• Fish Ears Are Sensitive To Sex-Change
  Thu, 27 November 2008
  Many animals, including most tropical reef fishes, start life as one sex and later change sex to function as the other. Our understanding of life history evolution, and effective fisheries management, therefore relies on our ability to detect when this fundamental transition occurs. Using the model reef fish Parapercis cyl ...
• Multiple Origins Of Deep-sea Asellota (Crustacea: Isopoda) From Shallow Waters Revealed
  Thu, 27 November 2008
  In our molecular study we reconstruct the phylogeny of deep-sea crustaceans (Isopods: Asellota), analysing more than 100 different deep-sea species. Deep-sea Asellota represent the dominating crustacean taxon in deep-sea benthos samples and show an amazing variety of bizarre and extravagant body forms, including elongated ...
• Gourds Afloat: A Dated Phylogeny Reveals An Asian Origin Of The Gourd Family (Cucurbitac ...
  Thu, 27 November 2008
  Knowing the geographic origin of certain plant groups is important for genetic improvement and conservation. We address the history of the economically important gourd family, Cucurbitaceae, using a multi-gene phylogeny for 114 of the 115 genera and 25% of the 960 species. Our results reveal an Asian origin in the Late Cre ...
• NFU Calls For Suspension Of Imports From Bluetongue Areas, UK
  Thu, 27 November 2008
  The NFU has today called for the Government and the cattle and sheep industry in Great Britain to stand together and suspend imports of cattle and sheep from areas where Bluetongue is known to be circulating in light of news that BTv1 has been detected in a batch of cattle imported from France.
• Periodic Temperature-Associated Drought/Flood Drives Locust Plagues In China
  Thu, 27 November 2008
  Global warming is currently of great concern, but its consequences on natural disasters are still unclear. Using wavelet analysis, we investigated associations of locust plagues with drought/flood and temperature in China over past millennium. We firstly found locust, drought/flood and temperature were closely associated w ...
• Hemoglobin Polymorphisms Affect The Oxygen Binding Properties In Atlantic Cod Populations
  Thu, 27 November 2008
  In this study we reveal the long-sought genetic basis of the hemoglobin polymorphism in Atlantic cod and present molecular mechanisms underlying the proposed adaptation of the cod populations to varying temperature and oxygen regimes in North Atlantic waters. The two amino acid mutations identified are located in crucial ...
• Evidence For Harvest-Induced Maternal Influences On The Reproductive Rates Of Fish Popul ...
  Thu, 27 November 2008
  A big fish in the water is worth two in the net: Most fisheries assume that a fish is a fish. Our analysis shows that a stock produces more offspring, and is therefore more sustainable, when big, old females are present because these females produce offspring that are more likely to survive (i.e., bigger is better). Theref ...
• A Phenomenological Model For The Collective Landing Of Bird Flocks
  Thu, 27 November 2008
  The presented phenomenological model for the collective landing of bird flocks accounts for the abrupt, yet highly concerted nature of the landing process, in accordance with the field observations. The theoretical description includes an inherently non-linear and self-organized tuning of the birds' landing intent.
• British Veterinary Association Adds Voice To Calls For Suspension Of Imports From Blueto ...
  Thu, 27 November 2008
  The BVA has added its voice to calls for the suspension of imports of cattle and sheep from areas where the bluetongue virus is known to be circulating. Following yesterday's announcement by Defra that BTV1 (Bluetongue Serotype 1) had been detected in five cattle imported from a Restricted Zone in the south west of Franc ...
• Protecting The Travelling Pet, British Veterinary Association
  Thu, 27 November 2008
  With an increasing number of vets now regularly dealing with pets that have travelled abroad and returned infected with diseases such as Leishmaniosis and Babesiosis, the BVA Animal Welfare Foundation has relaunched its advisory leaflet 'Taking your pets abroad - your guide to diseases encountered abroad'. Travelling with ...
