Abstract Increasing urbanization in the United States presents new challenges and opportunities for wildlife species. One species that is thought to benefit from urbanization is Didelphis virginiana (Virginia Opossum). We used radio-telemetry to determine home-range size of opossums living in an urban area and compared body mass measurements of urban and rural animals to ascertain how urbanization affects this parameter for opossums. Minimum convex polygon estimates for male (37.3 ± 46.0 ha; n… 

An Artificial Waterway and Road Restrict Movements and Alter Home Ranges of Endangered Arboreal Marsupial

Artificial linear structures can cause habitat fragmentation by restricting movements of animals and altering home ranges. The negative impacts of these linear structures, especially of those other

Virginia opossum distributions are influenced by human-modified landscapes and water availability in tallgrass prairies

The Flint Hills represent the largest tract of tallgrass prairie in North America and is located near the western edge of the native range of the Virginia opossum (Didelphis virginiana). This region

Effect of urbanization on the opossum Didelphis virginiana health and implications for zoonotic diseases

Reducing the impermeable areas in city planning is recommended to contribute to a better health of the urban animals and therefore reduce risks of zoonotic diseases with potentially disastrous results.

Urban mesopredator distribution: examining the relative effects of landscape and socioeconomic factors

Cities harbor biodiversity, which has complex outcomes, both for humans and other animals. The situation is particularly complicated with carnivorous species such as mesopredators, which elicit

Investigation of the Northern Range Expansion of the Virginia Opossum (Didelphis virginians)

IMPETUS METHODS Climate: • NOAA and NCRS databases were searched for weather stations within our target area (Fig. 4) • Long-term daily temperature data from 1900-2010 were downloaded • Average

FOOD SELECTION AND USE OF SPACE BY DIDELPHIS PERNIGRA (DIDELPHIDAE: MAMMALIA) IN AN ANDEAN SUBURBAN ENVIRONMENT

Although the opossums need resources associated with natural environments, the results suggest that there are human modifications that can benefit them, such as those that reduce the risk of predation and favor their mobility in suburban environments.

Genetic diversity of Didelphis virginiana related to different levels of disturbance in the Highlands and the Central Depression regions of Chiapas, Mexico

The genetic diversity of D. virginiana at sites with different levels of disturbance within the Highlands and Central Depression regions of Chiapas in southern Mexico is evaluated to observe low but significant levels of genetic differentiation according to disturbance level.

Seasonal Movements and Habitat Use of Female White-Tailed Deer Associated with an Urban Park

Deer management programs developed for urban communities should consider movement patterns of deer to ensure the most effective control of particular nuisance individuals, and suggest that a major difference between urban and rural deer is in spatial scale.

Demographic factors contributing to high raccoon densities in urban landscapes

The data suggest that multiple factors, including increased survival, higher annual recruitment, and increased site fidelity, are jointly responsible for high-density raccoon populations in urbanized areas.

What free-ranging animals do at the zoo: a study of the behavior and habitat use of opossums (Didelphis virginiana) on the grounds of the St. Louis Zoo

It is found that urban opossums in the St. Louis zoo have smaller home ranges and move shorter distances than their rural counterparts, and it is suspected that conditions are even more favorable to opossum in a zoological setting than in cities in general.
