Data from: A cross-scale trophic cascade from large predatory fish to algae in coastal ecosystems
Trophic cascades occur in many ecosystems, but the factors regulating them are still elusive. We suggest that an overlooked factor is that trophic interactions (TIs) are often scale-dependent and possibly interact across spatial scales. To explore the role of spatial scale for trophic cascades, and particularly the occurrence of cross-scale interactions (CSIs), we collected and analysed food-web data from 139 stations across 32 bays in the Baltic Sea. We found evidence of a four-level trophic cascade linking TIs across two spatial scales: at bay scale, piscivores (perch and pike) controlled mesopredators (three-spined stickleback), which in turn negatively affected epifaunal grazers. At station scale (within bays), grazers on average suppressed epiphytic algae, and indirectly benefitted habitat-forming vegetation. Moreover, the direction and strength of the grazer–algae relationship at station scale depended on the piscivore biomass at bay scale, indicating a cross-scale interaction effect, potentially caused by a shift in grazer assemblage composition. In summary, the trophic cascade from piscivores to algae appears to involve TIs that occur at, but also interact across, different spatial scales. Considering scale-dependence in general, and CSIs in particular, could therefore enhance our understanding of trophic cascades.
Figure 6 in Extension of fangs during the predatory jumps of jumping spiders (Araneae: Salticidae)
Figure 6. SEM images of the left chelicera of two Phidippus audax (Hentz 1845) from Iowa City, Iowa. 1, Posterior-distal view, penultimate, adapted after Hill (1977). 2, Posterior view, adult male. Note the presence of one large tooth on the posterior margin, and two successively smaller teeth on the anterior margin, of each fang groove. The opening of the venom duct is near the tip of each fang and, proximal to this duct, lies a sharp, microserrated interior edge.

Fig. 2 in Physical evidence of predatory behavior in Tyrannosaurus rex
Fig. 2. CT scans of the fused hadrosaur vertebrae, showing embedded theropod tooth and reactive bone (A–c). Longitudinal slice through the fused vertebrae shows the substantial overgrowth of reactive bone on the outside of the centra, while the articular surfaces remain largely unaffected (A). Two oblique slices through the vertebrae show the embedded theropod tooth in cross-section and the reactive bone that partially surrounds it (B and c). (Scale bars: A, 20 mm and B and c, 10 mm.)
