Dinâmica populacional da mosca-dos-chifres (Haematobia irritans) em bovinos da raça Guzerá e mestiço em Selvíria, MS

Aiming to know the population dynamics of horn fly on cattle in the municipality of Selviria, MS, Brazil, a study was conducted from March 2004 to June 2005 in the Education, Research and Extension Farm, from Unesp - Campus de Ilha Solteira, located in the municipality of Selviria, MS. It was used IS cows of the Guzera breed and 15 crossbred (Guzera X Holstein-Friesian), respectively 3 and 4 years old, naturally infested. During the experimental period these animals did not receive any insecticide treatment. Visual fly counting by on back region of the animals was carried out at 14 day interval. The horn fly showed two peaks of infestation during the year, one in April and another in October. In the months of highest infestation, the average number of flies did not exceed a 104. The months in which was significant difference between crossbred and Guzera breed was in April, May, August and September 2004 and February, March and April 2005, always with crossbred with higher infestation. In the region studied Haematobia irritans was present throughout the year.

Population dynamics and net primary production of the aquatic macrophite Nymphaea rudgeana C. F. Mey in a lotic environment of the Itanhaém River basin (SP, Brazil)

Neste trabalho, foi estudada a dinâmica populacional e estimada a produção primária líquida da macrófita aquática Nymphaea rudgeana em um braço do rio Itanhaém (Estado de São Paulo, Brasil). Esta espécie apresenta uma ampla variação anual de biomassa, em função da estação do ano, no local estudado. A partir do mês de novembro (13,1 g PS/m²), pode ser observado um aumento gradual da biomassa, atingindo o máximo em fevereiro (163,1 g PS/m²). Posteriormente, a biomassa diminui, mantendo-se em níveis baixos até um novo período de crescimento. A diminuição de biomassa está associada ao desenvolvimento de macrófitas flutuantes (Pistia stratiotes e Salvinia molesta) e, subseqüentemente, às condições ambientais desfavoráveis (valores de salinidade elevados) ao seu desenvolvimento. A produção primária líquida de N. rudgeana foi obtida a partir dos dados de biomassa e seu valor é estimado entre 3,02 e 3,82 t/ha/ano.

Acute effects of flexible pole exercise on heart rate dynamics

Introduction: Exercise with flexible poles provides fast eccentric and concentric muscle contractions. Although the literature reports significant muscle chain activity during this exercise, it is not clear if a single bout of exercise induces cardiac changes. In this study we assessed the acute effects of flexible pole exercise on cardiac autonomic regulation.Methods: The study was performed on 22 women between 18 and 26 years old. We assessed heart rate variability (HRV) in the time (SDNN, RMSSD and pNN50) and frequency (HF, LF and LF/HF ratio) domains and geometric indices of HRV (RRTri, TINN, SD1, SD2 and SD1/SD2 ratio). The subjects remained at rest for 10 min and then performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 60 min and HRV was analyzed.Results: We observed no significant changes in time domain (SDNN: p=0.72; RMSSD: p=0.94 and pNN50: p=0.92) or frequency domain indices (LF [nu]: p=0.98; LF [ms(2)]: p=0.72; HF [nu]: p=0.98; HF [ms(2)]: p=0.82 and LF/HF ratio: p=0.7) or in geometric indices (RRTri: p=0.54; TINN: p=0.77; SD1 p=0.94; SD2: p=0.67 and SD/SD2: p=0.42) before and after a single bout of flexible pole exercise.Conclusion: A single bout of flexible pole exercise did not induce significant changes in cardiac autonomic regulation in healthy women.

Ecologia alimentar de Tatu-Peba, Euphractus sexcinctus (Linnaeus, 1758), na Fazenda Nhumirim, Pantanal da Nhecolância, MS

Studies on feeding ecology are important tools for the understanding of feeding strategies and niche dynamics. Information on the type of food consumed, how, and where it is acquired, enable the elucidation of species behavioral, evolutionary and ecological aspects. The diet study based on fecal material enables a low-cost, informative research and avoids the sacrifice of animals. The general aim of this study is to characterize the diet of Euphractus sexcinctus, the yellow-armadillo, based on fecal samples, to contribute with additional information on their feeding habits. The study was undertaken at the Nhumirim ranch, Pantanal da Nhecolândia, MS, during the months of February and March, 2014. The fecal material was collected during the manual capture of the animals and oven dried at 60°C. The food items found in the feces were sorted using a magnifying glass and separated in the following categories: plant matter, invertebrates and soil. Invertebrates were identified to the order level and the plant matter to the lowest taxonomic level possible. Aiming to evaluate the invertebrate availability in the soil, pitfall traps were installed next to the location where individuals were captured, during the months of April and May. We were able to estimate the frequency with which item was consumed during the studied period, and if there is a relationship between the frequency of consumed invertebrates and their availability environment. Among the analyzed samples, we could observe the frequency of occurrence (FO) of plant matter, invertebrates and soil in all the samples. The main invertebrate orders found in the samples were: Coleoptera, Orthoptera and Hymenoptera, with FO of 100%, 100% and 87,5%, respectively. Seeds were found in 100% of the samples. The FO of the Byrsonima orbignyana was high (62,5%), and evidences the potential of the yellow-armadillos as seed dispersers. The use of other techniques, such as the micro-histological...
