    Latitudinal and temporal variation in injury and its impacts in the invasive Asian shore crab Hemigrapsus sanguineus
    (Nature Research, 2022-10-03) Griffen, Blaine D ; Alder, Jill ; Anderson, Lars ; Asay, Emily Gail ; Blakeslee, April ; Bolander, Mikayla ; Cabrera, Doreen ; Carver, Jade ; Crane, Laura C ; DiNuzzo, Eleanor R ; Fletcher, Laura S ; Luckett, Johanna ; Meidell, Morgan ; Pinkston, Emily ; Reese, Tanner C ; Repetto, Michele F ; Smith, Nanette ; Stancil, Carter ; Tepolt, Carolyn K ; Toscano, Benjamin J ; Vernier, Ashley
    Nonlethal injury is a pervasive stress on individual animals that can affect large portions of a population at any given time. Yet most studies examine snapshots of injury at a single place and time, making the implicit assumption that the impacts of nonlethal injury are constant. We sampled Asian shore crabsHemigrapsus sanguineusthroughout their invasive North American range and from the spring through fall of 2020. We then documented the prevalence of limb loss over this space and time. We further examined the impacts of limb loss and limb regeneration on food consumption, growth, reproduction, and energy storage. We show that injury differed substantially across sites and was most common towards the southern part of their invaded range on the East Coast of North America. Injury also varied idiosyncratically across sites and through time. It also had strong impacts on individuals via reduced growth and reproduction, despite increased food consumption in injured crabs. Given the high prevalence of nonlethal injury in this species, these negative impacts of injury on individual animals likely scale up to influence population level processes (e.g., population growth), and may be one factor acting against the widespread success of this invader.

    Effects of season and latitude on the diet quality of the invasive Asian shore crab Hemigrapsus sanguineus
    (Inter Research, 2023-01-26) Reese, Tanner C. ; Alder, Jill ; Asay, Emily Gail ; Blakeslee, April M.

    Invasive species alter invaded ecosystems via direct impacts such as consumption. In turn, an invasive species’ ability to thrive in new habitats depends on its ability to exploit available resources, which may change over time and space. Diet quality and quantity are indicators of a consumer’s consumptive effects and can be strongly influenced by season and latitude. We examined the effects of season and latitude on the diet quality and quantity of the invasive Asian shore crab Hemigrapsus sanguineus throughout a non-winter sampling year at 5 different sites spanning 8° of latitude across its invaded United States range. We found that diet quality, averaged through time, largely follows an expected latitudinal cline, being higher in the center of its range and lower toward the southern and northern edges. We also found that while some sites show similar patterns of diet quality variation with season, no pattern is consistent across all latitudes. Finally, we found that crabs at sites with low diet quality during summer reproductive months did not compensate by increasing total consumption. Because the Asian shore crab is an important consumer in its invaded ecosystems, understanding how its diet quality and quantity vary with season and latitude can help us better understand how this species influences trophic interactions and community structure, how it has been able to establish across a wide ecological and environmental range, and where future range expansion is most likely to occur.

    This dataset includes behavioral observations of individual mangrove tree crabs, Aratus pisonii: the proportion of time spent sitting, moving, feeding, or not visible. Size and sex of the crabs, water temperature, and tidal period of the observations were also recorded. Crabs were collected near Fort Pierce, Florida from a dock area and released into one of three habitats: mangrove, saltmarsh or under the dock.
