In rivers and lakes across North America, fish carry secrets invisible to the naked eye, secrets that researchers with the U.S. Geological Survey’s Eastern Ecological Science Center are determined to help uncover. With a passion for aquatic health and an interest in viral sleuthing, these researchers, including Dr. Clayton Raines, a fish biologist, have conducted groundbreaking research that is reshaping our understanding of fish disease. From uncovering a new virus in alewives to decoding the mystery behind the blotchy skin of black basses, this work not only expands the frontiers of fish virology but also reveals the hidden complexities of ecosystems. Here, we explore Raines’ and colleagues’ fascinating findings and their implications for fish management, conservation, and the health of freshwater species.

If you were to observe a quiet Dutch pasture, you might not guess that one of the most important climate-resilience workers in the landscape is silently engineering the soil beneath the grass. However, just below your feet, an unassuming creature plays a role in buffering floods, preserving crops during droughts, and quietly maintaining the natural plumbing system of the land. This creature is the humble deep-burrowing earthworm, Lumbricus terrestris (or L. terrestris for short). In recent years, researcher Roos van de Logt of the Louis Bolk Institute, and colleagues, have been uncovering the surprisingly complex story of this earthworm. Their findings suggest that supporting, and in some cases reintroducing, L. terrestris could be a powerful, nature-based tool for helping European grasslands adapt to intensifying climate extremes.
