Plants are the foundation of the food web and therefore interact directly and indirectly with
myriad organisms at higher trophic levels. They directly provide nourishment to mutualistic …

Ecological interactions between crops and wild animals frequently result in increases or
declines in crop yield. Yet, positive and negative interactions have mostly been treated …

Introduced species have the potential to impact processes central to the organization of
ecological communities. Although hundreds of nonnative plant species have naturalized in …

Warm temperatures are required for insect flight. Consequently, warming could benefit many
high‐latitude and high‐altitude insects by increasing opportunities for foraging or …

Climate warming is altering the timing and distribution of primary production across the
globe and threatening the integrity of trophic systems that are highly adapted to seasonal …

Ecologists have put forth several mechanisms to predict the strength of predator effects on
producers (a trophic cascade). We suggest a novel mechanism–in systems in which …

Providing supplementary food for wild birds is a globally popular pastime; almost half of the
