Fig. 9 in Characterizing Late Pleistocene and Holocene Stone Artefact Assemblages from Puritjarra Rock Shelter: A Long Sequence from the Australian Desert

Fig. 9. Flake size and shape by analytical unit. Data are length/ breadth measurements for a representative sample of 769 complete flakes. (A) Comparison of units 1a–b (solid grey circles), and unit 2a (open squares). Late Holocene flakes are smaller and less variable in size than early Holocene/terminal Pleistocene flakes, but have similar proportions. (B) Comparison of units 2b–d (solid grey circles) and unit 2a (open squares). Late Pleistocene flakes are smaller than those in the early Holocene/terminal Pleistocene, but have similar variability and proportions.

Fig. 7 in Characterizing Late Pleistocene and Holocene Stone Artefact Assemblages from Puritjarra Rock Shelter: A Long Sequence from the Australian Desert

Fig. 7. Large flakes from late Pleistocene levels of Puritjarra rock shelter. All are from unit 2a except M11/26-1 (unit 2b). M10/16-2 is an ironstone flake struck from a horsehoof core, and has fine overhang-removal flaking along the platform edge. M10/20-3 is chert flake with evidence of a prior platform, showing that the core was rotated before this flake was detached.

Fig. 6. Small flakes from late Pleistocene levels of Puritjarra rock shelter. From unit 2c: N10/11-1. From unit 2b: N12/21-8, N12/21-15, N12/23-1, N18/13-1, M11/25-2. Remainder are from unit 2a. N12/21-8 and N12/17-4 each have a series of fine flakes scars along the platform edge, showing trimming of an overhang prior to detachment of the flake. N12/19- 5 exhibits a facetted platform. N11/22-5 is a sandstone flake struck from a bifacial core.

From unit 1c: M10/12-19. Unassigned 1b–c: ST5/3-4, ST5/4-4. M10/12-19 and M11/8- 6 are sandstone redirecting flakes. N5/6-2 is a single platform core split during knapping. QR9/1-3 is a small horsehoof core, with a base (shown) reduced as a bifacial core. The large platform core from Murantji (3) is on a flake of yellow-grey chert.

Fig. 10. Multivariate analysis of flake attributes, using the Canonical variates program in the MVARCH package. Data are for flakes where the full set of platform and flake attributes can be measured (N = 635). Scatter-plot shows the centroids for groups of flakes from each unit plots these against flake variables—raw material grain-size, flake weight, percentage cortex, length, breadth, thickness, platform breadth, platform thickness, platform angle, platform preparation, overhang removal, evidence of core rotation, and the number of flake scars on the dorsal surface.

Fig. 5. Graph showing increasing use of chert and chalcedony over time. Data are number of chert and chalcedony artefacts per spit (excavation unit), expressed as percentage of total number of artefacts in each spit. The plot shows data for the Main Trench only (excluding the following: spits without lithics; spits in 2d with only doubtful artefacts, features intrusive from higher levels).

Fig. 11 in Characterizing Late Pleistocene and Holocene Stone Artefact Assemblages from Puritjarra Rock Shelter: A Long Sequence from the Australian Desert

Fig. 11. Cores from terminal Pleistocene levels of Puritjarra rock shelter. All are from unit 2a. N5/22-1 is a bifacial core on sandstone. Remainder of artefacts are single platform cores. N9/9-2 is a small finely-made silcrete core with a flaked platform and fine overhang removal scars. N9/9-3 is a horsehoof core made on a cobble of exotic silcrete.

Fig. 4. Schematic diagram showing stratigraphic correlations between trenches. Layers I in Characterizing Late Pleistocene and Holocene Stone Artefact Assemblages from Puritjarra Rock Shelter: A Long Sequence from the Australian Desert

Fig. 4. Schematic diagram showing stratigraphic correlations between trenches. Layers I–III are labelled in bold. Identifiable cultural horizons (units 1a, 2a and 2c) are shown (stippled), as well as dated hearths (plano-convex features), 14C determinations (hatched rectangles), luminescence dates (open rectangles) and the maximum depth of late Holocene artefacts in each trench (T tula adzes; B backed artefacts/geometric microliths). Grid lines show depth (cm) below site datum. Horizontal stippled lines at 120 cm depth in N5/ N6 and in the Main Trench show the position of a silty band identified in grain-size analyses.

Characterizing juvenile dispersal dynamics of invasive barred owls: implications for management

Characterizing natal dispersal can help manage the spread of invasive species expanding their ranges in response to land use and climate change. The Barred Owl (Strix varia) is a prominent example of an apex predator undergoing a rapid range expansion, having spread from eastern to western North America where it is now hyperabundant—threatening the Northern Spotted Owl (S. occidentalis caurina) with extinction and potentially endangering many other native species. We attached satellite tags to 31 Barred Owl juveniles at the southern leading edge of the Barred Owl's expanding range in California to characterize natal dispersal patterns and inform management. Juveniles traveled up to 100km from natal territories and experienced high mortality (annual survival = 0.204). At landscape scales, juveniles preferentially used forests, shrublands, and lower elevations during dispersal and avoided grasslands and burned areas. At finer scales, juveniles preferred shorter (younger) forests, lower elevations, and drainages, and avoided unforested areas. Our results suggest the Barred Owl range expansion is being driven primarily by high reproductive rates and densities despite low juvenile survival rates and dispersal through putatively suboptimal younger forests as a result of exclusion from high-quality habitat by territorial individuals. These findings also point to several strategies for conserving Spotted Owls and other native species in the Barred Owl's expanded range, including: (1) creating and maintaining Barred Owl-free reserves bounded by open or high-elevation areas; (2) creating reserves large enough to reduce immigration by long distance dispersers; and (3) removing Barred Owls from large riparian corridors.

Characterization and effect of biomimetic surfaces based on the topography of a self-cleaning leaf on bacterial binding

Four self-cleaning leaves (Tenderheart, Cauliflower, White cabbage, and Leek) and the corresponding biomimetic surfaces were analyzed for their properties (water contact angle, surface hydrophobicity and roughness). The antifouling behavior was assessed by bacterial attachment, adhesion, and retention assays.
