Direct archaeological evidence for Southwestern Amazonia as an early plant domestication and food production centre.

Southwestern Amazonia is considered an early centre of plant domestication in the New World, but most of the evidence for this hypothesis comes from genetic data since systematic archaeological fieldwork in the area is recent. This paper provides first-hand archaeobotanical evidence of food production from early and middle Holocene (ca. 9,000-5000 cal. BP) deposits at Teotonio, an open-air site located on a 40 m-high bluff on the south bank of the Madeira river. Such evidence includes the presence of local and exotic domesticates such as manioc (Manihot esculenta), squash (Cucurbita sp.) and beans (Phaseolus sp.), alongside edible fruits such as pequiá (Caryocar sp.) and guava (Psidium sp.) that point to the beginnings of landscape domestication. The results contribute to an ever-growing number of studies that posit southwest Amazonia as an important centre for early crop domestication and experimentation, and which highlight the longue-durée of human impacts on tropical forest biodiversity around the world.

A study on the introduction and institucionalization of rugby in brazil / Um estudo sobre a introdução e institucionalização do rugby no brasil

ABSTRACT This article aims to discuss, through documentary research, the introduction and institutionalization of rugby in Brazil specifically covering the period from 1891 to 1940. The historical approach involves the systematization of documentary research, using sources such as newspapers dating from the last decades the nineteenth century until the mid-twentieth and documents of the time. In order to build a mode narrative and demonstrate that despite the narrow base of participants and only recent media interest, The modality had an interested, although limited, group of participants and practitioners in Brazil since the early twentieth century.

RESUMO Este artigo tem como objetivo discutir, por meio da pesquisa documental, a introdução e institucionalização do rugby no Brasil englobando especificamente o período de 1891 a 1940. A abordagem histórica envolve a sistematização da pesquisa documental, utilizando como fontes jornais que datam entre as últimas décadas do século XIX até meados do XX e documentos da época. Com o objetivo de construir uma narrativa da modalidade e demonstrar que, apesar da restrita base de participantes e interesse apenas recente da mídia, a modalidade gozava de um grupo engajado, apesar de restrito, de participantes e praticantes no Brasil desde o início do século XX
