We use near - surface cameras and field - based spectroradiometers and fluorescence spectroscopy and link ground - based measures of
phenology with imagery data obtained from satellites.

«As
phenology is advancing around the globe, there are concerns that plant - pollinator interactions may be disrupted through phenological mismatches, or mismatches in the timing of when flowers bloom and their pollinators emerge, leading to reduced plant reproduction,» says lead author Zak Gezon, who conducted the research as a doctoral student at Dartmouth and who is now a conservation biologist
with Disney's Animal Programs.
The site is also equipped
with digital cameras that are able to take automatic pictures of the ecosystem to study plant
phenology.
OU Professors Jeffrey F. Kelly, Todd Fagin and Eli S. Bridge, Oklahoma Biological Survey, and graduate student Kyle G. Horton, Department of Biology, OU College of Arts and Sciences; in collaboration
with OU Professors Phillip B. Chilson, School of Meteorology, and Kirsten de Beurs, Department of Geography and Environmental Sustainability, OU College of Atmospheric and Geographic Sciences; and Phillip M. Stepanian, formerly
with the Advanced Radar Research Center, worked together to demonstrate how migration timing relates to land surface
phenology and temperature changes.
The research team's paper, «Cerambycid beetle species
with similar pheromones are segregated by
phenology and minor pheromone components,» is featured on the cover of the May issue of the Journal of Chemical Ecology.
In addition to replacing the original maize
phenology model in CLM
with that from the APSIM model, the researchers have made several other innovative improvements in the new model.
For this work, the ITC researchers worked
with the USA National
Phenology Network (USANPN) and earlier this year they published a quality - checked phenological dataset in Scientific Data.
phenology The study of periodic biological phenomena
with relation to climate (particularly seasonal changes).
In a warming climate, the timing of activity (i.e.,
phenology) of plants and pollinators is expected to shift, but these shifts may not be synchronized
with one another (Burkle and Alarcon 2011; Burkle et al. 2013; Rafferty et al. 2013).
[Response: You fail to see that ocean temperatures, satellite measurements, glacier melting, Arctic ice retreat, changes in
phenology are all consistent
with a warming planet.
Same as
with phenology — we can't say what an individual tree or flower or bird is going to do different as climate changes.
Shows that a suite of modeled and derived measures (produced from daily maximum — minimum temperatures) linking plant development (
phenology)
with its basic climatic drivers provide a reliable and spatially extensive method for monitoring general impacts of global warming on the start of the growing season
I've been at scientific meetings in the US and Europe where highly detailed studies of range expansion and
phenology shifts are documented
with data, often
with data sets of 20 - 40 or more years.
Does it line up
with our ocean data sets, our satellite data sets, boreholes and our 100s of records of changes in species behaviour and
phenology.
We present an integrated modeling study designed to investigate changes in ecosystem level
phenology over Europe associated
with changes in climate pattern, by the North Atlantic Oscillation (NAO).
Combine the satellite trend
with the surface observations and the umpteen non-temperature based records that reflect temperature change (from glaciers to
phenology to lake freeze dates to snow - cover extent in spring & fall to sea level rise to stratospheric temps) and the evidence for recent gradual warming is, well, unequivocal.
«Our study clearly showed that European migratory bird species
with declining breeding populations in Europe in the last decades (1990 — 2000) responded the least to recent climate change as reflected by the temporal trend in spring migration
phenology, or even delayed their timing of spring migration, whereas species
with stable or increasing populations advanced migration.»
«At some point, some species likely won't be able to keep up
with earlier
phenology that warming temperatures have dictated.»
Environmental controls of
phenology of high - latitude Chinook salmon populations of the Yukon River, North America,
with application to fishery management
A synthesis of animal
phenology shows that temperature primarily drives mid-latitude responses,
with precipitation important at lower latitudes.
Thousands of species are behaving as if climate is changing — temperature, rainfall etc —
with responses such as moving to cooler regions at higher latitudes or
phenology changes (a friend of mine had a Homer «doh!
It is no surprise therefore that coastal marine species have shown some of the fastest responses to climate change in any system,
with species - specific responses to thermal stress causing poleward shifts in biogeographic distributions towards cooler environments, as well as changes in
phenology and regime shifts.
After meeting
with you and learning about Sunwest's farming approach, I am confident that my knowledge of pesticides and
phenology based treatment timing will be a great help to your team.
