Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation. [PDF]
Conserv BiolAbstract As land use intensifies globally, it increasingly exerts pressure on protected areas. Despite open, nonforested landscapes comprising up to 40% of protected areas globally, assessments have predominately focused on forests, overlooking the major pressures on rangelands from livestock overgrazing and land conversion.

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes. [PDF]
Conserv BiolAbstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

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 EvolOur 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.

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]
Glob Chang BiolWe studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.

Landscape-scale predictions of future grassland conversion to cropland or development. [PDF]
Conserv BiolAbstract Grassland conservation planning often focuses on high‐risk landscapes, but many grassland conversion models are not designed to optimize conservation planning because they lack multidimensional risk assessments and are misaligned with ecological and conservation delivery scales.
