Epidamaeus hexatuberculatus sp. n. (Oribatida: Damaeidae) is described from Russia. The new species similar to E. nortoni Bayartogtokh, 2004 and tritylos Behan-Pelletier et Norton, 1983 but differs both by the absence of enantiophyses E2 V, presence mediosejugal enantiophysis, narrowly phylliform interlamellar seta tubercle-like, rounded distally discidium, localization prodorsobasal tubercle Da.
Three new species of oribatid mites of the family Oppiidae (Oribatida, Oppioidea), belonging to the genera/subgenera Tripiloppia Hammer, 1968 and Lanceoppia (Baioppia) Luxton, 1985, are described from Central Otago, South Island, New Zealand. Tripiloppia frigida sp. nov. is morphologically similar to T. dalenii Hammer, 1968, but differs from the latter by the lanceolate bothridial setae, five p...

Stereological methods for serial sections traditionally assume that the sections are exactly equally spaced. In reality, the spacing and thickness of sections can be quite irregular. This may affect the validity and accuracy of stereological techniques, especially the Cavalieri estimator of volume. We present a new formula for the accuracy of the Cavalieri estimator that includes the effect of ...
The relationship between species richness and the occupation of niche space can provide insight into the processes that shape patterns of biodiversity. For example, if species interactions constrained coexistence, one might expect tendencies toward even spacing within niche space and positive relationships between diversity and total niche volume. I use morphological diversity of passerine bird...
Spatial order is the organizing principle of the visual areas in the brain. But to what extent does this spatial mapping help us see where things are? Observers trained to perfectly recall the spatial order of seven items presented simultaneously for 5 s were asked to report their order when flashed for only 150 ms. We found that the capacity for perceiving the order of these brief stimuli was ...
We measured the supernumerary spacing parameter of the first- and second-order rainbows of two glass rods, each having an approximately elliptical cross section, as a function of the rod's rotation angle. We attribute large fluctuations in the supernumerary spacing parameter to small local inhomogeneities in the rod's refractive index. The low-pass filtered first-order rainbow experimental data...
Members of the newly identified claudin gene family constitute tight junction (TJ) strands, which play a pivotal role in compartmentalization in multicellular organisms. We identified oligodendrocyte-specific protein (OSP) as claudin-11, a new claudin family member, due to its sequence similarity to claudins as well as its ability to form TJ strands in transfected fibroblasts. Claudin-11/OSP mR...
