Planting a Seed of Experience - Long Term Effects of a Co-curricular Ecogarden-Based Program in Higher Education in Hong Kong.

This paper reports on the long-term effectiveness of a non-formal co-curricular educational program based on a campus ecogarden at a Hong Kong university in developing pro-sustainability awareness, attitudes and behavior among undergraduate students. This service-based, nature-based experiential learning program, termed the Ecogarden Farmer and Biodiversity Surveyor, has been running at the university since 2015. The program is divided into two consecutive phases: a training phase comprising various learning activities and a successive internship phase consisting of the all-round practical tasks involved in managing the garden. A retrospective evaluation of the program using phenomenographic approach and content analysis was adopted to reveal the diversity of students' learning experience, as the indicators of the success of the program. Of 112 participants from 4 cohorts, 32 completed online questionnaires, and semi-structured interviews were successfully conducted with twelve participants, three from each of the four cohorts. The results indicated that the program's outcomes could be categorized into five themes. Most outcomes fit into the theme 'an increase in knowledge and skill level,' followed by 'rise in environmental awareness,''facilitation of personal growth,' and 'enhancement of career development.' Many structural experiences revealed may suggest the success of the program. The longer the participants had participated in the program, the more in-depth and diversified reflection of the senior participants relating to personal development were mentioned. This study provides critical insights into the validity of retrospective program evaluation for assessing the long-term impact of EfS programs by introducing a cross-sectional study of different cohorts as a serial time-point sampling strategy.

Shark Conservation: An Educational Approach Based on Children's Knowledge and Perceptions toward Sharks.

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.

The model barnacle Balanus balanus Linnaeus, 1758 (Crustacea: Maxillopoda: Sessilia) mitochondrial genome and gene rearrangements within the family Balanidae.

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).
