Collagen fingerprinting of Caribbean archaeological fish bones: Methodological implications for historical fisheries baselines and anthropogenic change

چکیده
The Caribbean Sea is the most species-rich sea in Atlantic, largely due to its vast coral reef systems. However, high biodiversity and endemism face unprecedented anthropogenic threats, including synergistic modern pressures from overfishing, climate change bioinvasion. Archaeological data indicate initial human settlement of ∼7000 years before present (yr BP), with regionally variable impacts on fisheries through time based standard morphological identification fish bone. Such studies, however, are challenged by low taxonomic resolution archaeological bone identifications species diversity similarity between members different families or genera. Here, we collagen fingerprinting (Zooarchaeology Mass Spectrometry; ZooMS) as a method overcome this challenge, applying it 1000 specimens identified morphologically ray-finned (superclass Actinopterygii) 13 circum-Caribbean sites spanning ca. 3150–300 yr BP (years present). successfully collagen-containing samples (n = 720) family (21%), genus (57%), (13%) level. Of 209 that were below superclass, verified identity 94% these, but also refined lower [more precise] taxon 45% cases. remaining 6% found be incorrectly assigned. This study represents largest application ZooMS bones date advances future research up 20 biomarkers for 45 taxa 10 2 orders. results refinement limited not quality preserved extent available reference collection. Thus, efforts should directed towards expanding fingerprint databases first instance. Significantly, high-resolution can offer make ancient highly relevant sustainability conservation Caribbean.

متن کاملAnalysis of collagen preservation in bones recovered in archaeological contexts using NIR Hyperspectral Imaging.
The scope of this article is to propose an innovative method based on Near Infrared Hyperspectral Chemical Imaging (NIR-HCI) to rapidly and non-destructively evaluate the relative degree of collagen preservation in bones recovered from archaeological contexts. This preliminary study has allowed the evaluation of the potential of the method using bone samples from the Early Upper Palaeolithic, M...
متن کاملShifting baselines and the extinction of the Caribbean monk seal.
The recent extinction of the Caribbean monk seal Monachus tropicalis has been considered an example of a human-caused extinction in the marine environment, and this species was considered a driver of the changes that have occurred in the structure of Caribbean coral reef ecosystems since colonial times. I searched archaeological records, historical data, and geographic names (used as a proxy of...
متن کاملGeophysical, archaeological, and historical evidence support a solar-output model for climate change.
Although the processes of climate change are not completely understood, an important causal candidate is variation in total solar output. Reported cycles in various climate-proxy data show a tendency to emulate a fundamental harmonic sequence of a basic solar-cycle length (11 years) multiplied by 2(N) (where N equals a positive or negative integer). A simple additive model for total solar-outpu...
