Kelp-forest dynamics controlled by substrate complexity

Proceedings of the National Academy of Sciences of the United States of America, 2022
Significance Kelp forests are declining worldwide due to varied combinations of environmental change and the trophic downgrading of urchin-controlling predators. These processes have increased the frequency and extent of rapid, nonlinear shifts to so-called urchin barrens whose ecological functioning and services are reduced relative ...

Impact of kelp forest on seawater chemistry – A review

Marine Pollution Bulletin, 2023
Kelp forests, globally distributed in cool temperate and polar waters, are renowned for their pivotal role in supporting species diversity and fostering macroalgae productivity. These high-canopy algal ecosystems dynamically influence their surroundings, particularly by altering the physicochemical properties of seawater.

Influence of Kelp Forest Biomass on Nearshore Currents

Journal of Geophysical Research: Oceans, 2022
AbstractAs part of a project focused on the coastal fisheries of Isla Natividad, an island on the Pacific coast of Baja California, Mexico, we conducted a 2‐1/2 year study of flows at two sites within the island's kelp forests. At one site (Punta Prieta), currents are tidal, whereas at the other site (Morro Prieto), currents are weaker and may be more ...

Influence of kelp forests on flow around headlands

Science of The Total Environment, 2022
Kelp forests affect coastal circulation but their influence on upwelling around headlands is poorly understood. Tidal-cycle surveys off two headlands with contrasting kelp coverage illustrated the influence of kelp forests on headland upwelling. Underway acoustic Doppler current and backscatter profiles were collected simultaneously to surface water ...

Scale-specific drivers of kelp forest communities

Oecologia, 2017
Identifying spatial scales of variation in natural communities and the processes driving them is critical for obtaining a predictive understanding of biodiversity. In this study, we focused on diverse communities inhabiting productive kelp forests on shallow subtidal rocky reefs in southern California, USA.

Endangered giant kelp forests support similar fish and macroinvertebrate communities to sympatric stipitate kelp forests

Biodiversity and Conservation
AbstractKelp forests provide habitat for many species, but it remains uncertain whether specific kelp forest types support distinct biodiversity. Surface canopy-forming giant kelp (Macrocystis pyrifera) forests in Tasmania, Australia, have declined significantly due to climate change, and have been widely replaced by forests dominated by smaller ...

Stability of Atlantic kelp forests

Trends in Ecology & Evolution, 1988
plants. The Nova Scotian kelp forest thinned out over the winter as kelp blades eroded and, presumably, as plants were dislodged during winter storms. Rapid kelp growth and recruitment resulted in the closure of the canopy shortly after. Surprisingly, there was no effect of understory seaweeds on the recruitment of L.

KELP ECOLOGY AND THE POINT LOMA KELP FOREST: A BLEND OF THE OLD AND THE NEW

Journal of Phycology, 2000
The history of the Point Loma kelp forest parallels that of the earlier pioneers in Europe, with an early descriptive focus moving quickly toward mechanistic studies. At Point Loma, research was initiated because of large‐scale loss of kelps, so from the beginning there was an urgency to restore the kelp forest with a concomitant focus on sea urchin ...

State of the world’s kelp forests

One Earth
Kelp forests, vital to global biodiversity and coastal economies, face degradation and underfunded conservation. The "State of the World's Kelp Forests"finds that 16% of the kelp biome is protected and 2% of the restoration target is met and provides a rallying call to meet global commitments for kelp forest conservation.
