New paper!
Molecules in lake sediments provide new information about past herbivores in Yellowstone
Molecular signatures of dung vary among wild herbivores. Fecal steroids in lake mud show that bison/elk were dominant herbivores for over 2k yr in a small catchment.

Analyzing fecal steroids in lake sediments opens exciting possibilities for understanding past wildlife and their ecological impacts. Such records can provide valuable information about the role of wild herbivores in grazed ecosystems.

Woolly mammoths survived on Wrangel Island until 2000 BC!
But why did they go extinct?
Were they doomed once stuck on the island?
We went to Siberia, collected bones & teeth, and sequenced 21 complete genomes.
Here is what we found (🧵)

Check out our recent work!
Buuveibaatar et al. present the 1st near-range-wide population estimate of Mongolian gazelles, estimating a total population size of c. 2.14 million in Mongolia alone, making this nomadic species one of the most numerous open-plains ungulates globally 🦌 doi.org/mr5k

Mule deer are in long term decline and we don't know why. Joel Ruprecht mined the literature to find 722 estimates across 8 vital rates. Using these vital rates and their correlation structure, he ran a life stage simulation analysis to see which most explain population growth /1

Familiar storm clouds off the craggy outlines of Portmuck on the County Antrim Coast. Less familiar is the appearance of icebergs and woolly mammoth! Thought, by some, to have once roamed the area.

New Paper! 🚨 Pleased to have this paper out from my Masters work. We incorporated Pleistocene fossil records of saiga antelope, alongside modern and historic data, into contemporary SDMs to better understand the species environment relationship.
