“…Nonetheless, most ancient mtDNA studies have focused on terrestrial species, and studies that investigate the impacts of long-term human activities and/or climatic variation on fish, using whole genome sequencing approaches, are relatively rare. Long-term commercial fisheries-covering many centuries-have contributed to the decline of economically and ecologically important marine species (Exadactylos et al, 2007;Pinnegar and Engelhard, 2008;Barrett, 2019). The consequences of intensive fishing in recent times may be difficult to assess as this requires an understanding of historical population dynamics (Selim et al, 2016).…”

Ancient DNA (aDNA) approaches have been successfully used to infer the long-term impacts of climate change, domestication, and human exploitation in a range of terrestrial species. Nonetheless, studies investigating such impacts using aDNA in marine species are rare. Atlantic cod (Gadus morhua), is an economically important species that has experienced dramatic census population declines during the last century. Here, we investigated 48 ancient mitogenomes from historical specimens obtained from a range of archeological excavations in northern Europe dated up to 6,500 BCE. We compare these mitogenomes to those of 496 modern conspecifics sampled across the North Atlantic Ocean and adjacent seas. Our results confirm earlier observations of high levels of mitogenomic variation and a lack of mutation-drift equilibrium—suggestive of population expansion. Furthermore, our temporal comparison yields no evidence of measurable mitogenomic changes through time. Instead, our results indicate that mitogenomic variation in Atlantic cod reflects past demographic processes driven by major historical events (such as oscillations in sea level) and subsequent gene flow rather than contemporary fluctuations in stock abundance. Our results indicate that historical and contemporaneous anthropogenic pressures such as commercial fisheries have had little impact on mitogenomic diversity in a wide-spread marine species with high gene flow such as Atlantic cod. These observations do not contradict evidence that overfishing has had negative consequences for the abundance of Atlantic cod and the importance of genetic variation in implementing conservation strategies. Instead, these observations imply that any measures toward the demographic recovery of Atlantic cod in the eastern Atlantic, will not be constrained by recent loss of historical mitogenomic variation.

“…Only a limited number of fish aDNA studies have been published, despite their environmental and economic importance, and the abundance of archaeological fish bone (Barrett, 2019; Oosting et al, 2019). Especially whole genome HTS approaches (e.g., Star et al, 2017) focusing on fish remains are rare.…”

40The field of ancient DNA is taxonomically dominated by studies focusing on mammals. This 41 taxonomic bias limits our understanding of endogenous DNA preservation for vertebrate taxa 42 with different bone physiology, such as teleost fish. In contrast to most mammalian bone, teleost 43 bone is typically brittle, porous, lightweight and is characterized by a lack of bone remodeling 44 during growth. Using high-throughput shotgun sequencing, we here investigate the preservation 45 of DNA in a range of different bone elements from over 200 archaeological Atlantic cod (Gadus 46 morhua) specimens from 38 sites in northern Europe, dating up to 8000 years before present. We 47 observe that the majority of archaeological sites (79%) yield endogenous DNA, with 40% of sites 48 providing samples that contain high levels (> 20%). Library preparation success and levels of 49 endogenous DNA depend mainly on excavation site and pre-extraction laboratory treatment. The 50 use of pre-extraction treatments lowers the rate of library success, although -if successful -the 51 fraction of endogenous DNA can be improved by several orders of magnitude. This trade-off 52 between library preparation success and levels of endogenous DNA allows for alternative 53 extraction strategies depending on the requirements of down-stream analyses and research 54 questions. Finally, we find that -in contrast to mammalian bones -different fish bone elements 55 yield similar levels of endogenous DNA. Our results highlight the overall suitability of 56 archaeological fish bone as a source for ancient DNA and provide novel evidence for a possible 57 role of bone remodeling in the preservation of endogenous DNA across different classes of 58 vertebrates. 59 60 Dabney et al., 2013), with the inclusion of a pre-digestion step (DD, Damgaard et al., 2015), or with 129

Resumo: Este artigo apresenta a linguagem da pesca, de acordo com os dicionários Tesoro e Vocabulario de la lengua Guaraní, publicados entre 1639 e 1640, pelo missionário jesuíta Antonio Ruiz de Montoya. Destaca-se também um caso de armadilhas de pesca arqueológicas no rio Ivaí, Estado do Paraná, Brasil. Foram selecionadas 335 palavras e frases para algumas descrições e para compor cenários etnográficos. O objetivo é mostrar que a pesca era estruturada por um sistema de conhecimentos ecológicos tradicionais dos Guaraní, com grande persistência de práticas e adaptabilidades em uma vasta região. O léxico apresenta grande potencial para orientar a compreensão das práticas pesqueiras no entorno dos sítios etnográficos e arqueológicos, assim como para contribuir com estudos histórico-comparativos de línguas do tronco Tupí.Abstract: This article presents the language of fishing according to the Tesoro and Vocabulario de la lengua Guaraní, published between 1639 and 1640, by the Jesuit missionary Antonio Ruiz de Montoya.

The objective is to show that fishing was structured by a system of Guaraní traditional ecological knowledge, with great persistence of practices and adaptability in a vast region. The lexicon has great potential to guide the understanding of fishing practices around ethnographic and archaeological sites, as well as to contribute to historicalcomparative studies on languages of the Tupí stock.Piratýpe: uma linguagem da pesca e do consumo de peixes entre os Guaraní
