Reproductive ecology of Rhododendron ponticum (Ericaceae) in relict Mediterranean populations
- J. A. Mejías, J. Arroyo, F. Ojeda
- Environmental Science
- 1 November 2002
It is proposed that the Rhododendron ponticum species shows a variable balance between sexual reproduction and vegetative multiplication depending on environmental conditions, and is discussed as a mechanism allowing persistence during geological climatic oscillations.
Rangewide phylogeography of a bird‐dispersed Eurasian shrub: contrasting Mediterranean and temperate glacial refugia

Populations from the southern parts of the glacial refugia have contributed little to the postglacial recolonization of Europe, but their long‐term historical continuity has allowed them to maintain a unique store of genetic variation.
Reconstructing the demise of Tethyan plants: climate‐driven range dynamics of Laurus since the Pliocene
- F. Rodríguez‐Sánchez, J. Arroyo

- 1 November 2008
Aim Climate changes are thought to be responsible for the retreat and eventual extinction of subtropical lauroid species that covered much of Europe and North Africa during the Palaeogene and early…

Nectar was significantly depleted by insects in some exotic populations of Rhododendron ponticum, suggesting that this invasive species is providing a floral resource for native Insects in some parts of Ireland.
Beyond species loss: The extinction of ecological interactions in a changing world
- A. Valiente‐Banuet, M. Aizen, R. Zamora
- Environmental Science
- 1 March 2015
A novel model proposes a novel approach that relates the diversity of both species and interactions along a gradient of environmental deterioration and explores how the rate of loss of ecological functions, and consequently of ecosystem services, can be accelerated or restrained depending on how the rates of species loss covaries with the rateof interactions loss.
Variations in habitat, season, flower traits and pollinators in dimorphic Narcissus tazetta L. (Amaryllidaceae) in Israel.
The findings are consistent with the hypothesis of lower efficiency of pollination of S flowers by short-tongued insects, resulting in the exclusion of this morph from the hills, and variation in a set of continuous flower traits related to pollination biology was examined.
Soil seed bank and floristic diversity in a forest-grassland mosaic in southern Spain

- 1 October 2003
The role of soil seed banks in the vegetation dynamics and in the complete plant biodiversity of the mosaic landscape studied is discussed.
Late Neogene history of the laurel tree (Laurus L., Lauraceae) based on phylogeographical analyses of Mediterranean and Macaronesian populations
- F. Rodríguez‐Sánchez, B. Guzmán, A. Valido, P. Vargas, J. Arroyo
- Biology, Environmental Science
- 1 July 2009
The historical range shifts of Laurus, a paradigmatic tree of the Tethyan flora that has covered southern Eurasia since the Oligo‐Miocene, are inferred by means of phylogenetic and phylogeographical analyses.
