An encrusting sponge, Terpios hoshinota, has the potential to infect all species of stony corals in shallow reefs and killing them. It caused a decline in coral coverage in two south-eastern islands of Taiwan. We proposed two hypotheses to examine how the sponges kill the corals, namely, light blocking and toxins, and tested by in-situ experiments. The results revealed that both light blocking, sponge toxins, and particularly the combination of both factors were effective at inducing tissue damage in stony corals over a short period. Second, to answer why the sponges killed the corals, we tested two hypotheses, namely, gaining nutrients versus gaining substrates for the sponge. By analyzing the stable isotopes ¹³C and ¹⁵N, as well as exploiting an enrichment experiment, it was possible to determine that only approximately 9.5% of the carbon and 16.9% of the nitrogen in the newly grown sponge tissues originated from the enriched corals underneath. The analysis also revealed that the control corals without isotope enrichment had higher δ¹³C and δ¹⁵N than the control sponges, which was an additional indication that T. hoshinota did not rely heavily on corals for nutrients. Therefore, our results support the hypothesis that the encrusting sponge did not kill corals for food or nutrients, but rather for the substrate.

In this digital era, young children spend a considerable amount of time looking at telephone, tablet, computer and television screens. However, preventative eye health behavior education could help avoid and relieve asthenopia. The effects of parental influence on their children’s eye health behavior through the preschool eye health education intervention program were examined. The Health Belief Model was used to develop parental involvement strategy and eye health curriculum. The study was conducted in a large public preschool with five branches in Beijing, China. A total of 248 parent–child pairs participated in the baseline and follow-up surveys, of which 129 were in the intervention group and 119 were in the comparison group. The generalized estimating equation analysis results indicated that parental involvement in preschool-based eye health intervention on screen uses had positive influence on parents’ eye health knowledge, cues to action, and parenting efficacy. The intervention program also had positive effects on the increasing level of children’s eye health knowledge, beliefs, cues to action, self-efficacy, and behaviors. The results supported the implementation of a preschool-based eye health intervention program with parental involvement, which could potentially enhance children’s and parents’ eye health beliefs and practices.

Farm ponds or irrigation ponds, providing a vital habitat for diverse bird communities, are an environmental feature with characteristics that cross over typical urban and natural conditions. In this study, the species richness and community structure of irrigation ponds were characterized on the local and landscape scales. Within a landscape complex in the Taoyuan Tableland of Taiwan, 45 ponds were surveyed, ranging in areas from 0.2 to 20.47 ha. In total, 94 species and 15,053 individual birds were identified after surveying four times. The association between ponds and birds was determined to establish the effect of pond dimensions on species richness and community composition in the complex by comparing the responses of functional groups to pond configurations. Seven avian functional groups were identified. Compared with landbirds (i.e., families Alcedinidae, Apodidae, Icteridae, and Sturnidae), waterbirds (i.e., families Anatidae, Ardeidae, Charadriidae, Podicipedidae, and Scolopacidae) exhibited a stronger correlation with pond variables. Our study provides substantial evidence that these artificial ponds have influenced wintering waterbirds. The final results of this study may help stakeholders and land managers identify areas not to establish large-scale solar facilities considering waterbird habitats in pond areas.

Citizen science has become a major source of scientific research in recent years. Many studies have concluded that citizen science projects not only contribute to the sciences but also considerably improve the scientific and environmental literacy of participating volunteers (citizen scientists). A dynamic citizen science project can accomplish goals that benefit society but it is difficult to establish, operate, and maintain a citizen science project. This paper reports a case study and examined the most famous citizen science project in Taiwan, the Taiwan Roadkill Observation Network (TaiRON), with the viewpoint of a community of practice learning theory. Community of practice theory is widely used in education and business management research and is an important framework for knowledge exchange and dissemination. Through content analysis, observation, and interviews with the moderator of the TaiRON project, this study explored how its internal operations reflected the principles of community of practice theory. The results indicated that TaiRON members developed a set of shared working methods and jointly completed certain actions. All participating members possessed in-depth knowledge or enthusiasm with respect to their specific focus areas, enabling them to meaningfully contribute to work on specific topics. The three major elements of a community of practice—domain, community, and practice—should be aligned with the community’s purpose and action. We discovered that the TaiRON citizen science project was consistent with the elements of the theory of community of practice. In particular, the establishment of TaiRON was enabled by scientific and technological advances; therefore, this paper discusses the characteristics of virtual communities of practice. Moreover, TaiRON contributed to raising the public’s environmental literacy. This paper reports pilot research concerning citizen science operations and may stimulate related future research.

Citizen science projects are considered popular and efficient approaches to scientific research and conservation of sustainability. In addition, much research suggests that citizen science can improve participants’ environmental and scientific literacy when they participate in surveys over a period of time. However, considerable research indicates that people in short-term training programs do not change their environmental literacy significantly. Nevertheless, studies have stated that these results might result from inappropriate evaluation methods. In this study, we used personal meaning mapping (PMM) to evaluate participants’ knowledge, attitude, and behavior intention in relation to land crab protection. This method merges quantitative and qualitative dimensions, used in scientific knowledge research, which we extend to evaluate attitude and behavior intention. As a result, even with short-term training, we observe that participants’ knowledge, attitude, and behavior intention significantly improves. Although some individuals exhibit no change in certain respects, we use PMM to understand the causes in detail. Taiwan is an island, famous for its fertile landscapes and biodiversity, and we anticipate finding efficient means to improve public environmental literacy. According to our research, public engagement in citizen science projects is an excellent approach to environmental education and conservation for sustainability.
