(Hindawi Limited, 2019-02-11)The current study aimed at investigating cycles and the spatial autocorrelation pattern of anomalies of thunderstorms in Iran during different periods from 1961 to 2010. In this analysis, 50-year periods (1961–2010) of thunderstorm codes have been ... -
(Hindawi Limited, 2019-02-18)Objectives. Obesity-related physiological changes can limit improvements of obese subjects after training. The aim was to investigate obesity, muscular strength, and physical function in community-dwelling nonsarcopenic old adults. Methods. Nonsarcopenic ...

(American Association for the Advancement of Science (AAAS), 2019-03-20)Introgressive hybridization creates networks of genetic relationships across species. Among marine fish of the Gadidae family, Pacific cod and walleye pollock are separate invasions of an Atlantic cod ancestor into the Pacific. Cods are ecological ...

Mapping of Signaling Pathways Linked to sIgAD Reveals Impaired IL-21 Driven STAT3 B-Cell Activation (Frontiers Media SA, 2019-03-18)Objectives: It has recently been shown that individuals with selective IgA deficiency (sIgAD) have defective B cell responses both to T cell dependent and independent mimicking stimulations. The complex intracellular signaling pathways from different ...

(Springer Science and Business Media LLC, 2019-04-03)Objective: A recurrent observation is that associations between self-reported and objective medication adherence measures are often weak to moderate. Our aim was therefore to identify patients with different profiles on self-reported and objective ...

(Informa UK Limited, 2019-04-16)We propose a new exchange rate model using interest rate differential (IRD) time series as the input, and we fit the new model with empirical data for calibration. We assume that exchange rate modeling cannot be based on the response to a single shock ...

(Inter-Research Science Center, 2019-02-07)Entanglement in fishing gear is a significant anthropogenic source of large whale injury and mortality. Although entanglements have been reported in the eastern North Atlantic, their frequency has not been previously estimated. This study used systematic ...

(Frontiers Media SA, 2019-04-04)Non-breeding movement strategies of migratory birds may be expected to be flexibly adjusted to the distribution and quality of habitat, but few studies compare movement strategies among populations using distinct migration routes and wintering areas. ...

(University of Iceland, School of Social Sciences, Faculty of Business Administration, 2020-10)Flestir fiskistofnar heims eru nýttir að fullu eða ofveiddir. Ofnýting hefur í för með sér slæmar vistfræðilegar, hagrænar og félagslegar afleiðingar. Minna er hægt að veiða úr ofveiddum stofnum og hætta getur verið á hruni þeirra. Og af því að þeir ...

(Canadian Science Publishing, 2019-08)The biological status of many commercially exploited fishes remains unknown, mostly due to a lack of data necessary for their assessment. Investigating the spatiotemporal dynamics of such species can lead to new insights into population processes and ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)Crangonyx islandicus is a groundwater amphipod endemic to Iceland. Genetic analysis suggests that the species has been diverging in Iceland for at least 4.8 Myrs indicating it has survived in a subglacial refugia as Iceland was repeatedly covered by ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)Freshwater springs are thermally stable environments which are largely unaffected by changes in air temperature. They could thus have the potential to buffer rising temperatures and serve as small-scale refugia for aquatic invertebrates in a warming ...
