ABSTRACTVertebrate pigmentation patterns are highly diverse, yet we have a limited understanding of how evolutionary changes to genetic, cellular, and developmental mechanisms generate variation. To address this, we examine the formation of a sexually-selected male ornament exhibiting inter- and intra-specific variation, the egg-spot pattern ...

HISTORIOGRAPHIC STUDIES FROM REGIONAL AND ORNAMENTAL FEATURES OF EASTER EGGS PAINTING
The Journal of Ukrainian History, 2019The article deals with the national historiography in which problems of regional-ornamental peculiarities of easter eggs painting are highlighted. The purpose of the proposed research is the analysis of the existing sources related to the historiography of regional ornamental peculiarities of easter eggs painting as a type of decorative and applied ...

AbstractThe sexually selected egg colour hypothesis (SSECH) proposes that egg colouration is as a post‐mating sexually selected signal of female phenotypic quality, maintained by a higher allocation of paternal care. Similarly, some female traits can reflect genetic quality or condition and males could use this information in mate choice or in ...

The leaf hopper fauna of ornamental honey locust, Gleditsia triacanthos L., was studied in south-central Pennsylvania. Detailed life history information was obtained on Macropsis fumipennis (Gillette & Baker) and Stragania apicalis (Osborn & Ball), two species restricted to honey locust, and on Orientus ishidae (Matsumura), known to feed on several ...

The external ornamentations of the cysts in anostracans are often characterized by crests and ridges. However, their variation cannot be properly quantified by traditional morphometrics. We propose a fractal-based analysis through box-counting to evaluate and compare differences between groups.

The use of cultured copepods in intensive fish larviculture has involved both calanoids and harpacticoid but the best results have been obtained using calanoid copepods which have a higher content of HUFAs, are entirely pelagic and usually have very small naupliar stages which are more readily captured by fish larvae with small gapes at first feeding ...
