Plants require water and nutrients for survival, although the effects of their availabilities on plant fitness differ amongst species. Genome size variation, within across species, is suspected to influence nutrient requirements, but little known about how variations in these resources concurrently affect based genome size. We examined variation between autopolyploid cytotypes influences morphological physiological traits, whether cytotype-specific trait responses and/or availability. Diploid autotetraploid Solidago gigantea (Giant Goldenrod) were grown a greenhouse under four soil water:N+P treatments (L:L, L:H, H:L, H:H), stomata characteristics (size, density), growth (above- belowground biomass, R/S), (Anet , E, WUE) measured. Resource cytotype identity influenced some independent each other. high-water larger, plants low-water or high-nutrient had higher WUE lower Anet E rates decreased as aged.

Microbial interactions are key to maintaining soil biodiversity. However, whether negative or positive associations govern the microbial system at a global scale remains virtually unknown, limiting our understanding of how microbes interact support biodiversity and functions.

Pesticide application is essential for stabilizing agricultural production. However, the effects of increasing pesticide diversity on soil microbial functions remain unclear, particularly under varying nitrogen (N) fertilizer management practices. In this study, we investigated stochasticity microbes and multitrophic networks through amplicon sequencing, assessed community related to carbon (C), N, phosphorus (P), sulfur (S) cycling, characterized dominant bacterial life history strategies via metagenomics along a gradient two N addition levels. Our findings show that higher enriches abundance specialists opportunists capable degrading or resisting pesticides, reducing proportion generalists in absence addition. These shifts can complicate networks. Under increased diversity, selective pressure may drive bacteria streamline their average genome size conserve energy while enhancing C, P, S metabolic capacities, thus accelerating nutrient loss. comparison, was found reduce niche differentiation at mitigating impacts network complexity functional traits associated with ultimately alleviating results reveal contrasting different input scenarios emphasize strategic mitigate ecological use systems.

Network ecology is an emerging field that allows researchers to conceptualize and analyse ecological networks their dynamics. Here, we focus on the dynamics of in response environmental changes. Specifically, formalize how network topologies constrain systems into a unifying framework refer as 'ecological framework'. This stresses interplay between species interaction spatial layout habitat patches key identifying which properties (number weights nodes links) trade-offs among them are needed maintain interactions dynamic landscapes. We conclude be functional, should scaled according dispersal abilities landscape heterogeneity. Determining such effective change through space time can help reveal complex changing world.

Species interactions are key drivers of biodiversity and ecosystem stability. Current theoretical frameworks for understanding the role make many assumptions which unfortunately, do not always hold in natural, diverse communities. This mismatch extends to annual plants, a common model system studying coexistence, where typically averaged across environmental conditions transitive competitive hierarchies assumed dominate. We quantify interaction networks community wildflowers Western Australia natural shade gradient at local scales. Whilst competition dominated, intraspecific interspecific facilitation were widespread all categories. Interaction strengths directions varied substantially despite close spatial proximity similar levels species richness, with most interacting different ways under conditions.

Abstract Biotic interactions are widely recognised as the backbone of ecological communities, but how best to study them is a subject intense debate, especially at macro‐ecological scales. While some researchers claim that biotic need be observed directly, others use proxies and statistical approaches infer them.

Modern coexistence theory (MCT) holds the potential to study ability of species avoid extinction (i.e. persist) across community types but is rarely applied beyond pairs competing species. Here, we show that this limitation can be overcome by mapping according their niche ( ) and fitness differences ). This application provides three main benefits processes multispecies persistence trophic levels. First, introduces a novel categorization communities high‐level at play: frequency dependence (negative or positive), occurrence positive interactions (facilitation mutualism) whether possible without presence other because interactions, such as herbivory predation. Therefore, seen toolbox describe how depends on interactions.
