Abstract: Studies that indicate the presence of Myxomycetes in arid and semi-arid regions of the planet have revealed new taxons and high species diversity. In those environments, the Myxomycetes occupy special microhabitats like those offered by succulent plants. Aiming to expand the knowledge of species that occur in semi-arid environments we investigated the occurrence of Myxomycetes on Cereus jamacaru (mandacaru), Melocactus bahiensis (coroa de frade), Opuntia ficus-indica (palma forrageira) and Pilocereus gounellei (xique-xique) – cacti that compose the natural landscape of the sub-humid (agreste) and semi-arid (sert o) regions of Pernambuco, Brazil. We obtained 158 specimens of Myxomycetes (106 field collections; 52 in moist chamber cultures), representing 16 species distributed in nine genera, with high taxonomic diversity (S/G= 0.63-1.5). All of the identified species are new records for the municipalities studied. Comatricha pulchella, Didymium nigripes and Physarum bogoriense are mentioned for the first time in Caatinga areas in the state of Pernambuco, and Didymium squamulosum and Physarum echinosporum are new records for this biome. Physarum compressum and Badhamia melanospora were the most abundant and frequent species, characterized as constant in the studied myxobiota.

Abstract: the article is a progress report on an on-going research program on slavery in the brazilian northeast. the characteristics of slave labor outside the coastal sugar zone of pernambuco province are investigated. it is found that there were significant slave holdings in the cattle-raising, cotton-growing regions of the province, in the backlands, contrary to a commonly-held belief that those activities were not suited to be performed by slave labor. slave holdings were generally small; and the demographic profile of the slave population was that expected of a labor force productively used by profit-maximizing slave-owners. the proportion of the value of slave holdings in total assets is surprisingly high, and does not tend to decrease after the sharp increase in slave prices in the second half of the nineteenth century. those findings add to the increasing evidence, in the literature, on the importance of small slave holdings in brazil.

Abstract: The poor quality of raw milk is the main problem in dairy industries, once it can directly interfere in the productivity and quality of dairy products. The Pernambuco is not different. located between the Zona da Mata and the Sert o regions, is responsible for a daily milk production of 980,000 liters, and presented an increase of 23% in the last two years. This study aimed the evaluation of the microbiological and physical-chemical quality of raw milk produced in the Agreste region of Pernambuco. Raw milk samples were collected from 53 dairy farms located at the following cities: Saloá, águas Belas, S o Bento do Una and Bom Conselho. For microbiological analysis, all samples were plated for mesophilic aerobes, total coliforms, Escherichia coli and DNase positive staphylococci in specific Petrifilm (3M Microbiology, St. Paul, USA). Listeria monocytogenes and Salmonella spp. were detected using VIDAS system (bioMérieux SA, Marcy l'Etoile, France). Organophosphorade and carbamates were detected by thin layer chromatography. Fat, protein, and lactose contents, total and non-fat solids, and density were obtained by ultrasound method using am automatic milk analyzer (Boecolac-60, Boeco, Hamburg, Germany). In addition, the raw milk samples were evaluated to cryoscopic, California Mastitis Test (CMT), peroxidase, Dornic acidity and Ring-test to brucellosis status of herds. In microbiological analysis, all samples presented high counts of the researched indicators microorganisms. The average of mesophilic aerobes was 1.68 X 107 with 83% of samples over 106. Listeria monocytogenes and Salmonella spp were not found, 47% of the samples were positive for organophosphates and/or carbamates, 67.9% of the samples were positive for CMT and 26.4% for ring test. Thus, only 2 (3.77%) samples were accordance with the established parameters of Instru o Normativa 51.,P. A qualidade do leite é um dos maiores problemas da cadeia do leite no Brasil, interferindo negativamente na produ o e rendimento de derivados. No Estado de Pernambuco, n o é diferente. Sendo o segundo maior produtor do Nordeste, Pernambuco tem sua maior produ o de leite localizada na Regi o Agreste do estado, que fica entre a Zona da Mata e o Sert o. A produ o de leite no Agreste, cresceu 23% nos últimos dois anos, chegando a 980 mil litros/dia. Com o objetivo de avaliar a qualidade microbiológica e físico-química do leite cru produzido nesta regi o, foram coletadas amostras em 53 propriedades rurais, nos municípios de Saloa, águas Belas, S o Bento do Una e Bom Conselho. Enumeraram-se aeróbios mesófilos,

Abstract: this study aimed at evaluating the genetic variability of stylosanthes scabra (alfafa of northeast) populations as a result of the adaptation strategy to different environments from the regions: mata, 'agreste' and 'sert?o' in the state of pernambuco. a great interpopulational variability relative to the germination of non scarified seeds was encountered. populations from 'sert?o', when compared to the ones from 'mata' and 'agreste', showed an inferior germination capacity, suggesting that they acquired favorable conditions to dormancy, probably in response to the environmental adversities in that region.

Abstract: the pedogenesis of planosolic soils, especially of the semi-arid "agreste" region of pernambuco state, brazil, has n ot been properly studied. there are indications and doubts with regard to some aspects such as possible duality or differentiated reworked parent material, total of gains and losses and the relative mobility of the main constituent elements during soil evolution. three soils with strong texture contrast were studied in a toposequence of the region. three soils with a strong textural contrast on a topossequence in the agreste region of the state of pernambuco, brazil were studied. the main objectives of the study were to investigate the compatibility of the soils with the underlying geological material and to quantitatively evaluate losses and gains in the soils during pedogenesis. total chemical analysis, as well as the determination of zirconium and quartz contents were performed for all horizons and parent material to determine a weathering index. it was concluded that the soils were autochthonous with minor indications of surface reworked material. during the weathering process, approximately 50 % of the original soil weight was lost. the mobility of the main elemental constituents decreased as follows: mgo > cao > fe2 o3 > al2o3 > sio2. the sharp textural contrasts between the a and b horizons were not only due to clay eluviation-illuviation (lessivage), but rather a result of other weathering processes.

Abstract: The Agreste region in the state of Pernambuco is characterized by a diversified economy, with different cultivars, besides the daily and beef farms. In 2004 the State produced 398 million liters of milk; it represented 14.7% of the Northeast Region production and 1.7% of the National production. The aim of this work was to characterize the milk properties of the Agreste region of Pernambuco, observing conditions and factors that could interfere with milk quality. In the survey, 41 milk farms were selected in the region. Small milk farms were the most common found, with less than 25 (43.9%) animals in lactation, and 36 (87.8%) farms held a manual milking process. In relation to hygiene practices during milking, 16 (39.0%) of the producers washed the teats before beginning, but only 4 (9.8%) performed pre-dipping and 34 (82.9%) milked in the presence the calf. Only 5 (12%) farms applied some treatment to the water used for cleaning installations and equipment, even the water for human consumption was treated in only 43.9% of the farms. Milk refrigeration was performed in 10 (24.4%) farms in communitarian tanks. As far as animal health is concerned, 39 (95.1%) owners vaccinated for food and mouth disease and 23 (56.1%) for brucellosis, while 10 (24.4%) tested for tuberculosis. Regarding the farms structure the production conditions were precarious, showing the need of improving the structure itself and animal handling. As well as the implementation of Good Manufacturing Practices in the milking process, proper to the local reality. O Agreste pernambucano é caracterizado por uma economia diversificada, com diferentes cultivos, além da pecuária de leite e de corte. Em 2004 o Estado produziu 398 milh es de litros de leite, o que representou 14,7% da produ o da Regi o Nordeste e 1,7% da produ o Nacional. Este trabalho teve como objetivo caracterizar as propriedades leiteiras da regi o Agreste do Estado de Pernambuco, observando condi es e fatores que pudessem interferir na qualidade do leite. Foram selecionadas 41 propriedades leiteiras da regi o. Observou-se o predomínio das propriedades de pequeno porte, com até 25 (43,9%) animais em lacta o, sendo ordenha manual em 36 (87,8%) das propriedades. Em rela o às práticas de higiene na ordenha, 16 (39,0%) dos produtores lavavam os tetos antes da ordenha, mas apenas 4 (9,8%) realizavam pré-dipping e 34 (82,9%) ordenhavam na presen a do bezerro. Apenas 5 (12%) das propriedades realizavam algum tipo de tratamento da água utilizada para higieniza o de instala es e equipamentos, mesmo a água para consumo humano

Abstract: A sarna corióptica é de rara ocorrência em caprinos, no entanto trata-se de uma enfermidade cutanea importante, resultando em perdas econ micas decorrentes do retardo no desenvolvimento dos animais, da perda de peso e do prejuízo à indústria de couro. Desse modo, o objetivo do presente artigo é relatar a ocorrência de um surto de sarna corióptica em um rebanho caprino criado no município de Gravatá (Lat. 08° 12’ 04’’ S e Long. 35° 33’ 53’’ O), regi o Agreste do estado de Pernambuco. Os animais apresentavam extensas áreas de alopecia, eritema, crostas e espessamento da pele na regi o das axilas, peito, ventre e as faces caudal e craniomedial dos membros posteriores, além de intenso prurido. Foi realizado raspado cutaneo e identificado o ácaro Chorioptes bovis spp. PALAVRAS-CHAVES: Caprinos, Chorioptes spp, sarna. Chorioptic mange is of rare occurrence in goats, although it is an important skin disease resulting in economic loss due to the delay in the development of the animals, weight loss and economic losses to the leather industry. Thus, the aim of the present article was to report the occurrence of an outbreak of chorioptic mange in a goat flock reared in the city of Gravatá, (Lat. 08° 12’ 04’’ S and Long. 35° 33’ 53’’ W) in Pernambuco′s Agreste region. The animals showed wide alopecia areas, erythema, crusts and skin thickness in the following areas: armpits, sternum, ventral abdomen, caudal and cranium-medial facets of the hind legs and severe scratching. Chorioptes bovis spp was identified in skin scrapings. KEY WORDS: Chorioptes spp, goats, mange.

Abstract: A principal forma de eros o nas condi es brasileiras é a causada pela energia cinética do impacto das gotas de chuva sobre a superfície do solo, desencadeando o processo de eros o hídrica. Desenvolveu-se o presente trabalho com o objetivo de avaliar o índice de erosividade (EI30) e caracterizar o padr o hidrológico das chuvas do Agreste Central pernambucano, considerando-se uma série de 29 anos de dados, ficando patente que o primeiro semestre do ano é caracterizado pela ocorrência de chuvas de elevado potencial erosivo. O valor do fator "R" da equa o universal de perda de solo para a regi o estudada é de 2.779,79 MJ mm ha-1 h-1. O padr o de chuva de maior ocorrência é o avan ado, seguido do intermediário e atrasado, com 46,57; 36,38 e 17,19% dos totais de chuvas erosivas analisados, respectivamente. N o foram encontradas correla es significativas entre erosividade, coeficiente de chuva e precipita o. The main form of erosion in Brazilian conditions is caused by the kinetic energy of the impact of raindrops on the soil surface, triggering the erosion process. The present study was conducted with the aim to evaluate the erosivity index (EI30), as well as to characterize the hydrological pattern of rainfall in the Pernambuco Central 'Agreste', considering a series of 29 years of data. It was found that the first half of the year is characterized by rain with high erosive potential. The value of the factor "R" in the Universal equation of soil loss for the studied region is 2,779.79 MJ mm ha-1 h-1. The rain pattern of higher occurrence is the advanced, followed by intermediate and delayed, with 46.57; 36.38 and 17.19% of total erosive rainfall analyzed, respectively. There were no significant correlations between erosivity, rainfall coefficient and precipitation.
