Abstract The purpose of the present study is to investigate extreme values ice drift speed, which are also considered in light magnitude simultaneous wind speed. relationship between speed and studied. long-term data collected by using local subsurface measurements based on acoustic Doppler current profilers (ADCP) Beaufort Sea during period 2006–2017. Upward-looking sonars (ULS) deployed order...

The queen conch Eustrombus gigas is an important fisheries resource in the Caribbean region. In Cuba Island the studies about this resource are very scarce and particularly in the Southeastern regions of the country. With the aim to get important fishery information about this gastropod, adult Queen Conch density and frequency of reproductive activity were evaluated in Cabo Cruz, Cuba, during 2...

Many short-lived organisms pass through several generations during favorable growing seasons, separated by inhospitable periods during which only small hibernating or estivating refugia remain. This induces pronounced seasonal fluctuations in population size and metapopulation structure. The first generations in the growing season will be characterized by small, relatively isolated demes wherea...

Many temperate zone animals adapt to seasonal changes by altering their physiology. This is mediated in large part by endocrine signals that encode day length and regulate energy balance and metabolism. The objectives of this study were to determine if the daily patterns of two important hormones, melatonin and cortisol, varied with day length in captive brown bears (Ursus arctos) under anesthe...

Figs are a remarkable food resource to frugivores, mainly in periods of general fruit scarcity. Ficus calyptroceras Miq. (Moraceae) is the only fig species in a type of dry forest in western Brazil. In this study I examined the fruiting pattern as well as fig consumption by birds in F. calyptroceras. Although rainfall was highly seasonal, fruiting was aseasonal, since the monthly proportion of ...

Effects of environmental factors such as ewe age, season of exposure, and time from lambing to exposure on fertility were evaluated using records on 1,084 Dorset ewes in the STAR accelerated lambing system. The STAR program consisted of five 30-d concurrent breeding and lambing periods per year beginning on January 1, March 15, May 27, August 8, and October 20. Fertility in the flock changed in...

The site of Kul Tepe is located near the city of Hadishahr, in Eastern Azerbaijan Province. It is an ancient multi-period mound, having an extension of about 6 hectares and rising 19 meters above the surrounding land. The second season of archeological excavations at the site, carried out in 2013, aimed at clarifying its chronology and its settlement organization. In the meantime it aimed at el...

the impact of land use intensity on the abundance and diversity of arbuscular mycorrhizal fungi (amf) was investigated at six land use types viz., natural forest, grassland, acacia plantations, cardamom plantations, coffee plantations and paddy fields in the niligiri biosphere of the western ghats in south india. there was no significant difference in amf root colonization in different land use...

Sewage introduction into rivers has altered the physical and chemical properties of waters also microbial metabolism. This study aimed to evaluate Escherichia coli nutrient concentrations in Maratuã Crumaú (Santos Estuary, Brazil) during two periods with distinct magnitudes freshwater runoff, verifying possible relation abiotic changes Water sampling was performed October/2012 (dry season) Janu...

Influenza and respiratory syncytial virus (RSV) infections are responsible for considerable morbidity, mortality and health-care resource use. For the Netherlands, we estimated age and risk-group specific numbers of antibiotics, otologicals and cardiovascular prescriptions per 10,000 person-years during periods with elevated activity of influenza or RSV, and compared these with peri-season rate...
