Moisture history and smallmammal community richness during the latest Pleistocene and Holocene, Northern Bonneville Basin, Utah
western United States, studies of the relationship between rodent species richness and precipitation have revealed only a positive relationship between these two variables. When latest Pleistocene and Holocene smallmammal assemblages from the northern
Precipitation and net primary productivity are positively correlated in arid environments. Both variables are, in turn, correlated with mammal species richness, but this relationship is not necessarily positive. In the Great Basin of the arid
Impact of smallmammal disturbances on sediment yield from grassland and shrubland ecosystems in the Chihuahuan Desert
This study aims to contribute to the literature on animal impacts on geomorphic processes by using rainfall simulation experiments to estimate the effect of small activities on sediment yield in a Chihuahuan Desert ecosystem in the American

Pikas (Ochotona), small gnawing mammals, related to rabits, range today throughout parts of the Northern Hemisphere, but had a wider distribution during the Pleistocene. The AA. discuss the paleontological remains from northeastern North America
. Forested habitats would have been isolated habitat islands, as they are today. Boreal smallmammals including pikas and heather voles, were able to colonize the Great Basin mountain ranges during the late Pleistocene.
Plant and animal remains found in packrat (Neotoma spp.) middens and cave fill from the eastern and southern Great Basin region reveal the presence of subalpine conifers and boreal mammals at relatively low elevations during the Late Wisconsin
Krotovinas, the burrows of smallmammals, are common phenomena in steppe landscapes, and for a long time they have been a major point of discussions about the genesis of Holocene Chernozems. Using the example of the Upper Palaeolithic excavations
Kostiënki and Borshchevo in the Middle Russian Steppe an integrative soil scientific approach highlights the importance of burrowing smallmammals and of krotovina fillings resulting from both bioturbation and soil erosion in the Late Pleistocene. Based
Differentiation of Europe's mammal fauna against a background of biogeographical units, the area of units and mammalian taxonomic richness

This analysis considered the relationship between the occurrence of mammals and geographical location in Europe, as well as the size of biogeographical units. It was found that there was differentiation in the qualitative composition of the mammal
. Besides area, the regional variability of environmental conditions also has a decisive influence on the distribution of mammals in Europe.
Fossiliferous middle Pleistocene sediments of the Tarija basin of southern Bolivia contain a classic Ensenandan land-mammal fauna. New carbon isotopic data reported here for 5 specimens of the grazing mammals Equus (horse) and Cuvieronius (mastodon

The AA. examined the response of a small mammalian herbivore, the bushy-tailed woodrat (Neotoma cinerea), to temperature change from 20,000 yr B.P. to present, at 5 sites within the Colorado Plateau. The investigations focused on the relationship
Pellets of Barn Owl (Tyto alba) were collected at 15 sites within a defined study area. The remains of 14,056 smallmammals found in these pellets were identified to the species level. A correlation matrix between the percentage occurence of each
About 70 examples of Quaternary fauna in China's tropics are enumerated in this paper. Of which about 40% of the examples can be found even in cooling stages, showing the smaller amplitude of climatic fluctuation during Quaternary. According
This paper assesses the preservation of biogenic isotopic composition of the collagen fraction of mammal bone and tooth from the uppermost well-defined layer of the cave (numbered 1A) and determines the ecological basis for interspecific differences
in the carbon and nitrogen isotopic compositions of mammals from other late Pleistocene sites in Eurasia.

Presentation of a zoogeographical regionalization of Europe on the basis of the contemporary distribution of mammal faunas. The richness of families, genera and species of these animals was defined on the basis of source materials. The data obtained
enabled analyses to be made of the zoogeographical similarity of the mammal species in 29 administrative units and 58 territorial-biogeographical units.
Pre-Wisconsinan mammals from Jamaica and models of late Quaternary extinction in the Greater Antilles
The purpose of this paper is : 1) to present radiometric dates for the first pre-Wisconsinan land mammal locality recognized in the West Indies, and 2) to assess the significance of this new information for existing models of Quaternary extinctions
Genetic and paleontological evidence are combining to provide a new and surprising picture of mammalian biogeography in southeastern Alaska. The AA. conclude that brown bears, and perhaps other large mammals, have continuously inhabited

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

different from those of the present, but seasonal precipitation was more equable. Relative abundance of mammal taxa and sedimentological data indicate that aridity increased at the onset of the interglacial.
