Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels influence ecosystem properties. Variation in plant traits, trait syndromes, has proven useful for tackling many important questions at a range of scales, giving rise demand standardised ways measure ecologically meaningful traits. This line research been among most fruitful avenues...
Leaf mechanical properties strongly influence leaf lifespan, plant-herbivore interactions, litter decomposition and nutrient cycling, but global patterns in their interspecific variation underlying mechanisms remain poorly understood.We synthesize data across the three major measurement methods, permitting first analyses of mechanics associated traits, for 2819 species from 90 sites worldwide.Key measures resistance varied c. 500-800-fold among species.Contrary to a long-standing hypothesis,...
The search for predictions of species diversity across environmental gradients has challenged ecologists decades. humped-back model (HBM) suggests that plant peaks at intermediate productivity; low productivity few can tolerate the stresses, and high a highly competitive dominate. Over time HBM become increasingly controversial, recent studies claim to have refuted it. Here, by using data from coordinated surveys conducted throughout grasslands worldwide comprising wide range site...
Summary 1. We provide a brief overview of progress in our understanding introduced plant species. 2. Three main conclusions emerge from review: (i) Many lines research, including the search for traits that make species good invaders, or ecosystems susceptible to invasion, are yielding idiosyncratic results. To move forward, we advocate more synthetic approach incorporates range different types information about and communities habitats they invading. (ii) Given growing evidence adaptive...
Anthropogenic biodiversity decline threatens the functioning of ecosystems and many benefits they provide to humanity1. As well as causing species losses in directly affected locations, human influence might also reduce relatively unmodified vegetation if far-reaching anthropogenic effects trigger local extinctions hinder recolonization. Here we show that plant diversity is globally negatively related level activity surrounding region. Impoverishment natural was evident only when considered...
Abstract Sprouting vigour is determined by the plant amount of reserves and intrinsic growth rate plants. While first factor has been well studied, second far less understood. Although a higher would imply sprouting vigour, fast‐growing species may have below‐ground reserves, thus, lower potential. The relative importance both opposite effects was little explored in literature. To analyse influence on one season after fire we measured height old (pre‐fire) new (post‐fire) tissue 194...
ABSTRACT Aims Land use modifies natural forest herbivore assemblages by cattle introduction and structural alteration that impact invertebrate diversity. This land herbivory combined effect is particularly relevant for woody plant juveniles, which are key stages regeneration. We aimed to understand how on juvenile plants affected use. In this study, we analyzed vertebrate patterns seedlings saplings change between uses in winter summer seasons. Location Southernmost Gran Chaco region,...
Abstract The network of minor veins angiosperm leaves may include loops (reticulation). Variation in architecture has been hypothesized to have hydraulic and also structural defensive functions. We measured venation trait space eight dimensions for 136 biomass‐dominant tree species along a 3,300 m elevation gradient southeastern Peru. then examined the relative importance multiple ecological evolutionary predictors reticulation. reticulation was constrained three axes. These axes described...
Abstract Aim Plant species continue to be moved outside of their native range by human activities. Here, we aim determine whether, once introduced, plants assimilate into communities or whether they aggregate, thus forming mosaics native‐ and alien‐rich communities. Alien might aggregate in non‐native owing shared habitat preferences, such as tendency establish high‐biomass, species‐poor areas. Location Twenty‐two herbaceous grasslands 14 countries, mainly the temperate zone. Time period...
Abstract Questions: The existence of reservoirs from which dominant plants recruit after disturbances is a key factor in ecosystem resilience. With this mind, we ask the following qestion: where do woody species regenerate semiarid Neotropical Chaco forest? Is land use affecting floristic composition biodiversity reservoirs? Are soil and litter seed banks juvenile bank potential sources resilience these forests face different land‐use regimes? Location: Chancaní, Northwestern Córdoba,...

Abstract Resilience—the capacity of an ecosystem to recover from disturbance—is a popular concept but quantitative empirical studies are still uncommon. This lack evidence is especially true for semi‐arid ecosystems in the face combined and often confounding impacts land use climate changes. We designed methodology disentangle vegetation responses land‐use exclusion weather variability, piloted it at southern extreme Gran Chaco forest, most extensive seasonally dry forest South America....
Background and Aims The influence of leaf mechanical properties on local ecosystem processes, such as trophic transfer, decomposition nutrient cycling, has resulted in a growing interest including resistance large-scale databases plant functional traits. ‘Specific work to shear’ ‘force tear’ are two commonly used describe (toughness or strength) leaves. Two methodologies have been widely measure them across large datasets. This study aimed assess correlations standardization between the...
Bidens pilosa L. is a summer annual that shows particular phenological pattern in the Córdoba mountains, Argentina. Some individuals start flowering 1 month after germination (early type), but most of population starts 4 months (normal type). The aims this study were to (1) analyse whether differences phenology affect seed mass and production, (2) assess possible traits two parental types would germinability, rate, seedling growth offspring under laboratory conditions. showed numbers seeds...
