A latitudinal test of the fossorial rodent hypothesis of Mima mound origin
rodent hypothesis of Mima mound origin, and inconsistent with the other hypotheses (wind or water erosion, wind deposition, periglacial freeze thaw dynamics).
Body size variability and a Sangamonian extinction model for Amblyrhiza, a West Indian megafaunal rodent

The megafaunal rodent Amblyrhiza inundata from Anguilla and St. Martin is often cited in lists of late Quaternary human-induced extinctions, but is date of disappearance has never been established. Here, the AA. present a suite of uranium-series

Subfossil Cleopteran (beetle) remains recovered from the base of a mound at Mima Prairie consist of species that would be expected in rodent burrows and nests; all but one species are obligate burrow inhabitants. These results suggest the past
presence of fossorial rodents (probably pocket gophers, Thomomys mazama) in the mounds, although none live there at present. Whether or not the gophers created the mounds, they may well have been instrumental in maintaining mound geometry until very
Holocene vegetation history from fossil rodent middens near Arequipa, Peru
Rodent middens collected from 2350 to 2750 m elevation near Arequipa, provide an 9600-yr vegetation history of the northern Atacama Desert, based on identification of >50 species of plant macrofossils. These midden floras show considerable stability
In this work, 3 approaches are used to interpret climatic and environmental changes since the Pliocene in Spain : a study of species richness of 2 subfamilies of rodents (Murinae and Arvicolinae), an analysis of a faunal sequence with the cenogram
Here, the AA. report on plant macrofossil analyses for 3 late Pleistocene rodent middens associated with Dawson tephra at 2 sites in the Klondike gold fields of west-central Yukon Territory. The detail afforded by these middens permits

This paper presents a review of 4 infectious diseases found in the southwestern USA that are impacted by climate conditions. Hantavirus and plague are spread by rodents, dengue is transmitted through the bite of the Aedes mosquito
The feeding habits of two co-existing rodents, Rhabdomys pumilio (Sparrman, 1784) and Otomys irroratus Brants, 1827 in relation to rainfall and reproduction
