Concepción Ornosa

TL;DR: This study analysed the temporal dynamics of a plant – flower visitor network in two Mediterranean alpine communities during one complete flowering season and identified the effect of within-season temporal variation of plant and flower visitor activity on the network structural conformation.

TL;DR: Specialization of the personate flower of Antirrhinum is interpreted for bees with both large bodies and high visitation indices, suggesting that these bee guilds are effective pollinators of the three self-incompatible Antirkhinum species.

TL;DR: It is suggested that the two main melanin forms, at variable amounts and/or vibrational states, are sufficient in giving almost the whole color range of bumblebee pubescence, allowing these insects to use a single precursor instead of synthesizing a variety of chemically different pigments.

TL;DR: It is shown that floral variation can be driven by shifts between pollinators that have been traditionally included in a single functional group, and the consequences of such transitions for plant species differentiation during rapid radiations are discussed.

TL;DR: It is found that melon flowers are visited by 31 species of bees spanning four families, though only four were both dominant and constant, and Observations on the frequency of pollen and nectar foraging and on flower visit duration suggested L. malachurum as the potential key pollinator.
