DISTRIBUCIÓN Y DATOS BIOLÓGICOS DE LOS CANGREJOS ERMITAÑOS (DECAPODA: ANOMURA) DEL MAR CARIBE COLOMBIANO COLECTADOS POR LA EXPEDICIÓN INVEMAR-MACROFAUNA II

During the expedition INVEMAR-Macrofauna II, made in 2001 throughout the continental shelf and upper continental slope of the Colombian Caribbean coast, between 20 and 500 m depth, 22 species of hermit crabs distributed in one superfamily and four families, were collected. Within the superfamily Paguroidea, the family Paguridae was the most abundant and diverse with 13 species, six species belong to family Diogenidae; the Parapaguridae was represented by two species and one species of the genus Trizocheles of the family Pylochelidae represents the !rst report of this family from this coast. In addition, !ve undetermined species of the genera Paguristes, Enneobranchus, and Iridopagurus, were also collected. Based on the collected material, the bathymetric distributions reveal species aggregation in two depth ranges (20 - 150 m and 300 - 500 m). The upper strata species show a geographic distribution pattern, seemingly related to the in"uence of the Magdalena river; by contrast, the species from the deeper range do not reveal any particular distribution pattern.

Bromeliaceae species from coastal restinga habitats, Brazilian states of Rio de Janeiro, Espírito Santo, and Bahia

Bromeliaceae is one of the most representative plant families in restinga habitats. We analyzed the species richness and composition of Bromeliaceae in 13 restinga habitats along the Brazilian coast. We found a total of 41 species distributed along the restinga habitats studied. The restinga of Praia do Sul, in the state of Rio de Janeiro, had the highest number of species (15), whereas the restinga of Abaeté, in the state of Bahia, had the lowest (4). Our data are suggestive that the Doce River may represent the limit of distribution for some bromeliad species, with some species occurring only south of that river and others occurring only to the north of it. The differences in Bromeliaceae species composition among restinga habitats probably are not only due to differences in local environmental conditions, but also due to the geographic distribution pattern of each species and to the present degree of disturbance at each restinga.

Numerical analyses of wild Jurinea spp. (Asteraceae) in Turkey

Eighteen taxa of the genus Jurinea Cass. growing naturally in Turkey were classified by numerical taxonomic analysis. Morphological and palynological characters of each individual were measured and quantified on the basis of 51 traits. Ten plants were chosen randomly for the measurements of metric characters related to the external morphology of the taxa and the average values used for statistical analysis via NTSYS-pc package. Standardized data were used to generate the dendrogram that revealed the phenetic relationships of the taxa. Geographic distribution pattern of the Jurinea species appear to be closely related to the Anatolian Diagonal.
