Abiotic Controls on Long-term Windthrow Disturbance and Temperate Rain Forest Dynamics in Southeast Alaska
We investigated the role of abiotic factors in controlling patterns of longterm windthrow in the pristine coastal temperate rain forests of southeast Alaska. Our objectives were to test the extent to which long-term patterns of windthrow can be predicted spatially at the landscape scale by using four abiotic factors (slope, elevation, soil stability, and exposure to prevailing storm winds), eva...
متن کاملQuantifying ecosystem geomorphology of the southern Appalachian Mountains
Geomorphology is a dominant factor influencing vegetation distribution in the southern Appalachians, and quantifying landform characteristics is increasingly important for forest ecosystem classification. This study used slope gradient and two previously published geomorphic indices, terrain shape index and landform index that quantify landform shape and protection, to develop a field-based lan...
متن کاملSpatial patterns of ecohydrologic properties on a hillslope-alluvial fan transect, central New Mexico
Spatial patterns of soil properties are linked to patchy vegetation in arid and semi-arid landscapes. The patterns of soil properties are generally assumed to be linked to the ecohydrological functioning of patchy dryland vegetation ecosystems. We studied the effects of vegetation canopy, its spatial pattern, and landforms on soil properties affecting overland flow and infiltration in shrubland...
متن کاملEcologically-Relevant Maps of Landforms and Physiographic Diversity for Climate Adaptation Planning.
Key to understanding the implications of climate and land use change on biodiversity and natural resources is to incorporate the physiographic platform on which changes in ecological systems unfold. Here, we advance a detailed classification and high-resolution map of physiography, built by combining landforms and lithology (soil parent material) at multiple spatial scales. We used only relativ...
متن کاملLinking irreplaceable landforms in a self-organizing landscape to sensitivity of population vital rates for an ecological specialist.
Irreplaceable, self-organizing landforms and the endemic and ecologically specialized biodiversity they support are threatened globally by anthropogenic disturbances. Although the outcome of disrupting landforms is somewhat understood, little information exists that documents population consequences of landform disturbance on endemic biodiversity. Conservation strategies for species dependent u...
