“…We will pay attention to the fact that the majority of plant species are rare (Yahara & al., 2012) in terms of range size among various forms of rarity (Rabinowitz, 1981;Gaston, 1997). In the case of legume species in tropical SE Asia, 806 species (66%) among the 1220 total for which specimen records are georeferenced by the Naturalis Biodiversity Center, section National Herbarium of the Netherlands (NHN), had five or less records (Fig.…”

“…Thus, many plant species are also being lost, but it remains uncertain at what rate we are losing plant species diversity (Butchart & al., 2010;Rivers & al., 2011;Yahara & al., 2012). To reduce this uncertainty, we need to assess states and trends of as many plant species as possible at the global scale (GEO BON, 2010).…”

“…While plants support many ecosystem services such as food provisioning, mitigating floods and droughts, carbon sequestration, primary production, and cultural inspiration (Daily & al., 2000;Millennium Ecosystem Assessment, 2005), plant natural habitats such as forests and wetlands are being rapidly lost. Thus, many plant species are also being lost, but it remains uncertain at what rate we are losing plant species diversity (Butchart & al., 2010;Rivers & al., 2011;Yahara & al., 2012). To reduce this uncertainty, we need to assess states and trends of as many plant species as possible at the global scale (GEO BON, 2010).…”

While many plant species are considered threatened under anthropogenic pressure, it remains uncertain how rapidly we are losing plant species diversity. To fill this gap, we propose a Global Legume Diversity Assessment (GLDA) as the first step of a global plant diversity assessment. Here we describe the concept of GLDA and its feasibility by reviewing relevant approaches and data availability. We conclude that Fabaceae is a good proxy for overall angiosperm diversity in many habitats and that much relevant data for GLDA are available. As indicators of states, we propose comparison of species richness with phylogenetic and functional diversity to obtain an integrated picture of diversity. As indicators of trends, species loss rate and extinction risks should be assessed. Specimen records and plot data provide key resources for assessing legume diversity at a global scale, and distribution modeling based on these records provide key methods for assessing states and trends of legume diversity. GLDA has started in Asia, and we call for a truly global legume diversity assessment by wider geographic collaborations among various scientists.

“…Many natural history museums around the world have contributed to the GBIF, and there are currently approximately 500 million entries of biodiversity (occurrence) data. Several regions and countries (e.g., the Asia-Pacific region), however, have much less data than do the European Union and North America (GBIF, 2012;Yahara et al, 2012).…”

Murase, A.;Shiina, M.; Masui, R., and Senou, H., 2015. Integrating and utilizing citizen biodiversity data on the Web for science: An example of a rare triggerfish hybrid image provided by a sport fisherman.We report a photograph of the rare triggerfish hybrid, Rhinecanthus aculeatus 3 R. rectangulus (order Tetraodontiformes; family Balistidae), from Miyako-jima Island, Ryukyu Islands, southern Japan, that was provided by a sport fisherman via WEB sakana-zukan (an online photographic database of fish in Japan). The image was registered in the Fish Image Database of the Kanagawa Prefectural Museum of Natural History to make it available for scientific scrutiny. Here we emphasize the importance of communication between citizens, such as fishermen, scuba divers, and others, and experts via the Internet, to make possible the processing of biodiversity information provided by citizens into museum collections. This communication contributes Global Biodiversity Information Facility data for various biological studies, such as those on taxonomy, morphology, fauna/flora, community ecology, and biogeography.

“…This is particularly true in Southeast Asia, where lowland forests have been destroyed at higher rates than other tropical regions [3,5,13]. Although Cambodia still sustains a large area of primary lowland forest amounting to about 60% of the land [14,15], pressures for forest loss such as illegal logging have been increasing in recent years.…”

Ecological communities including tropical rainforest are rapidly changing under various disturbances caused by increasing human activities. Recently in Cambodia, illegal logging and clear-felling for agriculture have been increasing. Here, we study the effects of logging, mortality and recruitment of plot trees on phylogenetic community structure in 32 plots in Kampong Thom, Cambodia. Each plot was 0.25 ha; 28 plots were established in primary evergreen forests and four were established in secondary dry deciduous forests. Measurements were made in 1998, 2000, 2004 and 2010, and logging, recruitment and mortality of each tree were recorded. We estimated phylogeny using rbcL and matK gene sequences and quantified phylogenetic a and b diversity. Within communities, logging decreased phylogenetic diversity, and increased overall phylogenetic clustering and terminal phylogenetic evenness. Between communities, logging increased phylogenetic similarity between evergreen and deciduous plots. On the other hand, recruitment had opposite effects both within and between communities. The observed patterns can be explained by environmental homogenization under logging. Logging is biased to particular species and larger diameter at breast height, and forest patrol has been effective in decreasing logging.
