  • Unusually elastic protein found by researchers; may have originated in cnidarian elastomer

    Zoology News -- ScienceDaily
    23 Jan 2015 | 8:07 am
    An unusually elastic protein has been discovered in one of the most ancient groups of animals, the over 600-million-year-old cnidarians. The protein is a part of the "weapons system" that the cnidarians use: a kind of harpoon launched from their body at extremely high speed. The discovery of the hitherto unknown protein in the freshwater polyp Hydra suggests that the molecular mechanism of elasticity could have originated in the cnidarians and evolved to discharge a deadly weapon. Due to the similarity of the protein's amino acid sequence to spidroin of spider silk, the researchers dubbed the…

  • Warming seas decrease sea turtle basking

    23 Jan 2015 | 7:22 am
    Green sea turtles may stop basking on beaches around the world within a century due to rising sea temperatures, a new study suggests. Basking helps the turtles regulate body temperature and may aid their immune system and digestion. By analyzing six years of turtle surveys and 24 years of satellite data, researchers have found the turtles bask more often when sea surface temperatures are lower. This vital behavior may cease globally by 2102 if global warming trends continue.
  • Bad reputation of crows demystified

    23 Jan 2015 | 5:18 am
    In literature, crows and ravens are a bad omen and are associated with witches. Most people believe they steal, eat other birds' eggs and reduce the populations of other birds. But a new study, which has brought together over 326 interactions between corvids and their prey, demonstrates that their notoriety is not entirely merited. The study analyzed the impact of six species of corvid on a total of 67 species of bird susceptible to being their prey, among which are game birds and passerine birds.
  • Hidden infection shortens life in birds

    23 Jan 2015 | 5:17 am
    Mild infections without symptoms of illness can still lead to serious consequences by reducing the lifespan of the infected individuals, research shows. A new study has been carried out on malaria-infected migratory birds. The infection is thought to speed up the aging process by shortening the telomeres (i.e., the chromosomes ends) at a faster rate and thereby accelerating senescence. 
  • Sexually-transmitted diseases: Do multiple partners mean more immunity?

    23 Jan 2015 | 5:17 am
    It has been assumed that the increased transmission of sexually-transmitted diseases in the case of mating promiscuity is influential in shaping the immune system of mammals. Results of a new study demonstrate that this simple idea does not apply to rodents, and that living circumstances and the environment can be a key factor in determining variation in immune investment among mammals.

But citation practices vary widely both between and within disciplines, and once you're past the dissertation, you have far more flexibility in choosing your own citation style than you think.

    28 Dec 2014 | 10:18 am
    Dr Georg Wilhelm Steller was a German physician and naturalist participating during the early 1740s in the last of Danish explorer Vitus Bering's Russian expeditions to the Arctic waters separating Siberia's Kamchatka Peninsula from Alaska. During this expedition, Steller documented many new species of animal, including four very contentious forms that continue to arouse cryptozoological curiosity even today.

  • Differential immune responses to excretory–secretory antigens of lung-stage larvae of Schistosoma mansoni in mice and rats

    23 Jan 2015 | 3:00 pm
    Publication date: Available online 23 January 2015 Source:The Journal of Basic & Applied Zoology Author(s): Abeer M. Badr , Mohammed M.F. Al-Halbosiy , Rashika El Ridi In contrast to mice, rats are less-susceptible to infection with Schistosoma mansoni, perhaps mounting protective immune responses that provide a microenvironment unfavorable for the normal growth and survival of the parasite. Upon infection, schistosomular excretory–secretory products (ESP) trigger T helper (Th) effector cells and polarize the immune microenvironment. We investigated the differences in mouse and rat…

  • Current Sperm Competition Determines Sperm Allocation in a Tephritid Fruit Fly

    23 Jan 2015 | 10:05 am
    Abstract Sperm competition (SC) occurs when the sperm of two or more males compete for the same set of ova. Theoretical models and experimental observations indicate that the presence of rival males causes focal males to adjust sperm allocation in a given copulation. Males allocate more sperm when they perceive the presence of one rival male (SC risk), either before or during mating, or when they perceive the presence of multiple rival males before mating (previous SC intensity). Conversely, males are expected to allocate fewer sperm when they perceive the presence of rival males during…

Authored by Ron Tremper Leopard Gecko BREEDING LEOPARD GECKOS In the 1970s, when the field of herpetoculture was just emerging, “collecting” was the focus and hot topic amongst herpers. Everyone was trying to obtain various reptiles and amphibians from anywhere and keep them alive. ‘Postage Stamp’ collections, consisting of one of every type of kingsnake, ratsnake or rattlesnake, were the norm. This was the first wave of herpetoculture,…

  • Do we need non-human rights?

    21 Jan 2015 | 12:36 pm
    After summarizing the story of Sandra, I will continue my previous article more subjectively. We can experience a strong anti-zoo attitude when we look at the story from the zoos’ point of view. According to AFADA (Association of Officials and Lawyers for Animal Rights), there are no good or bad zoos, as leading zoos communicate, for living in a zoo means imprisonment for every animal and the future should be a world free of zoos. For me, the most shocking opinion on the case was that the trial should have been continued with convicting the workers of the zoo for imprisoning Sandra. I still…
  • Sandra’s Case: Is It the Breakthrough?

Most media in the world published the news at the time. The big attention is completely understandable, as this was the first case when, after several attempts, an animal received this legal state. According to animal protection NGOs, this was the great breakthrough, after several less successful attempts in other countries, which might result in a more…
  • “Improving zoo design work in any country is a challenge” – interview with Monika Fiby (ZooLex)

    10 Jan 2015 | 11:21 am
    I suppose you all know ZooLex as a very useful website dedicated to zoo design. The ZooLex Zoo Design Organization was established by Mrs. Monika Fiby, an Austrian landscape architect, to help improve the conditions of captive wild animals. The website has been developed using input from zoo professionals as part of Monika's studies in landscape architecture in 2000. Its database has grown considerably since then; now it is a must for everyone involved in zoo design work.  We asked Mrs. Fiby for an interview and she kindly answered our questions with great patience.
