The one-by-one method for releasing cranes The one-by-one method for releasing cranes
Although the trend for the past 2 decades has been toward releasing naive groups of juveniles after a lengthy acclimation period, in 5 separate releases (1996-2000) we tested the idea that naive juvenile greater sandhill cranes (Grus canadensis tabida) would survive better if released singly into a wild flock of predator-wary birds than if left as a group, inexperienced at foraging and...

The robust design for capture-recapture studies: analysis using program MARK The robust design for capture-recapture studies: analysis using program MARK
Collecting capture-recapture data under Pollock?s robust design provides an additional source of information on capture probability that can be used to provide less biased and more efficient estimates of population dynamics parameters. In addition, it can be used to estimate the probability of being available for capture, which in some cases (e.g., breeding proportion) has ecological...

Tracking sandhill crane migration from Saskatchewan to the Gulf Coast Tracking sandhill crane migration from Saskatchewan to the Gulf Coast
Four adult sandhill cranes (Grus canadensis rowani) were captured in east-central Saskatchewan, equipped with transmitters, and tracked by satellite to determine if their migration routes and wintering areas would allow their use as guide birds to establish a new migratory flock of whooping cranes (G. americana). Two birds captured near Yorkton died or their transmitters were lost before

Type characters of non-native plant species in Great Lakes national parks (USA) Type characters of non-native plant species in Great Lakes national parks (USA)
Non-native plant species are increasing in frequency and abundance in many natural areas in the United States. In Midwestern National Parks, as much as one third of the flora may be non-native. It was hypothesized that botanical characters of these species could be used to typify them and improve the methods of predicting invasions. Data on 19 characters of 341 non-native species from...

Uncertainty and spatial linear models for ecological data Uncertainty and spatial linear models for ecological data
Models are not perfect; they do not fit the data exactly and they do not allow exact prediction. Given that models are imperfect, we need to assess the uncertainties in the fits of the models and their ability to predict new outcomes. The goals of building models for scientific problems include (1) understanding and developing appropriate relationships between variables, and (2)...
