The seasonal dynamics of a High Arctic plant–visitor network: temporal observations and responses to delayed snow melt
Plant–visitor food webs provide important insights into species interactions, and more information about their seasonal dynamics is vital to understanding the resilience of species to external pressures. Studies of Arctic networks can also improve our understanding of species responses to the pressu...
