and complex, including increased precipitation, increased frequency of heavy precipitation …

Although the prevailing paradigms in spatial ecology have treated dispersal as a stochastic
process, there is an increasing awareness that spatial processes are non‐random such that …

Prey species often congregate in groups to detect and evade predators, yet not all group
members benefit equally. We observed the nesting aggregations of bluehead chub …

Nesting animals require information about their environment to place nests in optimal
locations. This information can either be derived from an animal's previous experiences …

Ecological disturbances may affect both habitat connectivity and heterogeneity, changing

In polygamy, individuals interact in a non-random manner to shape reproductive networks.
However, relative importance of behavior versus individual physical traits (eg, body size) in …

Nest construction is an energetically costly behavior displayed by males in many taxa. In
some species, males construct nests and co‐breed with other males and they may construct …

The bluehead chub (Nocomis leptocephalus) is a keystone species, an ecosystem engi-
