The prospects for persistence of bees living in fragmented landscapes is a topic of considerable interest due to bees’ importance as pollinators of agricultural crops and wild plants, coupled with the ubiquity of native habitat loss and evidence that bees may be declining worldwide. Population persistence in fragmented areas depends on dispersal potential(More)
Varroa destructor is an obligate ectoparasitic mite and the most important biotic threat currently facing honey bees (Apis mellifera). We used neutral microsatellites to analyze previously unreported fine scale population structure of V. destructor, a species characterized by extreme lack of genetic diversity owing to multiple bottleneck events,(More)
Paul was just 15 when he met Michener (Mich), who was curator of Lepidoptera at the American Museum of Natural History. He seemed to be very old to Paul (Mich was 29) and Paul thought even then that Mich was a great scientist (he was right). Mich was doing research on the taxonomy of butterflies and moths because he couldn't find employment working with(More)
Metallic coloration is one of the signatures of orchid bees of the genus Euglossa, with some species showing variation associated with their geographic range. Euglossa (Alloglossura) gorgonensis Cheesman exhibits color variation, ranging from mainly green specimens in the southern extreme of its range (Pacific slope of Colombia), to noticeably reddish(More)
Globally, most restoration efforts focus on re-creating the physical structure (flora or physical features) of a target ecosystem with the assumption that other ecosystem components will follow. Here we investigate that assumption by documenting biogeographical patterns in an important invertebrate taxon, the parasitoid wasp family Ichneumonidae, in a(More)
Patterns of discrete behaviors tied together in specific sequences are essential for the formation of complex behavioral phenomena. Such behavioral sequences can be of critical ecological importance, for example relating to resource acquisition, predator evasion, and sexual selection. The role of sequential behaviors in ecology, however, is understudied, in(More)
Landscape Ecology addresses large-scale spatial pattern and process in biology, a topic with deep linkages to sustainability, primarily through its connection to conservation biology. This course will be taught for the first time in fall 2010, and originally, I had planned to teach it with a more or less exclusive focus on ecological theory. Participating(More)
PREMISE OF THE STUDY DNA metabarcoding has broad-ranging applications in ecology, aerobiology, biosecurity, and forensics. A bioinformatics pipeline has recently been published for identification using a comprehensive database of ITS2, one of the common plant DNA barcoding markers. There is, however, no corresponding database for rbcL, the other primary(More)
