...rrounding landscape, and succession of the natural wild vegetation. Livestock grazing, cutting, harvesting (for fuel wood and animal feed) and burning of field boundary vegetation are common practices that affect rodents and their habitat. During crop season, local farmers in the Pothwar agro-ecosystem in Pakistan do not manage wild vegetation on the field edges, and that may impact rodent populations near their fields. This study was conducted to examine the ...

...ian model based on plant succession and climax (Friedel, 1991, Laurenroth & Laycock, 1989). New thoughts are provoked on the way of this discussion and new ideas and approaches are emerging. The necessity of new ecological models was realized keeping in view the limitations of the successional model in meeting the management objectives of a particular range resource in a given set of ecological conditions. The paper reviews ...

...vegetation and secondary succession. In May, 1978 vegetation in the exclosed and adjacent grazed areas was sampled to detect change in vegetation. Average yield and species composition of grasses, forbs and trees/shrubs were not significantly different in the exclosed and adjacent grazed areas. The higher ( P = 0, 05) forage production and composition of Aristida depressa in the grazed area showed that this species increased under continued grazing. Fre...

...tial stages of secondary succession on an
abandoned field in Peshawar were studied. Cyperus
rotundus was the pioneer species which dominated the old
field in the first autumn. In summer, Conyza bonariensis
shared the dominance with C. rotundus. The spring
vegetation was dominated by Coronopus didymus. Of the
total 45 species recorded in four seasons, only 13.3
percent were found to be exclusively confined to spring
season. I...

Bone marrow examination, counting myeloid cells to nucleated red blood cells revealed significant differences (P < 0.05) between the negative control group and the other groups, where the myeloid cells to nucleated red blood cells after induction of aplastic anemia in adult male dogs decreased from 2 on day 0 to 0.61 On day 15 for the positive control group, from 2.13 to 0.8 for the first group, and from 2.1 to 0.3 for t...
