Use of anthropogenic structures for nesting by Loggerhead Shrikes

Avian Conservation and Ecology
As human activities continue to reshape ecosystems, reports of anthropogenic nest site use by birds are increasing. Although many of these reports focus on cavity nesting species using artificial nest boxes, many species also use buildings and other ...

Universality in percolation of arbitrary Uncorrelated Nested Subgraphs

, 2010
The study of percolation in so-called {\em nested subgraphs} implies a generalization of the concept of percolation since the results are not linked to specific graph process. Here the behavior of such graphs at criticallity is studied for the case where

Dispersive Gap Mode of Phonons in Anisotropic Superconductors [PDF]

, 2003
We estimate the effect of the superconducting gap anisotropy in the dispersive gap mode of phonons, which is observed by the neutron scattering on borocarbide superconductors.

Nest Architecture of Tetragona clavipes (Fabricius) (Hymenoptera, Apidae, Meliponini)

Sociobiology, 2016
The aim of this study was to describe the nest architecture of Tetragona clavipes colonies, and to compare its features with other stingless bee species.

Nesting, Sex Ratio and Natural Enemies of the Giant Resin Bee in Relation to Native Species in Europe

Insects, 2021
Megachile sculpturalis (Smith, 1853) is the first exotic bee species in Europe. Its remarkably fast expansion across this continent is leading to a growing concern on the extent of negative impacts to the native fauna.

Coupling of spin and orbital excitations in the iron-based superconductor FeSe(0.5)Te(0.5)

, 2010
We present a combined analysis of neutron scattering and photoemission measurements on superconducting FeSe(0.5)Te(0.5). The low-energy magnetic excitations disperse only in the direction transverse to the characteristic wave vector (1/2,0,0), whereas ...

Spin-Orbit Coupling and Magnetic Anisotropy in Iron-Based Superconductors

, 2017
We determine theoretically the effect of spin-orbit coupling on the magnetic excitation spectrum of itinerant multi-orbital systems, with specific application to iron-based superconductors.

Nesting aspects of the brown-winged schiffornis, Schiffornis turdina (Aves, Tityridae), with comments on nestling camouflage [PDF]

Zoologia (Curitiba)
Camouflage in nestlings has been documented for passerines of the genus Schiffornis, but limited reproductive details exist for the majority of species. Here, we present the first description of the nests and eggs of a threatened population of the brown ...

Linear magnetoconductivity in multiband spin-density-wave metals with nonideal nesting

, 2013
In several parent iron-pnictide compounds the resistivity has an extended range of linear magnetic field dependence. We argue that there is a simple and natural explanation of this behavior.

Further Observations on the Nesting Behavior of \u3ci\u3eLiris Argentatus\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

, 2017
A three-celled nest of Liris argentatus was excavated and examined in upstate New York. The nest was constructed from the terminus of an abandoned cicada-killer burrow and the cells contained 1-4 incompletely paralyzed Gryllus pennsylvanicus as prey. Two
