Way in which individuals distribute themselves across landscape, including movement patterns and spatial organization like home range size and overlap

Variation in soil moisture conditions creating distinct dry and wet meadow habitat types

Geographic classification system used to reduce complexity and simplify presentation of continental-scale results

Characterization of how snow properties vary across spatial scales using correlation lengths and variogram analysis

Areas where organisms can persist during periods of unfavorable climate change

Areas of transition between adjacent, distinct ecosystems with unique species assemblages at the fringes of mature stands

The process by which rivers cut down into bedrock and lower their elevation over time

Pattern of fire occurrence including frequency, intensity, and timing that shapes ecosystem dynamics

Mountain ecosystem characterized by specific elevation, climate, and vegetation adapted to montane conditions

Geometric ground formations created by freeze-thaw processes in alpine environments

Study of ecological effects of roads and traffic on natural systems

Differences in environmental conditions and species composition between north and south-facing slopes

Human-made structures mimicking beaver dams implemented in restoration projects to slow flow, aggrade sediment, and reconnect streams to floodplains or create wetland conditions

Fragmented vegetation structure affecting bird population abundances and foraging opportunities

Rehabilitation of degraded streams using various techniques to restore natural ecosystem functions and prepare habitats for native species recolonization

Grazing practices designed to maintain ecological health while supporting livestock operations

Metric quantifying the topographic position of a site relative to surrounding landscape

The biogeographic transition zone between subalpine forest and alpine tundra, representing the elevational limit of individual trees with an upright growth form

Physical structure and arrangement of beaver ponds, specifically comparing single isolated ponds versus terraced series of connected ponds

Raster representation of terrain elevation used to derive topographic attributes like slope and aspect

Spatial sampling design measuring wildlife responses at increasing distances from disturbance sources

Linear scratches and grooves carved into bedrock by glacial ice movement

Mass displacement and sediment transport processes involving landslide material movement

The relative difficulty of movement through different types of non-habitat matrix surrounding habitat patches

Floodplain regions that follow the meandering pattern of rivers and serve as scaling motifs for ecosystem modeling

Moving native plants from one location to establish them in a disturbed site as a revegetation technique

The physical arrangement and composition of vegetation including coverage of different plant types, heights, and density

Last defensive line of German military occupation in the northern Emilia-Romagna Apennine Mountains built by forced Italian mountain inhabitants

A spatial pattern of rapid exhumation concentrated in a central zone with decreasing rates toward the periphery

Natural waterfall barriers that create transitions between fishless upstream reaches and fish-containing downstream reaches

Battle-zone landscapes that are always in motion and in a process of becoming, where civilian and military landscapes merge and multi-vocal overlapping accounts are produced
