 | A study by the University of Exeter has highlighted the problems of reintroducing animals to the wild for conservation projects. Published online in the journal Biological Conservation, the research highlights the low survival rates of captive carnivores that are released into their natural habitats. On average only one in three captive-born carnivores survives in the wild, with most deaths related to human activities. ...> Full Article |

 | According to Darwin's theory of evolution, individuals in a species pass successful traits onto their offspring through a process called "deterministic inheritance." Over multiple generations, advantageous developmental trends - such as the lengthening of the giraffe's neck - occur. ...> Full Article |
 | Low-temperature stress is a chief environment factor that hinders plant growth, development as well as its geographic distribution and yield. Cell membrane is the major part of a plant where the harm takes place and the molecular changes in the membrane and membrane lipid are one of the initial signals in plant adaptation to and survival after freezing. ...> Full Article |
 | Monkeys living on an island without big cat predators do not show any particular alarm when recorded tiger growls are played to them, according to research by a UC Davis graduate student. The pig-tailed langurs do, however, flee in a hurry from the sound of human voices. ...> Full Article |
 | One of the most significant questions facing marine ecologists today, is just how much of an impact global variations in the environment are having on the dispersal of larval and juvenile marine species from open oceans to coral reefs. Previously, tracking how fish larvae migrate was done through direct observation by divers on older larvae found near the reefs, after they'd spent weeks to months in the plankton. This method did not permit divers to follow small larvae, diving larvae or larvae as they returned to the reefs at night. How tiny coral reef fish larvae locate the reef habitat across vast expanses of water has remained an enduring mystery. ...> Full Article |
 | Outbreaks of the notorious crown of thorns starfish now threaten the "coral triangle," the richest center of coral reef biodiversity on Earth, according to recent surveys by the Bronx Zoo-based Wildlife Conservation Society and ARC Centre of Excellence for Coral Reef Studies. ...> Full Article |
 | At first, the fishing industry may be happy to hear the results of a climate change study by Bangor University that will be published by the scientific journal 'Global Change Biology': rising water temperatures at the bottom of the seas can lead to an increase in the diversity of fish that is found in UK waters. ...> Full Article |
 | A gigantic palm that flowers itself to death has been discovered in Madagascar. This previously unknown genus is entirely new to science and has been named Tahina spectabilis in the latest issue of the Botanical Journal of the Linnean Society, which is Malagasy for "blessed" or "to be protected", and is also one of the given names of Anne-Tahina Metz, the daughter of the discoverer of the palm. ...> Full Article |
 | A newly discovered parasite so dramatically transforms its host, an ant, that the ant comes to resemble a juicy red berry, ripe for picking, according to a report accepted for publication in The American Naturalist. This is the first example of fruit mimicry caused by a parasite, the co-authors say. ...> Full Article |
 | Wildebeest Whether you are dealing with the number of wildebeest on the Serengeti or the number of malaria parasites in the human body, new research shows the same ecological framework determines breeding numbers and population size. New research published today (15 January) in Proceedings of the National Academy of Sciences by a Biotechnology and Biological Sciences Research Council (BBSRC) Fellow shows that the same community ecology principles that determine how different animal species on the savannah affect each other's population sizes through competition for food and hunting by predators also affect parasite species interacting within the microcosm of a single host. ...> Full Article |

 | Swedish researchers report that birds captured in the hyperboreal tundra, in connection with the tundra expedition "Beringia 2005," were carriers of antibiotics-resistant bacteria. These findings indicate that resistance to antibiotics has spread into nature, which is an alarming prospect for future health care. ...> Full Article |

 | Since its discovery, the annual migration of eastern North American monarch butterflies has captivated the human imagination and spirit. That millions of butterflies annually fly a few thousand miles to reach a cluster of pine groves in central Mexico comprising just 70 square miles is, for many, an awesome and mysterious occurrence. However, over the past two decades, scientists have begun to unveil the journey for what it is: a spectacular result of biology, driven by an intricate molecular mechanism in a tiny cluster of cells in the butterfly brain. ...> Full Article |
 | With the aid of various alarm calls the Siberian jay bird species tells other members of its group what their main predators-hawks-are doing. The alarm calls are sufficient for Siberian jays to evince situation-specific fleeing behaviors, which enhances their chances of survival. This discovery, being published by Uppsala University researcher Michael Griesser in the journal Current Biology, shows for the first time that animals can assess and communicate about the behavior of predators. ...> Full Article |

Tiny roundworms called Caenorhabditis elegans have a rather uncomplicated method for finding food: They wriggle and turn and explore new territory until they find something edible, and then they stay the course until the food disappears. But despite the worm's simple nervous system, researchers have been unable to figure out exactly how a stimulus such as food odor gets converted into a more complex, long-lasting behavior like foraging. Now, using tools borrowed from the computer industry, Rockefeller University researchers have created tiny devices that allow them to watch in real time as information travels from one worm neuron to another. Their findings - that one of the long-studied olfactory neurons has a totally different mode of operation than expected - uncover a surprising similarity between the worm's neural network and our own.

 | 38-year-old researcher Kasper Thorup, University of Copenhagen, has come a step closer to unravelling the secret of how migration birds navigate across large distances. He has followed the birds' passage across USA from small sports planes. The results are now being published in the scientific journal PNAS. ...> Full Article |
 | Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. When seen in the lab, they are nothing like the long upper arm bones of any other mammal, says Samantha Hopkins, a paleontologist at the University of Oregon. ...> Full Article |

 | When resources are scarce, who you know and where you're positioned on the social totem pole affects how far you'll go to search for food. At least that's the case with African elephants, according to a study led by ecologists at the University of California, Berkeley, who collaborated with researchers at Save the Elephants, a non-profit research organization based in Kenya, and at the University of Oxford in England. ...> Full Article |
