Sexual reproduction in octocorals
For octocorals, sexual reproductive processes are fundamental to maintaining populations and influencing macroevolutionary processes. While ecological data on octocorals have lagged behind their scleractinian counterparts, the proliferation of reproductive studies in recent years now enables comparisons between these important anthozoan taxa. Here we review the systematic and biogeographic patt...
متن کاملReproduction in Octocorals (Subclass Octocorallia): A Review of Published Literature
The Subclass Octocorallia represents a geographically and morphologically diverse group of Cnidarians for which basic life history, including reproductive biology, is poorly known in most species. Current knowledge of reproduction in this group is derived from a few of taxonomic descriptions which include information on reproductive morphology (e.g. Kukenthal 1919), and a limited number of publ...
متن کاملSexual reproduction in Aspergillus flavus.
Aspergillus flavus is the major producer of carcinogenic aflatoxins in crops worldwide and is also an important opportunistic human pathogen in aspergillosis. The sexual state of this heterothallic fungus is described from crosses between strains of the opposite mating type. Sexual reproduction occurred between sexually compatible strains belonging to different vegetative compatibility groups. ...
متن کاملEffects of Sexual Reproduction
Example 5.5: Near-critical binary splitting. The theorem applies to binary splitting where the probability of division is p(z) = 1/2+1/(2z), and q(z) = 1− p(z) is the probability of no children, if population size is z. Thus, m(z) = 1 + 1/z and the process is supercritical, but approaches criticality as z increases. The probability generating function of the offspring number is fz(s) = q(z) + p...
متن کاملEvolution of fungal sexual reproduction.
We review here recent advances in our understanding of the genetic, molecular and genomic basis of sex determination and sexual reproduction in the fungal kingdom as a window on the evolution of sex in eukaryotes more generally. In particular, we focus on the evolution of the mating-type locus and transitions in modes of sexual reproduction using examples from throughout the kingdom. These exam...
