Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
The moss genus Ochrobryum was chosen for this phenological study because of its wide range in the Brazilian territory markedly in Cerrado areas and there, without ecological studies and a significant number of samples in SP Herbarium. We analyzed 302 exsiccatae (totaling 906 individuals - three individuals per exsiccatae), and observed phenological patterns with alternance of the reproductive structures within the seasonal periods of the year. The sexual reproduction in Ochrobryum is highly related to the rainy periods and the asexual reproduction present uninterruptedly with an increase in the dry season. Our results demonstrate that Ochrobryum has a seasonal alternation of colonization strategies.
RESUMO
O gênero de musgos Ochrobryum foi escolhido para este estudo fenológico porque possui uma ampla distribuição no Brasil, especialmente nas áreas de Cerrado; nunca foi estudado do ponto de vista ecológico e possui número significativo de amostras no Herbário SP. Nós analisamos 302 exsicatas (totalizando 906 indivíduos - três indivíduos por exsicata), e encontramos padrões fenológicos e alternância de estruturas reprodutivas em relação a sazonalidade. A reprodução sexual em Ochrobryum está relacionada com os períodos chuvosos e a reprodução assexual ocorre em todas as épocas do ano com aumento na estação seca. Nossos resultados demonstram que Ochrobryum alterna seu potencial de colonização sazonalmente.
