    Results show effects of increasing heavy metal concentrations on nodulation development, especially the nodulation index (i.e., the number of nodules per gram of the total fresh biomass). A significant decrease in nodulation index was observed at about mg Cd kg −1, mg Zn kg −1, and mg Pb kg −1 in these soils.

Sawgrass density, biomass, and leaf area index: a flume study in support of research on wind sheltering effects in the Florida Everglades. [Nancy B Rybicki; Geological Survey (U.S.);]. NDVI is a measure of the greenness in a pixel area and has been used in various studies as a proxy for biomass, leaf area index, and vegetation health in both terrestrial and coastal environments.

Biomass, leaf area index (LAI), percent canopy cover (PCC), water content, and soil properties were also evaluated. LAI, PCC, and biomass were positively correlated between each other.

The greatest leaf length and width of Thalassia occur between 1 and 2 m. Stem density decreases with depth, yet biomass increases with productivity values of to g DW/m 2 per day, with the maxima occuring during the dry season (February). Forest canopy cover (CC), which is defined as the proportion of the forest floor that is covered by the vertical projection of the tree crown [], plays a major role in understanding the structure and health condition of forest ecosystems [].It is also a useful measure for evaluating the leaf area index (LAI), carbon stocks, tree density, and wildlife microhabitat [3,4,5,6].Cited by: 2.

- accumulation of combustible material (layer of leaf litter and debris on foest floor, dead trees, etc) - increase in understory growth (grass, shrubs, brush, ladder trees) - Larger trees develop - Even-aged stands develop - tree density increases.

We planned to collect three samples per habitat type per area per time period, for a total of 18 sweep nets and 18 leaf packs per habitat type. However, SAV and FAV were not present at all areas in March, and not all leaf packs were recovered due to high flows, vandalism, and loss, which resulted in a reduced sample : Rosemary Hartman, Stacy Sherman, Dave Contreras, Alison Furler, Ryan Kok.

Duke University Wetland Center researcher Jeff Johnson samples sawgrass biomass in the Everglades Water Conservation Area-2A along an environmental nutrient gradient to determine changes in plant productivity as influenced by nutrient additions.

Cover was significantly reduced after just 1 year of fertilizer treatments, and biomass and density were significantly reduced after 3 years of annual fertilizer treatments.

In Central México, wetland plants are harvested for weaving, fodder, and fertilizer. To test whether harvesting alters plant diversity, we compared the effects of harvesting all vegetation once, follow-up harvesting of Typha domingensis Pers.

The Sawgrass-Spikesedge-Beakrush-Black Bogrush-Aparejograss Herbaceous Vegetation Association, and Ashe Juniper_Bastard Oak-Plateau Live Oak Woodland Association is reported as new to the state. Ecology is the study of the interactions of living organisms with their environment.

One core goal of ecology is to understand the distribution and abundance of living things in the physical environment. Attainment of this goal requires the integration of scientific disciplines inside and outside of biology, such as biochemistry, physiology, evolution, biodiversity, molecular biology.

These attributes include local spatial density using area-weighted abundance measurements of cell concentration, cumulative length / biovolume / biomass C / and biosurface area, and spatial clustering based on descriptive statistics of the 1 st and 2 nd nearest neighbor distances.
