The ability of many domesticated animals to follow human pointing gestures to locate hidden food has led to scientific debate on the relative importance of domestication and individual experience on the origins and development of this capacity. To further explore this question we examined the influence of different prior training...
Domestic dogs’, Canis familiaris, responsiveness to human action has been a topic of scientific interest for almost two decades. However, are all breeds of domestic dog equally prepared to succeed on humanguided object-choice tasks? In the current study we compared three breeds of dog with distinct predatory motor pattern sequences...
Historically, Psychology education about disability focused narrowly on psychiatric and cognitive disabilities. Furthermore, disability tends to be viewed from the medical model, rather than the social model endorsed by disability scholars, which describes disability as primarily socially constructed. Course offerings for the Psychology departments of 98 top-ranked undergraduate programs in...
Self-assembly of recombinant proteins within the biosilica of living diatoms represents a means to construct functional materials in a reproducible and scalable manner that will enable applications that harness the inherent specificities of proteins to sense and respond to environmental cues. Here we describe the use of a silaffin-derived lysine-rich...
Although variations in insolation and emergent feedbacks among soil moisture,
vegetation, and soil cohesion are commonly invoked to explain topographic asymmetry that
depends on aspect, few studies have directly quantified the efficiency of regolith transport along
hillslopes of opposing aspect. We utilize meteoric ¹⁰Be concentrations in regolith (n = 74)...
Vegetation growing on the surface of a streambank has been shown to alter the shear stresses
applied to the boundary, but basic questions remain regarding the influence of vegetation and
streambank configurations on near-bank hydraulics. In the present study, Froude-scaled flume
experiments were used to investigate how changes in vegetation...
Perea, Duñabeitia, and Carreiras (2008) found that LEET stimuli, formed by a mixture of digits and letters (e.g., “T4BL3” instead of “TABLE”), produced similar priming effects as regular words. This finding led them to conclude that LEET stimuli automatically activate lexical information. The present study examined whether semantic activation occurs...
A new nematode species, Proparasitylenchus californicus n. sp., is described from the intertidal rove beetle Tarphiota geniculata (Mäklin) (Coleoptera: Staphylinidae) in California, USA. The new species differs from European representatives of the genus by possessing a cleft stylet in both sexes. The parasitic female is ovoviviparous and produces numerous juveniles...
The diatom Thalassiosira pseudonana was genetically modified to express biosilica-targeted fusion proteins comprising either enhanced green fluorescent protein (EGFP) or single chain antibodies engineered with a tetracysteine tagging sequence. Of interest were the site specific binding of (1) the fluorescent biarsenical probe AsCy3 and AsCy3e to the tetracysteine tagged fusion...
Geographic patterns of genetic variation in wild species reflect the interplay of ecological and evolutionary processes. We assessed genetic variation in three genomes across four North American diploid strawberry taxa, with special emphasis on the gynodioecious Fragaria vesca subsp. bracteata (A.Heller) Staudt. Specifically, we sequenced one chloroplast (rpoC2) and two...
