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.

Oikos, EarlyView.Climatic conditions alter the phenology of species, which may threaten the synchrony of biotic interactions. However, how phenological synchrony across entire communities of plants and their pollinators responds to varying environmental conditions remains poorly understood.

Reproductive aspects and flower visitors of Duguetia marcgraviana Mart. (Annonaceae) in the southwestern region of Mato Grosso [PDF]
Biotemas, 2010 The biology and flower visitors of Duguetia marcgraviana were studied in a forest fragment of the Municipality of Tangará da Serra – MT. The flowering phenology was monitored in eight adult plants and the numbers of flower buds and open flowers were ...

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 ...

Pollinating insect responses to grazing intensity, grassland characteristics and landscape complexity [PDF]
, 2007 Pollinators uphold important ecological functions and their economic and ecological importance is considerable. In the present thesis the relationship between management practices and the behaviour, diversity and composition of four flower visitor groups:

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 ...
