- aphid parasitism crop rotation edge effect field margin field size landscape composition landscape configuration predator-prey ratio spatial heterogeneity temporal heterogeneity
- DOI:
- doi:10.5061/dryad.2tf5j
- 摘要:
- independent landscape gradients. 3. Aphid densities were lower in landscapes with smaller field size (more field borders) coupled with high amounts of grassy

- Kravchenko, Alexandra N.
- DOI:
- doi:10.5061/dryad.gh90f5f
- 摘要:
- in a randomized complete block-design experiment, using 27 commercial-size agricultural fields. Nearby plot-scale experiments (0.02-ha to 1.0-ha plots) provided

Data from: Body size evolution in an old insect order: no evidence for Cope’s Rule in spite of fitness benefits of large size
- 负责人:
- DOI:
- doi:10.5061/dryad.755d6
- 摘要:
- We integrate field data and phylogenetic comparative analyses to investigate causes of body size evolution and stasis in an old insect order

Data from: Predation selects for smaller eye size in a vertebrate: effects of environmental conditions and sex
- 负责人:
- Johansson, Frank
- DOI:
- doi:10.5061/dryad.475bv7s
- 摘要:
- Increased eye size in animals results in a larger retinal image and thus improves visual acuity. Thus, larger eyes should aid both in finding food

Data from: Distance and size matters: a comparison of six wildlife camera traps and their usefulness for wild birds
- 负责人:
- DOI:
- doi:10.5061/dryad.693b3f4
- 摘要:
- species diversity or density are available. Hence, the goal of our study was an empirical validation of six different camera traps in the field. We observed a total n

Data from: Should mothers provision their offspring equally? A manipulative field test
- 负责人:
- DOI:
- doi:10.5061/dryad.n3k93
- 摘要:
- variation in offspring size are rare. Using a field experiment, we investigate the consequences of unequal maternal provisioning for both maternal

Data from: Cope’s Rule in a modular organism: directional evolution without an overarching macroevolutionary trend
- 负责人:
- DOI:
- doi:10.5061/dryad.nv89424
- 摘要:
- subclades show size increases: within a genus, younger species often have larger zooids than older species. Analyses of (paleo)latitudinal shifts show tha
