The native biodiversity of oceanic islands is threatened by human-driven disturbance and the growing number species introductions which often interfere with natural ecological processes. Here, we aim to evaluate effect anthropogenic on plant-pollinator interactions in forest communities an island (Terceira, Azores, Portugal). We found that predominated preserved sites compared disturbed ones extant were mostly dominated generalist species. Dipterans, particularly hoverflies, emerged as primary flower visitors, while introduced hymenopterans (Apis mellifera Bombus terrestris) beetles locally important, respectively, sites. Human-driven seems be responsible for observed differences abundance composition between drive changes specific network metrics (namely nestedness, interaction strength asymmetry, specialization), one study areas. Our findings also suggest provide opportunities can facilitate establishment through their broad networks.

Abstract Understanding what determines community assembly and disassembly in a changing environment is core challenge for ecology. Recently family of structural stability approaches that determine the range intrinsic growth rates compatible with system feasibility have been gaining popularity as measure how likely able to persist fluctuating conditions. This offers theoretical basis understanding predicting complex multi-species communities from only interaction network structures. However, here I show high sensitivity calculations domain, coupled empirical uncertainties inherent estimated interactions, are preclude approach’s reliable application settings. Across four reanalyses previous demonstrations approach, more parsimonious explanations based on species connectance provide better patterns or dynamic stability. Calculation metrics therefore appears lose, rather than synthesise, information embedded matrices. success simpler measures good news purposes prediction emphasises value multiple-competing hypotheses validation tests demonstrate value-added associated new approaches.

Natural ecosystems are characterized by a specialization pattern where few species common while many others rare. In ecological networks involving biotic interactions, operates as continuum at individual, species, and community levels. Theory predicts that evolutionary factors can primarily explain specialization. However, we still do not understand how scales from individuals to the community. This question has been addressed emerging research program on macroecology of which focuses macroecological theory investigate interaction patterns along environmental geographical gradients. Based traits interacting study traditionally focused characterization whole or particular independent units. Instead, perspective requires shift towards assessing network variation across gradients also accounting for different temporal (hours, days, years) spatial (local, regional, global) levels organization (individual‐based, species‐based, meta‐networks).

ABSTRACT Plant–plant interactions are major determinants of the dynamics terrestrial ecosystems. There is a long tradition in study these interactions, their mechanisms and consequences using experimental, observational theoretical approaches. Empirical studies overwhelmingly focus at level species pairs or small sets species. Although empirical data on community scarce, such have gained pace last decade. Studying plant–plant requires knowledge which interact with others, so an ecological networks approach must be incorporated into basic toolbox plant ecology. The concept recruitment (RNs) provides integrative framework new insights for many topics field RNs synthesise set canopy–recruit local assemblage. Canopy–recruit describe (“canopy”) allow other vicinity how. Here we critically review concepts network theory as they apply to RNs. We use RecruitNet, recently published worldwide RN patterns emerging interaction, species, levels, relate them different abiotic gradients. Our results show that can sampled high accuracy. included RecruitNet very mean completeness (95%), indicating undetected few occur infrequently. Across 351,064 analysed, effect interaction was neutral average 69% per community, but remaining were positive (i.e. facilitative) five times more often than negative competitive), had twice strength ones.
