RDAforest: Identifying Environmental Drivers of Polygenic Adaptation

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Identifying environmental gradients driving genetic adaptation is one of the major goals of ecological genomics. We present RDAforest, a methodology that leverages the predominantly polygenic nature of adaptation and harnesses the versatility of random forest regression to solve this problem.

Using synthetic farm data to estimate individual nitrate leaching levels

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This article delineates a synthetic population generation scheme in an attempt to estimate individual nitrate leaching rates among Greek farms in the region of Thessaly. The proposed scheme relies upon the construction of a Bayesian network describing farming activities in the region, which, coupled with the use of nonparametric regression ...

Left to Live and Die: Resource Security and the Biopolitics of Land Stockpiling in China

open access: yesAntipode, EarlyView.
Abstract Beginning in 2007, the Chinese state used liberalising policy and funding to encourage the expansion of large‐scale grain farming. Despite this support, many of the new farms have struggled financially and folded. Drawing on Foucauldian biopolitics and resource security literature, I argue that, with modernised agriculture, the state primarily

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

open access: yesAntipode, EarlyView.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...
