<p>In late 1969, Edward S. Deevey, Jr. delivered a talk to the National Water Commission, with the catchy title “In Defense of Mud.” The text of his speech was published the following year in the <i>Bulletin of the Ecological Society of America</i> (Deevey <span>1970</span>). The year of publication coincided with the first celebration of Earth Day and was a time of growing realization that humans were transforming the planet, thereby threatening many species with extinction. In what may have appeared to be an odd argument for conserving non-marine aquatic ecosystems, Deevey proposed that lakes, wetlands, ponds, and estuaries deserved protection, not only because they are homes for iconic birds, mammals, and fish, but because the sediments that accumulate within them are habitats for the bacteria that reduce nitrate and sulfate, making them important players in key global biogeochemical cycles. Humans were emitting tremendous amounts of sulfate and nitrate into the atmosphere. At the same time, they were ditching and draining wetlands for agriculture and construction, thus endangering the anoxic, muddy realm in which nitrate- and sulfur-reducing microbes live.

<p>Professor James A. MacMahon passed away on May 6, 2024, in Logan, Utah, having played a leading role in the science of ecology and in the Ecological Society of America. Jim was ESA's president in 1997–1998, guiding the society through difficult financial times and expanding membership through young scientist recruitments. Jim received the ESA Distinguished Service Award* in 2005 and was an ESA Elected Fellow in 2012. Jim's scientific career spanned 71 years, of which the last 53 years were spent in the Department of Biology at Utah State University, Logan. Over these many years, Jim mentored 62 graduate students and published 135 papers and books. While always professing to be “just a simple country boy,” to everyone who knew him, Jim was clearly a “Renaissance Man” in all respects and an ecologist in every sense of the word. His enormous breadth of scientific interests and knowledge was illustrated in the wide range of his studies; Jim and his students published ecological papers on snakes, turtles, lizards, frogs, salamanders, birds, rodents, large mammals, spiders, ants, beetles, grasshoppers, flies, mycorrhizal fungi, and plant communities from forests to deserts. Jim's expertise lay in the areas of disturbance ecology, succession, and ecosystem restoration (specifically animal-related disturbances, volcanic eruptions, and surface mining activities), along with the conceptual organization of ecological communities. His research addressed concepts in community assembly, animal behavior, biogeography of plants and animals, herbivory, granivory and seedling recruitment, predator–prey interactions, decomposition and nutrient cycling, and systematics and evolution.</p><p>Jim was the lead Principal Investigator on several major research projects funded by the National Science Foundation. In the 1970s, Jim and his graduate students worked on a large study of succession in the spruce–fir forests of northern Utah, USA. This was followed by a 10-year series of multidisciplinary NSF grants focused on successional processes for ecosystem restoration in shrub–steppe habitat following surface mining disturbances in Wyoming, USA. At a time when studies of succession were largely observational, Jim was leading the designing of experiments focusing on driving mechanisms at a finer resolution than previously undertaken. Sometimes, these experiments were huge, as in the case of the restoration studies undertaken involving hundreds of plantings in computer-generated patterns. In other cases, the manipulation involved a single animal interacting with a single plant and watching how that interaction played out over decades. The eruption of the Mount St. Helens volcano in 1980 provided Jim and his colleagues and students with an outdoor laboratory to examine primary and secondary successional processes that has continued for over four decades with NSF and US Forest Service support recording the post-eruption community development of plants, insects, amphibians,

COVER PHOTO: A moose (Alces alces) stands in a young Norway spruce (Picea abies) production forest. As described in Felton et al. (https://doi.org/10.1002/ecy.4377), consumption of agricultural root crops (provided as supplementary food by humans) was correlated with more browsing on and consumption of Norway spruce by moose. Moose are the largest free-ranging herbivores in the boreal forest ecosystem, and moose browsing can exert significant pressure on forests. This photo was taken by Jorgen Wiklund at a study site in Sweden, where spruce-dominated forests are common. Additional images appear in this issue of the Bulletin's Photo Gallery.
