The use of small Unmanned Aircraft Systems (UAS; also known as “drones”) for professional
and personal-leisure use is increasing enormously. UAS operate at low altitudes (< 500 m) …

Acuity, the fineness with which sensory systems perceive and parse information, limits the
information that organisms can extract from stimuli. Here, we focus on visual acuity (the …

Environmental temperature has systematic effects on rates of species interactions, primarily
through its influence on organismal physiology. We present a mechanistic model for the …

Given the marked variation in abiotic and biotic conditions between day and night, many
species specialise their physical activity to being diurnal or nocturnal, and it was long …

Space used by animals increases with increasing body size. Energy requirements alone can
explain how population density decreases, but not the steep rate at which home range area …

It has long been suggested that tropical species are generally more colourful than temperate
species, but whether latitudinal gradients in organismal colourfulness exist remains …

Current hypotheses that use visually guided reaching and grasping to explain orbital
convergence, visual specialization, and brain expansion in primates are open to question …

Face perception serves as the basis for much of human social exchange. Diverse
information can be extracted about an individual from a single glance at their face, including …

Outdoor recreation is increasing in intensity and space. Areas previously inaccessible are
now being visited by ever‐growing numbers of people, which increases human–wildlife …

Among extant vertebrates, only the 23 species of vulture are obligate scavengers. We use
an energetic modelling approach to explore the constraints imposed by an obligate …
