Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca
EspañolAntecedentesEste estudio se llevó a cabo en Coto Brus, y se enfoca en la restauración de paisajes agrícolas fragmentados dentro del Corredor Biológico Amistosa. El mismo es un área prioritaria para la forestería y la conservación en Costa Rica que ha sido degradrada y transformada por la expansión agrícola durante los pasados 50 años, dejando solo un 25% del bosque original.

Characterization of Andean forest edges and implications for ecological restoration in Cogua Forest Reserve, Colombia (Caracterización de bordes de bosque altoandino e implicaciones para la restauración ecológica en la Reserva Forestal de Cogua, Colombia)EspañolantecedentesLa capacidad regenerativa de los bosques fragmentados es determinada por las características particulares del parche, así como de la zonas de borde. Conocer esta información es crucial para la implementación de iniciativas de restauración, en este del Bosque Altoandino de Colombia. Open access copy available |

Tree density, basal area and species diversity in a disturbed dry tropicalforest of northern India: implications for conservationBackgroundDry tropical forest communities are among the world’s most threatened systems. Rapid measures are required to protect and restore them in degraded landscapes. For planning conservation strategies, there is a need to determine the essential measurable properties, such as number of species and basal area, that best describe the dry forest vegetation and its environment, and to document quantitative relationships among them.

La vegetación leñosa en helechales y bosque de ribera en la reserva científica Ebano Verde, República Dominicana (Woody vegetation in fernlands and riparian forests in Ebano Verde scientific reserve, Dominican Republic)SpanishAntecedentesDe 1940 a 1970, áreas deforestadas en la Cordillera Central de la República Dominicana fueron sujetas a incendios rutinarios lo cual causó erosión intensa y llevo al establecimiento de Dicranopteris pectinate, una especie de helecho de sotobosque. Esta especie de helecho rápido forma comunidades estables que inhiben el crecimiento de especies maderables e impide la sucesión natural del bosque. Se ha observado un fenómeno similar dentro de la Reserva Científica Ébano Verde en la República Dominicana. Open access copy available |

Forest Recovery after Swidden Cultivation across a 40-year Chronosequence in the Atlantic Forest of Southern Bahia, BrazilbackgroundSecondary forest with a range of ages was compared to old growth forest in the Serra do Conduru State Park in Southern Bahia, Brazil in terms of species composition and structure.

Tree species diversity and vegetation structure in shade coffee farms in Veracruz, MexicoBackgroundWhile some studies have argued that shade coffee enables similar biodiversity to remnant forest fragments, others contest that the ecological functions of shade coffee can be assumed to be the same or that policies promoting shade coffee will also benefit remnant forest fragments. Not all taxa have been thoroughly studied in shade coffee. This study reports on tree species diversity and vegetation structure in shade coffee farms in Veracruz, Mexico.

Tree biodiversity in farmer cooperatives of a shade coffee landscape in western El SalvadorbackgroundConservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. Understanding the types of biodiversity common in agriculturally managed lands, and involving farmers in conservation planning, is important for regional conservation goals.

Seed Dispersal Distances and Plant Migration Potential in Tropical East AsiaBackgroundMost predictions of vegetation responses to anthropogenic climate change over the next century are based on plant physiological tolerances and do not account for the ability of plant species to migrate over the distances required in the time available, or the impact of habitat fragmentation on this ability. This review assesses the maximum routine dispersal distances achievable in tropical East Asia and their vulnerability to human impacts. Available with subscription or purchase |
