The broad, long-term objectives of this study are (1) to determine what species of higher fungi grow in forest, range, and pasturelands in and around Grand Teton National Park: (2) to appraise their role in the ecosystem; and (3) to prepare descriptions, keys and illistrations for the common species. These are approached simultaneously although smaller, specific segments are emphasized in different collecting seasons.

This study attempts to inventory the mushrooms and related fungi of the Park and to assemble correlative data useful in park resource management and utilization. It is directed toward (1) determining what species of higher fungi grow in and around Grand Teton National Park; (2) appraising their role in the ecosystem; and (3) preparing descriptions, illustrations, and where possible, keys for the common species. Fungi included are mostly Ascomycetes and Basidiomycetes with large or otherwise conspicuous fruiting bodies. Collecting is not confined to Grand Teton National Park but includes sites with similar ecology in the areas surrounding the Park.

The 2 weeks field studies during June of 1987 continued work on that part of the previously stated objectives (e.g. McKnight, Harper, & McKnight, 1986) concerned with the inventory of fungal species in the Wyoming national parks, particularly Grand Teton National Park. The specific objectives were to (1) study species of the genus Cortinarius, section Leprocybe, particularly those in the subsection Zinziberati to further clarify species concepts and relationships of species collected earlier, especially those of the 1983 and 1987 collecting seasons; (2) obtain illustrations of species for a revision of the previously published Checklist (McKnight, 1982) and a fieldguide of common species in the Grand Teton-Yellowstone area now in preparation.

The changes in the diet of foxes (Vulpes vulpes) in the Jervis Bay Region was assessed following a long-term baiting program by analysing the composition of fox faecal excreta (scats). In all, 470 fox scats were collected between April and August 2003 from two baited sites, Booderee National Park (BNP) and Beecroft Peninsula, and from two unbaited sites in the southern and northern parts of Jervis Bay National Park (SJBNP and NJBNP respectively). Diet was compared between these sites and mammalian diet was also compared from scats collected before baiting in 1996 and after baiting in 2000 at Beecroft Peninsula and in 2001 at Booderee National Park. In 2003, the most common species consumed by foxes was the common ringtail possum (Pseudocheirus peregrinus), except at unbaited NJBNP, where the swamp wallaby (Wallabia bicolor) was the most frequent dietary item. Significant dietary differences were found between unbaited and baited sites, with the long-nosed bandicoot (Perameles nasuta) and P. peregrinus featuring more in the diet of foxes from the baited sites. Marked increases in the frequency of occurrence of P. peregrinus and P. nasuta in fox scats occurred from before baiting through to after baiting. Relative fox abundance, as indexed by the number of scats collected per kilometre, was lowest in Booderee, followed by Beecroft, then SJBNP, with NJBNP having the highest relative abundance of foxes. We suggest that baiting did affect the diet of foxes on both peninsulas and that the dietary changes across baiting histories were intrinsically related to an increase in abundance in some taxa as a result of relaxed predator pressure following sustained fox control. However, the lack of unbaited control sites over the whole study precludes a definitive conclusion.

  The welfare level of the population in Wasur Park village is still very low and most still hang its life by taking the result of the forest. This study aims to analyze the role of Wasur Park National Park in increasing local people's income. The method by which researchers use a qualitative approach, while the data collection techniques consist of library studies and field studies through observation, interviews. The process of data analysis includes data reduction, data presentation, and the conclusion of the empowerment of the National Park Wasur Park Hall is counseling to the local community in the framework of the Empowerment Program of local Kampung Wasur Park. In the empowerment, Wasur Park National Park is coordinating with local governments to see the development of local community data. The real evidence of Wasur Park National Park through empowerment is the establishment of a rural forestry Counseling Center (SPKP). The establishment of a rural forestry Counseling Center (SPKP) in Wasur Village, implemented after the implementation of education and training of village studies in participatory. Furthermore, Wasur Park National Park Hall conducts construction. The construction is a construction of small industry of eucalyptus oil refining, the manufacture of salted fish, medicinal plants, and the cultivation of commercial crops. Then the community in providing coaching through socialization by providing science about preserving the forest and protection and safeguarding the potential of Wasur National Park area. Then Wasur Park National Park Hall conducts supervision. Supervision conducted by the National Park Hall Wasur Park is monitoring against the hunting of many protected animals located in Wasur Park National Park area. In the Garden Hall program, Wasur Park is monitoring and evaluation of habitat and population. The Wasur Park National Park Hall conducts a regular patrol, preventing wild hunters from Wasur Park National Park. Then patrol is also done to prevent forest fires.

AbstractThe Republic of Guinea is thought to contain the largest population of common hippopotamus in West Africa. However, no systematic field survey has been carried out recently and the information available is limited to informal observations. To clarify the status of the common hippopotamus in Guinea, we carried out a biannual population survey along the section of the Niger River (the largest river in Guinea) within the Haut Niger National Park. We counted 93 hippopotamuses in 28 groups in the dry season and 77 hippopotamuses in 23 groups in the wet season. Mean group size and number of neonates did not change between the seasons. Hippopotomuses were more numerous along the river sections bordering uncultivated floodplains. This underlines the significance of this habitat (which is used as a grazing area) for conservation of this species. Haut Niger National Park is the most important protected area in Guinea for conservation of the common hippopotamus. Hippopotamus-human and -cattle conflicts in terms of floodplain use in the park's buffer zone should be closely monitored. Floodplain conversion to rice fields represents one of the most important threats to the long-term conservation of hippopotamus populations in Guinea.

Eight in-service teachers and two instructors engaged in an inquiry-based geology field course from June 14 to 29, 2014 through Wyoming, South Dakota, and Nebraska. This team of learners spent three days in mid-June working in the Grand Teton National Park area. The UW-NPS facilities provide an excellent opportunity for participants to discover the natural history of the Teton Range, as well as close-out a few projects while sitting in a real chair, at a real table, a welcome change from our usual campground setting.

Our objective is to establish a long-term monitoring project that will assess the abundance and densities of selected species of mammals at sites representing five defined vegetation types found in Grand Teton National Park. The term monitoring implies data collection over multiple years. Taking long term estimations of population composition before, during, and after biotic and abiotic changes provides needed information to assess the impacts of such changes and furnish useful options for management decisions. This standardized monitoring plan will provide information on small and medium-sized mammals that will (1) assess species use of habitat, (2) monitor changes in species composition as a result of environmental change, such as precipitation and temperature, (3) produce predictive models of small and medium-sized mammal distribution based on vegetation type, and (4) analyze the impact of wolf colonization on the mammal (and plant) community.

Eight in-service teachers, one pre-service education student, three observers from other universities, and two instructors from the University of Nebraska-Lincoln engaged in an inquiry-based geology field course from June 13 to 28, 2015 through Wyoming, South Dakota, and Nebraska. This commnity of learners spent three days working in the Grand Teton National Park area. Geological features and history present in Grand Teton National Park are an important part of the course curriculum. Large-scale extensional features of the Teton Range and Jackson Hole, and the glacial geomorphology and related climate changes of this area are some of the unique features examined here.

AbstractThis paper evaluates water quality and ecological status of lakes located in the Wielkopolska National Park and its buffer zone. Changes in water quality were analyzed from 1974 to 2012 in order to assess the effectiveness of the protection strategies implemented on the studied lakes since 1957, i.e. the date when the park was established. The ecological status of the lakes was assessed with the use of macrophytes as well as hydromorphological and physicochemical analyses performed in 2012. Changes in water quality of the studied lakes within the last 40 years were analyzed based on available published and unpublished data, as well as field studies. All water bodies are characterized by advanced eutrophication. However, evaluation of the ecological status showed good status of the charophyte-dominated lakes, i.e. Lake Wielkowiejskie and Lake Budzyńskie. Lack of significant differences in physicochemical water qualities between the park and its buffer zone indicated that measures implemented to protect the water, particularly in the park, are ineffective. This study shows that more radical conservation measures are necessary to protect and improve the water quality, not only in WPN and its buffer zone but also in the whole catchment area.
