Transformation of Lactiplantibacillus plantarum and Apilactobacillus kunkeei is influenced by recipient cell growth temperature, vector replicon, and DNA methylation.

The effects of recipient cell growth temperature, vector choice, and DNA methylation on transformation efficiency were explored for Lactiplantibacillus plantarum strain B38 and Apilactobacillus kunkeei strains YH15 and 3L. All three parameters significantly affected transformation efficiency. L.

Archaeological assessment reveals Earth's early transformation through land use.

Environmentally transformative human use of land accelerated with the emergence of agriculture, but the extent, trajectory, and implications of these early changes are not well understood. An empirical global assessment of land use from 10,000 years before the present (yr B.P.

Revisiting traumatic injury risk and agricultural intensification: Postcranial fracture frequency at Cerro Oreja in the Moche Valley of north coastal Peru.

Objectives: In Lambert and Welker (2017) we explored the association between subsistence economy and postcranial fracture prevalence, finding that low-intensity agriculturalists exhibited significantly lower fracture rates than foragers or high-intensity agriculturalists. Here, we explore the impacts of sampling strategy on fracture rates in a sample of high-intensity agriculturalists from the Moche Valley, Peru, and further test the hypothesis that postcranial fracture risks are higher for intensive agriculture.

Materials And Methods: The long bones and clavicles of 102 individuals from an Early Intermediate Period cemetery (400 B.

Traumatic injury risk and agricultural transitions: A view from the American Southeast and beyond.

Objectives: Bioarchaeological research has documented a general decline in health with the transition from foraging to farming, primarily with respect to changing patterns of morbidity. Less is known about changes in injury risk, an aspect of health more obviously tied to particular landscapes and behaviors associated with different subsistence regimes. The purpose of this research is to evaluate several hypotheses emerging from the ideal free distribution model (Fretwell & Lucas, ) that predict injury risk based on subsistence-specific practices and land use patterns.
