Extinction, recolonization, and the genetic structure of tidepool copepod populations
Evolutionary Ecology, 1994Extinction and recolonization in metapopulations may either increase or decrease genetic differentiation among populations, but recent genetic models predict increased differentiation under most circumstances of recolonization. I examine this prediction empirically using tidepool populations of the marine tidepool copepodTigriopus californicus.

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

Persistent regional variation in populations of a tidepool fish
Journal of Experimental Marine Biology and Ecology, 2007Abstract Understanding the factors that drive population dynamics is particularly challenging in systems that are connected via propagule dispersal because the rate of arrival of new individuals is both notoriously unpredictable and potentially critical in determining future dynamics.

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.

Extinction, colonization, and species occupancy in tidepool fishes
Oecologia, 1998Despite the increasing sophistication of ecological models with respect to the size and spatial arrangement of habitat, there is relatively little empirical documentation of how species dynamics change as a function of habitat size and the fraction of habitat occupied.

Cross‐Tolerance in the Tidepool Sculpin: The Role of Heat Shock Proteins
Physiological and Biochemical Zoology, 2005Cross-tolerance, or the ability of one stressor to transiently increase tolerance to a second heterologous stressor, is thought to involve the induction of heat shock proteins (Hsp). We thus investigated the boundaries of cross-tolerance in tidepool sculpins (Oligocottus maculosus) and their relationship to Hsp70 levels. Survival of sculpins exposed to

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.

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.

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.

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 ...
