One of the most fundamental questions in all of science, drawing the interest of laypersons and scientists alike, concerns the number of animals that inhabit the Earth. Game wardens often count deer and ducks, marine biologists tally fish and amateurs may count birds visiting a feeder, but is ...
The reasons given are spiralling costs, uncertainty in supply lines and the economic reality that offshore wind farms are hideously expensive to operate as well as being enormously damaging to the marine environment. Has The Dutch Farmers’ Party’s Moment ArrivedQuite recently, back...
However, trained biologists can tell similar species apart. We have carefully reviewed the available taxonomic information and conclude that the Bicknell's thrush (Catharus bicknelli) is a valid taxonomic species. The Bicknell's thrush breeds during the summer (May to August) in ar...

When you're a firefly, finding "the one" can change the world. Literally. A new study by UCSB evolutionary biologists Todd Oakley and Emily Ellis demonstrates that for fireflies, octopuses and other animals that choose mates via bioluminescent courtship, sexual selection increases the number of sp...
