Optical Diversity and Nanostructural Organization in the Colored Scales of Sternotomis

open access: yesAdvanced Optical Materials, EarlyView.
Vivid colors in Sternotomis beetles originate from nanoscale photonic architectures embedded within individual scales. Here, we provide a comparative optical and structural analysis of 57 scale types that reveal how ordered, quasi‐ordered, and disordered 3D networks tune color, saturation, and angular response.

Rare earth elements as tracers of chemical transfer processes in tropical rain forest soils in french Guiana : S13.04-P -10 [PDF]

open access: yes, 2012
The rare earth elements (REE) have been successfully used in the past to trace weathering and water/rock interaction in lateritic soil systems. In the present study we used the REE to monitor chemical transfer processes in French Guiana along a ...

The Osteoblastic Microenvironment Determines the Fate of Breast Cancer Cells Disseminated in the Bone Marrow

open access: yesAdvanced Science, EarlyView.
This study revealed how the osteoblastic microenvironment determines the fate of cancer cells disseminated in bone, with a focus on whether they colonize, reside in quiescence, or reactivate from dormancy. Targeting integrin signaling may offer promising strategies for preventing quiescent cancer cells reactivation and bone colonization.

Influence of induced cementation on compressibility and shear behaviour of tropical residual soils

open access: yesJournal of Asian Architecture and Building Engineering
The analysis and prediction of the behavior of sedimented soils are fairly well established and widely accepted. The behavior of tropical residual soils is different from that of sedimented soils owing to the basic differences that exist in the formation

Global assessment of nitrogen deposition effects on terrestrial plant diversity : a synthesis [PDF]

open access: yes, 2009
Atmospheric nitrogen (N) deposition is it recognized threat to plant diversity ill temperate and northern parts of Europe and North America. This paper assesses evidence from field experiments for N deposition effects and thresholds for terrestrial plant

Coupled Above‐ and Belowground Ecosystem Stability Worldwide

open access: yesAdvanced Science, EarlyView.
Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

Meta-analysis on how manure application changes soil organic carbon storage

open access: yesScientific Reports, 2021
Manure application to agricultural soils is widely considered as a source of nutrients and a method of maintaining levels of soil organic carbon (SOC) to mitigate climate change.

Climate Change Agricultural Comparative Advantage and the US Trade Balance

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

Elevated CO2 does not increase eucalypt forest productivity on a low-phosphorus soil [PDF]

open access: yes, 2017
Rising atmospheric CO2 stimulates photosynthesis and productivity of forests, offsetting CO2 emissions. Elevated CO2 experiments in temperate planted forests yielded ~23% increases in productivity over the initial years.

Do outgrower schemes enhance technology adoption and productivity? Evidence from maize farmers in Northern Ghana

open access: yesAgribusiness, EarlyView.
Abstract Nucleus outgrower schemes are contractual arrangements where well‐resourced large‐scale farmers (nucleus farmers) are empowered by development support agencies to take charge of smallholder farmers, by providing them with market access and the necessary training on agronomic practices and farm inputs for production.
