“…diurnal, tidal or seasonal) that is not accounted for in survey designs, abundance and biomass estimates may be biased. Temperate reef-associated fishes typically have ranges with small 'core areas' (tens of metres in diameter; [44]) but may undertake brief longer range excursions (hundreds of metres to kilometres) to forage [22,44]. The 'snapshot' temporal scale of our surveys means that such foraging excursions are unlikely to be captured and hence observed communities may be 'subsidized' by prey production that occurs at a broader spatial scale than is represented by the distribution of fishes on transects.…”

The paradox of inverted biomass pyramids in kelp forest fish communities

et al. 2016

Theory predicts that bottom-heavy biomass pyramids or 'stacks' should predominate in real-world communities if trophic-level increases with body size (mean predator-to-prey mass ratio (PPMR) more than 1). However, recent research suggests that inverted biomass pyramids (IBPs) characterize relatively pristine reef fish communities. Here, we estimated the slope of a kelp forest fish community biomass spectrum from underwater visual surveys. The observed biomass spectrum slope is strongly positive, reflecting an IBP. This is incongruous with theory because this steep positive slope would only be expected if trophic position decreased with increasing body size (consumer-to-resource mass ratio, less than 1). We then used d 15 N signatures of fish muscle tissue to quantify the relationship between trophic position and body size and instead detected strong evidence for the opposite, with PPMR % 1650 (50% credible interval 280-12 000). The natural history of kelp forest reef fishes suggests that this paradox could arise from energetic subsidies in the form of movement of mobile consumers across habitats, and from seasonally pulsed production inputs at small body sizes. There were four to five times more biomass at large body sizes (1-2 kg) than would be expected in a closed steady-state community providing a measure of the magnitude of subsidies.

Many common fishes associated with Caribbean coral reef ecosystems use resources from more than 1 patch type during routine daily foraging activities. Few studies have provided direct evidence of connectivity across seascapes, and the importance of benthic seascape structure on movement behavior is poorly known. To address this knowledge gap, we coupled hydro-acoustic technology to track fish with seafloor mapping and pattern analysis techniques from landscape ecology to quantify seascape structure. Bluestriped grunts Haemulon sciurus and schoolmaster snapper Lutjanus apodus were tracked over 24 h periods using boat-based acoustic telemetry. Movement pathways, and day and night activity spaces were mapped using geographical information system (GIS) tools, and seafloor structure within activity spaces was mapped from high-resolution aerial photography and quantified using spatial pattern metrics. For both fish species, night activity spaces were significantly larger than day activity spaces. Fish exhibited a daytime preference for seascapes with aggregate coral reef and colonized bedrock, then shifted to night activity spaces with lowercomplexity soft sediment including sand, seagrass, and scattered coral/rock. Movement path complexity was negatively correlated with seascape complexity. This demonstrates direct connectivity across multiple patch types and represents the first study to apply quantitative landscape ecology techniques to examine the movement ecology of marine fish. The spatially explicit approach facilitates understanding to the linkages between biological processes and the heterogeneity of the landscape. Such studies are essential for identifying ecologically relevant spatial scales, delineating essential fish habitat and designing marine protected areas.

“…Most research on the home range of fishes has focused on freshwater taxa (Lyons & Lucas 2002), reefassociated fishes (Holland et al 1996, Zeller 1997, Eristhee & Oxenford 2001, seagrass or kelp bedassociated fishes (Topping et al 2005, Jadot et al 2006, and demersal fishes (Lembo et al 2002, Jorgensen et al 2006, Schroepfer & Szedlmayer 2006, Tolimieri et al 2009). Measurement of home ranges for pelagic fishes does not appear to have been examined.…”

Quantification of the movements and home ranges of highly mobile marine species is a challenging prerequisite for a more complete understanding of their ecology. Caranx crysos is a pelagic carangid found in large schools over the mid-shelf of the northern Gulf of Mexico. Twentythree C. crysos were surgically implanted with acoustic transmitters, and their positions were localized around a petroleum platform complex in the Gulf of Mexico using a hydrophone network. Fish were tracked during August 2005 for 23 d, and home ranges were calculated for individual fish over the daily, diel, and entire study period. Most fish showed a preference for a discrete area within the platform complex: 11 fish had a range centroid near one platform for at least 7 d, and 9 fish had a range centroid near one platform for at least 3 d. Only 3 fish showed no preference for a particular site within the platform complex. Mean core daily range varied from 373 to 2202 m 2 , while the 95% daily range was between 3082 and 14 333 m 2 . Evidence for diel differences in habitat use was also apparent. Hydrophones detected more transmissions during the day than during the night; however, only 3 fish had significantly larger home ranges during the day than during the night. There was a significant correlation between fish length and both the size of their overall core home range and the size of the 95% daily home range. Our results suggest that this schooling pelagic species establishes a home range in the vicinity of structure.
