  • Dunes Sagebrush Lizard Habitat
    TECHNICAL NOTES U.S. DEPARTMENT OF AGRICULTURE NATURAL RESOURCES CONSERVATION SERVICE NEW MEXICO September, 2011 BIOLOGY TECHNICAL NOTE NO. 53 CRITERIA FOR BRUSH MANAGEMENT (314) in Lesser Prairie-Chicken and Dunes Sagebrush Lizard Habitat Introduction NRCS policy requires that when providing technical and financial assistance NRCS will recommend only conservation treatments that will avoid or minimize adverse effects, and to the extent practicable, provide long-term benefit to federal candidate species (General Manual 190 Part 410.22(E)(7)). This technical note provides the criteria to ensure that the NRCS practice of Brush Management (314) will avoid or minimize any adverse effects to two Candidate Species for Federal listing: the lesser prairie chicken Tympanuchus pallidicinctus (LEPC), and dunes sagebrush lizard Sceloporus arenicolus (DSL). Species Involved The lesser prairie chicken is a species of prairie grouse native to the southern high plains of the U.S.; including the sandhill rangelands of eastern New Mexico. The dunes sagebrush lizard is native only to a small area of southeastern New Mexico and west Texas, with a habitat range that overlaps the lesser prairie chicken range, but only occurs in the sand dune complexes associated with shinnery oak (Quercus havardii Rydb.). Both species’ habitat includes a component of brush: shinnery oak and/or sand sagebrush (Artemisia filifolia Torr.). See Appendix 1 and 2 for more details on each species. Geographic Area Covered by Technical Note No. 53 encompasses private and state lands within the range that supports the dunes sagebrush lizard and lesser prairie chicken habitat. This includes portions of seven counties in New Mexico: Chaves, Curry, De Baca, Eddy, Lea, Roosevelt, and Quay counties.

  • Petition to List the Sand Dune Lizard, Sceloporus Arenicolus As A
    Petition to List the Sand Dune Lizard Sceloporus arenicolus as a Threatened or Endangered Species under the U.S. Endangered Species Act Center for Biological Diversity May, 2002 Ms. Gayle Norton Secretary of the Interior Office of the Secretary Department of the Interior 18th and "C" Street, N.W. Washington, D.C. 20240 The Center for Biological Diversity, Chihuahuan Desert Conservation Alliance and Noah Greenwald hereby formally petition to list the Sand Dune Lizard ( Sceloperus arenicolus) as endangered pursuant to the Endangered Species Act, 16 U.S.C. 1531 et seq. (hereafter referred to as "ESA"). This petition is filed under 5 U.S.C. 553(e) and 50 CFR 424.14 (1990), which grants interested parties the right to petition for issue of a rul e from the Assistant Secretary of the Interior. Petitioners also request that Critical Habitat be designated concurrent with the listing, as required by 16 U.S.C. § 1533(b)(6)(C) and 50 CFR 424.12, and pursuant to the Administrative Procedures Act (5 U.S.C. 553). Petitioners understand that this petition action sets in motion a specific process placing definite response requirements on the U.S. Fish and Wildlife Service and very specific time constraints upon those responses. See 16 U.S.C. § 1533(b). Petitioners: Center for Biological Diversity is a non-profit public interest organization dedicated to protecting the diverse life forms of western North America. It has offices in New Mexico, Arizona, and California. Chihuahuan Desert Conservation Alliance works to encourage the understanding, appreciation and protection of all the elements of the Chihuahuan Desert.

Parallel rays, collected by many lenses, must (through reflection or refraction) cross this transparent clear-zone in such a way that they become focused on one receptor. Superposition depends mostly on diameter and curvature of the cornea, size and shape of the crystalline cone, lens cylinder properties of cornea and cone, dimensions of the receptor cells, and width of the clear-zone. We examined the role of the latter by geometrical, geometric-optical, and anatomical measurements and concluded that a minimal size exists, below which effective superposition can no longer occur. For an eye of a given size, it is not possible to increase the width of the clear-zone cz ¼ dcz=R1 and decrease R2 (i.e., the radius of curvature of the distal retinal surface) and/or c ¼ dc=R1 without reaching a limit.

  • Ventral Coloration and Body Condition Do Not Affect Territorial Behavior in Two Sceloporus Lizards
    Ventral coloration and body condition do not affect territorial behavior in two Sceloporus lizards 1Marina Kelada, 1Courtney Moulton, 2Casey Nguyen, 3Griselda Robles Olague 1University of California, Riverside; 2University of California, Irvine; 3University of California, Santa Barbara Sceloporus lizards are known to be defensive of their territories, which provide shelter, food, water, and mates. They often exhibit territorial behavior through visual displays of aggression, specifically with pushups. Along with aggression, this display can also expose the blue coloration on their ventral side, serving as an intraspecific communication between lizards that reveals information about their dominance, sex, and species membership. In this study, we compared how blue coloration and body condition affected territorial behavior in two Sceloporus lizards: the well-studied western fence (Sceloporus occidentalis) and the understudied sagebrush (Sceloporus graciosus), two closely related lizards with overlapping ranges in the San Jacinto Mountains. We also addressed whether these species would exhibit character displacement in their ventral coloration as a result of their sympatry. ImageJ and Adobe Photoshop were used for photo analyses to quantify the proportion and intensity of blue on each lizard’s ventral side. Territoriality was measured through number of pushups displayed and distance traveled. We found that both ventral coloration and body condition had no effect on the territoriality of either species, suggesting that territorial behavior
