Sentences with phrase «of phenological»

Of course there is the melting ice, but also the vast empirical evidence of phenological changes.

In contrast to a number of phenological studies showing nonlinear relationships between phenology and temperature, due largely to unmet chilling and photoperiod requirements, our findings demonstrate the relationship to be linear and to explain most of the variation in flowering.

The paper represents a «critical synthesis of the existing scientific support for the patterns, mechanisms, and consequences of phenological changes in bird migration,» according to the study.

«I would like to see a network of phenological data — such as bloom dates of particular plants — that could be tracked in real time worldwide,» NOAA's Peterson says.

«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.

These results suggest that first flowering date, the most commonly collected phenological metric in plants, is not necessarily an accurate estimator of total responses to a changing climate.

As well as aiming to learn more about the phenological response of the U.K.'s orchids to environmental change, researchers hope this project will add to their understanding of U.K. orchid distribution and population health more widely.

Climate change, phenology, and phenological control of vegetation feedbacks to the climate system.

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

Given the level of denialism in the face of glacial mass loss, plummeting Arctic summer ice cover, progressive collapse of ice shelves that have been stable for 6000 to 10000 years, northward, upward, and seasonally earlier movements of ecosystems and other phenological changes, increasing Greenland ice melt, and all the other direct observations of global warming, I think denialists will go to their graves believing it can't be happening.

Overall, we identified Alsace, Burgundy and Champagne as the most vulnerable regions, where the probability of tardive frost is projected to significantly increase throughout the 21st century for two out of three phenological models.

Such phenological plasticity among key secondary producers like zooplankton may thus narrow the risks of extreme mismatch between primary production and secondary production in an increasingly variable arctic environment.

The UHI effect is real enough, but it is corrected for — and in any case can not effect ocean temperatures, retreating glaciers or phenological changes (all of which confirm significant warming).

Because poor simulation of meteorological variables is common in climate models, a determination that meteorological variability is more important for certain variables than leaf variability may point to meteorological bias correction as a more fruitful development path — for certain model applications — than the development of a dynamic phenological routine.

Climate - induced change in biotic interactions, such as loss of mutualist partner species, increases in disease or pest incidence, phenological mismatches, or trophic cascades through food webs after decline of a keystone species.

To quantify the contribution of the UHI effect to phenological variation is therefore another hot topic for the future in the field of phenology.»

In fact, from the validation I have seen and the difference with «naive» 1D models or purely phenological extrapolations / fits, you will have to argue a lot before I accept to let them go out of «experimental».

At present, there are few phenological observation sites in other suburbs of Beijing, and so the relative contribution to phenological advancement by natural climate warming and the UHI effect could not be distinguished clearly.
