Sampling Bee Communities (Hymenoptera: Apiformes) in a Desert Landscape: Are Pan Traps Sufficient?
Though pan trapping constitutes a standardized method that avoids collector bias, it may not be unbiased; capture rates were lowest when flowering plant richness was greatest, and net collecting should be used in addition to pan traps if comprehensive inventories are desired.
Illuminating the lack of consensus among descriptions of earth history data in the North American deserts: A resource for biologists
Understanding the timing of mountain building and desert formation events in western North America is crucial to understanding the evolutionary history of the diverse arid-adapted biota that is found…

A large Müllerian mimicry complex in North American velvet ants (Hymenoptera: Mutillidae) is identified and it is found that 65 species in the velvet ant genus Dasymutilla can be placed into one of six morphologically distinct and geographically delimited mimicry rings.
The population ecology of novel plant–herbivore interactions
A conceptual model is described for the colonization of a novel host-plant, which focuses on the relationship between occupancy and availability and hypotheses are suggested that involve dispersal and, most important, population growth rate of an insect herbivore associated with an exotic host.
The evolution of novel host use is unlikely to be constrained by trade‐offs or a lack of genetic variation
Results suggest that genetic trade‐offs are not the primary cause of dietary specialization in L. melissa butterflies, and most genetic variants that affected performance on one host had little to no effect on the other host.
Identifying Pleistocene refugia in North American cold deserts using phylogeographic analyses and ecological niche modelling
It is suggested that during the cooling of the glacial periods, arid-adapted organisms were restricted to refugia in the Sonoran and Chihuahuan deserts, and should be considered a high conservation priority as important areas for maintaining species and genetic diversity.
Revisiting the Great American Biotic Interchange through analyses of amphitropical bees
This study is the first to show a Miocene connection for an amphitropically-distributed insect group, and suggests that the biotic connection between continents is more complicated than previously thought and may have initiated long before the late Pliocene.
The Bees in Your Backyard: A Guide to North America's Bees
The Bees in Your Backyard provides an engaging introduction to the roughly 4,000 different bee species found in the United States and Canada, dispelling common myths about bees while offering…
Müllerian Mimicry as a Result of Codivergence between Velvet Ants and Spider Wasps
The breadth of the Dasymutilla Müllerian mimicry complex is expanded and insights about how codivergence influenced the evolution of mimicry in these groups are provided.
Interest exceeds understanding in public support of bee conservation
It is found that although 99% of respondents believed that bees are critical or important, only 14% were able to guess within 1000 the actual number of bee species in the US, and many respondents were unable to discern bees from non-bees.
