- The role of pollen limitation on the coexistence of two dioecious, wind-pollinated, closely related shrubs in a fluctuating environment. Cázares-Martínez, Juana; Montaña, Carlos; Franco, Miguel // Oecologia;Nov2010, Vol. 164 Issue 3, p679
Elucidating the mechanisms of species coexistence is a crucial goal in ecology. Theory suggests that, when resource abundance fluctuates, coexistence can be achieved if each species in a competing pair is better at exploiting resources at opposite extremes of a fluctuating resource spectrum....
- Revisiting the Neotropical Genera Chelyocarpus, Cryosophila and Itaya (Coryphoideae: Cryosophileae). CASTAÑO, G. FELIPE; SPICHIGER, RODOLPHE; STAUFFER, FRED W. // Palms;Jun2011, Vol. 55 Issue 2, p72
The article discusses the taxonomy and morphology of the three palm genera Chelyocarpus, Cryosophila and Itaya. It notes that this palm group has an interesting taxonomic and evolutionary horticultural potential through its beautiful leaves and spectacular inflorescences. It details the plant...
- Intensity and diversity of flower-visiting insects in relation to plant density of Zizyphus mauritiana Lamk. Mishra, R.M.; Gupta, Pushplata; Yadav, G.P. // Tropical Ecology;Winter2004, Vol. 45 Issue 2, p263
The floral syndrome of Zizyphus mauritiana Lamk. (Rhamnaceae) reflects its adaptation to insects. We examined the blossom visitor assemblage of Z. mauritiana in relation to plant density. Results indicate that flowers of this plant species are visited by 86 species of insects which consisted 32...
- Genetic diversity of Balanophora fungosa and its conservation in Taiwan. Shu-Chuan Hsiao; Wei-Ting Huang; Maw-Sun Lin // Botanical Studies;2010, Vol. 51 Issue 2, p217
Balanophora fungosa is a rare holoparasitic flowering plant in Taiwan, where it is restricted to the Hengchun Peninsula in southernmost Taiwan, and Orchid Island (Lanyu in Chinese), a small volcanic island off the southeastern coast of Taiwan. Plants from these two areas appear in two different...
- Ecotypic Variation among European Arctic and Alpine Populations of Oxyria digyna. Heide, Ola M. // Arctic, Antarctic & Alpine Research;May2005, Vol. 37 Issue 2, p233
Morphological and physiological variation of four geographically separated European populations of Oxyria digyna (L.) Hill (Polygonaceae) ranging from 45 to 78Â°N latitude were studied in controlled environments. Characters such as the presence of rhizomes, variable stamen number, few...
- SEED WEIGHT RESPONSES TO REMOVAL OF PEDICELLATE SPIKELETS IN HERMAPHRODITIC BIG BLUESTEM. Boe, Arvid; Similien, R. M. // Proceedings of the South Dakota Academy of Science;2011, Vol. 90, p208
Andromonoecy is the predominant form of sex expression in big bluestem (Andropogon gerardii Vitman), but plants with perfect pedicellate spikelets occur in some populations in the Great Plains. Low seed set in andromonoecious big bluestem suggests seed production is resource limited. On the...
- The status and population structure of the marula in the Kruger National Park. Jacobs, O.S.; Biggs, R. // South African Journal of Wildlife Research;2002, Vol. 32 Issue 1, p1
Presents a study which examined the population structure of the marula trees in the Kruger National Park in South Africa. Review of related literature; Description of the study area; Data and methods used; Findings and its implications.
