The relationship between water and renewable energy, as a vertebrate axis of the territory landscape its social acceptance in Monachil river valley, was analysed. Qualitative interviews surveys were designed implemented using quantitative techniques that enabled measure factors dimensions perception water, territory, landscape. main values elements inventory, their links with ecosystem services...

Introduction In the lowlands of the upper Willamette River Valley, Oregon, winter flooding is an annual phenomenon driven by the seasonal precipitation regime of the Pacific Northwest (Hamlet and Lettenmaier 1999). Predictable inundation of river floodplains and expansion of stream networks like these are major processes influencing entire aquatic communities (which include fish, frogs, salaman...

As extreme surface processes, long-term river damming and outburst events can impact sediment supply transportation in valleys therefore significantly change the landscape. Lacustrine sediments were identified wide Xigaze Valley, middle reaches of Yarlung Tsangpo River Tibet, an area which has been considered to have a paleodammed lake. However, evolutionary process mechanisms associated with t...

And let some mountains collapse headlong into the depths of a valley and dam up the swollen waters of its river But soon breached, the river bursts the dam and gushes out in high waves. Let the biggest of these strike and demolish the cities and country residences of that valley. And let the disintegration of the high buildings of the said cities raise much dust which will rise up like smoke or...

We examined the distribution of ground-flora species (herbaceous and woody species <1 m tall) across riparian areas of northeastern Wisconsin in an effort to understand how hierarchical landscape properties, such as the physiographic system (ground moraine and outwash plain), valley system (constrained and unconstrained), and valley floor landforms influence distribution patterns of ground-flor...

The natural disturbances paradigm in forestry management emphasizes understanding and emulating natural variation in forest ecosystems processes and patterns. Using dendrochronological data in two study areas in the Stein River valley, British Columbia, we provide empirical models of the spatial-temporal variation in boundaries of low-severity fires. With geographic information systems, databas...

Ground based in-situ measurements of carbon dioxide (CO2) and methane (CH4) at the dry lakebed at Railroad Valley (RRV) playa, Nevada, USA (38°30.234′ N, 115°41.604′ W, elevation 1437 m) were conducted over a five day period from 20–25 June 2010. The playa is a flat, desert site with virtually no vegetation, an overall size of 15 km × 15 km and is approximately 110 km south-west of the nearest ...

In recent years, comparative genome sequence analysis of African Mycobacterium ulcerans strains isolated from Buruli ulcer (BU) lesion specimen has revealed a very limited genetic diversity of closely related isolates and a striking association between genotype and geographical origin of the patients. Here, we compared whole genome sequences of five M. ulcerans strains isolated in 2004 or 2013 ...
