Seasonal Environmental Conditions and River Morphology Shape Summer Phytoplankton Communities

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Phytoplankton form the base of large river food webs, but there are limited studies on the nature and drivers of communities over longer time scales. Further, climate change is projected to favour taxa associated with harmful algal blooms, but our knowledge of the timing, locations and drivers of cyanobacteria in rivers lags that of lakes and ...

The Separate Roles of Vascular Plants and Sphagnum Mosses in Regulating the Net CO2 Exchange in a Boreal Peatland During Key Phenological Phases

Global Change Biology, Volume 32, Issue 4, April 2026.
In this study, we disentangle the roles of plant functional groups in regulating CO2 production and respiration fluxes across key phenophases using automated chamber measurements in a boreal peatland. Sphagnum mosses dominate gross primary production (GPP) during green‐up and senescence, while vascular plants prevail during the peak season.

Historic disturbance events overruled climatic factors as drivers of ruderal species distributions in the Scandinavian mountains

Nordic Journal of Botany, Volume 2026, Issue 4, April 2026.
The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden.

PEP725: 15 years of driving European and global phenology science

New Phytologist, Volume 250, Issue 2, Page 717-734, April 2026.
Summary Phenology – the timing of seasonal biological events – is a sensitive indicator of climate change and ecosystem dynamics. Long‐term, broad‐scale phenological data are crucial for understanding and predicting plant responses to environmental change.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Biochemical phosphorus allocation is linked to photosynthetic phosphorus‐use efficiency in a phosphorus‐impoverished environment

New Phytologist, Volume 250, Issue 2, Page 905-920, April 2026.
Summary Highly efficient phosphorus (P)‐use strategies have evolved in plants, allowing them to thrive in severely P‐impoverished environments. However, it remains unclear how allocating leaf P to biochemical fractions, including specific P‐containing metabolites, contributes to instantaneous photosynthetic P‐use efficiency (iPPUE) and the position of ...
