Rocky shore microbial diversity presents an excellent system to test for microbial habitat specificity or generality, enabling us to decipher how common macrobiota shape microbial community structure. At two coastal locations in the northeast Pacific Ocean, we show that microbial composition was significantly different between inert surfaces, the biogenic surfaces that included rocky shore anim...

The diversity of form among benthic marine plants and animals on rocky coasts is remarkable. Stiff and strong organisms grow alongside others that are compliant and flimsy. Given the severity of wave action on many shores and thus the potential for the imposition of large hydrodynamic forces, this immediately raises the question of how, from this overall spectrum of designs, flexible and weak o...

A new species of the red algal genus Gelidium, G. omanense M.J. Wynne, is described from the Sultanate of Oman, northern Arabian Sea. This species is a very commonly occurring eulittoral seaweed on the Omani coast, essentially one of the dominant species during the summertime southwest monsoon on exposed rocky shores. Its distribution is from Dhofar (southern Oman) in the west to Masirah Island...

Organisms face continual fluctuations in global climatic processes to which they must adapt or perish. Considering that many species are key habitat formers and energy producers, such responses to climate change can have significant population, community and even ecosystem consequences. Paleo-records of ecosystem responses to past environmental variability have proven invaluable for studying im...

This project follows a tradition of survey work undertaken to appraise physical and biological damage in the aftermath hurricane-strength winds waves at given locality where conditions were well documented prior arrival particular storm. The is 12 m limestone terrace Arroyo Blanco on eastern shores Isla del Carmen Baja California Sur, Mexico. A study February 2018 established that surface cover...

In the framework of stock enhancement, field experiments were conducted between March and July 2021 in rocky shores Central Portugal to test usefulness refuges calcein marking for juvenile sea urchins releases. Individuals with 10–20 mm diameter captured nature tagged through immersion a bath concentration 150 mg L −1 , during 48 hr. Artificial shelters used provide refuge an acclimatization st...

Numerous studies have demonstrated population genetic structuring in marine species, yet few have investigated the effect of vertical zonation on gene flow and population structure. Here we use three sympatric, closely related clinid species, Clinus cottoides, C. superciliosus and Muraenoclinus dor salis, to test whether zonation on South African intertidal rocky shores affects phylogeographic ...

Mussels form dense aggregations that dominate temperate rocky shores, and they are key aquaculture species worldwide. Coastal environments are dynamic across a broad range of spatial and temporal scales, and their changing abiotic conditions affect mussel populations in a variety of ways, including altering their investments in structures, physiological processes, growth, and reproduction. Here...
