Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Summary Changes to organismal growth induced by environmental stress are orchestrated at the cellular level. These periods of stress may be followed by recovery periods, when plants have the opportunity to return to normal growth conditions. However, the cell cycle mechanisms underlying recovery are poorly understood.

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Two decades of changes in the global network of illegal wildlife trade
Abstract Understanding how illegal wildlife trade (IWT) has changed over time is fundamental for biodiversity conservation; however, knowledge of the network remains limited. We used TRAFFIC's IWT dataset, legal trade data from the CITES legal wildlife trade database as a benchmark, and network analysis to identify changes in IWT from 2000 to 2022. The

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...

Plant conservation in a changing Mediterranean world
The Mediterranean is one of five climatic regions on the planet characterised by a prolonged summer drought, exceptional plant diversity and high rates of endemism. We provide a framework to link the ecology of plant species conservation in the context of rapid and extreme climate deregulation to a philosophical typology of temporal attitudes (i.e ...
