Community And Functional Ecology Of Lianas In The Yasuní Forest Dynamics Plot, Amazonian Ecuador, Hugo Geovanny Romero-Saltos
Community And Functional Ecology Of Lianas In The Yasuní Forest Dynamics Plot, Amazonian Ecuador, Hugo Geovanny Romero-Saltos
Open Access Dissertations
I studied the community of lianas in the Yasuní Forest Dynamics Plot (YFDP), in Amazonian Ecuador. I found that species diversity of lianas in valley habitat was higher than in ridge habitat, but liana abundance was similar. I also found that community structure (species composition and their abundances) of lianas in ridge was distinct from that in valley because of the differential distribution and abundance of certain species along the topographic gradient. In an attempt to explain this phenomenon deterministically, I took two approaches: (1) to explore if trait expression of leaf-based traits, wood specific gravity and stem growth rate …
Review Of Acanthocephala (Hemiptera: Heteroptera: Coreidae) Of America North Of Mexico With A Key To Species, J. E. Mcpherson, Richard J. Packauskas Ph.D., Robert W. Sites, Steven J. Taylor, C. Scott Bundy, Jeffrey D. Bradshaw, Paula Levin Mitchell

A review of Acanthocephala of America north of Mexico is presented with an updated key to species. A. confraterna is considered a junior synonym of A. terminalis, thus reducing the number of known species in this region from five to four. New state and country records are presented.

We conducted a statistical analysis to characterize the influence of large-scale and local environmental factors on presence-absence, concentration, and assemblage structure of larval fish within the northern California Current (NCC) ecosystem, based on samples collected at two nearshore stations along the Newport Hydrographic line off the central Oregon coast. Data from 1996 to 2005 were compared with historical data from the 1970s and 1980s to evaluate pseudo-decadal, annual, and seasonal variability. Our results indicate that the most abundant taxa from 1996 to 2005 differ from those of earlier decades. Concentrations of the dominant taxa and total larvae were generally greater …
