Abstract
Racemobambos ceramica S.Dransf. (Poaceae, Bambusoideae), an endemic bamboo species from Seram Island, Indonesia, was first described in 1980. The description was based on a single specimen (Rutten 2234) collected in 1919 from Makina, deposited at Herbarium Bogoriense (BO). The protologue lacked details on the shoot, culm and culm leaf morphology. A 2024 rediscovery of R. ceramica at Manusela National Park, Seram Island, has expanded its known distribution beyond the original locality, marking its rediscovery after 105 years. This rediscovery offers a chance to refine the morphological description and evaluate its conservation status. It also provides data to predict habitat suitability and then forecast the distribution of R. ceramica on Seram Island. This study aimed to revise the taxonomic description of R. ceramica, assess its conservation status, and identify potential habitats across Seram Island. Research was conducted through field surveys on Seram Island and the analysis of herbarium specimens. Based on these findings, we provided a more detailed morphological description of R. ceramica. A preliminary assessment classifies R. ceramica as Near Threatened (NT) on the IUCN Red List of Threatened Species. The habitat of R. ceramica is best suited to karst hill and mountain complexes, thriving on sloped terrain above 1000 m in forested areas. Our model predicts that R. ceramica habitat suitability is highest in the Manusela National Park highlands, especially around Mount Binaiya, spanning Seram Utara to northwestern Telutih, and in western (Taniwel and Taniwel Timur) and southern (Tehoru) Seram.
期刊介绍:
The Journal for Nature Conservation addresses concepts, methods and techniques for nature conservation. This international and interdisciplinary journal encourages collaboration between scientists and practitioners, including the integration of biodiversity issues with social and economic concepts. Therefore, conceptual, technical and methodological papers, as well as reviews, research papers, and short communications are welcomed from a wide range of disciplines, including theoretical ecology, landscape ecology, restoration ecology, ecological modelling, and others, provided that there is a clear connection and immediate relevance to nature conservation.
Manuscripts without any immediate conservation context, such as inventories, distribution modelling, genetic studies, animal behaviour, plant physiology, will not be considered for this journal; though such data may be useful for conservationists and managers in the future, this is outside of the current scope of the journal.
