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 ...

Journal of Animal Ecology, EarlyView.This study provides new insights into how ecological conditions influence the evolution of host‐associated symbiotic communities and their functional roles. The findings suggest that pathogen pressures linked to nesting habits in birds shape bacterial communities of the uropygial gland, and their connection with the skin microbiome, where the ...

Journal of Animal Ecology, EarlyView.We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Insect Science, EarlyView.Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐
