Nuevo registro de Paralomis otsuae Wilson, 1990 (Decapoda, Anomura, Lithodidae) en la costa centro-sur de Chile
Barría,Erwin M; Jara,Carlos G;
Investigaciones marinas , 2005, DOI: 10.4067/S0717-71782005000100009
Abstract: a report is made on the capture of five male specimens of paralomis otsuae wilson on the continental slope off the coast of corral, chile (39o50`s). this finding significatively extends the southern latitudinal geographic range of the species. the specimens measured between 89 and 115 mm in cephalotoracic length excluding the rostral spine, and between 94 and 118 mm in cephalothoracic width excluding the lateral spines. some morphological characteristics and morphometric dimensions were noteworthy. discussion is presented on the significance of the characteristics of this species and its' geographic distribution

Ocorrência de Aedes (Stegomyia) albopictus (Skuse) em área urbana do estado do Tocantins
Balestra, Rafael A.M.;Pereira, Rosany K. de O.;Ribeiro, Maria J. de S.;Silva, Júlia dos S.;Alencar, Jeronimo;
Neotropical Entomology , 2008, DOI: 10.1590/S1519-566X2008000200020
Abstract: this is the first report of the presence of aedes albopictus (skuse) in the tocantins state, brazil, in urban area of the mateiros city. immature specimens (aquatic stages) of this vector were collected in water reservoirs, treeholes, old tires and others. the existence of ae. albopictus in the metropolitan area poses a potential risk for the interaction of this mosquito species with the urban human population.

Caires, Rodrigo Antunes;Figueiredo, José Lima de;Bernardes, Roberto ávila;
Papéis Avulsos de Zoologia (S?o Paulo) , 2008, DOI: 10.1590/S0031-10492008001900001
Abstract: new data of the geographical distribution of several species of teleost fishes assigned to the brazilian coast, including some species never previously recorded, are presented. the serranids pseudogramma gregoryi (recorded from florida to venezuela), and plectranthias garrupellus (recorded from north carolina to caribbean sea) were found, respectively, in coast of ceará and in southeastern and southern brazilian coast. the two sole records the family caristiidae in brazilian coast are mentioned and discussed, and are given herein the first accounts of the species enchelycore carychroa (muraenidae) and chilomycterus antillarum (diodontidae) from southeastern brazilian coast, and of neobythites brasiliensis (bythitidae) from northeastern brazilian coast. we have also discussed the northernmost occurrence of calamus mu (sparidae), a species formerly circumscribed to the region between espírito santo and s?o paulo, and additional records of bascanichthys paulensis (ophichthidae), nezumia aequalis (macrouridae), antigonia combatia (caproidae) and notolycodes schmitti (zoarcidae).
Range extension for Thomas' Mastiff bat Eumops maurus (Chiroptera: Molossidae) in northern, central and southeastern Brazil
Sodré, Miriam M.;Rosa, Adriana R. da;Gregorin, Renato;Guimar?es, Maricélio M.;
Revista Brasileira de Zoologia , 2008, DOI: 10.1590/S0101-81752008000200027
Abstract: thomas' mastiff bat, eumops maurus (thomas, 1901) is known from northern south america in ecuador, venezuela and guiana and so it probably occurs in brazil, yet it has not been reported. here, we present the first record for e. maurus in brazil. captures were from the brazilian states of tocantins and goiás (northern and midwestern cerrado region of the country), and s?o paulo (southeastern brazil, atlantic forest). in the first two locations, all bats were roosting in palm leaves while in the later location, a single animal was found alive in a 15th-storey apartment in the city of s?o paulo. this bat inhabits savannas with swamps dominated by the palm mauritia flexuosa (buriti) and gallery forests. this record is the first of e. maurus in an urban area. brazilian specimens are apparently larger than those from northern south america.

First records of Synoeca septentrionalis Richards, 1978 (Hymenoptera, Vespidae, Epiponini) in the Brazilian Atlantic Rain Forest
Rodolpho Menezes,Sergio Andena,A.F. Carvalho,M. A. Costa
ZooKeys , 2011, DOI: 10.3897/zookeys.151.1882
Abstract: Nests of Synoeca septentrionalis were collected in two Brazilian Atlantic Rain Forest localities (Itabuna and Santa Terezinha, in the state of Bahia and Alfredo Chaves in the state of Espírito Santo). S. septentrionalis was previously recorded only from Central America and northwestern South America. This finding extends its geographical distribution to Northeast and Southeast regions of Brazil, and represents the first record for S. septentrionalis in the Brazilian Atlantic Rain forest, raising to three the number of Synoeca species known from Bahia State.

Abstract: Natural processes in ecosystems shows significant variations in species richness with regular cycles that can be altered by natural or anthropogenic activities; the present research was in order to understand on some of these variations. The objectives were: 1) determine the species richness of rocky intertidal mollusks; 2) track their geographical distribution at State level; and 3) determine the changes in species richness as a result of rainfall on an annual cycle. For these purposes it was sampled in March, June, September and December 2005, the sampled area was 20 m2for each collecting site; the sampling unit was a PVC rectangle frame one by two meter per side. The mollusks found within the sampling units were collected, identified and counted. The species distribution was analyzed by sites and regions, considered species richness per season, and the distributional patterns by rainy season historical records. A total of 62 mollusks species were found, its richness associated with substrate stability and wave intensity on each site, Gastropods had the highest species richness. When analyzing the regional distribution and sites, it was found a pattern of species richness roughly constant in the proportion of species with wide distribution (generalists) versus those of restricted spatial representation (specialists). Gastropods had the highest number of species with restricted spatial representation. Seasonal rainfall differences did not quantitatively altered on the overall the species of mollusks in the rocky intertidal sampled zone however, in the analysis per Class, Gastropoda indicated changes in species richness influenced by rainfall, which were not observed in Bivalvia and Polyplacophora, suggesting that those changes might depend on adaptive processes or the lack of adaptation of gastropod species to the characteristics of the rocky intertidal habitat

Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.65040
Abstract: Ticks are regarded as the most relevant vectors of disease-causing pathogens in domestic and wild animals. The diversity of Ixodidae is known for a very small number of genera.Ixodes are represented by 26 species, and in 2007 the first reported ticks vectors in Mexico for the causal agent of Lyme disease. Recent rise in tick-borne disease in many parts of the world is a phenomenon in need of an explanation. The main objective of the present work was to map at a regional scale (1:2,000,000) of the distribution of ticks of the family Ixodidae that are potentially present on the wild fauna of state of Michoacan, Mexico. We compiled all available literature on ticks at a national level together with complete cartographic and bibliographic georeferenced information of the distribution of hosts in order to build a spatial database in ArcView 3.3. The results indicated that the wild fauna in the state’s territory could potentially include 31 species of ticks of Ixodidae. The map of potential species richness of ixodid ticks on the wild fauna of the state can be categorized into five classes of species richness. The highest potential concentration of ixodid species on wild fauna occurs in the volcanic area of Pico de Tancítaro.
