Recent climate warming has shifted the timing of spring and autumn vegetation phenological events in the temperate and boreal forest ecosystems of Europe. In many areas spring phenological events start earlier and autumn events switch between earlier and later onset. Consequently, the length of growing season in mid and high latitudes of European forest is extended. However, the lagged effects ...

The PhD research exposed in this paper aims to develop workflows for fine scale study of climate change and its impact on agriculture using volunteered geographic information in phenology. First, a consistency checking workflow was developed to ensure the quality of volunteered observations. Next, by using novel predictors, spatio-temporal variation in plant phenology is modeled so that we can ...

BACKGROUND The impacts of climate change on phenological responses of species and communities are well-documented; however, many such studies are correlational and so less effective at assessing the causal links between changes in climate and changes in phenology. Using grasshopper communities found along an elevational gradient, we present an ideal system along the Front Range of Colorado USA ...

Climate change has the potential to alter the phenological synchrony between interacting mutualists, such as plants and their pollinators. However, high levels of biodiversity might buffer the negative effects of species-specific phenological shifts and maintain synchrony at the community level, as predicted by the biodiversity insurance hypothesis. Here, we explore how biodiversity might enhan...

This study introduces a new geographic framework, phenological classification, for the conterminous United States based on Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) time-series data and a digital elevation model. The resulting pheno-class map is comprised of 40 phenoclasses, each having unique phenological and topographic characteristics...

The article presents the results of bioecological characteristics and phenological features some varieties Abelmoschus esculentus (L.) Moench in Vinnytsia region: two Ukrainian origin - ‘Sopilka’ ‘Alabama red’, as well a variety okra Turkish ‘Sultani’. Germination energy seed germination were studied. observations are obtained: calendar terms beginning phases, duration phases interphase periods...

Time series (2003 to 2007) MERIS Terrestrial Chlorophyll Index (MTCI) products were used to predict the phenology of different forest types in India. The MTCI data were corrected for noise using a temporal moving window filter and then a Fourierbased smoothing was applied without compromising annual phenological cycle. Finally, the phenological variables i.e. onset of greenness and end of senes...
