Temporal displacement of flowering peaks, strong pollinator specificity, and high flower constancy in the shared pollinator all contributed to limiting hybridization in this site, which suggests different phenological windows and pollination assemblages may allow greater frequency of the hybrid.

The first estimates of hybridisation and polyploidy frequency in the Mediterranean region are provided and it is found that <6% of Mediterranean plants were hybrids, although a higher frequency was estimated for the Iberian Peninsula, and the ecological factors driving emergence and establishment of new entities are still poorly studied.

Five Mediterranean autumn-flowering geophytes that usually co-exist in fire-prone habitats were selected, revealing different patterns of seed germination and suggesting the absence of a permanent soil seed bank in the life cycle of these geophyes.
Pollination activity affects selection on floral longevity in the autumnal-flowering plant, Narcissus serotinus L.

It is suggested that extended flower longevity is selected because it assures pollination suc- cess under scarce insect visits and is a selective advantage under unpredictable or scarce pollination activity.

An approach to the conservation status of Mediterranean temporary ponds located at Campo Militar de Santa Margarida (Ribatejo, Portugal) is presented. Two conservation indexes were applied to this…
Multiple hybridization events, polyploidy and low postmating isolation entangle the evolution of neotropical species of Epidendrum (Orchidaceae)

The recurrent process of hybridization has compromised the genetic integrity of the parental species and the prediction of suitable conditions for the future occurrence of these hybrid zones highlights the importance of conserving these geographic areas as sources of novel taxonomic entities.
Rock outcrop orchids reveal the genetic connectivity and diversity of inselbergs of northeastern Brazil

Both orchids Epidendrum cinnabarinum and E. secundum showed similar patterns of genetic diversity and structure, highlighting the importance of seed-restricted gene flow and genetic drift as drivers of plant diversification in terrestrial islands such as inselbergs.
