Patterns of species richness for blackflies (Diptera: Simuliidae) in the Nearctic and Neotropical regions
Patterns of simuliid species richness were examined over a variety of scales at 532 stream sites in the Nearctic and Neotropical regions and found richness was not highly correlated with single‐point measurements of stream conditions.
Species richness and spatial distribution of blackflies (Diptera: Simuliidae) in streams of Central Amazonia, Brazil
1. The spatial distribution and species richness of blackflies were evaluated at 58 stream sites in Central Amazonia, Brazil. Samples were taken along a north–south axis of approximately 130 km and a…
Insect Life: The Hidden Ecology of Black Flies: Sibling Species and Ecological Scale
The ability to evoke images of blood-sucking demons that stick to their prey like bulldogs and render their hapless victim “a frightful spectacle … bloody, and covered with punctures” has been honed over evolutionary time by natural selection.
Environmental factors associated with the distribution of Simulium perflavum (Diptera: Simuliidae) among streams in Brazilian Amazonia
Results agree with similar work in the Nearctic region, suggesting that the general response of black fly distribution to environmental conditions might be universal in nature.
Spatial-temporal distribution of preimaginal blackflies in Neotropical streams
The current study investigates the spatial-temporal distribution of preimaginal blackflies in three a priori established, adjacent areas of Brazil and Venezuela. First we tested the hypothesis that…
SAMPLING AND STATISTICS IN UNDERSTANDING DISTRIBUTION OF BLACK FLIES LARVAE (DIPTERA: SIMULIIDAE)
A standardized set of protocols for collecting both larval black flies (Diptera: Simuliidae) and the accompanying stream data and simple statistical procedures for producing species distribution models are presented.
Scale, time, space, and predictability: species distributions of preimaginal black flies (Diptera: Simuliidae)
Predictability of species distributions at a fixed scale can vary with geographic location and time, and the critical role of taxonomic resolution linked with spatial and temporal scale of observation is emphasized in elucidating patterns of species assemblages.
Context‐dependent symbiosis between black flies (Diptera: Simuliidae) and trichomycete fungi (Harpellales: Legeriomycetaceae)
The trichomyceteblack fly relationship represents a rare case of symbiosis shifting among three states: commensalistic when larvae are well fed, mutualisticWhen larvae are starved, and parasitic in adults.
Prevalence of the trichomycete fungus Harpella melusinae (Harpellales: Harpellaceae) in larval black flies (Diptera: Simuliidae) across a heterogeneous environment
Ecological conditions can serve as predictors of the prevalence of H. melusinae in larvae of Simulium tuberosum cytospecies “A” was highest in acidic streams with low conductivity, whereas H.Melusinee colonized larvae ofSimulium verecundum most frequently in slower-moving streams.
The roles of abiotic factors, dispersal, and species interactions in structuring stream assemblages of black flies (Diptera: Simuliidae)
BackgroundThe patterns and drivers of species assemblages represent the core of community ecology. We focus on the assemblages of a single family of ubiquitous lotic insects, the Simuliidae (black…
