Facilitation of Yucca brevifolia recruitment by Mojave Desert shrubs
… predicted by either their canopy area or numerical dominance. The research indicates there is strong micro-habitat specificity for Yucca brevifolia recruitment under the canopy of nurse plants. These data also suggest that the local presence of specific perennial shrubs resulted in higher …

The Ecology of Mayflies (Ephemeroptera) in the Guadalupe River Basin, Texas
… fed by surface runoff had more species and numerical dominance was more evenly distributed among the taxa. Life histories for all species were asynchronous and multivoltine in Honey Creek, a springbrook, and the Blanco River, a surface runoff stream. This seems to be due mainly to high …

The community ecology of a riverine turtle assemblage in the Tennessee River Gorge
… generalized species will be the most numerically abundant forms present in the TRG, 2) adult sex ratios of turtle populations in the TRG will be biased in favor of males, and 3) mean adult body size measurements and size dimorphism index (SDI) values of turtle populations in the TRG …

Investigation on Mt. Etna dynamics by seismic and acoustic signals (August 2007-December 2010)
… out on the infrasound signals, revealed the numerical dominance and the steadiness of NEC events, radiating almost continuously acoustic energy, oppositely to SEC and EF. Furthermore, NEC events most relevant changes (spectral and amplitude variation) occurred systematically after the renewal …

Dedicated dads: a study on the nesting behaviour of Spondyliosoma emarginatum (Telostei: Sparidae)
… This strategy may explain its success and numerical dominance in a wide range of biogeographic zones. The nesting behaviours shares much in common with freshwater opportunistic fish species and set it apart from the bulk of the Sparidae.

Effects of fragmentation and invasion on ant communities
… I focused on ants due to their ecological dominance, sensitivity to habitat transformation and disturbance, and their success as invaders. Ants, with 16 subfamilies and almost 14,000 species, are distributed globally and stand out for their dominance in biomass among terrestrial …
