The isotope ratios of zinc ( 66 Zn/ 64 Zn expressed as δ 66 Zn), a vital nutrient, increasingly demonstrate trophic discrimination among vertebrates, making δ 66 Zn a valuable dietary proxy for ecological, archaeological, and palaeontological studies. Given the novelty of the methodology, tissue-diet and tissue-tissue zinc isotope fractionation factors remain poorly understood and have so far only been studied in a few terrest...
Combining collagen extraction with mineral Zn isotope analyses from a single sample for robust palaeoecological investigationsNARA Subscribed
Collagen extraction from bones or dentine, commonly used for radiocarbon ( 14 C) dating and stable carbon and nitrogen isotope (δ 13 C and δ 15 N) analyses, involves the dissolution of the bioapatite of skeletal elements. This fraction is typically disposed of during pretreatment. Here, we test the possibility of utilising this dissolved mineral solution for analysis of the bioapatite zinc isotope composition (δ 66 Zn). Bioapa...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
