Abstract

Sustainability and environmental education are often taught through the Science discipline in the curriculum. The biological sciences accommodate much of the work students will do in learning about ecological, biological and sustainable practices and systems of the living world. This work is important, however, it can focus too heavily on content without paying attention to the natural environment to enable students to experience embodied and affective responses. Learning about the human body with/as nature is and should be an essential aspect of science education. Learning about the human body is typically achieved through the biological sciences curriculum and is not considered in relationship to the natural world and the environmental crisis. In science education we have the opportunity to consider our embodied relationship with/as the natural world and how this fundamental relationship may shift thinking of the environmental crisis as happening ‘out there’. This opportunity transforms our thinking from trying to fix the problem using exterior solutions to considering our responsibility as intrinsically connected human bodies. This research presentation explores the affective turn to consider how our embodied relationship with nature can be activated as an educational apparatus to enhance sustainable practices. Sustainable solutions cannot be considered devoid of the human body that is made of the same biological matter that forms the natural world. This presentation proposes an education that is embodied, affective and connected for a sustainable future world.

Abstract

Environmental pollution has shifted interest towards the development of bioplastics, which offer the dual benefits of utilizing waste and enabling cost-effective production of biodegradable materials. Polyhydroxyalkanoates (PHAs) are a class of biodegradable plastics synthesized intracellularly by various bacteria. Inexpensive carbon substrates such as PET, wastewater, agricultural waste, molasses, lauric acid, whey, cellulose, plant oils, and starch hydrolysates can serve as excellent feedstocks for PHA production, presenting significant economic advantages. PHAs have emerged as potential useful materials for different applications owing to their unique properties. The versatility of PHAs in terms of their non-toxic degradation products, biocompatibility, desired surface modifications, wide range of physical and chemical properties, cellular growth support, and attachment without carcinogenic effects have enabled their use as in vivo implants. Microbial production of PHAs also provides the opportunity to develop PHAs with more unique monomer compositions economically through metabolic engineering approaches. At present, it is generally established that the PHA monomer composition and surface modifications influence cell responses. PHA synthesis by bacteria does not require the use of acatalyst (used in the synthesis of other polymers), which further promotes the biocompatibility of PHA-derived polymers. We have stock of more than hundred bacterial stains which are able to produce Biodegradable plastic. Biodegradable plastic was extracted from bacterial strains, which were isolated from different environments of Pakistan. All the strains were analyzed for resistant markers. Extraction of PHA was done by different methods. PCR base strategy was used to amplify Pha biosynthesis operon. These studies are benefitting from the fact that the PHA polymer presents a great variety of characteristics in terms of its biodegradability, elasticity, non-toxicity, biocompatibility, ability to function as nanoparticles, and possibility for tailor-made physical-chemical properties.

Abstract

Coastal ecosystems such as seagrass beds and coral reefs are unique habitats at the interface between terrestrial and oceanic environments. Such ecosystems are among the most productive and dynamic ecosystems, which are highly sensitive to climate change including ocean warming and acidification. Calcifiers such as corals and sea urchins are suggested to be negatively affected by ocean warming and acidification. Meanwhile, macrophytes such as seagrasses and seaweeds are suggested to be positively affected by ocean warming and acidification, as the increase in temperature and CO2 concentration in seawater can potentially increase their photosynthetic rates and productivity. Here, some recent studies are introduced to explore how ocean warming and acidification affect calcifiers and macrophytes by conducting interaction studies. Ocean warming and acidification were negatively affected coral growth rate and sea urchin physiology, while photosynthesis and growth of seagrasses and seaweeds were particularly increased under ocean warming and acidification, thus potentially alleviating the negative effects of ocean warming and acidification. However, they do not always provide habitat refugia for calcifiers. Ocean warming and acidification are also suggested to modify the trophic interactions in coastal ecosystems. The present studies showed that ocean warming and acidification have the potential to shift the balance in coastal ecosystems and assessing the organism interactions is important to give a better understanding of the response of coastal ecosystems to climate change.

Abstract

Potential as a suitable habitat for turtles to settle and breed. The objective of this work is to assess the state of turtle nesting sites and evaluate the findings from turtle monitoring efforts in the Pieh Island Conservation Area. Observations were conducted directly from September 25th to September 30th, 2023. A quantitative method was employed. The materials that were utilized consist of green sea turtles (Chelonia mydas), hawksbill turtles (Eretmochelys imbricata), and olive ridley turtles (Lepidochelys olivaceae). The nesting habitat data encompasses information on the proximity of vegetation to the tidal limit, beach slope temperature and humidity levels, as well as the depth and quantity of eggs. Four stations serve as research sites. The distance of vegetation from the nests ranged from 7.6m to 13.4m, while the beach slope on Pandan Island varied between 3.62º and 6.19º. The temperature inside the nests ranged from 28ºC to 29.1ºC, with a humidity level of 77% to 88%. The nests had a depth of 50cm to 60cm. The results of this study show that Pandan Island Beach is a highly suitable site for turtle nesting.

Abstract

As times have changed, so have lifestyles that have adverse health effects, including obesity. Obesity is known to potentially affect the number of red blood cells in the body. Obesity can cause iron deficiency in children and adolescents, which can develop into anemia. The aim of this study was to determine the effect of obesity on the number of red blood cells and to investigate the effect of a combination of glucomannan and moringa leaf extract on the number of red blood cells in obese white Wistar strain rats. The research method used was a true experimental design in the form of a post-test only control group with three treatment groups: the control group, treatment group P1 and treatment group P2. The results of the calculations showed differences in the number of red blood cells in each treatment. In the control treatment, there were 7.16/L. In the P1 treatment, the RBCs were 3.24 million/L. In contrast, the P2 treatment yielded a result of 5.02 million red blood cells per liter. It can be concluded that the combination of Porang Tuber Glucomannan with Moringa Leaf Extract can reduce body weight and normalize the number of red blood cells.
