Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

open access: yesThe Anatomical Record, Volume 308, Issue 12, Page 3082-3104, December 2025.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.

Genomic Signatures in Maned Three‐Toed Sloths From Ancient to Recent Environmental Changes in Brazil's Threatened Atlantic Forest

open access: yesMolecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Environmental and climatic changes have shaped the evolutionary trajectories of natural populations, leaving genomic signatures that reflect how species respond to these shifts and their impacts on genetic health. While these insights are essential for unravelling evolutionary histories and informing conservation strategies, studies on ...

Making vertebrate fossil radiocarbon dates more useful for global scientific research

open access: yesJournal of Quaternary Science, Volume 40, Issue 8, Page 1309-1335, November 2025.
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Reservorios mamíferos del Trypanosoma cruzi en Paraguay

open access: yesMemorias del Instituto de Investigaciones en Ciencias de la Salud, 2013
La transmisión enzoótica del Trypanosoma cruzi en Paraguay aún no ha sido bien determinada. Por lo tanto, todavía se desconocen varios aspectos de la dinámica de transmisión de este parásito en el medio selvático, como ser especies de reservorios ...

Social media videos highlight the impacts of the illegal use of snares on Brazilian biodiversity

open access: yesPeople and Nature, Volume 7, Issue 11, Page 2811-2820, November 2025.
Abstract Snares are one of the most used types of non‐selective traps for hunting worldwide, though their use is prohibited in many countries, including Brazil. Indiscriminate and unmonitored use of snares can induce serious conservation problems, particularly in megadiverse countries where higher species richness and diversity mean that the ...

El tipo scratch-digger en dos armadillos (Dasypodidae, Xenarthra): ontogenia esqueletaria de las manos y variaciones de dígitos

open access: yesRevista del Museo de La Plata, 2017
Los estudios comparativos y ontogenéticos referidos al esqueleto de las manos de los armadillos (Dasypodidae, Xenarthra), son escasos. En este trabajo se caracterizan los autopodios anteriores adultos en dos especies de armadillos actuales, Dasypus ...

Pixelated pathologies: Camera trapping as a tool for monitoring wildlife health

open access: yesJournal of Applied Ecology, Volume 62, Issue 11, Page 2894-2913, November 2025.
Given the increasing emergence of diseases, some with conservation and public health implications, improving and expanding wildlife health surveillance strategies is imperative. Camera trapping is particularly relevant for detecting new outbreaks, monitoring high‐risk zones and evaluating risk mitigation measures. Abstract Camera trapping has become an

Direct comparison of herpetofaunal camera, pitfall, and funnel trapping in the upland habitats of Florida, USA

open access: yesWildlife Society Bulletin, Volume 49, Issue 3, September 2025.
Herpetofaunal camera arrays versus pitfall and funnel trap arrays were tested in upland habitats of Florida, USA, and found that the methods are complementary in recording species richness and abundance; they were also similar in costs of use. Future herpetofaunal field studies should employ both cameras and live traps to best estimate populations and ...
