Effects of Variable Fire Severity on Forage Production and Foraging Behavior of Moose in Winter
The increasing frequency and extent of wildfires in Alaska over the last half century has spurred increased interest in understanding the role of post-fire succession on vegetation establishment. Our primary goal was to examine how wildfire affects production and distribution of winter forage for moose (Alces alces) in interior Alaska, and how these changes in forage availability control forage...
متن کاملForage Quality of Calligonum comosum in Three Phenological Growth Stages (Case study: Kashan Rangelands, Iran)
Determination of forage quality of plant species in natural habitats such as rangelands and deserts is one of the most important factors for grazing management of these ecosystems. For this purpose, the nutritional values of Calligonum comosum in three phenological stages (vegetative growth, flowering, and seedling) were determined in desert habitats located in the northeast of Kashan, Iran (in...
متن کاملForage quality of three life forms of rangeland species in semi arid and semi humid regions in different phenological stages
For determination of grazing capacity, information of forage quality is essential which is influenced by various factors. The main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. Species were two grasses (Bromus tomentellus and Dactylis glomerata), two forbs (Ferula ovina and Coronil...
متن کاملVariations in Forage Quality of Two Halophyte Species, Camphorosma monspeliaca and Limonium iranicum at Three Phenological Stages
This study was conducted to compare forage quality of two native halophytespecies Camphorosma monspeliaca and Limonium iranicum collected from Meighansaline rangelands near Arak city in center of Iran. Edible biomass of both species wassampled on three phonological stages (vegetative growth, full flowering and seedripening). Forage quality indices such as Crude Protein (CP), Dry Matter Digestib...
متن کاملHyperspectral characteristics of canopy components and structure for phenological assessment of an invasive weed.
Spectral reflectance values of four canopy components (stems, buds, opening flowers, and postflowers of yellow starthistle (Centaurea solstitialis)) were measured to describe their spectral characteristics. We then physically combined these canopy components to simulate the flowering stage indicated by accumulated flower ratios (AFR) 10%, 40%, 70%, and 90%, respectively. Spectral dissimilarity ...
