The search behavior of terrestrial mammals Open
Summary Animals moving through landscapes need to strike a balance between finding sufficient resources to grow and reproduce while minimizing encounters with predators 1,2 . Because encounter rates are determined by the average distance o…

Clarifying space use concepts in ecology: range vs. occurrence distributions Open
Quantifying animal movements is necessary for answering a wide array of research questions in ecology and conservation biology. Consequently, ecologists have made considerable efforts to identify the best way to estimate an animal’s home r…

Evaluating expert‐based habitat suitability information of terrestrial mammals with <span>GPS‐</span>tracking data Open
Aim Macroecological studies that require habitat suitability data for many species often derive this information from expert opinion. However, expert‐based information is inherently subjective and thus prone to errors. The increasing avail…

SNAPSHOT USA 2019: a coordinated national camera trap survey of the United States Open
With the accelerating pace of global change, it is imperative that we obtain rapid inventories of the status and distribution of wildlife for ecological inferences and conservation planning. To address this challenge, we launched the SNAPS…

Ecological insights from three decades of animal movement tracking across a changing Arctic Open
Ecological “big data” Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in the Arctic, yet this region remains one of the most remote and difficult to study. Researchers have increasingly …

A comprehensive framework for handling location error in animal tracking data Open
Animal tracking data are being collected more frequently, in greater detail, and on smaller taxa than ever before. These data hold the promise to increase the relevance of animal movement for understanding ecological processes, but this po…

Effects of body size on estimation of mammalian area requirements Open
Accurately quantifying species’ area requirements is a prerequisite for effective area‐based conservation. This typically involves collecting tracking data on species of interest and then conducting home‐range analyses. Problematically, au…

Right on track? Performance of satellite telemetry in terrestrial wildlife research Open
Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite …

A comprehensive analysis of autocorrelation and bias in home range estimation Open
Home range estimation is routine practice in ecological research. While advances in animal tracking technology have increased our capacity to collect data to support home range analysis, these same advances have also resulted in increasing…

Integrating snow science and wildlife ecology in Arctic-boreal North America Open
Snow covers Arctic and boreal regions (ABRs) for approximately 9 months of the year, thus snowscapes dominate the form and function of tundra and boreal ecosystems. In recent decades, Arctic warming has changed the snowcover's spatial exte…

Moving in the Anthropocene: Global reductions in terrestrial mammalian movements Open
Restrictions on roaming Until the past century or so, the movement of wild animals was relatively unrestricted, and their travels contributed substantially to ecological processes. As humans have increasingly altered natural habitats, natu…

Profound seasonal shrinking and regrowth of the ossified braincase in phylogenetically distant mammals with similar life histories Open
Ontogenetic changes in skull shape and size are ubiquitous in altricial vertebrates, but typically unidirectional and minimal in full-grown animals. Red-toothed shrews exhibit a rare exception, where the shape, mass and size of the skull, …

Code S1. from Growth overshoot and seasonal size changes in the skulls of two weasel species Open
Program R code for executing bootstrapping of t-tests to compare skull metrics between age, sex, species, and origin groupings.

Cognitive skills of common shrews (<i>Sorex araneus</i>) vary with seasonal changes in skull size and brain mass Open
In a rare phenomenon, shrews and few other species cope with seasonal environments by reducing and regrowing brain size, potentially at the cost of changes in cognitive abilities. Here, we confirm an extensive, seasonal shrinkage (21.4%) a…

Growth overshoot and seasonal size changes in the skulls of two weasel species Open
Ontogenetic changes in mammalian skulls are complex. For a very few species (i.e. some Sorex shrews), these also include seasonally driven, bidirectional size changes within individuals, presumably to reduce energy requirements during low …
