“…O tipo de solo e as variações climáticas de cada região são fatores que podem infl uenciar não só no período, mas também a intensidade dos eventos fenológicos das espécies vegetais de modo que possam ser encontrados resultados distintos. Além disso, essa variação fenológica pode fazer com que os eventos se correlacionem de diferentes formas com variáveis climáticas e essa variação pode ser observada comparando este estudo com o de Azevedo et al (2014).…”

ESTRATÉGIAS FENOLÓGICAS REPRODUTIVAS DE Xylopia aromatica (LAM.) MART. (ANNONACEAE) EM ÁREA DE CERRADORESUMO: Apesar dos esforços empreendidos nos últimos anos, os dados sobre a fenologia das espécies do Cerrado são fragmentários e mesmo X. aromatica sendo amplamente distribuída sua fenologia é desconhecida. Neste sentido, buscou-se avaliar sua fenologia reprodutiva em um fragmento de Cerrado no Município de Rio Verde e correlaciona-la com as variáveis climáticas. Marcou-se 20 indivíduos para serem observadas mensalmente as fenofases: botão, flor aberta, fruto imaturo e maduro. Para as análises utilizou-se o percentual de Fournier, método de presença/ausência e correlação de Spearman. A emissão de botões ocorreu de modo irregular e os mesmos estiveram presentes tanto no período seco quanto no chuvoso de modo a não se correlacionar com nenhuma das variáveis. A floração ocorreu de forma distribuída ao longo do estudo se correlacionando de modo negativo apenas com a umidade relativa. A frutificação ocorreu no período seco e na transição do período seco para o chuvoso, correlacionada negativamente com a precipitação e umidade. Os frutos amadureceram nos últimos meses da estação seca e primeiros da chuvosa, se correlacionando apenas com a umidade. O ciclo reprodutivo de X. aromatica não é influenciado fortemente pelas variáveis climáticas e o fato de se correlacionar negativamente com a precipitação e umidade sugere que a espécie foi adaptada de modo a otimizar a polinização e dispersão de frutos. REPRODUCTIVE PHENOLOGICAL STRATEGIES OF Xylopia aromatica (LAM.) MART. (ANNONACEAE) IN CERRADO AREAABSTRACT: Despite efforts in recent years, data on the phenology of Cerrado species are fragmentary, and even X. aromatica being widely distributed, its phenology is unknown. In this sense, we sought to evaluate their reproductive phenology in a fragment of Cerrado in Rio Verde Municipality and correlate it with climatic variables. 20 individuals were marked to be subject to monthly phenological phases observation: bud, open flower, immature and mature fruit. For the analysis we used the percentage of Fournier, method of presence/ absence and Spearman correlation. The emission of buds occurred irregularly and was present in both the wet and in the dry period, not correlating with any of the climatic variables. Flowering occurred distributed throughout the study, negatively correlated only with relative humidity. Fruitification occurred in the dry season and in the transition from dry to rainy season, negatively correlated with rainfall and humidity. The fruits matured in the last months of the dry season and first months of the rainy season, correlating only with moisture. The reproductive cycle of X. aromatica is not strongly influenced by climatic variables and the fact that it is negatively correlated with precipitation and humidity suggests that the species was adapted to optimize pollination and dispersal of fruit.

“…In the tropical region, with high relative air humidity and no pronounced dry season, riparian forest species have been reported to flower mostly when air temperature changes from cool to warm (Cascaes et al, 2013). On the other hand, in the tropical region where two seasons (wet and dry) are clearly defined, flowers are found to bloom mainly in the dry season and produce fruits in the wet season (de Azevedo et al, 2014). In addition, Savannas riparian species were found to have flowering and fruiting periods in the wet season (Silva et al, 2011).…”

“…Plant reproductive events correlate with climatic factors, such as rainfall, temperature, photoperiod, and soil moisture (Elliot et al, 1994;Kikim & Yodava, 2001;Silva et al, 2011;Sulistyawati et al 2012;Cascaes et al, 2013;de Azevedo et al, 2014). In addition, biological factors, pollinators, dispersers, predators, and competitors, potentially influence plant cycles phenomena (Elliot et al, 1994, Cascaes et al, 2013.…”

The objective of this study was to investigate the duration of flowering and fruiting and the growth of riparian species in the natural forest along Phra Prong River, Watthana Nakhon District, Sa Kaeo province. The occurrence of flowering and fruiting was recorded every month from February 2015 to January 2016 (12 months) along a 7km distance of the riversides. Sixty six species belonging to 36 families were seen flowering and fruiting in this study. They were observed during February – April. The peak of flowering and fruiting occurred in March (early summer). Hydnocarpus anthelminthicus, Uvaria rufa, and Combretum latifolium had a long lasting flowering and fruiting period. Oxystelma esculentum, Capparis micracantha, Connarus cochinchinensis, Derris scandens, and Ficus racemosa produced flowers and fruits more than once a year. Those species may play an important role in availability of food resources for animals in the riparian forest. The appropriate time to collect seeds in Phra Prong riparian forest starts from February and lasts until August. The germination test indicated that Xanthophyllum lanceatum and Crateva magna had a high germination rate, about 70%. Growth of some riparian species, including Cinnamomum iners, Dipterocarpus alatus, Hydnocarpus anthelminthicus and Hopea odorata was monitored every three months from July 2015 to June 2016. Diameter growth of D. alatus was significantly higher during the wet season (Jul-Sep) than other seasons. In contrast, the rest of the species showed no significant differences among monitoring periods. Height growth rate of C. iners was significantly highest late in the dry period (Jan-Mar).

“…Despite the lack of studies on the vegetation of these veredas, we can infer that, due to biggest rise time, the northern veredas of Minas Gerais are in a more advanced stage of development. Nonetheless, the variation of vegetal cover can be a reflex of productivity gap between the areas, of the human disturbance or by the influence exerted by the vegetation domains since that the veredas of north of Minas Gerais are in an ecotonal area (Azevedo et al, 2014). Hence, more researches regarding ecological processes in veredas seem to be necessary in order to clarify these issues.…”

“…The Cerrado biome (Brazilian Savanna) is identified as one of the richest world's ecosystems, covering 21% of the country (about 2 million km²) and has more than 55,000 cataloged species plants, with a total of 5% of the world's biodiversity (Padovesi-Fonseca et al, 2015). The high biodiversity is mainly related to its connection with other Brazilian biomes, thereby generating biogeographic zones of tension (Azevedo et al, 2014). In addition, biodiversity is also due to its great environmental heterogeneity, the variation of soil and its characteristics (chemical composition, depth, type of drainage), favoring the diversity of environments and supporting various vegetation types that alternate in the landscape (Klink and Machado, 2005).…”

AbstractThe Mauritia flexuosa L. f. (Arecaceae) palm swamps (known as veredas in Brazil) are hygrophilous communities associated with hydromorphic soils in areas of headwaters, and feature special importance for water and biodiversity maintenance in the Cerrado biome. In northern Minas Gerais, the veredas have more complex structure and floristic composition in comparison with the veredas located in other parts of central Brazil, in the same biome. However, these areas are less studied and suffering various environmental impacts, which can uncharacterize them even before they are properly known. In the present work, a literature review was carried out, in which the age and the development of vegetation in the veredas of central Brazil and north of Minas Gerais were addressed. The conservation status and the importance of these areas for the biome were also discussed. Hence it was concluded that the veredas of the north of Minas Gerais are older than the veredas of central Brazil, suggesting that they are in a more advanced stage of ecological succession. However, many factors can influence the floristic composition and structure of these plant communities, requiring further studies involving ecological processes in veredas in order to elucidate those matters.
