The present paper is a first addition to the preliminary catalogue of the heteroptera-fauna of the Canary Islands (HEISS & BÁEZ, 1990) and includes corrections, new taxonomic assignments and further citations from literature ...

After 140 years of study, the Azorean beetle fauna is, in some islands, still poorly known, with 51 families, 305 genera, and species present in the whole archipelago (61 of which - 11,6% - seem to be endemic). The intention ...

Invertebrate communities in volcanic habitats of different ages on the islands of La Palma and El Hierro were studied using standardized trapping and searching techniques. A variety of graphical and numerical approaches ...

Algal zonation patterns were studied in two sites (Caloura, South coast and Ribeirinha, North coast) of the island of Sao Miguel, Azores. At each site two stations were studied and the transects revealed the occurrence of ...

Oxychilus (Drouetia) is an endemic terrestrial mollusc from the Azores that shows a high degree of both anatomical and morphological variability. In order to support a biochemical systematic study, several potential taxonomic ...

The small helicid snail Heterostoma paupercula occurs in the Azores and Madeira. Previously regarded as a single species, it was split into genera on the basis of variation in shell morphology and genital anatomy: Heterostoma ...

St. Helena (South Atlantic Ocean) and Macaronesia have endemic plants that have been interpreted as relicts. This paper divides these relicts into three main types. It is suggested that type one relicts are of Miocene age. ...

Habitat use and microclimatic constraints on the activity of the endemic Madeiran speckled wood butterfly and European speckled wood were studied in September 1989 and April 1990. The endemic species is the most closely ...

Until recently the North Atlantic Islands were believe to house only mammals introduced by humans. Recent work has demonstrated that at least the Canary Islands house(d) a native mammal fauna. New data including chromosome ...

The morphological and genetic differences between populations of Canarian lizards on four islands were analysed in relation to two ecological systems: the laurisilva forest and the young volcanic ecosystems or 'malpaises'. ...
