A non-native habitat-former mitigates native habitat loss for endemic reef fishes.

TLDR
It is indicated that the non-native canopy provides a viable habitat for endemic fish and may play a role in sustaining native fauna populations in this degraded ecosystem, and managers are recommended to consider the role of non- native habitats within the context of environmental change.

Individual Morphology and Habitat Structure Alter Social Interactions in a Range-Shifting Species

TLDR
This work examined how individual morphology and foundation species structure impact the ritualistic aggression behavior of the range shifting mangrove tree crab Aratus pisonii between its historic and colonized habitats.

High kelp density attracts fishes except for recruiting cryptobenthic species.

Habitat value of bivalve shellfish and seaweed aquaculture for fish and invertebrates: Pathways, synthesis and next steps

TLDR
The major mechanisms and pathways by which bivalve and seaweed aquaculture may positively influence the structure and function of faunal communities are described—including provision of structured habitat, provision of food resources and enhanced reproduction and recruitment—and the role of the species cultivated and cultivation gear in affecting habitat value is identified.

Effect of foresting barren ground with Macrocystis pyrifera (Linnaeus) C. Agardh on the occurrence of coastal fishes off northern Chile

Macrocystis pyrifera kelp beds play a significant ecological role along the coast of Chile. Besides their importance as food, protection structures, substrata, microhabitats and nurseries, regularly

Can ecosystem functioning be maintained despite climate‐driven shifts in species composition? Insights from novel marine forests

Climate change is driving a redistribution of species and the reconfiguration of ecological communities at a global scale. Persistent warming in many regions has caused species to extend their

Coastal ocean acidification and nitrogen loading facilitate invasions of the non-indigenous red macroalga, Dasysiphonia japonica

TLDR
It is suggested that eutrophic estuaries subject to peak annual temperatures may be particularly vulnerable to future invasions of D. japonica as ocean acidification intensifies and nutrient reductions would serve as a management approach that would make coastal regions more resilient to invasions by this macroalga.

Kelp (Saccharina latissima) Mitigates Coastal Ocean Acidification and Increases the Growth of North Atlantic Bivalves in Lab Experiments and on an Oyster Farm

TLDR
Results suggest that photosynthesis by S. latissima grown at densities associated with aquaculture increased pH and decreased pCO2, fostering a carbonate chemistry regime that maximized the growth of juvenile bivalves.

Habitat complexity mitigates trophic transfer on oyster reefs

TLDR
Structured habitats within several aquatic systems have been characterized as having higher abundances of both predators and their prey, and habitat complexity appears to enhance predator foraging efficiency by reducing interference competition among predators.

Faunal communities in seagrass beds: A review of the influence of plant structure and prey characteristics on predator-prey relationships

TLDR
It is suggested that the abundance of many species, both epifauna and infauna, is positively correlated with two distinct aspects of plant morphology: 1) the root-rhizome mat, and 2) the plant canopy.

Invasive seaweeds transform habitat structure and increase biodiversity of associated species

TLDR
A long-term shift in foundation species towards a dominance of invasive seaweeds that directly reduce canopy height and increase the 2D biogenic structure of the habitat is demonstrated.

Habitat structural complexity mediates the foraging success of multiple predator species

TLDR
Habitat structure can influence multiple predator effects, and support the mechanism of increased prey refuge in more structurally complex macrophytes, as demonstrated by the results of a fully crossed four-factorial laboratory experiment.

Ecosystem structure and services in eelgrass Zostera marina and rockweed Ascophyllum nodosum habitats

TLDR
It is demonstrated that marine vegetation provides important habitat, nitrogen, and carbon storage services, yet the extent of these services depends on the foundation species and its architecture, yet changes in canopy structure will have profound effects on associated food webs and ecosystem services.

Habitat structure and predator—prey interactions in vegetated aquatic systems

Many common features of aquatic habitats provide complexity in an otherwise unstructured water column. Abiotic elements include consolidated and unconsolidated sediments as well as many types of

Juvenile fish assemblages in temperate rocky reefs are shaped by the presence of macro-algae canopy and its three-dimensional structure

TLDR
Among Cystoseira forests, juvenile assemblages varied through space in terms of total abundance, composition, richness and taxa-specific patterns, and more than half of this variability was explained by forest descriptors, namely small variations in canopy structure and/or depth.

Engineering or food? mechanisms of facilitation by a habitat-forming invasive seaweed

TLDR
The results demonstrate that invasive ecosystem engineers can dramatically affect the distribution and abundance of native species by providing a novel protective structure.
