Abstract

Abstract - On 2 September and 7 October 2022, we captured post-copulatory pairs of Callinectes sapidus (Blue Crab) in Green Crab traps in Great Bay Estuary, NH. On the first occasion, the 2 crabs included a mature post-ecdysis (12–24 hour) female and a mature male, and the female's shed exoskeleton also remained in the trap. Both seminal receptacles had pink sperm plugs and were turgid with spermatophores, indicative of recent successful insemination. Details of the second capture mirrored the first with the exception that the exuvia was not in the trap. This is the first scientific reporting of Blue Crabs mating in Great Bay Estuary, NH, documenting an ongoing range expansion of a species with the potential to have major ecological and economic impacts.

首次记录交配的蓝蟹，Callinectes sapidus，在大海湾河口，新罕布什尔州

摘要/ Abstract摘要:2022年9月2日和10月7日，我们在美国新罕布什尔州大湾河口(Great Bay Estuary)的绿蟹笼中捕获了交配后成对的蓝蟹(Callinectes sapidus)。第一次捕获的2只蟹包括一只蜕皮后(12-24小时)成熟的雌蟹和一只成熟的雄蟹，雌蟹的蜕皮外骨骼也保留在陷阱中。两个精囊都有粉红色的精子塞，精子囊肿胀，表明最近受精成功。第二次捕获的细节反映了第一次捕获的细节，除了蜕皮不在陷阱中。这是关于蓝蟹在新罕布什尔州大海湾河口交配的第一份科学报告，记录了一个物种的持续范围扩张，有可能产生重大的生态和经济影响。

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.
