Ecography, EarlyView.Conservation has shifted towards a climate change adaptation approach in which expected species range shifts are increasingly considered to mitigate effects of climate change and habitat fragmentation on biodiversity. As part of this, ecological connectivity needs to be ensured to support gene flow and viable populations in the face of changing ...

Understanding ecosystem structure and function requires familiarity with the techniques, knowledge and concepts of the three disciplines of plant physiology, remote sensing and modelling. This is the first textbook to provide the fundamentals of these three domains in a single volume. It then applies cross-disciplinary insights to multiple case studies

In a broad sense, all rivers develop from rills and gullies in the process of erosion. Erosion is classified according to agents causing erosion into water erosion, wind erosion, gravity erosion, glacier erosion and cultural erosion. Water erosion occurs in different forms: splash erosion, sheet erosion, rill erosion, gully erosion and channel erosion.

The contribution of brown vegetation to vegetation dynamics
Ecology, 2010Indices of vegetation dynamics that include both green vegetation (GV) and non‐photosynthetic vegetation (NPV), that is, brown vegetation, were applied to MODIS surface reflectance data from 2000 to 2006 for the southwestern United States. These indices reveal that the cover of NPV, a measure of vegetation brownness and a component of ecosystems ...

Long-Term Studies of Vegetation Dynamics
Science, 2001By integrating a wide range of experimental, comparative, and theoretical approaches, ecologists are starting to gain a detailed understanding of the long-term dynamics of vegetation. We explore how patterns of variation in demographic traits among species have provided insight into the processes that structure plant communities.

Feedbacks and landscape-level vegetation dynamics
Trends in Ecology & Evolution, 2015Alternative stable-state theory (ASS) is widely accepted as explaining landscape-level vegetation dynamics, such as switches between forest and grassland. This theory argues that webs of feedbacks stabilise vegetation composition and structure, and that abrupt state shifts can occur if stabilising feedbacks are weakened.

Vegetation dynamics induced by phreatophyte–aquifer interactions
Journal of Theoretical Biology, 2007The dynamics of phreatophyte vegetation are strongly coupled to those of the shallow phreatic aquifers from which phreatophytes extract water. Vegetation is able to influence the depth of the water table, which, in turn, can induce stress in vegetation.
