Cervera atlantica, a small stoloniferan octocoral, was described as Cornularia atlantica by James Yate Johnson in 1861 from Funchal, Madeira. It then remained unrecognized until 1972 when I discovered it on the Mediterranean coast of Spain. I have since confirmed its existence at the type locality and have traced its distribution around Madeira, throughout the Canary Islands, and on Portuguese and English coasts. In the Mediterranean Sea, I have found it along Spanish and French coasts, among the Balearic Islands and on the coast of Cyprus. Cervera atlantica is cryptic and photophobic, living under stones in shallow water (usually at 0-2 m) or in crevices and caves in massive intertidal rocks, protected from direct sunlight. Intolerant of rough water, it... |

On the basis of both detailed distributional field studies and morphological analyses, a revision of the polytypic species Albinaria hippolyti from Central and Eastern Crete is presented. True subspecies are distinguished from mere geographic varieties by the presence of narrow hybrid zones. Using this criterion, four adjoining subspecies are recognised: A. h. hippolyti (Boettger, 1878), A. h. aphrodite (Boettger, 1883), A. h. holtzi (Sturany, 1904) and A. h. harmonia subspec. nov. Additionally, two geographically isolated and conchologically distinctive forms are also treated as subspecies: A. h. arthuriana (Boettger, 1878) and A. h. asterousea subspec. nov. The geographical distribution and variability of each subspecies is described in detail. A. h.... |

On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range. This allows new estimations for the... |

The southern Chilean archipelago and fjordland (41-52° S) thus far is very poorly investigated also with regard to its nudibranch fauna. This study presents the first records of nudibranchs from remote islands of the Chonos archipelago exposed to the open Pacific. Collecting data and some biological observations are given for the doridoidean Archidoris fontaini, Diaulula punctuolata and Rostanga pulchra. Taxonomically relevant external and radular characters of R. pulchra are redescribed and compared with literature data on conspecifics from Argentina and California. The bipolar, cold-water adapted R. pulchra is critically compared with the western Atlantic, warm-water adapted R. byga. New distributional data indicates that the Chiloé Island area (41-43°... |

The majority of zoogeographic studies along the Chilean Pacific coast have focused on benthic organisms and oceanographic conditions are considered the main factors influencing their distributions. Herein we examined the geographic distribution of pelagic barnacles of the family Lepadidae collected from floating macroalgae at seven sampling areas between 23 and 50° S. Four species were encountered and they are briefly described herein. The most abundant northern species was Lepas anatifera, and it diminished in abundance towards the south (33° S). Moreover, this species was not found in waters with a sea surface temperature (SST) of less than ~18 °C. Lepas australis, primarily a circumpolar West Wind Drift species, diminished in abundance towards the north... |

The structure of estuarine fish assemblages at temperate latitudes in Patos Lagoon (32º05'S, 52º04'W), Rio Grande do Sul, Brazil and York River (37º17'N, 76º33'W), Virginia, USA was compared using mid and late 1970's data from bottom trawl collection to investigate whether geographically isolated fish assemblages have similar ecological structure given similar latitudinal positions on the warmtemperate southwestern and northwestern Atlantic regions, respectively. Since estuarine species often exhibit an ontogenetic shift in habitat requirements or preferences we examined Capture per Unity of Effort by size class (CPUE-SC) and split species into "size ecological taxa" (SET) for analysis. The use of CPUE-SC also allowed the abundance of a SET to be computed... |

The Atlantic Forest is one of the priority areas for conservation in the world, since exhibits an overwhelming biodiversity of species. Among this biome stands the biogeographic unit located north of San Francisco River, which extends from the state of Alagoas to Rio Grande do Norte. On this portion of Atlantic Forest some isolated fragments of humid forests can be found, inserted in the arid Caatinga, known as Brejos de Altitude or Brejos Nordestinos. There is a total of 43 Brejos distributed in the states of Ceará, Rio Grande do Norte, Paraíba and Pernambuco and with the exception of some humid enclaves in the state of Ceará, the snake fauna of these areas are poorly known. Thus, our aim is to evaluate the current status of the snakes that inhabited... |

Chapada Diamantina is located in central Bahia state, and has a large diversity of habitats, including important transitional areas, but has remained largely unstudied until now. In the present study we list the non-flying mammals of Chapada Diamantina National Park and surroundings. We captured only small non-volant mammals, medium and large mammals were assessed through indirect evidences (tracks and marks) and interviews. We recorded 58 species and 47 genera from seven Mammalian orders. Seven species are included in the list of endangered Brazilian species by IBAMA and IUCN; and other seven are classified as data-deficient. Species richness of small mammals was equivalent among sampled habitats, but species composition varied among habitats (10 in... |
