The Evergreen forest type develops along the Valdivian and North-Patagonian phytogeographical regions of the south-central part of Chile (38° S–46° S). These evergreen forests have been scarcely studied south of 43° S, where there is still a large area made up of old-growth forests. Silvicultural proposals for the Evergreen forest type have been based on northern Evergreen forests, so that the ...

Effects of fire suppression policies on semi-arid yellow pine and mixed conifer (YPMC) forests in the western US have been well documented, and restoration of forest structure and natural fire regimes are high management priorities to ensure the health and resilience of such forests. However, determining reference conditions for ecological restoration is difficult due to the near absence of und...

The genus Tropiocolotes comprises small, naked toed, ground dwelling and nocturnal desert geckos, ranging from Morocco and Mauritania in northern Africa to south and central Arabia as well as coastal Iran. Herein, we describe a new species of the genus Tropiocolotes from western Iran based on five specimens from Nayband region. This new taxon is described with a statistical approach based on 34...

Modification of stands’ structure and managing them using silvicultural methods close to nature and single selection system require information on status of structure, determining the target diameter, basal area and suitable volume to result in long-term equilibrium and sustainability. So, this study was conducted using the selection sample statistical method by selecting  five 1-ha sample plot...

Soil is one of the most important components in forests and distinguishing soil types and soil capability are first steps in forest management. The main aim of this study was to determine relationship between slope aspect and position, and chemical properties of the soil. Soil sampling was done in Tang-e-Dalab in Ilam province which is a part of southern Zagros. Samples were collected in both n...

—We compared roost site characteristics of the Indiana bat (Myotis sodalis) and northern bat (M. septentrionalis), which form maternity colonies in cavities and beneath bark of dead (snags) and living trees in eastern North American forests. We used published data (n 5 28 sources; n 5 1145 roost trees) from studies completed where the distributions of the two species overlap and evaluated a sui...

We surveyed birds and small mammals in 45 forest stands from southern Oregon, near Cave Junction, south into northern California, near Branscomb. Over this 350-km distance, we found 71 species of birds and 7 species of mammals that were common enough for detailed analysis. Fourteen species of birds and two mammals reached peak abundances in older (mature and old-growth) forests; however, none a...

BACKGROUND Self-citation is one of the main challenges in the evaluation of researchers' scientific output. This study aimed at comparing the institutional self-citation among the universities located in Northern Iran. METHODS This study was conducted as a scientometric study. Research population included all scientific productions of 16 Northern Iran Universities with at least 100 indexed do...
