Inherent characteristics of island species make them particularly susceptible to anthropogenic changes and need to be assessed to implement appropriate conservation strategies. The impacts of climate change are increasingly being investigated along …
A vittarioid fern from the Solomon Islands, which has long been treated as *Antrophyum semicostatum*, is described here as a new species, *Antrophyum solomonense* . A description, illustration, and distribution of the new species are presented. …
__*Premise of the Study.*__ Ferns and lycophytes are the only extant land plants with two free-living generations (sporophytes and gametophytes); hence, a single species may have two different distributions. The distribution of the gametophytes of …
__*Premise of the Study.*__: Hybridization is an important mechanism of speciation in plants and often results in complexes that comprise multiple sexual diploids and their hybrid offspring. However, the intricacy of these systems has prevented a …
The ferns and lycophytes of Mo'orea, French Polynesia were surveyed as part of the Mo'orea Biocode Project during September 12–13, 2006, September 6–27, 2008, and August 11–28, 2010, resulting in collection of 42 species that had not been previously …
__*Background.*__ DNA barcoding is expected to be an effective identification tool for organisms with heteromorphic generations such as pteridophytes, which possess a morphologically simple gametophyte generation. Although a reference data set …
Pacific species of *Hymenophyllum* subgen. *Sphaerocionium*, *Mecodium*, *Globosa*, *Pleuromanes*, *Myrmecostylum*, *Fuciformia*, *Diploöphyllum* and *Cardiomanes* are enumerated. In total, 37 species are recorded in the studied area, and synonymies, …
Hemi-epiphytism represents an evolutionarily important yet poorly understood growth habit in ferns. Anatomy and ontogeny related to hemi-epiphytism in the fern *Vandenboschia collariata* (Hymenophyllaceae) were investigated at La Selva Biological …
*Polyphlebium borbonicum* is newly recorded in Central and South America and Easternmost Polynesia (Marquesas and Society Islands). It has been misidentified as *P. diaphanum* and as *P. endlicherianum* in the New World and in the Pacific, …
The Moorea Biocode seeks to compile an integrative taxonomy based on morphological, ecological, and molecular data for the entire macrobiota of the island of Moorea, French Polynesia. As a case study exploring the utility of selected molecular data …
