Online now: 3D tracking of marine megafauna to advance movement ecology
dlvr.it
3D tracking of marine megafauna to advance movement ecology
Modern animal tracking devices reliably record movement in horizontal and vertical dimensions, positioning movement ecology to transition towards true three-dimensional (3D) analyses. True 3D tracking, in which horizontal and vertical positions are paired through time, is particularly valuable for marine megafauna, which traverse coastal, pelagic, and aerial environments, making them ideal for illustrating how 3D data can advance movement ecology. By synthesising early approaches to 3D tracking in these taxa, we show that these studies provide ecological perspectives unobtainable from two-dimensional data, identify key barriers limiting wider adoption, and highlight emerging solutions. Broader adoption of true 3D tracking is critical for addressing remaining knowledge gaps in marine megafauna ecology and for improving conservation frameworks to protect the 3D environments these species occupy.

Online now: Rethinking plasticity in fungal resilience and ecosystem functioning
dlvr.it
Rethinking plasticity in fungal resilience and ecosystem functioning
Fungi are widely recognized as phenotypically plastic, a characteristic often invoked to explain the persistence of ecosystem functions under disturbance. How plasticity varies across taxa remains a key question. Emerging evidence implies species-specific, phylogenetically structured responses, with the strongest divergence under environmental extremes, making fungal community composition essential to ecosystem functioning.

Synthetic communities of maize root bacteria interact and redirect benzoxazinoid metabolization
Plant roots are colonized by diverse microbial communities. These communities are shaped by root exudates, including plant-specialized metabolites. Benzoxazinoids are such secreted compounds of maize. Individual microbes differ in their ability to tolerate and metabolize antimicrobial benzoxazinoids. To investigate how these traits combine in a community, we designed two synthetic communities of maize root bacteria that share six common strains and differ in their ability to metabolize benzoxazinoids based on the seventh strain. We exposed both communities to the benzoxazinoid MBOA (6-methoxybenzoxazolin-2(3H)-one) in vitro and found that the metabolizing community did not degrade MBOA to its aminophenoxazinone, as observed for individual strains, but, as a community, they formed the corresponding acetamide. MBOA shaped the differential compositions of both communities and increased the fraction of MBOA-tolerant strains. The benzoxazinoid-metabolizing community showed a higher tolerance to MBOA and was able to utilize MBOA as their sole carbon source for growth. Hence, bacterial interaction results in alternative benzoxazinoid metabolization and increases community performance in the presence of these antimicrobial compounds. Future work is needed to uncover the genetics of this metabolic interaction and ecological consequences for the bacterial community and the host plant.
