Shifts in the timing of spring phenology are a central feature of global change research. Long-term observations of plant phenology have been used to track vegetation responses to climate variability but are often limited to particular species and locations and may not represent synoptic patterns. S

Metals-rich soils can occur naturally or through human activity, such as mining. Plants growing in metal-rich soils often incorporate metals into their tissues; the concentration of these metals can vary among tissues within a plant, among plants of the same species, and among species. Accumulation

Nutritional stress impacts many insect species that have differing reproductive strategies and life histories, yet it is unclear how nutrient-sensing signaling pathways mediate tissue-specific responses to changes in dietary input. In Drosophila melanogaster, insulin/insulin-like growth factor (IIS)

As natural discontinuities of stream networks, beaver ponds have the potential to influence the structure and function of stream ecosystems. After declining during the extensive fur trade in North America, beaver populations have recently grown in some areas, especially montane regions. While previo
