Purpose -This paper aims to explore stakeholder perspectives of the role of a campus eco-garden in education for sustainability (EfS). It will combine the perspectives to highlight a powerful learning environment (PLE) for university students to realize the concept of EfS.Design/methodology/approach -Semi-structured interviews were conducted to reveal stakeholder understandings of a campus eco-garden, as well as its associated expectations of learning activities and education outcomes. Three stakeholder groups were interviewed; designers, educators and environmental and non-environmental subject-related students.Findings -All three stakeholder groups expected cognitive learning of EfS to be enhanced by the eco-garden. The use of affective learning was not strongly expected by the stakeholders. Psychomotor learning was believed to be the most difficult to realize. To fulfill the potential of the eco-garden in EfS, all stakeholders suggested learning activities and roles for both students and teachers. The combined perspectives of the stakeholders helped to visualize a PLE to aid EfS.Practical implications -This study underlines the importance of effective communication of expectations between stakeholders. It underlines the importance of integrating educational activities with the eco-garden as a PLE, highlighting the roles of teachers and students. It also sheds light on the importance of introducing a cultural component to the EfS program.Originality/value -This is the first study to apply the PLE theory to enhance EfS with the aid of infrastructure. Both users and designers reveal their views on the planning of the campus eco-garden, especially in its educational function. The study is possibly the first to reveal the differences in expectations between designers and other stakeholder groups (teachers and students) using Könings et al.'s (2005) combination-of-perspectives model.

Shark conservation has become a focus of current international conservation efforts. However, the misunderstanding of sharks and their negative public portrayal may hinder their conservation. More importantly, the consumption of shark fin, which is very common in Chinese cultures, poses a significant threat to sharks. Hong Kong has long been the world’s largest shark fin trading center. Shark conservation would become more sustainable if public understanding of this predatory fish and an appreciation of its ecological significance could be promoted. It is possible that the demand for fins could be effectively managed through long-term educational efforts targeted at younger generations. To provide essential baseline data for planning of these educational efforts, this project investigated the perceptions of 11 to 12 year-old primary school students in Hong Kong about sharks, and their understanding of ecological concepts and shark-related knowledge. The findings indicate that these students lack sufficient knowledge and possess misconceptions about sharks and their ecological significance in the marine ecosystem. The students’ conceptual understanding level is strongly correlated with their perceptions. Correlational analyses further demonstrated a positive association between formal education and perceptions toward shark conservation. The students who favoured shark fin consumption did so because of its tastiness, whereas concerns about shark population decline and the cruelty of shark hunting were the main reasons for not favoring shark fin consumption. This pilot study provides preliminary but important insights into primary school education regarding the conservation of sharks.

Abstract. The kuruma shrimp Penaeus japonicus Bate, 1888 (Decapoda : Penaeidae) is economically important in the global shrimp market. It was regarded as the only species in the subgenus Marsupenaeus. However, our previous molecular analyses revealed two cryptic species (Forms I and II) in this species complex. In this study, we confirm the phylogenetic relatedness between the two cryptic species; revise their taxonomic status; and review their range distribution. The name Penaeus pulchricaudatus Stebbing, 1914 (with type-locality off the eastern coast of South Africa), previously considered as a junior synonym of P. japonicus, is fixed for Form II through a neotype selection. P. japonicus (Form I) is only confined to the East China Sea (including Japan, its type-locality) and the northern South China Sea. P. pulchricaudatus is widely distributed in the South China Sea, Australia, the Red Sea, the Mediterranean, and the western Indian Ocean. Phylogenetic analysis shows that P. japonicus is genetically homogeneous yet P. pulchricaudatus exhibits a strong phylogeographical structure. The Mediterranean stock of P. pulchricaudatus originated from the Red Sea population, supporting the Lessepsian migration hypothesis. The presence of two closely related cryptic species in the P. japonicus species complex provides important insights into fishery management and aquaculture development.

This study explored the survival and growth of the marine amphipod Hyaie crassicomis under different conditions of ambient temperature and salinity in the laboratory. In 96-h exposure experiments at a salinity of 30, //. crassicamis tolerated temperatures between 6 and 28 C C>90% survival). The 96-h LT50 value (median lethal temperature) at high temperature range for the amphipod was 32 C. The values at low temperature range for adults and juveniles were 3.2 and 4.2 C, respectiveiy, indicating that adults have a higher tolerance to low temperature than juveniles. At 25 C, the amphipods tolerated salinities between 10 and 50 (with >80% survival in 96 h). The 96-h LS^o values at high and low sahnity ranges were 56 and 2, respectively. Growth of the juveniles ft'om instars 1 to 6 was determined under different combinations of temperature and salinity. Growth rate of juveniles culrured at 25 C and a salinity-of 20 was the highest (0.114 mm day ') among the combinations of 15-25 C and 10-40 salinity. The moult increment of body length was afFected by both temperature and salinity. Yet the intermoult duration ofthe amphipods was affected by temperature only but not by salinity.

Balanus balanus Linnaeus, 1758, the model organism in the order Sessilia (Crustacea: Maxillopoda) is a cold water acorn barnacle in the family Balanidae distributing over the entire northern hemisphere. We present complete mitochondrial genome of this barnacle and analyze mitochondrial genomic characters of the family Balanidae. The length of mitochondrial genome is 15,955 bp, which is larger than those of the other barnacles in the same family. An inversion of a six-gene block (trnPro- nad4L- nad4- trnHis- nad5- trnPhe) is found between B. balanus and two Megabalanus (M. ajax and M. volcano). Three types of mitochondrial gene arrangements revealed in Balanidae have indicated the non-conserved gene orders even at intrafamilial level. Compared to pancrustacean ground pattern, large-scale gene rearrangements are found in B. balanus. Translocations of at least six tRNAs (trnAla, trnGlu/trnSer(AGY), trnPro/trnThr, trnLys, trnGln and trnCys) are identified and translocation and inversion occurred simultaneously in one tRNAs (trnTyr).
