Abstract The archaeology of the pre-contact Andes provides an ideal study human responses to climate change given region's extreme climatic variability, excellent archaeological preservation, and robust paleoclimate records. We evaluate effects on frequency interpersonal violence in south-central from ca. 1.5–0.5 ka (AD 470–1540) by comparing incidents skeletal trauma observed among 2753 crania...

Potato yields in sub-Saharan Africa remain very low compared with those of developed countries. Yet potato is major food staple and source of income to the predominantly smallholder growing households in the tropical highlands of this region. A major cause of the low potato yields is the use of poor quality seed potato. This paper examines the factors determining the decision to use certified s...
Granitic rocks related to 1.18 to 1.13 Ga anorthosite-mangerite-charnockitegranite plutonism stitch three terranes in the southwestern Grenville Province (Adirondack Highlands–Morin terrane, Frontenac terrane, Elzevir terrane). Because of the refractory nature of zircon (Zrn), analysis of oxygen-isotope ratios of dated igneous zircon from these rocks allows calculation of δ18O values of origina...
The influence of riverine barriers on phylogeographic patterns of Malagasy reed frogs (Heterixalus).
We analyzed the influence of large rivers on the phylogeography of endemic widespread amphibians along Madagascar's east coast, using as models various species and species complexes of Malagasy reed frogs (Heterixalus spp.) that are specialized to either highland or lowland habitats. We assembled a dense sampling across the full species ranges and used mitochondrial (cob) as well as nuclear (Ra...
