Questions related to Coastal Ecology
I am searching for a database presenting the STATUS of Extinction (Red list for example) about COASTAL INVERTEBRATE SPECIES!
What are the basic elements for a good management of the coastal ecosystem? how about the experiences of countries? articles or any links?
Greetings and Good day to all,
I am working through a project and was seeking information from anyone that has had experience using the South Florida Water Management DBHYDRO data platform.
Also if anyone has any information on comparison or analysis of salinities between wet_dry season and then how to graphically show the influence on natural salinity fluctuation/changes and then pinpoint where Freshwater inflow effect those level due to artificial actions like opening_closing levees.
My Gratitude and Thanks
I am not understanding very well the dynamic of benthic exchange in coastal sites and if is a process that normally can occurrs fast (hours to days) or slowly (weeks to decades)?
I need this information to understand the variability of concentration in long-lived and short lived Radium isotopes in a coastal aquifer
Studies from Indian coastal and estuarine waters show that heterotrophic dinoflagellates are negatively correlated with oxygen/ dominant in hypoxic water.
Wenlu Lana., Bangqin Huang., Minhan Dai., Xiuren Ning., Lingfeng Huang., Huasheng Hong. (2009). Dynamics of hetrotrophic dinoflagellates of the Pearl River Estuary. Northern South China Sea. Estuarine, Coastal and Shelf Science 85, 422–430.
Please answer this question.
The zooplankton density estimated in this study ranged from 354-771 cells per ml. That means it is 354000-771000 cells per liter. If you see the available literature from Indian coasts as well as from the same Kalpakkam coast, zooplankton density generally will be in the range of 200000-600000 cells per 10000 liters of seawater. Even many authors have reported similar densities for 100000 liters of seawater. So its unimaginable how such huge numbers were arrived.
Generally, a phytoplankton bloom with 700000 cells per liter density can be seen in naked eye as a distinct layer of green, brown or red colour on sea surface. So, with this high density of zooplankton reported in this paper, the sea will be full of zooplankton. With this density, if you take one liter of seawater, 20-30 % of the volume will be occupied by zooplankton considering the presence of gelatinous species encountered by the authors in this study. Practically, it is just impossible.
I would love to collaborate, as I am trying to record their global occurrence. As for now, there are no records from South American coasts and few from eastern Asia and Australia. But with only 100 species known worldwide there should be plenty more.
I need the district and village wise shape file of Kerala for plotting vulnerability of coastal villages.Can any one provide me with .shp/.smz files for further analysis in spss.
I am currently analysing temporal and spatial zooplankton groups and in many samples from the same time period there appears to be a very high proportion (~90%) of the same group (Cladocera). I have been unable to find literature related to whether zooplankton (specifically cladocera) can develop in blooms under optimum conditions, similar to those of phytoplankton.
If anyone could point me in the direction of any literature related to this topic, it would be greatly appreciated!
As we all know that more and more marine habitats are degenerating because of anthropogenic activities in the ocean and other reseaons, for example, fishing, climate changes. So we need to do something to change the situation.
Can you guys give me some restoration mehods or suggestions, especially for the coastal area.
I am doing a GIS project on different coastal ecosystems and need a representation of such ecosystems. Corals, Mangroves and Seagrass I have, but kelp is missing...Thank you!
While I can find good references for dynamics related to substrate size - community or species on sandy beaches, I would like to find more about potential effects of substrate color (which is finally due to its composition).
Even at temperate latitudes, darker color means higher temperatures under the same radiation. Is there any reported effect of this on life-history traits, or some kind of experiment to test differences in behaviour/physiology of resident species?
I will be increasing T by 2C every few days and need a heater that can do this accurately for a few gallons of seawater
I am trying to use the generalized modes on WAMIT to simulate free surface movement, but when I try to modify the newmodes.dll file WAMIT doesn't working, sending the message: "Error 0007: Error loading import library.newmodes.dll".
I have been trying to modify the dll using Intel Visual Fortran, as recommended in the manual, but it's a more recent version of it. Now I am not sure if I am using the correct procedure, so if anyone could help me with this, maybe with a tutorial or anything, I would be really glad.
Thanks for the help in advance.
I need literature to made a report on integrated coastal management applied to the western Southamerica littoral, mainly Peru. Many places of the work are within the Humboldtian biogeographical region according to Sullivan and Bustamante. But, I have not many experience to build the process to made a plan for ICZM in this zone.
Can you possibly help me to identify the following images?
These were collected from the Chilika lake ecosystem dated 12.12.2008. But proper identification was not made till now.
can anybody help me on this aspect and also can you provide the available literature on this species?
Is anyone working on modeling how changes to coral reefs may change coastal erosion models. This is something I am very interested in getting into and is wondering if anyone would be interested in collaborating or has suggestions on who to speak to. Thanks!
I'm currently working on IUCN Red List assessments for syngnathid fishes. Many are Australian endemics, some of which inhabit seagrass beds. Dedicated surveys and population estimates are few and far between for these species, so it helps with assessments if we know the status of their habitat.
Collected from the coastal waters (benthic domain) of the Bay of Bengal, please help me identify the specimens. Anyone? Guess these are teatae amoeba!
The emerging concept of Anthropocene, era in which human influences modify various environmental properties, has direct implications on coastal research. Indeed, anthropogenic chemical (e.g. metals, pesticides, pharmaceuticals), physical (e.g. microplastics, sediments, temperature) and biological (e.g. invasive species, eutrophication) stressors increasingly affect marine and coastal aquatic systems. Thus, what is the meaning of pollution if the understanding of coastal environments is intrinsically linked to the identification of shifts on contaminant baselines, biology, and oceanographic variables. I will be chairing a session at YOUMARES 7 (link below), and welcome abstracts (deadline June 15) discussing coastal and marine pollution in a broad context including environmental changes related to human interference.
Also contribution and responses posted here might be presented during the session opening.
We are working on a project looking at the relationship between CDOM and DOC across a large gradient of ecosystems. With 10 000+ observations we are still looking for more data.
Anyone aware of possible open data repository?
For clarity, in the spirit of advancing science through open access to publications and data, authorship does not follow from the inclusion of published data. For further information, see guidelines from e.g. EU (https://ec.europa.eu/research/openscience/) and NSF (http://www.nsf.gov/bfa/dias/policy/dmp.jsp).
I am currently modelling the potential distribution of the invasive Caprella mutica and native species of Caprellidae (for starters C. linearis) in the North Sea. From my own work I have obtained several offshore samples in the Dutch part of the North Sea. Furthermore I have received data from colleagues in other countries, but the total dataset is still very small. From literature I have obtained hundreds of presence-only observations (e.g. from Cook et al., 2007). But I found hardly any presence-absence data of Caprellidae.
Is there anyone that has this type of data from the North Sea and is interested in sharing this? Thank you for reading my question!
Here are some pictures of the same species taken from different esacals
This species is typical of red mangrove roots submerged from Cispata Bay
There are many ecosystem services in the wetlands, such as habitat protection, material circulation. Does anyone have good suggestions for measuring such services?
Can anybody help me to identify this specimen ( Probably Armina maculata ??) collected from Coastal waters of Bay of Bengal?
I was reading the paper "Integrated biomarker response: a useful tool for ecological risk assessement", by Beliaeff et al 2002, and I was trying out the computations as in the example (Computation of IBR at station W3 (Warnemunde Estuary) in March 1995, p1318) and there's one thing I couldn't quite follow.
When the authors write about the minimum value (Min) for all stations and/or surveys for each biomarker, I would think the minimum value (that later on we add to Z to calculate the score S) would be obtained directly from the original dataset (not shown in the article), but what I don't understand is how the Min values are below zero for biomarker levels. I mean, measured enzyme activities are always above zero.
Therefore my questions are: i) how is it we obtain the Min value? or iii) are the minimum values relative values, such as a fold-change in enzyme activity?
In addition, when we have to place a + or - sign in Z (showing upregulation or downregulation in biomarker levels), does that correspond to what is expected in theory or to what was actually observed in the data?
Thanks a lot.
I am currently carrying out a research on climate compatible development through mangrove restoration in Coral Coast Fiji. Unfortunately, there has not been any studies carried out on carbon sequestration rate in this region. However, the Mangroves for Fiji, estimate the carbon sequestration rate as 1 metric ton per hectare per year. I was wondering can I use this figure to calculate the carbon sequestration rate of the replanted mangroves in this region or is there any other method which I can utilise.
If I want to evaluate nutrient enrichment in different areas, such as coastal areas and estuaries, should the evaluation criteria be the same or not? And in the case of different evaluation criteria, how can I compare the different evaluation results to the same extent?
I've heard a speaker refer to it in a talk. It reviews percentage of species with indirect\direct\empirical evidence of any negative impacts (namely on biodiversity). I believe it was published in 2014 or 2013. I'm almost positive that it reviewed marine species, but can not recall if it included terrestrial species as well. Obviously, I do not recall the names of authors nor journal.
Any assistance would be much appreciated,
I'm currently writing a paper concerning the collection and identification of interstitial meiofauna communities along different stations on a tourist beach in the Philippines. I'll be collecting and preserving surface sediment samples using PVC corers then isolating meiofauna using a series of sieves. Afterwards, I'll identify the meiofauna up to the family level. I need a good way to calculate and compare the biodiversity indices of the communities along the different sections of the beach.
If you don't mind, could you take a look at these photos (attached) and tell me what you think may have caused the condition in these crabs? They show some curious black lesions on Metacarcinus magister (formerly Cancer magister) we caught during a biological survey about 10 nmi off the mouth of the Columbia River last summer. They were caught in a dredged material disposal site in a few hundred feet of water over silty-sand substrate. Could they be from chitinoclastic bacterial infection or something else?
I appreciate any insight that can be offered. Thanks!
To examine if human activity since 1950s have enhanced the coastal surface productivity I would like to measure some proxies. TOC (%) and BSi (%) are both influenced by preservation and dilution effect from non-organic input. Pigment is used in some cases but difficult to analyze? 13C and 15N?
I am working in a mangrove in Bermuda where Ucides is not reported. Goniopsis is always present on the trees but I do see a crab disappearing into burrows and assumed it was Goniopsis. Your most recent paper indicated that Goniopsis is not a burrower. So I need to determine who this borrower is!
Thanks for a response when you have the time.
Hi, I am looking for information on work being done that examines carbon dynamics in seagrass / eelgrass and salt marsh ecosystems in Canada. I am undertaking some work to determine carbon accumulation rates on the Pacific coast and am interested to see if other work has been done in the region and in Canada.
I'm doing research on Molluscs, using a specific specie named Patella Cochlear. Ecological importance and sexual reproduction of patella cochlear.
Can I have information or links on ecology and biological study of the polychaete species of the Algerian coast, and I would like to have some literature on invasive species and endemic to the Mediterranean Sea. Grazie
I need information or interesting links on the ecology and biology of polychaetes of the Mediterranean Sea (except FAUVEL, 1923 and 1927, Fauchald, 1977). Thanks
Integrated Coastal Management (ICM) is considered as a governance process by Olsen, Lowry and Tobey (1999) and by Olsen and Nickerson (2003). However I realize and support the criterion that “Integrated Coastal Zone Management” (ICZM) is limited to a management process, not specifically a governance one. Governance addresses the values, policies, laws and institutions by which a set of issues are addressed (Olsen, 2003).
I am correlating pCO2 with fluorescence in the Western basin of the Mediterranean Sea. This basin is oligotrophic, but in the spring blooms can occur. I was expecting during this season the pCO2 to decrease due to the biological activity, but the correlation coefficient is positive. What could be the cause behind that?
As distinct from State/local council policy & guidelines & theoretical modelling for climate change and coastal recession,I am interested in looking at adaptive or barrier based models specific to identified "at risk" locations on the Western Victorian Coastline. Sandy beach front communities in particular with minimal land area for urban expansion.
Is it suitable to conduct a mangrove propagule dispersal simulation using MIKE 21 advection/simulation module?
Can anyone suggest what other module in this software is also suitable for this simulation with tidal and salinity as its input field data?
I'm particularly interested in the relationship between quantity and quality in fresh and saltwater wetlands, and riparian buffers in tidally influenced waters with respect to ecosystem services.
For example, is 1000 acres of poorly functioning salt marsh equal to 500 acres of good quality salt marsh with respect to water purification or maintenance of fishes?
