Impacts of SCUBA divers in the Silfra groundwater fissure : ecological disturbance and management
… underwater behavior to assess the mechanisms and ecological consequences behind diver-related ecological disturbances and 4) analyzing perceptions and experiences of dive company operators, dive-guides, dive-tour customers and the Thingvellir National Park officials surrounding the use of Silfra …

Fire, flooding, and felids: Deer and puma spatial ecology and predator-prey interactions in dynamic, subtropical wildlands
Cyclic and extreme ecological disturbances have the capacity to alter resources and thereby animal populations. Interactions between disturbance and resource availability can influence predator-prey interactions. Predator-prey responses to ecological disturbance may be more pronounced in herbivores …

Carabid Beetle Ecology as a Function of Disturbance in Temperate and Tropical Forests
Ecological disturbance is an episodic event which causes temporary disruption to components integral to structure and function of an ecosystem. With the majority of today’s forests recovering from past disturbance, knowledge of the changes and patterns of forest species in relation to disturbance …

The Effect of Environmental Perturbations on the Plant Phyllosphere Microbiome
Applying ecological concepts to microbial communities has proved to be challenging, often revolving around the relative importance of stochastic and deterministic processes applied heterogeneously across the habitat in time or space. The phyllosphere is the aboveground surface of plants on which …

A cost effectiveness analysis of preventative mitigation options for wildland urban interface homes threatened by wildfire
… (SIAM) with wildfire probability results from an ecological disturbance model (SIMPPLLE). Analysis of western Montana study area data reveal that nearly all of the structure ignition probability results modeled with extreme wildfire weather for visited homes are 1.0. This contrasts the low …

Application of disturbance theory to assess impacts associated with a three-dimensional seismic survey in a freshwater marsh in southwest Louisiana
… various practical and theoretical aspects of disturbance in a coastal wetland marsh in southern Louisiana. A literature review approached disturbance ecology from both practical and theoretical perspectives and assessed its applicability to developing broad predictive models. However, specific …

Field and laboratory studies suggest that recruitment of the invasive common carp is controlled by native fish in Stable Lakes of the Upper Mississippi Basin.
… Basin is limited to areas that experience an ecological disturbance that alters the fish community. It has been hypothesized that recruitment of carp is limited by native predatory fish and that carp are only able to recruit in habitats where these native species have been excluded due to …

Bees, Bombs, and Burns: Disturbance and the Native Bee Communities of Military and Other Public Lands in Virginia
Physical and ecological disturbances caused by military land use can create and maintain early successional habitats, which can support diverse communities of native plants and animals. These lands may serve as refugia, protecting rare, threatened, and endangered species that may have disappeared …

Effects of anthropogenic and natural disturbance on sedimentary organic matter quantity, nutritional quality and degradation in river, lagoon, and coastal marine ecosystems
Ecological disturbance can play a fundamental role in regulating habitats’ structure and biodiversity. Aquatic ecosystems, especially lagoons and marine coastal areas, appear to be more sensitive to anthropogenic and natural disturbances than terrestrial ones, whose ecological consequences are more …

Monitoring and management of tourist landing sites in the Maritime Antarctic
… Orkney and South Shetland Islands), Antarctica's ecologically richest area. This study is founded on the author's five years of research, both at a field station and as a shipboard expedition leader. The programme formed part of a longer study of polar tourism, Project Antarctic Conservation, …

The effects of habitat disturbance, host traits, and host physiology on patterns of gastrointestinal parasite infection in black howler monkeys (Alouatta pigra)
Anthropogenic forest disturbance associated with the conversion of forest into monocultures for agricultural production or cattle ranching, and the increased human presence linked to wood extraction and selective logging, can alter host-parasite dynamics and increase the risk of infectious diseases …
