A study was carried out in National Agriculture Research Centre, Islamabad during autumn 2004 and 2005 to determine the variability and association among 9 traits in 139 soybean genotypes. The traits viz., days to maturity, plant height at maturity, number of branches per plant, number of pods per plant, 100-seed weight (g), oil content, grain yield per plant (g), biological yield per plant (g) and harvest index were studied. Results of analysis of variance showed significant differences among genotypes in terms of traits under study, which indicate the existence of genetic variation. Correlation coefficient indicated that the grain yield was positively and significantly correlated with all studied traits except plant height, which showed non-significant association during both years. Oil content showed significant and positive correlation with grain yield, 100-seed weight, and harvest index while significantly negative correlation were observed with days to maturity, plant height and number of branches per plant. Significantly positive correlations were observed for: days to maturity and plant height and number of branches per plant; number of branches per plant and number of pods per plant; number of pods per plant and biological yield per plant and harvest index; 100-seed weight and oil content; harvest index and 100-seed weight and biological yield per plant. Results obtained from this study can make better choice for soybean breeders for selecting genotypes among large number of accessions. Source

Distribution of the rodents in different areas of pothwar regions was recorded from January to October, 2014 using snap traps. A total of 179 rodents viz. B. bengalensis (n = 2), M. musculus (n = 50), M. booduga (n = 10), M. ameltada (n = 3), S. smurinus (n = 10), G. ellioti (n = 2), T. indica (n = 22), R. rattus (n = 50), R.norvegicus (n = 30) were captured during 468 trap nights with (trap success: 0.38). Simpson Index was (0.2), Shannon Winner Index (2.54), and Berger- Parker Dominance Index was (0.27). Averages of 3.3 rats per farm house were recorded with Rodent Index values (0.011). © 2015 Pakistan Agricultural Scientists Forum. All rights reserved. Source

Present studyPresent study on Lepidopteran diversity was conducted over some 52 km2of Tolipir National Park during summer, 2014 using line transects sampling method. A total of20 butterfly species belonging to two Nymphalidae and Pieridae families were recorded. The Various diversity indices, i.e. Simpson Index (0.09), Shannon Winner Index (3.05), Berger-Parker Dominance Index (0.06), Margalef’s Index (3.27), Menhinick Index (0.89), Buzas and Gibson's Index (0.96) were also calculated. The Lepidoptera diversity decreased along elevation gradient (1,400 – 2,600 m asl). This study will help in understanding the total energy flow in the ecosystem and in ensuring the soil fertility of Tolipir National Park. © 2015, Pakistan Agricultural Scientists Forum.All rights reserved.

In present study, we examined the wetlands avifaunal diversity of the Tolipir National Park to provide the baseline data of about species composition, and distribution. Field surveys were conducted during February 2013to February 2014. Data was collected by point count method. In total, a total of 202 bird species belonging to 55 families two vulnerable (Tragopanmelanocephalus, Catreuswallichii), one near threatened (Coracias garrulous), one endangered (Falco peregrines), and one rear species (Falco cherrugmilvipes). Various diversity indices Simpson index(0.0067), Shannon Wiener index (2.22) were also calculated. We assume that focusing the conservation practices upon these species will promote the preservation of a wide range of organisms inhabiting Tolipir National Park. © 2015 Pakistan Agricultural Scientists Forum.
