Koening, Maria Luise;Lira, Cynthia Gomes de;
Acta Botanica Brasilica , 2005, DOI: 10.1590/S0102-33062005000200022
Abstract: this work presents the species and the distribution of the ceratium schrank (pyrrophyta) from coastal and oceanic waters of pernambuco state. sampling were performed aboard the research vessel victor hensen, during the jops ii project, leg 5, from february 25 to march 3, 1995. collections were carried out in 34 stations, distributed in 7 profiles perpendicular to the coast, with 14 stations located at the neritic region and 20 at the oceanic one. samples were collected with a bongo net, 64 mm and fixed with 4% neutralized formaldehyde. fifty eight specific and underspecific taxa were identified, outranking as the most frequentc. contortum var. karstenii (97%), c. macroceros var. macroceros (82%), c. teres, c. euarcuatum (79%), and ceratium tripos subsp. tripos (73%) the last one being the only abundant subspecies. 56% of the taxa ocurred at the neritic and oceanic region. the oceanic region presented 42% of species per sample analised.
Attaining the minimum target of resolution WHA 54.19 for schistosomiasis control in the Rainforest Zone of the state of Pernambuco, Northeastern Brazil
Favre, Tereza C;Ximenes, Ricardo AA;Galv?o, Aline F;Pereira, Ana Paula B;Wandereley, Tereza N;Barbosa, Constan?a S;Pieri, Otávio S;
Memórias do Instituto Oswaldo Cruz , 2006, DOI: 10.1590/S0074-02762006000900020
Abstract: resolution 19 of the 54th world health assembly (wha-54.19) urged member nations to promote preventive measures, ensure treatment and mobilize resources for control of schistosomiasis and soil-transmitted helminthiases (sth). the minimum target is to attend 75% of all school-age children at risk by year 2010. the brazilian ministry of health (moh) recommends biennial surveys of whole communities and treatment of the positives through the schistosomiasis control program within the unified health system (pce-sus). however, by 2004 the pce-sus had covered only 8.4% of the 1.2 million residents in the rainforest zone of pernambuco (zmp). six of the 43 municipalities still remained unattended. only three of the municipalities already surveyed reached coverage of 25% or more. at least 154 thousand children in the 7-14 years old range have to be examined (and treated if positive) within the next five years to attend the minimum target of the wha 54.19 for the zmp. to make this target feasible, it is suggested that from 2006 to 2010 the pce-sus actions should be complemented with school-based diagnosis and treatment, involving health and educational organs as well as community associations to include both children in schools and non-enrolled school-age children.

Fischer, AF.;Hazin, FHV.;Carvalho, F.;Viana, DL.;Rêgo, MG.;Wor, C.;
Brazilian Journal of Biology , 2009, DOI: 10.1590/S1519-69842009000500023
Abstract: one hundred seventeen specimens of sharks were caught along the coast of pernambuco state, northern brazil, between may 2004 and may 2007, among which 86 were blacknose sharks, carcharhinus acronotus, enabling a more detailed study of the species. blacknose sharks were caught in the 2 study areas along the boa viagem/piedade and paiva beaches, accounting for the highest relative abundance among the species caught (73.5% of total). potentially dangerous sharks, tiger and bull sharks, were also caught in the same areas, whereas hammerhead and blacktip sharks were only captured off boa viagem/piedade. concerning the blacknose shark, the total length (tl) ranged from 39.0 to 180.0 cm. among the 38 females analysed, 32 were juveniles, 11 were maturing, 2 were pre-ovulatory and 21 were pregnant. sexing was possible for 75 of the 83 embryos, 38 of which were males and 37 were females, with a sex proportion of 1:0.9 and total length ranging between 6.4 and 63.5 cm. ovarian fecundity ranged from 5 to 10 and uterine fecundity from 1 to 3, with an estimated gestational period of 9 months. among the 48 males, 6 were juveniles and 42 were adults. both males and females seem to reach sexual maturity at about 105.0 cm tl. among the 86 stomachs analysed, only 22.1% had contents, with teleosts as the most frequent item.
Padr?es de distribui??o das espécies de Paspalum L. (Poaceae: Panicoideae: Paniceae) ocorrentes em Pernambuco, Brasil
Maciel, Jefferson Rodrigues;Oliveira, Regina Célia de;Alves, Marccus;
Brazilian Journal of Botany , 2009, DOI: 10.1590/S0100-84042009000300017
Abstract: with an aim to contribute to our knowledge of distribution patterns of paspalum species, this study examines the distribution of the species that occur in pernambuco. in order to do this, extensive reviews of the literature, of specimens deposited in several herbaria, and of databases available on the internet, in addition to collections made in the state of pernambuco were performed. the 31 species analyzed were classified into two distribution patterns: broad, with 29 species and restricted, with two species. the species with restricted distribution are found in the northeast region of brazil, with one endemic to the semi-arid domain and the other until now only recorded from the atlantic coast of brazil. the broad distribution pattern can be subdivided into two groups, continuous and disjunct, which can be subsequently classified into three subgroups: american, central-south american, and south american. the importance of this analysis for a better understanding of flora of pernambuco origins is also discussed.
Estrutura e organiza??o trófica da ictiofauna de águas rasas em um estuário tropical
Paiva, Andréa C. G. de;Chaves, Paulo de Tarso da C.;Araújo, Maria E. de;
Revista Brasileira de Zoologia , 2008, DOI: 10.1590/S0101-81752008000400010
Abstract: the goals of the present study were: 1) to test whether the shallow water ichthyofaunal diversity in the formoso river (pernambuco) varies between the upper and lower estuarine zones and between the dry and rainy season; and 2) to assess spatial and temporal shifts in their trophic categories. the fishes were collected bimonthly using beach seine. a total of 5,475 individuals were analyzed, belonging to 78 species, of which 51.3% were of reef origin. carangidae and gerreidae had the highest diversity, whereas clupeidae, engraulidae and gerreidae were the most abundant. among the dominant species (89%), rhinosardinia amazonica was particularly common (36%). most of the species were predators (75%), including species with carnivorous feeding habits of the 2nd order (37.5%). the only statistically significant difference in diversity occurred between the lower and upper estuarine zones, being higher in the former. this is probably due to the higher morphological complexity, to the larger proportion of rhizophora mangle (shelter and refuge for several fishes), and to the mud sediment that makes this a more productive area. the trophic contribution factor (fct) for the debris was higher in the upper estuarine zone, where there is a higher rate of silt and clay. this tcf for primary production was higher in the middle estuarine zone, where there is higher phytoplankton biomass. most species were in the young ecophase, corroborating the importance of shallow waters in this tropical estuary as a natural nursery and shelter for several fish of ecological and economical importance.

Albuquerque, Cleide Maria Ribeiro de;Porto, Tiago Jord?o;Amorim, Maria Lucineide Porto;Santana Neto, Pedro de Lima;
Revista da Sociedade Brasileira de Medicina Tropical , 2009, DOI: 10.1590/S0037-86822009000200023
Abstract: this paper presents the first reports on scorpion accidents caused by tityus pusillus (buthidae). the accidents took place within the home environment, in rural areas located in the municipalities of paudalho and s?o louren?o da mata, pernambuco, brazil. the two cases described (a child and a pregnant woman) were classified as mild and moderate, respectively. the clinical symptoms presented were local disorders (pain and paresthesia) and systemic disorders (chills, dizziness, headache and vomiting). these records make it possible to including tityus pusillus as a species of medical importance in brazil.
