Post-doctoral
Project
Systematic revision and
phylogeny of the genus Chrysaora Peron & Lesueur, 1810 (Cnidaria:
Scyphozoa: “Semaeostomeae”: Pelagiidae).
The work started in November 2003 finishing in May 2006 with FAPESP
support and scholarship (03/02432-3 and 03/02433-0)
The
genus Chrysaora is the most numerous (species) within the subclass
Discomedusae. But, there are species with problems in their definitions. Some
species had few reports in the literature, besides their original descriptions.
Species of the genus may have economical impacts (affecting fisheries, tourism,
and causing accidents). The phylogeny already proposed for the family, is not
accompanied by a revision of the group, do not include all valid or nominal
species, and include species not yet described. The project goal is to revise
all valid species of the genus Chrysaora and propose a new phylogeny for
the group using morphological and life cycle characters.
PhD Thesis
Population structure of Chrysaora
lactea and Lychnorhiza lucerna (Cnidaria, Scyphozoa) in plankton
samples, with the redescription of the species.
scholarship FAPESP (n. 99/05374-7), defended on October
2003
The population structures of the medusoid scyphozoan species Lychnorhiza
lucerna Haeckel, 1880 and Chrysaora lactea Eschscholtz, 1829 were
studied in the Cananeia region, southern coast of Sao Paulo state. The species
were sampled through plankton nets, at surface water, and stranded on the beach
at the southernmost area of Ilha Comprida. During the two years and nine months
of collecting, no ephyra was found in plankton samples. Seasonal occurrence was
observed for both species, with recruitment on spring. Large interannual
variation occurrence was also observed. The gametogenesis of the species is
described. The life cycle of Chrysaora lactea is metagenetic and was
completed with laboratory rearing observations. The life cycle of Lychnorhiza
lucerna remains unknown. Both species were redescribed based on the
collected specimens, focusing on the description of juveniles.

Gametogenesis and embryonic

Nausithoe aurea Silveira & Morandini, 1997 is a metagenetic and
dioecious species with external fertilization. The oocytes are released
continuously (55 days in laboratory), but with great variation in the daily
number. In the embryonic development the cleavage, after the 8 cells stage,
changes from holoblastic and adequal to pseudospiral. The gastrulation occurs
through multipolar ingression and begin 24 hours after fertilization. The
general histological structure of the gonads resembles other Scyphozoa, in
which the gonocytes proliferate from the gastrodermis, migrate and
differentiate in the mesoglea. In the male gonad the germ cells are arranged in
distinctive layers and form follicles (cysts). In the female gonad the oocytes
develop from the germinative zone in the gastrodermis and present a maturing
gradient from this point on (oral-aboral sections). The oocytes are free in the
gonad mesoglea, without association to any cell. The spatial relation of the
coronal musculature, gonads and coronal groove, is a character to be used in the
systematics of the genus Nausithoe Kolliker, 1853.
