Dear colleagues
I am looking for recommendations for assessment of diet selectivity of a fish-eating bird.
I have data on relative numbers and weight, as well as sizes, of prey species estimated from bird diet samples. I also have results from gill-net monitoring fisheries (length, weight and number of fish) from the same area.
For a beginner in this field (i.e. me), what would be a straightforward way to start looking at the diet selectivity of the birds?
Are there indices that look at selectivity of both species size distribution?
Kind regards,
Karl

Answer
Having been a fish farmer (Rainbow Trout), my recommended diet for fish-eating birds is buckshot.

Hi all,
In order to analyze the distribution of seabirds, I need to get information on the zooplankton in several localities throughout the Atlantic. Does this exists, as raster layers (or equivalent)?
I already explored the copepod tool (https://www.st.nmfs.noaa.gov/copepod/toolkit/) without success.
Thanks in advance,
Fernando

I m wandering if the attenuation of visible light in lakes could be used as an indicator for the predation risk for zooplankton, while they do the diet vertical migration. 
I have searched on google scholar, not found any information on this subject, however, most articles have the basic data of fish biomass and light attenuation coefficient (Kd). 
I suppose if there is no direct link between those 2 factors of DVM. It might be good to do an meta-analysis for this kind of study. 
I just want to know is anyone have maybe study on the same topic?

Hi Anton, thanks so much for references, I will look into those papers
Just few drop of look, I see something very interesting in those articles.

I'm especially interested in species for which telemetry is not possible. Grey literature must record recoveries, but I haven't found any review.
Thank you!

Answer
There is currently no review that covers all seabird species across countries in the north-east Atlantic (i.e. north-west Europe). Most countries have published national ringing atlases, that's probably the best way to get an overview. Iceland is a notable exception. EURING is currently planning a joint atlas of ringing recoveries throughout Europe, but I guess it will be a few years before this is out.

I am looking for data on flight speeds of gulls, terns, skuas, gannets and divers (loons) in the northern hemisphere, or GPS, radar and other data from which flight speeds could be calculated. The project needs to work out the flight speeds for 17 species of seabird and how the speed differs depending on behaviour i.e. migratory flight, flight between nesting and feeding sites, and flying while at feeding grounds.

seabirds.net and particularly Atlas of Seabirds at Sea may be helpful. Other links on the page as well.  http://www.seabirds.net/seabirdinfonetwork.html

I am interested in studying the mutualistic relationship between phytoplankton and seabirds, and how it plays a key factor in sensing climate change in a marine ecosystem (the specific mechanism/s). I also want to determine how ecological imbalances can affect climate change regulation.

Good Morning
Thank you for your attention to my work. I recommend you to use a principal component analysis (PCA) housed in free software XLSTAT. This is free software for a test a month once installed on your computer. It’s a form of excel very advanced.

We have data on seabird mortality, injuries and oiling as a result of falling into small pelagic purse-seine fishing nets. We need to evaluate impact of oiling and injuries to the populations, as well as rates of mortality as a result of these injuries and oiling. We have not found any information concerning mortality rates of oiled and injured birds and no information on effects of fish oil on survival capacity birds that have been oiled during this type of fishing operations. Is this oiling different from that of birds being exposed to fish processing plants, which has been studied, and what are the differences?
