Modificação ao método de Bray para avaliar a fertilidade do solo

Neste trabalho é apresentada uma modificação ao método de BRAY (1948) para se construir uma curva de calibração de nutrientes disponíveis no solo. Basicamente, trata-se de se estimar o valor da constante da equação de Mitscherlich, na forma linear, por meio de regressão linear e com esse valor construir uma curva de calibração.

Influência do ciclo lunar na captura de Aedes scapularis (Diptera, Culicidae) na Mata Atlântica do Paraná

From October 1995 to January 1996 Aedes (Ochlerotatus) scapularis (Rondani, 1948) was studied in a small area of the Atlantic Forest, Serra do Marumbi, Morretes, Paraná, Brazil. Adults were captured with Shannon light traps for 48 nights, representing 12 nights for seven time intervals. Traps were operated from dusk to dawn. The influences on flight activity of the lunar phase, ambient temperature, relative humidity, and rainfall were analyzed. Ae. scapularis had a flight behaviour different in each of the four lunar phases. In relation to flight period, the species showed higher activity during the first three lunar intervals. Among the climatic variables, temperature and relative humidity positively influenced flight activity during the night.

Rejanellus, a new genus of Thomisidae (Araneae, Stephanopinae)

A new genus, Rejanellus, type species Onocolus venustus Bryant, 1940, is established for four species of spiders of the subfamily Stephanopinae from Cuba and Haiti. The presence of dorsal tubercles on the male carapace is a possible synapomorphy for the genus. The four known species by now Onocolus venustus Bryant, 1948, O. pallescens Bryant, 1940, O. granulata [sic] Bryant, 1940 and Epicadus mutchleri Petrunkevitch, 1930 are transferred to the new genus. All species are redescribed and illustrated.

Ostracodes (Crustacea) from Cananéia-Iguape estuarine/lagoon system and geographical distribution of the mixohaline assemblages in southern and southeastern Brazil

The ostracode assemblages from Cananéia-Iguape estuarine/lagoon system (southernmost State of São Paulo) are here discussed in detail for the first time. Thirty-four sites, approximately 1 km equidistant, were sampled along the system, including the Cananéia Sea, Pequeno Sea, Cubatão Sea, Ribeira de Iguape River and Itapitangui River. The ostracodes throughout this area have poor assemblages, with a total of 662 specimens of dead and living organisms. The majority of the ostracode fauna is composed of euryhaline species, as follows: Cyprideis multidentata Hartmann, 1955 (174 specimens), Minicythere heinii Ornellas, 1974 (54 specimens), Tanella gracilis Kingma, 1948 (96 specimens) and Whatleyella sanguinettiae Coimbra, Carreño & Ferron, 1994 (226 specimens). Although there are few studies on the Brazilian mixohaline ostracode faunas, including the euryhaline marginal marine taxa, the published data show that the group is best known in the south and southeast regions. Based on this review and with the new data presented in this paper, the geographical distribution of eight mixohaline key species in southern and southeastern Brazil is also discussed.

Novo gênero Neotropical de Spintharinae (Araneae, Theridiidae)

Neopisinus gen. nov. é proposto com designação da espécie-tipo Neopisisnus fiapo sp. nov., com base em ambos os sexos, do Rio Grande do Sul, Brasil. Neopisinus distingue-se de todos os gêneros de Spintharinae pelo palpo do macho com enorme condutor trífido, com duas projeções afiladas e uma com ápice bifurcado; pela forma característica da apófise tegular de theridioideos com um lobo terminal e outro dorsal. Nas fêmeas, epígino com aberturas inconspícuas junto à fenda transversal no terço anterior e, internamente, por um espessamento mediano-longitudinal tubular, por onde correm os ductos de copulação em seu percurso inicial. Neopisinus urucu sp. nov. é descrita do norte do Brasil, com base em ambos os sexos. Sete espécies são transferidas de Episinus para Neopisinus: N. bigibbosus (O. P.-Cambridge, 1896), N. bruneoviridis (Mello-Leitão, 1948), N. cognatus (O. P.-Cambridge, 1893), N. gratiosus (Bryant, 1940), N. longipes (Keyserling, 1884), N. putus (O. P.-Cambridge, 1894) e N. recifensis (Levi, 1964). São descritos pela primeira vez o macho de N. longipes e a fêmea de N. recifensis. Novas ocorrências e ilustrações são apresentadas para N. bruneoviridis.

Ostracoda (Crustacea) from the Archipelago of São Pedro and São Paulo, Equatorial Atlantic, with emphasis on a new Hemicytheridae genus

The present study is a further contribution to the systematic knowledge of the shallow water marine ostracodes from the Brazilian oceanic islands. A total of 14 species belonging to 10 genera and eight families is herein identified. One new genus and species are described and illustrated: Berguecythere insularis gen. nov., sp. nov. In addition to this new taxon, the abundant species Loxocorniculum tricornatum Krutak, 1971, widely distributed in recent sediments in the Gulf of Mexico, Caribbean, north and northeast of Brazil and the Rocas Atoll, along with the cosmopolitan tropical ostracode Triebelina sertata Triebel, 1948, were also identified at specific level. The remaining 11 species were left at the genus level, and should provide new species. Ecological, zoo- and paleozoogeographical aspects were also briefly discussed.

Variation of the ichthyofauna along the Goioerê River: an important tributary of the Piquiri-Paraná basin

The construction of reservoirs is considered an important source of impacts on the fish fauna, severely altering the structure of the assemblage. This paper aimed to describe the structure of the fish assemblage of the Goioerê River, determining its longitudinal distribution and patterns of species dominance. The evaluation of its longitudinal variation in the diversity and abundance of the fish assemblage was conducted in July and October 2004 and January and May 2005. The collections were carried out near the headwaters (Gurucaia), middle stretch (Olaria), just above the falls (Paiquerê) and downstream (Foz). Forty-four species were captured. The Gurucaia fish assemblages differed significantly from Olaria, Paiquerê and Foz. The Olaria assemblages differed significantly from the Foz. Gurucaia showed the lowest diversity and abundance of species. Astyanax aff paranae Eigenmann,1914 (78% of the total) was found to be dominant at this site. Almost the same species richness was found at Olaria and Paiquerê, although Olaria had the greatest abundance of individuals. Astyanax aff paranae, Cyphocharax modestus (Fernández-Yépez, 1948) and Astyanax altiparanae Garutti & Britski, 2000 were the top three dominants and comprised over 71% of the total number of fish caught. At Paiquerê, Astyanax altiparanae, Hypostomus aff ancistroides (Ihering, 1911) and Loricariichthys platymetopon Isbrücker & Nijssen, 1979 composed 58% of the catches. Thirty-one species were recorded at Foz, which presented the greatest richness. The most abundant species were Apareiodon affinis (Steindachner, 1879), Galeocharax knerii (Steindachner, 1879) and A.altiparanae, which contributed to 50% of the total catches in this environment.These results record the fish biodiversity and how the community is longitudinally structured in the Goioerê River, and also demonstrate how this type of evaluation is important to understanding the fish community patterns and finding solutions to problems related to the conservation and management of the basin.
