This paper presents the results of surveys quantifying species richness of rocky intertidal invertebrates across a potential biogeographic barrier on the south-eastern coast of Australia, as well as at Red Bluff, which is an isolated rock platform within the otherwise soft-sediment barrier. It was predicted that the number and composition of invertebrate species would differ on either side of the barrier and at Red Bluff and that these differences would be related to the potential for dispersal of the constituent species. Time-per-area searches at two sites within each of five rock platforms on either side of the barrier and at Red Bluff revealed that species richness and composition differed significantly on either side of the barrier, and that Red Bluff supported many species on both sides of the barrier, indicating its potential as a stepping-stone. The distribution of species was not related to their potential for dispersal, because potentially ‘good’ dispersers with planktonic larvae were sometimes restricted to one side of the barrier and potentially ‘poor’ dispersers with direct developing juveniles were present on both sides of the barrier. These results support increasing evidence that the geographic distribution of intertidal invertebrates cannot be inferred by simple reference to their life histories.

AbstractMeasurements of life-history traits can reflect an organism’s response to environment. In wave-dominated rocky intertidal ecosystems, obtaining in-situ measurements of key grazing invertebrates are constrained by extreme conditions. Recent research demonstrates mollusc shells to be high-resolution sea-surface temperature proxies, as well as archival growth records. However, no prior molluscan climate proxy or life-history reconstruction has been demonstrated for the tropical rocky intertidal environment—a zone influenced by warmer waters, mixed tides, trade-wind patterns, and wave-action. Here, we show near-daily, spatiotemporal oxygen isotope signatures from the tropical rocky intertidal environment by coupling secondary ion mass spectrometry analysis of oxygen isotopes with the sclerochronology of an endemic Hawaiian intertidal limpet Cellana sandwicensis, that is a significant biocultural resource harvested for consumption. We also develop a method for reliable interpretation of seasonal growth patterns and longevity in limpets. This study provides a robust approach to explore tropical intertidal climatology and molluscan life-history.

New Evidence

Until recently, marine scientists have relied heavily on satellite sea surface temperatures and terrestrial weather stations as indicators of the way in which the thermal environment, and hence the body temperatures of organisms, vary over spatial and temporal scales. We designed biomimetic temperature loggers for three species of rocky intertidal invertebrates to determine whether mimic body temperatures differ from the external environment and among species and microhabitats. For all three species, microhabitat temperatures were considerably higher than the body temperatures, with differences as great as 11.1°C on horizontal rocky substrata. Across microhabitats, daily maximal temperatures of the limpet Cellana tramoserica were on average 2.1 and 3.1°C higher than body temperatures of the whelk Dicathais orbita and the barnacle Tesseropora rosea respectively. Among-microhabitat variation in each species’ temperature was equally as variable as differences among species within microhabitats. Daily maximal body temperatures of barnacles placed on southerly facing vertical rock surfaces were on average 2.4°C cooler than those on horizontal rock. Likewise, daily maximal body temperatures of whelks were on average 3.1°C cooler within shallow rock pools than on horizontal rock. Our results provide new evidence that unique thermal properties and microhabitat preferences may be important determinants of species’ capacity to cope with climate change.
