Ozone-sensitive and -tolerant individuals of cutleaf coneflower (Rudbeckia laciniata L.) were compared for their gas exchange characteristics and total non-structural carbohydrates at Purchase Knob, a high elevation site in Great Smoky Mountains National Park, USA. Photosynthesis and stomatal conductance decreased with increased foliar stipple. Sensitive plants had lower photosynthetic rates fo...

Researchers at the Center for Remote Sensing and Mapping Science (CRMS) at The University of Georgia have worked with the U.S. Department of Interior National Park Service (NPS) over the past decade to create detailed vegetation databases for several National Parks and Historic Sites in the southeastern United States. The sizes of the parks under investigation vary from Everglades National Park...

Dead leaves of Dasylirion were collected in Texas in Guadalupe Mountains National Park and Big Bend National Park, and in the Valley of Fires, New Mexico. The fungi present were identified and grown in culture to identify teleomorph-anamorph connections. Four new ascomycete species are described-Graphyllium dasylirionis, Splanchnonema dasylirionis, Chaetoplea dasylirionis, and Chaetoplea sotoli...

Most research into the diet of stoats in New Zealand has been in low altitude valleys such as the Eglinton and Hollyford Valleys. Yet much of New Zealand’s national parks (e.g. Fiordland National Park) consist of many small montane valleys and alpine areas. This research identified the key prey species of stoats inhabiting such small montane valleys and alpine grasslands. Stoats were collected ...

Four new species of the subgenus Hoplophorella are desccribed and identified from the Afrotropical region: Atropacarus (Hoplophorella) curtisetosus sp. nov. from Uluguru Mountains of Tanzania, Atropacarus (Hoplophorella) distinctus sp. nov. from Ambohitantely Special Reserve of Madagascar, Atropacarus (Hoplophorella) othneios sp. nov. from Ranomafana National Park of Masagascar, and Atropacarus...

We report on a systematic survey of the ant fauna occurring in hardwood forests in the Great Smoky Mountains National Park. At 22-mixed hardwood sites, we collected leaf-litter ant species using Winkler samplers. At eight of those sites, we also collected ants using pitfall and Malaise traps. In total, we collected 53 ant species. As shown in other studies, ant species richness tended to declin...

The sensitivity of high-elevation lakes to acidic deposition was evaluated in five national parks of the Rocky Mountains based on statistical relations between lake acid-neutralizing capacity concentrations and basin characteristics. Acid-neutralizing capacity (ANC) of 151 lakes sampled during synoptic surveys and basin-characteristic information derived from geographic information system (GIS)...
