Hypnea Ceramioides
''Hypnea'' is a genus of red algae, and a well known carrageenophyte (plant producing polysaccharide carrageenan). Taxonomy and Nomenclature ''Hypnea'' is a genus of red seaweed under class Florideophyceae, order Gigartinales, and family Cystocloniaceae. There are 99 species listed on Algaebase with 78 being accepted taxonomically. The genus was originally classified under family Hypneaceae, which was considered distinct from Cystoclonoiaceae on the basis of differences in their carposporophyte structure, and the shape of the thalli and cortical cells. Differences in carrageenan chemistry, with Hypneaceae species producing kappa-carrageenan and Cystocloniaceae producing lambda-carrageenan, was another reason for their distinction. However, these criteria were questioned and molecular analysis later showed that the two families had similar vegetative and reproductive characters. Furthermore, it was proven that lambda-carrageenan and kappa-carrageen coexist within the Gigartina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biological Dispersal
Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal'), as well as the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. The act of dispersal involves three phases: departure, transfer, settlement and there are different fitness costs and benefits associated with each of these phases. Through simply moving from one habitat patch to another, the dispersal of an individual has consequences not only for individual fitness, but also for population dynamics, population genetics, and species distribution. Understanding dispersal and the consequences both for evolutionary strategies at a species level, and for processes at an ecosystem level, requires understanding on th ...
