Archaeological and Biogeochemical Investigation of Past Human Relationships With Now‐Endangered Fish Species: Lake Sturgeon and American Eel in Southern Ontario, Canada

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper explores the historical ecology and biogeography of two fish species that are currently endangered in the North American Great Lakes region, that were of great importance to the Indigenous people in the region, and that are the focus of ongoing conservation efforts on the part of descendant communities: lake sturgeon (Acipenser ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Visual and genetic stock identification of a test fishery to forecast Columbia River spring Chinook salmon stocks 2 weeks into the future

Evolutionary Applications
Modern fisheries management strives to balance opposing goals of protection for weak stocks and opportunity for harvesting healthy stocks. Test fisheries can aid management of anadromous fishes if they can forecast the strength and timing of an annual ...

Centring care as part of Indigenous environmental stewardship: Collective learning through cultural plants

People and Nature, EarlyView.
Abstract Stewardship is broadly defined as ‘universal responsibility of humanity to care for the planet, to ensure that it can continue to provide the essential natural resources for life’. Stewardship practices shape ecosystems, create diverse biocultural landscapes, and can enhance the productivity, availability and health of plants used by ...

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the
