Over at Huffington Post, Marc Bekoff, recently wrote an article lambasting Christopher Filardi for collecting a Moustached Kingfisher, a rare bird endemic in the Solomon Islands.
Now, there are two sides to this particular controversy, and I am going to do my darnest NOT to pick one.
Side one: How dare you kill that kingfisher!
The HP article criticized killing a rare bird for collection as the opposite of a conservation effort. It is likened to hunting endangered species, and compassionate conservation. (RadioLab anyone? Don’t mind if I do…)
Side two: You need these kinds of specimen for conservation. And biology.
An excellent public post was written by my friend Josef Uyeda here.
Additionally, Dr. Filardi himself responded justifying his decision, and why specimens are important over at the Audobon society.
Was it right or was it wrong? You decide.
Friend of the blog (and former contributor) Devin Drown is wrapping up his first year on the faculty of the University of Alaska Fairbanks, where he’s been teaching the Principles of Evolution course. As a final assignment, Devin’s students are contributing posts to a class blog, Evolution, Naturally — and the first couple are great!
Margaret Oliver digs into the phylogenetic data used to support the renaming of a genus of desert-adapted, clonally reproducing ferns — after Lady Gaga. It turns out that the singer’s stage name is literally encoded in the DNA sequence that helps differentiate the new genus from its closest relatives, as Oliver illustrates in the best. Phylogeny. Figure. Ever.
Meanwhile, Alexandria Wenninger explains how some species of ants steal larvae from other ant colonies and raise them as workers — and how entomologists are discovering that those kidnapped workers can resist this unasked-for reassignment.
However, there is a growing body of evidence suggesting that the [captured workers] are not always so oblivious to their origins, as researchers observe more and more situations of what they are calling “slave (host) rebellion”. Czechowski and Godzinska, in their recent review article, “Enslaved ants: not as helpless as they were thought to be”, identify four types of rebelling behaviors, which range from aggressive acts by individual ants to a collective uprising against the parasites.
A recent publication (B. Misof, et al. 2014. Phylogenomics resolves the timing and pattern of insect evolution. Science 346 (6210): 763-767.) takes on the herculean task of finding when insects first evolved. This is a particularly vexing question because 1) insects are squishy and don’t fossilize well, and 2) the vast majority of the species on the planet are insects. This is an insect world, we just live in it.
The paper was summarized BRILLIANTLY on WIRED (here). Including my favorite quote:
“Making sense of the diversity of insects in collections has traditionally been a task for a lone expert, usually specializing in just one subset of a group. They become so identified with their study organisms, they may be introduced as “The Ant Man” or “The Wasp Woman.” (No taxonomists I know wear spandex tights and capes to work, for which I am profoundly grateful.)”
Find out about when insects evolved, when they diversified (surprisingly, it started PRIOR to the radiation of angiosperms) and more.
The english countryside is know for gardens filled with magnificent roses and elegant floral arrangements.
But when the Duchess of Northumberland moved into her husbands family castle she decided to do something a little different with her garden… she made it deadly.

Many, many world-class ornithologists have called or do call the Louisiana State University Museum of Natural Science home. This year, LSU grad students Mike Harvey (a NiB! contributor!) and Glenn Seeholzer along with LSU alum Dan Lane and Peruvian ornithologist Fernando Angulo are going to Peru this October to find the most bird species they can in a single 24 hour period and they’re hoping to break the world “Big Day” record. (Which currently stands at a whopping 331 species, set in 1982.) A “Big Day” is a mix of fun and work that takes both passion and planning – this one is no exception. Here’s the Peru Big Day Strategy:
Peru is among the top countries in the world for bird diversity, with roughly 1840 species registered. This makes it a great place to attempt to beat the world big day record. The spectacular Andes Mountain range bisects Peru, and it is so tall that it passes through dramatically different climates between its base and its towering peaks. Each climate band produces it’s own habitat, which in turn has it’s own set of bird species. To the east of the Andes, much of Peru falls within the rainforests of the Amazon Basin, which contain the highest single-site bird diversity in the world. The key to a large list during our big day will be to visit as many habitat bands on the slopes of the Andes as possible, but also to spend enough time in the Amazon lowlands to see some of the many species in that area. In order to do this, we will start at midnight high in the Andes at Abra Patricia, work our way down the eastern slopes of the mountains during the morning, and finish in the afternoon in the Mayo Valley, home to many lowland Amazon bird species.

Last week NPR posted an excellent article about what can only be the coolest pollinator. Ever.
“like a flip-flop that doubles as a beer bottle opener; an optical illusion; a labradoodle; a frenemy, the hummingbird moth falls into that cryptic category of transformers in life that are more than one thing” – Linton Weeks ” What Exactly is that Birdlike Thing?”
Pangolins, or scaly anteaters, are delightfully weird. They have many of the adaptations we associate with anteaters—powerful front claws for breaking into anthills, a narrow snout for nosing into broken-open anthills, long tongues and sticky saliva for slurping up ants*—plus a sleek coat of overlapping scales. And, as you’ll see in this clip from the BBC’s The Life of Mammals, they’re (kind of) bipedal!
Pangolins are so different from other mammals, in fact, that all eight species are in a single genus Manis, which is the only genus in the family Manidae. As of this week the IUCN classifies every species in that family of weird adorable mammals as endangered, critically endangered, or vulnerable to extinction—because, apparently, they’re also pretty tasty.
As a review published in this week’s issue of Science describes in detail, we’re in the middle of the sixth mass extinction (that we know about) since life began on Earth, this one caused by the changes we’ve made to the planet. Pangolins are hardly going to be the only potential victims of that mass extinction—they’d be about 2% of the 322 terrestrial vertebrates estimated to have gone extinct since 1500.
