Natural history and ecological observations of a population of Conhaway crayfishes and their symbiotic branchiobdellidan associates
… This relationship has been confirmed as a cleaning symbiosis in several species. The Conhaway crayfish, Cambarus appalachiensis, is a species of crayfish endemic to the New River Basin in Virginia and West Virginia. We studied a population of C. appalachiensis in Sinking Creek in …

Mountain Lake Revisited: Impacts of Invasion on Native Symbiotic Systems
… crayfish host diverse assemblages of obligate cleaning symbionts known as branchiobdellida. This cleaning symbiosis has been found to result in significant fitness benefits for native crayfish. Historical survey work showed that invasive crayfish, known to be intolerant of symbionts, were …

Invasive Hosts and their Context Dependent Relationships with Native Symbionts
… Branchiobdellidan worms can have a mutualistic cleaning symbiosis with crayfish, or at times become parasitic and feed on crayfish gill tissue if nutrients on the host are low. With the introduction of invasive crayfish in the Southern Appalachians in Virginia, branchiobdellidan worm populations …

Downstream Dilemma: Navigating Microplastic's Impact on Freshwater Symbiosis in the Anthropocene
… first study assessing the impact of a freshwater symbiosis, as symbioses in the scope of toxicokinetic studies have primarily been dominated by that of terrestrial and marine relationships. This knowledge gap is a serious concern as its argued freshwater systems are more contaminated, than that of …

Towards an understanding of symbiont natural history through studies of crayfish and their annelid associates
… underlying changes in the costs and benefits of symbiosis. I then show that this change in host resistance creates predictable patterns of symbiont diversity and composition throughout host ontogeny. Host resistance limits within-host symbiont communities to a few weakly interacting species, …

Predatory and Mutualistic Interactions between Freshwater Minnows and their Predators
… and provide preliminary evidence of a potential cleaning symbiotic mutualism between the turtle and minnows. I found that epizoic coverage decreases during the duration of a minnow spawning season after an initial increase with early summer warming, and my results also present unique and shared …
