Given the existence of plenty of river valleys connecting Southeast and East Asia, it is possible that some inland route(s) might have been adopted by the initial settlers to migrate into the interior of East Asia. Here we analyzed mitochondrial DNA (mtDNA) HVS variants of 845 newly collected individuals from 14 Myanmar populations and 5,907 published individuals from 115 populations from Myanm...
The Warner Pass map area is located 185 kilometres north of Vancouver on the northeastern margin of the Coast Mountains. It covers an area of 980 square kilometres within the Chilcotin Range, and is characterized by rugged mountains and glaciated U-shaped valleys; elevations vary from IS00 metres to over 3000 mctres, with a treeline at about 1800 metres. The sheet was mapped at a scale of 1:20 ...
This work deals with taxonomy, geographical distribution as well as known ecology of oribatid mites of the genus Conchogneta Grandjean, 1963 in the world. The majority of species belonging to this genus is known to be widely distributed in Europe, but only three of them are found in other areas of the northern hemisphere. Most species of Conchogneta are inhabitants of litter of various types of...
Altogether 327 valleys and their 314 cross-sectional profiles were analyzed on Mars, including width, depth, length, eroded volume, drainage and spatial density, as well as the network structure. According to this systematic analysis, five possible drainage network types were identified such as (a) small valleys, (b) integrated small valleys, (c) individual, medium-sized valleys, (d) unconfined...
Sensor networking has emerged as a key research challenge on the road to fully pervasive distributed systems. Much current work on sensor networking, however, focuses on sensor networks in relative isolation, and de-emphasises their integration into the wider networked environment. We are focusing on such integration in the context of so-called ‘pervasive grids’ in which sensor networks are int...
Improved Methods for Obtaining Permeability Maps of Aquifers for the Hydrogeological Model of Latvia
In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by the scientists of Riga Technical University (RTU). LAMO comprises geological and hydrogeological data provided by the Latvian Environment, Geology and Meteorology Centre (LEGMC) for the active groundwater zone of Latvia. In 2013–2015, LAMO was notably upgraded. The number of HM layers and the density of hydrographica...
Histoplasma capsulatum is a dimorphic fungus known to be endemic to the Mississippi and Ohio River valleys of North America. Infection is the result of exposure to the microconidia of the mold phase of the organism, and the degree of exposure and immunocompetency of the host are thought to be important determinants in the severity of consequent illness [1]. In most patients, histoplasmosis mani...
Anthropogenic global climate changes are one of the greatest threats to biodiversity. Distribution modeling can predict the effects of climate changes and potentially their effects on genetic diversity. DNA barcoding quickly identifies patterns of genetic diversity. As a case study, we use DNA barcodes and distribution models to predict threats under climate changes in the frog Nanorana parkeri...
INTRODUCTION Blastomyces dermatitidis. The most heavily endemic areas in the world are in the United States. These include the Mississippi and Ohio River Valleys and around the Great Lakes and extends to northern Wisconsin and northern Minnesota. Fungal growth occurs in nitrogen-rich soil close to streams, rivers and lakes, and aerosolization is facilitated by rain, excavation or other disturba...
0 aks (Querczrs spp.) are among the most ecologically and economically valued trees of the floodplain forests which occupy the river valleys that dissect the Gulf and Atlantic coastal plains of the southeastem United States. In these floodplain forests, several species from the sections Quercus and Lobarae are commonly found distributed along a gradient of sites ranging from hydric to mesic. Bo...
