Monitoring changes in the impervious surfaces of urban functional zones using multisource remote sensing data: a case study of Tianjin, China

open access: yesGIScience & Remote Sensing, 2019
Previous research on urban impervious surface monitoring has ignored the differences, spatial patterns, and driving factors of impervious surfaces among the various functional zones in cities.

A Scheme for the Long-Term Monitoring of Impervious−Relevant Land Disturbances Using High Frequency Landsat Archives and the Google Earth Engine

open access: yesRemote Sensing, 2019
Impervious surfaces are commonly acknowledged as major components of human settlements. The expansion of impervious surfaces could lead to a series of human−dominated environmental and ecological issues.

Using wingbeat frequency to estimate mass gain

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Energy intake is a fundamental currency in ecology that is critical to reproductive success, survival and lifetime fitness. Measuring foraging success in wild animals via biologgers has been a long‐standing challenge but is essential to understanding the mechanisms underlying population dynamics and species distributions.

Impervious Surface Change Mapping with an Uncertainty-Based Spatial-Temporal Consistency Model: A Case Study in Wuhan City Using Landsat Time-Series Datasets from 1987 to 2016

open access: yesRemote Sensing, 2017
Detailed information on the spatial-temporal change of impervious surfaces is important for quantifying the effects of rapid urbanization. Free access of the Landsat archive provides new opportunities for impervious surface mapping with fine spatial and ...

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

open access: yesAmerican 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 ...

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation 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 ...

A robust method for mapping refugial capacity in montane forests

open access: yesConservation Science and Practice, EarlyView.
We developed a refugial capacity analysis to guide management strategies to protect montane forests that will be relatively buffered from disturbances. Through sensitivity analyses, we found that our approach was robust to uncertainty in thresholds and climate forecasts, consistently identifying refugia across the landscape in similar locations and ...

Evaluation of impervious surface extraction based on Qimingxing-1 nighttime light and point of interest data

open access: yesInternational Journal of Digital Earth
Impervious surface extraction is essential for environmental management and urban studies. Although nighttime light data have been widely used for this purpose, few studies have utilized the high-resolution (21 m) Qimingxing-1 data released in 2022 ...

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

open access: yesEcological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...
