Field Season

The field work portion of our research on the biogeography of invertebrates and vascular plants has been completed. The geomorphological, bumble bee pollinator and plant community models developed during the first two field seasons worked well when applied to new sites in Dinosaur National Monument (DINO), Canyonlands National Park CANY), Arches National Park (ARCH), and Natural Bridges National Monument (NABR). Our research objectives for the 1993 field season were to: (1) complete the survey of plant and insect communities of hanging gardens in DINO, ARCH, CANY, and NABR; and (2) determine the geographic distribution of endemic species identified and the level of endemism within and among parks; and (3) complete the Halls Creek area survey for hanging gardens in Capitol Reef National Park (CARE).

AbstractBenthic animal communities in streams with varying environmental conditions in a national park in northern Swedish Lapland were analysed. Dominant taxa were Ephemeroptera, Plecoptera, Trichoptera and Diptera Simuliidae. Northeasterly or very widely spread species make up the fauna. Intrariverine distribution patterns were found to differ between taxa, and great variations of standing crop values between adjacent sampling sites were the rule. Day-to-day fluctuations of drift rate were unsynchronized between taxa. Some ecological properties of Brachyptera risi (Plec.) are discussed. Some lake shores and streams affected by hydroelectric exploitation appeared virtually devoid of macroscopic animals.

Hanging gardens are relatively small, isolated mesophytic communities surrounded by the xeric environment of canyon walls in the entrenched dendritic drainage pattern of the Colorado Plateau (Welsh 1989a, Malanson 1980, Welsh and Toft 1972). Various sandstone formations such as the NavaJo in Zion National Park serve as aquifers which produce permanent seeps or springs when underlain by impervious layers (Welsh and Toft 1972). These reliable sources of water and the associated processes of erosion and sedimentation, allow the formation of biotic communities that starkly contrast with the surrounding desert. Several endemic plant species have been found in Utah hanging garden surveys (Welsh 1989b, Loope 1977, Welsh and Toft 1972) and Dinosaur National Monument (T. Naumann, personal comm.). Virtually nothing is known about the invertebrate fauna. Our specific research objectives are to (1) survey the plant and invertebrate animal communities of hanging gardens in Zion National Park (ZION) and Glen Canyon National Recreation Area (GLCA), (2) map the geographic distribution of the endemics identified and determine levels of endemism within and among parks; (3) determine levels of similarity between each sampled hanging garden plant and insect community, and to (4) determine similarities among plant communities and among insect communities across gardens.

Insect Communities

Objectives 1) Determine the types of alterations in insect communities that invade fire-altered habitats; 2) Through comparison of burned and unburned areas, determine those species which are eliminated or reduced in numbers and those species that are added or increase in numbers due to the effects of the forest fires of 1988; and 3) From the impressions gained in field work associated with this project, recommend study directions for future entomological/ecological studies.

Abstract:We studied the effects of savanna fires on the structure of local ungulate communities in a West African woodland savanna. The distribution of 11 ungulate species over 9−15 burned sites (the number of which increased as burning activity continued during the dry season) and 7−13 unburned sites was compared with a variety of null models or randomized ‘virtual communities’. Five different parameters of community structure were examined: body mass distribution, co-occurrence patterns, species richness, species density and guild dominance. Overall, ungulate species were not randomly distributed over burned and unburned sites. The regular spacing of body masses in the set of species recorded on burned and unburned sites indicated competition, since species similar in body mass are more likely to compete than species of different size. However, co-occurrence patterns on burned sites were random, indicating absence of competition at fine spatial scales due to differential habitat use within the burned landscape. Although the attractiveness of the regrowth on burned sites resulted in higher numbers of ungulates compared with unburned sites, species richness was not different. Grazers were the dominant guild on burned sites, but there were no differences in species richness or species density between grazers and browsers on unburned sites.

Although the general ultrastructure of Cyanidium caldarium, an acidophilic, thermophilic alga of questionable taxonomic rank, has been extensively studied (see review of literature in reference 1), some peculiar ultrastructural features of the chloroplast of this alga have not been noted by other investigators.Cells were collected and prepared for thin sections at the Yellowstone National Park and were also grown in laboratory cultures (45-52°C; pH 2-5). Fixation (glutaraldehyde-osmium), dehydration (ethanol), and embedding (Epon 812) were accomplished by standard methods. Replicas of frozenfracture d- etched cells were obtained in a Balzers apparatus. In addition, cells were examined after disruption in a French Press.
