Genetic barcoding of museum eggshell improves data integrity of avian biological collections

Variability in Avian Eggshell Colour: A Comparative Study of Museum Eggshells

BACKGROUND The exceptional diversity of coloration found in avian eggshells has long fascinated biologists and inspired a broad range of adaptive hypotheses to explain its evolution. Three main impediments to understanding the variability of eggshell appearance are: (1) the reliable quantification of the variation in eggshell colours; (2) its perception by birds themselves, and (3) its relation...

Reassembling Ethnographic Museum Collections

This volume addresses fundamental questions about the nature, value, and efficacy of museum collections in a postcolonial world and the agency of indigenous people in their production. The book’s primary focus lies with those objects that, by way of their specific histories, have been defined as “ethnographic”; however, the question of the contexts in which things are defined as “art” as oppose...

Visual Topical Analysis of Museum Collections

Determination of insoluble avian eggshell matrix proteins.

The organic components of bones and other mineralized tissues have a high impact on the organization and deposition of calcium, and consequently influence the mechanical properties of those tissues. The extractable proteins of avian eggshells have been studied extensively and many of them have been identified; insoluble (non-extractable) proteins have been sparsely studied, however. In the work...

Molecular and morphological analyses of avian eggshell

Using ancient DNA (aDNA) extracted from eggshell of the extinct moa (Aves: Dinornithiformes) we determined the species composition and number of eggs found in a late thirteenth century earth oven feature at Wairau Bar (South Island, New Zealand) – one of New Zealand’s most significant archaeological sites. Mitochondrial and nuclear DNA signatures confirmed this oven feature contained fragments ...
