Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics
Global Change Biology, Volume 29, Issue 2, Page 308-323, January 2023., 2023 Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...
