Ocean acidification at the crossroads I: Harmonizing unpurified and purified meta‐cresol purple spectrophotometric pHT measurements based on absorbance data

Limnology and Oceanography: Methods, EarlyView.
Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

Oikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

Oikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.
