Determinantes da estrutura da comunidade de pteridófitas na BR 319, interflúvio Purus Madeira Amazonas, Brasil.

TL;DR: In this paper, an annotated list containing 122 species and three varieties of ferns and lycophytes from Biological Reserve of Uatuma, a large reserve that includes small patches of rich soils in Central Amazonia.

TL;DR: In this paper, a survey of lycophytes and ferns from the Parque Metropolitano de Pituacu, Salvador, Bahia State is presented.

TL;DR: This dissertation addresses an issue of key importance to the field of systematics, namely how to foster taxonomic work and the dissemination of knowledge about species by taking full advantage of electronic data and bioinformatic tools.

TL;DR: In this article, a detailed map of botanical collection density is used to identify the true concentrations of plant endemism, which is important for selecting priority conservation areas to guarantee preservation of unique species.

TL;DR: It is argued that a similar general framework of weaknesses and strengths is likely to have operated in the past, and thus have been of similar relevance in defining and promoting the ecological achievements of the fossil pteridophytes in relation to selection pressures and consequent adaptations.

TL;DR: In this article, the authors characterize the sedimentary successions formed in the Brazilian Amazon in the Neogene-Quaternary discussing the evolution of the depositional systems through time and analyzing their main controlling mechanisms in order to fill up this gap.

TL;DR: The results indicate high turnover in species composition, on spatial scales of 5‐10 km in central Amazonia, which is not necessarily associated with soil change, and knowledge of geographical, historical or other landscape features, such as watershed morphology, may therefore be necessary to predict the turnover patterns over mesoscales.
