In the past 30 years, the notion of landscape has emerged in ecology as a result of both theoretical strategies and practical aspects of land use. This has generated a variety of computerized models addressing both objectives and techniques. Scientists model landscapes for at least two reasons: to better understand the landscape dynamics themselves (called intrinsic needs) and to offer a realis...

Insect community ecology has traditionally encompassed measures of taxonomic diversity (e.g., alpha, beta) and their biogeographical correlates such as latitude and connectivity [1,2]. Or, research has focused on quantifying food webs based on taxonomic diversity, resource breadth and trophic interactions [3,4]. For this section on community ecology we solicited contributions from researchers w...

In the second half of the last century, remote sensing methods became increasingly influent in the civil sector of the economy. Their various applications such as monitoring and analysis of the atmosphere, terrestrial and aquatic features of the environment, made them widely applicable in numerous scientific and economic fields. The purpose of present work is to describe the past, current statu...

Ecology Montane Meadows in the Sierra Nevada: A comparison of terrestrial and aquatic assessment methods Abstract We surveyed montane meadows in the northern Sierra Nevada and southern Cascades for two field seasons to compare commonly used aquatic and terrestrial-based assessments of meadow condition. We surveyed 1) fish, 2) reptiles, 3) amphibians, 4) aquatic macroinvertebrates, 5) stream geo...
