Integrative Conservation, EarlyView.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 ...

Diverse Responses of Vegetation Dynamics to Snow Cover Phenology over the Boreal Region [PDF]
Forests, 2019 Snow cover phenology plays an important role in vegetation dynamics over the boreal region, but the observed evidence of this interaction is limited. A comprehensive understanding of the changes in vegetation dynamics and snow cover phenology as well as the interactions between them is urgently needed. To investigate this, we calculated two indicators,

International Journal of Climatology, EarlyView.The ability to predict climate fluctuations at seasonal timescales offers significant socio‐economic benefits. However, limited understanding of predictability mechanisms and model errors hinders forecast quality. Recent research has improved forecasting systems and data quality.

Hidden Markov Quantile Models With Trends for Analysing Air Temperature Data
International Journal of Climatology, EarlyView.There is the question of whether climate change, expressed by time‐trends in temperature, is of a heterogeneous nature or not. Here, the time‐trend heterogeneity argument has been investigated using Hidden Markov (HM) quantile time‐trends models in temperature time series.
