The species of Hippolyte Leach (Crustacea, Caridea, Hippolytidae) from Terminos Lagoon, southwestern Gulf of Mexico

The taxonomic identity of specimens of the genus Hippolyte Leach, 1814 of Laguna de Términos was considered including the colour and the presence-absence of tufts of plumose setae on the dorsal surface of the carapace and abdomen as secondary characteristics to morphological features of taxonomic value. Two groups were formed based on appearance: one transparent with setae and another green without setae. The analysis of five morphological characteristics in adult females of the two groups made it possible to identify only H. zostericola (Smith, 1873). Fecundity and fertility were similar (0.5>p>0.2) in both groups. The first zoea of both groups were also morphologically similar. Considering these results, it is concluded that the only species collected was H. zoslericola and that it has two phenotypical types. It is recomended that the morphological analysis of all larval stages be carried out.

SEABATHER'S ERUPTION: A CLINICAL and EPIDEMIOLOGICAL STUDY of 38 CASES IN SANTA CATARINA STATE, BRAZIL

Seabather's eruption (SBE) is an intensely itchy, papule-erythematous dermatitis that occurs predominantly in regions of the body covered by bathing costumes, after exposure to marine water. The planulae larvae of Linuche unguiculata scyphomedusae (thimble jellyfish) are the etiologic agent of the dermatitis, which is frequent in waters of Caribbean, Gulf of Mexico and Florida. The authors report 38 cases of SBE in the State of Santa Catarina (Southern region of Brazil), with emphasis on their clinical and epidemiological aspects, such as profile of victim, topography of the papules and conditions predisposing to the accident.

Genetic parameters of racing performance traits of Quarter horses in Brazil

The data used in the present study were recorded at the Jockey Club of Sorocaba for 5094 racing performance of 1350 Quarter Horses at the Paulista Race Track of Sorocaba, state of São Paulo, Brazil, from 1991 to 1997. The considered traits were time and final rank. The model used in analysis included random animal and permanent environmental effects, and race, sex, age and origin as fixed effects. The variance and covariance components were estimated by the restricted maximum likelihood for an animal model, using the derivative-free process method and the MTDFREML software. For the time, heritability was 0.17 (0.05), while estimate of repeatability 0.55 (0.05). The lower heritability for the final rank, 0.13 (0.04), indicate that this trait is not the most appropriate one for inclusion in programs of Quarter horse selection in Sorocaba racetrack. The repeatability estimate for rank was 0.44 (0.04) and the genetic correlation between this trait and time was 0.99.
