Key drivers of at-vessel mortality in demersal sharks. [PDF]

Conserv Biol
Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.

Mitigating light pollution impacts on arthropods based on light-emitting diode properties. [PDF]

Conserv Biol
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

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.

LOS SISTEMAS SILVOPASTORILES INTENSIVOS (SSPI), HERRAMIENTA DE MITIGACIÓN Y ADAPTACIÓN AL CAMBIO CLIMÁTICO

Tropical and Subtropical Agroecosystems, 2014
<p>Intensive silvopastoral systems (iSPS) are emerging as a tool for mitigation and adaptation of cattle ranching to climate change (CC). Under iSPS, 12 times more beef is produced than under extensive pastures and 4.5 more beef than under improved pastures without trees, but methane (CH4) emissions do not increase in the same proportion being 6 ...

Developing European conservation and mitigation tools for pollination services: approaches of the STEP (Status and Trends of European Pollinators) project [PDF]

, 2011
Pollinating insects form a key component of European biodiversity, and provide a vital ecosystem service to crops and wild plants. There is growing evidence of declines in both wild and domesticated pollinators, and parallel declines in plants relying ...
