P110-00 Shape distances, shape spaces, and the comparison of morphometric methods Monteiro LR, Bordin B, Reis SF* The major development reported by F. J. Rohlf and L. F. Marcus was the establishment of a geometric framework for the description of shape as envisioned by D. Thompson and formalized in the path-breaking work of Kendall, Bookstein and Goodall. In this essay the new developments of morphometrics are reviewed with an emphasis on the simulation approaches developed to compare morphometric methods by visualizing the spaces implied by each technique in each of the different approaches.

P111-00 Variation in mandible shape in Thrichomys apereoides (Mammalia: Rodentia): Geometric analysis of a complex morphological structure Duarte LC, Monteiro LR, Von Zuben FJ, Reis, SF* The model of development and evolution of complex morphological structures conceived by Atchley and Hall in 1991 (Biol. Rev. 66:101-157), which establishes that changes at the macroscopic, morphogenetic level can be statistically detected as variation in skeletal units at distinct scales, was applied in combination with the formalism of geometric morphometrics to study variation in mandible shape among populations of the rodent species Thrichomys apereoides. Morphogenetic mechanisms are assumed to be operating to produce the observed differentiation in the specific units of the mandible include mesenchymal condensation differentiation, muscle hypertrophy, and tooth growth. Perspectives for the application of models of morphological evolution and geometric morphometrics to morphologically based systematic biology are considered. Systematic Biology 49: 563-578, 2000.

P112-00 Populations Dynamics and Secondary Production of Laeonereis aculta (Treadwell, 1923) (Nereididae: Polychaeta) Omena EP, Amaral ACZ* Population dynamics and productions of Laeonereis aculta (treadwell, 1923) were investigated on a tidal flat on the southeast coast of Brazil (Enseada Beach, São Sebastião, state of São Paulo) between August 1995 and March 1997. Higher densities (3.5 ind.0,01 m-2) were found during summer months, mainly during March 1996 and February-March 1997. Growth was analized using computer based methods of lengh-frequency data (Elefan), which estimate growth parameters of the Von Bertalanffy formula (VBGF). Two cohort could be distinguished, one in December 1995 (with an equivalent cohort in December 1996) and another one in April 1996. The life cycle of L. Acuta may be strongly influenced by photoperiod, temperature regime and availability of food. The results of the present work were discussed in comparison with another sand flat polychaete species in the same area and other nereidid species. Bulletin of Marine Science 67(1): 421-431, 2000.

P113-00 Two species of Marphysa Quatrefages, 1865 (Eunicidae, Polychaeta) from intertidal sandy beaches of the São Sebastião Channel, State of São Paulo (Brazil) Steiner TM, Amaral ACZ* This paper reports the presence of two new species of Marphysa from São Sebastião Channel, State São Paulo, Brazil, M. Sebastiana n. sp. And M. Formosa n. sp. both collected from intertidal sandy beaches. These species belong to the group of Marphysa that has branchiae scattered over an extensive region of the body and parapodia with both compound falcigerous and spinigerous chaetae. Comparisons between the two new species and M. digitibranchia Hoagland, 1920, M. orensanzi Carrera-Parra and Salazar-Vallejo, 1998, Marphysa sp. B (Gardiner, 1975), and Marphysa sp. (Winsnes, 1989) are presented. Bulletin of Marine Science 67(1): 479-489, 2000. IF = 0.502 *E-mail:
P114-00 Amphicorina schlenzae, a small sabellid (Polychaeta, Sabellidae) associated with a stony coral on the coast of São Paulo State, Brazil Nogueira JMM, Amaral ACZ* Colonies of the stony coral Mussismilia hispida were collected form island off shore of São Paulo State, de-calcified, and the polychaetes sorted and identified. Spionids, syllids, and sabellids were the most common families, and among the sabellids, a new species of Amphicorina was found. Amphicorina schlenzae is described and comparisons with the closest species are given. Bulletin of Marine Science 67(1): 617-623, 2000. IF = 0.502 *E-mail:
P115-00 Clustering behavior of the hermit crab Clibanarius antillensis (Decapoda, Anomura) in a rocky shore at São Sebastião, southeastern Brazil Turra A, Leite FPP* This study was undertaken in Praia Grande, São Sebastião, southeastern Brazil. Sampling was done with the use of transects and 1m2 quadrates. Clibanarius antillensis was the most abundant hermit crab species and occurred mainly in air exposed sites. Clustered and scattered individuals presented similar patterns of shell utilization. The number and size of clusters were larger in exposed areas than in submerged ones. All females were clustered and 44,44% were ovigerous. Clustered males and females and scattered males presented similar sizes. The pattern of clustering seems to be strongly influenced by the spatial heterogeneity and by the ability of the crabs to deal with the risks of desiccation and thermal stress.

P116-00 Avaliação e ações prioritárias para a conservação da Biodiversidade da zona costeira e marinha. Diagnóstico sobre Praias Arenosas Amaral ACZ, Amaral EHM, Leite FPP*, Gianuca NM O trabalho realizado revelou que existem inúmeros sistemas de praias e dunas costeiras para os quais não se dispõe de qualquer inventario faunístico, o que torna absolutamente impossível realizar estudos e analises comparativas sobre a biodiversidade desses sistemas em diferentes pontos do litoral brasileiro. Por conseqüência, torna-se inviável qualquer tentativa de demarcação de áreas nessas regiões de interesse para a preservação da biodiversidade. Não obstante, a partir dos estudos conhecidos para as regiões sul e sudeste, para alguns pontos do litoral nordeste e norte e, principalmente, com base em informações pessoais obtidas, foi possível identificar e propor vários trechos de praias e dunas considerados de alto interesse para a preservação da integridade e biodiversidade dos ecossistemas litorâneos brasileiros.

P117-00 Structure and proteoglycan composition of specialized regions of the elastic tendon of the chicken wing Carvalho HF*, Felisbino SL, Covizi DZ, Della Colleta HHM, Gomes L The elastic tendon of the avian wing has been described by others as a unique structure with elastic properties due to the predominance of elastic fibers in the midsubstance. Analyses of the tendon have shown it to possess in addition to the major elastic region, a distally located fibrocartilage and three tendinous regions, anatomically and biochemically distinct. These results demonstrate that the elastic tendon is a complex structure with complex regional structural and compositional adaptations, suited to different biomechanical roles.

P118-00 The osteochondral ligament: a fibrous attachment between bone and articular cartilage in Rana catesbeiana Felisbino SL, Carvalho HF* The anuran epiphyseal cartilage shows lateral expansion that covers the external surface of the bone, besides other features that distinguish it from the corresponding avian and mammalian structures. The fibrous structure that attachs the lateral cartilage to the bone (osteochondral ligament, OCL) was characterized ultrastructurally and by immunocytochemistry in Rana catesbeiana. The results presented in this paper showed that the osteochondral ligament of Rana catesbeiana is a complex and specialized fibrous attachment which guarantees a strong and flexible anchorage of the lateral articular cartilage to the periosteal bone shaft, besides playing a role in bone growth.

P119-00 Collagen Fiber Reorganization in the Rat Ventral Prostate Following Androgen Deprivation: A Possible Role for the Smooth Muscle Cells Vilamaior PSL, Felisbino SL, Taboga SR, Carvalho HF* We characterized the reorganization of the collagen fibers in the ventral prostate of castrated rats, using histochemical tests and immunohistochemistry for type I and III collagens plus confocal microscopy of triple labeled (collagen III, actin and DNA) tissue sections. We have shown that collagen fibers are composed of type I and type III collagens and that they are progressively concentrated around the epithelial structures (ducts and acini) and become increasingly undulated and folded. Double labeling of collagen fibers and F-actin has demonstrated that the smooth muscle cells are closely associated with the collagen fibers. The results demonstrated a marked reorganization of the collagen fibers and suggest an active role of the SMC in the reorganization of the fibrillar components of the stroma.
