1 Once neglected, the role of facilitative interactions in plant communities has received considerable attention last two decades, and is now widely recognized. It timely to consider progress made by research this field. 2 We review development facilitation research, focusing on history field, relationship between plant–plant environmental severity gradients, attempts integrate into mainstream ecological theory. then future directions for research. 3 With respect our fundamental...
We propose an index to measure the relative interaction intensity in plants (RII) with strong mathematical and statistical properties which overcome problems shown by other frequently used indices. RII has defined limits [−1, +1]; is symmetrical around zero, identical absolute values for competition facilitation; linear; does not have discontinuities its range. It therefore safe use operations. distribution approximately normal, means equal true population a sampling variance that can be...
Summary Environmental gradients may influence a plant's physiological status and morphology, which in turn affect plant–plant interactions. However, little is known about the relationship between environmental variation, morphological variability of plants variation balance competition facilitation. Mountain ranges dry environments have opposing altitudinal temperature aridity, limit plant growth at high low elevations. This makes them particularly suitable for exploring relationships...
Summary The structure and composition of plant communities are influenced by positive negative interactions between plants, the balance which may change in intensity sign through time space, depending on availability resources life history. Over a 2‐year period we analysed different stages perennial grass, Stipa tenacissima , shrub, Cistus clusii dominant species semi‐arid community south‐east Spain. shrubs acted as nurses for juvenile improving their water status, nutrient content, carbon...
Abstract. Competition and facilitation may occur simultaneously in plant communities, the prevalence of either process depends on abiotic conditions. Here we attempt a community‐wide approach analysis interactions, exploring whether semi‐arid environment positive or negative interactions predominate there are differences among co‐occurring shrub species. Most shrubs our plot exerted significant effects their understorey ranging from to positive. We found clear case interference another where...

Aims: The stress-gradient hypothesis (SGH) predicts how plant interactions change along environmental stress gradients. We tested the SGH in an aridity gradient, where support for and specific shape of its response curve is controversial. Location: Almería, Cáceres Coimbra, three sites Iberian Peninsula that encompass most arid wet habitats distribution range a nurse shrub species –Retama sphaerocarpa L. (Boiss) – Europe. Methods: analysed effect Retama on understorey community measured...
Summary The least‐cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has cope with dual challenge imposed by drought nutrient‐poor soils. We addressed how variation leaf per area (N ) modulates oxygen isotopic composition (δ 18 O, δ 13 C), as proxies stomatal conductance water‐use efficiency, across 34 Sahelian woody species. Dryland species exhibited diverging O C values,...
Abstract Question: How does the interaction between two dominant shrub species in a coastal sand dune community change during their life history? Does this influence population dynamics? Location: A semiarid system southeast Spain. Methods: For 3 years we monitored physiological status, growth and reproductive effort of Juniperus phoenicea Pistacia lentiscus , species, growing either alone or close spatial association. We also recorded adult mortality patterns characterized seedling...
Facilitation by nurse plants plays an important role in determining community composition severe environments. Although the unidirectional effect of nurses on beneficiary species has received considerable research interest, nurse‐mediated interactions among (so‐called indirect interactions) are less known. Consequently, plant systems is generally considered as a simple consequence facilitative even though may significantly contribute to assembly and modulate direct effects community. In...
Summary Plant–plant facilitation is an important driver of plant diversity, which in turn maintains ecosystem multifunctionality and can buffer some negative effects climate change. Facilitation classically attributed to the amelioration environmental extremes resource availability. Integrating below‐ground biota into positive interactions framework should provide a more realistic understanding this process, enabling us gain insights dynamics below–above‐ground communities. We tested effect...
Summary The nature of the relationship between water limitation and facilitation has been one most contentious debates surrounding stress‐gradient hypothesis ( SGH ), which states that plant‐plant interactions shift from competition to with increasing environmental stress. We take a closer look at potential role soil moisture in mediating interaction outcomes by assessing effects climate texture on plant modulation moisture. Using an empirically‐parameterized model, we simulated dynamics...
Competition is a key process that determines plant community structure and dynamics, often mediated by nutrients water availability. However, the role of soil microorganisms on competition, links between above- belowground processes, are not well understood. Here we show effects interspecific competition performance feedbacks plants bacterial communities. Each species selects singular in its rhizosphere with specific composition, abundance activity. When two interact, resulting matches most...
Cacao (Theobroma cacao L.) has traditionally been considered a crop that requires shade, and consequently it is implemented under agroforestry systems (AFs) in order to regulate the level of incident solar radiation. However, optimal shade levels for this tree may vary depending on climate conditions where grown. Here we analyzed physiological performance three different AFs Colombian Amazon differed radiation patterns: high (HPAR), medium (MPAR), or low (LPAR) mean daily The was...
Summary Facilitation is known as the positive effect of one species (benefactor) on associated neighbouring (beneficiaries). Although beneficial part this interaction has received considerable research interest, there a gap knowledge bidirectional nature these interactions; in particular, physiological and fitness consequences for both beneficiaries benefactors. Alpine cushion plants are generally strong benefactors, increasing richness abundance global scale, provide suitable system to...
