Gómez Palacio, 35070, Durango, México Submitted on 2012, 5th December; revised on 2013, 10th August; accepted on 2013, 3rd September. Abstract. The life history of a population of marbled whiptail lizard, Aspidoscelis marmorata, was examined from 1989 to 1994 in the sand dunes of the Biosphere Reserve of Mapimí, in Northern México. Lizards were studied using mark- recapture techniques. Reproduction in females occurred between May and August, with birth hatchlings matching the wet season in August. Reproductive activity was highest in the early wet season (July). Males and females reached adult size class at an average age of 1.7 years and 1.8 years, respectively. Body size of males attained an asymptote around 90 mm snout-vent length and females around 82 mm snout-vent length, at an age of approximately 3.6 years and 3.0 years, respectively. The density varied from 7 to 85 individuals / 1.0 ha. The Mexican population had late maturity, relatively long life expectancy, and fewer offspring. Overall, the observed data for A. marmorata and the expectations of life history theory for a late maturing species (K-rate selection) are in agreement.

  • The Importance of Assessing Climate Change Vulnerability to Address Species Conservation Karen E
    Issues and Perspectives The Importance of Assessing Climate Change Vulnerability to Address Species Conservation Karen E. Bagne,* Megan M. Friggens, Sharon J. Coe, Deborah M. Finch U.S. Department of Agriculture Forest Service, Rocky Mountain Research Station, Albuquerque, New Mexico 87102 Present address of K.E. Bagne: Department of Biology, Kenyon College, Gambier, Ohio 43022 Abstract Species conservation often prioritizes attention on a small subset of ‘‘special status’’ species at high risk of extinction, but actions based on current lists of special status species may not effectively moderate biodiversity loss if climate change alters threats. Assessments of climate change vulnerability may provide a method to enhance identification of species at risk of extinction. We compared climate change vulnerability and lists of special status species to examine the adequacy of current lists to represent species at risk of extinction in the coming decades. The comparison was made for terrestrial vertebrates in a regionally important management area of the southwestern United States. Many species not listed as special status were vulnerable to increased extinction risk with climate change. Overall, 74% of vulnerable species were not included in lists of special status and omissions were greatest for birds and reptiles. Most special status species were identified as additionally vulnerable to climate change impacts and there was little evidence to indicate the outlook for these species might improve with climate change, which suggests that existing conservation efforts will need to be intensified. Current special status lists encompassed climate change vulnerability best if climate change was expected to exacerbate current threats, such as the loss of wetlands, but often overlooked climate-driven threats, such as exceeding physiological thresholds.

  • Environmental Consequences
    5-Mile Zone Protective and Regulatory Pumping Unit RMP/EA Water Rights The use of water in the 5-mile zone is regulated by (1) a 1989 Reclamation memorandum that is based in part on Public Law 93-320, as amended by Public Law 96-336; (2) IBWC 242 Minute; (3) existing water contracts; and (4) all applicable Federal and State regulations. Public Law 96-336 states that no contract shall be entered into that will impair the ability of the United States to continue to deliver to Mexico, on the Colorado River downstream from Morelos Dam, approximately 140,000 acre-feet of water annually, consistent with the terms contained in IBWC 242 Minute. Therefore, any request for water use from the study area would be subject to these limitations. Environmental Consequences Increased pumping from the aquifer, which could occur under alternatives that allow for development or land transfers or exchanges that would use or require more water, would affect groundwater availability in the study area. Some water use could occur in the 5-mile zone, west of the study area and outside of Reclamation’s jurisdiction, such as near the city of San Luis. Some elements of the alternatives could also affect groundwater quality. Following are the anticipated effects of each alternative. Alternative A Under Alternative A, if groundwater were used to meet the water needs of new developments, the aquifer could be lowered. However, the quantities needed should not adversely affect Reclamation=s ability to meet its water delivery obligations to Mexico unless total pumpage for the 5-mile zone approaches 160,000 acre-feet per year, the limit stipulated by IBWC 242 Minute.

Objectives for this inventory were to: 1) Inventory and document the occurrence of reptile and amphibian species occurring at DEVA, primarily within priority sampling areas, with the goal of documenting at least 90% of the species present; 2) document (through collection or museum specimen and literature review) one voucher specimen for each species identified; 3) provide a GIS-referenced list of sensitive species that are federally or state listed, rare, or worthy of special consideration that occur within priority sampling locations; 4) describe park-wide distribution of federally- or state-listed, rare, or special concern species; 5) enter all species data into the National Park Service NPSpecies database; and 6) provide all deliverables as outlined in the Mojave Network Biological Inventory Study Plan. Methods included daytime and nighttime visual encounter surveys, road driving, and pitfall trapping. Survey effort was concentrated in predetermined priority sampling areas, as well as in areas with a high potential for detecting undocumented species.

  • Monitoring Science and Technology Symposium
    Herpetological Communities of the Middle Rio Grande Bosque: What Do We Know, What Should We Know, and Why? Alice L. Chung-MacCoubrey, Research Wildlife Biologist, USDA Forest Service, Rocky Mountain Research Station, Albuquerque, NM Heather L. Bateman, Graduate Student, Department of Biology, University of New Mexico, Albuquerque, NM Abstract—Amphibians and reptiles (herpetofauna) play important roles within eco- systems. Similar to many birds and mammals, they are major consumers of terrestrial arthropods. However, amphibians and reptiles are more efficient at converting food into biomass and are a higher quality food source for predators. Recent declines in some herpetofaunal populations have stimulated a greater overall interest in the monitoring of these populations. Although studies have examined the use of exotic plant-invaded ecosystems by birds and mammals, few have focused on the herpetofaunal community. Specifically, there is little information on the ecology and management of reptiles and amphibians within riparian cottonwood forest (bosque) along the Middle Rio Grande in New Mexico. Invasion by exotic plant species and accumulation of woody debris have led to high fuel loadings and thus the risk of catastrophic fire in the bosque. Thus, land managers are interested in removing exotics and reducing fuels by various techniques. To effectively manage habitat and make sound decisions, managers must understand how various fuels reduction treatments affect wildlife communities, including the dis- tribution, abundance, and ecology of amphibian and reptile populations. In 1999, the U.S. Forest Service- Rocky Mountain Research Station initiated a study to monitor and evaluate the response of vegetation and wildlife to three fuel reduction treatments in the Middle Rio Grande bosque.

We utilized five species distribution models (SDM) including Generalized Linear Model, Random Forest, Boosted Regression Tree, Maxent and Multivariate Adaptive Regression Splines to develop the present day distributions of the species based on climate-driven models alone. We then projected future distributions of whiptails using data from four climate models run according to two greenhouse gas concentration scenarios (RCP 4.5 and RCP 8.5). Results of A. tesselata species group suggested that climate change will negatively affect the bioclimatic habitat and distribution of some species, while projecting gains in suitability for others. Furthermore, when the species group was analyzed together, climate projections changed for some species compared to when they were analyzed alone, suggesting significant loss of syntopic areas where suitable climatic conditions for more than two species would persist. In other words, syntopy within members of the species group will be drastically reduced according to future bioclimatic suitability projections in this study.
