Hemispheric- and Continental-Scale Patterns of Similarity in Mountain Tundra
Understanding the full range of biodiversity patterns from local to global scales, through the study of the drivers of multiscale plant community composition and diversity, is a current goal of biogeography. A synthetic understanding of to what extent vegetation compositional patterns are produced by biotic factors, geography, or climate and how these patterns vary across scales is needed. This lack hinders prediction of the effects of climate ch…
Mediterranean‐Type Ecosystems
Mediterranean‐type ecosystems are biomes that are composed of plant and associated animal species adapted to warm, dry summers and mild, wet winters. These biomes are found in small areas around the Mediterranean Sea, in western Australia, on the southern tip of Africa, in Chile, and in California, USA, and Baja California, Mexico. The vegetation is dominated by evergreen sclerophyllous shrubs. Fire is a common ecological disturbance to which pla…
Biomes
The term “biome” is a level of biological classification with the most straightforward definition but the most varied applications. It is the unit of biogeography one conceptual step below the planetary biosphere, but the degree of division is a matter of choice. The concept is often used to illustrate basic relations between biogeographic patterns, emphasizing plant physiognomy, and climate. New work on microbiomes and anthropogenic biomes, as w…
Ecosystem
The term ecosystem is examined in terms of its varied usage. Ecosystems can imply a specific place or type of environment, a particular scientific approach to the study of environment, or general connectedness in the environment. The fluidity of usage can be confusing, but all varied uses serve varied, legitimate purposes.
Relations of Alpine Plant Communities across Environmental Gradients: Multilevel versus Multiscale Analyses
Alpine plant communities vary, and their environmental covariates could influence their response to climate change. A single multilevel model of how alpine plant community composition is determined by hierarchical relations is compared to a separate examination of those relations at different scales. Nonmetric multidimensional scaling of species cover for plots in four regions across the Rocky Mountains created dependent variables. Climate variab…
Predicting Avian Influenza Co-Infection with H5N1 and H9N2 in Northern Egypt
Human outbreaks with avian influenza have been, so far, constrained by poor viral adaptation to non-avian hosts. This could be overcome via co-infection, whereby two strains share genetic material, allowing new hybrid strains to emerge. Identifying areas where co-infection is most likely can help target spaces for increased surveillance. Ecological niche modeling using remotely-sensed data can be used for this purpose. H5N1 and H9N2 influenza sub…
Climate shocks and migration: An agent-based modeling approach
Multiscale Relationships Between Alpine Treeline Elevation and Hypothesized Environmental Controls in the Western United States
Multiple environmental factors contribute to the spatial and compositional character and elevational patterns of alpine treeline ecotones (ATEs), and the relative influence of these factors is scale dependent and spatially variable. Frameworks detailing the hierarchical structure of the ATE have been developed to characterize scale dependencies of the pattern and controls of treeline, but this topic has not been studied across a broad range of sc…
Predicting Functional Role and Occurrence of Whitebark Pine ( Pinus albicaulis ) at Alpine Treelines: Model Accuracy and Variable Importance
At some alpine treelines in the Rocky Mountains, whitebark pine (Pinus albicaulis)—a keystone species—plays a central role in tree island development through facilitation. Whitebark pine occurs both as a solitary tree and also as a component of tree islands, although relative importance of these two patterns varies geographically. We examine the utility of four predictive models to understand how the functional role of a keystone species varies s…
Riparian Landscapes
Neutral Landscapes: Bases for Exploration in Landscape Ecology
Neutral landscape models are computer-generated representations of the spatial pattern of habitat. Most are based on a grid of cells, although network (graph theory) representations are increasing. Representation of the landscape varies from binary (habitat - non-habitat) to nearly continuous. The motivations for this approach to the study of landscapes include concepts derived from island biogeography as well as the idea that computer experiment…
Complexity theory, spatial simulation models, and land use dynamics in the Northern Ecuadorian Amazon
Complexity at Advancing Ecotones and Frontiers
Ecotones, such as advancing treelines, have been examined as complex self-organizing systems. Frontiers of human settlement may share some of their spatial characteristics, because they too include feedbacks between spatial pattern and process. Advancing frontiers of three study areas in the Amazonian region of Ecuador are analyzed with the aid of Landsat imagery to detect change. Power-law distributions of advancing deforestation are found, whic…
Extinction-Debt Trajectories and Spatial Patterns of Habitat Destruction
Extinction-debt theory holds that following habitat destruction, some extant species in remnants of habitat are doomed to eventual extinction. The extinction debt will affect the interpretation of ongoing impacts and extinctions, because little is understood about the changes in species abundance through time in remnants following surrounding habitat destruction. In some models, thresholds in mean time to extinction are sensitive to the spatial c…
