“…traits. Indeed, for more than two decades studies have suggested that the relationships among plant traits may be visualized as a network or correlogram, and sometimes analyzed using path analysis or structural equation models [21,26,[37][38][39][40][41][42][43]. Recent studies [40,44] have quantified parameters to describe the network topology and the interdependency of traits.…”

Functional traits are frequently used to evaluate plant adaptation across environments. Yet, traits tend to have multiple functions and interactions, which cannot be accounted for in traditional correlation analyses. Plant trait networks (PTNs) clarify complex relationships among traits, enable the calculation of metrics for the topology of trait coordination and the importance of given traits in PTNs, and how they shift across communities. Recent studies of PTNs provide new insights into some important topics, including trait dimensionality, trait spectra (including the leaf economic spectrum), stoichiometric principles, and the variation of phenotypic integration along gradients of resource availability. PTNs provide improved resolution of the multiple dimensions of plant adaptation across scales and responses to shifting resources, disturbance regimes, and global change. Rapid Advances in Data, Analyses, and Applications of Trait-Based Plant Ecology Plant functional traits, defined as those that influence growth, reproduction, and survival [1,2], are important indices for predicting how plants respond and adapt to changing environments across levels of organization, that is, from organs, to species, and to ecosystems [3,4]. Indeed, functional traits can contribute to the prediction of species' distributions, vital rates, and responses to climate change [5]. Highlights Most functional traits are multifunctional and adaptations to multiple selective pressures, complicating the use of traditional correlation and clustering approaches to establish their integration and relative mechanistic importance. New developments in the analysis and application of plant trait networks (PTNs) increase the resolution and inference of adaptations and responses of plants across scales. Communities vary in their constraints on given traits, resulting in variation in PTN topology, and the relative importance of component traits. PTNs provide a multidimensional approach for evaluating the adaptations and response of plants across lineages, life forms, ontogenetic stages, and environments.

Summary⍰ Modulation of stomatal development may be an acclimation response to low water availability. However, stomatal development plasticity has been assessed in very few species.⍰ We quantified leaf anatomy traits, including stomatal index (SI), density (SD), size (SS), and pore index (SPI), in response to water-deficit stress in river birch (Betula nigra L.), eastern redbud (Cercis canadensis L.), and silver maple (Acer saccharinum L.).⍰ Birch and redbud, but not maple, had reduced SPI in response to water deficit. The mechanism by which SPI reduction occurred (via SD or SS) varied among species and with severity of water stress. Despite reduced SPI in birch and redbud, anatomical changes were relatively small and had a minor to no effect on the theoretical maximum stomatal conductance. Furthermore, gas-exchange rates were equivalent to well-watered plants following media re-irrigation.⍰ In some tree species, stomatal development is downregulated in response to water deficit conditions. Stomatal development plasticity is facilitated by smaller or fewer stomata, depending upon the species and the intensity of the stress. Water-deficit-induced plasticity in stomatal development is species-specific, likely due to species adaptation to ecological niches.

“…The occurrence of both rainforest and savanna species in several speciose genera in the Neo‐ and Palaeotropics also makes the family an excellent system for the study of biome transitions, particularly in light of recent efforts to address responses of rain forests to climate change and of climatic tipping points for rain forests (Hirota & al., 2011; Flores & al., 2017). The family is also very interesting with regard to the evolution of dioecy, andromonoecy and androdioecy (Schneider & al., 2002; Schneider & Zizka, 2016, 2017) and the evolution of unique leaf venation networks (Schneider & al., 2017). The lack of information on phylogeny and monophyly of the up to now recognized major groups has also been an impediment to taxonomic progress.…”

Targeted capture of nuclear genes increasingly contributes to unravelling phylogenetic relationships that hitherto remained unresolved because of limitations of traditional Sanger sequencing. In particular, the study of tropical plant families has been compromised because they often rely on highly degraded DNA obtained from herbarium specimens. One such example is the pantropical Ochnaceae, which comprises 33 genera and approximately 550 species, occurring mostly in savannas and moist tropical forests. Here, we developed a set of baits covering about 660,000 bp from 275 nuclear genes used for the targeted enrichment based on all but one genus and more than 250 species. Using this novel dataset, we resolved the phylogenetic backbone of Ochnaceae, including that of Ochninae, and we established new relationships. Most importantly, our findings highlight that the neotropical and palaeotropical taxa of Sauvagesia form independent clades, requiring the re-erection of formerly separate genera. Ouratea and Ochna (both Ochninae), by far the most species-rich genera and represented by 120 and 41 species, respectively, came out as monophyletic. In contrast, the third-most species-rich genus, Campylospermum, is polyphyletic in two distinct clades. Ouratea, the only neotropical genus of Ochninae, was sister to the five palaeotropical genera of this subtribe. The bait kit developed in this study proved to be particularly useful for unravelling relationships within Ochninae, which includes about two-thirds of the species diversity in the family.
