From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

A Bimodal Extension of the Beta-Binomial Distribution with Applications

Axioms
In this paper, we propose an alternative distribution to model count data exhibiting uni/bimodality. It arises as a weighted version of the beta-binomial distribution, which is defined by a parametric weight function that admits up to two modes for the ...

A 4D geometric morphometrics workflow to quantify complex biological motion

Methods in Ecology and Evolution, EarlyView.
Abstract Quantifying biological motion is fundamentally tied to quantifying the biological structures that produce that motion. Yet, this dependence makes it essential to decouple motion from static morphology to enable general, comparable analyses across individuals and conditions. In this work, we present a methodological pipeline to study biological

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.
