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.

Ability of new protected areas to counteract losses from downgrading, downsizing, and degazettement. [PDF]

Conserv Biol
Abstract Protected area downgrading, downsizing, and degazettement (PADDD) is a common occurrence. Although PADDD is expected to weaken biodiversity protection, PADDD offsets and new unrelated protected areas (PAs) could help restore representation of biodiversity features to the reserve network affected by PADDD.
