Conservation Biology, Volume 40, Issue 4, August 2026.
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.

Improving the use of expert opinion in disease risk analysis for conservation translocations

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Conservation translocations are subject to considerable uncertainty and risk, of which disease is one of the most recognized. To address disease risks, several protocols for qualitative disease risk analysis (qDRA) exist and are used for responsible conservation translocation planning.

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)

American 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 ...

MODELO TEÓRICO PARA LA ESTIMACIÓN DE LA DENSIDAD RADICULAR DE DOS ESPECIES LEÑOSAS

Tropical and Subtropical Agroecosystems, 2009
Los estudios de raíces en especies leñosas son de gran importancia ya que con ellos se puede predecir o modelar el crecimiento vegetal bajo diferentes esquemas de manejo y/o condiciones ambientales. Sin embargo, la metodología para calcular la densidad radicular (Lv) es laboriosa y consume mucho tiempo. Un método alternativo y rápido se basa en el
