- 摘要：
- , they demonstrate the utility of integrating temporal dynamics of prey availability into investigations of predator-prey interactions, and move towards a mechanistic
Data from: Mismatch between dietary requirements for lipid by a predator and availability of lipid in prey

- DOI：
- doi:10.5061/dryad.13173
- 摘要：
- nutritional requirements and prey nutrient availability likely presents a challenge to spiders seeking to maximize growth in the field. Several hypotheses for how these
Data from: 18S rRNA metabarcoding diet analysis of the predatory fish community across seasonal changes in prey availability

- DOI：
- doi:10.5061/dryad.4hj4f77
- 摘要：
- , when prey availability is low and most females are unmated (i.e. post-copulatory sexual selection is weak). Nuptial gift construction correlated positively

- 摘要：
- Large-scale ungulate migrations result in changes in prey availability for top predators and, as a consequence, can alter predator behavior

- relative importance of abundance and accessibility is essential for the design and evaluation of effective management responses to reduced prey availability
Data from: Environmental heterogeneity amplifies behavioural response to a temporal cycle

- 摘要：
- t seldom stay constant. For predators, prey availability can vary at fine spatial and temporal scales as a result of changes in the physical environment
