The Role of Disturbance in Natural Communities
Two features characterize all natural communities. First, they are dynamic systems. The densities and age-structures of populations change with time, as do the relative abundances of species; localExpand
On the Evidence Needed to Judge Ecological Stability or Persistence
To see whether real ecosystems (as opposed to model ones) are stable, i.e., whether they exhibit resistance to short-term perturbations or adjustment following them, stable equilibria must beExpand
Amphibian Declines: Judging Stability, Persistence, and Susceptibility of Populations to Local and Global Extinctions
Extinctions are normal biological phenomena Both mass extinctions in geological time and local extinc- tions in ecological time are well documented, but rates of extinction have increased inExpand
Comparison of IKONOS and QuickBird images for mapping mangrove species on the Caribbean coast of Panama
Mangrove stands of differing species composition are hard to distinguish in conventional, coarse resolution satellite images. The new generation of meter-level satellite imagery provides a uniqueExpand
EXPERIMENTAL INVESTIGATIONS OF DISTURBANCE AND ECOLOGICAL SUCCESSION IN A ROCKY INTERTIDAL ALGAL COMMUNITY
Mechanisms of ecological succession were investigated by field experiments in a rocky intertidal algal community in southern California. The study site was an algal-dominated boulder field in the lowExpand

  • 1 December 1979
The effects of disturbance on local species diversity were investigated in an algal- dominated intertidal boulder field in southern California. In this habitat, the major form of disturbance occursExpand
Environmental drivers in mangrove establishment and early development: A review
Mangroves have a global distribution within coastal tropical and subtropical climates, and have even expanded to some temperate locales. Where they do occur, mangroves provide a plethora of goods andExpand
Intertidal Mosaics: Patch Size, Propagule Availability, and Spatially Variable Patterns of Succession
Localized disturbances transform most assemblages of sessile organisms into mosaics of patches differing in characteristics such as size and age (time since last disturbed). This mosaic nature ofExpand
Host life history and the effect of parasitic castration on growth: a field study of Cerithidea californica Haldeman (Gastropoda: Prosobranchia) and its trematode parasites
Abstract The prevalence of parasitic infection by larval digenetic trematodes in natural populations of the mud snail, Cerithidea californica Haldeman, was found to increase with snail length; allExpand
Integration of object-based and pixel-based classification for mapping mangroves with IKONOS imagery
TLDR
We compared the suitability of three types of data (SPOT XS, Landsat TM, CASI) in mapping mangrove species with five different classification approaches. Expand
