El futuro de los pastizales sudamericanos [PDF]

, 2011
Los pastizales de Sudamérica mantienen actividades de pastoreo de subsistencia y comerciales, y son un factor clave en la economía de muchos países. Esta actividad depende en forma directa del clima, principalmente las lluvias. La cantidad y distribución

Diversidad y distribución de acridios (Orthoptera: Acridoidea) en pastizales del sur de la región pampeana, Argentina [PDF]

Revista de Biología Tropical, 2013
Los acridios son componentes nativos de los pastizales, dichos sistemas han sido modificados debido a la intensificación de las actividades agrícola-ganaderas y por lo tanto se considera importante estudiar las comunidades de acridios asociadas.

Threats to and management of Natura 2000 protected areas relative to agricultural practices. [PDF]

Conserv Biol
Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation. [PDF]

Conserv Biol
Abstract 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.

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.

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes. [PDF]

Conserv Biol
Abstract 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 ...

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]

Glob Chang Biol
We 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.
