Maternal investment and early thermal conditions affect performance and antipredator responses
Published: 2023-10-27
Subjects: Behavior and Ethology, Biology, Evolution, Other Ecology and Evolutionary Biology
Exposure to increased temperatures during early development can lead to phenotypic plasticity in morphology, physiology, and behaviour across a range of ectothermic animals. In addition, maternal effects are known to be important contributors to phenotypic variation in offspring. Whether the two factors interact to shape offspring morphology and behaviour has been barely explored. This is [...]

The unfulfilled potential of dogs in studying behavioural evolution during the Anthropocene
Published: 2023-08-07
Subjects: Behavior and Ethology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Zoology
Dogs are an exceptional resource for studying ecological, behavioural and evolutionary processes, but remain under-represented within these fields due to the anthropomorphisation of dog behaviour, and the view that dog domestication was human-driven. These widespread misconceptions limit our understanding of dog behaviour and inhibit the use of dogs as study systems in diverse areas of biological [...]
The Puzzle of Leadership: The Interplay between Individual Traits and Coordination Mechanisms
Published: 2023-08-07
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In social systems, movement of individual group members scales up to spatiotemporal dynamics of the group. However, the level of influence on group movement dynamics can be variable among group members. The influence of an individual is often referred to as their leadership potential. However, despite the common occurrence of leader-follower patterns across various taxa, little is known whether [...]
Recent human-bear conflicts in Northern Italy: a review, with considerations of future perspectives
Published: 2023-07-17
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Zoology
The killing of a runner in Northern Italy by a brown bear (Ursus arctos arctos) and the subsequent investigation of such matter highlighted a Human-Wildlife Conflict (HWC) that has been present in Trentino since the introduction of bears for conservation during the Life Ursus Project. Such conflict may be exacerbated as both human and bear populations get bigger. In this paper, I summarize the [...]
Camtrap DP: An open standard for the FAIR exchange and archiving of camera trap data
Published: 2023-06-30
Subjects: Behavior and Ethology, Biodiversity, Population Biology
Camera trapping has revolutionized wildlife ecology and conservation by providing automated data acquisition, leading to the accumulation of massive amounts of camera trap data worldwide. Although management and processing of camera trap-derived Big Data are becoming increasingly solvable with the help of scalable cyber-infrastructures, harmonization and exchange of the data remain limited, [...]
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
Published: 2023-06-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Environmental Engineering
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
Published: 2023-05-30
Subjects: Animal Sciences, Behavior and Ethology, Behavioral Neurobiology, Cognitive Neuroscience, Ecology and Evolutionary Biology, Life Sciences
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
Published: 2023-05-04
Subjects: Behavior and Ethology, Other Ecology and Evolutionary Biology
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
Published: 2023-04-24
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences, Zoology
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
Published: 2023-02-17
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Ornithology
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
Published: 2023-02-07
Subjects: Animal Sciences, Aquaculture and Fisheries Life Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Zoology
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
Published: 2023-01-31
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
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Ornithology
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)
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 [...]
