Coastal sedge/grass meadow restoration in a peri-urban wetland via alteration of environmental filters: can hydrological constraint be trumped?
… taxa survivorship and richness by altering environmental conditions, such as elevation and soil moisture. However, a higher than expected rate of subsidence and rapidly diminishing elevations point to potentially shifting system dynamics that require further exploration.

The diversity of ground bryophyte communities along an altitudinal gradient on La Réunion island
… communities are structured according to "environmental filters". The mid-domain effect and mass effect could not be used to describe the changing diversity along the altitudinal gradient, however a correlation analysis revealed temperature and relative humidity influences the changing a …

Connections between individual dispersal behavior and the multi-scale distribution of a saproxylic beetle
… interactions) with hierarchically-organized environmental filters to predict the incidence of Odontotaenius disjunctus (Passalidae), a saproxylic (=decayed wood dependent) beetle common to eastern North American forests, at multiple spatial scales. In dispersal experiments, O. disjunctus …

Community ecology of aquatic insects in forested headwater streams in the southern Appalachians
… Niche assembly emphasizes the role of environmental gradients as filters that organize a metacommunity by locally selecting colonizers with similar functional traits, whereas dispersal assembly emphasizes the importance of source pool characteristics and dispersal limitation in …

Aerosol Optical Depth And Its Relationship To Radar Derived Precipitation In Mali, West Africa
… cells are used in the analysis. In addition, environmental filters are applied so that only cases with large Convective Available Potential Energy (CAPE) and weak 0 to 6 km Above Ground Level (AGL) vertical speed shear are included in the analyzed dataset to increase the likelihood of isolated …

Floristic homogenization and impoverishment : herb layer changes over two decades in deciduous forest patches of the Weser-Elbe region (NW Germany)
… that is expected to be particularly affected by environmental alterations are herb layer plant communities of fragmented forests such as those in the west European lowlands. However, our knowledge about current changes in species diversity and composition in these communities is limited due to a …

FACTORS DETERMINING HABITAT SELECTION BY SPRING MIGRATING WATERFOWL ALONG THE WABASH RIVER, ILLINOIS
… this chapter encouraged investigation into how environmental factors shape the formation of local duck communities are structured from regional pools. In the third chapter of this dissertation I investigate the relationship between local and regional waterfowl community structure and how this …

Trait-based approaches to understanding the response of forest understory herbs to environmental variation
… and communities will respond to future environmental change. Trait-based approaches can thus offer valuable insights into how populations and communities will respond to environmental change by providing a mechanistic link between plant traits and the environment. This dissertation …
