Data from: Genomic evidence of demographic fluctuations and lack of genetic structure across flyways in a long distance migrant, the European turtle
- 负责人:
- DOI:
- doi:10.5061/dryad.p5cf4
- 摘要:
- s multiple flyways to move between Europe and Africa. Despite being abundant, it is categorized as vulnerable because of a long-term demographic decline

Data from: Did Late Pleistocene climate change result in parallel genetic structure and demographic bottlenecks in sympatric Central Afric
- 负责人:
- DOI:
- doi:10.5061/dryad.82nt3
- 摘要:
- ng a hierarchical Bayesian model to reconstruct demographic history, we show that both species had dramatic declines (> 97%) in effective population size in the period

Data from: Comparative evaluation of potential indicators and temporal sampling protocols for monitoring genetic erosion
- 负责人:
- DOI:
- doi:10.5061/dryad.2m397
- 摘要:
- erosion following demographic decline. To do so, we utilized individual-based simulations featuring an array of different initial population sizes, types and severity

Data from: Data gaps and opportunities for comparative and conservation biology
- 负责人:
- DOI:
- doi:10.5061/dryad.nq02fm3
- 摘要:
- t only 1.3% of the tetrapod species have comprehensive information on birth and death rates. We found no demographic measures, not even crude ones such as maximum li

Data from: Holocene population decline and conservation implication for the Western Hercules Beetle, Dynastes grantii (Coleoptera, Scarabaeidae)
- 负责人:
- DOI:
- doi:10.5061/dryad.37g4f36
- 摘要:
- in the Mogollon Rim could have been the major factors shaping the population genetic structure and demographic history of D. grantii. The Western Hercules beetle

Data from: Fungal symbionts maintain a rare plant population but demographic advantage drives the dominance of a common host
- 负责人:
- DOI:
- doi:10.5061/dryad.nf515
- 摘要:
- interactions with symbionts, could be the main driver of species’ relative abundances. 2. Here, we used demographic modelling with 5 years of data from

Data from: Experimental evolution of slowed cognitive aging in Drosophila melanogaster
- 负责人:
- DOI:
- doi:10.5061/dryad.6ph62
- 摘要:
- and Young populations, revealing genetic variation for cognitive aging. We found little evidence for a genetic correlation between cognitive and demographic aging: alt

Data from: Genetic decline, restoration and rescue of an isolated ungulate population
- 负责人:
- DOI:
- doi:10.5061/dryad.n8v973b
- 摘要:
- revealed that the demographic bottleneck reduced expected heterozygosity and allelic diversity by 6.2 and 11.3%, respectively, over two genera

Data from: How climate extremes—not means—define a species' geographic range boundary via a demographic tipping point

- DOI:
- doi:10.5061/dryad.1v02q
- 摘要:
- not reflected in demographic responses to climate means, a distinction that is critical to successful ecological forecasting.

Data from: Germ banks affect the inference of past demographic events
- 负责人:
- DOI:
- doi:10.5061/dryad.7kp90
- 摘要:
- - a population expansion and an instantaneous decline. We demonstrate the appreciable influence of seed banks on the estimation of demographic parameters depending
