Homology and phylogenetic implications of male genitalia in Diptera - Eremoneura
The above characters support the monophyly of the Eremoneura and also indicate that the Empidoidea and Cyclorrhapha are sister groups, as opposed to alternative hypotheses that suggest the EmPidoideA is paraphyletic with respect to the Cyclor rhapha. Expand
TACHINIDAE: evolution, behavior, and ecology.
Way in which investigation of these parasitoids provides insight into such topics as biogeographic patterns of diversity, the evolution of ecological specialization, the tritrophic context of enemy-herbivore interactions, and the role of host location behavior in shaping host range is highlighted.

DNA barcodes affirm that 16 species of apparently generalist tropical parasitoid flies (Diptera, Tachinidae) are not all generalists
The results reinforce the emerging suspicion that estimates of global species richness are likely underestimates for parasitoids and that the strategy of being a tropical generalist parasitic fly may be yet more unusual than has been envisioned for tachinids. Expand
Homology and phylogenetic implications of male genitalia in diptera - lower Brachycera
Homology of male genitalic structures in the lower Brachycera is examined and implications for the phylogenetic relationships of the included families are discussed in light of other characters. TheExpand
Integration of DNA barcoding into an ongoing inventory of complex tropical biodiversity
Adding DNA barcoding to the inventory of the caterpillars, their food plants and parasitoids in northwestern Costa Rica has substantially improved the quality and depth of the inventory, and greatly multiplied the number of situations requiring further taxonomic work for resolution. Expand
Early primary succession on the volcano Mount St. Helens
Experiments and fine-scale observations suggest that successional sequences on Mount St. Helens are not mechanistically necessary, rather, they result from local cir- cumstances, landscape effects and chance. Expand
The male genital tract and aedeagal components of the Diptera with a discussion of their phylogenetic significance
The male genital tract of Diptera is surveyed, based on whole dissections, with emphasis on nematocerous infraorders and especially the Culicomorpha, and there is no convincing evidence for the monophyly of the Chironomoidea. Expand
Effects of the frequency, timing, and intensity of simulated browsing on growth and mortality of tree seedlings
It is demonstrated that even 2 successive years of heavy winter clipping has little immediate effect on growth or survival of any of the three species. Expand
The Role of Lupine in Succession on Mount St. Helens: Facilitation or Inhibition?
Investigation of the influence of Lupinus lepidus, a nitrogen-fixing pioneer species, on two invading species shows that both facilitation and inhibition occurred, but at different stages in the life cycle of invading species. Expand
