Structure and resilience of a tidepool fish assemblage at Barbados
Environmental Biology of Fishes, 1994Fish collections from 19 tidepools on a rock plateau at Martins Bay, on the east coast of Barbados, taken on three occasions (1981,1983 and 1987) contained 2078 individuals of 63 species. The number of species, individuals and total biomass increased with pool size.

Diatom Communities of Tidepools: The Effect of Intertidal Height
Botanica Marina, 1992The diatom community that inhabits both the water-column and the benthos of tidepools positioned along an intertidal gradient, during late spring and early summer is described. Samples from the water-column and benthos of five tidepools, ranging from 1.5 to 6.5 m, were collected on five dates, and the diatom community benthos of five tidepools, ranging

Sodium regulation in the tidepool copepod Tigriopus californicus
Comparative Biochemistry and Physiology Part A: Physiology, 1981Abstract 1. 1. Body fluid water and sodium regulation in the marine copepod Tigriopus californicus were studied over a range of external sodium concentrations extending from 0.26 to 1.45 M. 2. 2. Body water content was constant at 87.5% of body weight. 3. 3.

Salinity tolerance of the tidepool shrimp palaemon ritteri holmes
Comparative Biochemistry and Physiology Part A: Physiology, 1975Abstract 1. The lower incipient lethal salinity for non-moulting Palaemon ritteri is 10% at 20°C. 2. The upper incipient lethal salinity for non-moulting P. ritteri is 47·5% at 20°C. 3. Recently moulted P. ritteri are unable to tolerate salinities of 15, 20 or 40%. 4.

Canadian Journal of Zoology, 2018
Rapidly changing environments pose unique challenges to the resident organisms. Tidepools in coastal environments vary in biophysical characteristics spatially and temporally, and how they vary determines their short- and long-term suitability as habitats and therefore influence on the distributions of tidepool organisms.

Tidepool power makes a surprising comeback [News]
IEEE Spectrum, 2013Fifty years ago this July, Electricite de France began sealing off Normandy's La Rance estuary from the sea. After three years of work, the world's first large-scale tidal power plant was born. The station operates still, generating up to 240 megawatts of renewable power as the twice-daily tides force water in and out of the estuary through the ...

Biomass compensation: Behind the diversity gradients of tidepool fishes
Population Ecology, 2019AbstractSpecies richness is unevenly distributed on the Earth, with biodiversity gradients of various spatial scales supposedly being affected by abiotic as well as biotic factors including community traits such as body size spectra and relative abundance patterns.

Fish diversity in tidepools: assembling effects of environmental heterogeneity
Environmental Biology of Fishes, 2017Tidepools are considered ecosystems of high interchangeable fish biota. However, natural and anthropogenic actions that alter negatively marine ecosystems functioning (e.g., algal exploitation) are causing homogenization of fish biodiversity. Here, we describe the functional and taxonomic assembling of fishes in beach rocks of northeastern Brazil ...

Short-term changes in tidepools following two hurricanes
Hydrobiologia, 1996Three tidepools in the rocky intertidal zone of coastal Maine, USA, were examined before and after the passing of two hurricanes: Gloria, in 1985, and Bob, in 1991. Surface area was little changed in one pool, and reduced in a second pool that were formed from rock.
