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.作者: headlong 時間: 2025-3-22 00:59

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.作者: 引起 時間: 2025-3-22 11:23
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.作者: 詳細目錄 時間: 2025-3-22 16:09
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.作者: 羊齒 時間: 2025-3-22 20:22 作者: debris 時間: 2025-3-22 23:16 作者: 外向者 時間: 2025-3-23 02:32
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作者: 圓柱 時間: 2025-3-23 07:00

General characteristics of the gamete ultrastructures of the two forms are very similar, though some minor differences were detected between them.

Nereidid polychaetes as model organisms for marine chemical ecology,eromones attract the sexual partner and ensure the coordinated release of gametes by both sexual partners.

Development of Perviata and Vestimentifera (Pogonophora),en reported from both groups, but further clarification is desirable.
