Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system thought to influence aspects plant-herbivore biology, from ecological stability plant defense evolution. Our understanding what influences variability, however, limited by sparse data. We collected standardized surveys herbivory for 503 species at 790 sites across 116° latitude. With these data, we show that within-population increases...
Abstract Aim Spatial variation in predation can shape geographic patterns ecology and evolution, but testing how varies across ecosystems is challenging as differing species compositions defensive adaptations mask underlying patterns. Recently, biogeography has borrowed a tool from ecology: clay prey models. But models have not been adequately tested for comparisons, well‐known problem –that only appeal to subset of potential predators– could bias detected whenever the relative importance...
Plant-soil feedbacks (PSFs) have been shown to strongly affect plant performance under controlled conditions, and PSFs are thought far reaching consequences for population dynamics the structuring of communities. However, thus relationship between PSF species abundance in field is not consistent. Here, we synthesize experiments from tropical forests semiarid grasslands, test a positive estimated bioassays. We meta-analyzed results 22 found an overall correlation (0.12 ≤ r¯ 0.32) across...
Trait differences between native and non‐native populations may explain the greater abundance impact of some organisms in their ranges than ranges. Here, we conducted reciprocal common gardens southwestern Turkey (home) central Argentina (away) to explore hypothesis that success invasive ruderal Centaurea solstitialis is partially explained by home away populations. Unusual among gardens, our experimental design included seed additions explicitly evaluate population level responses, as well...
Abstract Many invasion hypotheses propose biotic interactions as the main mechanism to explain non‐native species' success. Despite evidence that strength of varies with abiotic context, it remains unclear whether importance different mechanisms proposed predictably context and this variation is consistent across growth forms. We reviewed studies at a global scale evaluate evapotranspiration, latitude, precipitation temperature influence disturbance, enemy release, facilitation, novel...
There are many hypotheses aiming to explain invasion success, but evaluating individual in isolation may hinder our ability understand why some species invade and others fail. Here we evaluate the interaction between propagule pressure, seed predation missed mutualism success of pine, Pinusponderosa . We evaluated independent interactive effects pressure at increasing distances from a pine plantation. Additionally, because pines obligate mutualists with ectomycorrhizal fungi (EMF) invasions...

Making predictions about when and where a given mechanism of invasion will be weak or strong is crucial for the effective management non‐native species. Despite importance disturbance on invasion, our understanding how variation in abiotic and/or biotic conditions may modify disturbance‐invasion relationship scarce. Here, we aimed to evaluate (soil type) (tree shrub cover) contexts affect disturbance–invasion disturbed nearby non‐disturbed communities semi‐arid open forest central Argentina...
Amid global environmental crises threatening the survival of many species, including our own, a diverse group scientists from 15 countries and members 16 professional academic societies, concerned with current crisis met in February 2024 to address urgent need reflect on, identify, core values responsibilities as individual professionals societies. We invited fellow join this conversation we share here result discussion, which was informed by: i) experiences; ii) scoping review mission...
Abstract Urbanization can profoundly disrupt local ecology. But while urban areas now stretch across latitudes, little is known about urbanization’s effects on macroecological patterns. We used standardized experiments to test whether urbanization disrupts latitudinal gradients in seed predation, a pattern that shapes community assembly and diversity. Using >56,000 seeds, we compared predation urbanized natural 14,000 km of latitude, spanning the Americas. Predation increased 5-fold from...
