“…This has sparked a debate on the contribution of fishing to the overall diet for both the Paleo-Inuit 2 , Thule 25 and Norse 24 . One of the advantages of the BBM approach is the ability to detect DNA from small and fragile bones that cannot be identified morphologically 26,27 . In our data, this is exemplified by the detection of nine different fish species, of which, four species (Atlantic wolffish; Anarhichas lupus , lumpfish; Cyclopterus lumpus , redfish; Sebastes , American plaice; Hippoglossoides platessoides ) were not detected morphologically at any of the sites analysed.…”

The success and failure of past cultures across the Arctic was tightly coupled to the ability of past people to exploit the full range of resources available to them, and to adapt to fluctuations in resource availability. There is substantial evidence for the hunting of birds, caribou and a wide range of marine mammals in pre-historic Greenland from bone remains preserved in ancient middens. However, the extent to which these communities relied on marine resources such as fish and large cetaceans is understudied because of the taphonomic processes and bias that affect how these taxa present themselves in the archaeological record. To address this, we analyse DNA from bulk bone samples from 12 archaeological sites across Greenland dating from Paleo-Inuit to Neo-Inuit periods. Using a combination of metabarcoding and shotgun metagenomics we identify an assemblage of 43 species consisting of birds, fish, and both marine and terrestrial mammals. We find genetic evidence of five different whale species, of which the bowhead whale (Balaena mysticetus) was the most commonly detected. Furthermore, we detect nine fish species, of which four have not previously been identified in any of the studied sites. Lastly, we identify a novel haplotype in caribou (Rangifer tarandus) at the 3,000-year-old site Itinnera, suggesting the presence of a distinct lineage of (now extinct) dwarfed caribou that colonised Greenland after the last ice age 9,000 years ago. Collectively, these findings provide a rare insight into whaling and fishing practices in Greenland and demonstrate that prehistoric Greenlandic communities had the social and technological capacity to target the largest whales available in the waters around them.

“…a) Taxonomía: en los últimos años se ha obtenido material genético de fósiles, con impacto significativo tanto en taxonomía como en otros campos (e.g., filogeografía, paleodemografía). Su aplicación para pequeños mamíferos cuenta con escasos antecedentes en el Cuaternario de América del Sur (e.g., Tammone et al, 2018a;Seersholm et al, 2021). La calidad de preservación de los restos holocénicos de la región pampeana resulta una invitación para el desarrollo de este abordaje, cuya complejidad metodológica decrece paulatinamente.…”

Resumen. Se analiza la composición taxonómica cualitativa y cuantitativa de ensambles de micromamíferos (incluyendo didelfimorfos, quirópteros y roedores) generados por la acción trófica de aves estrigiformes. Estas muestras fueron coleccionadas en la localidad costera de Centinela del Mar (38° 26' 18,56" S; 58° 13' 17,42" O, General Alvarado, Buenos Aires, Argentina) y se escalonan, cronológicamente, para representar los últimos 500 años (i.e., Holoceno Tardío-Antropoceno). Desde aquella más antigua se registran la extinción local o regional de seis especies de roedores (i.e., Bibimys torresi, Ctenomys sp., Eligmodontia typus, Necromys lasiurus, Phyllotis sp. y Pseudoryzomys simplex) y la extinción biológica de un quiróptero (Desmodus draculae). En las muestras más recientes se verifica un incremento dramático del roedor Calomys sp. La comunidad de micromamíferos contemporánea es el resultado de la acción del impacto antrópico, en particular las actividades agrícolas de la última centuria actuando sobre un pool de especies pauperizado por los cambios climáticos del Holoceno Tardío (e.g., Óptimo Climático Medieval, Pequeña Edad del Hielo). Se discute la referencia previa de ensambles no-análogos para este tipo de asociaciones caracterizadas por la ocurrencia en simpatría de taxones actualmente alopátricos.

Although genetic diversity has been recognized as a key component of biodiversity since the first Convention on Biological Diversity (CBD) in 1993, it has rarely been included in conservation policies and regulations. Even less appreciated is the role that ancient and historical DNA (aDNA and hDNA, respectively) could play in unlocking the temporal dimension of genetic diversity, allowing key conservation issues to be resolved, including setting baselines for intraspecies genetic diversity, estimating changes in effective population size (N e) , and identifying the genealogical continuity of populations. Here, we discuss how genetic information from ancient and historical specimens can play a central role in preserving biodiversity and highlight specific conservation policies that could incorporate such data to help countries meet their CBD obligations. Genetic biodiversityThree levels of biodiversity constitute the variation of life on our planet: diversity of ecosystems, species diversity (number and distribution of species), and genetic diversity (amount and distribution of genetic variation within species or populations). The need to monitor biodiversity at all three levels has been globally recognized in international policy since 1993 when the Convention on Biological Diversity i (CBD) came into effect. Today, we face dramatic biodiversity loss due to the combined effects of habitat damage, fragmentation and alteration, climate change, and other global change stressors. Most frequently, this loss is calculated in terms of the number of species, but relatively little is known about loss of diversity within species and populations at the genome level (but see [1]). Genetic diversity within species and populations is necessary for long-term survival as it allows resilience and adaptation not only for individuals, but also for populations, species, and entire ecosystems [2]. This diversity is particularly relevant in the Anthropocene, characterized by significant, rapid, and global changes to habitats and environmental conditions. Despite the importance of genetic diversity in biodiversity protection and management, it has rarely been included in policies and regulations [3]. But, with the ongoing development of the CBD post-2020 Global Biodiversity Framework (expected to be concluded in May 2022), there is an opportunity to address this significant blind spot by adopting genetic diversity targets and indicators.
