Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya

American Anthropologist, EarlyView.
ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.

Dealing With Inbuilt Age: A Bayesian Approach to Radiocarbon Dating of Rice, Bamboo and Charcoal From Non Ban Jak, Thailand

Archaeometry, EarlyView.
ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

The distribution of pond snail communities across a landscape: separating out the influence of spatial position from local habitat quality for ponds in south-east Northumberland, UK [PDF]

, 2009
Ponds support a rich biodiversity because the heterogeneity of individual ponds creates, at the landscape scale, a diversity of habitats for wildlife. The distribution of pond animals and plants will be influenced by both the local conditions within a ...
