Dynamic sensitivity to resource availability influences population responses to mismatches in a shorebird.

Climate change has caused shifts in seasonally recurring biological events leading to the temporal decoupling of consumer-resource pairs, that is, phenological mismatching. Although mismatches often affect individual fitness, they do not invariably scale up to affect populations, making it difficult to assess the risk they pose. Individual variation may contribute to this inconsistency, with changes in resource availability and consumer needs leading mismatches to have different outcomes over time.

Behavioural adjustments in the social associations of a precocial shorebird mediate the costs and benefits of grouping decisions.

Animals weigh multiple costs and benefits when making grouping decisions. The cost-avoidance grouping framework proposes that group density, information quality and risk affect an individual's preference for con or heterospecific groups. However, this assumes the cost-benefit balance of a particular grouping is constant spatiotemporally, which may not always be true.
