Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

open access: yesConservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Estimating the total mortality of seabirds following a marine heat wave

open access: yesConservation 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.

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

open access: yesConservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Subsistence hunting shapes the spatial variation of jaguar densities in community‐managed forests

open access: yesJournal of Zoology, EarlyView.
Jaguars and people can coexist in community‐managed forests, but distance matters. In Guatemala's Maya Biosphere Reserve, jaguar numbers increased markedly in areas harder to reach on foot, yet jaguars were still found near communities, showing that responsibly managed forests can support jaguar populations while allowing people to maintain traditional

Estimating the Stature of an Ancient North Andean Population From Articular Breadths and Diaphyseal Diameters: An Extension of Anzellini and Toyne (2020) Aproximando la Estatura de Poblaciones Norandinas Antiguas Utilizando Medidas de lo Ancho de Articulaciones y Los Diámetros de la Diáfisis: Una Extension de Anzellini y Toyne (2020)

open access: yesAmerican Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.
ABSTRACT Stature estimation of skeletal remains is mostly dependent on the lengths of long bones, but these are often unavailable in fragmented or commingled assemblages. To overcome this obstacle, we present an extension of the unisex stature estimation models for high‐altitude Andean populations presented by Anzellini and Toyne (2020) using femoral ...

An integrated approach to balance freshwater connectivity restoration and invasion risk

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...
