Organochlorine Pesticide Contamination and its Potential Effects on Eggshell Characteristics of Dickcissels (Spiza americana) [PDF]
Dickcissels (Spiza americana) are small, sparrow-like songbirds that nest in grasslands in the U.S. and winter in Venezuela. Fanners in Venezuela intentionally spray dickcissel flocks with organochlorine (DC) and other illegal pesticides in an attempt to

The effect of developmental stage on eggshell thickness variation in endangered falcons [PDF]
We compared eggshell thickness of hatched eggs with that of non-developed eggs in endangered falcon taxa to explore the effect of embryo development on eggshell thinning.

UAVs unveil the role of small scale vegetation structure on wader nest survival
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Optimization of Eggshell Calcium Use for Improving the Physical Quality of Whey Protein Isolate-based Edible Films [PDF]
Edible films based on biopolymers are increasingly popular as environmentally friendly and functional food packaging alternatives. One approach to improving the physical properties of edible films is by incorporating calcium derived from eggshell waste ...

Eggshells as hosts of bacterial communities: An experimental test of the antimicrobial egg coloration hypothesis [PDF]
AbstractOviparous animals have evolved multiple defenses to prevent microbes from penetrating their eggs and causing embryo mortality. In birds, egg constituents such as lysozyme and antibodies defend against microbial infestation, but eggshell pigments might also impact survival of bacteria.

ABSTRACT By combining theories of system thinking with a post‐humanist approach, we established a nexus between human and non‐human systems in the examination of systemic innovation. By doing so, we shed light on the interdependencies that exist between human and non‐human systems and contribute theoretically as well as methodologically to theories on ...

Eggshell coloration reflects both yolk characteristics and dietary carotenoid history of female mallards [PDF]
Summary Avian eggshell coloration has frequently been examined in a functional context (e.g. mimicry, camouflage), but in recent years, an interest has emerged in identifying the mechanisms that drive eggshell colour variation. Eggshell coloration is predominately caused by pigment deposition; one such pigment is the antioxidant biliverdin, and ...

Enlightened Romanticism: Mary Gartside’s colour theory in the age of Moses Harris, Goethe and George Field [PDF]
The aim of this paper is to evaluate the work of Mary Gartside, a British female colour theorist, active in London between 1781 and 1808. She published three books between 1805 and 1808.
