Variations in Sexual Size Dimorphism in Two Anurans Along an Urbanization Gradient in Shanghai: Assessment of Rensch's Rule

Ecology and Evolution, Volume 16, Issue 6, June 2026.
ABSTRACT Variations in sexual size dimorphism (SSD) have important consequences for animal ecology, behavior, population dynamics, and the evolution of life‐history traits, and can be explained by many intraspecific and interpopulation hypotheses. Urbanization is an important factor that affects anuran phenotypic characteristics (including morphology),

Discriminant Analysis with Spatial Weights for Urban Land Cover Classification [PDF]

Classifying urban area images is challenging because of the heterogeneous nature of the urban landscape resulting in mixed pixels and classes with highly variable spectral ranges. Approaches using ancillary data, such as knowledge based or expert systems,

Determinants of Bird Richness in the Louzishan National Nature Reserve: Effects of Productivity and Habitat Heterogeneity Across Taxonomic and Functional Dimensions

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We want to reveal the relationship between the alpha and beta diversity of birds and its two components with vegetation productivity and habitat heterogeneity from both taxonomic and functional perspectives. Our findings reveal productivity, as an important environmental variable, influences bird species richness and compositional differences from two ...

Impact of Multidimensional Urban Expansion on Thermal Environment Supported by Refined Population Spatial Distribution in Pearl River Delta

ISPRS International Journal of Geo-Information
The urban heat island effect, a typical rapid urbanization issue, arises from natural surfaces covered by impermeable layers via urban sprawl.

Extraction of Urban Impervious Surface Using Two-Season WorldView-2 Images: A Comparison

, 2016
Although multispectral images acquired during the summer season have been used extensively in impervious surface extraction with relatively high accuracy, the area of impervious surface extracted is generally underestimated. In this study, a quantitative

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients

Ecography, Volume 2026, Issue 6, June 2026.
Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.

A sub-meter resolution urban surface albedo dataset for 34 U.S. cities based on deep learning

Scientific Data
Surface albedo is a key determinant of urban heat islands, which modulates the amount of solar energy absorbed or reflected by urban surfaces, influencing microclimate and thermal comfort.

EXTRACTION OF URBAN IMPERVIOUS SURFACE FROM MULTI-TEMPORAL WORLDVIEW-2 IMAGERY USING SPECTRAL MIXTURE ANALYSIS: A COMPARATIVE STUDY

, 2015
Impervious surface is considered as a key indicator of urban environment quality and urbanization. Many studies have attempted to extract urban impervious surface using multispectral images of medium and high resolution, especially images acquired in ...

Modeling Land Management Impacts: Asymmetric Reductions of Sediment and Phosphorus Versus Legacy Nitrogen in the Enkare Narok Catchment in Kenya

Engineering Reports, Volume 8, Issue 6, June 2026.
Conservation practices in an East African catchment dramatically cut sediment (80%) and phosphorus (76%) loads but are markedly less effective on nitrogen (8% reduction) due to legacy groundwater nitrate, revealing a critical trade‐off between water quality and quantity.

Concrete Habitat Severely Decreases the Reproductive Output of Two Urban Birds

Conservation Letters
The conversion of natural habitats to impervious surfaces in cities affects biotic and abiotic attributes of urban ecosystems. However, detailed information on the gradual influence of impervious surfaces on reproductive output is lacking.
