“…Similar trends were found for the bioturbation activity by a heart urchin (Hollertz and Ducheˆne, 2001) or the reworking rate by a surface deposit-feeding bivalve (Maire et al, 2007). In another study, Berkenbusch and Rowden (1999) have followed the rate of sediment expulsion by the burrowing shrimp Callianassa filholi at an intertidal sandflat in New Zealand over a 12-month period. They found that sediment expulsion was significantly related to seawater temperature, being maximal in summer and dropping to a minimum at the end of winter.…”

“…Such thermal thresholds in sediment reworking have been reported in White et al (1987) for oligochaetes experiencing cycles of fall and rise temperatures between 4 and 20 xC, and in Berkenbusch and Rowden (1999) who followed the rate of sediment expulsion by a burrowing shrimp over a 12-month period. Nevertheless, most other previous studies that have focused on the relationship between temperature and sediment reworking have been limited to two or three temperature treatments (Ouellette et al, 2004;Maire et al, 2007), probably for practical and technical constraints.…”

-Water temperature is a key parameter that regulates activities of ectotherms (e.g., fish) and has been projected to rise in the future in the context of climate change. Surface sediment disturbance (SSD) is an important function performed by fish that modifies benthic habitat properties and may thus influence ecosystem functioning. However, the link between SSD by fish and temperature remains unexplored. In this study, we experimentally assessed the influence of two contrasted temperatures (10 versus 20 xC) on SSD by three freshwater fish species in aquaria. After 10 days, the total surface disturbed by the species was approximately 2-3 times higher at warm than at cold temperature but the number and area of patches disturbed by the species were not significantly different. The stone loach Barbatula barbatula, a benthic fish species, had a higher SSD activity (i.e., total surface disturbed, number and size of patches disturbed) both at cold and warm temperatures than two cyprinid species, chub Squalius cephalus and sofie Parachondrostoma toxostoma. On average, SSD by B. barbatula resulted in approximately two and three more patches than the cyprinid species at 10 and 20 xC, respectively, and the mean patch area disturbed by B. barbatula was about two times larger than the ones disturbed by the cyprinid species. The total surface disturbed by the cyprinids at warm temperature was roughly equivalent to the surface disturbed by B. barbatula at cold temperature. Our results thus suggest that SSD by fish could increase in future warmed conditions.

The impact of bioturbation by the burrowing ghost shrimp Callianassa filholi on benthic community composition was examined in relation to seasonal and small-scale spatial changes. Sites of naturally occurring low and high densities of C. filholi on an intertidal sandflat represented hfferences in bioturbation activity throughout the year. Univariate and multivariate analyses showed significant differences in community composition between high-and low-density sites. The total number of species and total number of individuals were lower at high-density sites. A corophiid amphipod, Paracorophium escavatum and a small bivalve, Perrierina turneri, appeared to have the greatest discriminating significance wlth lower abundances of both species at sites of high C. filholi density. Even though differences between sites of different dens~ty pers~sted throughout the year, the impact of bioturbation depended on season. Bioturbation had the highest maximum correlation to changes in macrofauna1 community composition in winter, spring and, in association with seagrass blomass (Zostera novazelandica), in autumn. During summer, however, seagrass biomass contnbuted the most to observed differences and appeared to compensate for generally high bioturbation activity. The results imply that bioturbation impacted on macrofauna community composition over a small spatial scale and, although its impact varied seasonally, imposed patterns persisted throughout the year. As such, C. filholi can be considered a keystone species.

“…As low values for all three size parameters coincided with both low seawater temperature and relatively high organic content of the sediment, it is probable that either, or the combination of both environmental factors influence the burrow morphology. As there was no statistically significant difference in mean organic content between seasons (F-test,F= 5A;P> 0.05), but a strong link between the shrimp's sediment turnover activity and temperature (Berkenbusch & Rowden 1999), it is likely that the observed intraspecific variation in burrow morphology is related to seasonal changes in seawater temperature. However, this interpretation is confounded by the relationship between burrow size and organic content, and to provide unambiguous results, it is obviously necessary in the future to investigate the influence of both factors on burrow morphology independently.…”

“…It has been reported for temperate callianassid species that sediment turnover activity varies with season (Posey 1985;Swinbanks & Luternauer 1987). In particular, C. subterranea has been recorded to be virtually inactive at low temperatures (<7°C, Rowden et al 1998), and low sediment expulsion activity of C. filholi is significantly related to minimum seawater temperature in colder months (~7°C, Berkenbusch & Rowden 1999). As sediment reworking by deposit-feeding callianassids is intrinsically linked to burrow maintenance and feeding (Stamhuis et al 1997), it is likely that low sediment turnover rates are reflected in smaller-sized burrows during colder months.…”

Burrow morphology and intraspecific burrow plasticity in relation to environmental conditions were examined for an intertidal population of Callianassa filholi Milne-Edwards, 1878 in southeastern New Zealand. Multivariate analysis of burrow features revealed no significant differences in burrow morphology between seasons. However, dissimilarities between burrows from different seasons could be identified and included differences in lateral extent, total length, and volume of burrows. These size parameters each showed low values in winter, coinciding with low seawater temperature and high organic content of the sediment. There was no significant relationship between any of the three size parameters and sediment grain size or shore height of the burrow, but lateral extent and total length of the burrow were significantly related to organic content of the sediment, decreasing with increasing organic content. Furthermore, there was a significant positive relationship between seawater temperature and total length of the burrow. Data from the present study imply that intraspecific variation in burrow morphology for callianassids is dependent on environmental variables, which has consequences for the construction of useful burrow models.
