Without these species, the ecosystem would be radically altered or even collapse. This pocket-sized field guide by bestselling naturalist Collin Varner highlights 50 keystone birds, mammals, amphibians, insects,
in rocky intertidal ecosystems in the Pacific Northwest. One of his study sites, located at Mukkaw Bay, contained a community consistently dominated by the same species of mussels, barnacles, and the starfish,Pisaster ochraceus, which preys upon the other species as a top predator (Figure 1)....

Changing to 5- or 1-year timesteps would have vastly increased our processing time, reducing our ability to run the required number of scenarios and iterations of each scenario. Regeneration was simulated using species-specific seed dispersal kernels and establishment probabilities which are based on...
Salmon are a keystone species. They play a vital role in ecosystem health, feeding the likes of bears and wolves and even the forest as scraps left by predators at the base of trees decompose and enrich the soil. The Wedzi...
Forests are essential for maintaining species diversity, stabilizing local and global climate, and providing ecosystem services. Exploring the impact of paleogeographic events and climate change on the genetic structure and distribution dynamics of fores

Furthermore, given the relative increase in frequency and intensity of freshwater incursions in the Pacific Northwest and the intolerance of P. ochraceus to lowered salinity, there is the long-term potential to significantly alter patterns of species zonation in this essential marine habitat....
