“…The present study also provides a foundation to further develop community models with multiple activity cycles. Adaptive temporal niche shifts through phenotypic plasticity or evolution 44,45 , which can change patterns of multiple activity cycles, are a key element for the application of the present theory to a more general one.…”

The current ecological understanding still does not fully explain how biodiversity is maintained. One strategy to address this issue is to contrast theoretical prediction with real competitive communities where diverse species share limited resources. I present, in this study, a new competitive coexistence theory-diversity of biological rhythms. I show that diversity in activity cycles plays a key role in coexistence of competing species, using a two predator-one prey system with diel, monthly, and annual cycles for predator foraging. Competitive exclusion always occurs without activity cycles. Activity cycles do, however, allow for coexistence. Furthermore, each activity cycle plays a different role in coexistence, and coupling of activity cycles can synergistically broaden the coexistence region. Thus, with all activity cycles, the coexistence region is maximal. The present results suggest that polyrhythmic changes in biological activity in response to the earth’s rotation and revolution are key to competitive coexistence. Also, temporal niche shifts caused by environmental changes can easily eliminate competitive coexistence.

“…For 46 years, Divoky, of Cooper Island Arctic Research, has studied a colony of black guillemots on the island. As the planet warms, he's tracking these seabirds as they lay eggs progressively earlier (2) and their colony size and breeding success decline as a result of the loss of ice-associated prey (3). "The real long-term nature of his dataset I think is remarkable," says Coryell-Martin, who's based in Port Townsend, WA.…”

Patrick Kikut watched as the 18-foot raft carrying his supplies down the Green and Colorado Rivers headed into white water. Then the raft flipped. The walls of Utah's Cataract Canyon rose above him; his belongings, strapped to the capsized raft, bobbed along in the river before him. Seated in a nearby raft, Kikut was most concerned about the dry box containing his watercolor paints and compositions. "If water gets in there," he recalls worrying, "all of the watercolors in all the little tins are going to bleed out and I'll have tie-dye."Kikut, a painter and lecturer at the University of Wyoming in Laramie, was on the Sesquicentennial Colorado River Exploring Expedition (SCREE), a 70-day, 1,000-mile journey. It was summer 2019, and the expedition marked the 150th anniversary of geologist John Wesley Powell's first passage down the Green and Colorado Rivers. Paleoecologist Thomas Minckley of the University of Wyoming organized the trip and invited researchers, conservationists, writers, and artists along.As lead artist and one of the few adventurers making the entire journey, Kikut was following in a centuries-old tradition of painters joining researchers on expeditions. Starting in the 1700s, artists became "crucially important members of scientific expeditions," says Daniela Bleichmar, a professor of history and art history at the University of Southern California in Los Angeles. Researchers relied on painters to depict plants and animals as they studied new species and, in the following centuries, sweeping landscapes as they explored new terrain.Today, the painter is no longer essential personnel on every expedition. Yet painters continue to join researchers in the field, whether through individual partnerships or artist-in-residence programs, acting as storytellers more than data collectors. The painters have artistic freedom, sometimes even shifting into the abstract. It's a role that requires not only recording but also interpreting complex, changing phenomena as well as raising awareness via media that may attract more public attention than research reports and statistics. An Evolving RoleEarly expedition painters were important players in the quest to classify species. "What CRISPR is today, the thing that everyone is excited about, taxonomy was in the 18th century," says Bleichmar. Because no single researcher could classify all living things, Expedition painter Maria Coryell-Martin hopes that her work helps audiences empathize with the plight of animals and ecosystems in the changing Arctic. In Cooper Island Pond (2019, field watercolor), Arctic light shines on black guillemots, whose population is being decimated by climate change. Image credit: Maria Coryell-Martin (artist).

“…In this issue of Functional Ecology , Sauve, Divoky, and Friesen () explore these issues in a high Arctic seabird, Mandt's black guillemot ( Cepphus grylle mandtii ), whose ecology is closely tied with sea ice. The Arctic is among the fastest warming regions globally, with concomitant rapid changes in spring phenology (Berteaux, Réale, McAdam, & Boutin, ).…”

“…Using individual‐level data, Sauve et al () showed that earlier‐breeding females fledged more chicks annually and were themselves more likely to survive to the next year. This directional selection on breeding date implies population‐level maladaptation: higher mean fitness would result if the birds bred earlier, suggesting they are lagging behind an optimum.…”

“…Overall, the Sauve et al () study represents a significant advance in understanding adaptive plasticity and constraints on adaptation in extreme environments, but important questions remain. As emphasized by these authors, future work must link trait dynamics to demography, for example whether changes in phenology or selection patterns are associated with changes in mean (age‐specific) fecundity or viability, to assess the potential consequences of future warming for population persistence.…”
