Abstract Aims Predictable and consistent differences between island mainland organisms arising from biased colonization/establishment are known as insular assembly rules. Baker's rule is a long‐standing predicting that the incidence of dioecy among early colonizers should be lower than source pool. While an established pattern floras, whether it results trait correlation or factors other insularity remains poorly understood. Here, I investigated relative roles insularity, climate, dioecy‐correlated traits in regulating across islands. Location Southwest Pacific. Methods amassed data set 485 plant species distributed eight archipelagos surrounding New Zealand. Trait was estimated using association algorithm. then used null model undirected network models to test for disentangle filtering undifferentiated colonizers. Results Some conformed rule, but not directly linked insularity. Instead, regulated by dioecy‐related traits, is, fleshy‐fruitedness woody habit, which turn were primarily driven climate. Conclusions Island rules can result correlation. partially with predictions rules, this resulted being largely excluded because climatic factors, Geographic variation breeding system determined endogenously, rather filtered characteristics islands per se.

Tropical forests occupy small coral atolls to the vast Amazon basin. They occur across bioregions with different geological and climatic history. Differences in area bioregional history shape species immigration, extinction diversification. How this effects local diversity is unclear. The Indonesian archipelago hosts thousands of tree whose coexistence should depend upon these factors. Using a novel dataset 215 forest plots, fifteen islands ranging from 120 785 000 km 2 , we apply Gaussian mixed models examine simultaneous environment, earthquake proximity, island bioregion for trees ≥ 10 cm diameter at breast height. We find that declines precipitation seasonality increases area. Accounting environment show westernmost Sunda has greater than Wallacea, which turn easternmost Sahul. However, when model includes activity (here proximity major earthquakes), differences are reduced. Overall, results indicate multi‐scale, current historic dictate diversity. These multi‐scale drivers not be ignored studying biodiversity gradients their impacts ecosystem function.

Although many fruit geometries resemble a solid of revolution, this assumption has rarely been rigorously examined. To test assumption, 574 fruits Canarium album (Lour.) DC. which appear to have an ellipsoidal shape, were examined determine the validity general avian-based egg-shape equation, referred as explicit Preston equation (EPE). The that C. geometry is revolution tested by applying volume formula for using EPE. goodness fit EPE was assessed adjusted root-mean-square error (RMSEadj). relationship between observed (Vobs) each fruit, measured water displacement in graduated cylinder, and predicted volumes (Vpre) based on also evaluated Vpre = slope * Vobs. All RMSEadj values smaller than 0.05, demonstrated profiles. 95% confidence interval vs. Vobs included 1.0, indicating there no significant difference data confirm are solids revolution. This study provides new approach calculating surface area geometrically similar fruits, can be extended other species with further explore ontogeny evolution angiosperm reproductive organs.

Abstract Fruit traits mediate animal-plant interactions and have to a large degree evolved match the sensory capacities morphology of their respective dispersers. At same time, fruit are affected by local environmental factors, which may affect frugivore-plant trait match. Temperature has been identified as major factor with strong effect on development fruits, is serious concern because rising threat global warming. Nonetheless, this primarily originates from studies domesticated cultivars in often controlled environments. Little known temperatures wild species implications could seed dispersal networks, including downstream consequences biodiversity ecosystem functioning. In case study five plant eastern Madagascar, we addressed using elevation-for-temperature approach examined whether temperature gradient systematically associated variation relevant for animal foraging selection. We sampled across representing 1.5–2.6 °C, corresponding IPCC projections. The results showed that most cases there was no significant evaluated, although some different effects, particularly chemical profiles. This suggests these warming within range alone not likely drive substantial changes networks. While systemic effects were found, also indicate differs lead mismatches specific interactions.

Abstract Aim Flower traits are critical to the mutualistic networks that underpin ecosystem function. However, broad‐scale drivers of flower unclear. Using megadiverse islands Malesia, we test three hypotheses: (1) size, openness and colourfulness (i.e. trend from white colourful flowers) will decrease with increasing temperature, but not precipitation seasonality. (2) increase island area, isolation. (3) Models parameterised by climate, rather than non‐climatic characteristics have greatest predictive capacity as climate affects both pollinator communities energetic/physiological constraints upon traits. Location Fourteen Malesian islands. Taxon Angiosperms. Methods We applied Bayesian phylogenetic models occurrence for >2500 species in 400 m elevation bands, across islands, a function trait interactions either climatic variables or characteristics. compare based on versus using Leave One Out‐Cross Validation. Results All six examined varied at least seasonality, area Flowers larger cold environments. The lowland tropics mostly inhabited flowered species. At high elevations, red pink more frequent whereas green purple drought‐prone seasonally dry tropics. declined seasonality increased performed best perianth length, flowers, flowers were better predicted Main Conclusions There relationships between gradients within Malesia. also left legacy current distributions.

Few plants have captured the imagination and palettes of world like those which bear edible fruits, providing novel insights into relationships between people. This special collection reviews research highlights unique challenges opportunities we face when studying, breeding, working to conserve these species. The 18 articles included here examine fruiting across diverse scales topics, from genome global sustainability, fruit morphology species' geographic distributions, yet they showcase only a fraction immense evolutionary, phenotypic, genomic diversity present in fruit‐bearing plants. Across collection, our hope is not offer importance but also provide taste future this area. We you enjoy fruits labor.

Our goal was to interrogate the idea that “mountain passes are higher in tropics” by investigating ecological and biogeographic drivers of elevational range‐sizes patterns among equatorial flora. We used herbarium records for 60 species‐rich plant families, representing 18 535 species total, estimate distributions over a 4500 m gradient. For each family, we estimated change average with increasing elevation (i.e. Rapoport's rule, abbreviated as ERR) quantified 15 metrics familial richness distribution, evolutionary age, affiliation. visualized covariation across families using phylogenetic principal components analysis (pPCA). then evaluated how family‐level ERR slopes correlated metric individually, well when multivariate techniques reduce dimensionality. hypothesized if long term climate stability millions years promotes habitat specialization, taxa longer‐term tropical affiliations, would expect smaller within lowland forests, greater range‐size expansion towards elevations, expressed positive slope. Conversely, variation growing conditions should promote larger, relatively consistent, at all sections an gradient, neutral results support this corollary because dichotomy observed relation distribution historical positioning. found Sundaland endemism, or restricted had slopes. Families stronger Sahul affiliation, montane centered richness, shallower, neutral, negative slopes, did clades temperate origins. Wallacea broader latitudinal distributions, cosmopolitanism, older age mixed results. conclude relative steepness slope is indicator taxonomic group's tolerance vulnerability contemporary change.
