Ground Penetrating Radar (GPR) forward and inversion methods are key techniques for studying radar imaging mechanisms investigating subsurface scenes. Efficiently interpreting wave data will facilitate the development of structure detection applications, especially in intricate plant root distribution. Existing models constrained by highly computational time-consuming process, making it difficult to be applied complex real-world scenarios. Inspired spatio-temporal properties during imaging, a spatial temporal fusion cycle U-shaped model named GPR-CUNet was proposed. The is more adapted transformation between permittivity distribution GPR B-Scan environment. Firstly, extract features from data, Spatio-Temporal Feature Fusion Module (STFM) based on CNN BiLSTM designed. Then, translation two identical networks with STFM module were constructed.

Although the above and belowground sizes shapes of plants strongly influence plant competition, community structure, plant-environment interactions, remain poorly characterized across climate regimes. We investigated relationships among shoot root system size climate. assembled analyzed, to our knowledge, largest global database describing maximum rooting depth, lateral spread, terrestrial - more than doubling Root Systems Individual Plants 5647 observations.

Abstract Plant diversity effects on community productivity often increase over time. Whether the strengthening of is caused by temporal shifts in species-level overyielding (i.e., higher diverse communities compared with monocultures) remains unclear. Here, using data from 65 grassland and forest biodiversity experiments, we show that strength at scale underpinned changes species yield. These trends are shaped plant ecological strategies, which can be quantitatively delimited functional traits. In grasslands, was associated increasing biomass resource-conservative time, characterized fast resource acquisition either decreasing or increasing. forests, differ when considering above- versus belowground strategies. Overyielding stem growth decreased for high light capture capacity but increased those soil capacity. Our results imply a different, potentially complementary, strategies beneficial maintaining time both ecosystems.

Summary Uncertainty persists within trait‐based ecology, partly because few studies assess multiple axes of functional variation and their effect on plant performance. For 55 species from two semiarid grasslands, we quantified: (1) covariation between economic traits leaves absorptive roots, (2) among traits, height, leaf size, seed mass, (3) relationships these species' abundance. Pairs analogous root were at least weakly positively correlated (e.g. specific area (SLA) length (SRL)). Two pairs such N content DMC moderately ( r > 0.5) whether grouped by site, taxonomic group growth form, or life history. Root diameter was with mass for all groups except annuals monocots. Species higher dry matter (LDMC) tended to be more abundant = 0.63). Annuals larger seeds 0.69). Compared global‐scale syntheses many observations mesic ecosystems, observed stronger correlations weaker SLA N, SRL N. In persistence may require coordination above‐ belowground dense tissues facilitate dominance.

Abstract Aim Functional trait space analyses are pivotal to describe and compare organisms' functional diversity across the tree of life. Yet, there is no single application that streamlines many sometimes‐troublesome steps needed build analyse spaces. Innovation To fill this gap, we propose funspace , an R package easily handle bivariate multivariate analyses. The six functions constitute can be grouped in three modules: ‘Building exploring’, ‘Mapping’ ‘Plotting’. building exploring module defines main features a (e.g. metrics) by leveraging kernel density‐based methods. mapping uses general additive models map how target variable distributes within space. plotting provides options for creating flexible publication‐ready figures representing outputs obtained from previous modules. We provide worked example demonstrate complete workflow. Main Conclusions will researchers working with traits life new tool explore: (i) any space, (ii) relationship between other biological or non‐biological factor might contribute shaping species' diversity.

Abstract Trait‐based ecology has already revealed main independent axes of trait variation defining spaces that summarize plant adaptive strategies, but often ignoring intraspecific variability (ITV). By using empirical ITV‐level data for two dimensions leaf form and function 167 species across five habitat types (coastal dunes, forests, grasslands, heathlands, wetlands) in the Italian peninsula, we found ITV: (i) rotated define space; (ii) increased variance explained by these (iii) affected functional structure target space. However, magnitude effects was rather small depended on type. Our results reinforce idea ITV is context‐dependent, calling careful extrapolations patterns traits spatial scales. Importantly, our study provides a framework can be used to start integrating into space analyses.
