Flight feathers have evolved under selective pressures to be sufficiently light and strong enough to cope with the stresses of flight. The feather shaft (rachis) must resist these stresses and is fundamental to this mode of locomotion. Relatively little work has been done on rachis morphology, especially from a mechanical perspective and never at the nanoscale. Nano-indentation is a cornerstone...

New opacity distribution functions (ODFs) for several metallicities have been computed. The main improvements upon previous ODFs computed by Kurucz (1990) are: (1) the replacement of the solar abundances from Anders & Grevesse (1989) with those from Grevesse & Sauval (1998); (2) the replacement of the TiO lines provided by Kurucz (1993) with the TiO lines from Schwenke (1998), as distributed by...

Abstract European wild rabbit ( Oryctolagus cuniculus ) and red-legged partridge Alectoris rufa are main small game species of conservation concern in Mediterranean ecosystems. To date, their presence boar’s Sus scrofa diet factors driving consumption have been little investigated. A genetic metabarcoding approach was used on 80 boar faeces collected from four hunting estates devoted to during ...
