Temperature sensitivity thresholds to warming and cooling in phenophases of alpine plants

open access: yesClimatic Change, 2016
The assumption of a linear relationship between temperature and phenophases may be misleading. Furthermore, a lack of understanding of the changes in temperature sensitivity of phenophases to changes in temperature strongly limits our ability to predict phenological change in response to climate change.

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...
