitat types, Flatwoods (FW), Oak Scrub (OS), Grassy Prairie (GP), and Ephemeral Wetlands (EW).

We had the following amount of observed detections FW( 487), OS( 396), GP (67), and EW (68). I figure the most simplistic way to determine if there is a difference in frequency of detections between habitat type is a simple Chi-Square (feel free to suggest other analyses as well if you'd like!).

When I do run a basic Chi-Square I find there is significance (P=0.0001).....however what is the best way to to determine where the significance rises? IE Which groups are significantly different form the other?

I'm familiar with Tukey-Kramer and Bonferonni tests in the context of ANOVA, and Kruskal-Wallace in Non-parametric analyses... but not sure the best steps to see where the significance lies between these 4 groups in a Chi-Square context.

Any help is greatly appreciated, but especially in the context of SPSS. I've seen some sources on Post-hoc analyses in that program, but most of those deal with additional other grouping variables (IE sex or season) in Chi-square which I will move onto next!

Thoughts and all help/explanations are welcome!

Looking for journal article study on how covid 19 impacted the wildlife habitat affecting ecological, social, Environmental and political dimensions

At the sampling site in different habitats at various forest type like alpine grassland, tropical, subtropical forest. Being a beginner researcher, what should be intial scientific approaches to consider before collection of data in study site interm of highlighted key points such as pre and post sampling options, frames, techniques, heterogeneity, with respect to the way of consistently accuracy of research...

I am looking for opportunities to expand my research. Please let me know if you have any information.

Just a note, I am available for collaboration on papers and projects.

Hi all, I'm wondering if anyone knows of a way to calculate the area (of a polygon, particular habitat, etc) while excluding a piece of the polygon in QGIS. More specifically, I am trying to calculate the area of forested habitat surrounding alpine zones, so I'd like to exclude the alpine habitat from my measurements. I am a bit rusty with QGIS currently!

The caracal, Caracal caracal (Schreber, 1776), is one among the medium-sized carnivore distributed in arid and semiarid tracts of western part of the country. The rapid pace of habitat destruction and ongoing anthropogenic activities in the natural areas of this animal causes severe impact on the population and distribution of caracal. The arid and semi-arid tracts of Gujarat are one of the important natural habitats of this animal where its present status is unknown. It is reflected by the world status of this animal which is data deficient as per IUCN Redlist of threatened animal and a schedule I species under Indian Wildlife (Protection) Act, 1972. In Gujarat, this animal is less understood about its population and distribution.

I am currently creating a species distribution model with Maxent in R. The problem I am facing is that the habitat suitability prediction is always different. When I run the model twice, with the same configuration, two different maps will result. That is because I use random background points (there is no sample bias in my data, so no need for that) and these are of course always randomly sampled.

So how should I treat that. Should I create ten maps and average the habitat suitability value? Or should I evaluate the model each time and choose the one with the highest evaluation metric score?

If someone has literature on that would be good as well.

Hello everyone,

I would like to know if there is a package from R, Python, or something like that to classify plant species according to their use (food, construction, medicinal, ...), habitat, native climate, life cycle, whether it is crop or wild and vegetation type.

I have been doing this manually using the "Plants of the World Online" and "Encyclopedia of Life" websites, but I am afraid of making mistakes, particularly for native climate.

Could someone please suggest something?

Thank you very much for your attention.

I have checked some collections (http://catalogue-cfbp.inra.fr/recherche.php http://www.wi.knaw.nl/collections/ https://www.dsmz.de/) but most of the strains were isolated a long time ago and the information of the isolation habitat is not complete. If someone is working on this pathogen and could share some strains would be really kind. Thank you.

My study revolves around the cuvier's gazelle ( Gazella cuvieri ) in its natural habitat.

How can I get the most of my days in the field, and come back with as much information as I can.

A precise protocol would be appreciated, the study focus is population dynamics and overall population behavior.

Our need to create alternative water sources is increasing day by day. However, while providing alternative water resources, can we adequately predict long-term effects on the natural balance? Although the dams built on rivers and streams are useful as an irrigation and energy source, serious damage occurs to the habitat on the natural passage areas of the streams. Similarly, can rainwater harvesting in urban or rural areas (especially covering large areas) cause adverse effects both in terms of feeding aquifers and soil-water balance? I don't have a clear opinion on this subject, but I think that we should question how we affect nature in the long run and that we should take our steps carefully.

A little outside my usual field or work and a little outside their usual habitat, but my limited kmowledge makes me think they are monogeneans(?)

thank-you in advance

The rising sea levels and mangroves are salt-tolerant trees that line tropical and subtropical coastlines. How does the reforestation of mangroves contribute to regulating the global climate through carbon sequestration and storage? Coastal protection from storms? Reduced flood risk? Habitat for distinct species?

I assumed that the hybridization of two langur species in Bhutan is happening due to habitat modification and land use change. I wanted to determine how land use change has contributed towards habitat modification.

Thanks

Our university project group is studying the possibility to apply a plan for the (local) restoration of ice based habitats of polar bears (Ursus maritimus). Has the idea already been developed in some way?

I have foud that it is quite difficult to collect spiders from dense grasslands, both using the "beating" method or the vacumm.

We aim to capture nocturnal flying insects (which can be potential prey for bats) and, therefore, we are going to use UV light traps.

We will sample three different habitats in Colombia: preserved savannas, riparian forest, and rice crops. Our idea is to sample the open area (savanna, rice fields) at the same time as the forest, and we are contemplating installing two light traps in each one of these habitats, with a separation of c. 100 m.

Is it appropriate to use two traps per habitat to get a good idea of insect diversity?

Kindly suggest some unique notes on variability in behaviour and the habitat utilization which is observable in Macaca assamensis (primates) of Eastern Himalayas in tropical forest of northeast India. Thanks a ton for suggestion.

I have camera traps data which was deployed at several sites (islands). The data consist of only N (abundance; independent image) of each species at their respected islands. No occupancy modelling could be run as I do not have the habitat data. Is it possible to calculate the occupancy and probability without the temporal data/repeated sampling (the week the species was detected)? Or would calculating the Naive Occupancy would do? Furthermore, does Occupancy and Probability has a range of high and low?

I am doing a GLMM analysis using R, where I have 2 predictor variables (fixed effects) which do not interact, each one has few levels. My factors are “Habitat” and “Year”.

I am interested in doing a post-hoc multiple pairwise comparison between the 4 levels of “Habitat”, to see which ones are significantly different, within every year.

When I use contrast(habitat.dif, alpha=0.05, method="pairwise", adjust="Tukey"), I get a comparison between the averages of the groups across all years and not within every year.

My model is:

abundance.model1<-glmer.nb(Abundance~Habitat+Year+ (1|round)+(1|Block), data=table1)

habitat.dif<-lsmeans(abundance.model, pairwise~Habitat|Year)

contrast(habitat.dif, alpha=0.05, method="pairwise", adjust="Tukey")

I don’t understand what am I doing wrong. I will appreciate your help

I am working on a paper Assessing the effectivity of biotic indices in elucidating the health of freshwater habitats in peatland ecosystem. Here, I am assessing the performance of the ff indices: BMWP, BMWPThai, BMWPViet, ASPT, ASPTThai, ASPTViet & SingScore. However, I am not so sure if it would be okay to test the effectivity of these indices considering that we did not take samples on physico-chemical parameters due to budget constraint. We only collected the macroinvertebrates. In addition, the area does not have a pristine condition. We sampled only sites which are less to heavily disturbed. I would be glad if you can share your expertise on this study. Thank you.

Is the cloglog output produced from Maxent a probability of occurrence or habitat suitability? I know this is a pretty fundamental question about Maxent. I have read all of the typically cited papers and there is no concensus about this. Any clarification would be appreciated.

In the microbial ecology there are two words used to describe the microbial environment

Habitat and Nich

What are the differences between them

Hello…

Any suggestions regarding identification of the following benthic foraminifera elphidium(?) species (attached) and their habitats/environments?
