Abstract: SUMMARYOn rocky shores, wave-swept macroalgae experience dramatic and repeated wave-induced hydrodynamic forces. However, previous studies of macroalgal mechanics have shown that individual waves are not forceful enough to account for observed rates of breakage. Instead, fatigue may contribute to algal breakage, with damage accumulating over time in conditions of repeated loading. Here I examine the entire process of fatigue, from crack initiation to eventual specimen fracture, in the common red alga Mazzaella… Show more

“…Fatigue behavior of M. flaccida has been quantified previously with standard laboratory measurement techniques (Mach, 2009). In the approach employed, each blade specimen was extended to a given tensile force and then relaxed to 0N, repeatedly, until the specimen broke.…”

“…Hansen and Doyle, 1976;Foster, 1982;Seymour et al, 1989;Dudgeon and Johnson,eventually cause specimen fracture. Mach (Mach, 2009) then documented that the entire process of fatigue failure, from the formation of small cracks through their growth to the point of specimen rupture, occurs predictably in the seaweed Mazzaella. It has thus been established that flat-bladed seaweeds fail by fatigue in standard laboratory loading conditions.…”

“…Because joints do not weaken appreciably through repeated loadings, whether a frond will survive or not is determined by the largest force it encounters. (This is in contrast to fleshy red algae, in which the accumulated damage from small forces limits size; Mach, 2009;Mach et al, 2007Mach et al, , 2011 Thus, from easily acquired records of maximum wave force (Denny and Wethey, 2001), one can accurately estimate the maximum size to which C. cheilosporioides' fronds can grow in a given wave environment (Martone and Denny, 2008a;Denny, 2016). Because C. cheilosporioides is a major competitor for space in the low intertidal zone, these estimates of maximum size can be valuable when considering the ecological consequences of a changing wave climate.…”
