Sclerochronological analysis of shell midden faunal remains offers a unique opportunity to
study climate and environmental change in relation to human activity. Middens exist near …

This paper reviews recently published literature, most of which was published in Chinese,
and searches for regional patterns of Holocene changes useful in depicting global patterns …

Resistance genes (R-genes) act as an immune system in plants by recognizing pathogens
and inducing defensive pathways. Many R-gene loci are present in plant genomes …

Naturally occurring variations in the stable isotope composition of fossil vertebrates have
been studied since the late 1970s. Isotopic data from vertebrate fossils are sometimes used …

We report a quantitative analysis of regional differences in the the oxygen isotope
composition of river water and precipitation across the USA because data are now available …

Anthropogenic impacts have shifted aquatic ecosystems far from prehistoric baseline states;
yet, understanding these impacts is impeded by a lack of available long-term data that …

Ecological research using stable isotopes has progressed rapidly during the last 20 years
and although more studies are including the addition of isotopically labelled compounds at …

The accurate identification of fish 'ear-bones', known as otoliths, is essential to determine the
fish prey of marine and terrestrial predators. Fish otoliths are species-specific when …

Otoliths are small structures found in the inner ear of teleost fish that act as organs of
equilibrium and as direction and sound detectors. They possess unique characteristics that …

Archaeological evidence suggests that southwest Florida experienced variably warmer and
wetter climate during the Roman Warm Period (RWP; 300 BC–550 AD) relative to the …
