A comparison of behavior for two cohorts of captive-reared greater sandhill cranes released in northern Arizona A comparison of behavior for two cohorts of captive-reared greater sandhill cranes released in northern Arizona
To determine how the behavior of greater sandhill cranes (Grus canadensis tabida) changes according to time of year, time of day, and number of days after release, we observed the activities of 2 groups of captive-reared greater sandhill cranes at Mormon Lake, northern Arizona. The behaviors we compared were alert, loafing, sleeping, foraging, preening, locomotion, and other. We found...

Methods for estimating dispersal probabilities and related parameters using marked animals Methods for estimating dispersal probabilities and related parameters using marked animals
Deriving valid inferences about the causes and consequences of dispersal from empirical studies depends largely on our ability reliably to estimate parameters associated with dispersal. Here, we present a review of the methods available for estimating dispersal and related parameters using marked individuals. We emphasize methods that place dispersal in a probabilistic framework. In this

Effects of urbanization on the distribution of area-sensitive forest birds in Prince George's County, Maryland Effects of urbanization on the distribution of area-sensitive forest birds in Prince George's County, Maryland
Bird survey data from Prince George's County, Maryland, were used to evaluate the effects of urbanization on the distribution of forest bird species that are area sensitive. We developed models that predict the probability of occurrence for species during the nesting season as a function of forest area and degree of urbanization. All of the 21 bird species considered occurred in a higher

Snapping turtles (Chelydra serpentina) as monitors for mercury contamination of aquatic environments Snapping turtles (Chelydra serpentina) as monitors for mercury contamination of aquatic environments
We assessed the distribution of mercury in snapping turtles (Chelydra serpentina) by analyzing front shoulder muscle, back leg muscle, tail muscle, blood, liver, and marginal carapacial scute (shell) of 26 adult turtles from five small lakes. Total mercury concentration in muscle ranged from 50 to500 ng g−1 wet weight and was highly correlated among the three tissue locations. There was...

Suggestions for presenting the results of data analyses Suggestions for presenting the results of data analyses
We give suggestions for the presentation of research results from frequentist, information-theoretic, and Bayesian analysis paradigms, followed by several general suggestions. The information-theoretic and Bayesian methods offer alternative approaches to data analysis and inference compared to traditionally used methods. Guidance is lacking on the presentation of results under these...

Mercury contamination and growth rate two piscivore populations Mercury contamination and growth rate two piscivore populations
We found no relationship between fish growth rate and mercury concentration in a lake trout population and conditional support for an inverse relationship in a smallmouth bass population. A bioenergetics model indicated that mercury concentration was more responsive to dietary mercury intake than to growth rate. When biodilution is evident, it may bias contaminant versus fish size...

Fine-scale population structure Atlantic salmon from Maine's Penobscot River drainage Fine-scale population structure Atlantic salmon from Maine's Penobscot River drainage
We report a survey of microsatellite DNA variation in Atlantic salmon from the unimpounded lower reaches of Maine's Penobscot River. Our analysis indicates that Atlantic salmon in the Penobscot River are distinct from other populations that have little or no history of human-mediated repopulation, including two of its tributaries, Cove Brook and Kenduskeag Stream, another Maine river...
