Research applications of primary biodiversity databases in the digital age

Our world is in the midst of unprecedented change-climate shifts and sustained, widespread habitat degradation have led to dramatic declines in biodiversity rivaling historical extinction events. At the same time, new approaches to publishing and integrating previously disconnected data resources promise to help provide the evidence needed for more efficient and effective conservation and management. Stakeholders have invested considerable resources to contribute to online databases of species occurrences. However, estimates suggest that only 10% of biocollections are available in digital form. The biocollections community must therefore continue to promote digitization efforts, which in part requires demonstrating compelling applications of the data. Our overarching goal is therefore to determine trends in use of mobilized species occurrence data since 2010, as online systems have grown and now provide over one billion records. To do this, we characterized 501 papers that use openly accessible biodiversity databases. Our standardized tagging protocol was based on key topics of interest, including: database(s) used, taxa addressed, general uses of data, other data types linked to species occurrence data, and data quality issues addressed

Assessing biodiversity from space: an example from the Western Ghats, India

We demonstrate for the first time the potential use of satellite imagery to characterize areas of high and low species richness of trees in tropical forests. Our studies, conducted in the Biligiri Rangaswamy hills in the Western Ghats, India, show a high positive correlation between species richness and the Normalized Difference Vegetation Index (NDVI), which is an index of green biomass. We discuss the application of NDVI values for biodiversity assessment and monitoring, as well as for conservation planning. The NDVI is a rough measure of green biomass

Rattan species richness and population genetic structure of Calamus flagellum in North-Eastern Himalaya, India

Rattans, the climbing palms, are one of the most important non-wood forest produce supporting the livelihood of many forest dwelling communities in India. However, extensive harvest, loss of habitat and poor regeneration has resulted in dwindling of rattan populations necessitating an urgent need to conserve the existing rattan genetic resources. In this study, using GIS tools, an attempt has been made to develop species richness maps of rattans in the North-Eastern Himalaya, a mega-diversity region in India. At least four sites of extremely high species richness were identified that could be prioritized for in situ conservation. Further, using molecular tools, genetic variability was assessed in six populations of an economically important rattan, Calamus flagellum. The population that was least disturbed or harvested maintained comparatively higher levels of genetic diversity than those that were disturbed. The study, perhaps the first in the region, emphasizes the need for developing strategies for the long-term conservation of rattans in the North-Eastern Himalaya
