dynamic visual cues induce jaw opening and closing by tiger beetles during pursuit of prey.in dynamic locomotory contexts, visual cues often trigger adaptive behaviour by the viewer, yet studies investigating how animals determine impending collisions typically employ either stationary viewers or objects. here, we describe a dynamic situation of visually guided prey pursuit in which both impending prey contact and escape elicit observable adaptive behaviours in the pursuer, a predatory beetle. we investigated which visual cues may independently control opening and closing of the beetl ...201425376803
behavioral responses to mammalian blood odor and a blood odor component in four species of large carnivores.only little is known about whether single volatile compounds are as efficient in eliciting behavioral responses in animals as the whole complex mixture of a behaviorally relevant odor. recent studies analysing the composition of volatiles in mammalian blood, an important prey-associated odor stimulus for predators, found the odorant trans-4,5-epoxy-(e)-2-decenal to evoke a typical "metallic, blood-like" odor quality in humans. we therefore assessed the behavior of captive asian wild dogs (cuon a ...201425383706
prioritizing tiger conservation through landscape genetics and habitat linkages.even with global support for tiger (panthera tigris) conservation their survival is threatened by poaching, habitat loss and isolation. currently about 3,000 wild tigers persist in small fragmented populations within seven percent of their historic range. identifying and securing habitat linkages that connect source populations for maintaining landscape-level gene flow is an important long-term conservation strategy for endangered carnivores. however, habitat corridors that link regional tiger p ...201425393234
instability-induced pattern formation of photoactivated functional polymers.since the pioneering work of turing on the formation principles of animal coat patterns [turing am (1952) phil trans r soc lond b 237(641):37-72], such as the stripes of a tiger, great effort has been made to understand and explain various phenomena of self-assembly and pattern formation. prominent examples are the spontaneous demixing in emulsions, such as mixtures of water and oil [herzig em, et al. (2007) nat mater 6:966-971]; the distribution of matter in the universe [kibble twb (1976) j ph ...201425404346
the three-dimensional morphological effects of captivity.many captive animals are fed diets that are drastically different in mechanical properties than their wild diet. most captive pantherines are fed a nutritionally supplemented diet consisting almost entirely of ground meat. while many zoos supplement this diet with bones, the fact remains that large captive felids are fed diets that require substantially less masticatory effort than those of their wild counterparts. the osteological effects of this dietary difference have not been fully evaluated ...201425409498
the neural circuit mechanisms underlying the retinal response to motion reversal.to make up for delays in visual processing, retinal circuitry effectively predicts that a moving object will continue moving in a straight line, allowing retinal ganglion cells to anticipate the object's position. however, a sudden reversal of motion triggers a synchronous burst of firing from a large group of ganglion cells, possibly signaling a violation of the retina's motion prediction. to investigate the neural circuitry underlying this response, we used a combination of multielectrode arra ...201425411485
ontogenetic phase shifts in metabolism in a flounder paralichthys olivaceus.size-scaling metabolism is widely considered to be of significant importance in biology and ecology. thus, allometric relationships between metabolic rate (vo2) and body mass (m), vo2 = a(i)mb, have long been a topic of interest and speculation. it has been proposed that intraspecifically metabolic rate scales isometrically or near isometrically with body mass during the early life history in fishes, invertebrates, birds and mammals. we developed a new perspective on intraspecific size-scaling m ...201425412451
