Is Krill the New Palm Oil?

For Earth Day 2016, I wrote about how growth of palm oil plantations has removed habitat for many tropical species, and that plantations are expanding globally as demand for cheap oil increases.  But if demand for these cheap oils does not decrease, what other sources are available?  Some consider krill oil a potential replacement or…

Rewilding: restoring lost species to save ecosystems

At first they were just shadows, dark impressions glimpsed through the mist. Is that really…? Could it be…? As we moved a little closer one of them turned to the east, to face the rising sun. His profile was unmistakable, the curved horns and humped shoulders proclaiming “bison”! And not just any bison, but free-ranging European bison, grazing…

Hunting as a Driver of Selection in Red Deer Male red deer (Cervus elaphus elaphus)who survived hunting season were found to have strong fine-scale habitat shifts to areas with more cover (less horizontal line sight). By tracking deer that were ultimately either hunted or survived hunting season, Lone et al. were able to see exactly…

Species Delimitation for Endangered Species An important way in which evolution and conservation intersect occurs by identifying species relationships for closely related species, particularly if some members of the group may be threatened or endangered with extinction. By lumping “good” species together, census size will be larger and species may be overlooked to receive local…

New Research by SNPits Blogger Anna on Detecting Rare Species from Predator Scat! DNA testing to detect rare species from non-invasive samples (e.g. faeces) is becoming more and more common in wildlife management. If DNA results are used to inform management decisions, then it is important to understand the risks and consequences of false positive…

ESA Recovery Wood storks have been down-listed from endangered to threatened. Always inspirational to see long term conservation actions make a difference! Trophic cascade amongst carnivores Wolves linked to fewer coyotes, but more red foxes. Politically Correct Phylogenetics This paper reviews the history of PC-ness in phylogenetics then argues why we should keep calling things…

Sick elephants E. coli spread across savanna elephant social groups. Habitat and host traits are more important factors than sociality. Trophic cascades Deer seem to use human-associated habitat to seek refuge from coyotes, causing trophic cascade effects on wildflowers. (Sub) Community function New article describes soil fungal variation across North America and finds that while…
