Compound‐specific isotope analysis of benthic foraminifer amino acids suggests microhabitat variability in rocky‐shore environments

Ecology and Evolution, 2018
The abundance and biomass of benthic foraminifera are high in intertidal rocky‐shore habitats. However, the availability of food to support their high biomass has been poorly studied in these habitats compared to those at seafloor covered by sediments ...

Spatial inference of ancestor locations suggests northern refugia for canopy‐forming kelps in the Pacific Northwest

New Phytologist, EarlyView.
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...

Differential gene expression in Pyropia columbina (Bangiales, Rhodophyta) under natural hydration and desiccation conditions

Latin American Journal of Aquatic Research, 2013
In rocky shores, desiccation is triggered by daily tide changes, and experimental evidence suggests that local distribution of algal species across the intertidal rocky zone is related to their capacity to tolerate desiccation.

Morpho‐anatomical and genetic variation of Lithophyllum neo‐okamurae and L. okamurae (Corallinales, Corallinophycidae, Rhodophyta) from Jeju Island, Korea

Phycological Research, EarlyView.
SUMMARY Lithophyllum Philippi (Corallinales, Corallinophycidae, Rhodophyta) is a diverse genus of non‐geniculate coralline algae. Lithophyllum neo‐okamurae and L. okamurae are commonly found in the intertidal and subtidal zones of Jeju Island, Korea, where they contribute to local benthic communities.

Seasonal growth and reproductive dynamics of Chondrus ocellatus in relation to shore height in the Korean intertidal zone

Phycological Research, EarlyView.
SUMMARY We examined the seasonal growth and reproduction of the carrageenophyte Chondrus ocellatus in Hakampo, Korea (July 2014–April 2015), to understand its adaptation to environmental variability across the intertidal zone. Three hypotheses were tested: (1) growth is greater at the lower shore with reduced stress; (2) gametophytes dominate at the ...

Feasibility of restoring native oyster reefs in highly modified urban estuaries

Restoration Ecology, EarlyView.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Immediate Impact of the 2021 Harmful Algal Bloom in Southeast Hokkaido on the Rocky Intertidal Benthic Community and Its Spatial Variation

Journal of Marine Science and Engineering
There has been a limited number of studies on the effects of harmful algal blooms (HABs) on natural rocky intertidal ecosystems. From mid-September to early November 2021, an unprecedented HAB caused by Karenia selliformis hit the Pacific coast of ...

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

New records of hermit crabs, Calcinus morgani Rahayu and Forest, 1999 and Diogenes klaasi Rahayu and Forest, 1995 (Crustacea: Anomura: Diogenidae) from India

Journal of Threatened Taxa, 2011
Two species of hermit crabs, Calcinus morgani Rahayu and Forest and Diogenes klaasi Rahayu and Forest of the family Diogenidae, are recorded for the first time from the Indian coast.
