Climate change is associated with higher phytoplankton biomass and longer blooms in the West Antarctic Peninsula [PDF]
The Antarctic Peninsula (West Antarctica) marine ecosystem has undergone substantial changes due to climate-induced shifts in atmospheric and oceanic temperatures since the 1950s. Using 25 years of satellite data (1998-2022), this study presents evidence

Low meltwater input, cold temperatures, and high salinity accompanied a large diatom bloom off the Northern Antarctic Peninsula in 2015/2016 and suggests such blooms may be restricted under warmer conditions, according to direct measurements and remote ...

Abstract The northern Antarctic Peninsula is a key region of the Southern Ocean due to its complex ocean dynamics, distinct water mass sources, and the climate‐driven changes taking place in the region. Despite the importance of macronutrients in supporting strong biological carbon uptake and storage, little is known about their spatiotemporal ...

Ocean acidification affects pigment concentration and photoprotection of marine phytoplankton
Abstract Ocean acidification produces significant changes on phytoplankton physiology that can affect their growth and primary production. Among them, a downregulation of the enzymatic activity and the production of different cellular metabolites, including chlorophyll a (Chl a), has been observed in high CO2 cultures under stable conditions.

Modelling ecological communities when composition is manipulated experimentally
Abstract In an experimental setting, the composition of ecological communities can be manipulated directly. Starting from a pool of n species, it is possible to co‐culture species in different combinations, ranging from monocultures, to pairs, and all the way up to the full species pool.

Fisheries management influences phytoplankton biomass of Amazonian floodplain lakes
Tropical freshwaters fisheries typically assume that fish biomass is controlled by bottom‐up mechanisms, so that overexploitation of large predators would not affect overall ecosystem productivity. Our results, however, show that top‐down forces are important drivers of primary productivity in tropical lakes, above and beyond the effects of bottom‐up ...

As áreas de conservação desempenham um papel importante para conter a perda de habitat e a biodiversidade. No entanto, pouco se sabe sobre a influência dessas áreas nos ecossistemas aquáticos e, principalmente, na comunidade fitoplanctônica.
