Forecasting the responses of populations and ecosystems to climate change requires that we understand both the direct effects of temperature on organism physiology and the indirect effects of temperature change on interactions such as predation and competition. The sea star Pisas- ter ochraceus is a keystone predator in the rocky intertidal zone with a broad geographic distribution along the west coast of North America. We developed a mechanistic heat budget model that uses environmental data…

Recent Advances in Data Logging for Intertidal Ecology
Temperature is among the most ubiquitous determinants of organism growth, survival and reproduction. Accurate recordings and predictions of how the temperatures of plants and animals vary in time and
redicting intertidal organism temperatures with modified land surface models avid
Animals and plants in the marine intertidal zone live at the interface between terrestrial and marine environments. This zone is likely to be a sensitive indicator of the effects of climate change in
Manipulating thermal stress on rocky shores to predict patterns of recruitment of marine invertebrates under a changing climate
For rocky intertidal organisms, temperature is often considered the most influential factor governing early survival and growth. Nevertheless, our review of the literature revealed that few studies
Using biomimetic loggers to measure interspecific and microhabitat variation in body temperatures of rocky intertidal invertebrates
The results provide new evidence that unique thermal properties and microhabitat preferences may be important determinants of species’ capacity to cope with climate change.
When to worry about the weather: role of tidal cycle in determining patterns of risk in intertidal ecosystems
Species range boundaries are determined by a variety of factors of which climate is one of the most influential. As a result, climate change is expected to have a profound effect on organisms and
Behavioral thermoregulation in a tropical gastropod: links to climate change scenarios
A correlation between BT and substrate temperature (ST) was detected from field observations which suggests a possible causal relationship between both substrate and BTs and supports the crucial need to integrate intertidal invertebrate behavioral responses to thermal constraints in climate change studies.
Body temperatures of an intertidal barnacle and two whelk predators in relation to shore height, solar aspect, and microhabitat
This work developed biomimetic physical models of 3 common northeastern Pacific intertidal species: 2 predatory dogwhelks, Nucella ostrina and N. lamellosa and their barnacle prey, and established 42 biomimetics in up to 11 different microhabitats within an approximately 100 m2 region of the shoreline on San Juan Island, Washington, USA.


Testing the effects of wave exposure, site, and behavior on intertidal mussel body temperatures: applications and limits of temperature logger design
A temperature logger is designed that thermally matches (similar size, color, morphology and thermal inertia) living mussels of the species M. californianus, and its ability to provide realistic measurements of body temperature in the field is tested, which indicated no significant influence of gaping on body temperature.
Hot limpets: predicting body temperature in a conductance-mediated thermal system
A simple heat-budget model of the limpet Lottia gigantea is proposed, which predicts the daily maximal body temperatures of live limpets within a fraction of a degree, suggesting that it may be a useful tool for exploring the thermal biology of limpets and for predicting effects of climate change.
Factors affecting the feeding rate of the winkle Littorina littorea
The winkle Littorina littorea (L.) feeds mainly when moistened by the tide and is quiescent when exposed to the drying effects of the wind and sun. Upper shore winkles thus experience a reduced
