The histochemical measurement of urea-resistant alkaline phosphatase from maternal blood neutrophils is known to have a high detection rate for the prenatal detection of Down's syndrome pregnancies. However, because the histochemical method is laborious and subjective to use, it has not gained widespread acceptance in prenatal screening programmes. We present a simple and objective method for the measurement of urea-resistant alkaline phosphatase by flow cytometry. The method should allow the design of larger studies aimed at evaluating the role of neutrophil urea-resistant alkaline phosphatase in the prenatal screening for Down's syndrome. 相似文献

The loss of livestock to wild predators is an important livelihood concern among Trans-Himalayan pastoralists. Because of
the remoteness and inaccessibility of the region, few studies have been carried out to quantify livestock depredation by wild
predators. In the present study, we assessed the intensity of livestock depredation by snow leopard Uncia uncia, Tibetan wolf Canis lupus chanku, and Eurasian lynx Lynx l. isabellina in three villages, namely Gya, Rumtse, and Sasoma, within the proposed Gya-Miru Wildlife Sanctuary in Ladakh, India. The
three villages reported losses of 295 animals to these carnivores during a period of 2.5 years ending in early 2003, which
represents an annual loss rate of 2.9% of their livestock holdings. The Tibetan wolf was the most important predator, accounting
for 60% of the total livestock loss because of predation, followed by snow leopard (38%) and lynx (2%). Domestic goat was
the major victim (32%), followed by sheep (30%), yak (15%), and horse (13%). Wolves killed horses significantly more and goats
less than would be expected from their relative abundance. Snow leopards also killed horses significantly more than expected,
whereas they killed other livestock types in proportion to their abundance. The three villages combined incurred an estimated
annual monetary loss of approximately $USD 12,120 amounting to approximately $USD 190/household/y. This relatively high total
annual loss occurred primarily because of depredation of the most valuable livestock types such as yak and horse. Conservation
actions should initially attempt to target decrease of predation on these large and valuable livestock species. 相似文献

In human-populated landscapes worldwide, domestic dogs (Canis lupus familiaris) are the most abundant terrestrial carnivore. Although dogs have been used for the protection of livestock from wild carnivores, they have also been implicated as predators of livestock. We used a combination of methods (field surveys, interview surveys, and data from secondary sources) to examine the patterns and factors driving livestock depredation by free-ranging dogs, as well as economic losses to local communities in a Trans-Himalayan agro-pastoralist landscape in India. Our results show that livestock abundance was a better predictor of depredation in the villages than local dog abundance. Dogs mainly killed small-bodied livestock and sheep were the most selected prey. Dogs were responsible for the majority of livestock losses, with losses being comparable to that by snow leopards. This high level of conflict may disrupt community benefits from conservation programs and potentially undermine the conservation efforts in the region through a range of cascading effects. 相似文献

Genotypic variation of nitrogen use efficiency in Indian mustard 总被引:1,自引:0,他引:1

This experiment was conducted to investigate the variation of nitrogen efficiency (NE), nitrogen uptake efficiency (UE), physiological nitrogen use efficiency (PUE) among Indian mustard genotypes, grown under N-insufficient and N-sufficient conditions. Nitrogen efficiency varied from 52.7 to 92.8. Seed yield varied from 1.14 t ha(-1) to 3.21 t ha(-1) under N-insufficient condition, while 2.14 t ha(-1)-3.33 t ha(-1) under N-sufficient condition. Physiological basis of this difference was explained in terms of nitrogen uptake efficiency and physiological nitrogen use efficiency, and their relationship with the growth and yield characteristics. While nitrogen uptake efficiency was positively correlated with plant biomass (0.793**), leaf area index (0.664*), and leaf nitrogen content (0.783**), physiological nitrogen use efficiency is positively correlated with photosynthetic rate (0.689**) and yield (0.814**). This study suggests that genotype having high nitrogen uptake efficiency and high physiological nitrogen use efficiency might help in reducing the nitrogen load on soil without any penalty on the yield. 相似文献

An emerging conflict with Trans-Himalayan pastoral communities in Ladakh’s Changthang Plateau threatens the conservation prospects
of the kiang (Equus kiang) in India. It is locally believed that Changthang’s rangelands are overstocked with kiang, resulting in forage competition
with livestock. Here, we provide a review and preliminary data on the causes of this conflict. Erosion of people’s tolerance
of the kiang can be attributed to factors such as the loss of traditional pastures during an Indo-Chinese war fought in 1962,
immigration of refugees from Tibet, doubling of the livestock population in about 20 years, and increasing commercialization
of cashmere (pashmina) production. The perception of kiang overstocking appears misplaced, because our range-wide density estimate of 0.24 kiang
km−2 (± 0.44, 95% CL) is comparable to kiang densities reported from Tibet. A catastrophic decline during the war and subsequent
recovery of the kiang population apparently led to the overstocking perception in Ladakh. In the Hanle Valley, an important
area for the kiang, its density was higher (0.56 km−2) although even here, we estimated the total forage consumed by kiang to be only 3–4% compared to 96–97% consumed by the large
livestock population (78 km−2). Our analysis nevertheless suggests that at a localized scale, some herders do face serious forage competition from kiang
in key areas such as moist sedge meadows, and thus management strategies also need to be devised at this scale. In-depth socioeconomic
surveys are needed to understand the full extent of the conflicts, and herder-centered participatory resolution needs to be
facilitated to ensure that a sustainable solution for livelihoods and kiang conservation is achieved. 相似文献
