Intertidal Green Crab Survey Over a Ten-Year Period on a Maine Cobble Beach
Abstract - Here we report on the long-term monitoring of Carcinus maenas (European Green Crab) populations on an intertidal region of a cobble beach in Maine conducted from 2011 to 2021. The number of Green Crabs collected fluctuated between 129 and 474 individuals per sample event. We collected crabs twice each year, with a total number collected of 389 to 798 per year. In addition, we collected Hemigrapsus sanguineus (Asian Shore Crab) in 2 sample years (2019 and 2021), accounting for only 7 individuals. No compelling relationships between Green Crab densities and sea-water temperature, average carapace width, or year of the collection were revealed.
期刊介绍：
The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
