Sex-specific discrimination of familiar and unfamiliar mates in the Tokay gecko

Marie-Ornelia Verger, Maëlle Devillebichot, Eva Ringler, et al.

Social animals need to keep track of other individuals in their group to be able to adjust their behaviour accordingly and facilitate group cohesion. This recognition ability varies across species and is influenced by cognitive capacities such as learning and memory. In reptiles, particularly Squamates (lizards, snakes, and worm lizards), pheromonal communication is pivotal for territoriality, [...]

The relative contribution of acoustic signals versus movement cues in group coordination and collective decision-making

Chun-Chieh Liao, Robert D. Magrath, Marta B Manser, et al.

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

To benefit from group living, individuals need to maintain cohesion and coordinate their activities. Effective communication thus becomes critical, facilitating rapid coordination of behaviours and reducing consensus costs when group members have differing needs and information. In many bird and mammal species, collective decisions rely on acoustic signals in some contexts but on movement cues in [...]

Puma space use and dispersal in tropical biodiversity hotspots: bridging a gap to connect individuals to populations

Bernardo Brandão Niebuhr, Sandra Maria Cintra Cavalcanti, Ermeson A. Vilalba, et al.

Published: 2024-01-25
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Zoology

Assessing residency and dispersal behavior of apex predators and its consequences for landscape connectivity is of paramount importance for understanding population- and ecosystem- effects of anthropogenic land use change. However, basic information on animal space use is still lacking, particularly in the Tropics. Here we synthesize ranging and dispersal ecological information on pumas (Puma [...]

No time to die: Temporal patterns of nest predation in a multi-brooded Southern Hemisphere passerine bird

Richard S. Turner, Helen L. Osmond, Robert D. Magrath, et al.

Published: 2024-01-18
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Ornithology

1. Nest predation is frequently the primary cause of early-life mortality in wild avian populations, generating selection for optimising the timing of reproduction to reduce predation risk. Investigating temporal patterns of nest predation is therefore necessary for understanding the intricate relationships between birds and their predators. 2. In this study, we considered the role of temporal [...]

Incubation behaviour of a boreal, food-caching passerine nesting in sub-zero temperatures

Joseph Burant, Roxan Chicalo, Emily J Williams, et al.

Published: 2024-01-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology

Our understanding of avian incubation behaviour is primarily derived from species that nest in the temperate conditions of spring and summer. This leaves uncertainties about strategies employed by a relatively small number of species adapted to breed under sub-zero, winter-like conditions. We used in-nest temperature loggers (iButtons) to monitor incubation behaviours of Canada Jays, [...]

Animal social networks are robust to changing association definitions

Alex Hoi Hang Chan, Jamie Dunning, Terry Burke, et al.

Published: 2024-01-12
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Ornithology

The interconnecting links (edges) between individuals (nodes) in an animal social network are often defined by discrete, directed behaviours (interactions). However, where interactions are difficult to observe, a network edge is instead defined as individuals sharing space or overlapping in time (an association). Despite an increasingly accessible toolkit to assemble and analyse animal social [...]

Vocal Dimorphism in Anna’s Hummingbirds

Whereas vocal sexual dimorphism is widespread amongst birds, it has been historically overlooked in non-passerines such as hummingbirds. By evaluating correlations among sex, behaviors, and vocalizations, the meaning and utility of intentional sound production may be inferred. Anna's Hummingbirds (Calypte anna) exhibit pronounced sexual dimorphism, with males being larger and having more vibrant [...]

Covariance reaction norms: A flexible approach to estimating continuous environmental effects on quantitative genetic and phenotypic (co)variances

Jordan Scott Martin

Published: 2023-11-21
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Genetics, Integrative Biology, Life Sciences, Population Biology, Research Methods in Life Sciences, Zoology

Estimating quantitative genetic and phenotypic (co)variances plays a crucial role in investigating key evolutionary ecological phenomena, such as developmental integration, life history tradeoffs, and niche specialization, as well as in describing selection and predicting multivariate evolution in the wild. While most studies assume (co)variances are fixed over short timescales, environmental [...]

Sex-specific associations between social behaviour, its predictability and fitness in a wild lizard

Barbara Agathe Class, Kasha Strickland, Dominique Potvin, et al.

Published: 2023-11-21
Subjects: Behavior and Ethology

Social environments impose a number of constraints on individuals’ behaviour. These constraints have been hypothesized to generate behavioural variation among individuals, social responsiveness, and within-individual behavioural consistency (also termed ‘predictability’). In particular, the social niche hypothesis posits that higher levels of competition associated with higher population density [...]

Automated tracking of avian parental care behavior

Grace Smith-Vidaurre, Tania Molina, Erich D. Jarvis, et al.

Published: 2023-11-16
Subjects: Behavior and Ethology, Biology, Life Sciences

1. Parental care may be an important source of phenotypic variation for ecological and evolutionary processes. However, it can be difficult to collect and interpret data on parental care behaviors. To address these challenges, we developed a new hardware and software platform for automated behavioral tracking called ABISSMAL (Automated Behavioral Tracking by Integrating Sensors that Survey [...]

Darwin’s road not taken: white sclera, shared intentionality, niche construction, predator fear, teams and Homo origins

John Robert Skoyles

Published: 2023-11-04
Subjects: Behavior and Ethology, Evolution, Neuroscience and Neurobiology

Palaeoanthropologists have yet to pinpoint how Homo evolved from Australopithecus. I propose niche construction ending predator ambush and stalking attacks, white sclera, and ultrafast team cognition were key. Human white sclera allows the quick, distant detection of line-of-sight. This is unique. In other primates, predators eliminate conspicuous-eyed individuals. Consequently, nonhuman [...]

Maternal investment and early thermal conditions affect performance and antipredator responses

Maider Iglesias Carrasco, Jiayu Zhang, Daniel W.A. Noble

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

Christina Hansen Wheat, Clive DL Wynne

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 [...]
