Reconsidering the role of introduced species in the climate-affected and highly invaded eastern Mediterranean. [PDF]

Conserv Biol
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity. [PDF]

Glob Chang Biol
Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

Dietary resilience of coral reef fishes to habitat degradation. [PDF]

J Anim Ecol
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

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.

Mapping illegal trade routes of live cheetahs from the Horn of Africa to the Arabian Peninsula. [PDF]

Conserv Biol
Abstract Less than 7000 cheetahs (Acinonyx jubatus) persist in Africa. Although human–wildlife conflict, habitat degradation, and loss of prey are major threats to cheetah populations, illegal trade in live cubs for pets may have the most significant impact on populations in the Horn of Africa.

Role of protected areas in mitigating range loss and local extinctions of terrestrial mammals. [PDF]

Conserv Biol
Abstract Protected areas (PAs) are a major tool in biodiversity conservation, but the extent to which they mitigate species declines is often unclear. We evaluated the effectiveness of PAs in mitigating range contraction and local extinction for 483 terrestrial mammal species.

Implications of global distributive justice principles for implementation of the Kunming-Montreal Global Biodiversity Framework. [PDF]

Conserv Biol
Abstract In the era of the sixth mass extinction, reversing global biodiversity loss is of vital importance for life on Earth. In 2022, parties to the Convention on Biological Diversity (CBD) adopted the Kunming‐Montreal Global Biodiversity Framework (GBF), a strategic plan with 23 action‐oriented targets to be achieved by 2030.

Diversidad de anfibios y reptiles en hábitats altoandinos y paramunos de la cuenca del río Fúquene, Cundinamarca, Colombia

Biota Colombiana, 2014
En la actualidad los ecosistemas altoandinos y de páramo en Colombia se encuentran amenazados como resultado de la degradación del hábitat, lo que ha causado que organismos como anfibios y reptiles estén bajo alguna categoría de amenaza.

Evaluación del estado de las áreas ambientalmente sensibles a la degradación de los hábitats de dos aves endémicas del noroeste del Perú: el colibrí cola de espátula (Loddigesia mirabilis) y lechucita bigotona (Xenoglaux loweryi)

Pirineos: Revista de Ecología de Montaña, 2023
La degradación de los hábitats de especies endémicas con rangos de distribuciones restringidas, se han acelerado en los últimos años, aún más si se encuentran en peligro de extinción.

Niveles de conservación y degradación de hábitat en los ecosistemas de una cuenca de alta biodiversidad en Tamaulipas (México)

Boletín de la Asociación de Geógrafos Españoles, 2020
Los ecosistemas con flujos de servicios ambientales óptimos ofrecen una adecuada calidad en sus hábitats que coadyuvan a mantener su biodiversidad. Esta calidad puede reducirse por los factores de mayor intensidad y cercanía al hábitat, lo que puede ...
