Содержание фикобилипротеинов в некоторых видах красных водорослей Черного моря
Provedor de dados: 13
Autores: Поспелова, Н. В.; Нехорошев, М. В.
Исследовано содержание фикобилипротеинов – R-фикоэритрина и аллофикоцианина в некоторых видах наиболее распространенных в Черном море красных водорослей. В клетках водорослей количество R-фикоэритрина превышает количество аллофикоцианина. Показано, что содержание пигментов различно для разных видов багрянок и зависит от сезона года.

Seasonal Variations in the Histometric Characteristics of the Reproductive Organs of Pubertal West African Dwarf Bucks in their Native Tropical Environment
Provedor de dados: 77
Autores: Bitto,I.I; Egbunike,G. N; Akusu,M. O.
As ambient temperature and humidity are high all year round within clearly defined dry and rainy seasons in our humid tropical environment, we evaluated the effects of season on the histometric characteristics of the reproductive organs of pubertal West African dwarf bucks using 8 healthy animals. There were no significant differences (p&gt;0.05) between the rainy and dry seasons in the basement membrane of the testes, seminiferous tubular diameter, and round spermatid nuclear diameter. There were also similarities (p&gt;0.05) between the seasons in epididymal luminal diameters, epididymal epithelial heights as well as in Leydig/sertoli cell ratio and sertoli cell Índex. Quadratic regression analyses showed that all the histometric characteristics of the...

Variabilidad estacional del plancton en la Bahía de Manta en la costa ecuatoriana, durante el 2011
Provedor de dados: 20
Autores: Naranjo, Ch.; Tapia, M.E.
In 2011, in the Bay of Manta was presented a high diversity of phytoplankton species, determining a total of 75 species, 29 groups for the zooplankton, which were identified to species level the Phylum Chaetognatha identified 6 species and Cladocera with 2 species. The seasonal time during 2011, did not influence the average abundances of the dominant species of phytoplankton and zooplankton, using the student T Test statistic with 95% confidence However specific tests were performed between different stations have a greater diversity of species and stations with less diversity, showing a significant difference in the mean of the population of phytoplankton. The oceanographic conditions recorded in the Equatorial Pacific states mainly cooling during...

Estudio de los poliquetos (Gusanos marinos) en la zona intermareal y submareal de la Bahía de Manta (Ecuador), y su relación con algunos factores ambientales, durante marzo y agosto del 2011
Provedor de dados: 20
Autores: Villamar, F.
As a result of taxonomic analysis and the abundance of benthic polychaetes abtained from the subtidal area in five profiles with 15 stations at depths between 3 and 23 m. in Manta Bay, eight species were identified in march, the most abundant one being Cossura brunnea of the Cossuridae family. Eight species were identified in august, represented by the most abundant species, Paraonis gracilis from the Paraonidae family. For the  intertidal zone, five profiles in five different areas were analyzed, using techniques recommended by Roger J. Lincoln &amp; Gordon Sheals (1979). Two species were identified in march and four in august, with the most frquent and abundant species being Anaitides madeirensis of the Phyllodocidae family in both seasons of the year....

Penman-Monteith with missing data and Hargreaves-Samani for ETo estimation in Espírito Santo state, Brazil
Provedor de dados: 91
Autores: Venancio,Luan P.; Cunha,Fernando F. da; Mantovani,Everardo C.; Sediyama,Gilberto C.; Eugenio,Fernando C.; Aleman,Catariny C.
ABSTRACT The Penman-Monteith method (PM-FAO) is recommended as standard for calculation of reference evapotranspiration (ETo). However, its use requires a series of meteorological variables that is not normally available, restricting its application in many locations. A solution to the problem of unavailability of meteorological data was presented in FAO Bulletin 56, which contains methodologies for estimating wind speed, solar radiation and relative humidity. The objective of the present study was to evaluate the performance of the PM-FAO methodologies for missing data and Hargreaves-Samani as alternatives to the PM-FAO standard method at different time scales and seasons for the municipalities of Linhares and São Mateus, located in the northern region of...

Microclimate and thermal comfort indices in silvopastoral systems under different planting directions and seasons
Provedor de dados: 91
Autores: Carvalho,Rafael P. de; Heid,Debora M.; Davide,Livia M. C.; Piletti,Ligia M. M. da S.; Jesus,Fernanda L. F. de; Viegas Neto,Antonio L.
ABSTRACT The orientation of tree-rows in a silvopastoral system associated with different seasons of the year allows more or less sunlight penetration, resulting in deliberate modification of the microclimate composition and thermal conditions provided to animals. In this sense, the aims of this study were to evaluate microclimatic variables and thermal comfort indices for east-west and north-south oriented silvopastoral systems, compared to unshaded systems during summer and winter. The study was conducted at the Modelo II Farm (21° 08’ S 53° 17’ W) at an altitude of 354 m. A randomized block design in scheme of split-split plots with five repetitions was adopted. Two planting directions and a control treatment (unshaded) were evaluated in the plots....

ABSTRACT: Bees generally use different botanical sources of resins for the production of propolis. The elucidation of botanical sources of propolis and identification of the effects of seasonality on the chemical profile of propolis are recognized as two important aspects in the development of a high quality product. Thus, our objective was to elucidate the botanical source and identify the effect of the seasons on the chemical profile of propolis produced in southern Brazil. The chemical profile of the samples was analysed by spectrophotometric and chromatographic techniques and the results were coupled to multivariate analysis. Field observation of the foraging behaviour of Apis mellifera L. revealed its preference for the Baccharis dracunculifolia DC....

This study evaluated the microclimate in a system without shade (WS) and in a silvopastoral system (SP) with eucalyptus during summer and winter, by measuring the air temperature (Ta), black globe temperature (Tg), relative humidity (RH), wind speed (Ws), every 2 hours for 24 hours between rows, shade (SP) and no shade effect (WS). It was employed the randomized blocks design (months), in the plots (systems), subplots (hours) and sub-subplots (seasons). Except for Ta and RH, the Tg (24.73, 26.41ºC), Ws (3.16, 4.57 m s-1), Black globe-humidity index (BGHI) (71.83, 73.84), Thermal load index (TLI) (74.53, 76.11) and Radiant thermal load (RTL) (526.46, 595.80 W m-2), respectively for SP and WS, were higher in WS. Ta, RH and Ws had a quadratic effect of hour....

The role of phytophysiognomies and seasonality on the structure of ground-dwelling anuran (Amphibia) in the Pampa biome, southern Brazil
Provedor de dados: 42
Autores: MARAGNO,FRANCIÉLE P.; SANTOS,TIAGO G.; CECHIN,SONIA Z.
ABSTRACTConsidering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure. Additionally, we searched for species which can be indicators of habitat and seasons. The study was conducted in the Pampa biome, southern Brazil. Sampling was done through pitfall traps placed in three phytophysiognomies: grassland, ecotone grassland/forest; and forest. The seasonality factor was created by grouping months in warn and cold seasons. Sixteen species were found and the assemblages were influenced both by phytophysiognomies and climatic seasonality. In a paired comparison, the three phytophysiognomies...
