Abstract:

The study considers the problem of decision-making in the actvites of agricultural enterprises in conditons of environmental uncertainty. The problem is formalized as a multcriteria conditonal optmizaton problem. The novelty of the work is that the factors are considered as dynamic fuzzy quanttes. The choice of the best alternatve is made between the elements of a predetermined fnite set of alternatves. Based on this formalizaton of the decision-making task, six requirements to the informaton system of decision support in the conditons of ecological uncertainty are formulated.

Abstract:

A blooming of Microcytis aeruginosa occurred in Maninjau Lake in 2000. Mass fish killed happened frequently due to deterioration of water quality in this lake. This study is aimed to observe the current environmental condition, fishery resources status and the state of development process of comanagement regime in Maninjau Lake. Water quality parameter such as temperature, conductivity, turbidity, pH and dissolved oxygen (DO) were measured in situ by using Horiba U-10 water checker. Total nitrogen, ammonia, nitrate, nitrite, total phosphorous, orthophosohate and chlorophyll-a parameter were analyzed using standard method. Phytoplankton was analyzed by Lackey Drop Microtransect. Fish samples were obtained from fishers’ catch. Fisheries data were collected by enumerator, through Focus Group Discussion (FGD), and questioner list methods. Stakeholder analysis was conducted by focus group interview and discussion. In general, water quality parameters were suitable for the life of aquatic organisms except for DO and ammonia. These parameters indicated that the water quality of lake was still undergoing degradation process. Maninjau Lake is rich of nutrient as indicated by abundance of blue green algae. Bada fish (Rasbora argyrotaenia) is an important commodity and the fisheries significantly contributes to local people’ income. Current fisheries problems indicate the urgency of the management and conservation efforts. Several stakeholder groups showed their interest in management. The increment of institutional sustainability concern was reflected by the emergence of local wisdom and the demand for participatory development and management.

Abstract:

The frequency of antlerless adult female caribou (Rangifer tarandus groenlandicus) was studied in four separate populations in west Greenland. Between the herds antlerlessness varied from 21% to 79%. An inverse relationship between winter range quality and percentage of unantlered cows is demonstrated. Relationship between calf percentage and maternal antler status was studied in one population and antlerless cows showed higher reproductive rate than antlered ones. In another population antlerless cows were almost absent outside the calving area. Calves of antlerless mothers were more susceptible to diseases and had significantly higher summer mortality than other calves, 42% and 27% respectively. The relative importance of factors influencing antler development under various environmental conditons are assessed and a close relationship between antlerlessness, physical condition, lactation, and length of period between calving and midsummer is discussed.

Abstract:

Abstract The aim of the study was to assess the economic effectiveness of pike (Esox lucius L.) stocking based on the value of fish caught with commercial fishing gears and the value of stocking material introduced into 44 lakes in the Ełk Lake District in northeastern Poland. The effectiveness of stocking is presented against the background of lake environmental conditions in the context of their natural potential for pike populations to inhabit and develop in them. The data analyzed regarded the size and value of catches and stocking from 1996-2017 that was obtained from an entity authorized to exploit fisheries. Information on selected lake morphometric, morphological, and environmental parameters was also obtained from this source. The value of pike catches in the analyzed period was characterized by a high, stabile level, and the stocking level increased. The indicator of the stocking economic effectiveness was at a high average annual level in excess of 3.9 PLN of catches per 1.0 PLN for stocking, but it decreased during the period analyzed. The high stocking effectiveness in the studied lakes was determined by, inter alia, natural conditions, stocking material quality, properly performed stocking, and efficient exploitation. However, it can be concluded that it is mainly stocking that maintains pike catches at a high, relatively stable level in the lakes analyzed. Additionally, new methods of pike population management are discussed, e.g., catch and release.

Abstract:

In vitro cold storage of Rubus germplasm was investigated using several environmental conditons and types of storage containers. Shoot cultures of Rubus species and cultivars were grown in either tissue culture bags or 20 × 150 mm glass tubes and compared for plant condition and survival under various storage conditions. Cultures stored at 10 C in the dark were in poor condition after 6 months. Cultures kept at 4 C were in much better condition and had higher survival rates after 18 months when stored with a 12 h daylength rather than total darkness. Overall there were no differences in survival or condition between cultures in tubes and bags. Contamination rates were 15% in tubes and 0% in bags. Plants in tissue culture bags could be stored for 9 months at 25 C with 16 h light when the nitrogen level of the MS medium was reduced to 25% and the medium volume was increased from 10 to 20 ml per bag. Genotype differences were apparent under all conditions tested. The best storage condition for Rubus germplasm was 4 C with 12 h light. Plastic tissue culture bags were preferred over tubes due to lower contamination rates.

Abstract:

The population differences in ecology and behaviour of reindeer (Rangifer tarandus spp.) is closely paralleled by the characteristic features of reindeer husbandry which reveals the close relationship between behaviour and husbandry. The western portion of the reindeer husbandry region in the USSR is vast. The reindeer are maintained on a semi-loose basis; the herd is scattered over the range; the social activity of the reindeer is lower; the herdsmen gather the herd using dogs, the herdsmen migr.ate together with the herd during the summer, grazing the herd in the vicinity of the tent for 2-5 days at a time. In the eastern portion of the region (Yakutia, Chukotka, Kamchatka), the ranges are more restrictive; the reindeer are grazed in a compact mass in summer; their feeding and movement are rigidly regulated; their social activity is high; the herd is gathered in foot without dogs. In summer, herdsmen follow the herd with light tents, the place of grazing being changed almost daily. In the taiga reindeer are raised mostly for transportation, although the hides and meat are also important; the reindeer are bigger, tamer and can be used for riding. The herds are small and the management of them is aimed at retaining the reindeer near home or the camp; migrations are short; often forest reindeer husbandry is of a sedentary nature. Attempts to change the pattern of reindeer husbandry and the methods of herding are not always successful. The harmony of environmental conditons, morphology, physiology, ecology and behaviour of reindeer and methods of husbandry are more easily disrupted than altered.

Abstract:

Malaria remains one of the most devastating vector-borne parasitic diseases in tropical and subtropical regions. Approximately 40% of the world’s population lives in malaria endemic areas mostly in developing countries. The estimated global incidence is about 225 million cases and 80% of these cases occur in sub-Saharan Africa. The approximated global deaths due to malaria every year is about 700,000 people and 90% occur in Africa. In South Africa, parts of Mpumalanga, Limpopo and KwaZulu-Natal have endemic malaria. The incidence of malaria in South Africa by province is 56, 2 cases per 100,000 population at risk; 31,1 cases per 100,000 population at risk and 3,3 cases per 100,000 population at risk for Mpumalanga; Limpopo and KwaZulu-Natal, respectively. Approximately 80% of the cases are imported from malaria endemic countries and diagnosed in the South African health facilities. It is therefore important that these cases are disentangled from local cases using environmental or climatic conditions as proxy measures especially in light of South Africa eradication goal. Methodology Secondary data used in this study were obtained from Mpumalanga Department of Health, South African Weather Services, Statistics South Africa and Global Climatic Research Units. These data were analysed from 2001 to 2010 to determine the correlation between surrounding climatic or environmental conditions and malaria incidence in Mpumalanga Province. The Pearson correlation was used to assess for significant correlations between malaria incidence and environmental or climatic conditions. A negative binomial regression model was used to identify and quantify factors significantly association with malaria risk. The Kulldorff spatial and space-time scan statistic was used to detect significant clustering of malaria cases in space and space-time. Results The incidence of malaria has decreased significantly since 2001 to 2010 in Mpumalanga Province. The decline has been observed from 1,304 cases per 100,000 population at risk in 2001 to less than 200 cases per 100,000 population at risk in 2010. About 96% of malaria cases were reported from Ehlanzeni District and less than 4% were reported from Gert Sibande and Nkangala Districts. The temperature, rainfall and humidity were statistically significant in all months from all years (p<0.05). The temperature, rainfall and humidity had a significant positive correlation with malaria cases. An excess of 1,752 and 104 malaria cases were detected in May and June over time when using weather stations data. When using remote sensed data, an excess of 1,131; 3,036; 4,009; 994 and 235 cases were observed from March, April, May, June and July, respectively. Discussion and conclusion The significant positive correlations between malaria cases and temperature, rainfall and humidity suggested that for an increase in each unit factor, malaria cases also increases. The excess number of cases observed especially during the winter season, suggested the likelihood of the importation of those cases. These results were in accordance with results from previous studies.
