Lateralized brain function, or partitioning of tasks to separate hemispheres of the brain, directly impacts behaviour and fitness. Highly lateralized individuals tend to outperform nonlateralized individuals in many survival-related behaviours, such as the ability to learn, escape predators and multitask. Despite these benefits to lateralization, there is a great deal of observed variation in this trait within and between populations that is likely determined by the balance between costs and benefits of laterality in a given environment. Laterality appears to be heritable, but it can also vary with the environment experienced during development. We investigated the role of evolutionary history and developmental plasticity in determining the degree of laterality in the Trinidadian guppy, Poecilia reticulata, a freshwater fish that experiences variable predation pressure in its native range. We compared pairs of closely related populations that experience either high or low levels of predation in the wild, and manipulated the perceived predation risk in the rearing environment using a common garden split-brood design. We assayed laterality in mature male guppies using a detour test. Fish reared with exposure to chemical predator cues were more lateralized than their brothers reared without predator cues. This plastic response is in the direction we would predict if lateralization is favoured in environments with high predation risk. However, unlike findings in related species, we did not detect repeatable differences in degree of laterality associated with historical predation regime, suggesting that predation risk experienced over evolutionary history does not shape laterality patterns in guppies. Thus, although it is currently underemphasized in the literature, plasticity is likely an important contributor to variation in laterality. (C) 2014 The Association for the Study of Animal Behaviour.

Diel patterns of movement reveal temporal strategies during dispersal

James A. Klarevas-Irby, Damien R. Farine

Summary: Little is known about how animals overcome temporal constraints on movement during dispersal. This study used GPS tracking of vulturine guineafowl and found that dispersers showed the greatest increase in movement at the same times of day when they moved the most prior to dispersal. These findings suggest that individuals face the same ecological constraints during dispersal as they do in daily life and achieve large displacements by maximizing movement when conditions are most favorable.

Ritual displays by a parasitic cuckoo: nuptial gifts or territorial warnings?

Simone Ciaralli, Martina Esposito, Stefano Francesconi, Daniela Muzzicato, Marco Gamba, Matteo Dal Zotto, Daniela Campobello

Summary: Male cuckoos may transfer nest location information to females as a nonmaterial nuptial gift through specific postures and behaviors, potentially influencing mating choices of female cuckoos.

Quantifying mating behaviour using accelerometry and machine learning: challenges and opportunities

Anne E. Aulsebrook, Rowan Jacques-Hamilton, Bart Kempenaers

Summary: Accelerometry and machine learning have been used to quantify mating behaviors of captive male ruffs. Different machine learning methods were compared and evaluated for their classification performance. The study highlights the challenges and potential pitfalls in classifying mating behaviors using accelerometry and provides recommendations and considerations for future research.

Workload inequality increases with group size in a cooperatively breeding bird

Maria G. Smith, Joshua B. LaPergola, Christina Riehl

Summary: This study analyzed individual contributions to parental care in the greater ani bird and found that workload inequality varied between groups of two and three pairs. However, there was no clear evidence of division of labour within the groups, suggesting individual differences in overall work performed.

Winner and loser effects in humans: evidence from randomized trials

Noah M. T. Smith, Reuven Dukas

Summary: Winner and loser effects are observed in many animals, and recent experiments suggest that they may also occur in humans. In two experiments involving video games and reading comprehension, participants who won in the first phase performed significantly better in the second phase compared to those who lost. The effect size was larger in the video game experiment, and men and women showed similar magnitudes of winner and loser effects.

Too hot to handle: male dragonflies decrease time spent mating at higher temperatures

Bianca J. L. Marcellino, Peri Yee, Shannon J. Mccauley, Rosalind L. Murray

Summary: This study examines the trade-off between mating effort and thermoregulatory behavior in dragonflies in response to temperature changes, and investigates the effect of wing melanin on these behaviors. The results indicate that as temperature increases, dragonflies reduce their mating effort and increase their thermoregulatory behavior.

Unrevealing components of risk assessment: escape behaviour and refuge use in a web-building spider

Rafael Rios Moura, Paulo Inacio Prado, Joao Vasconcellos-Neto

Summary: This study examined the escape behavior and decision-making of Aglaoctenus castaneus spiders on different substrates. It was found that spiders inhabiting injurious substrates displayed shorter flight initiation distances and lower sensitivity to predators.

African penguins utilize their ventral dot patterns for individual recognition

Luigi Baciadonna, Cwyn Solvi, Francesca Terranova, Camilla Godi, Cristina Pilenga, Livio Favaro

Summary: In this study, it was found that African penguins could use ventral dot patterns to recognize their lifelong partner and nonpartner colonymates. This challenges the previous assumption of limited visual involvement in penguin communication, highlighting the complex and flexible recognition process in birds.

Rise and fall: increasing temperatures have nonlinear effects on aggression in a tropical fish

Nick A. R. Jones, Jade Newton-Youens, Joachim G. Frommen

Summary: Environmental conditions, particularly temperature, have a significant impact on animal behavior. This study focused on aggression in Neolamprologus pulcher fish and found that aggression rates increased with temperature at lower levels, but decreased after reaching a peak. Additionally, the influence of high temperatures on aggression changed over time during the trials. These findings provide a more comprehensive understanding of the short-term effects of temperature on aggression and highlight the importance of considering non-linear changes in thermal performance.

Age mediates access to landfill food resources and foraging proficiency in a long-lived bird species

Bruno Herlander Martins, Andrea Soriano-Redondo, Aldina M. A. Franco, Ines Carry

Summary: Human activities have affected the availability of resources for wildlife, particularly through the provision of anthropogenic food subsidies at landfill sites. This study explores the influence of age on landfill attendance and foraging behavior in white storks. Adult storks visit landfills more frequently and show dominance over juveniles in food acquisition. Juveniles have limited access to landfill resources and are forced to use lower quality areas.
