Home Field Advantage: Sprint Sensitivity to Ecologically Relevant Substrates in Lizards
… study measures sprint sensitivity to substrate rugosity among six lizard species that occupy rocky, sandy, and/or semi-arboreal habitats. Lizards that use rocky habitats are less sensitive to changes in substrate rugosity, followed by arboreal lizards, and then by lizards that use sandy …

Investigation and development of techniques for the characterisation of the synthetic/biological interface
… is a protein-mediated event. A range of surface rugosity can be produced on polystyrene, and the results presented here show that surface rugosity does not play a major role in determining a material's cell adhesiveness. Contact angle measurements showed that surface energy (specifically the …

Distribution and community structure of Chaetodontidae (Perciformes) in iSimangaliso Wetland Park with the view to applying the Butterflyfish Indicator Hypothesis in this region of South Africa
… (sanctuary or partially protected), reef rugosity and site effects. 78 transects across 13 dive sites were swum using Underwater Video Census (UVC) for data capture. Reef rugosity displayed no impact on any of the sampled factors, whilst site and protection level did. Protection was the …

Surface adsorption and pore-level properties of mineral and related systems of relevance to the recycling of paper
… surface area could be attributed to nano rugosity. The nano rugosity was responsible for the enhanced wetting of a sample. A zero length column was used to study diffusion and desorption of benzene with calcium carbonate. Desorption and diffusion coefficients for calcium carbonate systems …

Ultrasound propagation in colloidal dispersions
… than expected. This is attributed to particle rugosity. Measurements of a[alpha] and c using non-gelling aqueous kaolinite suspensions are shown to agree well with theory when the eccentricity and the interactions of particles are taken into account. For gelling aqueous bentonite suspensions, …

Patterns of distribution, abundance and community composition of rock pool fishes in Goukamma Nature Reserve, South Africa
… temporal (Season), abiotic (Area, Height, Depth, Rugosity) and biological (Rock, Algae,) characteristics of rock pools on the distribution, abundance, diversity and community composition of rock pool fishes. A total of 747 fishes, representing seven families and 16 species were collected, using a …

The Influence of Forest Structure on Sumatran Orangutan Nesting and Densities in the Lowland Dipterocarp Forests of North Sumatra
… as higher canopy density, fewer gaps, increased rugosity and higher stem density. Nest densities were also associated with reduced distance to the edge of the forest, further research is needed to determine whether this is due to orangutans utilising neighbouring plantations. Our results show the …

Cellular interaction with novel biomaterials
… in cell adhesion may be due to the increased rugosity of the material. As the degradation continued the number of cells adhering to the samples decreased, this may indicate that the polarity was inhibitory to cell adhesion during the later stages of degradation.

Understanding the role of TapA in the formation of <i>B. subtilis</i> biofilms: a biochemical and genetic analysis
… of the TapA protein is sufficient to restore rugosity to a ΔtapA mutant biofilm. Genetic analysis of the minimal functional unit identified key amino acids needed for the function of TapA, highlighting the importance of a potential β-strand secondary structure in the Nterminus of TapA. …

Concrete ecological enhancement in the temperate marine environment
… the micro- and macro-scale superficial rugosity which is known to reliably increase colonisation. The impact of colonisation on concrete infrastructure is then reviewed, and it is suggested that bioprotective and biodeterioration of concrete substrates occur in tandem. Some species may …

Multi-trophic Biodiversity Increases with Increasing Structural Complexity of Forest Canopy
<p>Understanding the effects of forest canopy structural complexity on multi-trophic diversity is critical for conserving biodiversity and managing land sustainably. But multi-trophic diversity is often ignored when making decisions about land management due to lack of cost- and time-effective …

Material Virtuality: Remaking Rio de Janeiro’s Past and Present through Digital Media
Since the 1970s, Brazil’s authorities have regarded the country’s past as a source of cultural and economic value (Gonçalves 2007; Collins 2015). In the late 2000s, a boom in Brazil’s consumer economy served to make smartphones and social media ubiquitous across the country (Spyer 2017). This …
