The Relationship

Well adapted animals are characterized by maintain homeostasis under natural conditions. The present study aimed to evaluate physiological and morphological responses, as well as identify the relationship between these parameters in order to maintain homoeothermic status, in the dry and rainy season. Measurements were taken from 383 Morada Nova hair ewes, under dry and rainy season. The studied variables included rectal temperature (RT), respiratory rate (RR), coat thickness (CT), hair length (HL), hair diameter (HD) and hair density (D). Blood samples were collected for determining biochemical, erythrogam and hormone concentration. The evaluated blood parameters from the Morada Nova breed did not demonstrate any variation from the reference interval established for sheep, confirming its adaptability profile even under high radiation and air temperatures. Multivariate analyses were performed in order to determine relationship between morphological, biochemical, erythrocyte and hormonal traits in each season. Differences correlations were observed according to season of the year. In the dry season, the correlations were significant among RT, RR, Packed cell volume (PCV), thyroxine (T4), Glucose (GLU), CT, HL, Globulin (GLO) and Total Protein (TP), whereas in dry season the characteristics that showed greater correlation were Mean corpuscular volume (MCV), thyroid hormones, Creatinine, GLO, TP, PCV and GLU. In conclusion, Morada Nova ewes was able to maintain homeothermy, even in the most stressful environmental conditions. Their hematological, biochemical and hormonal profile were within the normal range for sheep, confirming the adaptability of this local breed to the Brazilian semiarid environment.

Introduction. The drought in the Brazilian semiarid region has affected the quality of water. This study assessed the relationships between enteric parasitoses, water management, and water quality, correlating them with pluviometric seasonality.Methods. Cross-sectional surveys were carried out in four rural communities at the beginning of the dry season (n=151), at the end of the dry season (n=184), and in the rainy season (n=199), in order to collect sociodemographic data, human fecal samples, and samples of the water used for human consumption for physicochemical and microbiological analyses. In 2015, water filters were provided to 30 households under study.Results. There was an increasing trend in detection rates of commensal protozoa and theEntamoeba histolytica/Entamoeba disparcomplex at the beginning of the rainy season, with detection rates of 6% in 2014 and 21.6% in 2016.Giardia intestinalisandAscaris lumbricoidespresented distinct temporal distributions, which peaked in 2015: 20.1% and 30%, respectively. The proportion of inhabitants drinking inadequate water was 55% at the beginning of the dry season and 28.8% at the end of the dry season, reaching 70.9% at the beginning of the rainy season. The presence of filters reduced this proportion among those who received the hollow ceramic candle filter.Conclusions. Data suggest that the strategies to increase water supply in the Brazilian semiarid region can be ameliorated in order to improve the quality of drinking water.

The last-stage larva of Bromeliagrion rehni Garrison in De Marmels & Garrison, 2005 is described and illustrated and bionomics and habitat information on this species are provided. The study was conducted in the Reserva Florestal Adolpho Ducke, located near Manaus, state of Amazonas, Brazil.Twelve samplings were done between April, 2003 and April, 2005: six in the rainy season and six in the dry season. In each sampling month, 12 bromeliads (Guzmania brasiliensis Ule, 1907, Bromeliaceae) were collected, six of which were terrestrial and six epiphytic, yielding144 samples. A total of 75 specimens of B. rehni were collected. The relationship between larval B. rehni abundance and the measured environmental parameters (volume (ml), pH, season and stratum) was significant (ANCOVA, F = 5.296, d.f. = 130, p < 0.001). Larvae were most abundant in the rainy season (p < 0.01) and water volume was positively related to the abundance of B. rehni. Larvae of B. rehni can be distinguished from those of B. fernandezianum (the only species in the genus with described larvae) by the number of setae in the prementum and by the color of the apical region of the femur. The association of this species with phytotelmata of G. brasiliensis is reported here for the first time.

The study was conducted in a facility for pigs during the nursery and finishing in the town of 'Montadas', in the semiarid of the state of Paraiba, Brazil, in the rainy and dry season, aiming to evaluate the concentration of oxygen, methane, carbon monoxide and ammonia, and the bioclimatic indexes: ambient temperature (AT), relative humidity (RH) and the index of black globe temperature and humidity (IBGTH). These indexes differed significantly (P>0.05) between the periods and times. The AT in the rainy season was in the thermal comfort zone(TCZ) in most of the times in the nursery; for the finishing phase, thermal discomfort occurred; during the dry season, there was thermal comfort in the nursery phase; in the finishing phase the thermal discomfort occurred at all times. In the rainy season, the IBGTH was in TCZ; in the dry season, it was above the TCZ. The RH in the rainy period was in the TCZ; in the dry season, in most of the times, below the range of the TCZ. The concentration of gases showed no differences (P > 0.05) between periods and between the times, and the carbon monoxide, hydrogen sulfide and methane were below 1.0 ppm, and the ammonia showed a mean of 5.2 ppm. None of the analyzed gases exceeded the limits established by Brazilian and international standards for animals and workers.

Study Results

Passive thermal comfort has been widely used to test the thermal performance of a building. The science of active thermal comfort is important to be connected with the science of architecture. The currently developing active thermal comfort is adaptive thermal comfort. Vernacular houses are believed to be able to create thermal comfort for the inhabitants. The present study seeks to analyze the connection between the architectural elements of vernacular houses and adaptive thermal comfort. A mixed method was applied. A quantitative approach was used in the measurement of variables of climate, while a qualitative methodology was employed in an interview on thermal sensations. The connection between architectural elements and adaptive thermal comfort was analyzed by considering the correlation among architectural features, the analysis results of thermal comfort, and the Olgyay and psychrometric diagrams. At the beginning of the rainy season, residents of exposed stone houses had the highest comfortable percentage of 31%. In the middle of the rainy season, the highest percentage of comfort was obtained by residents of exposed brick and wooden houses on the beach at 39%. The lowest comfortable percentage experienced by residents of exposed stone houses at the beginning of the dry season was 0%. The beginning of the dry season in mountainous areas has air temperatures that are too low, making residents uncomfortable. The study results demonstrate that adaptive thermal comfort is related to using a room for adaptation to create thermal comfort for the inhabitants.

In light of the unfavorable climatic conditions for keeping Africanized bees in apiaries in the Brazilian semiarid, especially during the dry season, this study aimed to assess how the internal water supply in beehives influences the development of Africanized bee during this period in the semiarid region of Piaui state (PI), Brazil. The experiment was conducted in September and October 2016, in the Experimental Apiary of the Study Group on Bees of the Piaui Semiarid, located in Picos (PI). The hives were standardized in terms of population size and amount of food. To that end, a data sheet was filled out and the brood area measured (cm²) at the beginning and end of the experiment. Graduated 500 mL Boardman entrance feeders filled with potable water were installed to measure daily water consumption during the experiment. There was a significant variation in water use by the bees, with average daily consumption of 74.6 mL ± 25.5. With respect to colony development, there was an increase in the number of frames and brood area. Internal water supply can be recommended as a suitable management technique for bee colonies during the dry season in the semiarid.

Indonesia geographical location (60LU-110LS) causes most of its region experience heavy amount of rainfall. Overflowing rain water is consequently ample in amount, and potentially a great source for irrigation. Both urban and subburbs part of Medan, where some primary livelihood is in agriculture, benefit from this natural event. However the level of availability all year is not certain. Too much in rainy season means flood, and too little means drought in dry season. Farmers normally neglected the importance of storing rain water in rainy season in order to supply the dry season, and thus becomes problem for farmers. How much water can potentially be used for agriculture in urban area, what is the relationship between water amount with soil texture, types of certain-soil-suitable crop, plant growth period. This research aims to analyze and answer this particular question.

This study aimed to evaluate the sexual behavior of 'Morada Nova' breeding sheep reared in the Brazilian semi-arid during dry and rainy seasons in a semi-intensive system. The behavioral data were gathered from 4 rams and 114 ewes, among which 55 during the rainy season and the other 59 females in the dry season. The behavioral observations were conducted from 6 am to 5 pm, during both periods. The observations were carried out continuously and split into 'event' (execution frequency) and 'state' (execution time). During the rainy season, the breeding sheep showed the most efficient sexual behavior, with a shorter reaction time (RT) and less frequent mount attempts (MA), being of 122 sec and 2.97, respectively. However, throughout the dry period, some sexual behaviors such as sniffing the urogenital of females (SUF), penis exposure (EXP), head tossing (HT), and courting of females (FC) became more frequent, mainly in the afternoon, as with the flehmen response (FR). Male courting behavior was more evident in the rainy season during the end of the day, remaining less active during the dry period. Sexual behavior intensity in 'Morada Nova' sheep varies throughout the day, especially in the dry season.
