A molecular assessment of homing in the tidepool sculpin
Journal of Fish Biology, 2003Molecular analyses of the mitochondrial genome using restriction fragment length polymorphism (RFLP) were utilized to determine the existence of discrete populations of the tidepool sculpin Oligocottus maculosus from the Barkley Sound region of south‐western Vancouver Island, British Columbia.

Top-down and bottom-up factors in tidepool communities [PDF]
Journal of Experimental Marine Biology and Ecology, 2004 Recent studies suggest that nutrient variation influences rocky intertidal community structure, however empirical evidence is rare. In the Gulf of Maine, tidepools that occur on seagull feeding roosts are potentially subjected to regular nutrient loading

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.

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.

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.

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

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.
