I can think of two instances where very common species suffered severe rapid declines to the extent that they could be considered threatened with extinction - the Chytrid fungus and some species of frogs, and Geomyces destructans and three species of bats; can anyone think of other examples?

My research team and I are in the market for lightweight, remote-downloadable GPS collars to use on bobcats and ocelots.
The collars need to be around 180g and we would prefer collars with a UHF remote download function. The two manufacturers I am considering right now are Lotek and Telemetry Solutions.
If anyone has experience using these, or other GPS collars, I would love to hear your feedback. Specifically, I am interested in finding out the rate of premature failures for these collars and in determining how difficult it is to download data in the field via the UHF receiver.

Question:
Is there any study about the necessary amount of plastic or rubber markers to label food provided to deer and about their effect on food selection?
We investigate the consumption of winter supplementary food by red deer. We would need some citations to support our method.

[more]
Does anybody know where to find good growth curves (length vs age/ time and weight vs age/ time) for loggerhead turtles? Most valuable are datasets over a longer timespan, for turtles of a known age, and preferably also length-weight combinations, so something zoos or research/rehabilitation stations would have.
I found some papers (ie Parker 1929) but most of the data are incomplete, or have just weight not length (in this instance), or have growth curves of length vs time, but the actual age of turtles is not known. I also found some growth curves for hatchlings, but they are reared only to age of 10 weeks (which is valuable but just is a minor part of their lifespan)
I tried contacting some zoos, and have been doing that for the last couple of months, but still no success. Any publication containing that data would be awesome, or if you know someone willing to share/collaborate on this type of data, I would appreciate their contact.

[more]
For an spatial analysis on passerines and other bird species (with modellistic purposes) we need information about the estimated home-range for several European birds species (into the families Sylvidae, Picidae, Emberizidae, etc.). The obvious useful tool could be the Cramp (paperbook or electronic format). Another very nice and useful thing is the BTO web, with bird facts section (http://www.bto.org/about-birds/birdfacts). But I have not found there the request information for all species.
Do you know other tools where these informations can be obtained in an easy and facilitated way?

I am curious how snow and or temperature affect the timing of initial arrival and subsequent dispersal of spring staging waterfowl in the sub arctic. Especially for species such as Canada geese, American black ducks, common goldeneye, and greater scaup, when they are near their final breeding grounds but are waiting for the landscape to thaw.

The paper by Tan et al. (2013), "Into the night: camera traps reveal nocturnal activity
in a presumptive diurnal primate, Rhinopithecus brelichi" (see attached), describing nocturnal activity in R. brelichi would apparently add them to the list of primate species with cathemeral activity patterns. Could cathemerality be characteristic of species in the genus Rhinopithecus that occur at higher altitudes and, thus, are subject to greater seasonal stresses (i.e, thermal stress and reduced food availability in the winter)?

Im doing genetic mapping studies, to compare conservation of genome arrangement across the animal kingdom. I need suggestions for animals that can be easily (relatively) cultured in the lab. Critera include: must be able to reproduce with just one set of parents; number of offspring at least 12 (50-100 would be ideal). We have already done this (or had collaborations) with things such as brine shrimp, sea urchins, hydra, and earthworms. Alternatively, they could be caught in the wild (as a brood or egg pouch). Please let me know if you have any suggestions, or have some animals in culture that youd be willing to collaborate with us on. For our part, we will do some high throughput sequencing, get a draft genome you can use, and do the genetic mapping. So far we have about a dozen animals we have been able to do this for, but wed like to expand our database by as much as possible. the bottleneck is the data analysis. There is not a lot of good genetic mapping data out there for the wide range of animals wed like to compare, so we are trying to establish that data ourselves. Weve got a good high throughput and data analysis pipeline to take advantage of, we just need to get our hands on more animals. Under represented phyla would be great. Also, those animals whose genetic map has already been constructed would be redundant, such as Drosophila, although having some reference genome for an organism would always be helpful, but we are prepared to work with non-model organisms.
Thanks, look forward to receiving input and possibly collaborating.

If I understand correctly light field cameras collect all light in the field of view and all sections of the image can be focused on after the fact. I think this could have amazing applications for wildlife observation work. The model I have seen on the Internet don't seem to have any ability to be programmed to take pictures on a schedule, at night etc. I am curious if anyone has tried to use one of these devics in a wildlife setting and if so what types of success (or problems drawbacks) they have encountered.
