Mangrove Reforestation

Mangrove reforestation is often carried out in various regions or regions, but information about the relationship of environmental factors and the distribution of fauna associations is still very minimal. The Principal Component Analysis (PCA) study on the correlation of environmental factors and the spatial distribution of the molusks community in the Seribu Islands mangrove reforestation area was conducted in March 2014 with the aim of analyzing environmental factors for the diversity and presence of the molusks. Environmental factors are measured insecurely, while the moluccan community is collected by making line transects and plots measuring 10 x 10 m2 and in the size of 10 x 10 m2, a small plot of 1 x 1 m2 is made. The results of the study show that environmental factors are not so different between stations and do not exceed the quality standard for the lives of 4 species of mollusks, where the parameters of aquatic pH are the environmental factors that most influence their distribution.Keywords: environmental factors, distribution, mollusks community, mangrove reforestation, Seribu Islands

The effort of leptospirosis prevention in Sleman currently only limited to counseling and treatment of the patient, while the patient search, ways of transmission of leptospirosis from rats to humans, have never implemented in an integrated manner. The study aimed to investigated the relationship between the environmental residential condition with the risk of leptospirosis in Sleman Regency. The research used a survey method  with case control study design. The results showed that environmental factors, which are not proved to have a relationship with the risk of leptospirosis were residential condition ({p=0,108} OR=3,818 {95%CI:0,922–15,811}), the trash bin condition ({p=1,000} OR=1,138 {95%CI:0,420–3,081}) and the sewer condition ({p=0,415} OR=0,551 {95%CI:0,187–1,624}). Environmental factors that associated with the risk of leptospirosis was the presence of rats ({p=0,001} OR=13,594 {95%CI:2,754–67,107}). The effort should be made in order to prevent the increasement of Leptospirosis cases by sanitation improvement and avoiding direct contact with rats as well as it litter. The Government should be pay more attention in the vector control programs, especially in leptospirosis prone areas so the prevention effort to be able run effectively and efficiently.

The Relationship

A total of 1,457 clean fleece weights, representing 7 years of production and adjusted for certain environmental factors, were used in this study. The data were analysed to determine the relationship of clean fleece weight to age in the Rambouillet, Romnelet, and Canadian Corriedale breeds of range sheep maintained under Western Canadian conditions.In general, maximum fleece weight was attained by the second year of production and was maintained until the end of the fourth year in all breeds. At that time a significant (p <.01) decline occurred which continued until the end of the seventh year. Among the Rambouillet and Romnelet ewes which were born and raised as singles, a small additional increase in average fleece weight occurred in the third year. Ewes born and raised as singles tended to produce more wool than twins but the differences were significant (p <.01) only in the Romnelet shearlings. The data suggest that in twins maximum production occurred at a slightly earlier age and that the subsequent decline began sooner than in singles.

BackgroundBulimia nervosa is typically defined as the combination of the behaviours of binging and vomiting. We sought to clarify the relationship of these behaviours from a genetic epidemiological perspective.MethodUsing data on the lifetime history of binging and vomiting from a personally interviewed population-based sample of female twins (n = 1897), we applied bivariate twin modelling to estimate the sources of variation for these traits.ResultsThe association between having ever binged (23.6%) and having ever induced vomiting (4.8%) was very strong (odds ratio=8.78, P < 0.0001). The best-fitting model indicated that lifetime binging and vomiting were both heritable (46% and 72%) and influenced by individual-specific environmental factors (54% and 28%). The overlap between the genetic (ra = 0.74) and individual-specific environmental factors (re = 0.48) for the two traits was substantial. No violations of the equal environment assumption were evident.ConclusionsIncluding binging and vomiting under the rubric of bulimia nervosa appears to be appropriate. Our data are consistent with the identification of binging and vomiting as complex traits resulting from the interplay of multiple genes and individual-specific environmental influences. In contrast to ‘environmentalist’ theories, our results suggest that genetic influences may be of particular relevance to the aetiology of binging and vomiting.

The Relationship

An extensive survey of the literature on grass distribution throughout the world has been made to determine the average percentage of species of each of the major grass tribes in the total grass flora. These average percentages for the six largest tribes are as follows: Agrosteae 8.2 per cent. Eragrosteae 8.1 per cent. Andropogoneae 11.9 per cent. Festuceae 16.5 per cent. Aveneae 6.3 per cent. Paniceae 24.7 per cent. The distribution of each of the above tribes is shown on world maps, and the relationship of this distribution to climatic, historical, and taxonomic factors is discussed. It is shown that the present distribution of each of the major tribes can be explained by a few readily recognizable factors. Climatic factors are of primary importance in relation to grass distribution and winter temperature has special significance.
