Flowering and fruiting show phenological complementarity in both trees and non-trees in mosaic-burnt floodable savanna.

The homogenization of fire regimes in a landscape may imply a temporal reduction in the availability of resources, such as flowers and fruits, which affect the fauna, as well as ecosystem services. We hypothesized that maintaining mosaic burning regimes, and thereby pyrodiversity, can diversify phenological patterns, ensuring year-round availability of flowers and fruits. Here we monitored open grassy tropical savanna phenology under different historical fire frequencies and fire seasons in a highly heterogeneous landscape in an Indigenous Territory in Brazil. We evaluated phenological patterns of tree and non-tree plants through monthly surveys over three years. These two life forms responded differently to climate and photoperiod variables and to fire. Different fire regimes led to a continuous availability of flowers and fruits, due to the complementarity between tree and non-tree phenologies. Late-season fires are supposed to be more devastating, but we did not detect a significant reduction in flower and fruit production, especially under moderate fire frequency. However, late burning in patches under high frequency resulted in a low availability of ripe fruits in trees. The fruiting of non-tree plants in patches under low fire frequency and early burning ensure ripe fruit, when there are practically no trees fruiting in the entire landscape. We conclude that maintaining a seasonal fire mosaic should be prioritized over historical fire regimes, which lead to homogenization. Fire management is best conducted between the end of the rainy season and the beginning of the dry season, when the risk of burning fertile plants is lower.

Sobre meu encontro com Lévi-Strauss / About my meeting with Levi-Strauss / Acerca de mi encuentro con Levi-Strauss

No presente artigo a autora faz um relato sobre entrevistas presenciais efetuadasdurante dez anos com Claude Lévi-Strauss, em Paris. O interesse da autora pelaspesquisas com populações indígenas de Mato Grosso e Mato Grosso do Sul, o início desuas atividades na Universidade Católica Dom Bosco, em Campo Grande, (MS) são oponto de partida para suas pesquisas que favoreceram a sua aproximação com oantropólogo. Outros fatos relevantes foram à leitura da obra de Claude Lévi-Strauss,Tristes Trópicos, com importantes informações sobre a região e seus índios, os estudosno Programa de Mestrado em Psicologia Social da Pontifícia Universidade Católica deSão Paulo-PUC/SP e doutorado em Paris 8- Sorbonne. As pesquisas com grupos Bororode MT e Kadiwéu de MS foram fatos que revelaram a maior afinidade e promoveram umagrande amizade entre a autora e o antropólogo. Os dois grupos étnicos marcaram iníciodos estudos de Claude Lévi-Strauss e sua Teoria – Antropologia Estrutural na década de30. Além da correspondência trocada entre ambos, vários encontros estão descritos no texto(AU)

The present article reports my friendship with Claude Lévi-Strauss, whichlasted for about the ten last years of his life. The author’s interest in researching theindigenous populations of Mato Grosso and Mato Grosso do Sul, the beginning of heractivities at Dom Bosco Catholic University, Campo Grande – MS, were the startingpoints for their research, such facts have favored their scientifical approach. Otherrelevant facts were the study of the work of Claude Lévi-Strauss, especially TristesTropiques, with important information about such Brazilian region and its Indians, studiesin Masters Program in Social Psychology at the Catholic University of São PauloPUCSPand Doctorate in Paris 8 - Sorbonne. The Bororo (MT) and Kadiwéu (MS)research groups revealed an affinity and promoted a strong friendship between theauthor and the anthropologist. The two ethnic groups have then marked the beginningof Claude Lévi-Strauss’s studies and his Theory - Structural Anthropology in the 30s.Besides the correspondence between them, several meetings are described in thetext(AU)

Sur ma rencontre avec Lévi-Strauss / About my meeting with Levi-Strauss / Acerca de mi encuentro con Levi-Strauss

Dans cet article je relate une relation de dix années d’amitié avec ClaudeLévi-Strauss. L’intérêt de l’auteure pour les recherches sur les populations indiennesdu Mato Grosso et du Mato Grosso du Sud, le début de ses activités au sein del’Université Catholique Dom Bosco à Campo Grande, MS ont été le point de départ deses recherches qui ont alors favorisé l’ approche entre l’auteure et l’anthropologue.Autres facteurs importants ont été la lecture de l’œuvre de Claude Lévi-Strauss, enparticulier Tristes Tropiques, contenant d’importantes informations sur la région ainsique sur ses indiens, les études du programme de Maîtrise en Psychologie Sociale dela pontificale Université Catholique de Sao Paulo-PUCSP et le doctorat à Paris 8-Sorbonne. Les recherches avec les groupes Bororo du MT et les Kadiwéu du MS ontrévélés la plus grande affinité et ont promu une grande amitié entre l’auteure etl’anthropologue. Les deux groupes ethniques ont marqué le début des études de ClaudeLévi-Strauss et de sa théorie-Anthropologie Structurale dans les années 30. Au-delà deleurs courriers échangés, diverses rencontres sont décrites dans le texte(AU)
