The tree species density and basal area form structural functional variables of healthy forest ecosystems. Tree are among useful parameters for management natural resources. A study was carried out in Image Forest Reserve (IFR) 2019 to determine area. total 170 plots measuring 20 m x 40 were set along the land cover types at an interval 250 from each other. Trees with a diameter breast height (...

The Douglas-Þr beetle, Dendroctonus pseudotsugae Hopkins, causes considerable mortality in Douglas-Þr, Pseudotsuga menziesii (Mirb.) Franco, forests. Within-stand distribution of mortality was examined in affected stands using geostatistical techniques. A 10 3 10 m grid was established in two 4-ha study sites. Live and beetle-killed host basal area was measured at each node. In a 16-ha stand, a...

The degree of naturalness was assessed in 37 mature (stand age 80−198 yrs) Norway spruce dominated stands located in southern Finland by measuring the number (0−610 ha–1) and basal area (0−33 m2ha–1) of cut stumps. The Johnson’s SB distribution was fitted for living spruce trees to describe the dbh-frequency and basal area-dbh distributions. Regression models were constructed for predicting the...

This study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. In this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (GALT) in chicken were selected. One hundred an...

Crown and canopy structurecorrelate with growth efficiency and also determine stem size and taper as described by the uniform stress principle of stem formation. A regression model was derived from this principle that expresses basal area increment in terms of the amount and vertical distribution of leaf area and change in these variables during a growth period. This model was fit t o data coll...

We used retrograde transneuronal transport of neurotropic viruses in Cebus monkeys to examine the organization of basal ganglia and cerebellar projections to two cortical areas on the medial wall of the hemisphere, the supplementary motor area (SMA) and the pre-SMA. We found that both of these cortical areas are the targets of disynaptic projections from the dentate nucleus of the cerebellum an...
