Gonad characterization and reproductive cycle of Collisella subrugosa (Orbigny, 1846) (Gastropoda: Acmaeidae) in the northeastern Brazil.
Gonad characteristics and reproductive cycle in the acmaeid Collisella subrugosa from Northeastern Brazil were investigated. The individuals were collected monthly from February 1993 to April 1994 at Farol do Mucuripe Beach, Fortaleza, Ceará, Brazil. There is no external characteristic on the shell and the soft body structures except the gonad that allows sex differentiation. The gonad of limpe...
متن کاملMolecular phylogeny and biogeography of the endemic Hawaiian Succineidae (Gastropoda: Pulmonata).
The endemic Hawaiian Succineidae represent an important component of the exceptionally diverse land snail fauna of the Hawaiian Islands, yet they remain largely unstudied. We employed 663-bp fragments of the cytochrome oxidase I (COI) mitochondrial gene to investigate the evolution and biogeography of 13 Hawaiian succineid land snail species, six succineid species from other Pacific islands and...
متن کاملPhylogenetic analysis of Biomphalaria tenagophila (Orbigny, 1835) (Mollusca: Gastropoda).
Mitochondrial DNA of Biomphalaria tenagophila, a mollusc intermediate host of Schistosoma mansoni in Brazil, was sequenced and characterised. The genome size found for B. tenagophila was 13,722 bp and contained 13 messenger RNAs, 22 transfer RNAs (tRNA) and two ribosomal RNAs (rRNA). In addition to sequencing, the mitochondrial DNA (mtDNA) genome organization of B. tenagophila was analysed base...
متن کاملReproduction of Omalonyx matheroni (Gastropoda: Succineidae) under laboratory conditions.
The life histories of succineids have received relatively little attention. To evaluate life history characteristics of Omalonyx matheroni, we studied a Brazilian population (Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala, in Caratinga, Minas Gerais, Brazil) under laboratory conditions. The aims of the present study were (1) to describe in detail an appropriate rearing method;...
متن کاملLand slugs (Gastropoda: Pulmonata) on birds demonstrate dispersal potential
We describe the discovery of two slugs, Arion subfuscus and Deroceras reticulatum, on living adult birds captured for banding at Powdermill Nature Reserve, Rector, Pennsylvania. The presence of slugs on birds suggests that bird transport might play a role in slug dispersal. Additional keywords: Gray fieldslug, Deroceras reticulatum, dusky arion slug, Arion subfuscus, common yellowthroat, Geothl...
