ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

This study reports the accumulation of paralytic shellfish toxins (PSTs) in Atlantic horse mackerel (Trachurus trachurus) over a bloom of the toxigenic dinoflagellate Gymnodinium catenatum. High levels of toxins, up to 4800 μg STXeq kg–1, were registered

Emergence of a Resource Acquisition Trade‐off at the Community Scale during Environmental Change
A four‐decadal cycle of eutrophication and subsequent re‐oligotrophication in Lake Constance led to the emergence of a strong trade‐off between phosphate and light affinity. We derive an explanation for the emergence of this trade‐off from resource ratio theory and discuss the relevance of this novel concept for trait‐based ecology.

Nitrogen nutrition of harmful algal blooms in upwelling systems [PDF]
Blooms of toxic, or otherwise harmful phytoplankton species are known to occur in eastern boundary upwelling systems, coincident with the relaxation of upwelling in latesummer/autumn.

The alpha diversity and beta diversity of the harmful microalgae community exhibited significant variations in salinity and seasonality (p < 0.05). A wider range of environmental thresholds in high‐salinity samples than those in other samples of the harmful microalgae community.

Abstract Marine plankton capable of photosynthesis and predation (“mixoplankton”) comprise up to 50% of protist plankton and include many harmful species. However, marine environmental management policies, including the European Union Marine Strategy Framework Directive (MSFD) and the USEPA, assume a strict dichotomy between autotrophic phytoplankton ...

Occurrence and toxic profiles of paralytic shellfish toxins (PST) in the chocolata clam Megapitaria squalida were investigated. From December 2001 to December 2002, 25 clams were obtained monthly from Bahía de La Paz, Gulf of California.
