• Genetic Analysis Of Historic Western Great Lakes Region Wolf Samples Reveals Early Canis ...
  Thu, 23 October 2008
  The genetic status of wolves in the western Great Lakes region (WGLR) has received increased attention following their removal from the U.S. Endangered Species List. We examined the genetic composition of three historic wolves from the WGLR and showed that they were genetically similar to the present animals in the region, ...
• Sleeping Gulls Monitor The Vigilance Behaviour Of Their Neighbours
  Thu, 23 October 2008
  Individuals in groups are often thought to scan their surroundings for predation threats independently of one another. However, foragers could monitor the vigilance level of their neighbours to prevent cheating and to gather information about incipient predation risk. Here, I examined changes in vigilance in sleeping gulls ...
• Reproductive Skew In Female Common Marmosets: What Can Proximate Mechanisms Tell Us Abou ...
  Thu, 23 October 2008
  Common marmosets are New World monkeys that exhibit high reproductive skew, or an unequal distribution of reproduction, among females: typically, only 1-2 dominant females breed within each group, while subordinate females are reproductively inactive. We review an extensive data set from field and laboratory studies of m ...
• The Relevance Of Brain Evolution For The Biomedical Sciences
  Thu, 23 October 2008
  Understanding the human brain in health and disease is an important endeavour in biomedical research. Much of the research, however, happens in other animals. The extrapolation of results found in other animals to humans is crucially dependent on a correct understanding of brain evolution.
• Extreme Endurance Flights By Landbirds Crossing The Pacific Ocean: Ecological Corridor R ...
  Thu, 23 October 2008
  Imagine exercising nonstop for a week. The bar-tailed godwit (Limosa lapponica), a sleek shorebird, does just that and more. With the help of miniaturized satellite transmitters godwits were tracked flying between Alaska and New Zealand, directly across the central Pacific Ocean. Constantly flapping their wings and takin ...
• Hippocampal Volume And Neuron Numbers Increase Along A Gradient Of Environmental Harshne ...
  Thu, 23 October 2008
  Spatial memory is important for animals that store food. These animals living in harsh environments rely strongly on food-stores and should have better memories to support cache retrieval and should benefit from more neurons within larger hippocampi, the part of the brain involved in spatial memory. We found that hippoca ...
• Seabird-Driven Shifts In Arctic Pond Ecosystems
  Thu, 23 October 2008
  Seabirds are sensitive bellwethers of global environmental change, yet census data are rare. Here, we demonstrate that seabird population dynamics can be reconstructed over long-term timescales. Using dated pond sediments, we show that a colony of Arctic seabirds has experienced climate-induced increases in population in r ...

  Thu, 23 October 2008
  PharmaCom BioVet, Inc. (PINKSHEETS: PHMB) is pleased to announce its plans with IsoTherapeutics Group, LLC to explore the latest ground-breaking direct injection liquid brachytherapy therapeutic radioisotope procedures for use within its canine cancer treatment centers. As part of its plans for state- ...
• Migration Strategy And Divergent Sexual Selection On Bird Song
  Thu, 23 October 2008
  Although all bird song has two functions, to attract a mate and repel rivals, the relative importance of these functions may vary between populations. We found in that migratory birds attracting a mate is most important function of song, while in resident populations it is more important to repel rivals. In both cases song ...
• Female Spiders Benefit From Killing And Consuming Males In Nature
  Wed, 22 October 2008
  A team of researchers from Spain and the US led an investigation to reveal the extent to which sexual cannibalism occurs in nature and whether this behavior benefits female spiders. According to their results, in a natural population of burrowing wolf spiders, one third of the females kill males rather than mating wi ...
