Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...

Synergistic Sr2+ Doping and MXene Engineering of Layered δ‐MnO2 Toward High‐Performance Aqueous Zinc‐Ion Batteries

Small, EarlyView.
Sr‐doped δ‐MnO2/Nb2C composites are engineered for aqueous zinc‐ion batteries, utilizing Sr2+ doping and conductive Nb2C to enhance structural stability and ion transport. The optimized cathode delivers a 407.3 mAh g−1 capacity and excellent cycling, driven by a reversible Zn2+/H+ co‐insertion mechanism, making it suitable for flexible electronics ...

Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

Small, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

The Sea Urchin Diadema antillarum (Echinodermata, Equinoidea), algal cover and juvenile coral densities in La Parguera, Puerto Rico

Cuadernos de investigación UNED, 2013
Grazing by the black sea urchin Diadema antillarum reduces algal cover and enhances coral recruitment. The overall goal of this project was to examine if there is a relationship between densities of D.

Beggars as Rational Choosers

Southern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...

Local Eviction Moratoria and the Spread of COVID‐19

Southern Economic Journal, EarlyView.
ABSTRACT At different stages during the initial onset of the COVID‐19 pandemic, various US states and local municipalities enacted eviction moratoria. One of the main aims of these moratoria was to slow the spread of COVID‐19 infections. We deploy a semiparametric difference‐in‐differences approach with an event study specification to examine whether ...

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

Structural Concrete, EarlyView.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Development of a coral and competitive alga-related index using historical multi-spectral satellite imagery to assess ecological status of coral reefs

International Journal of Applied Earth Observations and Geoinformation
Understanding the characteristics of the growth zones of live corals and competitive algae, including turf algae and macroalgae, is crucial for assessing the degradation of coral reef ecosystems.

Social organization and habitat use shape the gut microbiome of a marine fish

Journal of Animal Ecology, EarlyView.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.
