Griffon Vultures restrict movements around roosts and supplementary feeding stations, even when carrion is available on the field: a call for wind energy zonation to avoid ecological traps on Mediterranean islands

Wind energy is developing on Mediterranean islands, where endangered populations of Griffon Vulture (Gyps fulvus) occur. As griffons are subjected to collisions with wind turbines while foraging, it is necessary to understand which factors affect their movements, to minimize the potential impact of wind farms. We assessed habitat use by 37 griffons (n. GPS locations = 130,218) and its overlap [...]

The trade-off between vocal learning and dexterity: a balancing act

Pedro Tiago Martins, Cedric Boeckx

Uncontroversial evidence of vocal production learning, the capacity to modify vocal output on the basis of experience, is sparsely distributed in the animal kingdom. We suggest that this is in large part due to a trade-off between vocal learning complexity and a much more widely distributed trait—non-vocal dexterity. We argue that given some generally required neural and anatomical conditions for [...]

The Importance of Representative Sampling for Home Range Estimation in Field Primatology

Understanding the amount of space required by animals to fulfill their biological needs is essential for comprehending their behavior, their ecological role within their community, and for effective conservation planning and resource management. Habituated primates are often studied using handheld GPS data, which provides detailed movement information that can link patterns of ranging and [...]

Repeated evolution of extreme locomotor performance independent of changes in extended phenotype use in spiders

Many animals utilize self-built structures – so-called extended phenotypes – to enhance body functions, such as thermoregulation, prey capture or defence. Yet, it is unclear whether the evolution of animal constructions supplements or substitutes body functions. Here, using Austral brown spiders, we explored if the evolutionary loss and gain of silken webs as extended prey capture devices [...]

Extra-pair paternity, breeding density and synchrony in natural cavities versus nestboxes in two passerine birds

Irene Di Lecce, Charles Perrier, Marta Szulkin, et al.

Most of what is known about extra-pair paternity in hole-nesting birds derives from studies using artificial nesting sites, such as nestboxes. However, it has rarely been investigated whether inference drawn from breeding events taking place in nestboxes matches what would be observed under natural conditions, i.e. in natural cavities. We here report on a variation in promiscuity in blue tits and [...]

What acoustic telemetry can and can’t tell us about fish biology

Acoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably with exciting advances in both hydrophone and transmitter technology. Once a highly specialised methodology however, [...]

Using repeatability of performance within and across contexts to validate measures of behavioral flexibility

Kelsey McCune

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Research into animal cognitive abilities is increasing quickly and often uses methods where behavioral performance on a task is assumed to represent variation in the underlying cognitive trait. However, because these methods rely on behavioral responses as a proxy for cognitive ability, it is important to validate that the task structure does, in fact, target the cognitive trait of interest [...]

Use of Airborne Laser Scanning to assess effects of understorey vegetation structure on nest-site selection and breeding performance in an Australian passerine bird

Published: 2022-12-18

In wild bird populations, the structure of vegetation around nest-sites can influence the risk of predation of dependent offspring, generating selection for nest-sites with vegetation characteristics associated with lower predation rates. However, vegetation structure can be difficult to quantify objectively in the field, which might explain why there remains a general lack of understanding of [...]

Quantifying between-individual variation using high-throughput phenotyping of behavioural traits in the fruit fly (Drosophila melanogaster)

Erin L Macartney, Patrice Pottier, Samantha Burke, et al.

Published: 2022-12-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Behavioural phenotyping is often time and labour-intensive, which can come at a cost to sample size and statistical precision. This is particularly a concern given that behaviours are often highly variable within and between individuals, so naturally requires a larger sample size. Drosophila melanogaster is a common model system in many research fields, and behavioural observations are frequently [...]

Individual identity information persists in learned calls of introduced parrot populations

Grace Smith-Vidaurre, Valeria Perez-Marrufo, Elizabeth A. Hobson, et al.

Published: 2022-09-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Animals can actively encode different types of identity information in learned communication signals, such as group membership or individual identity. The social environments in which animals interact may favor different types of information, but whether identity information conveyed in learned signals is resilient or responsive to social disruption over short evolutionary timescales is not well [...]

Linking Predator Responses to Alkaloid Variability in Poison Frogs

Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Zoology

Many chemically-defended/aposematic species rely on diet for sequestering the toxins with which they defend themselves. This dietary acquisition can lead to variable chemical defenses across space, as the community composition of chemical sources is likely to vary across the range of (an aposematic) species. We characterized the alkaloid content of two populations of the Dyeing Poison Frog [...]

Childhood is a period of life unique to humans. Childhood may have evolved through the need to acquire knowledge and subsistence skills. In an attempt to evaluate the importance of learning for the evolution of childhood, previous research examined the increase with age of returns to foraging across various resources. Any increase could be due to increases in knowledge or other factors such as [...]

Bayesian reinforcement learning models reveal how great-tailed grackles improve their behavioral flexibility in serial reversal learning experiments

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Environments can change suddenly and unpredictably and animals might benefit from being able to flexibly adapt their behavior through learning new associations. Serial (repeated) reversal learning experiments have long been used to investigate differences in behavioral flexibility among individuals and species. In these experiments, individuals initially learn that a reward is associated with a [...]

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Despite the importance of vocalizations in mammalian sociosexual communication, little is known about female preferences for male vocal displays in wild mammals. Here, we characterized female preferences for the advertisement songs of male Alston’s singing mice (Scotinomys teguina). We developed procedures for inducing estrus, using vaginal morphology as a bioindicator. We then broadcasted [...]
