Range expansion of the invasive rusty crayfish Orconectes rusticus (Girard, 1852) (Decapoda: Astacoidea) in northeastern Iowa (USA) rivers [PDF]
Journal of Crustacean Biology, 2015 The rusty crayfish Orconectes rusticus (Girard, 1852) is an invasive species that has been introduced to the Upper Midwest, USA from the Ohio River Valley, and is associated with ecological damage to aquatic systems. We examined the distributions of rusty and native crayfishes in two Iowa river systems.

Zootaxa, 2020 The use of color photographs in crayfish species descriptions, state faunal books and popular articles is relatively recent. Except for verbal color descriptions, color and color patterns have not often been explored by crayfish researchers. Carotenoids and carotenoproteins are responsible for much of the color found in the integument and exoskeleton ...

Life history of the vulnerable endemic crayfish Cambarus (Erebicambarus) maculatus Hobbs and Pflieger, 1988 (Decapoda: Astacoidea: Cambaridae) in Missouri, USA [PDF]
Journal of Crustacean Biology, 2016 The vulnerable freckled crayfish, Cambarus maculatus Hobbs and Pflieger, 1988, is endemic to only one drainage in eastern Missouri, USA, which is impacted by heavy metals mining and adjacent to a rapidly-expanding urban area. We studied populations of C. maculatus in two small streams for 25 months to describe annual reproductive cycles, and gather

Life history of the coal fields crayfish Cambarus theepiensis Loughman, Foltz, Garrison and Welsh, 2013 (Decapoda: Astacoidea: Cambaridae) in southwestern West Virginia, USA [PDF]
Journal of Crustacean Biology, 2016 Data of the life history of Cambarus ( Puncticambarus ) theepiensis Loughman, Foltz, Garrison and Welsh, 2013 was collected monthly from May 2012 through April 2013 from two sites within the Twelvepole Creek watershed in southwestern West Virginia, USA. Mature females showed signs of glair development in early May.

Abundance and habitat associations of two Florida crayfishes, Procambarus paeninsulanus (Faxon, 1914) and P. fallax (Hagen, 1870) (Decapoda: Astacoidea), assessed with N-mixture modeling [PDF]
Journal of Crustacean Biology, 2018 The study of crayfishes in their native habitats is limited, even if crayfishes are economically and ecologically important. Such is the case in southeastern USA, a center of global crayfish diversity. This study investigated model-estimated abundance and habitat associations of Procambarus paeninsulanus (Faxon, 1914) and P. fallax (Hagen, 1870) in two

The hepatopancreas and ovary are the sites of vitellogenin synthesis in female red swamp crayfish (Procambarus clarkii (Girard, 1852)) (Decapoda: Astacoidea: Cambaridae) [PDF]
Journal of Crustacean Biology, 2016 Vitellogenin (Vg) is the precursor of vitellin, the major yolk protein. The site of Vg synthesis in crustaceans remains controversial. This study investigated the synthesis site of Vg in female red swamp crayfish Procambarus clarkii (Girard, 1852). Results revealed that the mRNA of Vg was detected in the tissues of hepatopancreas of P. clarkii . The
