Abstract
conhecimento fenológico papel fundamental na conservação de ecossistemas, comunidades e populações. Os objetivos deste estudo são monitorar e detectar as fenofases de E. pyriformis , em área de restauração florestal, no município de Dois Vizinhos, Paraná. Observaram-se ciclos fenológicos de 12 árvores matrizes, quinzenalmente, durante 24 meses. Houve correlação entre os parâmetros fenológicos vegetativos e as variáveis climáticas de temperatura local e pluviosidade, evidenciada no aumento da produção foliar em meses de temperaturas mais elevadas. Os maiores picos de brotação ocorreram no mês de outubro, variando de 67% a 83% nos anos de 2015 e 2016, respectivamente. A queda foliar mostrou-se inversamente proporcional à brotação, com maiores incidências de queda foliar no outono e no inverno, chegando a 73% em março e 75% em agosto de 2016. Em período de geadas, não houve brotação. Foram encontradas maiores incidências de brotação durante o verão e baixas ABSTRACT E. pyriformis (uvaia) is a fruit species, used in ecological restoration, urban afforestation, for medicinal purposes, food production, maintenance of wild fauna.

期刊介绍:
Bothalia: African Biodiversity & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhance the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa.
The journal was previously published as Bothalia, and had served the South African botanical community since 1921. However the expanded mandate of SANBI necessitated a broader scope for the journal, and in 2014, the subtitle, African Biodiversity & Conservation was added to reflect this change.
