Bulk tissue versus amino acid carbon stable isotopes to reveal the diet and basal resource use of an invasive rodent Stable isotope analysis (SIA) is widely used to reconstruct food webs, characterize trophic relationships, and estimate dietary composition. However, bulk tissue SIA (BSIA) can yield imprecise estima...

New paper out! A methods-focused paper comparing bulk tissue stable isotope analysis with carbon stable isotope analysis of amino acids to reconstruct diet and resource use!

Stream the Beautiful Highs and Violent Lows of Albatross Life With This New 24-Hour Camera on Midway Atoll You can see the large white seabirds dancing, preening, feeding and raising young—though the live feed might show a dark side of island living, too, with potential predation from invasive mice

Midway Atoll has a new cam that allows you to see intimate moments in the lives of Laysan albatrosses. I wrote an article for @smithsonianmag.bsky.social about what to watch for... @friendsofmidway.bsky.social, @explorerwieteke.bsky.social www.smithsonianmag.com/science-natu...

Just reposting this which I think is the most gorgeous thing I have seen in my career - a critically endangered orange-bellied parrot feeding on a carpet of daisies after an ecological burn. This was the first time they’d had the chance to feed naturally in 15y and was wonderful to witness
