Persecuted mammals as indicators of moderate human disturbance in the Peruvian Amazon

Frontiers in Conservation Science
Human population growth, land conversion, and hunting are accelerating defaunation in tropical forests. We asked how anthropogenic and ecological factors shape the site use (occupancy) of medium- to large-bodied mammals in an unprotected Amazonian ...

Optimizing DNA extraction protocols for bryophytes: Insights from Orthotrichaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Extracting high‐quality DNA from challenging plant tissues can be hindered by high levels of phenolics, carbohydrates, and other compounds that bind to or coprecipitate with DNA. Bryophytes, due to their small size, tendency to intermix, biochemical richness, and capacity to absorb environmental pollutants and heavy metals, pose unique

Serial section videography (SSV): A low‐cost protocol for generating 3D reconstructions of internal plant structure

Applications in Plant Sciences, EarlyView.
Abstract Premise Analyzing structural changes along the length of an organ provides insight into its development. However, traditional histological methods are limited by intensive procedures and size restrictions. Micro‐computed tomography (microCT) enables non‐destructive internal imaging along the length of an organ, but high cost, technical ...

PlantSAM: An object detection‐driven segmentation pipeline for herbarium specimens

Applications in Plant Sciences, EarlyView.
Abstract Premise Deep learning–based classification of herbarium images is hampered by background heterogeneity, which introduces noise and artifacts that can potentially mislead models and degrade their accuracy. Addressing these effects is essential to enhance overall performance. Methods We introduce PlantSAM, an automated segmentation pipeline that

Evaluating the quality and educational utility of YouTube videos in teaching human surface anatomy

Anatomical Sciences Education, EarlyView.
Abstract YouTube is increasingly used by medical and health science students as a supplementary learning tool. However, the quality and educational value of surface anatomy videos on YouTube remain underexplored. This study aimed to systematically evaluate the quality, reliability, and educational usefulness of YouTube videos focusing on human surface ...

Understanding preferences for nature's contributions to people between and within social actors sheds insights for inclusive conservation

People and Nature, EarlyView.
Abstract Despite calls for wider inclusion of diverse actors in conservation management, researchers tend to lump actors together into one group, potentially overlooking heterogeneity within the groups themselves—in turn, hampering inclusiveness. The risk of stereotyping social actors and oversimplifying their differentiated preferences for Nature's ...

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

PLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.
