grrlscientist | August 24, 2009The cricket sang,
And set the sun,
And workmen finished, one by one,
Their seam the day upon.
The low grass loaded with the dew,
The twilight stood as strangers do
With hat in hand, polite and new,
To stay as if, or go.
A vastness, as a neighbor, came,--
A wisdom without face or name,
A peace, as hemispheres at home,--
And so the night became.

This is the cutest event I've heard of for NYC: a night spent counting crickets and katydids.

In this video, we are given a look at a pod of Orcas -- "killer whales" -- Orcinus orca, that live in the Antarctic. I have spent many happy hours in Friday Harbor at the University of Washington's research station, watching Orcas and talking to the biologists who study them. These biologists were fairly certain that the Friday harbor Orcas are a different subspecies or species from those orcas that live in more open waters, such as the ones you see in this video. The reasons? At the time, they didn't have DNA…

laelaps | June 13, 2009This past January I had the pleasure to re-visit Duke University's lemur center in North Carolina. I really recommend that you stop by if you have the chance (I'm hoping to head back to North Carolina sometime this summer myself), but if NC is beyond your reach the center has posted a number of videos of the non-anthropoid primates in residence. Among my favorites are the aye-ayes (Daubentonia madagascariensis), which you can see in the videos below;

Because I do not own a television, I was thrilled to find that Lord of the Ants, the Nova program that aired on PBS tonight, is freely available as a streaming video. This program describes some of EO Wilson's amazing discoveries about ant communication, behavioral ecology and evolution [52:23]

razib | May 18, 2009Ed Yong has an excellent review of new research which casts substantial doubt on the trivia chestnut that Komodo dragons kill their prey with their extremely pathogen rich saliva. The more prosaic answer seems to be that they utilize poison, not particularly surprising or trivia worthy for a reptile. But the truth is not always sexy.
laelaps | April 12, 2009Ah, Easter. The holiday when many people ask "Wait, bunnies don't lay eggs. What gives?" Not everyone is a fan of the Easter Bunny, though. In Australia rabbits are a major pest and some have attempted to raise awareness of a local, endangered marsupial called the bilby by offering it as an alternative Easter mascot.
A greater bilby (Macrotis lagotis).Personally, I think another Australian mammal is a better fit as an Easter mascot. The platypus (Ornithorhynchus anatinus) is a monotreme, or one of the few mammals in the world that lays eggs. I would much prefer an Easter platypus to an…

Common Eastern Bumblebee, Bombus impatiens.
This species is often relied upon to pollinate commercial food crops,
such as tomatoes, that are often grown in agricultural greenhouses.
Image: Wikipedia [larger view].
The Bumblebees, Bombus species, are among the most popular of all insects. Their black-and-yellow fuzz, large round bodies, and bumbling, buzzing flight make them appear almost cuddly, almost like the "teddy bears" of insects. I have many childhood memories of watching these appealing gentle…

A large brilliant green tree frog, Nyctimystes species, with enormous eyes, was discovered by scientists next to a clear-running mountain river.

A brilliant green tree tree frog with giant black eyes, tentatively classified as a Nyctimystes species, is one of 56 new species of animals discovered during a 2008 expedition to the remote island of Papua New Guinea.
This species of frog is specially adapted to its habitat of rushing freshwater rivers: females lay their eggs underneath…

The Cuckoo Catfish, Synodontis multipunctatus [Siluriformes: Mochokidae].
This is the only fish that is a known brood parasite.
This is one of the species included in this newly-published study.

One of the groups of fishes that I worked with as an aquarist for nearly my entire life are the synodontids, often known as "squeaker catfish" for their ability to make high-pitched sounds. These…

Gouldian finches, Erythrura gouldiae, are small cavity-nesting passerines that are endemic to open savannahs adjacent to mangrove swamps in northern Australia. These finches eat a variety of native grass seeds, but to meet the increased energetic and nutritional demands of rearing chicks, they primarily eat insects when breeding…

An ocean without its unnamed monsters would be like a completely dreamless sleep.
-- John Steinbeck, The Log from the Sea of Cortez (Penguin Classics; 1995).
Unlike any of the kids I grew up with, I was absolutely fascinated by sharks. Despite their bloodthirsty reputation, I saw them as elegant and beautiful creatures, although I never appreciated them as individual personalities. But when you read journalist Susan Casey's book, The Devil's…

A rare pink Bottlenose dolphin, Tursiops truncatus, has resurfaced two years after it had first been seen in Lake Calcasieu, an inland saltwater estuary, north of the Gulf of Mexico in southwestern Louisiana.
The young dolphin, which was first sighted as a calf in June 2007 and photographed a few weeks later, gets its brilliant pink color and bright red eyes from blood vessels that lie just below its layer of blubber. This pink color is…

I don't quite know what to make of Richard Fortey's latest book Dry Storeroom No. 1: The Secret life of the Natural History Museum. When I opened my copy to the first chapter I was expecting something like Douglas Preston's written tour of the American Museum of Natural History, Dinosaurs in the Attic, but Fortey's book turned out to be something entirely different.
I enjoyed Preston's book because it used a motley collection of artifacts, both on display and behind closed doors, to tell stories about the AMNH and the people who worked there. It was not comprehensive or even representative,…

I love art, birds and travel, and because Africa has such a huge variety of exotic wildlife that I've only ever seen in zoos and aviaries, it is high on my list of places to visit. Recently, David G. Derrick, Jr., the author of a new book that combines art and African wildlife into an unusual diary format, asked if I would like to read and review his new book, African Diaries: Sketches & Observations (self-published, 2008).
This slim paperback is an unusual travel…
