Investigating Mechanisms of Co-Occurrence Between Two Similar Specis of Predaceous Diving Beetles (<i>Coleoptera: Dytiscidae</i>) in Temporary Aquatic Habitats
<p>Predaceous diving beetles (Coleoptera: Dytiscidae) are a model group of organisms for testing coexistence and exclusion mechanisms because numerous species of the family interact in isolated, aquatic habitats, and are ubiquitous throughout landscapes. Two morphologically similar species, …
