Data from: Using targeted enrichment of nuclear genes to increase phylogenetic resolution in the neotropical rain forest genus Inga (Leguminosae
- 负责人:
- DOI:
- doi:10.5061/dryad.r9c12
- 摘要:
- DNA sequence data gives only poor phylogenetic resolution among species. Here we explore the use of larger-scale nuclear gene data obtained though targeted enrichment

- 摘要:
- vision. We analyzed variation in these three traits in D. melanogaster, D. simulans and D. mauritiana. We show that D. mauritiana generally has larger eyes

- 摘要:
- ng of forest habitat by human practices, such as forestry and agriculture, creates a larger gradient in habitat openness than available in relatively unaffected

Data from: Cooperative breeding favours maternal investment in size over number of eggs in spiders
- 负责人:
- DOI:
- doi:10.5061/dryad.t6k57
- 摘要:
- s, 1) lay fewer and larger eggs because larger offspring compete better for limited resources and become reproducers; 2) induce egg size var

Data from: Patterns of colonization and spread in the fungal spruce pathogen Onnia tomentosa
- 负责人:
- DOI:
- doi:10.5061/dryad.8281
- 摘要:
- e on spruce and pine trees, this pathogen can infect several coniferous species. In order to study the population structure of O. tomentosa, we harvested 180

Data from: Testing adaptive hypotheses on the evolution of larval life history in acorn and stalked barnacles
- 负责人:
- DOI:

- 摘要:
- , egg and larval size were closely correlated. Settlement-competent cypris larvae were larger in cold water, indicative of advantages for large juveniles

- 摘要:
- or territories with less timber harvest nearby or relatively larger trees were, in most cases, more likely to be occupied. When we estimated average effect sizes

Data from: Nest boxes increase reproductive output for Tree Swallows in a forest grassland matrix in central British Columbia
- 负责人:
- DOI:
- doi:10.5061/dryad.g85t15k
- 摘要:
- Swallows in boxes laid larger clutches (5.9 ± 0.9 eggs, N = 76) than those in tree cavities (4.2 ± 1.6 eggs, N = 67). The mean number of nestlings hatched was greater

- 摘要:
- ation traits affect species ranges at large geographic scales. Here we address patterns of co-occurrence within the genus Selaginella, an ancient lineage of free
