- Testing Hopkins’ Bioclimatic Law with PhenoCam data
Specifically, we evaluated the Bioclimatic Law proposed by Hopkins, which relates phenological transitions to latitude, longitude, and elevation
- Estimating Alabama Bloom Times Using Hopkins’ Bioclimatic Law
In 1889 Andrew D Hopkins, an American entomologist, developed what is now called Hopkins’ Bioclimatic Law, an explanation of how changes in elevation, latitude, and longitude influence the timing of seasonal events in the natural world
- Global warming leads to more uniform spring phenology across . . . - PNAS
A famous American entomologist, Andrew D Hopkins, esti-mated in 1920 the progressive delay in tree leaf-out with in-creasing latitude, longitude, and elevation, a phenomenon referred to as “Hopkins bioclimatic law
- KanCRN | The Green Wave | Creating the Context | Background
The relationship is one day for every 15 minutes of latitude, 1 25 days for each degree of longitude and one day for every 30 meters of elevation It seems that in North America the further west, or north, or higher, the later spring arrives
- Bioclimatic law? - rajisperspective. com
This law was developed by an American entomologist Andrew Delmar Hopkins The law states that phenological events were shifted by four days for every 1° latitude north, 5° longitude west, and 400 ft of elevation increase (Hopkins, 1900, 1920)
- Hopkins’ Bioclimatic law | How crop phenology affected by latitude . . .
In this lecture, we have briefly discussed what is Hopkins’ Bioclimatic law and how latitude, longitude and altitude affects crop growth and phenology
- Testing Hopkins’ Bioclimatic Law with PhenoCam data
We investigated the spatial and temporal patterns of vegetation phenology with phenometrics derived from PhenoCam imagery Specifically, we evaluated the Bioclimatic Law proposed by Hopkins, which relates phenological transitions to latitude, longitude, and elevation
- Divergent phenological response to hydroclimate variability in forested . . .
This is often referred to as Hopkins’ Law which posits a 1 day delay with every 30 m increase in elevation (Hopkins, 1918), and clearly indicates the dominant controls of temperature on the onset of spring
