Effects of landscape fragmentation on floodplain fishes as revealed by species-habitat networks. [PDF]

Conserv Biol
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Forest Guardians: The Role of Dense Forests and Water Networks in Supporting Lowland Tapir (<i>Tapirus terrestris</i>) Populations in the Orinoquia Region of Colombia. [PDF]

Ecol Evol
Our study reveals that lowland tapir (Tapirus terrestris ) occupancy in Colombia's Orinoquia region is strongly influenced by dense forests and proximity to water bodies, while anthropogenic factors such as pastures and road networks negatively impact their presence.

Evolution of research on global amphibian declines. [PDF]

Conserv Biol
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Systematic conservation prioritization with the prioritizr R package. [PDF]

Conserv Biol
Abstract Plans for expanding protected area systems (prioritizations) need to fulfill conservation objectives. They also need to account for other factors, such as economic feasibility and anthropogenic land‐use requirements. Although prioritizations are often generated with decision support tools, most tools have limitations that hinder their use for ...
