Data from: Primates adjust movement strategies due to changing food availability

Animals are hypothesized to search their environments in predictable ways depending on the distribution of resources. Evenly distributed foods are thought to be best exploited with random Brownian movements; while foods that are patchy or unevenly distributed require non-Brownian strategies, such as Lévy walks. Thus, when food distribution changes due to seasonal variation, animals should show concomitant changes in their search strategies. We examined this issue in six monkey species from Africa and Mexico: three...

Data from: Offspring of older parents are smaller—but no less bilaterally symmetrical—than offspring of younger parents in the aquatic plant Lemna turionifera

Eric J. Ankutowicz & Robert A. Laird
Offspring quality decreases with parental age in many taxa, with offspring of older parents exhibiting reduced lifespan, reproductive capacity, and fitness, compared to offspring of younger parents. These ‘parental age effects’, whose consequences arise in the next generation, can be considered as manifestations of parental senescence, in addition to the more familiar age-related declines in parent-generation survival and reproduction. Parental age effects are important because they may have feedback effects on the evolution of demographic...

Data from: Specific 50-kHz vocalizations are tightly linked to particular types of behavior in juvenile rats anticipating play

Candace J. Burke, Theresa M. Kisko, Hilarie Swiftwolfe, Sergio M. Pellis & David R. Euston
Rat ultrasonic vocalizations have been suggested to be either a byproduct of physical movement or, in the case of 50-kHz calls, a means to communicate positive affect. Yet there are up to 14 distinct types of 50-kHz calls, raising issues for both explanations. To discriminate between these theories and address the purpose for the numerous 50-kHz call types, we studied single juvenile rats that were waiting to play with a partner, a situation associated with...

Data from: Duetting behavior varies with sex, season, and singing role in a tropical oriole (Icterus icterus)

Karan J. Odom, David M. Logue, Colin E. Studds, Michelle K. Monroe, Susanna K. Campbell & Kevin E. Omland
Females and males of many animals combine their vocalizations into coordinated acoustic duets. Duets can mediate both cooperation and conflict between partners, and are common in tropical, sedentary species that may use duets for multiple functions year-round. To elucidate the full range of duet functions, we need to study the individual-level behaviors that generate duets throughout the year. We evaluated multiple functions of duetting behavior in female and male Venezuelan troupials (Icterus icterus) during the...

Data from: Parasites and a host's sense of smell: reduced chemosensory performance of fathead minnows (Pimephales promelas) infected with a monogenean parasite

Ebrahim Lari, Cameron P. Goater, David K. Cone & Greg G. Pyle
1. Parasites residing within the central nervous system of their hosts have the potential to reduce various components of host performance, but such effects are rarely evaluated. 2. We assessed the olfactory acuity of fathead minnows (Pimephales promelas) infected experimentally with the monogenean Dactylogyrus olfactorius, the adults of which live within the host's olfactory chambers. 3. Olfactory acuity was compared between infected and uninfected hosts by assessing electro-olfactography (EOG) neural responses to chemical stimuli that...
