The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Examining the maternal investment of the calyptra and its influence on the sporophyte offspring [PDF]

, 2021
Maternal care is a critical component of offspring survival, development, and fitness in many organisms. In early diverging lineages of plants (mosses, liverworts, and hornworts), offspring sporophytes are physically attached to and nutritionally ...

Finding the sweet spot: An exploration of environmental factors to optimize Ulva carbohydrate content and composition

Journal of Phycology, EarlyView.
Abstract Green macroalgae from the Ulva genus are rich in polysaccharides of interest, including ulvan, starch, and cellulose. However, their content and structure are impacted by environmental factors, which poses challenges for industrial applications, especially in the context of climate change.

Origin and Persistence of Lycopodium clavatum and Lycopodium annotinum (Lycopodiaceae) in Scots Pine Forests

Plants
Understanding the growth dynamics of spore-bearing clonal plant sporophytes and the influence of abiotic and biotic factors is crucial for predicting the persistence of club moss populations and implementing effective habitat management techniques ...

The Habitat of the Neglected Independent Protonemal Stage of Buxbaumia viridis

Plants, 2021
Buxbaumia viridis is a well-known species of decaying deadwood, which is protected in Europe. All previous studies dealing with the ecology of B. viridis rely on the sporophyte generation because the gametophyte generation is allegedly undetectable ...

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.

In Vitro Development of Gametophyte and Sporophyte in Several Fern Species

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2008
The in vitro differentiation of the gametophyte and sporophyte of Pteridophyta, conducted through the culture, on nutritive media, of the green, incompletely differentiated sporangia and spores, exhibits a variety of peculiarities. Whereas in the case of

Microscopic Stages of North Atlantic Laminaria digitata (Phaeophyceae) Exhibit Trait-Dependent Thermal Adaptation Along Latitudes

Frontiers in Marine Science, 2022
Kelp forests in the North Atlantic are at risk of decline at their warm temperature distribution margins due to anthropogenic temperature rise and more frequent marine heat waves. To investigate the thermal adaptation of the cold-temperate kelp Laminaria
