LINKING BEES AND FLOWERS: HOW DO FLORAL COMMUNITIES STRUCTURE POLLINATOR COMMUNITIES?
It is concluded that floral resources act in specific and previously unexplored ways to modulate the diversity of the local geographic species pool, with specific disturbance factors, superimposed upon these patterns, mainly affecting the dominant species.
Role of nesting resources in organising diverse bee communities in a Mediterranean landscape
Abstract. 1. The habitat components determining the structure of bee communities are well known when considering foraging resources; however, there is little data with respect to the role of nesting…
Response of plant-pollinator communities to fire: changes in diversity, abundance and floral reward structure
A novel and highly integrated approach is presented, which quantifies, in parallel, the response to fire of pollinator communities, floral communities and floral reward structure.
Reproductive traits of Pinus halepensis in the light of fire – a critical review
It is suggested that a number of generations is sufficient for the selection and radiation of fire adaptive traits in P. halepensis, a relatively short living tree with almost no recruitment under forest canopy.

A new proposed conceptual framework with a modular approach based on pollen deposition, visit frequency, and contribution to seed set relative to the plant's maximum female reproductive potential is proposed, to optimize the balance between idealised theoretical concepts and practical operational methods.

It is indicated that honeybees can cope with naturally occurring concentrations of nicotine, without notable mortality, even when consumed in large quantities for more than 3 weeks.

Post-fire regeneration and invasion are strategies, which seem to complement each other in Pinus halepensis, suggesting a fast selection for serotiny by fire.
Spatiotemporal dynamics of recruitment in Aleppo pine (Pinus halepensis Miller)
Most studies of Aleppo pine recruitment have focused on the seedling and sapling stages and on post-fire regeneration; this work calls for greater attention to the seed stage and to more extensive sampling of all recruitment stages in both space and time.
Nectar resource diversity organises flower‐visitor community structure
It is concluded that relying solely upon measurements ofmean nectar volume and mean nectar concentration overlooks a key characteristic of community‐level reward structure, nectar resource diversity, so that previous studies may have failed to identify an important determinant of flower‐visitor community structure.
Pollination of Oncocyclus irises (Iris: Iridaceae) by night-sheltering male bees.
It is concluded that fertilization of Oncocyclus irises is totally dependent on pollination by night-sheltering solitary male bees.
