Resistência contra ectoparasitas em bovinos da raça Crioula Lageana e meio-sangue Angus avaliada em condições naturais

This study was carried out to evaluate the breed resistance against ectoparasites infestations in Crioula Lageana and crossbred Angus male calves under natural condition. Ten weaned and neutered male calves (6-8 months) of each group were kept together in winter and summer pastures in Monte Castelo, Santa Catarina State. Every 28 days, female ticks (Rhipicephalus (Boophilus) microplus) more than 4 mm long were counted on the right and left side of the body of each animal, as well as the D. hominis nodules. Coat thickness also was measured at each sampling and all animals were classified according coat color. Crioula Lageana group was less infested by D. hominis than crossbred Angus in five times and by ticks in the infestation peak (P<0.05). There were no differences in the distribution of the ticks and grubs between animal body sides. Dark-haired animal in both groups were the most susceptible.

Recuperação de áreas degradadas por erosão hídrica em propriedades produtoras de café nos municípios de Getulina e Vera Cruz - SP

The Paulista West region has suffered through the decades an intense process of deforestation when substituting native areas of Atlantic rainforest and Cerrado by agricultural cultivation, mainly coffee in the 20th century. This occupation process without planning and management of the soil resulted in serious erosion problems. Besides, the soil erosion promoted the reduction of agricultural production and the silting of rivers. This paper aims identify the factors of natural scope (geological, geomorphologic and pedologic characteristics) which participate in unleash of erosion process in two agricultural properties producers of coffee in order to apply mechanical techniques of recovery in erosive focuses of furrow and ravine kinds. One of the properties is at the city council of Getulina, located on the sandstones of Adamantina Formation; the other is at the city council of Vera Cruz, located on the sandstones of Marília Formation. However, taking into consideration the analysis of the natural dynamics, they are not enough to explain the complexity of the phenomena which are processed in the geographic space. It made indispensable the incorporation of socio-economic factors, such as the use and occupation process of the soil considering the society as landscape transformers. In order to better understand the importance of each one of the elements that contributes to the unleash of the studied erosions, it was collected soil samples in the areas, general descriptions and texture and morphologic analysis. Finally, it was elaborated the maps of the use and occupation of the soil and the vegetal coverage surrounding the properties studied. It was observed in the rural property of Getulina the substitution of the coffee by pasture that finds degraded. It, in addition to the cattle stomp, which changed the texture and density characteristics among the soil horizons, and the concentration of superficial water flow intensified the occurrence of ...

Análise paleogeográfica evolutiva da região do Parque Estadual da Ilha do Cardoso (PEIC), litoral sul de São Paulo, como subsídio a ações de planejamento e conservação ambiental

Cardoso Island, settled in the south of paulista region, is characterized by its ecological importance due to the great biodiversity of Mata Atlântica and for accommodating several kinds of ecosystems as mangroves, which were considered by UNESCO as human natural ownership. The mangroves are among the most important marine ecosystems, known as warranty of biological productivity and diversity and supply of food and economical resources to the local population. Although the island has been transformed in a state park for preservation, it hasn’t become free from environmental impacts made by antropical activities. This way it was proposed a rebuilt of an evolutionary process in the region, having as an objective to subsidize programs of environmental conservation and planning , aiming to a sustainable development. For this it was used a isobasis methodological analyses where by the drainage channels and its confluences makes relative maps to the different base levels represented by the isobasis, characterizing itself by an attempt to rebuilt the preterit local landscape. There were elaborated eight maps referring to four orders of confluences met in the region of Cardoso Island and round it where you can conclude it is about an appropriate methodology to rebuilt preterits environments that specially aim to actions of environmental planning and conservation.

Marcadores de Microssatélites para estudos de conservação da Raia-viola Rhinobatos percellens (Chondrichthyes, Rhinobatidae)

A exploração pesqueira, tanto artesanal quanto industrial, se constitui na maior ameaça à biodiversidade dos elasmobrânquios. Em escala mundial, o manejo adequado destes recursos é dificultado pela escassez de informações básicas sobre a dinâmica populacional destes organismos. A captura comercial de elasmobrânquios tem alcançado números alarmantes, com a inclusão de diversas espécies nas listas de risco de extinção nacional e também internacional. A identificação e a conservação de estoques geneticamente diferenciados e adaptados ao seu habitat, representam um ponto fundamental para o setor pesqueiro, pela sua relação direta com a produtividade total e o uso sustentável dos recursos. Entre as raias marinhas, a família Rhinobatidae é representada pelos gêneros Rhinobatos, Zapteryx, Trygonorhina e Aptychotrema, sendo registrada a ocorrência da espécie Rhinobatos percellens no Oceano Atlântico adesde as Antilhas e Panamá, Venezuela, Jamaica, Brasil, Uruguai, até a Argentina. No presente trabalho foram desenvolvidos marcadores moleculares do tipo microssatélites para raiaviola, Rhinobatos percellens, para serem utilizados em estudo populacionais. Cinco locus polimórficos foram isolados utilizando um protocolo de enriquecimento. Nos experimentos, foram testados 13 pares de primers, sendo 10 isolados no presente trabalho e 3 isolados para a espécie de tubarão azul (Prionance glauca). Dos primers isolados em Rhinobatos percellens, 5 são polimórficos, 2 monomórficos e 3 apresentaram bandas muito fracas, enquanto os primers testados de tubarão azul mostraram-se monomórficos. Todos os locus estão em equilíbrio de Wardy-Weinberg, exceto o RVA9 (de R. percellens). Os locus polimórficos apresentam de 3 a 6 alelos por locus e heterozigosidade média esperada de 0.62. Considera-se que estes marcadores polimórficos...(Resumo completo, clicar acesso eletrônico abaixo)

A importância da reserva legal para a preservação da fauna e flora existentes nas propriedades rurais de Botucatu

The main objective of this study was elaborating a diagnosis of technical conditions of Legal Reserves situation on the rural properties in Botucatu. In addition, considering the characteristics of fauna and flora and the economic aspects of these areas, it was presented alternatives to encourage the correct implantation and the effective preservation of the Legal Reserves. Because these areas contribute to the maintenance of local biodiversity and to availability of environmental services essential for all living creatures. In this study it was observed the presence of native vegetation in 13% of the rural properties’ areas in Botucatu, it is therefore necessary the recovery (reforestation) of 7% of all the rural properties’ areas, to be achieved the 20% of native vegetation (minimum area to be preserved as Legal Reserve, as disposed in Federal Law nº 12.651/12) on rural properties. A viable and significant alternative for recovery these areas, reinforced by the new forestry law, is the practice of sustainable management, that must be carried in harmony with conventional farming practices existing in the remaining areas of rural properties
