Accurately estimating forage biomass is essential for understanding the nutritional value of vegetation communities wild herbivores. However, clipping, drying, and weighing by species requires substantial labor, which restricts size number plots that can be sampled over a large geographical area. Labor-intensive sampling effort reduced using double strategy pairs visual estimates horizontal cov...

Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis Beetle & Young) communities frequently are mowed in an attempt to increase perennial herbaceous vegetation. However, there is limited information as to whether expected benefits of mowing are realized when applied to Wyoming big sagebrush communities with intact understory vegetation. We compared vegetation and soil nutrient concentr...

Several methods exist for extracting plant phenological information from time series of satellite data. However, there have been only a few successful attempts to temporarily match satellite observations (Land Surface Phenology or LSP) with ground based phenological observations (Ground Phenology or GP). The classical pixel to point matching problem along with the temporal and spatial resolutio...

Cain, M.D., 1991. Hardwoods on pine sites: competition or antagonistic symbiosis. For. Ecol. Manage., 44: 147-160. Early development of natural loblolly (Pinus taeda L.) and shortleaf pine (Pinus echinata Mill.) regeneration was monitored in two research studies and two research demonstrations between 1980 and I989 in southern Arkansas. Site preparation and hardwood control incorporated the use...

We provide the first description of the effects of local vegetation and landscape structure on the fruit-feeding butterfly community of a natural archipelago of montane rainforest islands in the Serra do Espinhaço, southeastern Brazil. Butterflies were collected with bait traps in eleven forest islands through both dry and rainy seasons for two consecutive years. The influence of local and land...

Th e interplay betw een plant-plant interactions and light heterogeneity in the understory of tropical forests has rarely been examined. We aimed to identify the relative importance of the understory light environment and terrestrial bromeliads in explaining the abundance and spatial organization of diff erent plant life forms along a coastal forest gradient from seashore inland in southeastern...

The forests of the San Bernardino Mountains have been subject to ozone and nitrogen (N) deposition for some 60 years. Much work has been done to assess the impacts of these pollutants on trees, but little is known about how the diverse understory flora has fared. Understory vegetation has declined in diversity in response to elevated N in the eastern U.S. and Europe. Six sites along an ozone an...
