Effects of removing woody cover on long-term population dynamics of a rare annual plant (): A study comparing remnant prairie and oldfield habitats.

Worldwide, grasslands are becoming shrublands/forests. In North America, eastern red cedar () often colonizes prairies. Habitat management can focus on woody removal, but we often lack long-term data on whether removal leads to population recovery of herbaceous plants without seeding.

Detection and plant monitoring programs: lessons from an intensive survey of Asclepias meadii with five observers.

Monitoring programs, where numbers of individuals are followed through time, are central to conservation. Although incomplete detection is expected with wildlife surveys, this topic is rarely considered with plants. However, if plants are missed in surveys, raw count data can lead to biased estimates of population abundance and vital rates.

Buffering and plasticity in vital rates of oldfield rodents.

1. Under the hypothesis of environmental buffering, populations are expected to minimize the variance of the most influential vital rates; however, this may not be a universal principle. Species with a life span <1 year may be less likely to exhibit buffering because of temporal or seasonal variability in vital rate sensitivities.

Density-dependent recruitment in grassland small mammals.

1. Density dependence has an important influence on the dynamics of many species of small mammals. To regulate population growth, density must affect negatively a vital rate (e.
