Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics

open access: yesGlobal 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 ...

Local environment and sampling bias drive parasite prevalence estimates in freshwater fish communities

open access: yesOikos, EarlyView.
Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,

Analysis of Interactions Between Pyomelanin and the Extracellular Matrix in an Ex Vivo Turkey Tendon Model

open access: yesChemistryOpen, EarlyView.
Polymerization of homogentisic acid in the presence of extracellular matrix (ECM) components (an ex vivo turkey tendon model) yields simplified versions of biologically generated melanins in the ECM, facilitating studies of melanin–ECM interactions. A variety of techniques (X‐ray diffraction, microscopy, and spectroscopy) were employed to understand ...
