Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Mapping and verifying potential continuous cover forestry areas from LiDAR data
Continuous cover forestry (CCF) is a forest management approach where clear-cuts are avoided. Instead, the largest trees are removed, which leaves room for the smaller trees to mature, and enables natural regeneration in the canopy gaps.

Diversity of understorey at Singkil Swamp Wildlife Reserve
Abstract Singkil Swamp Wildlife Reserve (SSWR) is the only conservation area in the coastal lowlands of Aceh as well as habitat of protected large mammals and migratory birds. Many publications related to Singkil swamp biodiversity have been published; however the understory communities were not studied.

Background Livestock grazing and ‘overabundance’ of large wild herbivores in forested areas have long been perceived as conflicting with the aims of both silviculture and forest conservation; however, certain kinds of herbivory can help to maintain ...

Identification of ash-associated understorey diversity—a lesson from historical vegetation records
Key message Forest communities historically dominated by common ash (Fraxinus excelsior L.) were characterized by particularly high species richness in the understorey and included a distinct set of vascular plant species statistically associated with ...

Environmental characteristics drive variation in Amazonian understorey bird assemblages
Tropical bird assemblages display patterns of high alpha and beta diversity and, as tropical birds exhibit strong habitat specificity, their spatial distributions are generally assumed to be driven primarily by environmental heterogeneity and interspecific interactions.

Understorey Regeneration of Lophira alata as Affected by Seed Tree Size and Growing Conditions [PDF]
Demographic pressure and slash and burn practices are two factors which reduce the number of Lophira alata plants in its natural range where it is more represented by young plants.
