Knowledge graph centered on NOAA weather station monitoring with 75 nodes and 225 connections. Top connected: Effects of climate change on phenology, frost dama, Marmota flaviventris, Hummingbird, Bombus, Ligusticum porteri.
Long-term systematic collection of first sighting and median activity dates for plants, insects, mammals, amphibians and birds in a high-elevation montane ecosystem. Standardized protocols track flowering times, insect emergence, mammal pup emergence, amphibian reproduction stages, and bird arrival dates.
Synthesized from method descriptions across 12 papers using this protocol.
Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Current and lagged climate affects phenology across diverse taxonomic groups (2023), Proceedings of the Royal Society B. The protocol was originally introduced by Early snowmelt projected to cause population decline in a subalpine plant (2019), PNAS. Implementations in other papers (listed below) may differ.
