  • Birds roosting in large groups less likely to contract west nile virus

    Zoology News -- ScienceDaily

    Although it would seem logical that large numbers of roosting birds would attract more mosquitoes that carry West Nile virus and contract the disease when bitten, recent research has found the opposite to be true. That is, when large groups of birds roost together the chances that an individual bird will get bitten by mosquitoes carrying West Nile virus and subsequently contract the disease actually go down.

  • Recognition and Response to Native and Novel Predators in the Largespring mosquitofish, Gambusia geiseri

    24 Oct 2014 | 9:36 am
    In this study, we examined whether the Largespring mosquitofish, Gambusia geiseri exhibited antipredator behavior and/or an elevation of circulating stress hormones (cortisol) to visual and chemical cues from a native predator, a novel predator, or a non‐predatory control fish. Prey showed the most pronounced antipredator response to the native predator treatment, by moving away from the stimulus, while the prey showed no significant changes in their vertical or horizontal position in response to the novel or non‐predator treatments. We also found no significant difference in…

    With new nano-sized acoustic transmitters, scientists followed the pathways of loggerhead turtle hatchlings. According to the study, local oceanic conditions are believed to drive the evolution of some unique swimming behaviors.
  • Retaining forests where raptors nest can help to protect biodiversity

    23 Oct 2014 | 7:07 am
    Raptors can affect the distribution of other species and they can also be used to find forests with high biodiversity value, researchers say. Predators influence decisions on conservation actions because they awake a remarkable interest in the society. However, favoring just predators in conservation can also mislead the scarce funding invested in nature conservation.
  • Sex-loving, meat-eating reptiles have shorter lives

    23 Oct 2014 | 6:18 am
    The health risks and benefits of vegetarianism have long been discussed in relation to the human diet, but newly published research reveals that it’s definitely of benefit to the reptile population. That, and being less sexually active. The research team investigated how longevity of 1,014 species of scaled reptiles is influenced by key environmental characteristics and by their feeding and sexual habits.
  • Chamber of secrets: Cell organization influences ability to communicate

    23 Oct 2014 | 6:18 am
    Cells can huddle to communicate within a restricted group, scientists have found. The study is the first demonstration that the way cells organize themselves influences their ability to communicate. The researchers propose that this strategy, which they discovered in developing zebrafish, could be much more widespread, influencing processes like wound repair, organ formation and even cancer.

  • Trinity Zoologists Champion a Clever Conservation Solution: 'Vulture Restaurants'

    Zoologists from the School of Natural Sciences at Trinity College Dublin are proposing an ingenious idea to help conserve populations of African white-backed vultures. The iconic birds, which play a critical role in sustaining healthy ecosystems, may need to dine for free in human-staffed 'vulture restaurants' if they are to survive spells of food scarcity in Swaziland and neighbouring countries.

  • Spy on penguin families for science

    Online volunteers are being asked to classify images of penguin families to help scientists monitor the health of penguin colonies in Antarctica. Recent evidence suggests that populations of many species of penguin, such as chinstrap and Adelie, are declining fast as shrinking sea ice threatens the krill they feed on.

  • The role of juvenile hormone in dominance behavior, reproduction and cuticular pheromone signaling in the caste-flexible epiponine wasp, Synoeca surinama

    23 Oct 2014 | 4:00 pm
    Conclusions: The endocrine profile of S. surinama shows surprising differences from those of other caste-flexible wasps, although a rise in JH titers in replacement queens is a common theme. Extensive remodeling of hormone functions is also evident in the highly eusocial bees, which has been attributed to the evolution of morphologically defined castes. Our results show that hormones which regulate caste-plasticity can lose these roles even while caste-plasticity is preserved. (Source: Frontiers in Zoology)

  • Foraging Benefits in a Colour Polymorphic Neotropical Orb Web Spider

    20 Oct 2014 | 3:01 pm
    Abstract Conspicuous body colouration in sedentary predators such as orb web spiders seems paradoxical as potential prey can see and avoid the webs. Several studies have demonstrated that rather than deterring prey, the colours act as sensory traps for flower‐seeking insects. In chromatically polymorphic species, the existence of more than one colour morph may lead to differing levels of prey attraction. To explore these issues, we studied a neotropical orb web spider, Verrucosa arenata, which shows colour polymorphism with predominantly white or yellow abdomen colours. We asked whether a…

    ReptileApartment.com - "It's Not a desire; it's an obsession to share our knowledge with people interested in herpetoculture." Tarantulas have been kept as pets for numerous years. I’m not sure anyone can definitively say when this began. I imagine it’d be somewhat similar to how human primates began keeping reptiles as pets. A scientist, studying one aspect or another of the Theraphosidae family began looking at their charges as more than just a subject of study. Being knowledgable of their preferred environment they began keeping them as pets. Maybe somewhere in…
