Condition factor of Goniopsis cruentata (Crustacea, Brachyura, Grapsidae) from Mundaú/Manguaba estuarine complex, Alagoas, Brazil
Provedor de dados: 76
Autores: Lira,José J. P. R.; Calado,Tereza C. S.; Araújo,Marina S. L. C.
The condition factor is a parameter which acts as a general indicator of the "well-being" of a species, and it can be obtained through the analysis of width vs. weight relationships. The present work aims to investigate size vs. weight relationship and the condition factor of the crab Goniopsis cruentata (Latreille, 1803). The study area was the Mundaú/Manguaba estuarine complex, Maceió, state of Alagoas, Northeast Brazil. Samplings were monthly accomplished from August 2007 to July 2008. A total of 626 individuals were analyzed, being 309 males and 317 females. Males were larger and heavier than females, what is expected in many brachyuran. The growth was positive allometric to both males (b = 3.42) and females (b = 3.30), not obeying the "cube law". The...

Provedor de dados: 84
Autores: Campos,Cláudia Bueno de; Esteves,Carolina Franco; Dias,Douglas de Matos; Rodrigues,Flávio Henrique Guimarães.
ABSTRACT The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order to characterize the community of mammals of this region, considering species richness, we installed 80 camera-trap stations. With a sampling effort of 10,370 camera-days we recorded 28 species (22 wild and six domestic). Opportunistically, we recorded four mammals, resulting in a total richness of 32 species, five of which are included in the global list of endangered species, and seven in the national...

Brazil’s Minimum Price Policy and the Agricultural Sector of Northeast Brazil
Provedor de dados: 31
Autores: Fox,   Roger W.
The effect pubic policy has on the relative prices of agricultural commodities is a controversial topic in developing countries, developed countries, and international agencies alike. The controversy arises as a result of a lack of understanding of the conflicting effects of relative price changes on various producer and consumer income classes and, when the effects are understood, as a result of emphasizing the value class over another. Unfortunately, there are a few case studies available on the workings of the many and varied approaches taken to agricultural price policy in the developing countries. IFPRI was delighted to take advantage of Roger Fox’s availability to make this study of the minimum price program of Brazil, as it applies to the...

Seasonal variability of planktonic copepods (Copepoda: Crustacea) in a tropical estuarine region in Brazil
Provedor de dados: 103
Autores: Dias,Cristina de Oliveira; Araujo,Adriana Valente de; Bonecker,Sérgio Luiz Costa.
The Caravelas River estuary and adjacent coastal region were studied during the rainy and dry seasons of 2003-2004 to assess the copepod community structure. Abiotic and biotic parameters were measured, and the total density, frequency and percentage of copepod taxa were determined for each sampling period. Copepod densities showed significant differences between sampling periods, with higher densities in the rainy seasons (Mean: 90,941.80 ind.m-3; S.D.: 26,364.79). The sampling stations located to the north and south, in the coastal region adjacent to the Caravelas River estuary presented the lowest copepod density values. The copepod assemblage was composed mainly of estuarine and estuarine/coastal copepods. The seasonal variations in temperature and...

Do euglossine males (Apidae, Euglossini) leave tropical rainforest to collect fragrances in sugarcane monocultures?
Provedor de dados: 104
Autores: Milet-Pinheiro,Paulo; Schlindwein,Clemens.
Euglossine bees are known to be long-distance pollinators in tropical rainforests. But there is controversy concerning to the flight ranges of these bees between forest fragments. In an isolated fragment of Atlantic Rainforest in Pernambuco, NE Brazil, surrounded by sugarcane monocultures, it was examined if euglossine males leave closed rainforest to collect fragrances. In a straight-line transect leading from forest into a sugarcane plantation, euglossine males were simultaneously captured by scent baits at seven distinct points: inside the forest, forest edge, outside the forest in the sugarcane fields at distances of 10 m, 50 m, 100 m, 250 m and 500 m from the forest edge. A total of 945 euglossine bees of 16 species were recorded. The results...

Autores: Moura,Ariadne do Nascimento; Bittencourt-Oliveira,Maria do Carmo; Dantas,Ênio Wocyli; Arruda Neto,João Dias de Toledo.
The aim of this study was to characterize phytoplankton associations, as well as discuss controlling factors determining algal dominance in a eutrophic tropical reservoir, Mundaú, Pernambuco, Brazil. Water samples were collected during the dry period (January/2005) and the rainy period (June/2005). The samples were collected from both limnetic and littoral regions, and the phytoplankton assemblages identified from current literature after preservation in formaldehyde 4%. At the same time as sampling was done, in situ measurements of water temperature, transparency, dissolved oxygen, and pH were also taken. Total phosphorus, total nitrogen concentration and the Trophic State Index were subsequently determined in the laboratory. Phytoplankton density (ind....

Mineral chemistry of tantalate species new in the Borborema Pegmatitic Province, Northeast Brazil
Provedor de dados: 42
Autores: Beurlen,Hartmut; Soares,Dwight R.; Thomas,Rainer; Prado-Borges,Lucila E.; Castro,Cláudio de.
Tantalate samples, supposedly of the columbite group, were collected in the Borborema Pegmatitic Province, aiming to test the Mn/(Mn+Fe) and Ta/(Ta+Nb) ratios as geochemical indicators of pegmatite fractionation. Surprisingly, preliminary microprobe data allowed recognizing some species, so far unknown in the Province, namely titanian ixiolite, fersmite, brannerite, strüverite, natrobistantite, plumbo- and stibiomicrolite, plumboand uranpyrochlore. The identification of these exotic tantalates with unusual composition, in addition to its distribution in several pegmatites, far from the classical Alto do Giz and Seridozinho pegmatites, indicate that the elevated degree of fractionation is not restricted to these two occurrences but may be reached in other...

Abundance and instantaneous transport of Petrolisthes armatus (Gibbes, 1850) planktonic larvae in the Catuama inlet, Northeast Brazil
Provedor de dados: 42
Autores: Melo Júnior,Mauro de; Schwamborn,Ralf; Neumann-Leitão,Sigrid; Paranaguá,Maryse N.
The influence of tidal and diel changes on the exchange of Petrolisthes armatus planktonic larvae was studied at the Catuama inlet, which represents an intermediate system of marine and estuarine environments in the Northeast Brazil. To characterize the larval abundance and vertical distribution, samplings were carried out in August 2001 at neap tide and 3 stations, with 3 hours interval over 24 hours. Samples were taken at three or two depths at each station, with a plankton pump coupled to a 300 µm mesh size net. Petrolisthes armatus zoea I and II showed a mean of 26.3 ± 83.6 and 12 ± 38.8 ind m-3, respectively. During flood tides, the larvae were more concentrated in the midwater and surface, which avoided the transport to internal regions. In contrast,...

Deficit of sand in a sediment transport model favors coral reef development in Brazil
Provedor de dados: 42
Autores: Bittencourt,Abílio C.S.P.; Leão,Zelinda M.A.N.; Kikuchi,Ruy K.P.; Dominguez,José M.L.
This paper shows that the location of the shoreface bank reefs along the northeastern and eastern coasts of Brazil, in a first order approximation, seem to be controlled by the deficit of sediment in the coastal system. The sediment transport pattern defined by a numerical modeling of wave refraction diagrams, representing circa 2000 km of the northeastern and eastern coasts of Brazil, permitted the regional-scale reproduction of several drift cells of net longshore sediment transport. Those drift cells can reasonably explain the coastal sections that present sediment surplus or sediment deficit, which correspond, respectively, to regions where there is deposition and erosion or little/no deposition of sand. The sediment deficit allows the exposure and...

ABSTRACT Drought is a natural and recurrent phenomenon. It is considered ‘a natural disaster’ whenever it occurs in an intensive manner in highly populated regions, resulting in significant damage (material and human) and loss (socioeconomic). This paper presents the efforts developed to monitor the impact of drought in the semiarid region of Northeast Brazil. In this scope, information from different sources is compiled to support the evaluation and identification of impacted municipalities, with the main objective of supporting emergency actions to mitigate their impact. In the semiarid region of Brazil there are frequent occurrences of dry periods during the rainy season, which, depending on the intensity and duration, can cause significant damage to...

Climatic characteristics of the 2010-2016 drought in the semiarid Northeast Brazil region
Provedor de dados: 42
Autores: MARENGO,JOSÉ A.; ALVES,LINCOLN M.; ALVALA,REGINA C.S; CUNHA,ANA PAULA; BRITO,SHEILA; MORAES,OSVALDO L.L.
ABSTRACT This study discusses the climatological aspects of the most severe drought ever recorded in the semiarid region Northeast Brazil. Droughts are recurrent in the region and while El Nino has driven some of these events others are more dependent on the tropical North Atlantic sea surface temperature fields. The drought affecting this region during the last 5 years shows an intensity and impact not seen in several decades in the regional economy and society. The analysis of this event using drought indicators as well as meteorological fields shows that since the middle 1990s to 2016, 16 out of 25 years experienced rainfall below normal. This suggests that the recent drought may have in fact started in the middle-late 1990s, with the intense droughts...

Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. We conducted a 30-day inventory of the herpetofauna of the Catimbau National Park, Pernambuco State, Brazil. Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity. We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated. We attempted to show the great potential of Catimbau National...

Provedor de dados: 58
Autores: Bezerra,Cristianne S.; Lima,José M.C.; Vilar,Janaina L.; Moreira,José L.B.; Frota,Cristiane C.
The hepatitis C virus (HCV) is classified into six different genotypes and their distribution is different throughout the world. Epidemiologic studies are important to determine several characteristics of the virus, as well as the disease. This study analysed the prevalence of HCV and its genotypes among patients from a leading hospital in Ceará, which is located in Northeast Brazil. A total of 119 anti-HCV-seropositive patients, each having previously completed a questionnaire about risk behaviours related to HCV infection were tested for HCV infection using a qualitative HCV polymerase chain reaction (PCR) assay and genotyping by restriction fragment length polymorphism (RFLP). The detection was based on amplifying of the non-coding 5' region. Of the 119...
