Decreased Sensitivity of Grassland Spring Phenology to Temperature on the Tibetan Plateau

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Spring phenology is a critical indicator to characterize vegetation dynamics and their responses to climate change. Spring phenology on the Tibetan Plateau (TP) has received extensive attentions as it has experienced one of the most rapid warmings ...

A Spatial Perspective on the Phenological Distribution of the Spring Woodland Caterpillar Peak [PDF]

The American Naturalist, 2019
A classic system for studying trophic mismatch focuses on the timing of the spring caterpillar peak in relation to the breeding time and productivity of woodland passerine birds. Most work has been conducted in single-site oak woodlands, and little is known about how insights generalize to other woodland types or across space.

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Wavelet Analysis Reveals Phenology Mismatch between Leaf Phenology of Temperate Forest Plants and the Siberian Roe Deer Molting under Global Warming

Remote Sensing, 2022
Global warming is deeply influencing various ecological processes, especially regarding the phenological synchronization pattern between species, but more cases around the world are needed to reveal it.

Influence of spring and autumn phenological transitions on forest ecosystem productivity [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2010
We use eddy covariance measurements of net ecosystem productivity (NEP) from 21 FLUXNET sites (153 site-years of data) to investigate relationships between phenology and productivity (in terms of both NEP and gross ecosystem photosynthesis, GEP) in temperate and boreal forests.

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

Ecography, EarlyView.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

Decreasing temperature sensitivity of spring phenology decelerates the advance of spring phenology in northern temperate and boreal forests

Ecological Indicators
The start of the growing season (SOS) plays a pivotal role in the intricate interplay between climate and terrestrial ecosystems. Since the late 1990 s, a slowdown in SOS advancing trend has been documented across numerous regions in the Northern Hemisphere.

Citizen science deepens the ecological and climatic dimensions of mosquito surveillance

Ecography, EarlyView.
As mosquito‐borne diseases continue to expand worldwide, integrating citizen science into vector surveillance presents untapped potential. This study compares ecological models of Aedes albopictus, an invasive mosquito and global vector of dengue and other arboviruses, in Spain (2020–2022), using two contrasting data sources: traditional traps and ...

Comparison of Spring Phenology from Solar-Induced Chlorophyll Fluorescence, Vegetation Index, and Ground Observations in Boreal Forests

Remote Sensing
Spring phenology (start of growing season, SOS) in boreal forests plays a crucial role in the global carbon cycle. At present, more and more researchers are using solar-induced chlorophyll fluorescence (SIF) to evaluate the land surface phenology of ...
