  • Climate modeling may have missed something: Aquatic creatures mix ocean water by swimming

    23 Nov 2009 | 11:00 am
    Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.

  • Deep-sea world beyond sunlight: Explorers census 17,650 ocean species on edge of black abyss

    23 Nov 2009 | 8:00 am
    Scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight -- creatures that somehow manage a living in a frigid black world down to 5000 meters (three miles) below the ocean waves.

  • Sea stars bulk up to beat the heat

    23 Nov 2009 | 8:00 am
    A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide.

  • Butterfly proboscis to sip cells

    21 Nov 2009 | 9:00 pm
    A butterfly's proboscis looks like a straw -- long, slender and used for sipping -- but it works more like a paper towel, according to researchers. They hope to borrow the tricks of this piece of insect anatomy to make small probes that can sample the fluid inside of cells.

  • Why bird flu has not caused a pandemic

    21 Nov 2009 | 8:00 am
    Bird flu viruses would have to make at least two simultaneous genetic mutations before they could be transmitted readily from human to human, according to new research.

  • An analysis of levels of infectious pancreatic necrosis virus in Atlantic salmon, Salmo salar L., broodstock in Scotland between 1990–2002

    19 Nov 2009 | 3:00 pm
    Throughout this study period the prevalence of infectious pancreatic necrosis virus (IPNV) in Scottish farmed Atlantic salmon was high in the marine environment but relatively low in fresh water. In order to minimize the risk of vertical transmission of infection from parent to progeny, all IPNV infected broodstock populations had to undergo testing of all fish for the virus at the time of stripping and eggs from positive parents were destroyed. Between 1990 and 2002 over 68 000 Atlantic salmon broodfish were individually screened for IPNV by cell culture isolation and enzyme linked…

  • Histology and ultrastructure of the salivary glands and salivary pumps in the scorpionfly Panorpa obtusa (Mecoptera: Panorpidae)

[mdash]Acta Zoologica (Stockholm) xx:xx[ndash]xx The morphology, histology and ultrastructure of the salivary glands and salivary pumps in the scorpionfly Panorpa obtusaCheng 1949 were investigated using light microscopy and scanning and transmission electron microscopy. The salivary glands display a distinct sexual dimorphism. The female has only two small sac-like glands located in the prothorax, while the male possesses six long tubular…

  • The Use of Torpor in Reproductive Female Hemprich’s Long‐Eared Bats (Otonycteris hemprichii)

    19 Nov 2009 | 12:18 pm
    Physiological and Biochemical Zoology, Volume 0, Issue 0, Page 000, Latest Articles. Abstract We investigated the patterns of torpor use and body temperature (Tb) in reproductive Hemprich’s long‐eared bats (Otonycteris hemprichii; body mass ∼20 g) in the central Negev Desert highlands. We hypothesized that Tb regulation in female O. hemprichii during reproduction is shaped by a trade‐off between the energy and temperature requirements of embryo and pup growth and the mother’s own need to use torpor and passive rewarming to save energy and water. We predicted that patterns of torpor…

  • Big animalivorous microbats

    19 Nov 2009 | 1:23 am
    Time only for a picture-of-the-day post... here are portraits of the big animalivorous microbats Otomops (a molossid, of course*), Cheiromeles (also a molossid) and Vampyrum (a phyllostomid). The pic is from Freeman (1984), but you might notice that two of the drawings are based on the photos featured in Walker's Mammals of the World.

  • Hippos are photographed biting a crocodile to death

    17 Nov 2009 | 1:21 am
    You've probably seen - presumably on TV - Nile crocs Crocodylus niloticus interacting with Common hippos Hippopotamus amphibius (if you've seen it in real life, lucky you). By and large the two seem to keep apart. Having said that, there are certainly photos of the two sharing the same sandbanks. And then there are those instances of hippos scaring crocs away from carcasses, the weird reports of hippos mouthing and chewing the backs and tails of resting crocodiles, and those cases where crocodiles have been seen to walk or run across hippos' backs. What can certainly be said to be the most…

  • The Tet Zoo tour of Libya (part III): frasercots and Tripoli Zoo

    16 Nov 2009 | 1:57 am
    By now you might have read my two previous articles (part I, part II) on the assorted tetrapods I encountered in Libya last month. Here's the third and final part in the series [image below shows chital at left, melanistic fallow top-centre, nilgai bottom-centre, blackbuck at right]. It's a bit unusual for a Tet Zoo article, as it contains a whole paragraph of boring travel-writing stuff, but I hope you can grit your teeth and get through this - the meat and potatoes on obscure subspecies and so on is delivered towards the end, I promise. So, without further ado... Read the rest of this…

  • Richard Dawkins and the crappy 'humanoid dinosaurs' that just won't die

    11 Nov 2009 | 4:02 am
    Regular readers will know that I'm not exactly a fan of the idea - discussed here and there in the technical (Russell & Séguin 1982, Russell 1987), popular (Hecht 2007, Socha 2008, Naish 2008) and speculative literature (McLoughlin 1984, Magee 1993) - that non-avian theropod dinosaurs might have evolved into humanoids had they not bought the farm 65 million years ago [image below by Matt Collins]. The hypothetical (emphasis: hypothetical) evolution of big brains, intelligence and so on among imaginary post-Cretaceous deinonychosaurs is not (in my opinion) all that unreasonable, and I base…

  • DIY Ecology: 4 Ways To Engineer A New Earth

    Mike
    22 Nov 2009 | 10:46 am
    (Image via: NASA / Jet Propulsion Laboratories) The planet has a fever – and how we cool it down is the challenge of the century.  How do we start? According to advocates of a branch of scientific techniques known as geo-engineering, the only approach is to think big – and change the planet’s ecosystem before it changes us. Are we ready for these four scientific experiments on a truly global scale? (Image via: Greenlaunches) The Earth is heating up because of the greenhouse effect – and one way to short-circuit this process is to prevent the heat getting into our…

    (Images via: Field of Love, Online Web Library, Halo Halo, Boing Boing, Moolf, Media Dis-N-Dat) Whether getting attacked by a larger predator, being harmed by man, suffering from disease or simply being injured on accident, there are many different ways in which animals can get hurt in the wild. While many animals are resilient following injury, the odds of survival certainly improve when researchers are able to help out. Take animal prosthetics and artificial limbs as an example. From artificial turtle flippers to new beaks for bald eagles to replacement dolphin tails, the development of…

  • ReBurbia: Designers Take on Greening the American Suburb

    Delana
    18 Nov 2009 | 10:00 am
    In the past few years, we’ve seen some interesting shifts take place between urban and suburban dwellers. Gas prices have risen and the life of the commuter has gotten to be too expensive for many; massive foreclosures have prompted countless former homeowners to downsize to urban apartments; and a move toward a greener lifestyle has driven a growing segment to move to the inner cities where owning a car isn’t a necessity. So for the first time since their inception, we’re seeing the suburbs becoming the less desirable place to live. But the homes, supermarkets and big box…
