“…These approaches include stable isotope analysis, proteomics, and genomics, often in conjunction with archeology and paleontology to form the discipline of biomolecular archaeo/paleontology. The research aims that can be addressed include: species identification (Biard et al, 2017); establishing trade, migration, and population continuity (Star et al, 2017); reconstructing demographic history and evolutionary change (De Bruyn et al, 2009;Foote et al, 2013); and analyzing past ecological and climatic conditions (Gokhman et al, 2017). Recent advances in ancient biomolecular techniques have created a novel arena for investigating thresholds, one that is already beginning to take shape in bioarchaeology and marine ecology (Martínez-García et al, 2021;Ólafsdóttir et al, 2021).…”

Current research on anthropogenic impacts on marine ecosystems often relies on the concept of a “baseline,” which aims to describe ecosystems prior to human contact. Recent research is increasingly showing that humans have been involved in marine ecosystems for much longer than previously understood. We propose a theoretical framework oriented around a system of “thresholds” referring to system-wide changes in human culture, ecosystem dynamics, and molecular evolution. The concept of the threshold allows conceptual space to account for the fluid nature of ecosystems throughout time while providing a critical framework for understanding drivers of ecosystem change. We highlight practical research approaches for exploring thresholds in the past and provide key insights for future adaptation to a changing world. To ensure ecological and societal goals for the future are met, it is critical that research efforts are contextualized into a framework that incorporates human society as integral to ecology and evolution.

“…Although the mitogenomes from two ancient D. delphis individuals (Biard et al. 2017 ) were the most similar to CRI007520 with 99.6% each, the highest species-specific OrthoANI value was obtained for Stenellacoeruleoalba (NC_012053, 98.3%), whereas the lowest was for killer whale ( Orcinus orca ; NC_023889, 93.0%).…”

“…At present, D. delphis is listed in Appendix II of the Convention on International Trade in Endangered Species (CITES 2014) and has been listed as 'Least Concern' by the International Union for Conservation of Nature and Natural Resources Red List of Threatened Species (Hammond et al 2008). A recent study revealed several mitogenomes of ancient D. delphis individuals excavated in the Black sea (Biard et al 2017); however, the mitogenomes from existing individuals have not yet been reported. We report the complete mitogenome of an existing D. delphis individual.…”

The timing of the Holocene transition of the Black Sea from a brackish lake to a marine sea has long been debated. Here, we report on the earliest records of cetaceans in the Black Sea region as a proxy for the connection with the Mediterranean and the transition from a brackish to marine environment. We base our analysis on cetacean skeletal finds and archival data on cetacean skeletal remains from the Bosphorus, the western, northern and eastern Black Sea, and the Kerch Strait. We find that all three contemporary cetacean species in the Black Sea – the harbour porpoise, bottlenose dolphin and common dolphin – had migrated out of the Mediterranean to the Bosphorus and the Black Sea at least 8000–7000 years ago and reached the northern Black Sea by 5500 years ago at the latest. Our study suggests the establishment of a Mediterranean–Black Sea biogeographical connection for marine vertebrates at least 7000 years ago. The early presence of cetaceans in the Black Sea has implications for understanding its Holocene transition, as well as the evolutionary and ecological history of these species more generally.
