Molecular Characterization and mRNA Expression of Cytochrome P450 1A1 and Cytochrome P450 3A in Liver of Kafue Lechwe (<i>Kobus leche kafuensis</i>) as Potential Biomarkers of Pollution of the Kafue River Basin, Zambia

open access: yesEngineering, 2014
The aim of this study was to characterize CYP1A1 and CYP3A in liver of the Kafue lechwe from Lochnivar and Blue Lagoon GMAs and to determine their mRNA expression levels as potential biomarkers of pollution. Increasing attention is paid to the problem of pesticide pollution by people.

Climate-linked temporal and spatial patterns in the evolution of African bovidae [PDF]

open access: yes, 2012
Climate and subsequent environmental changes are regarded as one driver of species evolution. Against this background the present study investigates the evolutionary history of the mammalian family Bovidae (Cetartiodactyla, Mammalia), today the most ...

Dental Microwear Texture Analysis of Pliocene Bovids from Four Early Hominin Sites in Eastern Africa: Implications for Paleoenvironmental Dynamics and Human Evolution [PDF]

open access: yes, 2012
Many researchers have suggested that Plio-Pleistocene climate change was a motive force for human evolution. The basic idea was that a shift toward drier, more open settings, led to adaptations for bipedality and the consumption of savanna resources ...
