The cercaria of Bucephalus minimus infects the digestive gland and gonads of its first intermediate host, the edible cockle, Cerastoderma edule. Light microscopy (LM) and scanning electron microscopy (SEM) of the cercaria showed a tail formed by a central stem, with 2 long contractile arms presenting distinct morphological surfaces. The encysted metacercaria naturally infected the flathead grey...

PURPOSE To depict the phenomenon of nursing in the Native American culture. DESIGN At the 1997 annual Native American Nursing Summit held on the Flathead Reservation in Montana, 203 Native American nurses, nursing students, and others who provide health care to Native American people attended and participated in focus groups that provided the data for this qualitative study. The participants ...

Sound of Rivers: Stone Drum is a multimedia collaboration, between choreographer Nicole Bradley Browning, animator and video artist Amber Marjorie Bushnell, poet and narrator Mark Gibbons, and composer and electric violinist Charles Nichols, with dancer Allison Herther and narrator Stephen Kalm. The piece illuminates research by scientist Mark Lorang, into how fish and insects navigate the ecos...

In Tunisia, mugilid and soleid fish species are among the most important resources of the Tunisian lagoons. These fish are of great economic value and they are highly valued for their flesh. Some species of mullet from Tunisian waters, especially Mugil cephalus and Liza ramada, have been found to be infected with several myxosporean species, all of which belonging to the genus Myxobolus Bütschl...

During the summer of 1969, six portable seismographs were operated at 82 sites along the Intermountain Seismic Belt from southwestern Utah to northwestern Montana. This survey followed a well-known seismic belt along the eastern physiographic boundary of the Basin and Range province, and within the middle and northern Rocky Mountains. In general, the 120 microearthquakes located in this study f...

Introductions or invasions of nonnative organisms can mediate major changes in the trophic structure of aquatic ecosystems. Here we document multitrophic level impacts in a spatially extensive system that played out over more than a century. Positive interactions among exotic vertebrate and invertebrate predators caused a substantial and abrupt shift in community composition resulting in a trop...

Trichodinid Ciliophorans are one of the most common and widely dispersed groups of symbionts as parasites of aquatic invertebrate and vertebrate hosts (VAN AS & BASSON, 1989). The taxonomy of Trichodinids is based on the structure and the appearance of the adhesive disc and number and size of its constituents. All of these features can be revealed only by the silver impregnation technique of Kl...

Frequentist statistics is not well adapted to handling uncertainties inherent in managing natural resources. A frequentist approach typically involves estimating unknown parameters of ecosystem relationships and testing their statistical significance. While such information is useful, natural resource managers have a greater need to know the most likely current state of an ecosystem and whether...
