Abstract Purpose Although plant functional type can modulate soils and their processes in natural, nitrogen (N)-limited ecosystems, little is known about ability to influence soil N dynamics urban ecosystems that have high excess input. We investigated whether i) effects on parks follow the same pattern as those undisturbed natural/semi-natural forests, ii) park age influences under boreal clim...

Park availability and land use diversity (LUD) are independent environmental correlates of physical activity (PA). This paper investigated whether parks were more likely to be used for PA if surrounded by greater LUD, as well as the interaction of LUD with the number of facilities in the park for predicting use of the park for PA. Facilities in 32 parks from 4 neighborhoods were audited and LUD...

The cooling effects of urban parks, which form “Park Cool Island” (PCI), can help decrease land surface temperature (LST) and mitigate urban heat island (UHI) effects. PCI intensity largely depends on the characteristics of urban parks. The relationship between PCI intensity and urban park characteristics such as urban park size has been well documented. However, it is still unclear how urban f...

The importance of natural disturbances for biodiversity is well-documented in the disturbance ecology literature. Natural such as fire, wind, and flooding strongly influence ecosystems by creating short long-term ecological processes. Conservation management protected areas should consider since shifts are, a perspective, necessary to maintain high biodiversity. purpose this study explore how i...
