Nonhuman Pedagogical Relations: Towards Conceptual Limits

Educational Theory, EarlyView.
Abstract This article considers the pedagogical relation as a relation to a nonhuman educator, wherein the educatee is a member of the Homo sapiens species. My aim is to clarify the extent to which a nonhuman‐human relation can be understood as pedagogical.

Dispersal synchronizes giant kelp forests

Ecology
AbstractSpatial synchrony is the tendency for population fluctuations to be correlated among different locations. This phenomenon is a ubiquitous feature of population dynamics and is important for ecosystem stability, but several aspects of synchrony remain unresolved.

Approaches to managing kelp forests [PDF]

, 2023
Highlights : > Managing the harvesting of wild growing kelp is still the most developed form of kelp management. > Humans’ intensifying use of the ocean is exposing kelp to many pressures in addition to harvesting. The cumulative impacts of these pressures need to be addressed in an integrated manner.

Using Catch Data to Estimate Changes in Global Commercial Abalone Abundance

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in global wild capture production of abalone are explored to infer potential changes in biological stocks. The study found that 77% (or 10 out of the 13) of the countries that reportedly caught abalone in the wild have experienced declines in catches between 1980 and 2023, and on aggregate catch declined by almost 83% between 1980 and ...

Back to the past: long-term persistence of bull kelp forests in the Strait of Georgia, Salish Sea, Canada

Frontiers in Marine Science
The Salish Sea, a dynamic system of straits, fjords, and channels in southwestern British Columbia, is home to ecologically and culturally important bull kelp (Nereocystis luetkeana) forests. Yet the long-term fluctuations in the area and the persistence

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Changing nutritional seascapes of kelp forests

Frontiers in Marine Science, 2023
Ocean warming and short-term extreme events (e.g. marine heatwaves) are becoming more intense and frequent and have had major impacts on ecosystems. Seaweeds are foundational components of temperate reefs, providing nutrition for a diversity of species and underpinning temperate food webs.

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change

Journal of Phycology, EarlyView.
Abstract Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long‐term success of kelp restoration.

Biodiversity of Kelp Forests and Coralline Algae Habitats in Southwestern Greenland

Diversity, 2018
All marine communities in Greenland are experiencing rapid environmental change, and to understand the effects on those structured by seaweeds, baseline records are vital.

Macroalgae respond to consumer‐mediated nutrient cycling in a temperate ecosystem

Journal of Phycology, EarlyView.
Abstract Primary production in coastal upwelling regions has often been presumed to be supported primarily by allochthonous nutrients, but inconsistent nutrient delivery and the metabolic cost of nitrate assimilation can leave producers nitrogen limited during the growing season. As a potential supplement for insufficient allochthonous supply, nutrient
