“…For F. citrifolia and F. americana subspecies guianensis form mathewsii fruiting occurred four times a year. Twice yearly fig production for F. obtusifolia was also observed in the studies of Ballestrini et al (2011) in Venezuela and Panama. In the same way, Cerezini et al (2007) observed that fig production in F. citrifolia may occur continuously throughout the year.…”

An understanding of the complex ecological interaction between fig wasps and their host plants in Amazonia requires previous knowledge of their distribution and diversity. The objective of this study was to describe the composition and structure of the wasp community associated with four species of Ficus in the municipal area of Manaus, Amazonas, Brazil. A total of 600 syconia from four species were collected. The study species were: Ficus obtusifolia Kunth; Ficus citrifolia Mill; F. americana subspecies guianensis Desv. form mathewsii; and F. americana subspecies guianensis Desv. form parkeriana. Statistical analyses were used to examine the relationship between fig wasp diversity and syconium diameter, and the effect of non-pollinating wasps on numbers of pollinators and seeds. Forty three species of fig wasp were identified, distributed across seven genera (Pegoscapus, Idarnes, Aepocerus, Physothorax, Anidarnes, Heterandrium , Eurytoma). Idarnes (carme group) was the wasps genus non-pollinator with greatest number of individuals with the greatest number of infested syconia (7409 wasps in 376 syconia). Analysing non-pollinating wasp diversity in relation to fig diameter, a significant difference was observed between the four fig species. Ficus citrifolia and F. americana subspecies guianensis form mathewsii had the smallest diameter but the greatest diversity of fig wasp. Ficus obtusifolia was the only species in which the non-pollinating wasps had a significant negative effect on the number of Pegoscapus sp. and on seed production.

“…The leaf phenologies of male and female Mearns fig trees in Frog Rock Trail and Jialeshuei were similar, suggesting that plant variations mainly triggered by climate 10 , 20 , 23 , 26 , 27 and not closely related to sexual distinction. In our analysis of leaf phenology and meteorological factors, we found that the mature leaf abundance of Mearns fig in Frog Rock Trail negative correlated with rainfall significantly, whereas in Jialeshuei, the mature leaf abundance negatively correlated with both rainfall and temperature.…”

“…However, in tropical or dry areas, rainfall cycle is a key component of plant reproduction 38 . Indeed, several studies on the phenology of Ficus have found that the abundance of tender leaves, mature leaves, and Phase A figs were correlated positively with rainfall 18 , 23 , 25 , 26 . Although the results of the present study differ from those of previous scholars, this difference does not imply the negative influence that water exerts on Mearns fig phenology.…”

Mearns fig grows at the edge of coastal vegetation on uplifted coral reefs, its population and mutualistic-pollinators are susceptible to the influence of extreme weather. To determine the phenology of Mearns fig and the effects of various weather events under small-scale topographic differences, phenology was conducted for 3 years and 7 months. Results showed that Mearns figs had multiple leaf and fig productions year-round. Topographic effects caused population in Frog Rock Trail and Jialeshuei, which are less than 10 km away from each other, to exhibit different phenological patterns after experiencing severe weather events. Northeast monsoons led the Jialeshuei population to show low amounts of leaves and figs in winter and the phenological production was also susceptible to disturbances by typhoons in summer. Fig reproduction in such environment was disadvantageous to maintain pollinators. Besides, topographic complex in microhabitat of Frog Rock Trail protected some individuals from these same events thus safeguard population’s survival. The phenology of Mearns fig would respond to the weather events sensitively, which serve as references for estimating the mutualism system, and as indicators of climate change.

“…[27]. A strong correlation was found between sum of growing degree days and leaf and shoot growth in a temperate tree species, Chilean hazelnut (Gevuina avellana Mol) [28], between day length and leaf phenology in the tropical species Ficus obtusifolia [29], and between leaf phenology of trees in the Atlantic forests and day length and temperatures [30]. The correlation of the expanded leaf stage development and rainfall was not as strong in 2007.…”

Comparative Leaf Phenology of White Oak and Northern Red Oak

2015

View full text Add to dashboard Cite

In the landscape, loss of interveinal tissue in developing leaves (leaf tatters) is common for white oak (Quercus alba L.), but not northern red oak (Quercus rubra L.). Previous research identified the cause of leaf tatters, as exposure of unfolding leaves, to low concentrations of chloroacetanilide herbicides. Both white oak and northern red oak were injured by these herbicides at the leaf unfolding stage. Reports from landowners suggest white oak is injured more often than red oak, leading us to theorize that white and northern red oak leaves emerge at different times, and white oaks were more likely to be at the leaf unfolding stage when chloroacetanilide herbicides are applied. A study of comparative leaf phenology of white and northern red oak was done at three sites in Urbana, IL. Identifying oak pairs was challenging, and at each location, four to six paired mature white oak and northern red oak trees were used to observe phenological events. Key development stages (swollen bud, leaf unfolding, or fully expanded leaf stages) were considered to have occurred when reached by greater than 50% of the canopy. Northern red oak expanded leaf stage occurred earlier when compared to white oak. Time between phenological events was similar for both species. Although northern red oak leaves emerged earlier, there was a range of emergence times within short distances. Difference
