Coarse-Resolution Satellite Images Overestimate Urbanization Effects on Vegetation Spring Phenology

open access: yesRemote Sensing, 2020
Numerous investigations of urbanization effects on vegetation spring phenology using satellite images have reached a consensus that vegetation spring phenology in urban areas occurs earlier than in surrounding rural areas.

A global reanalysis of vegetation phenology [PDF]

open access: yesJournal of Geophysical Research, 2011
[1] Simulations of the global water and carbon cycle are sensitive to the model representation of vegetation phenology. Current phenology models are empirical, and few predict both phenological timing and leaf state. Our previous study demonstrated how satellite data assimilation employing an Ensemble Kalman Filter yields realistic phenological model ...

Spatial-Temporal Relationship Analysis of Vegetation Phenology and Meteorological Parameters in an Agro-Pasture Ecotone in China

open access: yesRemote Sensing, 2022
Vegetation phenology is a sensitive indicator of climate change, and can help understand the response of vegetation cycles to climate, which is important for understanding the impact of global climate change on terrestrial ecosystems.

Detecting and predicting spatial and interannual patterns of temperate forest springtime phenology in the eastern U.S. [PDF]

open access: yes, 2002
We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993.

Remote sensing phenology of two Chinese northern Sphagnum bogs under climate drivers during 2001 and 2018

open access: yesEcological Indicators, 2021
Boreal peatlands, of which Sphagnum bogs are one of the main types, play essential roles in the terrestrial soil carbon pool. Vegetation phenology is a sensitive indicator that reveals the underlying processes as well as responses to climate change ...

Impacts of Urbanization on Vegetation Phenology over the Past Three Decades in Shanghai, China

open access: yesRemote Sensing, 2017
Vegetation phenology manifests the rhythm of annual plant life activities. It has been extensively studied in natural ecosystems. However, major knowledge gaps still exist in understanding the impacts of urbanization on vegetation phenology.

Vegetation Phenological Changes in Multiple Landforms and Responses to Climate Change

open access: yesISPRS International Journal of Geo-Information, 2020
Vegetation phenology is highly sensitive to climate change, and the phenological responses of vegetation to climate factors vary over time and space. Research on the vegetation phenology in different climatic regimes will help clarify the key factors ...

Variation in Detecting \u3ci\u3eSchinia Indiana\u3c/i\u3e and \u3ci\u3eSchinia Lucens\u3c/i\u3e (Lepidoptera: Noctuidae) in Wisconsin [PDF]

open access: yes, 2018
Schinia indiana (Smith) and Schinia lucens (Morrison) (Lepidoptera: Noctuidae) are diurnal moths and are well camouflaged when perched on flowers of their larval food plants: Phlox pilosa L. (Polemoniaceae) and Amorpha(Fabaceae), respectively.
