Gametophyte ecology and demography of epiphytic and terrestrial tropical ferns
American Journal of Botany, 2007Factors that influence the distribution of ferns are poorly understood and likely reflect the ecology of both the sporophyte and the gametophyte generation. Little study has been done on the ecology of the gametophyte generation, especially in regard to tropical species.

Control of branching pattern in Microgramma vacciniifolia, an epiphytic fern
Planta, 1975The rate of expansion of lateral buds of Microgramma vacciniifolia (Langsd. et Fisch) Copeland (Polypodiaceae) does not differ in intact plants, in plants with the rhizome apex removed, and in plants with the apex removed and replaced with indole-acetic acid (IAA).

Tree-Fern Skirts: A Defence Against Climbers and Large Epiphytes
The Journal of Ecology, 1986SUMMARY (1) The retention of dead fronds as a fringing 'skirt' around the trunks of tree-ferns is a feature seen in many species in different parts of the world. (2) It is suggested, from observations of cultivated tree-ferns and the native species of New Zealand, that such skirts, in combination with other habits, may deter climbing plants from ...

Gas Exchange and Water Relations in Epiphytic Tropical Ferns
1989The abundance of epiphytes is a characteristic feature of the rich vegetation of the wet tropics. Among the epiphytic vascular plants ferns are quite frequent (Chaps. 2, 3 and 9). According to Holtum (1969), about half of the some 500 known fern species in Malaysia are epiphytes. Recently the ecophysiological problems linked with epiphytism are gaining

Divergence Times and the Evolution of Epiphytism in Filmy Ferns (Hymenophyllaceae) Revisited
International Journal of Plant Sciences, 2008Although the phylogeny of the filmy fern family (Hymenophyllaceae) is rapidly coming into focus, much remains to be uncovered concerning the evolutionary history of this clade. In this study, we use two data sets (108‐taxon rbcL + rps4, 204‐taxon rbcL) and fossil constraints to examine the diversification of filmy ferns and the evolution of their ...

The suitability of the epiphytic fern Lepisorus thunbergianus (Kaulf.) Ching, common in East and Southeast Asia, for the in situ biomonitoring of atmospheric mercury levels was investigated. L. thunbergianus is an evergreen fern with young, mature and old fronds throughout the year.

Degrees of crassulacean acid metabolism in tropical epiphytic and lithophytic ferns
Australian Journal of Plant Physiology, 1999Crassulacean acid metabolism (CAM) was observed in three species of tropical ferns, the epiphytes Microsorium punctatum and Polypodium crassifolium and the lithophyte Platycerium veitchii . Polypodium crassifolium and P. veitchii exhibited characteristics of weak CAM.

Adaptation of a widespread epiphytic fern to simulated climate change conditions
Plant Ecology, 2014The response of species to climate change is generally studied using ex situ manipulation of microclimate or by modeling species range shifts under simulated climate scenarios. In contrast, a reciprocal transplant experiment was used to investigate the in situ adaptive response of the elevationally widespread epiphytic fern Asplenium antiquum to ...

Pleopeltis is a genus of the family Polypodiaceae, whose circumscription is still unresolved. The genus comprises about 90 species distributed mainly in the Neotropics. The apomorphies of the genus include the presence of persistent peltate scales and foliar nectaries. In Argentina, Pleopeltis macrocarpa (Bory ex. Willd.) Kaulf.
