The field of bioethics aims to ensure that modern scientific and technological advancements have been primarily developed for the benefits of humankind. This field is deeply rooted in the traditions of Western moral philosophy and socio-political theory. With respect to the view that the practice of bioethics in certain community should incorporate religious and cultural elements, this paper attempts to expound bioethical tradition of the Malay-Muslim community in Malaysia, with shedding light on the mechanism used by the National Fatwa Council to evaluate whether an application of biological sciences is ethical or not. By using the application of the genetically modified food as a case study, this study has found that the council had reviewed the basic guidelines in the main references of shari'ah in order to make decision on the permissibility of the application. The fatwa is made after having consultation with the experts in science field. The council has taken all factors into consideration and given priority to the general aim of shari'ah which to serve the interests of mankind and to save them from harm.
Theory-based evaluation (TBE) is an effectiveness assessment technique that critically analyses the theory underlying an intervention. Whilst its use has been widely reported in the area of social programmes, it is less applied in the field of energy and climate change policy evaluations. This paper reports a recent study that has evaluated the effectiveness of the national biofuel policy (NBP) for the transport sector in Malaysia by adapting a TBE approach. Three evaluation criteria were derived from the official goals of the NBP, those are (i) improve sustainability and environmental friendliness, (ii) reduce fossil fuel dependency, and (iii) enhance stakeholders' welfare. The policy theory underlying the NBP has been reconstructed through critical examination of the policy and regulatory documents followed by a rigorous appraisal of the causal link within the policy theory through the application of scientific knowledge. This study has identified several weaknesses in the policy framework that may engender the policy to be ineffective. Experiences with the use of a TBE approach for policy evaluations are also shared in this report.
Genetically modified organisms (GMOs) have increasingly dominated commodity crop production in the world in the endeavour to address issues related to food security. However, this technology is not without problems, and can give rise to bioethical issues for consumers, particularly Muslims. The Islamic perspective on GMOs is complex and goes beyond just the determination of whether food is halal or not. If the food is halal, but the process to obtain it is not thoyibban, as it is unethical, then the food cannot be permitted under the Maqasid al-Shari'ah. This paper examines ethical issues pertaining to GM crops and how the related ethical issues contradict with Islamic principles beyond the binary distinction between the contaminated and uncontaminated food. Since GM technology is a contemporary issue that may not be directly addressed in the al-Quran and Sunnah, other Islamic sources should also be referred to when drawing up this code of ethics to achieve the objective of Syariah (Maqasid al-Shari'ah). Maqasid al-Shari'ah can be applied to frame the Islamic bioethics guideline as it is comprehensive and encompasses moral principles directly applicable to modern biotechnology. The paper subsequently explores how the principles of Maqasid al-Shari'ah are applied in addressing these ethical issues.
Biotechnology policies and regulations must be revised and updated to reflect the most recent advances in plant-breeding technology. New Plant Breeding Techniques (NPBT) such as gene editing have been applied to address the myriad of challenges in plant breeding, while the use of NPBT as emerging biotechnological tools raises legal and ethical concerns. This study aims to highlight how gene editing is operationalized in the existing literature and examine the critical issues of ethical and legal issues of gene editing for plant breeding. We carried out a systematic literature review (SLR) to provide the current states of ethical and legal discourses surrounding this topic. We also identified critical research priority areas and policy gaps that must be addressed when designing the future governance of gene editing in plant breeding.
The relationship between β-diversity and latitude still remains to be a core question in ecology because of the lack of consensus between studies. One hypothesis for the lack of consensus between studies is that spatial scale changes the relationship between latitude and β-diversity. Here, we test this hypothesis using tree data from 15 large-scale forest plots (greater than or equal to 15 ha, diameter at breast height ≥ 1 cm) across a latitudinal gradient (3-30o) in the Asia-Pacific region. We found that the observed β-diversity decreased with increasing latitude when sampling local tree communities at small spatial scale (grain size ≤0.1 ha), but the observed β-diversity did not change with latitude when sampling at large spatial scales (greater than or equal to 0.25 ha). Differences in latitudinal β-diversity gradients across spatial scales were caused by pooled species richness (γ-diversity), which influenced observed β-diversity values at small spatial scales, but not at large spatial scales. Therefore, spatial scale changes the relationship between β-diversity, γ-diversity and latitude, and improving sample representativeness avoids the γ-dependence of β-diversity.
One mechanism proposed to explain high species diversity in tropical systems is strong negative conspecific density dependence (CDD), which reduces recruitment of juveniles in proximity to conspecific adult plants. Although evidence shows that plant-specific soil pathogens can drive negative CDD, trees also form key mutualisms with mycorrhizal fungi, which may counteract these effects. Across 43 large-scale forest plots worldwide, we tested whether ectomycorrhizal tree species exhibit weaker negative CDD than arbuscular mycorrhizal tree species. We further tested for conmycorrhizal density dependence (CMDD) to test for benefit from shared mutualists. We found that the strength of CDD varies systematically with mycorrhizal type, with ectomycorrhizal tree species exhibiting higher sapling densities with increasing adult densities than arbuscular mycorrhizal tree species. Moreover, we found evidence of positive CMDD for tree species of both mycorrhizal types. Collectively, these findings indicate that mycorrhizal interactions likely play a foundational role in global forest diversity patterns and structure.
