Evolution, Volume 71, Issue 10, Page 2522-2532, October 2017., 2017 Abstract Caves are perceived as isolated, extreme habitats with a uniquely specialized biota, which long ago led to the idea that caves are “evolutionary dead‐ends.” This implies that cave‐adapted taxa may be doomed for extinction before they can diversify or transition to a more stable state.

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

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.

Appendage regeneration after autotomy is mediated by Baboon in the crayfish Procambarus fallax f. virginalis Martin, Dorn, Kawai, Heiden and Scholtz, 2010 (Decapoda: Astacoidea: Cambaridae) [PDF]
Journal of Crustacean Biology, 2016 Autotomy is an adaptive response in which animals escape from predators by shedding their own appendages. It is made possible by the presence of an efficient mechanism for regeneration. Decapod crustaceans frequently exhibit excellent abilities to regenerate complete pereopods in just a few molts following autotomy.
