Vegetation phenology is an important indicator of vegetation dynamics. The boreal forest ecosystem the main part terrestrial in Northern Hemisphere and plays role global carbon balance. In this study, dynamic threshold method combined with ground-based observation data was applied to extract phenological parameters from MODIS NDVI time-series. Then, spatiotemporal variation discussed relationship between change climatic factors concluded northeast China 2011 2020. results indicated that distribution optimal extraction has spatial heterogeneity, changing rate 3% 2% 1° increase latitude for SOS (the start growing season) EOS end season). This research also notes had advanced trend at a 0.29 d/a while delayed by 0.47 d/a. varied different types. We found preseason temperature played major effecting phenology. winter previous year significant effect on current year. Temperature autumn EOS.

Due to the complex coupling between phenology and climatic factors, influence mechanism of climate, especially preseason temperature precipitation, on vegetation is still unclear. In present study, we explored long-term trends phenological parameters different types in China north 30°N from 1982 2014 their comprehensive responses precipitation. Simultaneously, annual double-season stages were considered. Results show that satellite-based data corresponding with ground-based data. Our analyses confirmed has a strong controlling effect phenology. The start date growing season (SOS) had significant advanced trend for 13.5% study area, end (EOS) showed delayed 23.1% area. impact precipitation EOS was overall stronger than SOS, responses. Compared other types, SOS crops greatly affected by human activities while less impact. This will help us make scientific decision tackle global climate change regulate ecological engineering.

Forest ecosystems in an ecotone and their dynamics to climate change are growing ecological environmental concerns. Phenology is one of the most critical biological indicators impacts on forest dynamics. In this study, we estimated visualized spatiotemporal patterns phenology from 2001 2017 Qinling Mountains (QMs) based enhanced vegetation index (EVI) MODerate-resolution Imaging Spectroradiometer (MODIS). We further analyzed data reveal topography start season (SOS), end (EOS), length (LOS). Our results showed that metrics were very sensitive changes elevation, with a 2.4 days delayed SOS, 1.4 advanced EOS, 3.8 shortened LOS for every 100 m increase altitude. During study period, average, SOS by 0.13 year−1, EOS was 0.22 increased 0.35 day year−1. The phenological speed across different elevation not consistent. elevation-induced slightly shift reached maximum value 1500 2017. sensitivity preseason temperature displays 1 °C regionally averaged would advance average 1.23 delay 0.72 days, respectively. This improved our understanding recent variability mountain ecotones explored correlation between variables context ongoing warming.

Abstract Aims Shifts in xylem phenology directly determine the forest capacity for carbon sequestration. However, a systematic understanding of spatial patterns and underpinning drivers determining cessation wood formation ( C cw ) is lacking at pan‐continental scale. Here, we addressed this knowledge gap by compiling new dataset multiple timings northern conifers. Locations Sixty‐two study sites, Northern Hemisphere (25–55° N). Time period 2003–2018 (16 years). Taxa Thirty‐three conifer species. Methods A generalized additive model was fitted to characterize latitudinal pattern . Structural equation modelling linear mixed‐effects were applied main underlying Results The followed flat S‐shaped with increasing latitude. Photoperiod dominant determinant , longer photoperiod associated an earlier Both mean growing‐season temperature total precipitation exhibited significantly positive relationships cell elongation thus across all sites. In arid regions, pre‐growing‐season had negative effect on humid positively affected temperature. onset showed coupling sites but not Early successional species sensitive hydrothermal variations during pre‐growing season. Main conclusions We reveal role conifers highlight differentiated interactive effects between seasonal climatic factors preceding phenophases among ecoregions tree These insights provide evidence reduce uncertainty prediction uptake potential consequent biophysical feedbacks forests.
