Riparian ecosystems are among the most productive biological systems providing food, water, shade, and cover for wildlife (Thomas et al. 1979a). Furthermore, they may display a greater diversity of plant and animal species and vegetative structure than adjacent ecosystems (USDI 1986). Thomas et al. (1979a) provide a descriptive definition which characterizes riparian ecosystems by the presence of trees, shrubs, or herbaceous vegetation that require free or unbound water, or conditions that are more moist than those of the surrounding areas. They suggest that more wildlife species depend entirely on or spend disproportionally more time in riparian habitat than any other. Although the importance of riparian vegetation to wildlife has been apparent since the 1970's, its overall importance to vertebrate species has not been widely studied, especially in the western United States (Patton 1977). Elsewhere, there is a paucity of information on the ecological role of small mammals in riparian areas. Because small vertebrate species may serve as an especially important link in the food chain of threatened, endangered, or reintroduced species, and because small mammal species seem to be compacted in environmentally diverse areas, analysis of riparian vertebrate communities should provide important insights in mechanisms of habitat subdivision and utilization. Clearly, riparian areas contain a greater variety of species than adjoining forest or upslope habitats (Cross 1985). The effect of patch shape on the number of species occupying riparian habitats also has received limited attention (Patton 1975). Because riparian habitat consists of a narrow patch, the elongated shape of riparian areas produces a low interior-to­high-edge ratio which may facilitate or enhance ecological processes, especially the production and dispersal of small mammals. Unfortunately, no documentation exists about patterns of mammalian movement along stream corridors (Forman and Godron 1986). Thus, the importance of the relative use of the edge, riparian, and upland areas by small mammals needs to be investigated, especially in forested mountain land, where riparian areas tend to have smaller areal extent and economic value than upslope vegetation (Swanson et al. 1982). The principle objective of our study was to determine if consistent environmental and landscape features could be found in western riparian, edge, and upland communities, and if these features affected residency of small mammals in Grand Teton National Park. Three independent study sites were studied from June, 1991 through October, 1991 in preparation for a proposed long-term analysis of the role of riparian areas in production of small mammals.

Sylvatic plague (Yersinia pestis) and tularemia (Francisella tularensis) are infectious bacterial diseases that can be transmitted from wild mammals to humans by insects or through direct contact. Although cases of plague and tularemia have been reported in the southwest, a comprehensive understanding of the prevalence, distribution and dynamics of these diseases is lacking. During the months of June and July 2000 we sampled small mammals in Grand Teton National Park (GTNP) for antibodies of these zoonotic diseases. This survey was conducted in conjunction with a large scale population dynamics study, lead by Dr. Brian Miller, Denver Zoological society, and Dr. Hank Harlow, Department of Zoology and Physiology, University of Wyoming. A published survey of plague and tularemia has not been conducted in GTNP. In 1996, Dr. Fredrick Jannett looked for plague in the genus Microtus and found low incidence

The Impact

Concessioners play an important role in park and protected area management by providing visitor services. Historically, concessioners were criticized for their negative impacts on environmental sustainability. However, due to policy changes, technological advances, and shifting market demands, there is a need to reevaluate the role of concessioners in sustainable destination management in and around parks and protected areas. The purpose of this qualitative case study situated in Grand Teton National Park (GTNP), which was guided by social exchange theory, was to explore U.S. national park concessioners’ influence on sustainable development at the destination level from the perspective of National Park Service (NPS) staff, concessioners, and local community members. Sustainability was examined holistically as a multifaceted construct with integrated socioeconomic, cultural, and environmental dimensions. Twenty-three participants completed semistructured interviews. Researchers identified four thematic categories describing concessioners’ influence on sustainability; motivations and barriers to pursuing sustainability initiatives; and situational factors that facilitated concessioners’ sustainability actions. While participants commented on the negative environmental impacts of concessioners and their operations, these data suggest that concessioners were working individually and collaboratively to promote environmental, socioeconomic, and cultural sustainability in and around GTNP. Some concessioners were even described as leaders, testing and driving the development of innovative sustainability policies and practices. These actions were motivated, in part, by contractual obligations and profit generation. However, concessioners also had strong intangible motivators, such as intrinsic values and a strong sense of community, that drove their positive contributions to sustainability. Based on these data, we recommend that those involved in future theoretical and practical work with concessioners acknowledge the importance of both tangible and intangible motivators when attempting to promote higher levels of sustainability achievement and collaboration. This will become increasingly important as land management agencies continue to embrace strategies beyond the traditional “parks as islands” approach to management. Additionally, future work should explore more specifically the role of policy, conceptualizations of sustainability, and private industry sponsorship in promoting concessioners’ contributions to sustainability, especially in collaborative settings. This work is needed to understand if and how these observations generalize to other contexts.

Small mammal surveys were conducted at Niah National Park, Lambir Hills National Park and Gunung Mulu National Park, Miri Division, in the northeastern region of Sarawak, using ground-level and canopy mist-nets, harp traps, and cage traps. The main objective of these surveys was to assess small mammal diversity in the northeastern region of Sarawak. Gunung Mulu National Park recorded the highest diversity of small mammals with 29 species, followed by Niah National Park with 19 species, and Lambir Hills National Park, 17 species. These surveys revealed nine new locality records for Miri, including eight bat species (Dyacopterus spadiceus, Megaerops wetmorei, Nycteris tragata, Hipposideros cineraceus, Hesperoptenus blanfordi, Kerivoula pellucida, Murina suilla and Myotis muricola)and a squirrel (Sundasciurus brookei). Megaerops wetmorei is also reported for the first time in Sarawak.

In a review of the parasites of Microtus, Timm (1985) lists no protozoan endoparasites whatsoever for this genus. The role of parasitism, whether macro- or microparasites, and whether endo- or ectoparasites, in the demographic machinery of microtines is poorly understood. Timm (1985) astutely observes that one of the most challenging and fruitful directions of future research with Microtus will be the statistical quantification of the cost of parasitism. In addition, since humans in the Grand Teton National Park may encounter protozoon parasites that are potentially pathogenic to humans, it is useful to characterize the occurrence and biology of such organisms in the parko Babesia microti, a parasitic protozoon, is transmitted by a tick vector and reproduces in the erythrocytes of its mammalian host. Initially, Babesia was thought to be restricted to small mammals; however, in 1970 the first human cases were diagnosed in residents of Nantucket Island, Massachusetts (Western et al, 1970). Over 200 cases of human babesiosis have been documented worldwide. In the United States, human babesiosis is caused by B. microti. Most of these cases have occurred in the eastern United States. The earliest report of an organism that fits the description of Babesia in human erythrocytes is that of Wilson et al. (1904), who found an unknown organism in human erythrocytes while investigating the cause of Rocky Mountain Spotted fever. Documented cases of babesiosis in many areas of the United States are increasing (Steketee et al, 1985). As humans insert themselves into places where they have historically been present only occasionally, they often contract new diseases. A second protozoon parasite, Hepatozoon sp., which is widespread in small mammals in Europe, is also found in reptiles throughout the world. The record of Hepatozoon in North American small mammals is not extensive. Fewer than 10 species of mammals have been shown to harbor Hepatozoon parasites. Like Babesia, Hepatozoon is a two-host parasite. Unlike Babesia, for which the intermediate host is always a tick, the intermediate host in the Hepatozoon may be a tick, a mite, a flea, or a mosquito. The method of transmission by the vector also differs in the two parasites. Babesia is transmitted in saliva when the tick bites, whereas Hepatozoon infection requires the vertebrate host to swallow the vector. In our 1994 studies, we sought to extend knowledge of these two parasites. The specific objectives for 1994 were: to sample specific populations of M. molltanus, in which we have previously documented Hepatozoon infections, to determine whether there are differences in the infection rates at different study sites in the park; to search for the vector of Hepatozoon sp. infections in M. montanus by examining ectoparasites; to collect and rear ticks from M. montanus for use in R microti transmission studies; and to complete a comparison of the spleen histology of babesiosis in infected and uninfected laboratory animals, with inclusion of data from wild animals, as available. Our long-term objectives are to document the effects and cost of parasitism on vole populations and to determine the potential of small mammals of Grand Teton National Park to serve as reservoirs of human parasites.
