Peter Ibsen, PhD
Peter is Research Ecologist working at the Geosciences and Environmental Change Science Center in Denver, Colorado.
Peter is trained as a Botanist and Ecologist, and calls himself an Urban Ecologist. His research examines the how interactions of climate and land cover change within urban ecosystems influences the quantification, and resulting valuation, of ecosystem services. He specializes in the modelling and mapping of extreme urban heat at microscales within cities, analyzing climate and land use drivers of monarch abundances, and the integration of in-situ low-cost sensor data and high-resolution land cover data though multivariate analysis and machine learning models.

Reducing Wildfire Risk While Maintaining Critical Monarch Habitat Along the California Coast
The California Coast has hundreds of tree groves where dual management practices aim to reduce the risk of fire and to conserve habitat for overwintering monarch butterflies. As the climate changes, longer high-intensity droughts can increase mortality and/or limb loss in grove trees which causes an accumulation of fire-prone fuels. Moreover, these trees provide the critical habitat for overwinterLand Change Science
Land cover change is one of the fundamental measures for understanding pressures on ecosystems and is widely used to understand the consequences to biodiversity and ecosystem services. This study utilizes land cover and other associated socioeconomic and environmental data to examine the consequences of land cover change in human-dominated landscapes, and how provisioning of ecosystem services... - Data
Urban landcover differentially drives day and nighttime air temperature across a semi-arid city
Semi-arid urban environments are undergoing an increase in air temperatures, both in average temperatures and in the frequency and intensity of extreme heat events. Within cities, different varieties of urban landcovers (ULC) and their densities influence local air temperatures, either mitigating or increasing heat. Currently, understanding how various combinations of ULCs influence air temperatur - Multimedia

Limited role of absolute humidity in intraurban heat variability
Monitoring and understanding the variability of heat within cities is important for urban planning and public health, and the number of studies measuring intraurban temperature variability is growing. Recognizing that the physiological effects of heat depend on humidity as well as temperature, measurement campaigns have included measurements of relative humidity alongside temperature.
