February's Cover displays The West Fork Gila River, New Mexico, USA, home to Catostomus insignis, the Sonora Sucker, which acts as an ecosystem engineer by digging depressions in soft sediment areas and resuspending sediments through its primarily cryptic nocturnal feeding activities in shallow habitats. The divots transform soft sediments into a honeycomb of plateaus and depressions, capture organic matter, and are rapidly colonized by different macroinvertebrate taxa than and at a higher biomass than the surrounding sediment. Read the paper: "Consumer movement dynamics as hidden drivers of stream habitat structure: suckers as ecosystem engineers on the night shift" by Booth et al (2019).
