Habitat quality is more important than matrix quality for bird communities in protected areas
2018
Protected areas are meant to preserve native local communities within their boundaries, but they are not independent from their surroundings. Impoverished habitat quality in the matrix might influence the species composition within the protected areas through biotic homogenization. The aim of this study was to determine the impacts of matrix quality on species richness and trait composition of bird communities from the Finnish reserve area network and whether the communities are being subject of biotic homogenization due to the lowered quality of the landscape matrix. We used joint species distribution modeling to study how characteristics of the Finnish forest reserves and the quality of t…
Seabird influence on ecological processes in coastal marine ecosystems: an overlooked role?
2013
Coastal marine ecosystems and especially transitional environments host a large variety of birds, functioning as nesting sites for resident species and corridors for migratory ones. Seabirds activity may trigger movement of nutrients and organic matter between coastal boundaries, affecting their availability and processing. Consequently seabirds are often labelled as biotic vectors. While attention has been focused on the study of biodiversity level and migratory patterns of avifauna, there is little information on the effects of seabirds on ecological features (i.e. trophic status, biodiversity level, food web patterns, transfer of contaminants) in coastal marine ecosystems. To address the…
