Heritability and maternal effects on social attention during an attention bias task in a non-human primate, Macaca mulatta

Social attention is fundamental to a wide range of behaviours in non-human primates. However, we know very little about the heritability of social attention in non-human primates, and the heritability of attention to social threat has not been assessed. Here, we provide data to begin to fill this gap in knowledge. We tested 67 female rhesus macaques, Macaca mulatta, on an attention bias [...]
A protocol for using drones to assist monitoring of large breeding bird colonies

Drones are rapidly becoming part of environmental monitoring and management applications. They provide an opportunity to improve a number of activities related to monitoring population dynamics of aggregations of wildlife. Bird surveys using drones have attracted particular attention, with a range of potential metrics able to be derived from high resolution drone imagery. Whilst a number of [...]
A continental measure of urbanness predicts avian response to local urbanization

Understanding species-specific relationships with their environment is essential for ecology, biogeography, and conservation biology. Moreover, understanding how these relationships change with spatial scale is critical to mitigating potential threats to biodiversity. But methods which measure inter-specific variation in responses to environmental parameters, generalizable across multiple spatial [...]
Seeing rare birds where there are none: self-rated expertise predicts correct species identification, but also more false rarities
Published: 2019-02-04
Subjects: Animal Sciences, Biodiversity, Life Sciences, Ornithology
The use of crowdsourced data is growing rapidly, particularly in ornithology. Citizen science greatly contributes to our knowledge, however, little is known about the reliability of data collected in that way. We found, using an online picture quiz, that self-proclaimed expert birders were more likely to misidentify common British bird species as exotic or rare species, compared to people who [...]
BEHAVIOUR OF WHITE FULANI CALVES GRAZING PANICUM/STYLO PASTURE IN SOUTHWEST NIGERIA
Published: 2019-01-02
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
The objective of this study was to investigate the behaviour of White Fulani (WF) yearling calves grazing a Panicum maximum/Stylosanthes guainensis mixture under traditional management system in south western Nigeria. The effects of two biomass spatial distribution (dense and sparse) were evaluated in association with three pasture heights (10, 15 and 20 cm), with calves allowed access to the [...]
Monitoring large and complex wildlife aggregations with drones

• Recent advances in drone technology have rapidly led to their use for monitoring and managing wildlife populations but a broad and generalised framework for their application to complex wildlife aggregations is still lacking • We present a generalised semi-automated approach where machine learning can map targets of interest in drone imagery, supported by predictive modelling for estimating [...]
Timber harvest and tree size near nests explains variation in nest site occupancy but not productivity in northern goshawks (Accipiter gentilis)
Published: 2018-12-09
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Ornithology
Conservation concern for the northern goshawk (Accipiter gentilis) reflects evidence that goshawks may abandon nest sites or suffer from reduced nesting success in response to some forms of timber harvest. However, this evidence is mixed and has yet to be reviewed systemically and quantitatively. Therefore, we conducted a meta-analysis to assess the extent to which timber harvest and tree size [...]
Female Maylandia zebra prefer victorious males

Females of a widespread species of the rock‐dwelling haplochromine cichlids of Lake Malawi, Maylandia zebra, show preference for males that successfully evict intruding males from their territory. This behaviour, experimentally induced by the investigators in a laboratory setting, was also preferred over males that were not permitted to interact with any other individual.
