«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.

Phenological observations were made on both public and private lands; permission was obtained for private land when necessary.

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.

Finding evidence that the earth has warmed over the past 30 years is very easy to do, and the ice / phenological evidence supports that.

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.

The entire phenological timeline appears to be set forward by 4 to 6 weeks.

However, the latter notably depends on the specific phenological model, implying a large uncertainty in assessing the risk exposure.

Our approach consists in comparing the statistical occurrences of the last frost (day of the year) and the characteristic budburst date for nine grapevine varieties as simulated by three different phenological models.

When spring comes early, the date of the last frost often does not shift along with temperature averages and trends of animal and plant life cycle events or phenological events.

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.

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.

Phylogeny and body size are associated with the strength of phenological shifts.

However, the Beijing phenological station is located in the suburbs, far away from the city centre area, so the UHI element may be quite weak.

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.

Climate change driven advances in the date of sea ice breakup will increasingly lead to a loss of spring polar bear foraging opportunities on ringed seal pups creating a phenological trophic «mismatch.»

Several other recent studies have linked climate change to biodiversity dynamics and conservation, most of which suggesting with high confidence that impacts of climate change are already visible through species loss, phenological (life cycle events of plants and animals e.g. flowering, breeding, migration in relation to climatic conditions) shifts and changes in geographic distributions of species.
