Data from: Severe recent decrease of adult body mass in a declining insectivorous bird population
- 负责人:
- DOI:
- doi:10.5061/dryad.67t23
- 摘要:
- . Our dataset was collected over 7 years (2005–2011) and included 2918 swallow captures and 1483 broods. Analyses revealed a substantial decline of the population
Data from: Senescent declines in elite tennis players are similar across the sexes

- 摘要:
- Aging is characterized by rising mortality, declining fertility and declines in physiological function with age (functional senescence). Sex
Data from: Gene expression changes in male accessory glands during ageing are accompanied by reproductive decline in Drosophila melanogaster
- 负责人:
- DOI:
- doi:10.5061/dryad.7m644
- 摘要:
- expression with advancing age and an accompanying decline in male post-mating success. Hence, male reproductive senescence is associated with a decline in functionali
Data from: Global decline of bumblebees is phylogenetically structured and inversely related to species range size and pathogen incidence

- doi:10.5061/dryad.71q32
- 摘要:
- ies extinction risk. We applied such an approach to analyse patterns of bumblebee (Bombus) decline. We assembled a database representing approximately 43% of the circa 260 globally
Data from: Estimated six percent loss of genetic variation in wild populations since the industrial revolution
- 负责人:
- DOI:
- doi:10.5061/dryad.8c4c359
- 摘要:
- n of 27 generations for 91 species, we conservatively estimate a 5.4-6.5% decline in within-population genetic diversity of wild organisms sinc
Data from: Rainy springs linked to poor nestling growth in a declining avian aerial insectivore (Tachycineta bicolor)
- 负责人:
- DOI:
- doi:10.5061/dryad.7m41jd8
- 摘要:
- t forage on flying insects for whom effects mediated by their shared food resource have been proposed to cause avian aerial insectivores’ decline worldwide
Data from: Senescence of maternal effects: aging influences egg quality and rearing capacities of a long-lived bird
- 负责人:
- DOI:
- doi:10.5061/dryad.1109
- 摘要:
- ween females of different ages, we tested whether reproductive senescence is due to decline in egg quality or capacity to care. As laying mothers aged, egg size
Data from: Fitness decline in spontaneous mutation accumulation lines of Caenorhabditis elegans with varying effective population sizes
- 负责人:
- DOI:
- doi:10.5061/dryad.v5012
- 摘要:
- . Larger populations (N = 10 and 100) did not suffer a significant decline in fitness traits despite a lengthy and sustained regime of consec
Data from: Brain myo-inositol as a potential marker of amyloid-related pathology: a longitudinal study.

- 摘要:
- in non-demented individuals; to explore the relationship between MRS and cognitive decline. Methods: In this longitudinal multiple time point study (a subset
Data from: Fitness decline under osmotic stress in Caenorhabditis elegans populations subjected to spontaneous mutation accumulation at varying
- 负责人:
- DOI:
- doi:10.5061/dryad.d6441s7
- 摘要:
- , we measured fitness under osmotic stress via exposure to hypersaline conditions. The fitness of Ne = 1 lines exhibited a further decline under osmotic stress
