The age estimates and the faunal composition at Lainyamok indicate that geographic changes and taxonomic associations of extant large-bodied mammals were susceptible to wide fluctuations in sub-Saharan Africa over the past 330,000 yr. This inference
Aspects of the immigration of an Oriental group of cicadas eastwards of Wallace's Line into the Papuan and Melanesian areas are analyzed in a taxonomic and biogeographic study of the subtribe Cosmopsaltriaria. Comparison of a combined taxon-area
the relationships between some morphological features and the locomotion and feeding habits of the species concerned. The partitioning of the forest environment between the major taxonomic categories of neotropical lizards is discussed. The ecological specialization
Phytoplankton crops in Saanich Inlet were characterized by their content of photosynthetic pigments and by their taxonomic compositions from early April to mid-December, 1981. Crop sizes were correlated to particle volumes, bacterial activities
During the last decade Quaternary pollen analysis has developed towards improved pollen-taxonomical precision, automated pollen identification and more rigorous definition of pollen assemblages zones. There have been significant efforts to model
This study investigates the importance of scale in the functional (feeding guild) and taxonomic (species and classes) characteristics of vertebrate communities along an elevational/environmental gradient in the Sierra Nevada of California
to different taxonomic classes. These differences probably result in part from the forested ecosystem of the north-facing slope versus the savanna-like ecosystem of the opposite slope.
Plateau, Central Vietnam), performed in May 1988. 2. Thermal conditions at Bajan Bulag (Khentey Mountains, Central Mongolia) as a base of topoclimatic mapping. An effect of those studies is the map of topoclimatic types. One of the taxonomic grouping
elements does not allow a precise taxonomic identification. However, based on the morphologic features, this form can be tentatively ascribed to the suborder Lytoceratina. - (NF)
. The preservation of the specimens does not allow a detailed taxonomic interpretation and for this reason they are referred to the lungfish suborder Ceratodontoidei, leaving indeterminate their familial and generic attribution. Dipnoans constitute an additional

in taxonomic composition, density and richness among habitats within reaches strongly imply the uniqueness of these habitats in terms of the invertebrate faunas that occupy them. The AA. suggest that if maintenance of biotic diversity is an aim of instream flow
in wild yams to help to elucidate the taxonomic status of a number of species. The different underground storage structures are considered as adaptive to the rain-forest environment. An estimate of the underground tuber biomass has been made. The benefits
Ecological data indicate that as the amount of precipitation in an arid areas increases, so too does mammalian taxonomic richness. The correspondence has been found in two late-Quaternary mammalian faunas from Utah, one from Homestead Cave
by comparison with 3 profiles in a similar unit outside the sample area, named the validation area. Comparison of soil types between the unit in the sample area and the validation area at 3 scales indicated that by increasing the taxonomic accuracy, the hidden
derived from a soil's taxonomic subgroup classification, which is a reflection of its long-term wetness. Additional factors that can impact soil water content, quality, and/or availability (e.g. texture), when also reflected in taxonomy, are quantified
