A Survey of the Fishes and Habitat of the Cheyenne River in South Dakota
… only a few locations and did not record any habitat or species abundance data. I sampled fish and habitat at nine reaches between Angostura Dam and Lake Oahe on the mainstem Cheyenne River during the summer months of 1996 and 1997. Thirty species representing ten families were collected. The …

Examination and management of human African Trypanosomiasis propagation using geospatial techniques
… factors, and understanding the vector’s habitat is vital to its control. There is no HAT vaccine, but biological control of the vector has been successful in reducing HAT incidence. However, in recent years the disease has re-emerged and spread. Due to insufficient knowledge of HAT …

The Foraging Ecology, Habitat Use, and Population Dynamics of the Laysan teal (Anas laysanensis)
… ecology, therefore, I examined food habits, habitat use, and population dynamics. These aspects of its ecology are fundamental to the species management and conservation. I described diel and nocturnal habitat use, home range, and foraging with radio telemetry in 1998-2000. Most individuals …

Geochemical controls on production and transport of methylmercury in the St. Louis River Estuary
… sources. The estimated MeHg loading from habitat zones represented by the three sites included in this study (45% of total estuary area) contributed a small amount MeHg to overlying water relative to upstream sources during low, median, and high flow conditions.

Wave energy and the role of swimming in reef fish ecology
… levels of wave-induced water motion among reef habitats with the swimming mode and performance of resident reef fishes. Encompassing ten families (Acanthuridae, Chaetodontidae, Labridae, Lutjanidae, Nemipteridae, Pomacanthidae, Pomacentridae, Serranidae, Siganidae and Zanclidae), the generality …

Influence of habitat complexity on diversity and community structure of arboreal spiders in grassland-shrub systems
… In grasslands, much of the arboreal habitat is in the form of shrubs, but the role and importance of shrubs in distribution and diversity of arthropods in grasslands is unknown. Spiders are a useful indicator for examining the role of shrubs in arthropod ecology because they are …

Smelt (Retropinna retropinna) population dynamics and predation by rainbow trout (Salmo gairdneri) in Lake Taupo
… was used to predict the effects of variation in habitat features on smelt population processes and on their consumption by trout. Implications for fisheries management are discussed. The smelt population was comprised of three year classes. The juvenile 0+ year class occupied only the pelagic …
