Comparing the power of phylogenetic, trait and network structure information to predict plant–frugivore interactions

Oikos, EarlyView.
Due to the constraints of limited effort and sampling error, observed species interaction networks are an imperfect representation of the ‘true' underlying community. Link prediction methods allow us to construct a potentially more complete representation of a given empirical network by guiding targeted sampling of predicted links, as well as offer ...

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

Oikos, EarlyView.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

Recurrent drought amplifies drought impacts and increases seasonal synchrony in mountain grassland communities

Oikos, EarlyView.
Climate change increases the recurrence of drought events with strong repercussions on grassland ecosystems. While the effects of single drought events on ecosystem structure and functioning are well understood, it is largely unknown whether and how recurrent drought events modify ecosystem responses to subsequent drought.

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

Oikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Different from the start: key dimensions of seedling traits of central European temperate grassland species

Oikos, EarlyView.
Plant traits and their tradeoffs are major determinants of plant functions. Although trait‐based frameworks should apply to plant functioning at any life stage, they have been primarily established for adult plants. Therefore, we lack comprehensive trait‐based studies of seedlings across multiple species to prove which key dimensions of trait variation

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits

Oikos, EarlyView.
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

On the evolution of floral traits : Variation in complex floral phenotypes across pollination environments

Pollinators play a central role in shaping the astounding diversity of angiosperm flowers. Flowers are complex, multidimensional, genetically and functionally integrated phenotypes, rendering it a challenge to quantify and interpret observed trait variation.

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

Oikos, EarlyView.
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...
