Many species are altering their geographic range due to climate change creating new sympatric populations of otherwise allopatric populations. We investigated whether climate change will affect the distribution and thus the pattern of hybridization b

1. Understanding species-specific habitat requirements is important in insect ecology. Co-occurrence of closely related species can provide insight into microhabitat segregation. Tiger beetles are well suited for such studies, as they occur in multi-

Habitat degradation led to local extinction of the San Francisco forktail damselfly (Ischnura gemina) in Glen Canyon Park, San Francisco, California. In this study, we reintroduced I. gemina into Glen Canyon after the damselfly’s habitat was restor

The San Francisco Bay Area hosts a diverse insect fauna and a dense cluster of urban areas. The high diversity of insects in the Bay Area arises for three primary reasons: its location in the California biotic province, the diverse local environment

Honey bee colonies are subject to numerous pathogens and parasites. Interaction among multiple pathogens and parasites is the proposed cause for Colony Collapse Disorder (CCD), a syndrome characterized by worker bees abandoning their hive. Here we pr

In allopatry and in a hybrid zone, we analyzed the relationship between morphometric characters and the inferior abdominal appendage angle in two damselflies, Ischnura gemina (Kennedy) and Ischnura denticollis (Burmeister), to assess the taxonomic re

These parasites get into bees' nests by fooling males into trying to mate with them. The life cycles of parasites often involve complex behavioural and morphological adaptations in order to find a host. Here we report a remarkable mode of host-findin

Sexual-selection theory makes two predictions. (1) Males usually vary more in mating success than do females (the Bateman principle), and this difference should be more pronounced in sexually dimorphic, polygamous species than in non-dimorphic, monog
