Population level variation in reproductive development and output in the golden kelp Laminaria ochroleuca under marine heat wave scenarios

Frontiers in Marine Science, 2022
Thermal tolerance is often interpreted as a species-wide thermal niche in the absence of studies focusing on the adaptive potential of populations to exhibit differential thermal tolerance.

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.

Variability in per capita oogonia and sporophyte production from giant kelp gametophytes (Macrocystis pyrifera, Phaeophyceae) Variabilidad de la producción per cápita de oogonios y esporofitos de huiro (Macrocystis pyrifera, Phaeophyceae)

Revista Chilena de Historia Natural, 2004
Vegetative growth and fertility of kelp gametophytes are thought to be antagonistic, such that most successful kelp recruitment is assumed to result from fertilization of single oogonia released from unicellular female gametophytes.

Green gravel as a vector of dispersal for kelp restoration

Frontiers in Marine Science, 2022
Kelp forests are experiencing substantial declines due to climate change, particularly ocean warming and marine heatwaves, and active interventions are necessary to halt this decline.

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.

Methods for characterizing pollen fitness in Cannabis sativa L.

PLoS ONE, 2022
Pollen grains are male gametophytes, an ephemeral haploid generation of plants, that commonly engage in competition for a limited supply of ovules. Since variation in reproductive capabilities among male gametophytes may influence the direction and pace ...
