Stochasticity, succession, and environmental perturbations in a fluidic ecosystem.
Unraveling the drivers of community structure and succession in response to environmental change is a central goal in ecology. Although the mechanisms shaping community structure have been intensively examined, those controlling ecological succession remain elusive. To understand the relative importance of stochastic and deterministic processes in mediating microbial community succession, a uni...
متن کاملCommunity assembly during secondary forest succession in a Chinese subtropical forest
Subtropical broad-leaved forests in southeastern China support a high diversity of woody plants. Using a comparative study design with 303 30 m plots (n1⁄4 27) from five successional stages (,20, ,40, ,60, ,80, and 80 yr), we investigated how the gradient in species composition reflects underlying processes of community assembly. In particular, we tested whether species richness of adult trees ...
متن کاملNest-site partitioning in a strandveld shrubland bird community
Nest-site selection may vary adaptively among co-existing species as a result of competitive interactions among the species or in response to density-dependent nest predation. We examined nest-site characteristics and degree of partitioning among 14 co-existing bird species breeding in dwarf strandveld shrubland at Koeberg Nature Reserve, South Africa. Habitat characteristics of nest sites diff...
متن کاملPatterns and Processes of Arthropod community succession after fire
Our general purpose was to determine whether arthropod communities in midsuccessional habitat are qualitatively different from those in mature habitat. Specifically, we investigated whether foraging guild structure, abundance, and diversity differ in relation to fire history and whether there is evidence of failure in community recovery after a fire. Lastly, we compared our results for the enti...
متن کاملNitrification Potentials in Primary and Secondary Succession'
Potential nitrogen mineralization and nitrification were measured in soils from a primary successional sequence developed on sand dunes and from a secondary successional sequence on old fields. Potential nitrogen mineralization in soils from the primary sere increased through the first five stages and then leveled off. Nitrogen mineralization was relatively constant in soils from the secondary ...
