The waterscape, including the sea, rivers, and lakes, was highly important to communities living during the Nordic Early Bronze Age (1800/1700–1100 bc). Waterways acted as highways that facilitated journeys, trade, and warfare, enabling maritime warriors and others to distinguish themselves. This is reflected in the maritime location of rock art and important Early Bronze Age burials, which have been used to reconstruct the Nordic Bronze Age cosmology. This centres on the journey of the sun across the sky during the day, and the underworld during night. This article analyses the use of water-related resources, such as seaweed, petrified organics, beach pebbles, and molluscs, in the construction of burials, which has received little attention despite renewed interest in the maritime seascape. The data demonstrate that local communities used different resources, indicating that a common belief system was realised in local differences. These marine materials were collected from the beach, which can be conceptualised as the liminal zone between the land of the living and the sea of the dead. It is suggested that these materials, in line with other funerary practices, helped to guide the recently deceased into the afterlife in the sea.

We present stable isotope and osteological data from human remains at Paloma, Chilca I, La Yerba III, and Morro I that offer new evidence for diet, lifestyle, and habitual mobility in the first villages that proliferated along the arid Pacific coast of South America (ca. 6000 cal BP). The data not only reaffirm the dietary primacy of marine protein for this period but also show evidence at Paloma of direct access interactions between the coast and highlands, as well as habitual mobility in some parts of society. By locating themselves at the confluence of diverse coastal and terrestrial habitats, the inhabitants of these early villages were able to broaden their use of resources through rounds of seasonal mobility, while simultaneously increasing residential sedentism. Yet they paid little substantial health penalty for their settled lifestyles, as reflected in their osteological markers of stature and stress, compared with their agriculturalist successors even up to five millennia later. Contrasting data for the north coast of Chile indicate locally contingent differences. Considering these data in a wider chronological context contributes to understanding how increasing sedentism and population density laid the foundations here for the emergence of Late Preceramic social complexity.

Marine gastropods are consumed worldwide due to their nutritional quality, having important economic value in international markets. In the gulfs of Northern Patagonia (Argentina), marine gastropods are captured as complementary resources during bivalve artisanal fisheries. In this study, we determined the biochemical composition during the reproductive cycle of four edible marine gastropods abundant along the South-western Atlantic coast: Odontocymbiola magellanica, Buccinanops deformis, Buccinanops cochlidium and Trophon geversianus. All the studied species presented high protein (36–70.8%), low lipids (0.02–1.50%) and intermediate glycogen content (3.22–14.08%). The main oviposition season was during spring and summer. The mean nutritional values indicate that the species studied provide a good source of nutrients appropriate to the human diet, reaffirming their value as a commercial resource. Taking into account the nutritional contribution and the reproductive season, the best period for the capture of these resources is during summer for O. magellanica and T. geversianus, and during autumn for B. deformis and B. cochlidium. This work will help promote the consumption of Patagonian gastropods while ensuring their responsible capture, contributing to the sustainability of these valuable resources.

Edible marine gastropods are consumed in northern Patagonia without regulations or knowledge of nutritional composition and food quality. We determined total lipids (TL), fatty acid (FA), paralytic shellfish poison (PSP) and metal contamination in six edible marine gastropods: Buccinanops globulosus, B. cochlidium, Trophon geversianus, Odontocymbiola magellanica, Tegula patagonica and Nacella magellanica. TL was lowest in the foot (0.29–0.56%) and maximum in organs (1.43–3.2%), presenting less TL than other edible species around the world. Saturated FA were similar to other consumed marine gastropods worldwide and dominant in all species studied (33.26–48.19%), while monounsaturated FA reached about 30% only in 2 species, but did not exceed 18% in the other species. Polyunsaturated FA reached up to 23.77%, but generally did not exceed 14%. Highly unsaturated FA (AA, EPA and DHA), reached about 27%. The dominant FA was palmitic acid (0.217 to 2.43 µg mg−1).Differences in FA could be related to the different alimentation of the species. Limit of PSP consumption was exceeded in a few months only for two species. Lead was not detectable (<4 µg g−1) while cadmium ranged from 0.07 to 15.32 µg g−1. Our results can be useful to ensure the safety food of these resources, which are being consumed and exported in low quantities in Argentina, but may be commercialized massively in the near future. Monitoring these and other food resources is essential and should be performed in any established fishery of the species reported here to guarantee the safety human consumption.

Representations and remains of sharks are found in Mesoamerican art and archaeology from the first millennium BC onwards. They appear at coastal sites, but also remarkably far inland, hundreds of kilometres from the waters where they were sighted or hunted. For the Maya of the interior of the Yucatán Peninsula, encounters with live sharks would have been an exceedingly rare occurrence. Yet the animals arrived inland in piecemeal fashion—as chunks of meat and sets of teeth—and via stories. By following the procurement, transportation, representation and ritual use of sharks from the sea to the jungle, the author shows how the ancient Maya drew on both evidence and myth to imagine and explain these unfamiliar marine creatures.

This work provides new insights into human responses to and perceptions of sea-level rise at a time when the landscapes of north-west Europe were radically changing. These issues are investigated through a case study focused on the Channel Islands. We report on the excavation of two sites, Canal du Squez in Jersey and Lihou (GU582) in Guernsey, and the study of museum collections across the Channel Islands. We argue that people were drawn to this area as a result of the dynamic environmental processes occurring and the opportunities these created. The evidence suggests that the area was a particular focus during the Middle Mesolithic, when Guernsey and Alderney were already islands and while Jersey was a peninsula of northern France. Insularisation does not appear to have created a barrier to occupation during either the Middle or Final Mesolithic, indicating the appearance of lifeways increasingly focused on maritime voyaging and marine resources from the second half of the 9th millennium BC onwards.

The challenge to manage coastal resources within Asia-Pacific's Coral Triangle has gained global attention. Co-management is promoted as a key strategy to address this challenge. Contemporary community-based co-management often leads to ‘hybridization’ between local (customary) practices, and science-based management and conservation. However, the form of this hybrid has rarely been critically analysed. This paper presents examples of co-management practices in eastern Indonesia and Solomon Islands, focusing in particular on area closures. In contrast to the temporary closures used before the influx of sustainability discourses, contemporary closures are periodically-harvested but predominantly closed, reflecting attempts to reduce fishing effort and enhance ecological sustainability. When areas are opened, harvests are relatively short and largely triggered by the social and economic needs of particular individuals or whole communities. In all cases, engagement with environmental management interventions has led to more formalized access and use arrangements. The harvesting and management practices observed are influenced by these relatively recent interventions designed to promote sustainability, but also by religious institutions, increasing resource demand, and modernization. This study unpacks some of the contemporary influences, particularly environmental sustainability initiatives, on local management practices, and provides insights for co-management in practice.

Models of the Mesolithic–Neolithic transition in Britain in recent years have tended to downplay the role of changes in the subsistence economy, emphasizing a very gradual adoption of new domesticated resources. This view has been particularly pervasive for the west coast of Scotland, which in the context of Britain presents a relatively marginal environment for farming. In this article, we challenge this too-quickly emerging orthodoxy through the presentation and discussion of both new and previously published stable isotope data and AMS dates. The palaeodietary information, while limited, strongly suggests a very rapid and complete change in the subsistence economy coincident with the earliest manifestations of the Neolithic on the west coast of Scotland early in the fourth millennium cal. BC. Whatever explanation is invoked to account for the transition needs to engage with the isotopic data. The possibility of colonization at some level needs to be seriously reconsidered.
