Data from: Infection reduces anti-predator behaviors in house finches
Infectious diseases can cause host mortality through direct or indirect mechanisms, including altered behavior. Diminished anti-predator behavior is among the most-studied causes of indirect mortality during infection, particularly for systems in which a parasite's life-cycle requires transmission from prey to predator. Significantly less work has examined whether directly-transmitted parasites and pathogens also reduce anti-predator behaviors. Here we test whether the directly-transmitted bacterial pathogen, Mycoplasma gallisepticum (MG), reduces responses to predation-related stimuli in house finches Haemorhous mexicanus. MG causes conjunctivitis and reduces survival among free-living finches, but rarely causes mortality in captivity, suggesting a role for indirect mechanisms. Wild-caught finches were individually housed in captivity and exposed to the following treatments: 1) visual presence of a stuffed, mounted predator (a Cooper's hawk Accipiter cooperii) or control object (a vase or a stuffed, mounted mallard duck Anas platyrhynchos), 2) vocalizations of the same predator and non-predator, 3) approach of a researcher to enclosures, and 4) simulated predator attack (capture by hand). MG infection reduced anti-predator responses during visual exposure to a mounted predator and simulated predator attack, even for birds without detectable visual obstruction from conjunctivitis. However, MG infection did not significantly alter responses during human approach or audio playback. These results are consistent with the hypothesis that predation plays a role in MG-induced mortality in the wild, with reduced locomotion, a common form of sickness behavior for many taxa, as a likely mechanism. Our results therefore suggest that additional research on the role of sickness behaviors in predation could prove illuminating.
First record of anti-predator behavior in the gall-forming aphid Mordwilkoja vagabunda
<p>The gall-forming aphid <em>Mordwilkoja vagabunda</em> has been an outgroup in molecular studies of the evolution of social behavior in the <em>Pemphigus </em>genus, but <em>Mordwilkoja</em> aphids have not previously been assayed for social behavior, such as altruistic defense. This study reports experiments carried out in July in Ithaca, NY, USA, in which nymphs (immature aphids) of <em>M. vagabunda</em> were video recorded under a stereo microscope while they encountered pyralid moth larvae in a plastic arena. <em>M. vagabunda</em> nymphs of all instars<em> </em>used their legs to claw moth larvae while pressing their rostrums against the larvae, possibly to pierce the cuticle. Many of the attacking aphids were alatoid nymphs, rather than the specialized first instar soldiers typically observed in <em>Pemphigus</em> species. <em>M. vagabunda</em> nymphs moved in bursts that sometimes became synchronized among several aphids in the same vicinity. These synchronized, rhythmic movements may be anti-predator defense strategies comparable to the collective twitching and kicking response observed in colonies of <em>Aphis nerii</em> and other aphid species. Defensive behaviors by <em>M. vagabunda</em> nymphs may be altruistic fortress defense strategies which maximize inclusive fitness of the clone.</p>

Innate anti-predator behavior can promote infection in fish even in the absence of predators
<p>Natural enemies - predators and parasites - largely shape the dynamics of ecosystems. It is known that anti-predator and anti-parasite defense can be mutually conflicting, however consequences of this trade-off for the regulation of infection burden in animals are still poorly understood. We hypothesize that even in the absence of cues from predators, innate anti-predator behavior ("ghost of predation past") interferes with defense against parasites and can enhance the infection risk. As a case study, we explore interactions between a commercial species, the rainbow trout <i>Oncorhynchus mykiss,</i> and its parasite, the trematode eye-fluke <em><span>Diplostomum pseudospathaceum. </span></em>Fish-parasite interactions were tested in compartmentalized tanks where shelters and parasites were presented in different combinations providing various conditions for microhabitat choice and territorial behavior. Shelters were attractive and contestable despite the absence of predators and presence of parasites. The individuals fighting for shelters acquired more than twice the number of cercariae as compared to those in infected shelter-free compartments. Most infected were subordinate fish with a higher ventilation rate. Fish possessing shelters were less vulnerable to parasites than fighting fish. Grouping reduced the infection load, although less efficiently than sheltering. Our data demonstrate that the innate anti-predator behavior can undermine anti-parasite tactics of the fish and result in higher infection rates. Using our empirical results, we construct a mathematical model which predicts that enriching the environment in fish farming will be beneficial only when a large number of shelters is provided. Using insufficient number of shelters will increase the parasite burden in the fish.</p>

Anti-predator behavior in two brown frogs: differences in the mean behaviors and in the structure of animal personality variation
<p>Predators are a major source of selection and preys have evolved the ability to flexibly respond to them. These responses often vary among species, because of their different evolutionary history, and among individuals, because of their different experiences. We analyzed both these sources of behavioral variation in two closely related brown frogs, <em>Rana dalmatina </em>and <em>R. latastei</em>. We raised tadpoles either with or without predators and tested them in open field trials both with and without predators. The effects of the raising environment were similar in the two species, whereas the effects of the testing arena differed. Both species decreased activity and increased speed and tortuosity with predators, but <em>R. dalmatina </em>moved always more and faster than <em>R. latastei </em>and it showed higher plasticity, larger variation among and within individuals, and relatively higher values in repeatability.</p>
