BACKGROUND The Atlantic Forest is globally one of the priority ecoregions for biodiversity conservation. In Argentina, it is represented by the Paranense Forest, which covers a vast area of Misiones Province between the Paraná and Uruguay rivers. The Uruguay River is a global hotspot of freshwater gastropod diversity, here mainly represented by Tateidae (genus Potamolithus) and to a lesser exte...

The genus Sibogasyrinx has to date included only four species of rare deep-water Conoidea, each known from few specimens. In shell characters it strongly resembles three distantly-related genera, two which, Comitas and Leucosyrinx, belong a different family, the Pseudomelatomidae. A molecular phylogenetic analysis large amount material Conoidea revealed existence much additional undescribed div...

Trapania is the second largest genus belonging to family Goniodorididae, of which most species are reported from Indo-Pacific waters. To date, there nine distributed along temperate coasts East Atlantic Ocean and Mediterranean Sea: fusca, graeffei, hispalensis, lineata, maculata, orteai, pallida, sanctipetrensis tartanella. However, validity some these has been problematic due uncertain taxonom...

In recent years there have been a number of analyses of patterned activity in invertebrate ganglia. Examples include the studies of crayfish swimmeret beat (Hughes & Wiersma, i960), the flight system of insects (Weis-Fogh, 1964; Wilson, 1966; Wyman, 1966) and crustacean heart-beat control (Maynard, 1966). In the Mollusca, Horridge (i960) described the production of patterned discharges from the...

Public participation geographic information systems (PPGIS) increasingly are utilized in geographic research, yet researchers rarely are provided with guidance on how to implement PPGIS in an appropriate and effective manner. This article reports on the process of research that explores responses to current and future local tourism development offered by a sample of residents using a modified P...
