A Systematic Map of Research Exploring the Ecological Modifiers and Consequences of Bark Damaging Behaviour in Squirrel Species
Published: 2022-05-17
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Zoology
Bark-stripping and browsing by mammals in woodlands can cause widespread damage to trees, inhibiting tree growth and leading to whole tree or canopy death. Sciurid species worldwide are known to incorporate inner bark or cambium tissue into their diets, and outer bark can additionally be used as nesting material. The drivers and causes of bark-stripping behaviour have been investigated and [...]
Temporary behavioral responses to playbacks by a pest parrot and implications for management
Published: 2022-04-21
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Human-wildlife interactions continue to increase due to anthropogenic disturbances, with some interactions resulting in conflict. Leveraging a taxa’s bias for a particular sensory cue is a promising management avenue for reducing the potential and realized negative consequences of human-wildlife conflict. For instance, many avian species heavily depend on acoustic communication, and acoustic cues [...]
The evolution of conspicuousness in frogs: when to signal toxicity?
Published: 2022-04-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Many organisms use conspicuous color patterns to advertise their toxicity or unpalatability, a strategy known as aposematism. Despite the recognized benefits of this anti-predator tactic, not all chemically defended species exhibit warning coloration. Here, we use a comparative approach to investigate which factors predict the evolution of conspicuousness in frogs, a group in which conspicuous [...]
Machine learning pipeline extracts biologically significant data automatically from avian monitoring videos
Published: 2022-03-08
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Measuring parental care behaviour in the wild is central to the study of animal life-history trade-offs, but is often labour and time-intensive. More efficient machine learning-based video processing tools have recently emerged that allow parental nest visit rates to be measured using video cameras and computer processing. Here, we used open-source software to detect movement events from videos [...]
Mountain Gorillas benefit from social distancing too: Close proximity from tourists affects gorillas sociality
Published: 2022-02-25
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Gorilla tourism supports the protection of the gorilla ecosystem, benefiting humans and wildlife populations living therein. Assessing to what degree the presence and proximity of tourists affect wildlife aids long-term benefits. Because wild animals might see human activities as stressors, we hypothesised that the increased presence and proximity of tourists leads to an immediate increase in [...]
Intergenerational effects of overfeeding on aversive learning in zebrafish (Danio rerio)
Published: 2022-02-07
Subjects: Animal Experimentation and Research, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences
The obesity epidemic is among the most serious and rapidly growing public health challenges of the 21st century. This rapid increase is concerning as obesity appears to negatively impact cognition and behaviour. Furthermore, some studies suggest that this negative effect could be carried across generations from both mothers and fathers although evidence is not consistent. Here, we attempt to [...]
The effects of an obesogenic diet on behaviour and cognition in zebrafish (Danio rerio): traits average, variability, repeatability, and behavioural syndromes
Published: 2022-02-07
Subjects: Animal Experimentation and Research, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences
The obesity epidemic, largely driven by the accessibility of ultra-processed high-energy foods, is one of the most pressing public health challenges of the 21st century. Consequently, there is increasing concern about the impacts of diet-induced obesity on behaviour and cognition. While research on this matter continues, to date, no study has explicitly investigated the effect of obesogenic diet [...]
How to behave when marooned: the behavioural component of the island syndrome remains underexplored
Published: 2022-01-29
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Animals on islands typically depart from their mainland relatives in assorted aspects of their biology. Because they seem to occur in concert, and to some extent evolve convergently in disparate taxa, these changes are referred to as the “island syndrome”. While morphological, physiological, and life history components of the island syndrome have received considerable attention, much less is [...]
Behavioral flexibility is manipulable and it improves flexibility and innovativeness in a new context
Published: 2022-01-06
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Behavioral flexibility, the ability to adapt behavior to new circumstances, is thought to play an important role in a species' ability to successfully adapt to new environments and expand its geographic range. However, flexibility is rarely directly tested in a way that would allow us to determine how flexibility works to predict a species' ability to adapt their behavior to new environments. We [...]
Ecogeography of group size suggests differences in drivers of sociality among cooperatively breeding fairywrens
Published: 2022-01-06
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences
Cooperatively breeding species exhibit a range of social behaviors associated with different costs and benefits to group-living, often in association with different environmental conditions. For example, species in which collective-care of offspring reduces the cost of reproduction are more common in harsh environments (true cooperative breeding), while species that collectively defend resources [...]
Temporal patterns in prey size between sexes in a raptor with extreme size dimorphism: testing the intersexual competition hypothesis using web-sourced photographs
Published: 2021-11-28
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Ornithology, Zoology
In most vertebrates, males are larger than females. For raptors, sexual size dimorphism is reversed, with females being larger. Reversed sexual dimorphism (RSD) in raptors is strongly linked to diet, with species feeding on the most agile prey, for example bird-eating raptors, showing the greatest size differences between the sexes. Hypotheses for reversed sexual dimorphism (RSD) include the [...]
Take only pictures, leave only… Cameras influence marmot vigilance but not perceptions of risk
Published: 2021-11-21
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Ecotourism promotes conservation efforts while also allowing for low impact observation of wildlife. Many ecotourists photograph wildlife and photography plays an important role in focusing the public’s attention on nature. Although photography is commonly believed to be a low impact activity, how the visual stimulus of a camera influences wildlife remains unknown. Since animals are known to fear [...]
The better, the choosier: a meta-analysis on inter-individual variation of male mate choice
Published: 2021-11-17
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Male mate choice occurs in several animal species, but we know little about the factors that influence the expression of this behaviour. Males vary in their capacity to acquire mates (i.e. male quality), which could be crucial to male mate choice expression but it is often overlooked. Using a meta-analytical approach, we explore inter-individual variation in the expression of male mate choice by [...]
Thermal plasticity in behavioural traits mediates mating and reproductive dynamics in an ectotherm
Published: 2021-11-08
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Global changes in temperature potentially influence sexual selection by restricting opportunities for activity. However, explicit tests of the behavioural mechanisms linking thermal variation to mating and reproductive performance are rare. We address this gap in a temperate lizard by combining social network analysis with molecular pedigree reconstruction in a large-scale thermal manipulation [...]
Mobbing in animals: a thorough review and proposed future directions
Published: 2021-10-26
Subjects: Animal Sciences, Animal Studies, Behavior and Ethology, Biology, Communication, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
Mobbing is an important anti-predator behavior where prey harass and attack a predator to lower the immediate and long-term risk posed by predators, warn others, and communicate about the predator’s threat. While this behavior has been of interest to humans since antiquity, and aspects of it have been well researched for the past 50 years, we still know little about its ecology and the [...]
