Epiparasitic plants specialized on arbuscular mycorrhizal fungi
Over 400 non-photosynthetic species from 10 families of vascular plants obtain their carbon from fungi and are thus defined as myco-heterotrophs. Many of these plants are epiparasitic on green plants… Expand
Emerging phylogeographical patterns of plants and terrestrial vertebrates from Patagonia
Phylogeographical inferences, applied in a comparative framework across multiple species at a regional scale, provide the means for detecting regional and landscape-level patterns of biodiversity,… Expand
Multiple periglacial refugia in the Patagonian steppe and post-glacial colonization of the Andes: the phylogeography of Calceolaria polyrhiza
Aim We perform a phylogeographical study of an endemic Patagonian herbaceous plant to assess whether geographical patterns of genetic variation correspond to in situ Pleistocene survival or to… Expand

BACKGROUND AND AIMS A South American cactus species, Echinopsis ancistrophora (Cactaceae), with dramatic among-population variation in floral traits is presented. METHODS Eleven populations of E.… Expand
Functional morphology and wasp pollination of two South American asclepiads (Asclepiadoideae-Apocynaceae).
UNLABELLED BACKGROUND AND AIMS The extreme complexity of asclepiad flowers (Asclepiadoideae-Apocynaceae) has generated particular interest in the pollination biology of this group of plants… Expand
Specialized use of pollen vectors by Caesalpinia gilliesii, a legume species with brush-type flowers
The pollination of Caesalpinia gilliesii (Fabaceae), a legume species with long, brush-type flowers, was studied in wild populations in Argentina. A total of 341 hawkmoths (Sphingidae), belonging to… Expand
Oil-Collecting structures in Tapinotaspidini: their diversity, function and probable origin (Hymenoptera: Apidae)
Evidence of rodent pollination inCajophora coronata (Loasaceae)
Vegetative and floral features ofCajophora coronata (Loasaceae) suggest adaptations to pollination by rodents: (1) mammal guard represented by a covering of stinging hairs; (2) geoflory; (3) white… Expand

We studied gland morphology, anatomy and the chemical composition of the floral fragrance in the sweat bee-pollinated orchid Cyclopogon elatus. This is apparently the first such analysis for any… Expand
RESTRICTION OF POLLINATOR ASSEMBLAGE THROUGH FLOWER LENGTH AND WIDTH IN THREE LONG-TONGUED HAWKMOTH–POLLINATED SPECIES OF MANDEVILLA (APOCYNACEAE, APOCYNOIDEAE)1
Abstract Apocynaceae have a precise pollination mechanism. However, broad pollinator assemblages, including several insect orders, have often been recorded. We test how the corolla tube length and… Expand
