MORFOLOGIA Y ESTRATEGIAS REPRODUCTIVAS DEL GAMETOFITO DE POLYPODIUM LEPIDOTRICHUM (FEE) MAXON (POLYPODIACEAE)
- Endothermy by flowers of Rhizanthes lowii (Rafflesiaceae). Patiño, Sandra; Grace, John; Bänziger, Hans // Oecologia;Aug2000, Vol. 124 Issue 2, p149
Rhizanthes lowii (Beccari) Harms (Rafflesia- ceae) is a parasitic plant that grows in the understory of the rainforest in South-East Asia. This plant does not have leaves, stems, or photosynthetic tissue and is characterised by the emission of a strong odour that attracts the natural...
- Comparative pollinator limitation of two non-native shrubs: do mutualisms influence invasions? Parker, Ingrid M.; Haubensak, Karen A. // Oecologia;Jan2002, Vol. 130 Issue 2, p250
While interactions between invaders and resident species have received a great deal of attention recently, the role of mutualists in facilitating or constraining invasions is rarely considered. We investigated the reproductive ecology of two closely related, woody legumes, Cytisus scoparius...
- self-pollination. // Hutchinson Dictionary of Scientific Biography;2005, p1
Pollination of a plant by itself, whether intra- or interfloral.
- pollinator:. Gough, Robert E. // Glossary of Vital Terms for the Home Gardener;1993, p72
A definition of the term "pollinator" is presented. It refers to a causative agent of pollination, such as bees and wind.

- Experimental investigation of the effect of spatial aggregation on reproductive success in a rewardless orchid. Internicola, Antonina I.; Juillet, Nicolas; Smithson, Ann; Gigord, Luc D. B. // Oecologia;Nov2006, Vol. 150 Issue 3, p435
Plant reproductive success within a patch may depend on plant aggregation through pollinator attraction. For rewardless plants that lack rewards for pollinators, reproductive success may rely strongly on the learning abilities of pollinators. These abilities depend on relative co-flowering...
- Reproductive biology of the melon cactus,Melocactus curvispinus(Cactaceae). Nassar, J. M.; Ramirez, N. // Plant Systematics & Evolution;Sep2004, Vol. 248 Issue 1-4, p31
We examined the reproductive biology of Melocactus curvispinus Pfeiffer (Cereeae, Cactoideae) in xeric areas of northern Venezuela. Floral traits correspond to a classic hummingbird-pollination syndrome; however, pollination is shared between hummingbirds, Leucippus fallax (Bourcier 1843), and...
- CHAPTER 7: Goldenrod. // Discover Nature Close to Home;1993, p83
This chapter describes the goldenrod, one of the flowers that bloom in late summer. Their yellow hue alerts insects to vast stores of pollen and nectar. Nectar is the sweet liquid produced by flowers and stored in nectaries at their bases. Goldenrod belongs to the daisy or composite or...
- Pollination Biology and Seed Production of a Federally Endangered Perennial, Echinacea laevigata (Asteraceae:Heliantheae). Stucky, J. M.; Gadd, L. E.; Arellano, C. // American Midland Naturalist;Jul2012, Vol. 168 Issue 1, p93
Pollination biology and factors affecting reproductive success of the federally endangered Echinacea laevzgata (coneflower) were studied in one large and five small populations. Insect visitor exclusion from flowering heads and pollination treatments showed that seed production was 10x higher in...
