Like most ecological communities, aspen (Populus tremuloides) forests are influenced by a synergy of bottom-up (resources-driven) and top-down (predator-driven) processes. Since the 1920s, ecologists have observed the decline of many aspen communities throughout the Intermountain West. The extent and possible drivers of this decline are topics of much recent scientific...
In recent years the “working landscape” concept has risen to prominence in popular, academic, and policy discourse surrounding conservation of both natural and cultural values in inhabited landscapes. Despite its implied reconciliation of commodity production and environmental protection, this concept remains contested terrain, masking tensions over land use practices and...
Quaking aspen (Populus tremuloides) sustainability is a topic of intense interest in forest ecology.
Reports range from declines to persisting or increasing coverage in some areas. Moreover, there is little
agreement on ultimate factors driving changes. Low aspen recruitment has been attributed to climate
patterns, past management, herbivore increases, competitive...
Small hydropower plants divert part of the water from wide and physically complex
stream channels with active hyporheic areas to narrow and hydraulically simple concrete canals,
and thus, might affect nutrient dynamics. We compared nutrient uptake in diversion canals and
in stream channels in the Leitzaran Stream (Basque Country, northern...
