Determining landscape parameters influencing species richness of habitat patches is one of the most important issues in conservation biology. Many previous studies have investigated the influence of habitat parameters on bird assemblages in forest patches, but studies seeking effects of oasis parameters on bird assemblages are very scarce. Karkas Protected Area is located in semi-arid zone in...
BACKGROUND Group dynamics of gregarious ungulates in the grasslands of the African savanna have been well studied, but the trade-offs that affect grouping of these ungulates in woodland habitats or dense vegetation are less well understood. We examined the landscape-level distribution of groups of blue wildebeest, Connochaetes taurinus, and Burchell's zebra, Equus burchelli, in a predominantly ...
the purpose of this study was to investigate the impacts of forest-based activities on the conditions of the ganaveh woodland in the southern zagros, iran, and to suggest strategies for improving the implementation of forest resource management plans. woodland inventory data was gathered in 2003, accompanied with data from interviews in 2008, were used in this study. the results show that there...
acres, and you enjoy a variety of activities on your land: watching wildlife, hiking, hunting, picking berries, picnicking or taking photos of wildlife and wildflowers. You delight in the beauty and solitude that comes with owning a woodland. You warm yourself in late fall and winter by cutting a little firewood, and you wouldn’t mind making a little extra cash, though managing your woodland fo...
The effect of isolation of forest habitat islands on the number of breeding woodland birds was studied in thirty-six woodlots, varying in size and differing in degree of isolation. Various isolation variables were calculated. Multiple regression analysis showed that, apart from patch area, the amount of woodland near the forest island and the distance t o an extensive forest area have significa...
As part of the Cultural Resource Management (CRM) evaluation process, fifty (50) Woodland ceramic sherds were selected by the Ft. Bragg (North Carolina) archaeological staff. The sherds were chosen so that they might give a sense of the range of variation that may exist within a single drainage and the differences that may exist between the river drainages (Table 1). The three river drainages i...
Petaurus gracilis (De Vis, 1883) is a gliding possum commonly known as the mahogany glider. This species is endemic to open sclerophyll woodland between Tully and Ingham in North Queensland, Australia. Within its distribution P. gracilis occurs in forests dominated by trees of the genera Eucalyptus, Corymbia, Melaleuca, and Acacia. This species is recognized as an endangered species because of ...
The relationship between vegetation and soil moisture deserves attention due to its scientific importance and practical applications. However, the effects of soil moisture on vegetation development and succession are poorly documented. Here we study soil water storage in Yanhe watershed at northern Shaanxi on five different land uses, namely shrubland, farmland, natural grassland, woodland, and...
