Leaf N

The legume is notable owing to their symbiotic nitrogen (N) fixing ability. Usually, higher leaf N concentration and N to phosphorus (P) ratio (N:P) in legumes than non-legumes. However, the variations of leaf N, P and N:P and their relationship had been hardly studied based on functional groups. In this study, we studied the leaf N, P and N:P and their relationship among different functional groups. The results showed that the average values of leaf N, P and N:P ratios for all legumes were 27.33 mg g-1, 1.27 mg g-1 and 21.94, respectively. Leaf N (36.96 mg g-1) and P (2.15 mg g-1) of herbaceous legumes are significantly higher than N (24.97 mg g-1) and P (1.18 mg g-1) in woody plants, respectively. Moreover, leaf N, P and N:P of shrub markedly higher than them in tree. Leaf N and P are always higher in deciduous than evergreen legumes. A negative correlation was found between leaf N:P and P in overall and different functional groups of legumes.

Capture Rates

In this laboratory study we measured the independent effects of macrophyte growth form, plant density, and prey abundance on the foraging rate of the pumpkinseed sunfish (Lepomis gibbosus). We demonstrate that macrophyte growth forms are not all similar in their effects on fish foraging. Prey capture rates of pumpkinseeds foraging among Scirpus validus (cylindrical stems) were 53 and 365% times greater than for Potamogeton amplifolius (leafy stems) for cladoceran (Sida crystallina) and larval damselfly (Coenagrionidae) prey, respectively. Plant growth form influenced prey capture rates more than charges in natural plant density. Plant density effects ranged from none on damselfly capture rates to a 29% decline in cladoceran capture rate over a twofold increase in plant density. Our results indicate that in plant-structured habitats, variation in plant growth form can be an important determinant of fish foraging and habitat associations.

Tree Component

Diets of mule deer were studied in the Kamloops area from September to April. The forages of 67 rumen samples were sorted to grass, tree, shrub, and forb species and the percent oven-dry weights calculated for each. Polynomial regressions (to the third degree) were used to describe the use of each plant-growth form over time, as well as to determine the influence of snow depth on plant species consumption. Douglas fir formed most of the tree component of the diet of the deer. Consumption of this species was highest in December and January. Grass consumption was less than 10% until early spring when it increased to almost 100%. More forbs were consumed in fall than in winter, while shrubs were consumed more in early fall and late winter than in late fall. Species composition of each plant growth-form generally varied with season. Increasing snow depth altered the proportion of both small and large plants in the diet. As snow depth increased, fewer small plants but more large plants were consumed.
