Ecological relations between mangrove leaf litter and the spatial distribution of the gastropod Melampus coffeus in a fringe mangrove forest Iheringia, Sér. Zool.
Tavares,Diva S.; Maia,Rafaela C.; Rocha-Barreira,Cristina; Matthews-Cascon,Helena.
Leaf litter represents a food source to many organisms that may directly contribute to organic matter decomposition. In addition, the physical presence of these vegetal detritus contributes for the modification of some environmental areas and produce microhabitats that may act as a refuge against predators and desiccation for many animals. The pulmonate gastropod Melampus coffeus (Linnaeus, 1758) (Ellobiidae) is a very common specie in Atlantic Coast mangrove forests and feeds on fallen mangrove leaves. It was hypothesized that the spatial distribution of Melampus coffeus is directly affected by mangrove leaf litter biomass deposition. Thus, this research aimed at evaluating the spatial distribution of these gastropods in relation to the biomass of...

Die Evolution der Archaeopulmonata Naturalis
Harbeck, K..
The Archaeopulmonata are revised, using characters of the shell and the radula, while data concerning the ontogeny and ecological data are also taken into account. Archaeopulmonates are a group of the pulmonates with some conspicuous plesiomorphous character states They differ from the basommatophores and the stylommatophores by the presence of veliger larvae. This is seen in the early ontogenetic development of all members of the families of Archaeopulmonata, which are: Carychiidae, Chilinidae (incl. Latiinae), Siphonariidae, Onchidiidae, Amphibolidae, Otinidae and Ellobiidae (with most numerous genera and species). Altogether 33 genera and 59 recent species are discussed. Fossil material shows that the roots of this stem-group are old. Jurassic and...
