Influence of trace metal additions on the longevity of algal blooms across a productivity gradient

open access: yesJournal of Phycology, EarlyView.
Abstract Phytoplankton require specific nutrients in varying quantities for growth, defense, and proper cell functioning. When macronutrients are present in excess, trace metals can exhibit co‐limitation on phytoplankton. This experiment aimed to understand how ambient nutrient concentrations impact phytoplankton community persistence (i.e., bloom ...

Are We Witnessing a Speciation Continuum? Evidence From Current and Past Gene Flow in the Genus Oritrophium s.s. (Asteraceae) From the Tropical High Andes

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Determining species boundaries is key for appropriately assessing biodiversity. However, the continuity of the speciation process makes delimiting species a difficult task, especially for recently diverged taxa. Furthermore, past introgression may leave traces that result in reticulate evolutionary patterns, challenging the estimation of ...

Structural determinants for red‐shifted absorption in higher‐plants Photosystem I

open access: yesNew Phytologist, EarlyView.
Summary Higher plants Photosystem I absorbs far‐red light, enriched under vegetation canopies, through long‐wavelength Chls to enhance photon capture. Far‐red absorption originates from Chl pairs within the Lhca3 and Lhca4 subunits of the LHCI antenna, known as the ‘red cluster’, including Chls a603 and a609.
