The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Algal Blooms What are they?

open access: yes, 2014
When phytoplankton – microscopic aquatic plants – occur in very large quantities, an algal bloom is said to arise. The water becomes cloudy and changes colour, and the algae form a layer on the surface, varying in thickness depending on the intensity of the bloom. This algal mass may be toxic, so you should avoid bathing in the water until the bloom is

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1904-1921, August 2026.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Managing for resilience with ecological structure: Portfolio effects in the Laurentian Great Lakes

open access: yesFrontiers in Ecology and the Environment, Volume 24, Issue 6, August 2026.
Combined effects of global change, including land conversion, biological invasions, and overexploitation, have degraded the resilience of ecosystems and the services they provide. Here, we identify key ecological structures and processes that can be targeted by management to improve resilience at scales ranging from single species to entire landscapes.

Salinity, turbidity, and chlorophyll drive zooplankton succession in a temperate estuary under anthropogenic pressure

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Estuarine zooplankton are vital primary consumers and essential for estuarine ecosystem functioning and productivity, but they face strong physico‐biochemical gradients and often anthropogenically altered habitats that impact their succession.
