    Tumacacori Potential Wilderness Evaluation Report Tumacacori Potential Wilderness Area Evaluation [PW-05-03-D2-001] Area Overview Size and Location: The Tumacacori Potential Wilderness Area (PWA) encompasses 37,330 acres. This area is located in the Tumacacori and Atacosa Mountains, which are part of the Nogales Ranger District of the Coronado National Forest in southeastern Arizona (see Map 4 at the end of this document). The Tumacacori PWA is overlapped by 30,305 acres of the Tumacacori Inventoried Roadless Area, comprising 81 percent of the PWA. Vicinity, Surroundings and Access: The Tumacacori Potential Wilderness Area is approximately 50 miles southeast of Tucson, Arizona. The Tumacacori PWA is centrally located within the mountain range and encompasses an area from Sardina and Tumacacori Peaks at the northern end to Ruby Road at the southern end and from the El Paso Natural Gas Line on the eastern side to Arivaca Lake on its western side. The PWA is adjacent to the Pajarita Wilderness Area, Arivaca Lake and Peña Blanca Lake. Both Pena Blanca and Arivaca Lakes are managed by the Arizona Game and Fish Department. Interstate 19 (I-19) connects the Tucson metropolitan area to the City of Nogales and the incorporated community of Sahuarita. The unincorporated communities of Green Valley, Arivaca Junction-Amado, Tubac, Tumacacori-Carmen and Rio Rico, Arizona and Sonora, Mexico are within close proximity to the eastern side of the Tumacacori Mountains and the PWA. State Highway 289 provides access from I-19 across private and National Forest System lands into the Tumacacori Ecosystem Management Area to Peña Blanca Lake and Ruby Road (NFS Road 39).

    Birds of Coniferous Forest on Mount Graham, Arizona

    Wilson Bull., 107(4), 1995, pp. 719-723 SHORT COMMUNICATIONS Birds of coniferous forest on Mount Graham, Arizona.-Because of interest in the effect upon the biota of Mount Graham by current development for astronomy, I repeated observations and censuses made there forty years ago. Avifaunal changes have occurred. Unlike my companion study in the Sierra Nevada (Marshall 1988), the losses at Mount Graham of nesting species-all at the lower altitudinal limit of Pinus Zeiophylla chihuahuana and P. ponderosa arizonica-lack an obvious connection to human interference with the environment. Study area.-Mount Graham, in southeastern Arizona, is capped with old growth Engel- mann spruce and alpine fir from 3000 m to the summit at 3267 m. This boreal forest of 8 km* is at its southernmost limits on the North American continent. Descending, one passes through other vegetation zones in sequence: Douglas firs and white firs mixed with spruce, and then mixed with Mexican white pines; south slopes of New Mexican locust and Gambel oak; ponderosa pine with Gambel oak, ponderosa pine mixed with silver-leaf oak; and finally Chihuahua pine with Arizona oak (Martin and Fletcher 1943, Hoffmeister 1956, Marshall 1957, Mohlenbrock 1987). From memory, notes, and photographs I detect no change in vegetation during the forty-year study period. Specifically, the trees at the mapped census area in Wet Canyon (Fig. 1) have not closed ranks about the little openings suitable for those foothill birds that forage among grasses, boulders, manzanitas, and nolinas. The mesic luxuriance of Mount Graham’s vegetation is shown by running streams sup- porting tall groves of maples, by the enormous Douglas firs that remain, by the profusion of understory flowers and green forbs, and by the gigantic stature of clear-trunked alders dominating Wet Canyon.

    The Disastrous Impacts of Trump's Border Wall on Wildlife

    a Wall in the Wild The Disastrous Impacts of Trump’s Border Wall on Wildlife Noah Greenwald, Brian Segee, Tierra Curry and Curt Bradley Center for Biological Diversity, May 2017 Saving Life on Earth Executive Summary rump’s border wall will be a deathblow to already endangered animals on both sides of the U.S.-Mexico border. This report examines the impacts of construction of that wall on threatened and endangered species along the entirety of the nearly 2,000 miles of the border between the United States and Mexico. TThe wall and concurrent border-enforcement activities are a serious human-rights disaster, but the wall will also have severe impacts on wildlife and the environment, leading to direct and indirect habitat destruction. A wall will block movement of many wildlife species, precluding genetic exchange, population rescue and movement of species in response to climate change. This may very well lead to the extinction of the jaguar, ocelot, cactus ferruginous pygmy owl and other species in the United States. To assess the impacts of the wall on imperiled species, we identified all species protected as threatened or endangered under the Endangered Species Act, or under consideration for such protection by the U.S. Fish and Wildlife Service (“candidates”), that have ranges near or crossing the border. We also determined whether any of these species have designated “critical habitat” on the border in the United States. Finally, we reviewed available literature on the impacts of the existing border wall. We found that the border wall will have disastrous impacts on our most vulnerable wildlife, including: 93 threatened, endangered and candidate species would potentially be affected by construction of a wall and related infrastructure spanning the entirety of the border, including jaguars, Mexican gray wolves and Quino checkerspot butterflies.

    Wild Cats of the Sky Islands: A Summary of Monitoring Efforts Using Noninvasive Techniques Lisa Haynes, Zoe Hackl, and Melanie Culver School of Renewable Natural Resources, University of Arizona, Tucson, AZ Abstract—A variety of efforts are taking place to detect, inventory, and monitor the wild felids (pumas, bobcats, jaguars, and ocelots) of the Madrean Archipelago. Researchers are using a suite of noninvasive methods, including infrared-triggered photography, DNA analysis of scat and hair (collected from “hair snares”), and old-fashioned tracking and sign searches. These efforts are being conducted by a variety of academic, government, and non-governmental organizations in the United States and Mexico. We briefly outline the various projects including their results to date, discuss threats to native felids in the region, and provide recommendations for further research, monitoring, and conservation. wildlife—all contributed to a recent flurry of activity to gather Introduction information on the wild cats of the Madrean Archipelago.

    Evol Ecol DOI 10.1007/s10682-013-9656-9 REVIEW ARTICLE Eavesdropping on visual secrets Nicholas C. Brandley • Daniel I. Speiser • So¨nke Johnsen Received: 22 October 2012 / Accepted: 28 May 2013 Ó Springer Science+Business Media Dordrecht 2013 Abstract Private communication may benefit signalers by reducing the costs imposed by potential eavesdroppers such as parasites, predators, prey, or rivals. It is likely that private communication channels are influenced by the evolution of signalers, intended receivers, and potential eavesdroppers, but most studies only examine how private communication benefits signalers. Here, we address this shortcoming by examining visual private com- munication from a potential eavesdropper’s perspective. Specifically, we ask if a signaler would face fitness consequences if a potential eavesdropper could detect its signal more clearly. By integrating studies on private communication with those on the evolution of vision, we suggest that published studies find few taxon-based constraints that could keep potential eavesdroppers from detecting most hypothesized forms of visual private com- munication. However, we find that private signals may persist over evolutionary time if the benefits of detecting a particular signal do not outweigh the functional costs a potential eavesdropper would suffer from evolving the ability to detect it. We also suggest that all undetectable signals are not necessarily private signals: potential eavesdroppers may not benefit from detecting a signal if it co-occurs with signals in other more detectable sensory modalities. In future work, we suggest that researchers consider how the evolution of potential eavesdroppers’ sensory systems influences private communication.

  • Polarisation Signals

    Polarisation Signals

    Chapter 19 Polarisation Signals Justin Marshall, Nicholas Roberts, and Thomas Cronin Abstract Humans are fascinated by the colour vision, colour signals and ‘dress codes’ of other animals as we can see colour. This property of light may be useful for increasing the contrast of objects during foraging, defence, camouflage and sexual communication. New research, largely from the last decade, now suggests that polarisation is a quality of light also used in signalling and may contain information at least as rich as colour. As many of the chapters in this book detail, polarisation in animals is often associated with navigation, habitat choice and other tasks that require large-field processing. That is, a wide area of the light field, such as the celestial hemisphere, is sampled from. Polarisation vision that recognises and extracts information from objects is most likely confined to processing through small numbers of receptors. This chapter examines the latest evidence on polarised signals from animals and their environments, including both linear and circular polarisations. Both aquatic and terrestrial examples are detailed, but with emphasis on life underwater as it is here that many recent discoveries have been made. Behaviour relative to signals is described where known, and suggestions are given as to how these signals are received and processed by the visual system. Camouflage as well as signalling in this light domain is also considered, with the inevitable conclusion for this new field that we need to know more before solid conclusions can be drawn. J.
