Data from: Spending limited resources on de-extinction could lead to net biodiversity loss
- 负责人：
- DOI：
- doi:10.5061/dryad.p86t5
- 摘要：
- to predict the impacts of reintroducing and maintaining populations of these species on conservation of extant threatened species. Even using the optimistic
Data from: Species diversity can be overestimated by a fixed empirical threshold: insights from DNA barcoding of the genus Cletus (Hemiptera
- 负责人：
- DOI：
- doi:10.5061/dryad.qp1nd
- 摘要：
- The use of genetic distances to identify species within the framework of DNA barcoding has to some extent improved the development of biodiversity
Data from: Latitudinal biodiversity gradients at three levels: linking species richness, population richness, and genetic diversity
- 负责人：
- DOI：
- doi:10.5061/dryad.xgxd254ck
- 摘要：
- species or populations in an area, respectively. Population richness can be totalled across species, within a species or averaged across species
Data from: The role of species pools in determining species diversity in spatially heterogeneous communities
- 负责人：

- DOI：
- doi:10.5061/dryad.5gn79
- 摘要：
- -specific species pool hypothesis in a local, environmentally heterogeneous community of annual plants using a novel 'ecological selection' expe
Data from: Geographic ranges of genera and their constituent species: structure, evolutionary dynamics, and extinction resistance
- 负责人：
- 关键词：
- DOI：
- doi:10.5061/dryad.nh6hm
- 摘要：
- We explore the relationships among the geographic ranges of genera, the ranges and positions of their constituent species, and the number of species
Data from: Decoupling of latitudinal gradients in species and genus geographic range size: a signature of clade range expansion
- 负责人：
- DOI：
- doi:10.5061/dryad.23cn7
- 摘要：
- therefore depend partly on a clade’s tendency to produce new species. Under high speciation pressure, species-rich clades can migrate outside its present
Data from: Alien species richness is currently unbounded in all but the most urbanized bird communities
- 负责人：
- DOI：
- doi:10.5061/dryad.kv3dm37
- 摘要：
- alien species richness in urban areas, or whether other processes would act to impose an upper limit on species richness, we examined how the shape
Data from: Model-based species delimitation: are coalescent species reproductively isolated?
- 负责人：
- DOI：
- doi:10.5061/dryad.fk869rf
- 摘要：
- A large and growing fraction of systematists define species as independently evolving lineages that may be recognized by analyzing
Data from: Speciation history of a species complex of Primulina eburnea (Gesneriaceae) from limestone karsts of south China, a biodiversity hotspot
- 负责人：
- DOI：
- doi:10.5061/dryad.8b69r
- 摘要：
- delimitation, population genetic analyses, simulations of gene flow, and analyses of floral morphological traits to infer the geographic history of speciation in a species

- 摘要：
- We describe two new frog species of Cardioglossa (Family Arthroleptidae) from Central Africa. The new species are found in the rainforests of wes
