Diversity of the ichthyofauna in the Serra do Mar State Park- Núcleo Santa Virgínia, Sáo Paulo State, Brazil

The aim of this work was to assess and compare the diversity of the ichthyofauna in three headwater rivers of Paraíba-do-Sul basin in the Serra do Mar State Park, Núcleo Santa Virgínia. A total of 1,774 specimens of 16 species of fishes belonging to 6 families were caught. Characiforms were the most abundant fish at all three sites, followed by Cyprinodontiformes, Siluriformes, and Perciformes. The Shannon index (H′), evenness (E), and the Jaccard and Morisita-Horn similarity indexes were low, indicating both low diversity and low similarity of species among the three streams. The values of these indexes should be evaluated according to the biotic and abiotic conditions in each environment. It is clear that in mountain streams of the Atlantic Forest, these low values occur because of the presence of a few abundant and many rare species.

Comportamento de forrageamento do pernilongo-de-costas-brancas, Himantopus melanurus (Vieillot, 1817) (Aves: Recurvirostridae) em Santa Gertrudes, SP, Brasil

The foraging behavior of two White-backed stilts (Himantopus melanurus) was studied in a lake at the municipality of Santa Gertrudes, state of São Paulo, Brazil. The foraging strategies observed were classified in two categories: pluging (65.8% of total maneuvers) and pecking (34.3%). Only in 26.8% of the foraging maneuvers the individuals captured preys (72.9% by plunging and 27.1% by pecking). When comparing both strategies, plunging was successful 29.7% of the times, but pecking only 21.2%. At the study site, individuals foraged only up to 20 m away from the lake margin. The foraging area exploited by the White-backed stilts was estimated in about 720 m 2. Foraging activities lasted since before sunrise until after sunset. © 2006 Instituto de Ciências Biológicas - UFMG.

Características fenotípicas de 44 progênies de espinheira-santa (Maytenus ilicifolia Mart. ex Reiss) cultivadas no município de Ponta Grossa, PR

Due to the confirmation of its medicinal properties, the demand and the area planted with 'espinheira-santa' have been increasing. However, there are no sources of propagation material with known characteristics. Progenies of Maytenus ilicifolia Martius ex Reiss (espinheira-santa), originating from Southern Brazil have been analyzed, and currently comprise a germplasm inventory for the species. Studies included the assessment of in natura growth features (height and production of biomass canopy) and plant chemistry (lignin, phenols and mineral element contents), and targeted the creation of a data base, characterizing populations/progenies to be used in future selection and breeding programs of the species. Among the features assessed, were considered desirable the ones related to productivity (high foliar mass to branch mass ratio) and also the absence of thorns on the leaves. High total phenol and tannin content were observed in all the progenies assessed and these features is desirable as long the absence of toxic effects and preservation of the therapeutic quality of the plant medicinal elements produced can be proved.

The first Triassic lungfish from South America (Santa Maria Formation, Paraná Basin) and its bearing on geological correlations within Pangaea

The Triassic fish faunas of the Southern Hemisphere are only known from a few sedimentary basins and the most productive sites are those from the Karoo Supergroup, in South Africa and the Sydney Basin of Australia. A single lungfish tooth plate ascribed to Ptychoceratodus cf. philippsi was recovered from Late Triassic (Carnian) red beds of southern Brazil and is described herein. This find extends to South America the palaeogeographic distribution of the genus, which occurs in the Early Triassic of Australia and South Africa and the Middle/Late Triassic of Europe and Late Triassic of Madagascar and India. The presence of this dipnoan solely in the uppermost part of the Santa Maria Formation suggests that the migration of Ptychoceratodus towards the Paraná Basin began not before the late Induan/early Olenekian (late Early Triassic). At that time, more humid (monsoonal) conditions prevailed in what is now southern Brazil, compared to semi-arid/desert conditions that dominated the Late Permian and possibly the earliest Early Triassic (the latter presumably not represented in the Paraná Basin). © The Geological Society of London 2008.

Estudos ecológicos em taxocenoses helmínticas de Chaunus ictericus (Spix, 1824) e C. schneideri (Werner, 1894) (Anura: Bufonidae) simpátricos, capturados no distrito de São Cristóvão, Município de Três Barras, Santa Catarina.

Fifty eight Chaunus ictericus and 42 C. schneideri specimens were collected on São Cristóvão district, Três Barras, SC for helminthological studies. Fourteen helminth species were diagnosed, from which only five species were found on both hosts. Chaunus ictericus showed higher values of species richness (2,8448+/-1,1516) and diversity (H = 1,374), with mild dominance (1-D = 0,642, J = 0,5528), in comparison with C. schneideri (0,6428+/-1,007; H = 1,165; 1-D = 0,5822 e J = 0,5985). Also, descriptors of helminthic infection were superior in the former host. Little number of shared species between the analyzed toad species suggests parasitic host-specificity.

Eficiência do protocolo Ovsynch em ovelhas da raça Santa Inês

Twenty six Santa Inês ewes were asigned to three treatments to evaluate the efficiency of the Ovsynch protocol. In the treatment 1 - control (n=8), the estrus was synchronized with sponges containing 60 mg MAP for 14 days. On D14, 300 IU eCG were administered. In treatment 2 (n=9) the Ovsynch protocol was used: 25 μg of GnRH (D0), 37.5 μg of PGF2α (D7) and 25 μg of GnRH (D9). In treatment 3 (n=9) the modified Ovsynch protocol was used: the administration of PGF2α and second GnRH as two days early. Estrus detection was accomplished using teaser. All ewes were mated twice with 12 hours of interval. Pregnancy rate (PR) was evaluated by ultrasonography 30 days after the end of mating. Estrus response was of 88.46% on average, and without differences among treatments (p>0.05). The interval for onset of estrus was greater (p<0.05) in T1, when compared with T2 and T3 (41.31±7.2, 13.37±8.42 and 6.75±5.2 h, respectively). The time of receptivity was greater (p<0.05) in females of T1 and T3 (40.5±6.49 h and 53.68±10.27 h, respectively), compared to females of T2 (34.56±7.2 h). The duration of the induced estrus did not differ significant among treatments (p>0.05). Pregnancy rate was significantly greater (p<0.05) in ewes synchronized with Ovsynch protocol (37.5%, 62.5% and 25% for treatment 1, 2 and 3, respectively). The results show superior efficiency of the Ovsynch protocol, under the experimental conditions.

Avaliação da dinâmica do uso da terra na bacia do arroio Santa Bárbara - pelotas (Brasil), no período de 1953 a 2006

Land use dynamics is a consequence of socioeconomic system cycles. In this context, this work was developed aiming to evaluate land use alterations in Santa Bárbara watershed (Pelotas - Brazil), during 53 years (1953 - 2006), evidencing socioeconomic elements that contributed to this process. For land use dynamic analysis, maps of 1953, 1965, 1995 e 2006 were elaborated. Spatial changes that happened in Santa Bárbara watershed represent a regional process: pasture areas had decrease while culture lands had a gradual increase. This conjuncture is a consequence of the crisis in livestock destined to salted and dried meat production and of the food industry growth in Pelotas that impelled urban expansion, forest area reduction and artificial water reservoirs increase. © Scripta Nova, 2010.
