Effects of Late Summer Fire on Tallgrass Prairie Microclimate and Community Composition
WO tallgrass prairie sites with different grazing histories and fuel accumulation were burned to investigate vegetation response to wild fires of differing intensity. Headfires were ignited 5 September 1985 under wildfire weather conditions (37 C air temperature, 36% relative humidity and wind gusts to 40 km/h). One of the burned plots had not been grazed for the past 3 years and had 1000 g/m2 ...
متن کاملBiomass-diversity responses and spatial dependencies in disturbed tallgrass prairies.
Monotonic, hump-shaped and zero-correlation productivity-diversity relationships have been found to date in many ecosystems. This diversity of responses has puzzled ecologists in their search for general principles on ecosystem functioning. Some state that the scale of observation is crucial in defining this relationship. We have developed a spatial model of tallgrass prairies where biomass and...
متن کاملBreeding Bird Communities Associated With Tallgrass Prairies in Southeast Nebraska
39 Introduction Within Nebraska, the Tallgrass Prairie Ecoregion occupies the approximate eastern one–third of the state and was historically characterized by extensive grassland habitats with scattered areas of upland deciduous forests and savannas, and lowland prairie or deciduous forests along riparian drainages (Kaul et al. 2011, Schneider et al. 2011). A nearly complete conversion of tallg...
متن کاملPriority effects of early successional insects influence late successional fungi in dead wood
Community assembly is an integral process in all ecosystems, producing patterns of species distributions, biodiversity, and ecosystem functioning. Environmental filters and colonization history govern the assembly process, but their relative importance varies depending on the study system. Dead wood decomposition is a slow process, allowing decomposer communities to develop within a slowly chan...
متن کاملArbuscular Mycorrhizal Fungal Networks Vary throughout the Growing Season and between Successional Stages
To date, few analyses of mutualistic networks have investigated successional or seasonal dynamics. Combining interaction data from multiple time points likely creates an inaccurate picture of the structure of networks (because these networks are aggregated across time), which may negatively influence their application in ecosystem assessments and conservation. Using a replicated bipartite mutua...
