Abstract Estimating the abundance or density of wildlife populations is a critical part of species conservation and management, but estimates can vary greatly in precision and accuracy according to the sampling and statistical methods, sampling and e

Understanding how human activities are altering landscapes is critical to address habitat loss and biodiversity decline. Cumulative pressure mapping has emerged as a tool to quantify both the extent and intensity of multiple forms of human activities

Abstract Conservation strategies for imperiled species are frequently based on identifying and addressing the probable causes of population decline, an approach known as the declining population paradigm. Causes, however, are frequently linked to dem

The influence of human pressure within the matrix surrounding habitat fragments remains poorly understood. This study measures the relationship between habitat fragmentation, matrix condition and the change in extinction risk of 4,426 terrestrial mam

Efforts are underway in Canada to set aside terrestrial lands for conservation, thereby protecting them from anthropogenic pressures. Here we produce the first Canadian human footprint map by combining 12 different anthropogenic pressures and identif

Abstract Lethal population control has a history of application to wildlife management and conservation. There is debate about the efficacy of the practice, but more controversial is the ethical justification and methods of killing one species in fav

Media coverage of traffic crashes involving people walking and bicycling tends to frame crashes as isolated events rather than as a public health problem that disproportionately affects vulnerable populations. This study assessed public health framin

Abstract The boreal forest is the largest intact forest in the world, and a refuge for species experiencing range retractions as a consequence of climate and landscape change. Yet, large tracts of the boreal forest are threatened by the cumulative im

Abstract As the defining force of the Anthropocene, human enterprise is reshaping Earth's surface and climate. As part of that process, growth‐inducing infrastructure, such as electrical transmission lines, export facilities, and roads, presents no

Abstract Inter‐individual variability in behavior has been studied extensively for a wide range of species. However, few researchers have considered marginality, defined as the degree to which a choice made by an individual is located at the margin
