The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry
Astronomische Nachrichten, EarlyView.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019.

Ecography, EarlyView.Insects are the most diverse terrestrial organisms, yet they are underrepresented in large‐scale conservation assessments. To address this gap, the California Insect Barcoding Initiative is developing a publicly accessible, statewide DNA‐barcode reference library for California insects to support scalable surveys, establish baseline biodiversity ...

Remote Sensing in Ecology and Conservation, EarlyView.We propose a set of paradigms (survey design, tip and cue, validation, consilience, interpolation and extrapolation, and data fusion) and prioritize a set of principles (metadata standards, use rights and licensing, scientific rigor, and utility) as the foundations of an actionable framework for nature technology data integration. We then analyze seven
