Estrutura populacional, distribuição espacial e fenologia de Anacardium humile A. St.-Hil. (Anacardiaceae) em cerrado stricto sensu

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Este estudo analisou a estrutura de tamanho, a distribuição espacial e a fenologia dos indivíduos de uma população de Anacardium humile A. St.-Hil. em cerrado sentido restrito. Foram alocadas aleatoriamente quatro parcelas (100 × 100 m cada) na terra Quilombola Kalunga. Dentro das parcelas cada indivíduo foi contabilizado e teve mensurada a altura, diâmetro basal, quantidade de ramos e anotações quanto a sua localização e a presença de afloramentos rochosos. Para a fenologia, dezesseis indivíduos foram monitorados entre maio de 2016 a abril de 2017. Foram inventariados 417 indivíduos que resultaram na densidade média de 104.25 ind ha^-1 (± 60,35). A abundância de indivíduos foi maior nos afloramentos rochosos e o padrão de distribuição espacial foi do tipo agregado. A população é auto-regenerativa. As alterações fenológicas concentraram no período seco e foram influenciadas pelas menores taxas de precipitação, temperatura máxima e umidade relativa do ar.
