Functional traits are expected to modulate plant competitive dynamics. However, how and their plasticity in response contrasting environments connect with the mechanisms determining species coexistence remains poorly understood. Here, we couple field experiments under two climatic conditions a population model describing dynamics between 10 annual order evaluate 19 functional traits, covering physiological, morphological reproductive characteristics, associated species' niche fitness...
Abstract Global climate change is expected to further raise the frequency and severity of extreme events, such as droughts. The effects droughts on trees are difficult disentangle given inherent complexity drought events (frequency, severity, duration, timing during growing season). Besides, might be modulated by trees’ phenotypic variability, which is, in turn, affected long‐term local selective pressures management legacies. Here we investigated magnitude temporal changes tree‐level...
Understanding seedling performance across resource gradients is crucial for defining the regeneration niche of plant species under current environmental conditions and predicting potential changes a global change scenario. A 2‐year field experiment was conducted to determine how survival growth two evergreen deciduous Quercus vary along light soil properties in Mediterranean forests with contrasting soils climatic conditions. Half seedlings were subjected an irrigation treatment during first...
Abstract Ongoing changes in global climate are altering ecological conditions for many species. The consequences of such typically most evident at the edge a species’ geographical distribution, where differences growth or population dynamics may result range expansions contractions. Understanding responses to different climatic drivers along wide latitudinal and altitudinal gradients is necessary order gain better understanding plant ongoing increases temperature drought severity. We...
Changes in rainfall availability will alter soil-nutrient under a climate-change scenario. However, studies have usually analyzed the effect of either drier or wetter soil conditions, despite fact that both possibilities coexist many climatic regions world. Furthermore, its may vary across different habitats ecosystem. We experimentally investigated three contrasting scenarios on carbon (C), nitrogen (N), and phosphorus (P) fractions microbial compartments among characteristic...
Abstract Question: How does habitat degradation affect recruitment limitation and its components (seed versus establishment limitation) of woody plant communities in a Mediterranean landscape? Location: 1600‐1900 m a.s.l. the Sierra Nevada National Park, southern Spain. The landscape is mosaic composed native forest two degraded units: reforestation stands shrubland. Methods: We evaluated fruit production, seed rain, seedling emergence survival consecutive years with contrasting rainfall...
Abstract Very little is known about how variation in environmental conditions alters the strength and structure of competitive networks what are consequences this for species coexistence. We performed a competition experiment with 10 annual plant to parameterise population model describing species’ dynamics according their vital rates pairwise coefficients. Seeds from all were sown under two different climatic scenarios: (1) right before first major storm growing season (2) after an imposed...
Abstract Climatic dryness imposes limitations on vascular plant growth by reducing stomatal conductance, thereby decreasing CO 2 uptake and transpiration. Given that transpiration‐driven water flow is required for nutrient uptake, climatic stress‐induced deficit could be a key mechanism decreased performance under prolonged drought. We propose the existence of an “isohydric trap,” dryness‐induced detrimental feedback leading to stoichiometry imbalance in strict isohydric species. tested this...
Ongoing changes in global climate are having a significant impact on the distribution of plant species, with effects particularly evident at range limits. We assessed capacity Pinus sylvestris L. populations northernmost and southernmost limits to cope projected climate. investigated responses including seed germination early seedling growth survival, using seeds from (Kevo, Finland) (Granada, Spain) populations. Seeds were grown under current conditions each area temperatures increased by 5...
Abstract Ecologists have long argued that higher functioning in diverse communities arises from the niche differences stabilizing species coexistence and fitness driving competitive dominance. However, rigorous tests are lacking. We couple field-parameterized models of competition between 10 annual plant with a biodiversity-functioning experiment under two contrasting environmental conditions, to study how determinants link biodiversity effects (selection complementarity). find...
Seed dispersal by Red fox ( Vulpes vulpes ), Stone marten Martes foina and Wild boar Sus scrofa ) was analyzed in an extensively degraded mosaic landscape Sierra Nevada (SE Spain). The main objective to determine whether seed mammals related habitat degradation within a of adjacent patches mixed with native forest thereby the potential role as dispersers units. For three consecutive years, mammal feces were collected fruit production period, extracting all seeds woody species found therein...
Ongoing changes in global climate are altering ecological conditions for many species. The consequences of such typically most evident at the edge geographical distribution a species, where range expansions or contractions may occur. Current demographical status limits can help us to predict population trends and their implications future Thus, understanding comparability patterns occurring along both altitudinal latitudinal gradients would be highly informative. In this study, we analyse...
Sustainability and functioning of silvopastoral ecosystems are being threatened by the forecasted warmer drier environments in Mediterranean region. Scattered trees these could potentially mitigate impact climate change on herbaceous plant community but this issue has not yet tested experimentally. We carried out a field manipulative experiment increased temperature (+2-3 °C) using Open Top Chambers rainfall reduction (30%) through rain-exclusion shelters to evaluate how net primary...
There is growing interest in the consumption of halophytes due to their excellent nutritional profile and antioxidant properties, cultivation offers viable alternatives face irreversible global salinization soils. Nevertheless, abiotic factors strongly influence phytochemical composition, little known about how conditions can produce plants with best functional properties. Crithmum maritimum an edible halophyte properties considerable potential for sustainable agriculture marginal...
Objective: This study aimed to identify the incidence of adolescent pregnancies, types deliveries, hospitalization categories, and obstetric diagnoses in a Brazilian university hospital between January 2019 August 2021. Methods: A retrospective was conducted, analyzing 188 electronic medical records adolescents aged 10 19 years. The variables collected included age, number risk level hospitalization, length stay, maternal fetal complications, diagnoses, family planning, gestational age at...
This study examines the consequences of adjacent elements for a given patch, through their effects on zoochorous dispersion by frugivorous birds. The case consists pine plantations (the focal patch) to other patches native vegetation (mixed forest and shrublands), and/or plantations. Our hypothesis is that input woody species propagules generated birds within strongly depends nature surrounding vegetation. To test this hypothesis, we studied frugivorous‐bird abundance, seed dispersion,...
Climate change is a fundamental process affecting terrestrial ecosystems. However, there relatively little knowledge about its impacts on soil communities, with large degree of uncertainty regarding their resistance to predicted alterations in temperature and, particularly, precipitation. Moreover, most studies exploring the response biota rainfall reduction have focused mesic environments and microbes, which limit our ability find general patterns across ecosystems organisms. In this study,...
