Little did Ortmann know prevented the upstream migration of exotic crayfish that almost 100 years would pass before another into those sub-basins. systematic survey of Pennsylvania’s crayfish fauna would be undertaken. During that time, much would change across Pennsylvania but the impacts of these changes on the state’s crayfish fauna would remain unknown. Until recently, simple questions about the species in the state could not be answered. Have the ranges of the state’s native crayfishes changed since the early 1900s? Have exotic crayfishes invaded Pennsylvania? Are there any rare or threatened crayfish within the state? Fast forward to the present and the efforts of a team of scientists have begun to provide answers to these questions and others. K.

There is no indication that this species is in trade in the United States. Means of Introductions in the United States This species has not been reported as introduced or established in the United States. Remarks GBIF Secretariat (2017) refers to this species as the “Papua blue green crayfish.” 1 From Eprilurahman (2014): “Significant taxonomic disputation and confusion has surrounded the number and identity of species that is referred to as the C. quadricarinatus – C. albertisii complex, which are identifiable on the basis of red soft membraneous outer margin of the propodus of the claw. The earliest taxonomic reviewers of the genus Cherax, (Smith 1912; Calman 1911; and Clark 1936), considered there was no justification in considering C. quadricarinatus, a large freshwater crayfish, described by von Martens (1868) from northern Australia to be taxonomically distinct from C. albertisii described by Nobilli (1899) from southern New Guinea. […] In contrast, Holthuis (1949; 1950; 1982) considered C. quadricarinatus, C. albertisii and C. lorentzi to be taxonomically distinct, with the former species restricted to Australia and the later [sic] two species occurring in New Guinea. My results […] support the recognition of C.

This paper documents the first record of the blue crawfish,Cambarus monongalensis Ortmann, 1905, in the state of Ohio, United States. The blue crawfish is a small- to medium-sized primary burrowing crayfish common in western Pennsylvania and West Virginia. Because of the prevalence of this species on the east side of the Ohio River, numerous researchers have sought the blue crawfish in Ohio—to no avail. On 16 May 2020, turkey hunters in Monroe County, Ohio, located a blue-colored crayfish and sent photos to one of the authors of this study. On 19 May 2020, the authors sampled in the vicinity of where the photo was taken and located 4 sites that yielded a total of 5 blue crawfish specimens, confirming the existence of this species in Ohio. Further research is needed on the blue crawfish to determine its range and abundance in Ohio, and to explore factors relating to its biogeography.

For many childhood cancer patients, cancer treatment involves oncofertility-related discussions that involve their families, physicians, and many other people. This paper evaluates the quality of educational and clinical resources available to childhood cancer patients regarding fertility preservation and the current approach to these kinds of cases from an ethical perspective. I propose a procedure for treatment plan development and decision making that carefully considers the values and beliefs of the patient, his/her family members, physicians, and ethics board members involved with the case to help standardize the process.

The last large survey of crayfishes from West Virginia was in 1988 and 1989. In this thorough document Raymond Jezerinac, Whitney Stocker, and Donald Tarter identified three separate areas in West Virginia where non-native crayfish species have been introduced.
