postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Susceptibility of Oregon Forest Trees and Shrubs to Phytophthora ramorum:
Phytophthora ramorum is a recently established invasive pathogen in some mixed-hardwood forests of central coastal California (10,11) and extreme southwestern Oregon (5). It also is known from horticultural nurseries and landscape plantings in Europe (12) and recently was reported from a few nurseries in California and Oregon (6,9). Symptoms are dramatically different on different host species....
متن کاملAssessing the capacity of trees and shrubs species to accumulate of particulate matter (PM10, PM2.5 and PM0.2)
Background and Objective: Today, the presence and increase of particulate matter is one of the serious factors that threaten human health. In the meantime, trees can accumulate airborne particles by their foliage. In this study, the accumulating ability of various PM by the leaf of some tree and shrub species was evaluated in Isfahan. Materials and Methods: 12 species of trees and shrubs were ...
متن کاملWhen Trees Grow Low: Shrubs and Fast MSO1
Recent characterization [9] of those graphs for which coloured MSO2 model checking is fast raised the interest in the graph invariant called tree-depth. Looking for a similar characterization for (coloured) MSO1, we introduce the notion of shrub-depth of a graph class. To prove that MSO1 model checking is fast for classes of bounded shrub-depth, we show that shrub-depth exactly characterizes th...
متن کاملEstimation of species diversity of trees and shrubs using ETM+ sensor data (Case study of forests in Qalajeh Kermanshah province)
The use of remote sensing techniques as a suitable solution to estimate the levels of species diversity is of high importance for the sustainable management of forests. In order to investigate the potential of using sensor data from Landsat 7 ETM+ to estimate species diversity in the Zagros forests, digital data related to the August 7, 2002 from forests in the Qalajeh Kermanshah Province were ...
