Improving impervious surface estimation: an integrated method of classification and regression trees (CART) and linear spectral mixture analysis (LSMA) based on error analysis

GIScience & Remote Sensing, 2018
Classification and regression tree (CART) has been widely implemented to estimate impervious surface, an important indicator of urbanization and environmental quality.

The Impacts of the Expansion of Urban Impervious Surfaces on Urban Heat Islands in a Coastal City in China

, 2020
The effect of the expansion of urban impervious surfaces on surface urban heat islands (UHIs) has attracted research attention due to its relevance for studies of local climatic change and habitat comfort.

Beyond first clutches: Second broods reshape selection on breeding timing in forest and urban great tits

Journal of Animal Ecology, EarlyView.
Most studies of selection on breeding timing consider only first clutches. Using a 13‐year dataset of urban and forest great tits, we show that including second broods reshapes estimates of natural selection, revealing that early breeding is favoured through increased probability of multiple brooding and higher annual reproductive output.

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

Integrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Using Impervious Surfaces to Detect Urban Expansion in Beijing of China in 2000s

, 2016
The change of impervious surface area (ISA) can effectively reveal the gradual process of urbanization and act as a key index for monitoring urban expansion.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Impervious Surface Area Patterns and Their Response to Land Surface Temperature Mechanism in Urban–Rural Regions of Qingdao, China

, 2023
The expansion of impervious surface area (ISA) in megacities of China often leads to land surface temperature (LST) aggregation effects, which affect living environments by impacting thermal comfort levels, thus becoming an issue of public concern ...

Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...
