The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Marxismo, autopropiedad y abundancia
Crítica (México D F En línea), 2013 G.A. Cohen y John Rawls atribuyen a Karl Marx haberse adherido al principio libertarista de autopropiedad y una plena confianza en la abundancia ilimitada como solución a los defectos distributivos del socialismo. Asimismo, consideran que el comunismo marxiano está, en cierto sentido, más allá de la justicia.

A global assessment of animal community responses to agricultural management
Conservation Biology, EarlyView.Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

Coinvasional disruptions to island pollinator networks
Conservation Biology, EarlyView.Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Entre el paraíso de la abundancia y el infierno del hambre: mitos y realidades
Cuadernos de Historia Moderna, 2015 Entre los sueños y la realidad, la tierra de Jauja, como Cucaña, era un país mágico insistentemente imaginado y buscado durante la Edad Moderna. En esta tierra fantástica no era necesario trabajar y el alimento era abundante.

Anales de la Universidad de Chile, 2011 Como nunca, el panorama de la politica nacional juega a la esquizofrenia: las loas al desarrollo del pais -particularmente medido desde una perspectiva exclusivamente economica,que tiene un correlato social en el vuelco hacia el consumo- conviven con un malestar subterraneo y sordo.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Latin American Journal of Aquatic Research, 2015 A quantitative study of metazoan meiofauna was carried out in Valparaiso Bay (33°S 71°W) which is affected by seasonal hypoxia in central Chile. The contents of bottom water, dissolved oxygen (BWDO), organic carbon, chloroplast pigments and composition ...

Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Conservation Biology, EarlyView.Abstract The United Nations and European Union have set ambitious conservation goals to halt and reverse declines in biodiversity by protecting 30% of land and sea areas by 2030. Effective conservation planning requires evidence‐based spatial prioritization to maximize the coverage of species within designated protected areas.
