Role of lake-wide prey fish survey in understanding ecosystem dynamics and managing fisheries of Lake Michigan Role of lake-wide prey fish survey in understanding ecosystem dynamics and managing fisheries of Lake Michigan
With this study, the role of this lake-wide prey fish survey in both understanding the dynamics of the Lake Michigan ecosystem and managing Lake Michigan fisheries was documented. The complexity of ecosystems is such that long-term study is required before the dynamics of the ecosystem can be understoond. Furthermore, long-term observation is needed before important or meaningful...

Setting limits: The development and use of factor-ceiling distributions for an urban assessment using macroinvertebrates Setting limits: The development and use of factor-ceiling distributions for an urban assessment using macroinvertebrates
Lotic habitats in urban settings are often more modified than in other anthropogenically influenced areas. The extent, degree, and permanency of these modifications compromise the use of traditional reference-based study designs to evaluate the level of lotic impairment and establish restoration goals. Directly relating biological responses to the combined effects of urbanization is...

Size evolution in Goodwin’s small-eared shrew, Cryptotis goodwini Size evolution in Goodwin’s small-eared shrew, Cryptotis goodwini
Fossils of Cryptotis goodwini from Honduras indicate that body sizes of modern individuals average at least 18% larger than among members of the late Pleistocene population of this species. Palynological and other paleoenvironmental studies provide evidence that the Neotropical montane environments that these shrews inhabit were cooler and drier in the late Pleistocene than at present...

Statistical approaches to the analysis of point count data: A little extra information can go a long way Statistical approaches to the analysis of point count data: A little extra information can go a long way
Point counts are a standard sampling procedure for many bird species, but lingering concerns still exist about the quality of information produced from the method. It is well known that variation in observer ability and environmental conditions can influence the detection probability of birds in point counts, but many biologists have been reluctant to abandon point counts in favor of...

Status and conservation of the fish fauna of the Alabama River system Status and conservation of the fish fauna of the Alabama River system
The Alabama River system, comprising the Alabama, Coosa, and Tallapoosa subsystems, forms the eastern portion of the Mobile River drainage. Physiographic diversity and geologic history have fostered development in the Alabama River system of globally significant levels of aquatic faunal diversity and endemism. At least 184 fishes are native to the system, including at least 33 endemic...

Testing a West Nile virus vaccine in sandhill cranes (Grus canadensis) Testing a West Nile virus vaccine in sandhill cranes (Grus canadensis)
Eight sandhill cranes (Grus canadensis) were vaccinated with a commercial equine West Nile virus vaccine (Fort Dodge Animal Health, Fort Dodge, Iowa, USA) at the USGS Patuxent Wildlife Research Center, Laurel, Maryland, USA. Three doses of the vaccine were given, the first dose (day 0) was followed by a second 21 days later and the third dose 7 days after the second day 28 after the...
