Meanwhile, human beings have also been working to counteract the effects of their development and growth as well as man-made climate change. Measures like the U.S. Endangered Species Act, habitat-protecting nature reserves and hunting prohibitions are all designed to slow the rate of extinction and preserve dwindling species. But a new paper in the journal Biological Conservation says we may not be trying hard enough. A team of Australian researchers led by environmental scientist Lochran Traill finds that current conservation policy tends to underestimate the number of individuals needed in a population of endangered species to keep...
...okay, though – “it’s a public school.” Her solution for the entire club: Vitamin D! Pseudoephedrine. Suddenly the kids are on top of school and enthusiastic about their extracurriculars. Finn even wants to build a house with Habitat for Humanity. Omg, hooray: it’s like Harvard...

...this because they've studied not only Ardi's fossils but also 110 other remnants they uncovered, which belonged to at least 35 Ar. ramidus individuals. Combine those bones with the thousands of plant and animal fossils from the site and they get a remarkably clear picture of the habitat Ardi roamed some 200,000 generations ago. It was a grassy woodland with patches of denser forest and freshwater springs. Colobus monkeys chattered in the trees, while baboons, elephants, spiral-horned antelopes and hyenas roamed the terrain. Shrews, hares, porcupines and small carnivores scuttled in the underbrush. There were...
...mammal experts. They say firing airguns in certain waters and at certain times of the year can be extremely harmful to a long list of sea creatures, including dolphins, whales, porpoises, giant squids, crabs and sea turtles. The noise the guns generate causes some animals to flee their native habitat, says Naomi Rose, senior scientist with the Maryland office of Humane Society International (HSI). "Their use can cause stress to some animals as well - and you should never underestimate the harm that stress can cause." (See 10 species facing extinction...
