Composition and structure of a Fagus orientalis-dominated forest managed with shelterwood aim (A Case study in the Caspian forests, northern Iran)
Composition and structure of a three-storied Fagus orientalis-dominated forest was investigated in the Caspian forests, north of Iran. Circular sampling plots of 1000 m2 occupied by advance growth and natural regeneration were randomly chosen where the initial cuttings (with shelterwood aim) were performed. Abundance of species at different growth stages and quality of seedlings and saplings we...
متن کاملBird and Mammal Problems in Southeastern Pine Forests
Birds and rodents eat pine seeds needed for regeneration, and the larger mammals destroy established seedlings by browsing or trampling. Some of the problems they cause have been solved or solutions are near; some still defy solution.

A historically unprecedented mountain pine beetle (MPB) outbreak affected western Montana during the past decade. We examined radial growth rates (AD 1860-2007/8) of co-occurring mature healthy and MPB-infected ponderosa pine trees collected at two sites (Cabin Gulch and Kitchen Gulch) in western Montana and: (1) compared basal area increment (BAI) values within populations and between sites; (...
متن کاملHabitat area and structure affect the impact of seed predators and the potential for coevolutionary arms races.
Both habitat patch size and structure affect the abundance and occurrence of species and thereby can affect the ecology and evolution of species interactions. Here we contrast the level of seed predation and selection exerted by Common Crossbills (Loxia curvirostra complex) and red squirrels (Sciurus vulgaris) in the extensive mountain pine (Pinus uncinata) forests in the Pyrenees with their le...
