The Effects of Human Presence, Restraint, and Stressed Neighbors on Corticosterone Levels in Domesticated Budgerigars (Melopsittacus undulatus)

Zoo Biology, EarlyView.
Female budgerigars (Melopsittacus undulatus) did not significantly elevate their plasma corticosterone levels in response to human presence at the beginning of the experiment. However, plasma corticosterone was significantly elevated by restraint stress, the return of a neighbor that received restraint stress, and human presence at the end of the ...

The performance of growing degree day models to predict spring phenology of herbaceous species depends on the species' temporal niche

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally to the accumulated temperature. Two species‐specific parameters, TBase and t0 (minimum temperature above which and start date

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...
