Climate change is affecting agriculture doubly: evapotranspiration is increasing due to increments in temperature while the availability of water resources is decreasing. Furthermore, irrigated areas are expanding worldwide. In this study, the dynamics of climate change impacts on the water cycle of a newly irrigated watershed are studied through the calculation of soil water balances. The stud...

Global warming has created opportunities and challenges for the survival and development of species. Determining how climate change may impact multiple ecosystem levels and lead to various species adaptations is necessary for both biodiversity conservation and sustainable biological resource utilization. In this study, we employed Maxent to predict changes in the habitat range and altitude of P...

BACKGROUND Risk factors for mitral annular calcification (MAC) and cardiovascular disease (CVD) demonstrate significant overlap in the general population. The aim of this paper is to determine whether there are independent relationships between MAC and demographics, traditional and novel CVD risk factors using cardiac CT in the Chronic Renal Insufficiency Cohort (CRIC) in a cross-sectional stud...

Global climate model outputs involve uncertainties in prediction, which could be reduced by identifying agreements between the output results of different models, covering all assumptions included in each. Fusarium oxysporum f.sp. is an invasive pathogen that poses risk to date palm cultivation, among other crops. Therefore, in this study, the future distribution of invasive Fusarium oxysporum ...

Global primary energy consumption has increased tenfold over the course of 20th Century, availability non-renewable is becoming scarce, and burning fossil fuels leading to global warming. Climate change now become tangible. The will act against apparent in western world, Germany particular. This poses a particular challenge for chemical pharmaceutical industry, since, future, not only input, bu...

The aims of this study are to model past (LIG, LGM and Mid-Holocene), present future (2050 2070) distributions the Quercus vulcanica Boiss. & Heldr. ex Kotschy by using Maximum Entropy, predict suitable areas for conservation species planning. MaxEnt dis¬tribution modeling was used distributions. Results bioclimatic conditions show that distribution area expanded then contracted (LIG HOL). ...

The Queen of the Andes (Puya raimondii) is considered an ‘endangered’ species due to habitat fragmentation and loss, declining populations throughout its range. We used ecological niche modeling in context multiple climate change scenarios estimate potential present future (2050 2070) distribution species, analyzing effects loss importance natural protected areas across Our models predicted a r...
