Selection of perching site background color by Hamadryas feronia (Lepidoptera: Nymphalidae) in Costa Rica: Implications for industrial melanism

Revista de Biología Tropical, 2012
Observations of the increased frequency of melanic forms in moths of the genus Biston in Great Britain after the industrial revolution lead to the development of the theory of industrial Melanism. Nonetheless, arguments against that interpretation of the

Motion dazzle and camouflage as distinct anti-predator defenses

BMC Biology, 2011
Background Camouflage patterns that hinder detection and/or recognition by antagonists are widely studied in both human and animal contexts. Patterns of contrasting stripes that purportedly degrade an observer's ability to judge the speed and direction ...

Disruptive viability selection on a black plumage trait associated with dominance. [PDF]

, 2015
Traits used in communication, such as colour signals, are expected to have positive consequences for reproductive success, but their associations with survival are little understood.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Environmentally induced changes in carotenoid-based coloration of female lizards: a comment on Vercken et al. [PDF]

, 2008
Colouration may either reflect a discrete polymorphism potentially related to life-history strategies, a continuous signal related to individual quality or a combination of both. Recently, Vercken et al. [J. Evol. Biol.

Adding Color to Conflict: Disruptive Students’ Drawings of Themselves with Their Teachers

The Elementary School Journal, 2017
AbstractBuilding on work examining teachers’ perceptions of the student-teacher relationship, this study investigated how young students draw themselves with their teachers. Fourteen kindergarten and first-grade teachers each nominated 2 disruptive and 2 well-behaved students. Students then completed 1 drawing of themselves with their classroom teacher

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Area integrity index with random rearrangement (AIIRR): A new concept for quantifying disruptive colorations

Methods in Ecology and Evolution
Disruptive coloration is one of the camouflaging strategies that use conspicuous coloration patterns to destroy the visual integrity of an object and interfere with the observer's visual perception.

Effects of CO2-induced pH reduction on the exoskeleton structure and biophotonic properties of the shrimp Lysmata californica. [PDF]

, 2015
The anticipated effects of CO2-induced ocean acidification on marine calcifiers are generally negative, and include dissolution of calcified elements and reduced calcification rates.
