Animals - Science topic
Animals are unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
Questions related to Animals
Hi everyone, I am looking for animal data sets that can be compared to the plant datasets from Smithsonian plots. The Smithsonian tree plots census plants in a local community (a plot) above a size threshold; size is measured by stem DBH, and plants are identified to species. I am looking for animal datasets that are similar; that is, they need to contain most of the individuals in a given community (say, mammals or insects or fish) ID'd to species or morphospecies; and they need to have all of the masses of the individuals (not just averages for the species). So far I have found some good small mammal trapping data sets from LTER in the USA, and some tree canopy fumigation datasets for insects. What kind of data are available for large mammals, insects, spiders, molluscs, fish, birds, reptiles, amphibians, etc.? I am looking for datasets of any size, location, and timescale. Thanks so much.
so I'm currently writing on my Ph.D. thesis and have problems finding a basis for the discussion of my data. So here's the thing:
My project dealt with the regulation of a certain DNA repair pathway during development.
For my assays, I used fibroblasts that were isolated from embryonic or postnatal mice (E13.5 or P21) in which one specific kinase (A) important for this repair pathway was knocked out.
In postnatal fibroblasts, I could confirm previous findings of our lab that kinase A is essential for this DNA repair pathway.
However, when I repeated these assays using MEFs, the depletion of kinase A was not resulting in a repair defect anymore. I confirmed this in WT fibroblasts transiently depleted for kinase A using siRNA and also in animal experiments.
So finally, I was able to find that another kinase (B) of the same family is replacing the function of kinase A and phosphorylates the same substrate in MEFs, although kinase A is still expressed.
Unfortunately, I struggle to find literature that provides information about similar processes, meaning a switch in kinases within one pathway in response to differentiation/developmental processes. Is something like this already known?
Thanks for your help!
Do we need to understand zoonotic diseases better to avoid more pandemics in future? Should we all turn vegetarians? Is eating animals the only issue or there are some other human-animal interactions which need to be understood? Will vising the zoos be safe? Or even keeping pet animals?
Please have a logical discussion around these and ask related questions.
Dear all taxonomists
Do you think that the problem which we had with Zootaxa in this year is an accidental or we should expect similar problems in the future? Not only for Zootaxa but also with other taxonomic journals. Do you think that we can do something with it? Any strategy or ideas? Do we have this problem only in zoology or also in botany?
I am working on assessment of water footprint of dairy animals. But I am stuck in calculation of indirect water footprint consumed by dairy animals.
An owl bursting through a cloud of bubbles is helping researchers better understand the aerodynamics of flight.
Birds gliding through bubbles reveal aerodynamic trick. Gliding birds use tail to generate extra lift and reduce drag. For more details please refer to the following link:
The approach to human innovation, via emulating nature, is called biomimetic design and has inspired many of our greatest creations – from buildings to bionic cars, here are some of the favourite examples.
We would like to start marking animals in our animal facility. We can invest a small amount of money in tattoo equipment.
Is it possible to buy a cheap tattoo gun (kit) and which one would be suitable?
Is there a specific needle that needs to be used for laboratory rats and mice?
Which kind of pigment do you recommend?
I am wondering if there is any simple way to isolate intact (medium or high quality) total RNA from selected zoo animals. What is the best material for this? Fresh saliva, droppings, hair or something other? I am interested in some tumor supressor gene, which is probably low expressed.
My laboratory workflow:
sampling material -> conservation in RNALater -> RNA isolation -> reverse transcription into cDNA -> PCR -> sequencing PCR amplicon
Invasive sampling of whole blood or tissue is not possible due to many formalities and legislative obstruction.
Has anybody experiences with it? What is the best material and method for animal non-invasive intact RNA isolation?
Thank you very much for answers :-)
I am interested in studying the role of anthropomorphism in human and animal companion attachment. I want to also understand the phenomenon of abandonment of pets, and if there is a relationship with anthropomorphism and attachment with the same.
I am looking for an inventory where all known species of plants and animals in the Socotra archipelago are registered.
Thanks in advantage.
In recent days an article was published in the Washington Post trying to sell the idea that we, humans, should not work towards preventing the extinction of as many endangered species as possible, and that we should only focus on saving species that might help us survived as species as longer as possible. This is the article:
Our colleague Dr. Alexandre Antonelli is organizing a rebuttal and everyone is welcome to sign it. It is currently aimed as a short commentary in the Washington Post, but I believe it might be possible that this would lead to a larger perspective piece in a scientific journals. Please take a look at the short 750-words manuscript and feel free to sign if you agree with the text. To do so, please use the following link and open the corresponding documents: https://drive.google.com/drive/folders/1VJuKuXDP62NQcBdIuIkCi-LqMyRbORv2?usp=sharing
I'm wondering what would be a more suitable software for motion analysis
in terms of animal monitoring, camels to be exact,
How can one get the speed, distance, acceleration, and maybe incorporate those with vital organs indicators like heartbeats, body temperature ..etc.
trying to build a database for camels linking the above information and looking for patterns.
tried Kinovea but its not quite accurate in my opinion, for a beginner level.
I have once made an observation that a spider apparently resided on a wall that had almost the same colour as the spider him-/herself. I lived at this location for several months and could see the spider almost daily.
I am certainly not an expert on spiders, nor am I an expert on animal cognition. I tried to question why the spider apparently chose this location. Since houses are painted repeatedly, evolution seemed an impossible explanation (this would imply survival of the fittest, because the spider was best adapted to the environment, where several generations of the spider subsequently resided there). This house was the only house in this area that was painted in this colour.
Rather, it seemed that the spider deliberately chose this location, because the spider recognized his/her own look and therefore knew that he/she is least likely spotted on this wall, which gave him/her an advantage to catch prey and to remain unseen by predators. This, however, would require remarkable cognitive abilities. I would be grateful for an opinion of an expert or for stimulating discussion among lay people like myself. See below for a picture of the spider.
Many thanks and best wishes,
The sweep technique (The hunter choses a trail which he will use. Leaves and sticks are removed from the soil – a cleaning or sweep of the trail. The purpose of this is to avoid the production of any sounds which could alert the target species while the hunter walking along the trail. The trail is perpendicularly to paths used by the animals, locally denominated "carreiro" or near to feeding sites areas. Once the animal’s approach is detected, the hunter goes to the location where the animal will most likely be visible or waiting and attempt to kill the animal.) is common between indingenous and non-indigenous in Brazil.
I am interested in attempting to increase activity progressively over time throughout the aging process. I expect it is physiologically possible to increase activity but have not been able to identify any animal or human study in the published literature.
I am writing my MSc thesis about vocal communication in woolly monkeys and I want to make a general description of their different types of calls. I want to obtain various acoustic parameters such as duration, frequency range, low frequency, high frequency, maximum amplitude, average frequency, initial frequency, and final frequency. Hence, I have to analyse my recordings using SoundRuler, but I've never used this software before. I've read the instructions but I have some questions anyway.
- I recorded in stereo, so when I introduce the recording in the software, it asks me if I want to analyse left or right channel. Can I analyse both separately and then calculate the mean of both channels?
- Also, when I introduce the recording, I mark the section that I want to analyse using green bars. Once this section is marked, I proceed to do the analysis. Is it as easy as clicking the "manual" button? When I do it, it appears a table with the different values of the parameters, but I don't know if it is as "simple" as that.
That's all at the moment. Thank you for your answers!
We measured average blood glucose levels in male Wistar rats as follows:
Age matched control animals - 124 mg/dL (non-fasting) and 83 mg/dL (fasting)
High-caloric diet fed animals - 139 mg/dL (non-fasting) and 105 mg/dL (fasting)
How will these values be classified?
I can't seem to find any published guidelines for classifying animals as normoglycemic or hyperglycemic.
I'm specifically looking for fasting and non-fasting guidelines.
I am interested in understanding ways to classify species which are of increased risk of becoming invasive species. Can we come up with a list of comparative attributes that will help authorities adjust policy regarding the movement of exotic animals using scientific logic?
In part of my research i have to develop the abundance biomass curves for the gastropods.In most of the cases i found dead animals (only the shells of gastropods).Therefore i want to know an exact method of measuring the biomass of them using the muffle furnace. At which temperature for how many hours?
I am interested in doing a subchronic drug paradigm and would like to look at protein levels. How long after the last drug treatment is given should I sacrifice the animals and look at protein levels?
We administered Triton at a dose of 200mg/kg to experimental rats at a dose of 200mg/kg i.p. and after 10 minutes of injection the animals started showing writhing responses, suffocation and finally died.
Can anyone help me find out the reason for this and how to combat this problem?
I am recording video of birds foraging in different tree species in order to get accurate data about different behaviours etc. Does anyone know if there is a good way to watch the videos to get accurate times etc, or if there is a computer program that would be good to use? I'm thinking something along the lines of Raven Pro (for sound recordings), but for video. Thanks!
I am interested in finding an exercise wheel of an appropriate size for monkeys or dogs. Does anyone know of a commercially available wheel? It needs to have the ability to give data about speed and time spent on the wheel.
We pool samples from 3-5 animals and is stat analysis done differently comparing to testing samples from each separate animal?
We have attempted to do this and are recently now aware of such interpretation relating to the Altai. Are there others? I thought it possible in the American Southwest rock art and saw reference to a discussion there as well. Any other areas? How did you make this connection? On what have you based your arguments?
Species that normally migrate but can not because they are in captivity or injured, unrecoverable animals. How do they get around this innate behavior.
I am working with C57BL6 mice, which are little aggressive.
I need to feed them by oral gavage. We have tried doing it in wake animals but they are giving us a tough time holding them and even if we manage to do that, the animal is wriggling so much that we ended up injuring one mice while performing the gavage.
So I want to know whether it can be considered to anesthetize the mice and then perform the gavage?
Any references or videos demonstrating the same would be helpful.
It is known that the ingestion of some plants high in selenocistathionine can cause seleno toxicity. I would like to know if the endogenous synthesis and, under specific conditions, accumulation of this metabolite can possibly be toxic or cause any impairment in the metabolism. Thank you
We have problems on our Bongo, Tragelaphus eurycerus, in which some individuals seem slender even we serve them sufficient leaves and pallets. If there Bongo keepers offer me the daily diet list of this animal? It will be helpful to compare the detailed contents for the nutrition issue on our Bongo. Many thanks.
I'm looking for so-called hard evidence about the impact of urban pressure on animals. I need concrete examples. I want to block the construction of a large hotel complex on the border of the National Park. There is only general information in the literature that urban pressure has a negative impact on nature. No examples which would be evidence. Can anyone help?
I want to ask you about the period of time that is taken to change the animal body condition score after application of some management techniques
In general, MCA was found in some animals from different latitude, however, I am not sure whether MCA hypothesis also suit for animals from the different altitude.
Hello everyone, I am looking for some recent articles which is related on using animal and plant proteins and their effects on egg production and quality? thanks in advance
How to calculate/quantify water use efficiency of meat production in indoor concentrated feed based feeding system?
I'd prefer a book using results based on both molecular and classical methods. If there's no such book covering the whole animal phylogeny, then I'd also welcome a book on "Chordata" or "Vertebrata".
The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, and carnivorous mammal. They are often called a housecat when kept as an indoor pet, or simply a cat when there is no need to distinguish them from other felids and felines. Cats are often valued by humans for companionship, and their ability to hunt vermin and household pests.
A small group of cats have some difficulties to drink water. How can you improve them to drink more water?
I wanted to know if anyone is an expert in the area of genotoxicity and reproductive toxicity and has the animal lab facility that we can collaborate.
I get higher creatinine serum levels in the treated groups receiving the androgenic compound compared to the control and untreated ones, is there is any explanation for this? Thanks you all
Does anyone know if there are any articles written on the impact of cold or warm fronts on the gestation period of farmed animals and where I could find them if there are any? Thank you for any directions.
can anyone help me in installing a differential pressure gauge in animal house (preclinical) and tell me the range of pressure to be maintained.
I thought the opinion article written by Pieter Roelfsema and Stefan Treue did a great job of explaining the complex issues involved in NHP research, as well as some of the research breakthroughs that have come as a result of NHP research, with positive consequences for brain understanding and human health. The article ends by encouraging researchers to engage in more public outreach to ensure continuing support. But the question of how this could be accomplished is not addressed.
I asked similar question some time ago and i want to try to get the help once more! During experiments with abdominal writhing induced with acetic acid very different results are obtained! In the same group (control with vehicle) large discrepancy in number of writhing is observed? Also different publications are saying that in 20 minutes the animal has like 100 wriths! That is unbelievable for me! I have never seen more that c.a. 45 wriths during 20 minutes!
I want information about counting the number of birds and wild animals that die as a result of accidents on the roads.
