Responses of spring phenology to climate change [PDF]

New Phytologist, 2004
SummaryClimate change effects on seasonal activity in terrestrial ecosystems are significant and well documented, especially in the middle and higher latitudes. Temperature is a main driver of many plant developmental processes, and in many cases higher temperatures have been shown to speed up plant development and lead to earlier switching to the next

Time to budbreak is not enough: cold hardiness evaluation is necessary in dormancy and spring phenology studies

bioRxiv, 2022
Dormancy of buds is an important phase in the life cycle of perennial plants growing in environments where unsuitable growth conditions occur seasonally.

Timing of Karner Blue (Lepidoptera: Lycaenidae) Larvae in Spring and Adults in Spring and Summer in Wisconsin During 1991-1998 [PDF]

, 2018
During 1991-1998, formal surveys and incidental observations of the Karner blue (Lycaeides melissa samuelis) (Lepidoptera: Lycaenidae) occurred on 2-8 dates each year for spring larvae and on 5-10 dates in each adult generation at 148 pine-oak barrens in

Phenology of Spring Barley. [PDF]

Kvasny Prumysl, 2007
Phenology is the branch of science that studies mutual relationship between climate and weather and between every year repeated development of living organisms that pass through clearly defined stages, called phenological phases. In territory of Czech Republic phenological observations have long tradition.

Precipitation Dominates the Relative Contributions of Climate Factors to Grasslands Spring Phenology on the Tibetan Plateau

Remote Sensing, 2022
Temperature and precipitation are the primary regulators of vegetation phenology in temperate zones. However, the relative contributions of each factor and their underlying combined effect on vegetation phenology are much less clear, especially for the ...

No Consistent Evidence for Advancing or Delaying Trends in Spring Phenology on the Tibetan Plateau [PDF]

, 2017
Vegetation phenology is a sensitive indicator of climate change and has significant effects on the exchange of carbon, water, and energy between the terrestrial biosphere and the atmosphere.

Climate warming increases spring phenological differences among temperate trees [PDF]

Global Change Biology, 2020
AbstractClimate warming has substantially advanced spring leaf flushing, but winter chilling and photoperiod co‐determine the leaf flushing process in ways that vary among species. As a result, the interspecific differences in spring phenology (IDSP) are expected to change with climate warming, which may, in turn, induce negative or positive ecological

Improving the accuracy of spring phenology detection by optimally smoothing satellite vegetation index time series based on local cloud frequency

, 2021
Vegetation phenology can be extracted from vegetation index (VI) time series of satellite data. The maximum value composite (MVC) procedure and smoothing filters have been conventionally used as standard methods to exclude noises in the VI time series ...

Near-surface remote sensing of spatial and temporal variation in canopy phenology [PDF]

, 2009
There is a need to document how plant phenology is responding to global change factors, particularly warming trends. “Near-surface” remote sensing, using radiometric instruments or imaging sensors, has great potential to improve phenological monitoring ...

Wildflower phenological escape differs by continent and spring temperature

Nature Communications, 2022
AbstractTemperate understory plant species are at risk from climate change and anthropogenic threats that include increased deer herbivory, habitat loss, pollinator declines and mismatch, and nutrient pollution. Recent work suggests that spring ephemeral wildflowers may be at additional risk due to phenological mismatch with deciduous canopy trees. The
