Spectral characterization of plant diversity in a biodiversity‐enriched oil palm plantation
1 Introduction Quantifying plant diversity using remote sensing has become a high priority for landscape management and conservation research, particularly in the context of biodiversity loss and the need for scalable monitoring tools (Asner, 2013; Draper et al., 2020; Roberts et al., 2022).
Plant beta-diversity across biomes captured by imaging spectroscopy - Nature Communications
Abstract Monitoring the rapid and extensive changes in plant species distributions occurring worldwide requires large-scale, continuous and repeated biodiversity assessments. Imaging spectrometers are at the core of novel spaceborne sensor fleets designed for this task, but the degree to which they can capture plant species composition and diversity across ecosystems has yet to be determined.
Ground-State Destabilization by Active-Site Hydrophobicity Controls the Selectivity of a Cofactor-Free Decarboxylase
Introduction Enzymatic catalysis of the formation and breaking of C–C bonds is currently receiving increasing attention.(1) In this context, enzymatic decarboxylation in particular has become highly attractive for the synthesis of optically pure building blocks(2) and the synthesis of alkenes(1,3−5) and alkanes from biobased precursors.(6) The release of gaseous CO2 renders decarboxylases quasi-irreversible, which has been exploited to drive numerous enzymatic cascade reactions.(7−11) In...

Partitioning plant spectral diversity into alpha and beta components
Abstract Plant spectral diversity – how plants differentially interact with solar radiation – is an integrator of plant chemical, structural, and taxonomic diversity that can be remotely sensed. We propose to measure spectral diversity as spectral variance, which allows the partitioning of the spectral diversity of a region, called spectral gamma (γ) diversity, into additive alpha (α; within communities) and beta (β; among communities) components.
