Evolution of Sexual Reproduction in Marine Invertebrates: by Andrew (Andrey N.) Ostrovsky

By Andrew (Andrey N.) Ostrovsky

3 significant features that distinguish this booklet are that (1) it comprises the main distinctive research of the sexual copy (oogenesis, fertilization and embryonic incubation) in a specific phylum of the aquatic invertebrates (Bryozoa) ever made; this research is predicated on an exhaustive evaluate of the literature on that subject released during the last 260 years, in addition to huge unique histological, anatomical and morphological information acquired in the course of stories of either extant and extinct species; (2) this wide research has made it attainable to reconstruct the main styles, levels and traits within the evolution of sexual copy in a number of bryozoan clades, displaying quite a few examples of parallelisms in the course of transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic improvement are mentioned intimately; and (3) the foremost evolutionary novelties bought through Bryozoa are in comparison with related ideas that experience advanced in different teams of marine invertebrates, displaying the overall developments within the evolution in their sexual copy. Ecological history of those ideas is taken into account too. Altogether those elements make the monograph an “Encyclopedia of bryozoan sexual reproduction,” delivering an fundamental photo of the evolution of this complicated phenomenon.
