Marine invasive macroalgae can have severe local-scale impacts on ecological
communities. The kelp Undaria pinnatifida is one of the most successful marine invasive …

Human population density within 100 km of the sea is approximately three times higher than
the global average. People in this zone are concentrated in coastal cities that are hubs for …

New Zealand's coastal environment and associated habitats support valuable invertebrate
and finfish fisheries. Most of these fisheries are now fully exploited. Many have a history of …

Rising ocean temperature is a major driver of kelp forest decline worldwide and one that
threatens to intensify over the coming decades. What is not particularly well understood are …

Ecological theory predicts that demographic connectivity structures the dynamics of local
populations within metapopulation systems, but empirical support has been constrained by …

Increasing turbidity in coastal waters reduces benthic irradiance levels and consequently
poses a fundamental threat to benthic primary producers and the food webs they support. It …

Kelp forests around the world are under increasing pressure from anthropogenic stressors.
A widespread consequence is that in many places, complex and highly productive kelp …

Kelp forests form important habitat in temperate subtidal regions but are threatened by a
range of stressors that impact their abundance. In this study, we determined the effect of …

Kelp habitats contribute to marine productivity and diversity, making understanding the
constraints on their distribution important. In the Gulf of St. Lawrence, Alaria esculenta …

Replacement of kelp and fucoid forests by low biomass turfing communities or urchin
barrens has been identified in temperate marine ecosystems worldwide. Variation in the …
