Experimental replication of watersheds of substantial size is impractical; it is impossible to achieve uniformity of topographic, edaphic, and physiographic conditions in such watersheds. Some other approach to the development of experimental error is needed if it is necessary to apply parametric statistical tests in this situation. We tackled this question with a study design that used time, r...

Mountain caribou, an ecotype of woodland caribou (Rangifer tarandus caribou), are a species at risk and so are a primary focus in forest management in the Columbia Mountains Forest District. Two multivariate habitat models have been developed based on telemetry data to predict caribou habitat by associating forest cover and physiographic variables at various spatial scales and seasons: one usin...

A nation's economic geography can have an enormous impact on its development. In Thailand, we show that a high concentration of enterprise in an area predicts high subsequent growth in and around that area. We also find spatially contiguous convergence of enterprise with stagnant areas left behind. Exogenous physiographic conditions are correlated with enterprise location and growth. We fit a s...

Ecological niche modeling of the main forest-forming species within same geographic range contributes significantly to understanding coexistence and regularities formation their current spatial distribution. The abiotic biotic environmental variables, as well dispersal capability, affecting distribution in Caucasus, have not been sufficiently studied. We conducted studies physiographic boundari...

Through recognition and mastery of the regional differences influencing factors China’s rural housing rental rates, we can better understand changes in functional attributes homesteads deepen reform “separating land ownership rights, contract management rights” homesteads. Accordingly, this paper uses village residence data from China Labor-force Dynamics Survey to measure degree rates at provi...

We used boosted regression trees (BRT) to model stream biological condition as measured by benthic macroinvertebrate taxonomic completeness, the ratio of observed to expected (O/E) taxa. Models were developed with and without exclusion of rare taxa at a site. BRT models are robust, requiring few assumptions compared with traditional modeling techniques such as multiple linear regression. The BR...

Risk management is a significant part of federal wildland fire in the USA because policy encourages use to maintain and restore ecosystems while protecting life property. In this study, patterns wildfire risk were explored from operational relative assessments (RRA) completed by land managers on 5087 wildfires 2010 2017 every geographic area USA. The RRA formal assessment used develop strategie...

Accurately determining the maximum designed water discharges of dams is extremely important, considering economic costs carrying out these types hydrotechnical works and possible disastrous consequences resulting from their incorrect design. This article describes applies probability distributions used in hydrology, with some recommended by Romanian legislation standard NP 129-2011. The methods...

This study documents the global distribution and characteristics of diurnally varying low-level jets (LLJs), including their horizontal, vertical, and temporal structure, with a special emphasis on highlighting the underlying commonalities and unique qualities of the various nocturnal jets. Two tools are developed to accomplish this goal. The first is a 21-yr global reanalysis performed with th...
