Elevational migration can be defined as roundtrip seasonal movement that involves upward
and downward shifts in elevation. These shifts incur physiological challenges that are …

Background Seasonal movements of animals often result in the transfer of large amounts of
energy and nutrients across ecosystem boundaries, which may have large consequences …

Ongoing environmental changes alter how natural selection shapes animal migration.
Understanding how these changes play out theoretically can be done using evolutionary …

Inter‐individual variability in behavior has been studied extensively for a wide range of
species. However, few researchers have considered marginality, defined as the degree to …

Temporal synchronization is a relatively common ecological phenomenon in population
dynamics. Examples range from annual and biennial plants to Salmon to Cicadas. In …

An Allee effect is a density-dependent phenomenon in which population growth or individual
components of fitness increase as population density increases. Understanding the density …

Predicting population responses to environmental changes requires understanding
interactions among environmentally induced phenotypic variation, selection, demography …

Using a stage-structured matrix model, we examine how the ideal free distribution (IFD)
arises in the context of a partially migrating population. Partial migration is a unique form of …
