Data of this study were collected from primary and secondary sources. Primary sources of data were collected using two sets of structured questionnaires. A total number of three hundred （300） questionnaires were administered on categories of respondents in this study. Results of this study revealed that food crops are the major crops cultivated in the study area, and the effects of climate change on agricultural production results in soil loss, plant nutrient loss, textural change, increase in pest and diseases and poor yield germination etc.. This study therefore recommended that cover trees should be planted, which will provide shade and reduce heat, due to climate change and the preservation of underground water.展开更多

To investigate this, variability in the timing of river entry in three historical Finnish Atlantic salmon populations were analyzed using salmon trap data collected during 1870- 1902. The analyses reveled that 1 ） the timing of river entry differed substantially and consistently among the rivers, and that 2） variation among the rivers was much larger than variation among years. Annual variations were not explained by regional environmental conditions, whereas in one river the timing of the local flood peak was a significant predictor of the timing of river entry. Differences in the timing of salmon entry to geographically closely situated rivers suggests that a regionally fixed opening date for coastal fisheries might not be the best management strategy as it may lead to uneven exploitation of salmon populations from different rivers [ Current Zoology 55 （5） ： 342 - 349, 2009] .展开更多

Cross-sectional consumer data were collected through a survey. One thousand seven hundreds and sixteen （1,716） Muslim respondents all over Peninsular Malaysia were interviewed randomly via structured questionnaire in 2009 to address the issues on Muslim consumers＇ understanding and perspective of Halal principles and its relation to food safety, environmentally friendly and animal welfare. Descriptive and Chi-square analysis were used to analyze the data collected. The findings revealed that majority of respondent relate Halal principles to food safety because Halal principle not only about slaughtering of animals but must also be Tyoibah or clean. The consumers from East of Peninsular Malaysia, with higher level religiosity and education level are more likely to understand the true meaning of Halal principles, Measuring the extent of consumers＇ understanding of Halal principles is vital, since Halal does not only focus on the Islamic processing but also sustainable concept of hygiene, sanitation and safety.展开更多
