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

Extreme variation in floral characters and its consequences for pollinator attraction among populations of an Andean cactus.
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

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

A simple floral fragrance and unusual osmophore structure in Cyclopogon elatus (Orchidaceae).
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
