A stable finite-difference scheme for growth and diffusion on a map [PDF]

arXiv, 2015
We describe a general Godunov type splitting for numerical simulations of the Fisher/Kolmogorov-Petrovski-Piskunov growth and diffusion equation in two spatial dimensions. In particular, the method is appropriate for modeling population growth and dispersal on a terrestrial map.

Assessing Groundwater Potential in the Ziway Lake Watershed Using Geographical Information System, Analytic Hierarchy Process, and Drinking Water Quality Index

Global Challenges, EarlyView.
This study identifies groundwater potential zones in Ethiopia’s Ziway Lake watershed using GIS and the SWAT model. Over half the area shows moderate to very high potential. Nearly 40% of high‐potential zones also have good to excellent water quality. The results offer a practical tool for sustainable groundwater management, with potential application ...

Biogeography of tenebrionid beetles (Coleoptera: Tenebrionidae) in the circum-Sicilian islands (Italy, Sicily): Multiple biogeographical patterns require multiple explanations

European Journal of Entomology, 2011
The tenebrionid beetles on 25 circum-Sicilian islands were studied to determine the influence of island geographical and landscape features on three main intercorrelated biogeographical patterns: (1) species richness, studied using species-area and ...

From Site Selection to Characterization: Assessment of Potential Reservoirs in the Lurestan Basin of Iran for Carbon Sequestration

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The increasing global focus on carbon sequestration underscores the need for comprehensive CO2 storage atlases, extending beyond Europe and America to other countries that are significant contributors to carbon dioxide emissions. This article addresses this imperative by examining the CO2 storage potential in the Lurestan area of Iran, with a ...

Changing nature of Pleistocene interglacials - is it recorded by paleosoils in Hungary (Central Europe)?

Hungarian Geographical Bulletin, 2015
Based on stable isotope analyses of worldwide reference curves, it has long been apparent that duration, intensity and climatic conditions of Pleistocene interglacial periods were significantly diverse.

On the importance of being structured: instantaneous coalescence rates and a re-evaluation of human evolution [PDF]

arXiv, 2015
Most species are structured and influenced by processes that either increased or reduced gene flow between populations. However, most population genetic inference methods ignore population structure and reconstruct a history characterized by population size changes under the assumption that species behave as panmictic units.
