The Diffusion of Humans and Cultures in the Course of the Spread of Farming

, 2017
The most profound change in the relationship between humans and their environment was the introduction of agriculture and pastoralism. [....] For an understanding of the expansion process, it appears appropriate to apply a diffusive model. Broadly, these

Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

Boreas, EarlyView.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.

A Framework to Investigate the Effects of Observation Error on Neural Network Predictions of Fish Age

Fish and Fisheries, EarlyView.
ABSTRACT Technological innovations for predicting fish age represent a paradigm shift from conventional age estimation methods used in fisheries science. Recently developed secondary methods rely on models trained on conventional age estimates, derived from subjective interpretation of growth patterns and a biological property of the fish to predict ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

Journal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, EarlyView.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.
