AbstractMountains provide a timely opportunity to examine the potential effects of climate change on biodiversity. However, nature conservation in mountain areas have mostly focused on the observed part of biodiversity, not revealing the suitable but absent species—dark diversity. Dark diversity allows calculating the community completeness, indicating whether sites should be restored (low completeness) or conserved (high completeness). Functional traits can be added, showing what groups should be focused on. Here we assessed changes in taxonomic and functional observed and dark diversity of epiphytic lichens along elevational transects in Northern Italy spruce forests. Eight transects (900–1900 m) were selected, resulting in 48 plots and 240 trees, in which lichens were sampled using four quadrats per tree (10 × 50 cm). Dark diversity was estimated based on species co-occurrence (Beals index). We considered functional traits related to growth form, photobiont type and reproductive strategy. Linear and Dirichlet regressions were used to examine changes in taxonomic metrics and functional traits along gradient. Our results showed that all taxonomic metrics increased with elevation and functional traits of lichens differed between observed and dark diversity. At low elevations, due to low completeness and harsh conditions, both restoration and conservation activities are needed, focusing on crustose species. Towards high elevations, conservation is more important to prevent species pool losses, focusing on macrolichens, lichens with Trentepohlia and sexual reproduction. Finally, dark diversity and functional traits provide a novel tool to enhance nature conservation, indicating particular threatened groups, creating windows of opportunities to protect species from both local and regional extinctions.

AbstractLeaf phenology based classification of woody species into discrete evergreen and deciduous categories is widely used in ecology, but these categories hide important variation in leaf phenological behaviour. Few studies have examined the continuous nature of deciduousness and our understanding of variation in quantitative estimates of leaf shedding behaviour and the causes and consequences of this is limited. In this study we monitored leaf phenology in 75 woody species from a seasonally dry tropical forest to quantify three quantitative measures of deciduousness, namely: maximum canopy loss, duration of deciduousness, and average canopy loss. Based on proposed drought tolerance and drought avoidance strategies of evergreen and deciduous species, respectively, we tested whether the quantitative measures of deciduousness were related to leaf functional traits. Additionally, to understand the functional consequences of variation in deciduousness we examined relationships with the timing of leaf flushing and senescing. We found wide and continuous variation in quantitative measures of deciduousness in these coexisting species. Variation in deciduousness was related to leaf function traits, and the timing of leaf flushing. Along a continuous axis ranging from evergreen to deciduous species, increasing deciduousness was associated with more acquisitive leaf functional traits, with lower leaf mass per area and leaf dry matter content, and greater leaf nitrogen content. These results indicate that the continuous nature of deciduousness is an important component of resource acquisition strategies in woody species from seasonally dry forests.

Abstract. Syamsuwida D, Aminah A. 2020. Phenology and potential reproduction of turi (Sesbania grandiflora) at Cibinong, Bogor, Indonesia. Nusantara Bioscience 12: 13-20. Turi (Sesbania grandiflora (L.) Pers.) is one of a prospectus energy woody species to be developed in establishing renewable energy base forest plantation. The development of this species cannot be separated from the basic information of its reproductive biology. The study was aimed to evaluate flowering phenology and reproductive potency of S. grandiflora so that information could be elaborated to estimate the fruit production potential produced. The research method was carried out by direct observation of samples of flowering trees. Data were analyzed descriptively. The number of tree samples observed for flower and fruit development and reproductive success of 10 trees, from each tree were observed three flowering branches distinguished from the west and east branches. The results showed that S. grandiflora did not experience generative bud dormancy so that flower initiation was thought to occur throughout the year and could flower and bear fruit throughout the year. S. grandiflora at the observation location has a flowering-fruiting development cycle of about 3-4 months which begins with the emergence of generative bud at the time of the observation in April and developed into flower shoot in the same month. Blooming flower (anthesis) in May, develop into young fruit in June. Mature fruits can be harvested in June-July. The reproductive potency of S. grandiflora was low with a value of fruit set (fruit/flower ratio) at the eastern and western branches were 19% ± 0.07 and 17%±0.06 and seed set (seed/ovule ratio) of 87% ± 0.12 and 83% ± 0.16, respectively. Reproductive success was 18% ± 0.07 for the eastern branches and 17% ± 0.05 for the western branches. Most reproductive variables of S. grandiflora did not show a significant difference between the eastern and western branches (P>0.05), except for fruit number (P<0.05).
