Spin-density-wave transition of (TMTSF)$_2$PF$_6$ at high magnetic fields [PDF]
The transverse magnetoresistance of the Bechgaard salt (TMTSF)$_2$PF$_6$ has been measured for various pressures, with the field up to 24 T parallel to the lowest conductivity direction c$^{\ast}$.

Megachile (Megachile) montivaga (Hymenoptera: Megachilidae) nesting in live thistle (Asteraceae: Cirsium) [PDF]
Although Megachile Latreille (leafcutter bees) are well known for their diverse nesting habits, records of the genus nesting in live plants are rare. Here, we report the widespread Megachile (Megachile) montivaga Cresson nesting in live thistle (Cirsium

Oxidative Stress Is a Potential Cost of Synchronous Nesting in Olive Ridley Sea Turtles
Olive ridley sea turtles, Lepidochelys olivacea, exhibit a polymorphic reproductive behavior, nesting solitarily or in mass aggregations termed “arribadas”, where thousands of individuals nest synchronously.

Adaptive latitudinal variation in Common Blackbird Turdus merula nest characteristics [PDF]
Nest construction is taxonomically widespread, yet our understanding of adaptive intraspecific variation in nest design remains poor. Nest characteristics are expected to vary adaptively in response to predictable variation in spring temperatures over

The aim of the research was to examine how the nest selection preference of laying hens with different genotypes differed, the proportion of eggs laid in the litter, eggs laid in the upper and bottom nests, and the number and duration of nest visits. The

Experimental Electronic Structure and Interband Nesting in BaVS_3 [PDF]
The correlated 3d sulphide BaVS_3 is a most interesting compound because of the apparent coexistence of one-dimensional and three-dimensional properties. Our experiments explain this puzzle and shed new light on its electronic structure.

Territorial defense of the red-whiskered bulbul, Pycnonotus jocosus (Pycnonotidae), in a semi-wild habitat of the bird farm [PDF]
The territorial behavior of the red-whiskered bulbul, Pycnonotus jocosus, was studied in the semiwild habitat of a bird farm compound in the District of Chana, Songkhla Province, the south of Thailand.

: Because wild turkey (Meleagris gallopavo; hereafter turkey) hens and nests suffer from great mortality rates, accurately identifying turkey nest predators is important to wildlife managers, especially in areas where nest predation is thought to limit ...

Frustration of antiferromagnetism in the t-t'-Hubbard model at weak coupling [PDF]
The perfect-nesting instability towards antiferromagnetism of the Hubbard model is suppressed by next-nearest neighbor hopping t'. The exact asymptotic behavior of the critical coupling U_c(t') at small t' is calculated in dimensions d=2,3 and infinity ...

A unique nest-protection strategy in a new species of spider wasp.
Hymenoptera show a great variation in reproductive potential and nesting behavior, from thousands of eggs in sawflies to just a dozen in nest-provisioning wasps. Reduction in reproductive potential in evolutionary derived Hymenoptera is often facilitated
