...with further increase in population density of Rumex dentatus. It is concluded that yield and yield related parameters were adversely affected in case of higher infestation of Rumex dentatus as it competes with the major crop for resources and exhibits auto-toxicity when grown in association with wheat crop.

...natural populations, but population density, group density, and the frequency of cooperative breeding were lower in the two natural populations than in the habituated population. We conclude that the cooperative breeding system is a facultative breeding strategy in both natural and habituated buff-throated partridge, and suggest that variation in food resources might cause variation in demography and the frequency of cooperative breeding among populations.

...Pakistan to document the population density of this bee. It reveals the distribution and strength of population of in mainly hilly areas of Pakistan. The objective of this study is not only useful to upscale honey production by this hill bee but also for pollination purpose. People interviewed were of the opinion that there is still some potential for these bees. Abbottabad area was having comparatively more population of than other areas.

Most favored altitudinal range was 450 m to-550 m (asl). Population density was the highest (12 animals/km2) in October and lowest (7.4 animals/km2) in May. Dominant vegetation included Acacia nilotica (IV= 108.9), ...

The prevalence of chewing lice species of Coturnix coturnix was recorded as 44.47% Cuclotogaster cinereus (Nitzsh, 1866) belongs to family Philopteridae 32.64% Menacanthus abdominalis (Piaget, 1880) and 22.87% Menacanthus cornutus belongs to family Menoponidae. The results revealed high infestation found in birds of rural localities. The present stu...

For such purpose colony forming units (cfu) per gram of soil and seed were determined and capability of previously characterized M. phaseolina isolates to cause the disease was tested on HO-1 variety. Additionally, most virulent isolate was characterized through sequence and phylogenetic analysis. There was signifi...

Scat analysis for diet composition showed 5 domestic and 8 wild prey species in its diet menu, with major share (53 %) from livestock and relatively less (46%) from wild prey. The grey wolf has emerged as one of the major predator in the study area consuming mainly donkey, horse, cow, sheep and goats, resulting in a negative perception among the locals. Most of th...

The habitat analysis of study sites and correlation of species with habitat were done through Principal Component Analysis (PCA) by using software (XLSTAT-Ecology version). The habitat was positively correlated in the two areas while the study site Harighel fields was negatively correlated. It was also found that most species except for a few were positively correla...

Effect of some temperature changes on the population density of some plant parasitic nematode species
...ical fluctuations in the population density of some parasitic nematodes on plants viz., date palm and olive in both soil and roots was investigated. These nematodes were negatively correlated with the prevailing average soil temperature during four seasons (autumn= 20°C; spring= 22°C; summer= 27°C and winter= 14°C).

The population density was lowest in December on all varieties such as Nirala (1.0), Dilnasheen (2.1) and Bemisal (1.2), while maximum in November such as Nirala (3.8), Dilnasheen (6.6) and Bemisal (4.2) per leaf. Bemisal and Dilnasheen varieties had significantly higher jassid population per leaf as compared to Nirala variety on different sampling dates.

The sinking of marine snow aggregates is as an essential process for moving organic carbon source from the up-ward to down-ward in the ocean. Marine snow associated bacterial communities perform a crucial role in organic material degradation by producing extracellular hydrolytic enzymes and are considered as key components in global carbon cycle.
