“…We saw variability in flowering and fruiting patterns among species within the same forest site, presumably associated with selection for responses to differing environmental drivers. This may be expected when different functional traits mediate the response to environmental drivers of phenological patterns: for example, different animal-plant relationships (Takenoshita et al 2008), different modes of seed dispersal (e.g., wind-dispersed seeds tend to ripen during drier periods and fleshy fruits in wetter ones: Chapman et al 2005), or differences in endogenous factors mediating the response (which may reflect genetic differences: Staggemeier et al 2015). Although our study is the first to present and compare the range of phenological profiles at tropical forest sites across Africa, the question of why predominant cycle length varies across the continent remains unanswered.…”

Annual cycles are the most common reproductive strategy in African tropical tree communities

We present the first cross‐continental comparison of the flowering and fruiting phenology of tropical forests across Africa. Flowering events of 5446 trees from 196 species across 12 sites and fruiting events of 4595 trees from 191 species across 11 sites were monitored over periods of 6 to 29 years and analyzed to describe phenology at the continental level. To study phenology, we used Fourier analysis to identify the dominant cycles of flowering and fruiting for each individual tree and we identified the time of year African trees bloom and bear fruit and their relationship to local seasonality. Reproductive strategies were diverse, and no single regular cycle was found in >50% of individuals across all 12 sites. Additionally, we found annual flowering and fruiting cycles to be the most common. Sub‐annual cycles were the next most common for flowering, whereas supra‐annual patterns were the next most common for fruiting. We also identify variation in different subsets of species, with species exhibiting mainly annual cycles most common in West and West Central African tropical forests, while more species at sites in East Central and East African forests showed cycles ranging from sub‐annual to supra‐annual. Despite many trees showing strong seasonality, at most sites some flowering and fruiting occurred all year round. Environmental factors with annual cycles are likely to be important drivers of seasonal periodicity in trees across Africa, but proximate triggers are unlikely to be constant across the continent.

“…( sensu Lucas et al , 2011) is now considered a large genus taken in a loose sense, composed of four traditional genera ( Myrcia DC., Marlierea Cambess, Calyptranthes Sw . and Gomidesia O.Berg), comprising 753 species [1], that are now in process of synonimization based on recent molecular findings [6,7,8]. According to Rosario and coworkers, many species of these four genera found in the Amazon still need phylogenetic analysis [9].…”

Myrcia is one of the largest genera of the economically important family Myrtaceae. Some of the species are used in folk medicine, such as a group known as “pedra-hume-caá” or “pedra-ume-caá” or “insulina vegetal” (insulin plant) that it is used for the treatment of diabetes. The species are an important source of essential oils, and most of the chemical studies on Myrcia describe the chemical composition of the essential oils, in which mono- and sesquiterpenes are predominant. The non-volatile compounds isolated from Myrcia are usually flavonoids, tannins, acetophenone derivatives and triterpenes. Anti-inflammatory, antinociceptive, antioxidant, antimicrobial activities have been described to Myrcia essential oils, while hypoglycemic, anti-hemorrhagic and antioxidant activities were attributed to the extracts. Flavonoid glucosides and acetophenone derivatives showed aldose reductase and α-glucosidase inhibition, and could explain the traditional use of Myrcia species to treat diabetes. Antimicrobial and anti-inflammatory are some of the activities observed for other isolated compounds from Myrcia.

“…Some phenological studies have emphasized the importance of considering the year as a continuum, working with angles and applying a linearization of angular variables before conducting linear statistical analyses (Table ). Staggemeier, Diniz‐Filho, and Morellato () first proposed an ordination metric to linearize angles, and further studies applied this approach with minor modifications (Chang‐Yang, Lu, Sun, & Hsieh, ; Seger, Duarte, Debastiani, Kindel, & Jarenkow, ; Silva, Silva, Carvalho, & Batalha, ; Staggemeier et al, ).…”

The high diversity of plant species in the tropics has revealed complex phenological patterns and reproductive strategies occurring throughout the year. Describing and analysing tropical plant phenology, and detecting triggers, demands to consider the circular nature of recurrent life cycle events and the use of appropriated statistical metrics. Here, we explore analytical pitfalls potentially affecting results of studies that do not consider the circular nature of phenology data when comparing resting and non‐resting systems, especially when accounting for phylogeny. We discuss definitions of the widely used first flowering date and revisit the literature on phylogenetic signal in plant phenology. We compare statistical analyses for tropical and temperate phenology by simulating communities with known phenological and phylogenetic structures. We demonstrate that ignoring the circular nature of phenological data underestimates the phylogenetic signal in plant phenology. Using the proposed circular transformation for non‐resting tropical ecosystems and resting temperate systems prevented errors, yielding precise comparisons. Synthesis. The analysis of both non‐resting and resting systems must consider the circularity of phenological events. Circular statistics is the appropriate approach to calculate phenological parameters, identify phylogenetic signal and assess drivers, allowing accurate cross‐comparisons of phenology across environments at large spatial scales.
