Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots. [PDF]

Conserv Biol
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Identifying priority areas for conservation to promote connectivity and mitigate the impacts of anthropogenic disturbance. [PDF]

Conserv Biol
Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

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.

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 ...

Urbanization of seed dispersal networks. [PDF]

Conserv Biol
Abstract Rapid urban expansion is affecting the composition of wild communities and creating novel ecosystems worldwide. Seed dispersal is key for ecosystem persistence, particularly in fragmented landscapes. However, generalizations regarding the impacts of urbanization are still difficult due to the lack of studies encompassing the urban matrix.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]

Mol Ecol
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Avifauna del Corredor Biológico Amistosa, Puntarenas, Costa Rica

Cuadernos de investigación UNED, 2021
Introducción: Las aves son particularmente susceptibles a la fragmentación del hábitat, lo que pone en peligro a las poblaciones locales e incluso a especies enteras. Los corredores de vegetación son una herramienta útil para conectar áreas protegidas y

Educación ambiental: itinerario en la naturaleza y su relación con conectividad, preocupaciones ambientales y conducta [PDF]

, 2013
Las excursiones e itinerarios a través de entornos naturales son frecuentes en la educación ambiental, pero existe poca evidencia empírica de investigaciones que aporten resultados que permitan comprender mejor los efectos de las experiencias de contacto
