Genomic analyses of giant kelp reveal restricted connectivity across the Southern Hemisphere and striking diversity in Aotearoa (New Zealand)

Journal of Phycology, EarlyView.
Abstract The macroalga Macrocystis pyrifera (“giant” or “bladder” kelp) plays a vital role in cold‐temperate marine ecosystems but faces increasing threats from ongoing environmental change. Understanding its population diversity and connectivity is essential for predicting future range shifts and assessing the ecological consequences of such shifts in

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.

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

Genome‐wide association study of morphometric and metabolic characteristics in European populations of the sugar kelp Saccharina latissima

Journal of Phycology, EarlyView.
Abstract The sugar kelp Saccharina latissima is a promising candidate for sustainable aquaculture in the North Atlantic and Northeast Pacific, but genetic improvement has been hindered by a limited understanding of the genetic basis of economically important traits.

Permissible presupposition

Mind &Language, EarlyView.
When is it proper or acceptable for a speaker to presuppose a proposition in the course of performing a speech act? Taking Stalnaker's common ground model as my background, I argue that this is best framed as a matter of the conversational permissibility of the speaker's presupposition, and that we should not construe this permissibility in terms of ...

Virtuous Deferral

Noûs, EarlyView.
ABSTRACT Virtue epistemology has long struggled with the “Creditability Dilemma”: how can knowledge gained through deference be creditable to the knower if it primarily depends on others’ cognitive work? We propose a novel solution by developing a telic account of doxastic deference as a distinctive kind of social‐epistemic performance.

Secrecy: An Epistemological Account

Noûs, EarlyView.
ABSTRACT Although the ethical and political implications of secrecy are significant, I argue here that its fundamental nature is epistemological and that any account of its nature must be based on its epistemological profile. In particular, I propose examining secrecy within the framework of social and political epistemology, considering secrets as ...

Indigenous resurgence in the Blue Economy: Relational values to guide kelp mariculture

People and Nature
Decisions about how to use ocean spaces are increasingly attuned to issues of social equity, environmental sustainability and climate resilience, yet often bypass local governance, knowledge, values and thus objectives.

Resilience and stability of kelp forests: The importance of patch dynamics and environment-engineer feedbacks.

PLoS ONE, 2019
Habitat forming 'ecosystem engineers' such as kelp species create complex habitats that support biodiverse and productive communities. Studies of the resilience and stability of ecosystem engineers have typically focussed on the role of external factors ...
