title: Bioenergetic modeling reveals opposing effects of ocean and terrestrial warming of an intertidal crustacean

description: Organism-level bioenergetics models (OBMs) are an emerging tool to predict
 organism-level consequences to dynamic temperature in field environments.
 Here we use an OBM to assess sensitivity to ocean and atmospheric warming
 for an intertidal barnacle, Balanus glandulus. We measure environmental
 conditions (aerial and aquatic temperature) at three intertidal heights
 over two 6-month intervals and compare observed growth to growth estimates
 based on a Numerical Scope for Growth model. This OBM integrates the
 effects of multiple thermal responses (e.g. feeding, respiration) in
 multiple contexts (aerial, aquatic). 
description: Length and growth measurements are determined from photoquadrat
 pixel data. Seperate experiments were used to characterize <em>B.
 glandula</em> response to temperature. This includes aquatic
 feeding, aquatic respiration, aerial exposure and recovery respiration. We
 also include an independent growth dataset (subtidal) used to parameterize
 the model.
