Abstract: The cultural and spiritual significance of nature has been defined as the spiritual, cultural, inspirational, aesthetic, historic and social meanings, values, feelings, ideas and associations that natural features and nature in general have for past, present and future generations of people – both in iduals and groups. These guidelines respond to a growing need to make conservation more inclusive, effective and socially just by accommodating multiple worldviews by treating natural and cultural heritage as interlinked and by suggesting ways for engaging and empowering all relevant groups and stakeholders in protected area design, governance and management. The guidelines also assist with creating common ground, resolving conflicts and implementing rights-based approaches that recognise human rights and legal pluralism.

Abstract: The factors underlying gene flow and genomic population structure in vagile seabirds are notoriously difficult to understand due to their complex ecology with erse dispersal barriers and extensive periods at sea. Yet, such understanding is vital for conservation management of seabirds that are globally declining at alarming rates. Here, we elucidate the population structure of the Atlantic puffin ( Fratercula arctica ) by assembling its reference genome and analyzing genome-wide resequencing data of 72 in iduals from 12 colonies. We identify four large, genetically distinct clusters, observe isolation-by-distance between colonies within these clusters, and obtain evidence for a secondary contact zone. These observations disagree with the current taxonomy, and show that a complex set of contemporary biotic factors impede gene flow over different spatial scales. Our results highlight the power of whole genome data to reveal unexpected population structure in vagile marine seabirds and its value for seabird taxonomy, evolution and conservation.

Abstract: The majority of archaeological plant material is preserved in a charred state. Obtaining reliable ancient DNA data from these remains has presented challenges due to high rates of nucleotide damage, short DNA fragment lengths, low endogenous DNA content and the potential for modern contamination. It has been suggested that high-throughput sequencing (HTS) technologies coupled with DNA enrichment techniques may overcome some of these limitations. Here we report the findings of HTS and target enrichment on four important archaeological crops (barley, grape, maize and rice) performed in three different laboratories, presenting the largest HTS assessment of charred archaeobotanical specimens to date. Rigorous analysis of our data – excluding false-positives due to background contamination or incorrect index assignments – indicated a lack of endogenous DNA in nearly all s les, except for one lightly-charred maize cob. Even with target enrichment, this s le failed to yield adequate data required to address fundamental questions in archaeology and biology. We further reanalysed part of an existing dataset on charred plant material, and found all purported endogenous DNA sequences were likely to be spurious. We suggest these technologies are not suitable for use with charred archaeobotanicals and urge great caution when interpreting data obtained by HTS of these remains.

Abstract: The feasibility of genome-scale studies from archaeological material remains critically dependent on the ability to access endogenous, authentic DNA. In the majority of cases, this represents a few per cent of the DNA extract, at most. A number of specific pre-extraction protocols for bone powder aimed to improve ancient DNA recovery before library lification have recently been developed. Here, we test the effects of combining two of such protocols, a bleach wash and a predigestion step, on 12 bone s les of Atlantic cod and domestic horse aged 750-1350 cal. years before present. Using high-throughput sequencing, we show that combined together, bleach wash and predigestion consistently yield DNA libraries with higher endogenous content than either of these methods alone. Additionally, the molecular complexity of these libraries is improved and endogenous DNA templates show larger size distributions. Other library characteristics, such as DNA damage profiles or the composition of microbial communities, are little affected by the pre-extraction protocols. Application of the combined protocol presented in this study will facilitate the genetic analysis of an increasing number of ancient remains and will reduce the cost of whole-genome sequencing.

Abstract: Glacial cycles play important roles in determining the phylogeographic structure of terrestrial species, however, relatively little is known about their impacts on the distribution of marine biota. This study utilised modern ( n = 350) and ancient ( n = 26) mitochondrial genomes from Australasian snapper ( Chrysophrys auratus ) s led in New Zealand to assess their demographic and phylogeographic history. We also tested for changes in genetic ersity using the up to 750-year-old mitochondrial genomes from pre-European archaeological sites to assess the potential impacts of human exploitation. Nucleotide ersity and haplotype ersity was high (π = 0.005, h = 0.972). There was no significant change in nucleotide ersity over the last 750 years ( p = 0.343), with no detectable loss of ersity as a result of indigenous and industrial-scale fishing activity. While there was no evidence for contemporary population structure (AMOVA, p = 0.764), phylogeographic analyses identified two distinct mitochondrial clades that erged approximately 650,000 years ago during the mid-Pleistocene, suggesting the species experienced barriers to gene flow when sea levels dropped over 120 m during previous glacial maxima. An exponential population increase was also observed around 8000 years ago consistent with a post-glacial expansion, which was likely facilitated by increased ocean temperatures and rising sea levels. This study demonstrates that glacial cycles likely played an important role in the demographic history of C. auratus and adds to our growing understanding of how dynamic climatic changes have influenced the evolution of coastal marine species.

Abstract: Historic museum specimens are increasingly used to answer a wide variety of questions in scientific research. Nevertheless, the scientific value of these specimens depends on the authenticity of the data associated with them. Here we use in idual-based genetic analyses to demonstrate erroneous locality information for archive specimens from the late nineteenth century. Specifically, using 10 microsatellite markers, we analysed 350 contemporary and 43 historic yellow-eyed penguin ( Megadyptes antipodes ) specimens from New Zealand's South Island and sub-Antarctic regions. Factorial correspondence analysis and an assignment test strongly suggest that eight of the historic specimens purportedly of sub-Antarctic origin were in fact collected from the South Island. Interestingly, all eight specimens were obtained by the same collector, and all are currently held in the same museum collection. Further inspection of the specimen labels and evaluation of sub-Antarctic voyages did not reveal whether the erroneous data are caused by incorrect labelling or whether deliberate falsification was at play. This study highlights a promising extension to the well-known applications of assignment tests in molecular ecology, which can complement methods that are currently being applied for error detection in specimen data. Our results also serve as a warning to all who use archive specimens to invest time in the verification of collection information.

Abstract: Across its range, the Atlantic Puffin Fratercula arctica is ided into four separate genetic clusters that correspond with geography and/or size differences. However, in the Western Atlantic High Arctic, there is a Puffin colony (Thule) that comprises two discrete size phenotypes. Using whole genome sequencing data of six Thule in iduals from these two phenotypes, we found that Thule consists of three distinct genetic clusters, with no signs of recent interbreeding. Our results suggest the beginnings of a potential northward shift of boreal Atlantic Puffins in the West Atlantic, consistent with responses to a warming High Arctic climate.

Abstract: A rich archaeological record of fish-bone remains testifies to the millennia-long human exploitation of the natural resources of the oceans. In Europe, historical evidence demonstrates that an extensive international industry developed during the Middle Ages that exported preserved cod from the Lofoten Archipelago, northern Norway, to expanding urban centers around the North and Baltic Sea regions. The early origins of this iconic exchange, however, have long been debated. We genetically trace the ancestry of Viking Age fish from mainland Europe to the North East Arctic cod population that supports the modern Lofoten fisheries. This application of genome-wide analyses from ancient fish bone reveals an early origin of what became an economically important trade, with implications for archaeology and environmental history.
