Since species may be the only "real thing" in systematics, everything else taxonomically being human abstractions, many phylogenetic studies have addressed particular genera, often those that can be used to investigate important evolutionary or biogeographical
relationships of North American Tertiary floras.
rhombosomoides at three localities in the Daintree--Cape Tribulation region (and the likelihood that it occurs, or previously occurred at a fourth locality) extends the range of this species some 120 km to the north of the currently recognised range and into a biogeographical
province (9--Daintree--Bloomfield) where it was previously unknown.
If this is true, it should be considered how long-distance directional dispersal occurs within populations of Ryukyu Scops Owl among the islands despite the biogeographical
Main conclusions: Although low sea levels during the Pleistocene in all probability facilitated the dispersal of freshwater crabs among the Greater Sunda islands (excluding Sulawesi, which is not part of the Sunda Shelf), there is no complete Pleistocene geographical admixture of species, and pre-Pleistocene biogeographical
patterns were retained.
This study suggests that temporal variation in fish species composition in streams of upper Paraguay and Parana basins present a predictable pattern constrained by altitude, despite of biogeographical
differences between regions.

RESULTS AND DISCUSSION--Our analyses revealed significant biogeographical

Highest densities occur north of Point Conception, which is the boundary between north Oregonian (cold) and south San Diegian (temperate) biogeographical
Their topics include species performance and treatment effectiveness for revegetating the Mojave Desert in the US, soil acidification and buffering mechanisms in the boreal biogeographical
region, analyzing shadows to measure soil surface roughness to evaluate wind erosion, a case study in northern China of a new concept and measures to control wind erosion in agricultural land, and the effects of solar disinfection and heating on the sensitivity of virulent multiple-antibiotic resistance and non-virulent sensible strains of non-01 Vibrio cholerae and fecal coliforms isolated from Marrakesh groundwater.
On my first personal meeting with Camargo in 2005, I praised the rigor with which he performed his taxonomic revisions and identifications, but Camargo merely replied that those were the necessary steps for him to achieve his ultimate goal of elucidating the biogeographical
history of the Amazonian region of South America.
