  • Insect mating behavior has lessons for drones

    Male moths locate females by navigating along the latter's pheromone (odor) plume. Two strategies are involved: males must find the outer envelope of the pheromone plume, and then head upwind. Can understanding such insect behavior be useful for robotics research? Yes, according to an entomologist, whose research using computer simulations shows that such insect behavior has implications for airborne robots (drones) that ply the sky searching for signature odors.
  • Miller's Lament

    28 May 2015 | 10:33 pm
    When I sit down with old friends who, like me, are in their 70s, I sometimes ask: "If you could live your life again, would you do anything differently?" Most just scratch their heads and say, "I dunno." Recently, I told three old friends that I would do one thing differently: I would get a middle initial-either Q or X-to distinguish myself from the many Stephen Millers who write books.
  • Colour and Escape Behaviour in Polymorphic Populations of an Aposematic Poison Frog

    MedWorm: Zoology
    29 May 2015 | 3:26 pm
    Abstract The phenomenon of aposematism, or the pairing of antipredator defence with conspicuous or distinctive signals, serves as an excellent example of how traits act in concert to shape fitness. Not only does this complex phenotype require the integration of multiple traits, it alters the fitness pay‐offs of yet others. The protection offered by aposematism may, for example, reduce the costs associated with foraging or sexual display. Thus, well‐protected aposematic lineages should be bolder, more active and less likely to respond to perceived threats of predation than more cryptic…

  • “It is our aim to stop private keeping of exotic mammals, keeping wild animals in circuses, and of course illegal trade” – Interview with Joris Verbruggen, Outplacement Coordinator, AAP Rescue Centre for Exotic Animals

    Many exotic animals live in Europe kept in poor conditions. The AAP Rescue Centre for Exotic Animals works for these animals to be placed in appropriate conditions. They rescue animals that are used and utilised by tourism and entertainment industries and also that had been kept illegally as pets. The AAP Foundation has shelters in the Netherlands and in Spain. The main aim is to place these animals to permanent homes from these shelters. They cooperate with similar organizations to increase their efforts to improve animal welfare. The AAP also influences policy making to facilitate this…

  • Godwits are flexible, when they get the chance

    29 May 2015 | 5:35 am
    Black-tailed godwits are able to cope with unpredictable weather, a thorough analysis finds, following the extraordinary spring of 2013 in Belgium. That year, godwits were surprised by an exceptionally cold spring upon their return to the Netherlands. Nevertheless the godwits had a particularly productive breeding season that year, authors noted.
  • Unmanned aerial vehicle used to study gray whales from above

    28 May 2015 | 1:31 pm
    Scientists are using an unmanned aerial vehicle to take very precise overhead images of migrating gray whale mothers and calves. This research will help scientists understand how environmental conditions control the reproductive success of individual whales and ultimately of the population.
  • Dinosaurs were likely warm-blooded

    28 May 2015 | 11:09 am
    Dinosaurs grew as fast as your average living mammal, according to a new research article. The article is a re-analysis of a widely publicized 2014 Science paper on dinosaur metabolism and growth that concluded dinosaurs were neither ectothermic nor endothermic -- terms popularly simplified as 'cold-blooded' and 'warm-blooded' -- but instead occupied an intermediate category.
  • Genetic analysis of the American eel helps explain its decline

    28 May 2015 | 9:42 am
    The numbers of American eels in freshwater areas have been decreasing rapidly but scientists have been puzzled as to why the fish can't recolonize. Now, a new look at eel genetics finds that there are differences between eels that feed in freshwater and eels that feed in brackish environments that were previously thought to be genetically interchangeable.

  • Myc regulates programmed cell death and radial glia dedifferentiation after neural injury in an echinoderm

    29 May 2015 | 3:25 pm
    Conclusions: In this study, we show that Myc overexpression is required for proper dedifferentiation of radial glial cells and for triggering the programmed cell death in the vicinity of the injury. Myc is thus the first transcription factor, whose functional role has been experimentally established in echinoderm regeneration. (Source: BMC Developmental Biology)

  • The Aurora A-HP1γ pathway regulates gene expression and mitosis in cells from the sperm lineage

    28 May 2015 | 4:00 pm
    Conclusions: These results support the idea that phosphorylation of HP1γ by Aurora A plays a role in the regulation of gene expression and mitotic cell division in cells from the sperm lineage and in early embryos. Combined, this data is relevant to better understanding the function of HP1γ in reproductive biology. (Source: BMC Developmental Biology)
  • Scouts, forests, and ticks: impact of landscapes on human-tick contacts

    Publication date: Available online 27 May 2015 Source:Ticks and Tick-borne Diseases Author(s): Mathilde De Keukeleire , Sophie O. Vanwambeke , Elysée Somassè , Benoît Kabamba , Victor Luyasu , Annie Robert Just as with forest workers or people practicing outdoor recreational activities, scouts are at high risk for tick bites and tick-borne infections. The risk of a tick bite is shaped not only by environmental and climatic factors but also by land management. The aim of this study was to assess which environmental conditions favour scout-tick contacts, and thus to better understand how…

  • A Simple but Splendid Information System at Děčín Zoo, Czech Republic

    10 May 2015 | 6:08 am
    A regular example of how zoological and botanical gardens provide information to the public and create passive learning experiences is the installation of information panels and signs which can raise the interest of the visiting public of all ages. This type of education is often referred to as informal learning at the zoo. Compared with some formal learning techniques – especially with talks with keepers – it is not as efficient as those, but it is worth trying to improve them as well. Hereinafter I am going to provide a brief overview about the information system and unusual graphic…
  • Feeding Anteaters Without Ants

    29 Apr 2015 | 12:13 pm
    By Rebeka Pécsi, zookeeper, Jászberény Zoo, Hungary Keeping giant anteaters (Myrmecophaga tridactyla) was never an easy task. These magnificent beings were always unique additions to any collection. But even now, zoos think twice whether to keep an anteater, for there are many special needs that have to be fulfilled. The biggest amongst them is their diet.In the past, feeding anteaters was only about giving them insectivore food, because they eat termites and ants in the wild. That is true, but later discoveries have shown that they often eat fallen fruits from the ground and take soil…

Some stock sites provide good opportunities even for zoo photographers. Of course, it is not the way to become a millionaire, but you can earn a non-negligible amount with time and a lot of patience. First, I am going to introduce the world of stock photography in a nutshell. It means the supply of photos which are licensed for specific uses. Customers do not have to hire a photographer; they can pick the desired…
