Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...

Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

The association between oral health clusters and oral health‐related quality of life: A population‑based study of 5‑yr‑old children

European Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract This study aimed to describe oral health clusters that combine dental conditions and perceived oral health and to examine the association of oral health indicators and their clusters with oral health‐related quality of life (OHRQoL) in 5‐yr‐old children.

Re‐Evaluating Inherited SIF Anomaly Detection Methods for the 2024 Amazon Drought: A 3D Convolutional Autoencoder Approach

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract In the past decade, the Amazon has experienced multiple severe droughts, raising critical questions about how vegetation stress can be detected using remote sensing indicators such as Solar‐Induced Chlorophyll Fluorescence (SIF). In this study, we compare two anomaly detection approaches applied to TROPOSIF data. First a classical pixel wise z‐
