HASTE MAKES WASTE: ACCELERATED MOLT ADVERSELY AFFECTS THE EXPRESSION OF MELANIN-BASED AND DEPIGMENTED PLUMAGE ORNAMENTS IN HOUSE SPARROWS.

Haste makes waste: accelerated molt adversely affects the expression of melanin-based and depigmented plumage ornaments in house sparrows.

Many animals display colorful signals in their integument which convey information about the quality of their bearer.Theoretically, these ornaments incur differential production and/or maintenance costs that enforce their honesty.However, the proximate mechanisms of production costs are poorly understood and contentious in cases of non-carotenoid-b

Complementary Approaches for Enhancing Polystyrene Hydrophobicity: Additives Development and Replication of Micro/Nanotextures

This work aims at developing polymer surfaces with enhanced hydrophobicity by controlling both the surface chemistry and the surface structure.As a first step, a chemical surface modification is achieved by the incorporation of a synthetized tailored fluorinated copolymer, named POISE-a (Polymer prOcessing Interface SexFlesh StabilizEr), in a comme
