Graba-Landry PhD thesis: The effect of increasing temperature to algae-fish interactions on coral reefs

This thesis investigated the role of temperature in influencing algae-fish interactions on coral reefs. Specifically the aims of the thesis were to determine: (1) the relative influence of natural variations in water temperature on the feeding rates of herbivorous fishes; (2) how rates of turf algae growth and feeding rates of herbivorous fishes change with seasonal variation in temperature; (3) how predicted increases in temperature are likely to affect the growth and survival of common coral reef macroalgae; (4) how individual metabolism, feeding rates, growth and body condition of a common herbivorous fish changes with temperature.  These aims were addressed in the following five chapters.

Chapter 2 investigates the influence of natural variation in temperature versus resource availability in influencing herbivore feeding rates by quantifying feeding of three functionally distinct herbivores among three latitudes and two seasons on the Great Barrier Reef (GBR), and among reefs with distinct algal communities.

Chapter 3 builds on the findings of Chapter 2, and investigates how seasonal variation in temperature influences the relative rates of herbivore feeding and turf algal growth in the northern GBR.

Chapter 4 uses experimental manipulation of temperature to investigate the influence of increasing temperature on the growth, survival, tissue quality and susceptibility to herbivory of adult and juvenile life stages of the common coral reef macroalgae Sargassum.

Chapter 5 uses juvenile Siganus doliatus, a common herbivorous reef fish, to investigate the effect of rearing temperature on physiological processes (i.e., oxygen uptake, feeding rate, growth and body condition).
