Impacts of Intensive Logging on the Trophic Organisation of Ant Communities in a Biodiversity Hotspot
Trophic organisation defines the flow of energy through ecosystems and is a key component of community structure. Widespread and intensifying anthropogenic disturbance threatens to disrupt trophic organisation by altering species composition and relative abundances and by driving shifts in the trophic ecology of species that persist in disturbed ecosystems. We examined how intensive disturbance...
متن کاملImpacts of Dams and Global Warming on Fish Biodiversity in the Indo-Burma Hotspot
Both hydropower dams and global warming pose threats to freshwater fish diversity. While the extent of global warming may be reduced by a shift towards energy generation by large dams in order to reduce fossil-fuel use, such dams profoundly modify riverine habitats. Furthermore, the threats posed by dams and global warming will interact: for example, dams constrain range adjustments by fishes t...
متن کاملExtinction debt in calcareous grasslands PLANT SPECIES EXTINCTION DEBT IN A TEMPERATE BIODIVERSITY HOTSPOT: COMMUNITY, SPECIES AND FUNCTIONAL TRAITS APPROACHES
Destruction and fragmentation of (semi-) natural habitats are considered the main causes of biodiversity loss worldwide. Plant species may exhibit a slow response to fragmentation, resulting in the development of an extinction debt in fragmented plant communities. The detection of extinction debt is of primary importance in habitat conservation strategies. We applied two different approaches pr...
متن کاملImpacts of nitrogen addition on plant biodiversity in mountain grasslands depend on dose, application duration and climate: a systematic review.
Although the influence of nitrogen (N) addition on grassland plant communities has been widely studied, it is still unclear whether observed patterns and underlying mechanisms are constant across biomes. In this systematic review, we use meta-analysis and metaregression to investigate the influence of N addition (here referring mostly to fertilization) upon the biodiversity of temperate mountai...
متن کاملChanges of flowering phenology and flower size in rosaceous plants from a biodiversity hotspot in the past century
Responses of plant traits to climate changes are complex, which could be mirrored by the investigations of herbarium specimens. By examining specimens of Rosa and Cotoneaster species collected since 1920s in Hengduan Mountains, we analyzed the changes of flowering phenology and flower size in the past century when climate changes were considered to be intensified. We found that flowering phenol...
