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...
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...
According to the “social intelligence hypothesis,” species with complex social interactions have
more sophisticated communication systems. Giant otters (Pteronura brasiliensis) live in groups
with complex social interactions. It is likely that the vocal communication of giant otters is more
sophisticated than previous studies suggest. The objectives of the current study...
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)...
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...
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...
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...
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...
Despite the clear negative impact of high textbook costs on students, limits including space, funding, and policies prevent many academic libraries from fully supporting textbook collections. Partnering with other campus units on textbook lending requires creative thinking but can provide students access to other services in addition to the books...
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...
