Deer impact and plant resistance traits
… and are now adults. Plant resistance traits (Leaf mass per area, Leaf dry matter content, C:N ratio, and Wood density) were tested and compared between low and high deer density area by using mixed effect statistical models. Leaf mass per area (LMA), leaf carbon-nitrogen ratio (C:N), and wood …

Discerning Differences in the Plant Traits of the Floral Communities of Mt. Washington, NH, by Incorporating Intraspecific Variability Analysis
… Here, I analyzed plant traits (plant height, leaf area, specific leaf area, and leaf dry matter content) of four herbaceous plants found growing atop Mt. Washington, NH in sheltered snowbanks. They are also found in the sub-alpine understory. I examined baseline differences between the alpine …

Demography and leaf physiology of Cornus drummondii in response to disturbance in tallgrass prairie
… unknown. Here, I measured ramet demography and leaf physiology of the clonal shrub Cornus drummondii in response to disturbance at the Konza Prairie Biological Station. I quantified the growth rate, reproduction, and ramet demography of C. drummondii in response to fire frequency, grazing, and …

Development of cassava (Manihot esculenta Crantz) leaf meal as an animal feed
… of developing cassava (Manihot esculenta Crantz) leaf meal as an animal feed. In feeding trials with broilers, improvements in performance were observed at 10% inclusion of cassava leaf meal (CLM). High levels (20 and 30%) of CLM depressed gain, feed intake and feed per gain. Weights of spleen and …

A functional analysis of the response of the Southern Kalahari dune vegetation to land-use intensity
… pressure. Plant height, spinescence, specific leaf area, leaf dry matter content, leaf sclerophylly and stem density were found to be examples of such traits. Phanerophyte and chamaephyte dominated functional groups were mostly associated with lower range condition and hemicryptophyte dominated …

Spatial variation in functional traits and grazing value of savanna grasses at the community and species level
… results from C3-dominated temperate grasslands, leaf dry matter content, specific leaf area and force to tear are not useful proxies of grazing quality. More broadly, this study highlights that there may be considerable intra-specific variation in grass grazing quality, but that this …

The Effects of Geography, Environment and Phylogeny on Community Assembly and Gene Flow Dynamics
… from the null model. The functional traits SLA, leaf dry matter content (LDMC), and maximum height also showed no clear pattern of spatial structuring. On the other hand, leaf area is strongly overdispersed across all spatial scales. Although leaf area overdispersion would be generally taken as …

Improving estimation of gross primary productivity of terrestrial ecosystems
… concepts of fractions of PAR absorbed by canopy, leaf and chlorophyll; (4) to explore the potential of estimating the fractions of PAR absorbed at different scales; and (5) to check if vegetation seasonal MODIS spectral variations during plant growing season are only due to vegetation's …
