Vegetation response to disturbance in a coastal marsh in Texas

Disturbance is considered one of the main factors influencing plant species composition and diversity. We conducted a field study to address the plant community response in a coastal marsh to a major disturbance. In 1992, muskrats (Ondatra zibethicus L.) completely removed vegetation within a 450 ha area of intermediate coastal marsh in Texas, USA. We used vegetation data collected prior to the...

Full Polarimetric Emissivity of Vegetation-Covered Soils: Vegetation Structure Effects

In May 1999 the SMOS Earth Explorer Opportunity mission was selected by ESA to provide global soil moisture and sea salinity maps using the MIRAS L-band aperture synthesis interferometric radiometer. At this frequency there is a high dynamic range of the soil moisture signature and surface roughness effects are small, as well as vegetation effects. However, they cannot be neglected at large obs...

Effect of Vegetation Structure on Bird Vocalizations

In preparing for my presentation, I was recommended several review articles from compilations on bird vocalizations. I based much of my presentation on this particular review. It is a bizarre combination of a little bit of ethology and a good many predictions on how environmental features should influence the evolution of characteristics of bird song such as frequency, amplitude, modulatory emp...
