Forest stands volume estimation by using Finnish Multi-Source National Forest Inventory in Stołowe Mountains National Park

Soil mites (Acari, Mesostigmata) from Szczeliniec Wielki in the Stołowe Mountains National Park (SW Poland)

The species composition of mesostigmatid mites in the soil and leaf litter was studied on the Szczeliniec Wielki plateau, which is spatially isolated from similar rocky habitats. A total of 1080 soil samples were taken from June 2004 to September 2005. The samples, including the organic horizon from the herb layer and litter from rock cracks, were collected using steel cylinders (area 40 cm2, d...

Rarity and Diversity in Forest Ant Assemblages of Great Smoky Mountains National Park

We report on a systematic survey of the ant fauna occurring in hardwood forests in the Great Smoky Mountains National Park. At 22-mixed hardwood sites, we collected leaf-litter ant species using Winkler samplers. At eight of those sites, we also collected ants using pitfall and Malaise traps. In total, we collected 53 ant species. As shown in other studies, ant species richness tended to declin...

Fire regimes and forest structure in a sky island mixed conifer forest, Guadalupe Mountains National Park, Texas, USA

Fire is a key disturbance agent in the fire-prone mixed conifer and ponderosa pine forests of the southwestern United States. Human activities (i.e., livestock grazing, logging, and fire suppression) have resulted in the exclusion of fire from these forests for the past century and fire exclusion has caused changes in forest structure and composition. This study quantifies spatial and temporal ...
