1 We Thank the Referees for Their Careful Review
We thank the referees for their careful review and thoughtful comments. Below please see our point-by-point responses and changes made to the manuscript. Referee report #1 Thank you for responding to my comments. It is now clearer what is going on, but some additional enhancements are desirable. You need to state clearly in the abstract and probably in the manuscript as well that you are using pre-industrial conditions to examine sea-ice generated Antarctic precipitation variability in the absence of anthropogenic forcing. This should appear explicitly in the first sentence of the abstract, I think, rather than being implicit here and throughout the manuscript. I am recommending minor revisions, but think that this is a very important aspect to address comprehensively to make the intent and methodology of your extensive work obvious to the reader. Done as suggested. Now the first sentence of the abstract reads “We conduct sensitivity experiments using a general circulation model that has an explicit water source tagging capability forced by prescribed composites of pre-industrial sea ice concentrations (SIC) and corresponding sea surface temperatures (SST) to understand the impact of sea ice anomalies on regional evaporation, moisture transport, and source–receptor relationships for Antarctic precipitation in the absence of anthropogenic forcing.” A similar statement is also made in the summary paragraph of the Introduction section: “In this study, we aim to understand the impact of SO sea ice anomalies associated with internal variability (in the absence of anthropogenic forcing) on local evaporation, moisture transport and source–receptor relationships for moisture and precipitation over Antarctica using a GCM that has an explicit water source tagging capability.” Section 3.2: You attribute southerly katabatic flow to the polar high. -

Fleas (Siphonaptera) Infesting Giant Kangaroo Rats (Dipodomys Ingens) on the Elkhorn and Carrizo Plains, San Luis Obispo County, California
SHORT COMMUNICATION Fleas (Siphonaptera) Infesting Giant Kangaroo Rats (Dipodomys ingens) on the Elkhorn and Carrizo Plains, San Luis Obispo County, California STEPHEN P. TABOR/ DANIEL F. WILLIAMS,2 DAVID}. GERMAN0,2 3 AND REX E. THOMAS J. Med. Entomol. 30(1): 291-294 (1993) ABSTRACT The giant kangaroo rat, Dipodomys ingens (Merriam), has a limited distri bution in the San Joaquin Valley, CA. Because of reductions in its geographic range, largely resulting from humans, the species was listed as an endangered species in 1980 by the California Fish and Game Commission. As part of a study of the community ecology of southern California endangered species, including D. ingens, we were able to make flea collections from the rats when they were trapped and marked for population studies. All but one of the fleas collected from the D. ingens in this study were Hoplopsyllus anomalus, a flea normally associated with ground squirrels (Sciuridae). It has been suggested that giant kangaroo rats fill the ground squirrel niche within their range. Our data indicate that this role includes a normal association with Hoplopsyllus anomalus. KEY WORDS Dipodomys ingens, Hoplopsyllus anomalus, population studies THE GIANT KANGAROO RAT, Dipodomys ingens the only flea known from D. ingens.

Translocating Endangered Kangaroo Rats in the San Joaquin Valley of California: Recommendations for Future Efforts

TENNANT*, DAVID J. GERMANO, AND BRIAN L.

Box 9622, Bakersfield, CA 93389 USA (BLC) Present address of ENT: Central Region Lands Unit, California Department of Fish and Wildlife, 1234 E. Shaw Ave. Fresno, CA 93710 USA *Correspondent: [email protected] Since the early 1990s, translocation has been advocated as a means of mitigating impacts to endangered kangaroo rats from development activities in the San Joaquin Valley. The factors affecting translocation are numerous and complex, and failure rates are high. Based on work we have done primarily with Tipton kangaroo rats and on published information on translocations and reintroductions, we provide recommendations for future translocations or reintroductions of kangaroo rats. If the recommended criteria we offer cannot be satisfied, we advocate that translocations not be attempted. Translocation under less than optimal conditions significantly reduces the probability of success and also raises ethical questions. Key words: Dipodomys heermanni, Dipodomys ingens, Dipodomys nitratoides, reintroduction, San Joaquin Valley, Tipton kangaroo rat, translocation ________________________________________________________________________ Largely due to habitat loss, several species or subspecies of kangaroo rats (Dipodomys spp.) endemic to the San Joaquin Valley of California have been listed by the state and federal governments as endangered. These include the giant kangaroo rat (D. ingens), and two subspecies of the San Joaquin kangaroo rat (D. -

Dipodomys Ingens)
Species Status Assessment Report for the Giant Kangaroo Rat (Dipodomys ingens) Photo by Elizabeth Bainbridge Version 1.0 August 2020 Prepared by the U.S. Fish and Wildlife Service August 2020 GKR SSA Report – August 2020 EXECUTIVE SUMMARY The U.S. Fish and Wildlife Service listed the giant kangaroo rat (Dipodomys ingens) as endangered under the Endangered Species Act in 1987 due to the threats of habitat loss and widespread rodenticide use (Service 1987, entire). The giant kangaroo rat is the largest species in the genus that contains all kangaroo rats. The giant kangaroo rat is found only in south-central California, on the western slopes of the San Joaquin Valley, the Carrizo and Elkhorn Plains, and the Cuyama Valley. The preferred habitat of the giant kangaroo rat is native, sloping annual grasslands with sparse vegetation (Grinnell, 1932; Williams, 1980). This report summarizes the results of a species status assessment (SSA) that the U. S. Fish and Wildlife Service (Service) completed for the giant kangaroo rat. To assess the species’ viability, we used the three conservation biology principles of resiliency, redundancy, and representation (together, the 3Rs). These principles rely on assessing the species at an individual, population, and species level to determine whether the species can persist into the future and avoid extinction by having multiple resilient populations distributed widely across its range. Giant kangaroo rats remain in fragmented habitat patches throughout their historical range. However, some areas where giant kangaroo rats once existed have not had documented occurrences for 30 years or more. The giant kangaroo rat is found in six geographic areas (units), representing the northern, middle, and southern portions of the range.
