LINKING FLORISTIC PATTERNS WITH SOIL HETEROGENEITY AND SATELLITE IMAGERY IN ECUADORIAN AMAZONIA
Florisitic ground surveys in tropical rain forests are laborious and time consuming, so we tested to what degree reflectance differences visible in Landsat Thematic Mapper (TM) satellite images can…
A community‐derived classification for extant lycophytes and ferns
A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.
Species richness and distribution of ferns along an elevational gradient in Costa Rica
Little evidence is found that environmental gradients drive patterns of fern species richness on this spatial scale, and mean annual rainfall and temperature, light intensities in the canopy and at ground level, and the mid-domain effect are examined.
Molecular phylogeny of the fern genus Elaphoglossum (Elaphoglossaceae) based on chloroplast non-coding DNA sequences: contributions of species from the Indian Ocean area.

- 1 December 2004
The results of this expanded study largely agree with an earlier molecular study based on a smaller group of neotropical species and with the morphology-based classification of Mickel and Atehortua, but it is found that some infrageneric groups such as section Elaphoglossum are not monophyletic.
A natural history of ferns
- R. Moran
"A Natural History of Ferns" is an entertaining and informative look at why ferns and their relatives are unique among plants, and Moran sheds light on Robinson Crusoe's f Ferns, the role of f Verns in movies, and how fernS get their names.
Phytogeographic relationships between neotropical and African-Madagascan pteridophytes
The purpose of this study is to determine the floristic affinities of pteridophytes between the neotropics and Africa-Madagascar and examine how theseAffinities might have arisen and assess three hypotheses: the boreotropics hypothesis, continental drift, and long-distance dispersal.
Biology and Evolution of Ferns and Lycophytes: Diversity, biogeography, and floristics
- R. Moran
- 1 June 2008
Introduction The biogeography of ferns and lycophytes can be studied from several points of view and with various methods. It might, for instance, examine the distribution of species on a single tree…
Monograph of the Neotropical Fern Genus Polybotrya (Dryopteridaceae)
- R. Moran
- 30 November 1987
The morphological and anatomical evidence presented here suggests that Polybotrya may have evolved instead from a Cyclodium-like ancestor, and may well provide insight into broader questions of fern evolution.
Molecular Studies of Representative Species in the Fern Genus Elaphoglossum (Dryopteridaceae) Based on cpDNA Sequences rbcL, trnL‐F, and rps4‐trnS

- 1 November 2004
Mapping of morphological characters onto the molecular phylogeny reveals how scale structure, rhizome morphology, presence/absence of hydathodes and/or phyllopodia, and general growth form are important synapomorphies for sectional and subsectional classification in Elaphoglossum.
A Neotropical Companion: An Introduction to the Animals, Plants, and Ecosystems of the New World Tropics
This second edition of A Neotropical Companion has been substantially revised and expanded to incorporate the abundance of new scientific information that has been produced since it was first published in 1989.
