Data from: Local and system-wide adaptation is influenced by population connectivity
- 负责人:
- DOI:
- doi:10.5061/dryad.2qg02qq
- 摘要:
- orly connected systems are more prone to gradual node-by-node change. We use forward-in-time simulations of multi-locus evolution to test these general predictions

- doi:10.5061/dryad.60q44
- 摘要:
- with age was curvilinear with significant variation between the seven breed categories. Mortality was higher in loose housing systems than in cages
Data from: Specifying high-altitude electrons using low-altitude LEO systems: the SHELLS model
- 负责人:

- DOI:
- doi:10.5068/D1208Q
- 摘要:
- The dataset includes a tarball of all of the data shown in the figures in the manuscript, along with the neural network coefficients as described in the Appendix of the manuscript.
Data from: On the inconsistency of pollinator species traits for predicting either response to land-use change or functional contribution
- 负责人:
- Bartomeus, Ignasi
- DOI:
- doi:10.5061/dryad.716kr
- 摘要:
- t systems. Here, we use data on crop pollination services provided by native, wild bees to explore the role of six commonly used species traits in dete
Data from: Restriction site-associated DNA sequencing (RAD-seq) reveals an extraordinary number of transitions among gecko sex-determining systems
- 负责人:
- DOI:
- doi:10.5061/dryad.n69t3
- 摘要:
- the sex chromosome systems in the large number of species with cryptic, homomorphic sex chromosomes. Restriction site-associated DNA sequencing (RAD-seq) is a critical
Data from: Quantifying ecological and social drivers of ecological surprise
- 负责人:
- DOI:
- doi:10.5061/dryad.2c8f32s
- 摘要:
- using key variables and interactions from Ostrom’s social-ecological systems framework, which integrates broader ecosystem processes (e.g. climate
Data from: Highly diversified crop-livestock farming systems reshape wild bird communities
- 负责人:
- DOI:
- doi:10.5061/dryad.rjdfn2z62
- 摘要:
- . Individual farm factors had significantly lower predictive power than farming system alone (?CIC = 80.2), suggesting crop-livestock systems may impact
Data from: Common latitudinal gradients in functional richness and functional evenness across marine and terrestrial systems
- 负责人:
- DOI:
- doi:10.5061/dryad.96096t0
- 摘要:
- ecological and evolutionary drivers. We placed species-level ecological traits into comparable multidimensional frameworks for two model systems
