Dietary resilience of coral reef fishes to habitat degradation

open access: yesJournal of Animal Ecology, EarlyView.
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 ...

Threats to and management of Natura 2000 protected areas relative to agricultural practices

open access: yesConservation Biology, EarlyView.
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.

Ecosistemas criminales

open access: yesRevista Científica General José María Córdova, 2018
El crimen organizado transnacional es quizás una de las amenazas que más retos genera a la institucionalidad de los gobiernos. Por lo tanto, entender el funcionamiento de las dinámicas de poder entre los actores al margen de la ley y la población de ciertos sectores urbanos y rurales representa uno de los intereses más importantes en materia de ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

open access: yesConservation Biology, EarlyView.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

open access: yesConservation Biology, EarlyView.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

How much biotic nativeness matters across human demographic groups

open access: yesConservation Biology, EarlyView.
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Informing spatial conservation prioritization with species’ traits

open access: yesConservation Biology, EarlyView.
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Reflexiones acerca de los ecosistemas agrícolas y la necesidad de su conservación Reflections on agricultural ecosystems and the need to preserve them

open access: yesPastos y Forrajes, 2008
La conservación de los ecosistemas agrícolas o agroecosistemas reviste una gran importancia para la seguridad alimentaria del planeta, por cuanto ellos contienen los elementos necesarios (suelo, agua y biodiversidad) que son consustanciales a la ...
