- 摘要：
- . It can even select for constancy in key life-history traits, though some exceptions are known. Changes in the level of environmental variability are ther
Data from: Foraging strategies of generalist and specialist Old World nectar bats in response to temporally variable floral resources

- DOI：
- doi:10.5061/dryad.6bg67
- 摘要：
- . Moreover, these findings demonstrate how plant flowering phenology and pollinator diet breadth can shape the frequency and constancy of pollinator
Data from: Rates of morphological evolution are correlated with species richness in salamanders

- with clade species richness, but are uncorrelated with simple estimators of net diversification that assume constancy of rates through time. This coupling bet
Data from: Biparental incubation patterns in a high-Arctic breeding shorebird: how do pairs divide their duties?
- 负责人：
- DOI：
- doi:10.5061/dryad.nh8f0
- 摘要：
- in the High Arctic. Incubation quality, measured by egg temperature and incubation constancy, showed no marked difference between the sexes. The amount of inc
Data from: Does reproductive isolation reflect the segregation of color forms in Spiranthes sinensis (Pers.) Ames complex (Orchidaceae

- 摘要：
- floral constancy to this form. The scentless, pink form was pollinated primarily by smaller bees in the genera Ceratina (Apidae), and members of the family
Data from: Multiple independent origins of intermediate species between Sorbus aucuparia and S. hybrida (Rosaceae) in the Baltic region
- 负责人：
- DOI：

- 摘要：
- by flow cytometry. Seeds were sown to check for constancy with the mother plants. Three populations from Gotland and possibly the small population from Uppland wer
Data from: Local molecular clocks in three nuclear genes: divergence times for rodents and other mammals and incompatibility among fossil calibrations.
- 负责人：
- DOI：
- doi:10.5061/dryad.8502
- 摘要：
- divergence dates may be reconciled by the local molecular clocks approach, allowing local constancy of substitution rates with variations at larger phylogenetic
Data from: Flower colour and phylogeny along an altitudinal gradient in the Himalaya of Nepal

- 摘要：
- es in the ecologically available morphospace based on pollinator species richness and the constancy of their foraging behaviour. The chromatic signals present in Nepali
Data from: Late-glacial demographic expansion motivates a clock overhaul for population genetics
- 负责人：
- DOI：
- doi:10.5061/dryad.3q24t
- 摘要：
- The molecular clock hypothesis is fundamental in evolutionary biology as by assuming constancy of the molecular rate it provides a time frame
Data from: Specialist foragers in forest bee communities are small, social or emerge early
