Landscape associations of frog and toad species in Iowa and Wisconsin, U.S.A Landscape associations of frog and toad species in Iowa and Wisconsin, U.S.A
Landscape habitat associations of frogs and toads in Iowa and Wisconsin were tested to determine whether they support or refute previous general habitat classifications. We examined which Midwestern species shared similar habitats to see if these associations were consistent across large geographic areas (states). Rana sylvatica (wood frog), Hyla versicolor (eastern gray treefrog)...

Managing wetlands for waterbirds: How managers can make a difference in improving habitat to support a North American Bird Conservation Plan Managing wetlands for waterbirds: How managers can make a difference in improving habitat to support a North American Bird Conservation Plan
Wetlands are the most productive ecosystems in the world, yet they have suffered more loss and degradation than any other ecosystem. Not surprisingly, 50% (29 of 58) of all the bird species in the U. S. (excluding Hawaii and territories) that are listed either as federally threatened or endangered, or are on the U. S. Fish & Wildlife Service 1995 List of Migratory Nongame Birds of...

Microsatellites: Evolutionary and methodological background and empirical applications at individual, population, and phylogenetic levels Microsatellites: Evolutionary and methodological background and empirical applications at individual, population, and phylogenetic levels
The recent proliferation and greater accessibility of molecular genetic markers has led to a growing appreciation of the ecological and evolutionary inferences that can be drawn from molecular characterizations of individuals and populations (Burke et al. 1992, Avise 1994). Different techniques have the ability to target DNA sequences which have different patterns of inheritance...

Microscopic functional anatomy: Integumentary system: Chapter 17 Microscopic functional anatomy: Integumentary system: Chapter 17
Many of the features of the fish integument can only be observed microscopically. Because there are over 20,000 living fishes, mostly higher bony fishes (teleosts), a great diversity exists in the microscopic anatomy of the integument. This chapter presents several examples from varied taxonomic groups to illustrate the variation in morphological features. As in all vertebrate epidermis...

Modeling the distribution of neotropical birds throughout the Americas Modeling the distribution of neotropical birds throughout the Americas
I assessed tbe geographic information system (GIS) model and data layers used to create individual Neotropical bird species distribution maps from habitat data contained in the Ecological and Distributional Databases in 'Neotropical Birds: Ecology and Conservation' by D.F. Stotz, J.W. Fitzpatrick, T.A. Parker Ill, and D.K. Moskovits.
