Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

La energía en la formación de los suelos: aspectos teóricos y metodológicos para su evaluación Energy in soil formation: theoretical and methodological aspects for its evaluation

Ciencia del Suelo, 2008
El suelo es un sistema abierto que tiende hacia un equilibrio dinámico acumulando y reciclando materia y energía a través del tiempo. Mediante un balance energético es posible evaluar la energía acumulada o la que circula a través de su masa.

HOUSING RETROFIT AND THE JUST TRANSITION IN THE METROPOLIS: Governance, Redistribution, and Inequality in London and Barcelona

International Journal of Urban and Regional Research, EarlyView.
Abstract Metropolises are rapidly becoming spaces of stark inequalities. While much literature has emphasized the metropolitan scale as a driver of agglomeration economies, recent scholarship highlights either the ungovernable nature of large metropolises or the weak redistributive capacity of their governments as key causes of increasingly unequal ...

Responses of Soil Arthropod Communities to Varying Shading Levels in Agriphotovoltaic Systems

Integrative Zoology, EarlyView.
Soil fauna was primarily influenced by crop type and season rather than AgriPhotovoltaic (APV) panels. Elevated panels increased soil temperature and soil organic matter in early wheat stages, while shading enhanced soil moisture for tomatoes, benefiting moisture‐sensitive taxa.

Climate Change Commitment: As Agency Theory Pertains to Engaging Supply Chains in Science‐Based Targets

Accounting &Finance, EarlyView.
ABSTRACT We explore how corporates working towards valid Science‐based Targets engage with their suppliers to collect Scope 3 emissions data. This is important to enable such corporates to reduce greenhouse gas emissions and achieve net‐zero by 2050. Utilising agency theory, we analyse 1402 responses from the 2021 CDP climate change survey.
