Hey everyone, here’s something I bet you didn’t think you’d see this week: a weasel riding on the back of a flying woodpecker! No, they’re not engaging in The Neverending Story cosplay. This incredible image, taken in Hornchurch Country Park in East London, captures the weasel in the middle of...

Younger JL, Clucas GV, Kooyman G, Wienecke B, Rogers AD, Trathan PN, Hart T, Miller KJ 2015 Too much of a good thing: sea ice extent may have forced emperor penguins into refugia during the last glacial maximum. Glob Change Biol doi:10.1111/gcb.12882
http://onlinelibrary.wiley.com/doi/10.1111/gcb.12882/abstract

The relationship between population structure and demographic history is critical to understanding microevolutionand for predicting the resilience of species to environmental change. Using mitochondrial DNA from extant coloniesand radiocarbon-dated subfossils, we present the first microevolutionary analysis of emperor penguins (Aptenodytes forsteri) and show their population trends throughout the last glacial maximum (LGM, 19.5–16 kya) and during thesubsequent period of warming and sea ice retreat. We found evidence for three mitochondrial clades within emperorpenguins, suggesting that they were isolated within three glacial refugia during the LGM. One of these clades hasremained largely isolated within the Ross Sea, while the two other clades have intermixed around the coast of Antarc-tica from Adelie Land to the Weddell Sea. The differentiation of the Ross Sea population has been preserved despiterapid population growth and opportunities for migration. Low effective population sizes during the LGM, followedby a rapid expansion around the beginning of the Holocene, suggest that an optimum set of sea ice conditions existfor emperor penguins, corresponding to available foraging area.

"a major cause of this lack of repeatability is not being considered: the wide sample-to-sample variability in the P value. We explain why P is fickle to discourage the ill-informed practice of interpreting analyses based predominantly on this statistic."

Evolution is a fact
If you're tired of arguing with people who don't understand evolution, here's the ammunition you need.

Perhaps what these sorts of points—or even more, an in-depth look at how important evolution is to medicine and agriculture—can do is sway the apathetic, who see evolution vs. creationism as a debate between science and religion that doesn't concern them. There are a lot of these people in the U.S., and some of them are in public office.

August 2014: "The Atlantic Forest (Mata Atlântica) is one of the most important and threatened biodiversity hotspots in the world, containing the only living examples of nearly 10,000 species of plant and more bird species than all of Europe... Situated along the Atlantic coast of Brazil, it once covered an area of nearly 1.5 million square kilometres. Today, the forest... covers only 160,000 km2, because of deforestation. "

Brazil could conserve its valuable Atlantic Forest by investing just 0.01 per cent of its annual GDP, according to a new study.

Competing bluebirds make tougher sons
"Female western bluebirds that have to compete for nesting sites produce more early-hatching male chicks than do females with fewer competitors. The chicks are also likely to be more aggressive."

General Behavior  - 
 
Scientists taught new foraging techniques to great tits (Parus major) and tracked them. From only two trained birds per sub-population, the information spread via social network to reach about 75% of individuals. Interestingly, individuals favoured social information over personal information!

Introduction
Interested in birds, conservation, and science communication! I study habitat fragmentation impacts on extinction, factoring in animal movement.

"In the end we will conserve only what we love. We will love only what we understand. We will understand only what we are taught."
 - Baba Dioum

"I once had a sparrow alight upon my shoulder for a moment... and I felt that I was more distinguished by that circumstance than I should have been by any epaulet I could have worn."
 - Henry David Thoreau

"Living wild species are like a library of books still unread. Our heedless destruction of them is akin to burning the library without ever having read its books."
