Widespread mismatch between satellite observed vegetation greenness and temperature isolines during 2000–2020 in China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 147, P. 110018 - 110018

Warming is projected to increase the greenness of vegetation and lead geographic shifts in isolines across China. However, it unclear whether shift can keep pace with that temperature because activity always limited by resource availability relatively slow acclimation mechanisms. In addition, how natural anthropogenic factors affect this mismatch poorly understood. Based on remote sensing observations over last two decades (2000–2020), we systematically evaluated respond warming trends The result showed a widespread between greenness. 74 % area lag behind or move opposite direction temperature. We also found temperature-greenness strongly determined elevation, slope, type, human activity. magnitude decreased inversely slope elevation but increased when increased. mean velocity was greatest for deciduous forest (0.45 km/year), followed grass, shrubs, evergreen forest. This systematic analysis has important implications sustainable management under climate change. Our study underscored importance understanding role topography, vegetation, studying mismatch.

From eradication to conservation: identifying areas for restoration and management of a Pliocene relic in a changing climate

By 1985, approximately 400,000 ha of the keystone species Shinnery oak's ( Quercus havardii ) historic distribution had been eliminated for agricultural purposes across southwestern United States. These trends indicate a need targeted conservation and restoration efforts, especially considering increased attention received its role in providing habitat endangered fauna. Setting spatially explicit targets can be challenging with limited distributions, as change climate conditions over time may disconnect relationship between environmental suitability static, topo‐edaphic factors. Our objective was to identify areas oak explore plays determining these while relationships. We constructed ecological niche models estimate under current temporally transferred our model using an ensemble‐mean general circulation predicted retain through 2100. The best informed by one two variables. created second excluding variables future plant–climate Incorporating insights from both static (e.g. soil) dynamic climate) variables, we identified characterized persistent high soil type suitability. Lastly, incorporated data on land use ownership socio‐ecological influences management decisions. identifying agreement modeled distributions social context, prioritized where persists changing facilitate success.

Climate change is projected to alter the structure of plant communities due increasing temperatures and changes precipitation patterns, particularly in midlatitude dryland ecosystems. Modifications climatic suitability may lead major community such as altered dominant functional types. Previous studies have indicated that likely increase for C
