  • 5-Year Review Short Form Summary
    5-Year Review Short Form Summary Species Reviewed: Preble’s meadow jumping mouse (Zapus hudsonius preblei) FR Notice Announcing Initiation of This Review: March 31, 2004. 90-Day Finding for a Petition to Delist the Preble’s Meadow Jumping Mouse in Colorado and Wyoming and Initiation of a 5-Year Review (69 FR 16944-16946). Lead Region/Field Office: Region 6, Seth Willey, Recovery Coordinator, 303-236-4257. Colorado Field Office, Susan Linner, Field Supervisor, 303-236-4773. Name of Reviewer: Peter Plage, Colorado Field Office, 303-236-4750. Cooperating Field Office: Wyoming Field Office, Brian Kelly, Field Supervisor, 307-772-2374. Current Classification: Threatened rangewide. Current Recovery Priority Number: 9c. This recovery priority number is indicative of a subspecies facing a moderate degree of threat, a high recovery potential, and whose recovery may be in conflict with construction or other development projects or other forms of economic activity. Methodology used to complete the review: The 5-year review for the Preble’s meadow jumping mouse (Preble’s) was accomplished through the petition and rulemaking process. On December 23, 2003, we received two nearly identical petitions from the State of Wyoming’s Office of the Governor and from Coloradans for Water Conservation and Development, seeking to remove the Preble’s from the Federal List of Endangered and Threatened Wildlife. Both petitions were similar and maintained that the Preble’s should be delisted based on the taxonomic revision, and based on new distribution, abundance, and trends data that suggested the Preble’s was no longer threatened. On March 31, 2004, we published a notice announcing a 90-day finding that the petitions presented substantial information indicating that the petitioned action may be warranted and initiated a 5-year review (69 FR 16944-16946).

    BEFORE THE SECRETARY OF THE INTERIOR Petition to List the Preble’s Meadow Jumping Mouse (Zapus hudsonius preblei) as a Distinct Population Segment under the Endangered Species Act November 9, 2017 Petitioners: Center for Biological Diversity Rocky Mountain Wild Acknowledgment: Conservation Intern Shane O’Neal substantially contributed to drafting of this petition. November 9, 2017 Mr. Ryan Zinke CC: Ms. Noreen Walsh Secretary of the Interior Mountain-Prairie Regional Director Department of the Interior U.S. Fish and Wildlife Service 18th and C Street, N.W. 134 Union Boulevard, Suite 650 Washington, D.C. 20240 Lakewood, CO 80228 [email protected] Dear Mr. Zinke, Pursuant to Section 4(b) of the Endangered Species Act (“ESA”), 16 U.S.C. §1533(b), Section 553(3) of the Administrative Procedures Act, 5 U.S.C. § 553(e), and 50 C.F.R. §424.14(a), the Center for Biological Diversity and Rocky Mountain Wild hereby formally petitions the Secretary of the Interior, through the United States Fish and Wildlife Service (“FWS”, “the Service”) to list the Preble’s meadow jumping mouse (Zapus hudsonius preblei) as a distinct population segment. Although the Preble’s meadow jumping mouse is already currently listed as a subspecies, this petition is necessary because of a petition seeking to de-list the Preble’s meadow jumping mouse (“jumping mouse”, “Preble’s”), filed by the Pacific Legal Foundation on behalf of their clients (PLF 2017), arguing that the jumping mouse no longer qualifies as a subspecies. Should FWS find this petition warrants further consideration (e.g. a positive 90-day finding), we are submitting this petition to ensure that the agency simultaneously considers listing the Preble’s as a distinct population segment of the meadow jumping mouse.

  • Species Status Assessment Report New Mexico Meadow Jumping Mouse (Zapus Hudsonius Luteus)
    Species Status Assessment Report New Mexico meadow jumping mouse (Zapus hudsonius luteus) (photo courtesy of J. Frey) Prepared by the Listing Review Team U.S. Fish and Wildlife Service Albuquerque, New Mexico May 27, 2014 New Mexico Meadow Jumping Mouse SSA May 27, 2014 EXECUTIVE SUMMARY This species status assessment reports the results of the comprehensive status review for the New Mexico meadow jumping mouse (Zapus hudsonius luteus) (jumping mouse) and provides a thorough account of the species’ overall viability and, conversely, extinction risk. The jumping mouse is a small mammal whose historical distribution likely included riparian areas and wetlands along streams in the Sangre de Cristo and San Juan Mountains from southern Colorado to central New Mexico, including the Jemez and Sacramento Mountains and the Rio Grande Valley from Española to Bosque del Apache National Wildlife Refuge, and into parts of the White Mountains in eastern Arizona. In conducting our status assessment we first considered what the New Mexico meadow jumping mouse needs to ensure viability. We generally define viability as the ability of the species to persist over the long-term and, conversely, to avoid extinction. We next evaluated whether the identified needs of the New Mexico meadow jumping mouse are currently available and the repercussions to the subspecies when provision of those needs are missing or diminished. We then consider the factors that are causing the species to lack what it needs, including historical, current, and future factors. Finally, considering the information reviewed, we evaluate the current status and future viability of the species in terms of resiliency, redundancy, and representation.

  • The Phylogenetic Roots of Human Lethal Violence José María Gómez1,2, Miguel Verdú3, Adela González-Megías4 & Marcos Méndez5
    LETTER doi:10.1038/nature19758 The phylogenetic roots of human lethal violence José María Gómez1,2, Miguel Verdú3, Adela González-Megías4 & Marcos Méndez5 The psychological, sociological and evolutionary roots of 600 human populations, ranging from the Palaeolithic era to the present conspecific violence in humans are still debated, despite attracting (Supplementary Information section 9c). The level of lethal violence the attention of intellectuals for over two millennia1–11. Here we was defined as the probability of dying from intraspecific violence propose a conceptual approach towards understanding these roots compared to all other causes. More specifically, we calculated the level based on the assumption that aggression in mammals, including of lethal violence as the percentage, with respect to all documented humans, has a significant phylogenetic component. By compiling sources of mortality, of total deaths due to conspecifics (these sources of mortality from a comprehensive sample of mammals, were infanticide, cannibalism, inter-group aggression and any other we assessed the percentage of deaths due to conspecifics and, type of intraspecific killings in non-human mammals; war, homicide, using phylogenetic comparative tools, predicted this value for infanticide, execution, and any other kind of intentional conspecific humans. The proportion of human deaths phylogenetically killing in humans). predicted to be caused by interpersonal violence stood at 2%. Lethal violence is reported for almost 40% of the studied mammal This value was similar to the one phylogenetically inferred for species (Supplementary Information section 9a). This is probably the evolutionary ancestor of primates and apes, indicating that a an underestimation, because information is not available for many certain level of lethal violence arises owing to our position within species.

    Variation in phenology of hibernation and reproduction in the endangered New Mexico meadow jumping mouse (Zapus hudsonius luteus) Jennifer K. Frey Department of Fish, Wildlife, and Conservation Ecology, New Mexico State University, Las Cruces, NM, United States of America Frey Biological Research, Radium Springs, NM, United States of America ABSTRACT Hibernation is a key life history feature that can impact many other crucial aspects of a species’ biology, such as its survival and reproduction. I examined the timing of hibernation and reproduction in the federally endangered New Mexico meadow jumping mouse (Zapus hudsonius luteus), which occurs across a broad range of latitudes and elevations in the American Southwest. Data from museum specimens and field studies supported predictions for later emergence and shorter active intervals in montane populations relative to lower elevation valley populations. A low-elevation population located at Bosque del Apache National Wildlife Refuge (BANWR) in the Rio Grande valley was most similar to other subspecies of Z. hudsonius: the first emergence date was in mid-May and there was an active interval of 162 days. In montane populations of Z. h. luteus, the date of first emergence was delayed until mid-June and the active interval was reduced to ca 124–135 days, similar to some populations of the western jumping mouse (Z. princeps). Last date of immergence into hibernation occurred at about the same time in all populations (mid to late October). In montane populations pregnant females are known from July to late August and evidence suggests that they have a single litter per year. At BANWR two peaks in reproduction were expected based Submitted 6 May 2015 on similarity of active season to Z.

Determination of Endangered Status for the New Mexico Meadow Jumping Mouse Throughout Its Range (79 FR 33119) • March 16, 2016. Designation of Critical Habitat for the New Mexico Meadow Jumping Mouse; Final Rule ( 81 FR 14263) Classification: Endangered 1.2 Methodology used to complete the review: In accordance with section 4(c)(2) of the Endangered Species Act of 1973, as amended (Act), the purpose of a 5-year review is to assess each threatened species and endangered species to determine whether its status has changed and it should be classified differently or removed from the Lists of Threatened and Endangered Wildlife and Plants. The U.S. Fish and Wildlife Service (Service) recently evaluated the biological status of the New Mexico meadow jumping mouse to update the original 2014 Species Status Assessment (SSA) report (Service 2014). The original SSA report supported the listing of the species as endangered in 2014 and the designation of critical habitat in 2016 within eight separate geographical management areas (GMAs). The updated SSA report (Service 2020) contains the scientific basis that the Service is using to inform this 5-year review, guiding future research projects that will answer key questions about the life history and ecology of the species, and supporting further recovery planning and implementation.
