Looking backwards to look forwards: the role of natural history in temperate reef ecology
No full textTemperate reefs are superb tractable systems for testing hypotheses in ecology and evolutionary biology. Accordingly there is a rich history of research stretching back over 100 years, which has made major contributions to general ecological and evolutionary theory as well as providing better understanding of how littoral systems work by linking pattern with process. A brief resumé of the history of temperate reef ecology is provided to celebrate this rich heritage. As a community, temperate reef ecologists generally do well designed experiments and test well formulated hypotheses. Increasingly large datasets are being collected, collated and subjected to complex meta-analyses and used for modelling. These datasets do not happen spontaneously – the burgeoning subject of macroecology is possible only because of the efforts of dedicated natural historians whether it be observing birds, butterflies, or barnacles. High-quality natural history and old-fashioned field craft enable surveys or experiments to be stratified (i.e. replicates are replicates and not a random bit of rock) and lead to the generation of more insightful hypotheses. Modern molecular approaches have led to the discovery of cryptic species and provided phylogeographical insights, but natural history is still required to identify species in the field. We advocate a blend of modern approaches with old school skills and a fondness for temperate reefs in all their splendour
Two new species of sand-bubbler crabs, Scopimera, from North China and the Philippines (Crustacea: Decapoda: Dotillidae)
No full textTwo undescribed species of Scopimera are herein described. Scopimera sheni sp. nov. from Qingdao, represents the fourth species of the genus to be recognized from North China. Scopimera philippinensis sp. nov. is the first record of the genus from the Philippines. Morphologically both new species belong to the "normal form" Scopimera (sensu Kemp 1919). Amongst other characters, each can be distinguished by its diagnostic male first gonopod. Mitochondrial cytochrome oxidase I (COI) gene sequences showed two distinct clades. An East Asia group (Chinese coasts, Japan, Korea and Taiwan) consisting of S. globosa De Haan, 1835, S. ryukyuensis Wong, Chan et Shih, 2010, S. sheni sp. nov., S. longidactyla Shen, 1932 and S. curtelsona (= S. cutelsoma) Shen, 1936; and a Southeast Asia group consisting of the closely related S. philippinensis sp. nov. and S. intermedia Balss, 1934. A dichotomous key is provided for all "normal forms" of Scopimera species

A distributed learning model for Freshwater Ecology Practical Classes
No full textThis paper describes a case study where a distributed learning model was used to enhance the traditional teaching of a freshwater ecology practical class by providing students with a student-centred constructivist environment. Prior to the practical session, a website was created and students were encouraged to think about the morphological adaptations of stream organisms. They were then divided into groups and taken to a real stream to collect specimens and bring them back to the laboratory for further examination and discussion. After the practical, each student group was required to produce a web page concerning the adaptations of the stream organisms, to answer a set of online tutorial questions, and to participate in web-based discussion. Feedback by questionnaire showed that the great majority of students enjoyed working with the website and found the content very useful. More than half of the students preferred this type of web-assisted, student-centred practical to conventional practicals, while about a third showed no special preference between the two approaches
