“…As larger fruits can only be consumed by larger birds, dispersal of larger fruits might be restricted to larger islands, whereas smaller fruits – mainly consumed by smaller birds – could also reach smaller islands. Furthermore, larger birds were often observed flying over open water to more isolated islands (Schrader, Parsch, et al, 2020), thereby possibly dispersing larger fruited species better to these islands. For seed mass, however, a possible link between bird dispersal and island characteristic remains more speculative and should be the subject of future studies.…”

“…Fruit-eating birds of different body size are the main animal seed dispersers in this island system (Schrader, Parsch, et al, 2020). Large birds are able to consume larger seeds and fruits (expressed by their mass; Herrera, 1987;Wheelwright, 1985).…”

Aim: Species diversity on islands generally increases with island area. This might arise either from direct effects of island area via neutral assembly processes or from indirect effects via habitat and structural differences between islands that scale positively with island area. Here, we tested whether community-weighted functional trait means of woody plants are directly or indirectly affected by island area to elucidate how functional traits mediate the assembly on differently sized islands.Location: Twenty-eight tropical islands (25 m 2 -12,000 m 2 ) in the Raja Ampat archipelago, Indonesia.Taxon: Woody angiosperms.Methods: Studied islands had a shared geological history but differed in terms of area, habitat quality expressed by soil depth, forest structure expressed by tree basal area and degree of isolation. Traits studied were seed and fruit mass, tree height, wood density, leaf mass per area, leaf nitrogen concentration and chlorophyll content (estimated from chlorophyll-meter units) and summarised as community-weighted means (CWM) for each island. Using liner regression, we tested whether CWMs were correlated to island area and basal area and structural equation models (SEMs) to test on direct and indirect effects of island area, basal area, soil depth and isolation on trait distributions.Results: CWM of seed mass, tree height and chlorophyll content increased with both island area and basal area, whereas leaf nitrogen concentration decreased with increasing basal area. Fruit mass was not correlated to island area and basal area. SEMs revealed that the shifts in tree height, wood density, leaf nitrogen concentration and chlorophyll content were caused directly by basal area, which in turn was directly and positively affected by both island area and soil depth. Differences in seed mass among islands were explained by combined effects of basal area, island area and isolation, whereas fruit mass was only explained by isolation. Main conclusions:Trait values shifted systematically across islands of different sizes.Being small and having light seeds are prevailing trait combinations for establishing on small islands with simple forest structure.

“…Geoparks can also use social media to convey information about conservation, sustainability, and environmental protection, and educate the public, tourists, and the younger generation. Utilizing social media effectively allows Geopark to forge partnerships and collaborations with institutions, organizations, and individuals who share the same goals (Schrader et al, 2020). Overall, social media is a powerful tool to expand the reach and impact of the Raja Ampat Geopark, promote sustainability goals, and raise awareness about natural beauty and biodiversity.…”

The creation of parks as a significant endeavor to enhance the worth of tourism sites has emerged as a prominent phenomenon that garners global attention. The Raja Ampat Geopark has initiated branding efforts to position itself as an exceptionally distinctive tourism attraction in Indonesia. Collaboration amongst stakeholders is essential and cannot be disregarded. This research seeks to ascertain the branding activities involved in establishing the Raja Ampat Geopark, as well as the specific roles played by each partner, utilizing the Penta helix model and collaboration theory. The constructivist paradigm is employed to comprehend the process of knowledge generation inside the Penta helix model. The research findings indicate that successful geopark branding relies on a strong partnership between the government, universities, the tourism industry, local communities, and digital media. Integrating promotion with the preservation of nature and culture in a branding plan effectively enhances awareness and fosters a favorable perception of the Raja Ampat Geopark in a sustainable manner. While the Raja Ampat Geopark has experienced a notable increase in tourism, there are difficulties in effectively managing the balance between this growth and the preservation of the environment, which is crucial for ensuring a sustainable future. This study enhances the progress of geopark development and sustainable tourism by emphasizing the significant role of collaboration and branding based on the Penta helix model. Additional study is required to offer efficient recommendations for the establishment of parks in the future.

We introduce a new dataset of woody plants on 60 small tropical islands located in the Raja Ampat archipelago in Indonesia. The dataset includes incidence, abundance and functional trait data for 57 species. All islands were sampled using a standardised transect and plot design providing detailed information on plant occurrences at different spatial scales ranging from the local (plot and transect scale) to the island scale. In addition, the dataset includes information on key plant functional traits linked to species dispersal, resource acquisition and competitive strategies. The dataset can be used to address ecological questions connected to the species-area relationship and community assembly processes on small islands and in isolated habitats. The dataset yields detailed information on plant community structure and links incidence, abundance and functional trait data at different spatial scales. Furthermore, this is the first plant-island dataset for the Raja Ampat archipelago, a remote and poorly studied region, and provides important new information on species occurrences.
