In recent years, there have been negative developments such as deforestation, overgrazing, and loss of plant species due to the mining and pasture misuse, and global warming. Due to this, the immunity of Mongolian livestock has been decreasing. The uses of immunosuppressive drugs is limited in the veterinary practice. The aim of this study, the technology of 3 types of drugs prepared from the different type of medical plants and their immunotropic activity was tested in the laboratory animals. In the result, the immunotropic activity of 1th group preparation /SL (50), AS (30) and OPG (20)/ was higher than control group and also other group preparation.    Дархлаа тэтгэх үйлдэлтэй эмийн бэлдмэлийн иммунотроп үйлдлийг судалсан дүн Сүүлийн жилүүдэд уул уурхайн олборлолт, бэлчээрийг зөв зохистой ашиглахгүй байх, дэлхийн цаг агаарын дулаарал зэрэгтэй холбоотойгоор бэлчээр хомсдох, талхлагдах, ургамлын төрөл, зүйлийн тоо хомсдох зэрэг сөрөг үзэгдэл ажиглагдах боллоо.

Climate change refers to the increase in greenhouse gases and changes in all kinds of climate with global warming. Concentration of CO2, one of the greenhouse gases, in the atmosphere increased over the 30% during the last 50 years, and this increase is expected to increase more rapidly at the next century. Climate change can lead to changes in temperature and precipitation. Flora is also varying in parallel to the climate change. In some part of the world, the number of plant species is decreasing, and it is expected that the number of the plant species adapting cool climates will decrease even further since these species cannot adapt to high temperatures. Climate change is importantly affecting yield of the grasslands. Higher increase in productivity in the western hemisphere in compared to the Eastern Hemisphere shows vulnerability of the grassland in North America, Central Asia, Central Africa and Oceania to the climate change. Global warming in areas with high summer temperatures affects feed consumption efficiency, live weight gain, milk yield and reproduction of the animals negatively. In cool regions, the effect of global warming is less felt. Intensive efforts are being made to investigate and predict the effects of climate changes on the grasslands. Detailed modeling studies are needed to make high predictions about the future. According to the forecasts made, it is predicted that global warming will be effective especially in Turkey. For this reason, drought tolerant varieties of forage plants should be developed and forage plant species with C4 photosynthesis adapting to different ecological regions of our country should be determined as well as the researches on the growing and breeding techniques of those plants should be conducted.

Abstract S. asiatica is a hemiparasitic plant, native to Africa and Asia. In common with most other parasitic weeds, it is not especially invasive in natural vegetation, but is much feared in crop land where infestations can build up to ruinous levels, especially with repeated growing of susceptible cereal crops. For this reason it is included in almost all lists of noxious, prohibited plant species. It has recently been reported in Queensland, Australia. There is also evidence for its continuing spread and intensification within a number of countries in Africa in particular in rice in Tanzania and maize in Malawi. A study by Mohamed et al. (2006) suggests that on the basis of climatic data, there are many territories into which Striga species, including S. asiatica, could be introduced and thrive. Global warming could further increase this potential.

Sem Study

It is the most effective way to study the effect of global warming on plant morphology by analyzing a plant species on a mount along altitudinal gradients. Altitudinal increase means decrease of temperature and metabolic rate as well. This might affect the leaf morphology greatly. The SEM study reveals that the size of nanopore on the epidermis changes gradually along altitudinal gradients, and the absorbed fine particles on the leaf have almost same size, exhibiting high selectivity over other particles. The study gives a strong proof that morphology change links to global warming.

The Impact

In high-altitude habitats, an increase in temperature and greater precipitation in the form of rain represent climate changes typically associated with global warming. We determined whether phenotypic plasticity and genetic changes in the mean phenotype could affect the adaptation of flowering time to changes in the environment resulting from global warming in a montane plant species, Aquilegia coerulea James. We collected seeds from 17 plants from each of three natural populations. For each of these 51 families, we assigned 3–4 individuals to each of four water and temperature treatments. We observed phenotypic plasticity in flowering time in response to both temperature and water availability but no genetic variance or genetic differentiation in phenotypic plasticity. These results indicate that phenotypic plasticity could provide a quick response to environmental changes but provides little evolutionary potential. In contrast to phenotypic plasticity in flowering time, the mean flowering time did vary among families and among populations, suggesting a genetic basis to flowering time and adaptation in the different populations. The most likely scenario for the adaptation of this plant species to climate change is a rapid response via phenotypic plasticity followed by selection and micro-evolutionary changes in the mean phenotype.

Background Global warming can cause variation in plant functional traits due to phenotypic plasticity or rapid microevolutionary change. Seed mass represents a fundamental axis of trait variation in plants, from an individual to a community scale. Here, we hypothesize that long-term warming can shift the mean seed mass of species. Methods We tested our hypothesis in plots that had been warmed over 18 years in alpine meadow communities with a history of light grazing (LG) and heavy grazing (HG) on the Qinghai-Tibet plateau. In this study, seeds were collected during the growing season of 2015. Results We found that warming increased the mean seed mass of 4 (n = 19) species in the LG meadow and 6 (n = 20) species in the HG meadow, while decreasing the mean seed mass of 6 species in the LG and HG meadows, respectively. For 7 species, grazing history modified the effect of warming on seed mass. Therefore, we concluded that long-term warming can shift the mean seed mass at the species level. However, the direction of this variation is species-specific. Our study suggests that mean seed mass of alpine plant species appears to decrease in warmer (less stressful) habitats based on life-history theory, but it also suggests there may be an underlying trade-off in which mean seed mass may increase due to greater thermal energy inputs into seed development. Furthermore, the physical and biotic environment modulating this trade-off result in complex patterns of variation in mean seed mass of alpine plant species facing global warming.
