Flanders’ Riverine Exploitation and ecoSystems throughout History

Over the centuries, Flanders’ rivers have undergone dramatic changes. In this project, changes in freshwater fish exploitation and ecosystem health during the medieval and postmedieval periods in relation to socioeconomic and human-induced environmental changes in Flanders will be investigated by combining archaeological, ecological and historical data.

COASTAL TALES

Telling Adaptations; Living Environmental Stories for Coastal Resilience

The project’s aim is to show how heritage stories can generate tangible local action that diverse communities can draw on and be inspired by to adapt to a changing climate sustainably. Researchers and Project Partners in Dublin (Ireland), several locations in Wales, and on Kodiak, Alaska (USA) are working with local community members, heritage entrepreneurs and NGOs to study and support the use of storytelling and other forms of heritage knowledge about coastal and nearshore marine environments to facilitate resilience of coastal communities into the future.

JAWS

Japanese Archaeology of WhaleS

The gray whale (Eschrichtius robustus) and the North Pacific right whale (Eubalaena japonica) populations in the western North Pacific are both endangered. By applying zooarchaeological, palaeoproteomic, and stable isotope analysis on archaeological cetacean remains from the sites of Kafakai 1 and Onkoromanai (northern Hokkaido), JAWS assesses whether the species were previously hunted in the area and determines the past foraging niches of the different species, potentially useful to modern conservation efforts protecting these iconic animals.

DAG

Demise of the Atlantic Grey whale

The gray whale (Eschrichtius robustus) is currently confined to the North Pacific, but archaeological and palaeontological evidence revealed the species was once also present in the North Atlantic, making it the only large whale species to been extirpated from an entire ocean in historical times. By applying zooarchaeological, palaeoproteomic, stable isotope, and aDNA analysis, DAG attempts to reconstruct the historical ecology of the gray whale in European waters, assess when the species disappeared, and whether this was directly caused by anthropogenic activities.

Short-term and extreme climates causing agricultural risks on the cusp of the Neolithic transition

This project reconstructs seasonal climatic conditions directly experienced by early Mediterranean farmers in the early to middle holocene using high-resolution sclerochronology on mollusc shells from archaeological layers. By bridging the gap between local weather and broader climate archives, it reassesses environmental impacts on the Neolithic Dispersal.

Untangling the long co-evolution of herring and people along the Pacific Rim

With fieldwork based in Hokkaido, Japan and Sitka Sound, Alaska, this project is aimed to assess the consequences of shifting management regimes for the Pacific herring from Indigenous stewardship to industrial fishing over the past several hundred years using ancient DNA and historical ecology. This work is being conducted in partnership with local representatives in Hokkaido and the Sitka Tribe of Alaska.
