Gametophyte ecology and demography of epiphytic and terrestrial tropical ferns.
Factors 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. The goal of this study was to examine demography and the influence of light and disturbance on the distribution of the gameto...
متن کاملThirteen new records of ferns from Brazil
Thirteen fern species are reported for the first time for Brazil. Among the new records, eight are from Acre state (Cyatheasubincisa, Cyclodiumtrianae, Elaphoglossumstenophyllum, Hypoderrisbrauniana, Pleopeltisstolzei, Thelypterisarcana, Thelypteriscomosa, Thelypterisvaldepilosa), two are from Pará state (Polypodiumflagellare, Tectariaheracleifolia), one from Minas Gerais state (Alsophilasalvin...
متن کاملStasis and convergence characterize morphological evolution in eupolypod II ferns.
BACKGROUND AND AIMS Patterns of morphological evolution at levels above family rank remain underexplored in the ferns. The present study seeks to address this gap through analysis of 79 morphological characters for 81 taxa, including representatives of all ten families of eupolypod II ferns. Recent molecular phylogenetic studies demonstrate that the evolution of the large eupolypod II clade (wh...
متن کاملComisión Interamericana Del Atún Tropical Inter-american Tropical Tuna Commission
This paper presents overall scientific estimations on bycatch landings by species, or groups of species, carried out by the Spanish surface longline fleet targeting swordfish (Xiphias gladius) in the Pacific Ocean. The mean level of bycatch landed by the Spanish fleet from the beginning of the fishing activity in 1990 until the year 2005 accounted for 42.6% of the total weight landed (target sp...
متن کاملThe inXuence of life form on carbon and nitrogen relationships in tropical rainforest ferns
Tropical ferns are characterized by a high diversity of plant life forms, yet there have been few largescale studies on the functional ecology of these diVerent forms. We examined epiphytic, hemiepiphytic, and terrestrial ferns, and asked whether there are diVerences in the mineral nutrition and water relations across diVerent growth forms of a diverse assemblage of species. We measured speciWc...
