Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

The Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

DYNAMICS OF WAITING IN PIGEONS [PDF]

Journal of the Experimental Analysis of Behavior, 1996
Two experiments used response‐initiated delay schedules to test the idea that when food reinforcement is available at regular intervals, the time an animal waits before its first operant response (waiting time) is proportional to the immediately preceding interfood interval (linear waiting; Wynne & Staddon, 1988).

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

British Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.
