How Whales And Other Marine Mammals React To Sonar

NOAA’s Fisheries Service, in partnership with top international scientists and the U.S. Navy, has just completed a pioneering research effort in Hawaii to measure the biology and behavior of some of the most poorly understood whales on Earth. During the study, for the first time, scientists attached listening and movement sensors on marine mammals around realistic military operations.

New Mode Of Gene Regulation Discovered In Mammals

Researchers at the University of California, Santa Cruz, have discovered a type of gene regulation never before observed in mammals -- a "ribozyme" that controls the activity of an important family of genes in several different species.

Big Predatory Mammals Such As Felines Need Between 5 And 7 Different Types Of Prey To Meet Their Dietary Needs

Faced with earlier studies stating that the big predators such as tigers, lions, and lynxes fulfil their dietary needs by eating one or two types of prey, scientists from the University of Malaga assure us now that felines need from 5 to 7 different types of prey to fulfil their dietary needs, although they may be more specialised anatomically than the canines (wolves, dogs) who can obtain 100% ingested biomass by eating three types of prey.

High-Altitude Small Mammals Of The Great Basin Are Not Completely Isolated

The term "sky islands" sounds intriguing, but it may be more lyrical than useful when discussing mammal distributions, according to new research from Eric Waltari of the Sackler Institute of Comparative Genomics at the American Museum of Natural History and Robert Guralnick from the University of Colorado at Boulder.

Feather Fossils Could Yield Dinosaur Colors (LiveScience.com)

Artists may now be able to paint dinosaurs and ancient birds and mammals in their true colors, thanks to the discovery of pigment residues in fossilized feathers.

Over 100 Species Of Bats Found Within Several Acres Of Rainforest In Ecuador

Bats are a remarkable evolutionary success story representing the second largest group of mammals, outnumbered only by rodents in number of species. Now, researchers of the Leibniz-Institute for Zoo and Wildlife Research in Berlin (Germany) and Boston University (U.S.A.) have discovered the place that harbours the highest number of bat species ever recorded. In a few ha* of rainforest in the Amazon basin of eastern Ecuador, the authors have found more than 100 species of bats.

Scientists isolate ovulation gene

By the day, the month, or by the year (if you're a bear), all female mammals ovulate. Yet the release of the mighty egg, crucial to conception and survival of species, has been a biological mystery.

Red tide threatens marine animals

Scientists say they believe a huge swath of red algae in the St. Lawrence River is killing marine mammals, including the threatened beluga whale.

AUDIO: Marine biologists interpret whale sounds

The splashes, barks and grunts of baleen whales carry much more meaning than biologists thought, according to the latest survey of the marine mammals.
