Colour-variation in the Guinea-fowl [PDF]
Nature, 1902 As this bird is such a recent addition to the poultry-yard (for, although known to the Romans, it went out of domestication in the Middle Ages) and has not been selectively bred by fanciers, its spontaneous variations are particularly interesting. Here, in India, where guinea-fowls are much bred, several well-defined types of coloration constantly ...

Using Local Expert Knowledge to Measure Prices: Evidence From a Survey Experiment in Vietnam
Review of Development Economics, EarlyView.ABSTRACT Many countries lack spatially disaggregated consumer price data needed to estimate real inequality and spatial patterns of poverty.

The Australian Journal of Anthropology, EarlyView.Abstract Ethnographers observe and engage the field. They live with, play with, eat with, dance with, feel with, and, increasingly, write or film with their interlocutors. But most of all, they listen and converse. As they enter the lingual ecology of their hosts through a range of practices of communication, ethnographers begin a multi‐faceted journey

Biological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
