    This paper proposes a new genus, Whittenia, for a group of irregularly coiled land snail species hitherto placed in the genus Opisthostoma. Whittenia differs from congeners in Diplommatinidae based on both molecular phylogeny and shell morphology. We reassign two previously described species (Opisthostoma vermiculum and O. gittenbergeri) to Whittenia. Both species are endemic to the limestone karsts of Kinta Valley in Perak, Peninsular Malaysia

    Using Google Earth to improve the management of threatened limestone karst ecosystems in Peninsular Malaysia

    In a world of limited resources and so many species and habitats in need of protection, informed prioritization is essential. However, we cannot prioritize effectively if historical and current information regarding a particular habitat or species remains scattered. Several good platforms have been created to help users find, use and create biodiversity information. However, good platforms for sharing habitat information for threatened ecosystems are still lacking. Limestone hills are an example of threatened ecosystems that harbor unique biodiversity, but are facing intensifying anthropogenic disturbances. As limestone is a vital resource for the construction industry, it is not possible to completely halt forest degradation and quarrying in developing countries such as Malaysia, where 445 limestone hills have been recorded in the peninsula to date. As such, there is an urgent need to identify which hills must be prioritized for conservation. To make decisions based on sound science, collating spatial and biological information on limestone hills into a publicly accessible database is critical. Here, we compile Malaysia's first limestone hill GIS map for 445 limestone hills in the peninsula, based on information from geological reports and scientific literature. To assist in conservation prioritization efforts, we quantified characteristics of limestone hills in terms of size, degree of isolation, and spatial distribution patterns. We also assessed the degree of habitat disturbance in each limestone hill in terms of buffer area forest degradation and quarrying activity. These data are stored in a KMZ file and can be accessed through the Google Earth interface. Rather than being viewed as a final output containing basic limestone hill information, this database should be regarded as a foundational platform for users to collect, store, update and manipulate spatial and biological data from limestone hills to better inform decisions regarding their management

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Missing the forest for the carbon: Five familiar lessons being learned again in Malaysia

    No full text
    As nations scramble to reduce and offset their greenhouse gas emissions to achieve the goals of the Paris Climate Agreement, and corporations do the same for their own reasons, voluntary carbon markets flourish and demand for nature-based carbon credits outpaces supplies. Global attention is on countries with substantial potential to generate certifiable forest-based carbon credits. Despite nearly 30-years of experience with carbon offset projects, forest-based climate change mitigation projects of questionable quality still proliferate in Malaysia and elsewhere. Here, we assess the feasibility and sustainability of the Nature Conservation Agreement (NCA) – a recent project that includes two million hectares of protected forest in the Malaysian state of Sabah. We use this seriously flawed example to identify five key issues that forest carbon projects should not ignore: transparency, additionality, social equity, sovereignty, and complementarity. We also suggest how all five issues could be mitigated by use of a jurisdictional approach to forest carbon project development
