  • Evolution And Evolvability Wednesday, December 3, 2008 @ 3:10PMEvolutionary biologists are increasingly interested in the "evolvability" of populations and their traits. This opinion piece examines different interpretations that have been put on the idea of evolvability, which differ in the timescales over which the concept is applied. For some, evolvability characterises the potential for future adaptive mutation and evolution.
  • Genetic Compatibility And Hatching Success In The Sea Lamprey (Petromyzon Marinus). Is There A Better Half? Wednesday, December 3, 2008 @ 2:11PMIt often assumed that the quality of a potential mate in terms of how their genes affect their offspring quality is a fixed feature of each individual. However, it is becoming increasingly apparent that this is not always the case, and that mates may vary in compatibility more than in quality.
  • Latent Inhibition Of Predator Recognition By Embryonic Amphibians Wednesday, December 3, 2008 @ 2:11PMIt is crucial for prey to be able to learn to discriminate between predators and non-predators. While this task can be challenging and dangerous for prey animals, it appears that amphibian embryos have found a way to get a head start on their homework.
  • Revisiting The Cognitive Buffer Hypothesis For The Evolution Of Large Brains Wednesday, December 3, 2008 @ 2:10PMWhen it comes to the brain, the popular view is that bigger is better. But why should a large brain facilitate the survival of animals in the wild? A popular answer is that a large brain buffers individuals against environmental challenges by facilitating the construction of behavioural responses, a theory known as the cognitive buffer hypothesis.
  • Diversification Trajectories And Evolutionary Life-history Traits In Early Sharks And Batoids Wednesday, December 3, 2008 @ 1:11PMThe timing of the early diversification of modern sharks and batoids (Neoselachii) is crucial to understand their early evolutionary history. However, different concepts of this timing exist, which are related to discrepancies in taxonomic and phylogenetic interpretations. Statistic analyses performed in this study show that a burst in neoselachian diversity occurred very early ca.
  • Echolocating Bats Emit A Highly Directional Sonar Sound Beam In The Field Wednesday, December 3, 2008 @ 1:11PMBats use echolocation to navigate and find prey at night. The width of the echolocation sound beam determines how broad an angle bats perceive. Using multi-microphone recordings we determined for the first time beam width for a bat, Myotis daubentonii, flying in the wild. The bats emitted highly directional narrow sound beams in the wild, but significantly broader beams in the lab.
