In areas where animals exist in close proximity to humans, some species change their spatial and temporal activity patterns to reduce their chances of encountering humans. Changes in the temporal activity of a species may affect diverse aspects of the species behavior and its physiology. Behavioral patterns are expected to respond to changes in environmental conditions before changes in the size of the population occur, and monitoring these will allow early human influences on wildlife to be identified. Understanding the effect of human settlements on the diurnal activities of mammals is important as a knowledge-base for management decision-marking, with the aim of preserving species and the ecosystems they inhabit. The research goal is to quantify the influence of human settlements on the temporal activity patterns of medium and large mammals.

]]> Few previous studies on the factors that affect Striped Hyaena (Hyaena hyaena
Linnaeus, 1758) occurrence and densities were done on geographically unrelated populations
using different methodologies. In Israel, hyaenas occur throughout the country’s
steep climatic and geographical gradients, presenting a unique opportunity to
study densities and habitat use across adjacent ecosystems using a unified methodology
and test previous conceptions regarding the species’ habitat selection. We collected
hyaena abundance-absence data using 1440 camera traps placed at 80 sites (2012–
2016). Site location ranged from hyper-arid deserts to dense Mediterranean shrubland.
We assessed the effect of climate, habitat structure, elevation, geomorphological attributes
(proxy for den availability), and anthropogenic development (proximity to settlements
and agriculture) on hyaena densities using N-mixture models. Hyaena densities
were negatively affected by anthropogenic development, and were limited by den
availability. Hyaena densities did not follow a climatic or geographic gradient. Densities
were highest at hyper-arid deserts and Mediterranean coastal shrublands. Despite
the former conception that hyaenas prefer semi-arid open habitats and avoid extreme
deserts and dense vegetation, we show that hyaenas use and even thrive in these habitats
when geomorphological conditions are suitable and resources are available.
