Sexual conflict and mating systems in the dorvilleid genus , and the dinophilid genus ,,e males as mates. In the gonochoric species of . different population structures (either panmictic or with sib-mating) select either for absence of sexual dimorphism and a 1:1 sex ratio or for strong sexual dimorphism and female biased sex ratio.

adaptive radiation which has made it possible for theseanimals to colonize almost all marine, limnic and terrestrialbiotopes. In doing so they have evolved a great variety of life forms,and their reproduction and development are correspondingly diverse,with many modes and patterns unique in the anim

Lymphocyte

Development of Perviata and Vestimentifera (Pogonophora),higher taxon. An annelidan relationship is indicated because the ciliated settlement stages of both are like annelid trochophores in their ciliation and in the way they develop chaetae initially on two segments.

引起

The ancestral cleavage pattern of the clitellates and its phylogenetic deviations,e yolk which are nourished by the surrounding fluid within the cocoon. Comparisons with polychaetes lead to the conclusion that an early specification of the 2d cell must be a feature of the annelid ancestor and that equal cleavage represents the derived case in the annelids.

Cellular origins of bilateral symmetry in glossiphoniid leech embryos,adult. This requires that the first cleavage be skewed with respect to the A–P axis. Here, we re-examine the fates and behaviours of early blastomeres and conclude that a more accurate representation of the embryo is to have the first cleavage plane transverse to the A–P axis.

Reproduction of the Syllidae (Annelida: Polychaeta),d by epitoky (as epigamy and stolonization, respectively), swarming and external fertilization. Deviations from the primitive type, particularly evident in meiofaunal species, include external brooding, direct sperm transfer, internal fertilization, viviparity, parthenogenesis, and simultaneous as w

Reproduction and larval development of the spioniform Polychaeta with application to systematics an species belonging to the genus . and some polydorids. Both architomy and paratomy are known, with the latter limited to small species of . (sometimes referred to .) and one species of .. Architomy is often the primary form of reproduction in . and contributes to the maintenance of large populations
