A new species of Nidirana (Anura, Ranidae) from northern Guangxi, China [PDF]

ZooKeys, 2022
A new species of music frog, Nidirana guibeiensis sp. nov., is described from northern Guangxi, China. Based on two mtDNA fragments analyzed, phylogenetic trees reveal that N. guibeiensis sp. nov. is most closely related to N. leishanensis.

National Forest Inventory Contributions to Forest Biodiversity Monitoring [PDF]

Forest Science, 2012
Forests are the most biodiverse terrestrial ecosystems. National forest inventories (NFIs) are the main source of information on the status and trends of forests, but they have traditionally been designed to assess land coverage and the production value of forests rather than forest biodiversity.

Using Landsat Time-Series and LiDAR to Inform Aboveground Forest Biomass Baselines in Northern Minnesota, USA

Canadian Journal of Remote Sensing, 2017
The publicly accessible archive of Landsat imagery and increasing regional-scale LiDAR acquisitions offer an opportunity to periodically estimate aboveground forest biomass (AGB) from 1990 to the present to align with the reporting needs of National ...
