“…The richest families in this inventory, i.e. Marantaceae, Pteridaceae, Poaceae, Lomariopsidaceae, Costaceae and Hymenophyllaceae, are also the richest in environments including non-riparian forests of Central and Eastern Amazon (Costa 2004;Zuquim et al 2008;Costa & Pietrobom 2010;Pallos et al 2016).…”

We conducted an inventory of the fern, lycophyte and non-palm monocotyledon ground-herbs of terra firme riparian forests in the lower Tapajós region of the Brazilian Amazon. Eight 1.5 × 250 m plots, totaling 0.3 hectares, were surveyed along the watersheds of the Cupari and Curuá-Una rivers, located at the Tapajós National Forest, Pará, Brazil. To characterize the ground-herb community, we calculated species richness, abundance and Fisher’s alpha for each plot. To analyze turnover, we compared composition among plots by pairwise Bray-Curtis distance. In total, we sampled 3,130 individuals, 58 species, 27 genera and 20 families of riparian ground-herbs. Marantaceae (14 spp) was the richest family and Poaceae the most abundant family (738 individuals). The fern Triplophyllum glabrum (Tectariaceae) was the most frequent species, observed in 87.5 % of plots. Ground-herbs communities in the studied area have high species turnover, making it necessary to invest time and resources to adequately characterize and manage riparian habitats. The ground-herb community composition observed in the riparian zone here resembles that of other non-riparian forested sites in the Amazon with the plant families Marantaceae, Pteridaceae and Poaceae generally being the most commonly represented in the Amazonian ground-herb stratum. We highlight the importance of herb inventories, especially in conservation units.

“…In the state of Pará, until the beginning of last decade, little was known about the composition of the fern and lycophyte flora, besides the pioneering studies of Huber (1898Huber ( , 1902Huber ( , 1906, Sampaio (1930), Cain et al (1956) and Pires (1992). However, from 2003 on, there was a great advance in the knowledge about seedless vascular plants in Pará state due to several floristic and taxonomic studies carried out in forest fragments located around the state capital, Belém (Rodrigues et al 2004;Costa et al 2006;Costa & Pietrobom 2007Maciel et al 2007;Ferreira et al 2009;Miranda 2009;Silva 2009), and also in Castanhal (Tavares 2009), Tomé-Açu (Maciel 2008;Maciel & Pietrobom 2010a,b), Portel (Silva & Rosário 2008;Pietrobom et al 2009), Salgado (Costa 2009), Tucuruí (Fernandes et al 2012), Redenção (Fonseca 2010), Monte Alegre (Silva 2010), and in the protected areas of "Calha Norte" (Góes-Neto 2011), as well as new records and other studies (Góes-Neto & Pietrobom 2012a,b;Almeida & Salino 2015;Pallos et al 2016), which have contributed significantly to improve the knowledge on the fern and lycophyte flora in Pará and in the Amazon region.…”

Ferns and lycophytes from Serra dos Carajás, an Eastern Amazonian mountain range

2018

In the state of Pará (Brazil), until the beginning of last decade little was known about the composition of the fern and lycophyte flora. The ferruginous mountains of Carajás are located in Southeastern Pará, mostly inserted in the Floresta Nacional de Carajás. The objective of this work is to present a complete and updated list of fern and lycophyte species occurring in all vegetation types from Carajás ferruginous mountains as a contribution to the knowledge of these plant groups from the Brazilian Amazon. The species list was based on specimens collected between 2007 and 2013. About 1068 specimens deposited in the BHCB Herbarium were studied. A total of 186 species of pteridophytes were recorded, 175 species of ferns distributed in 22 families and 68 genera, and 11 species of lycophytes distributed in three families and four genera. The fern and lycophyte flora of Serra dos Carajás region corresponds to 64% of the Pará state flora of these groups and 34% of the Brazilian Amazon fern and lycophyte flora. Seven taxa are presented as new records for Pará state: Asplenium abscissum, A. otites, A. praemorsum, Blechnum lanceola, Elaphoglossum minutum, Doryopteris collina, and Hemionitis tomentosa. Three species are endemic to Serra dos Carajás, Isoetes cangae, I. serracarajensis, and Selaginella stomatoloma.

“…Nos últimos dez anos, foram produzidos estudos sobre distribuição e abundância das licófitas/ monilófitas em várias regiões do Brasil, como por ex. Pereira et al (2011) em Pernambuco, Schneider & Schmitt (2011) no Rio Grande do Sul, Pallos et al (2016) no Pará e Santos et al (2014) na Bahia. No Nordeste brasileiro, podem ser encontrados vários estudos sobre este grupo de plantas (Pereira et al, 2011;Santiago et al, 2014;Santos et al, 2014;Costa et al, 2018).…”

Foi verificada a distribuição, feita a identificação taxonômica e a caracterização morfológica das espécies de monilófitas (samambaias) aquáticas de quatro lagoas pequenas temporárias e duas perenes localizadas ao longo da estrada que corta o setor industrial da área Itaqui-Bacanga, na ilha de SãoLuís - MA, durante o período de junho a setembro de 2011. As espécies encontradas nos ambientes amostrados foram Salvinia auriculata, Salvinia molesta (Salviniaceae) e Ceratopteris thalictroides (Pteridaceae). As três espécies apresentaram caráter de ocorrência anual e as Salviniaceaeestiveram amplamente distribuídas nos ambientes aquáticos observados. Dentre as monilófitas amostradas, apenas o gênero Salvinia apresenta heterosporia, com a presença de megasporângios e microsporângios. O gênero Ceratopteris, por sua vez, é homosporado, apresentando apenas esporos masculinos, que possuem um potencial para desenvolver gametófitos que futuramente poderão ser masculinos ou hermafroditas. A superfície foliar (tricomas), no caso de Salvinia, e o caule, no caso de Ceratopteris, são importantes estruturas na flutuabilidade das plantas. As três espécies apresentam adaptações morfológicas fundamentais para o seu estabelecimento e desenvolvimento nesses locais.Distribution, morphology and anatomy of aquatic Monilophyta (ferns) in small ponds at the area Itaqui-Bacanga, São Luís Island-MAABSTRACTDistribution, taxonomic identification and morphological analysis of aquatic species of Monilophyta (ferns) were carried out in four perennial and two temporary ponds located along the road through the industrial area Itaqui-Bacanga, at the São Luís Island – MA, from June to September 2011. The species found in the study sites were Salvinia auriculata, Salvinia molesta (Salviniaceae) and Ceratopteris thalictroides (Pteridaceae), all presenting an annual occurrence in nature and Salviniaceae were widely distributed in the ponds observed. Among the monilophytes sampled, only the Salviniagenus shows heterosporia, with the presence of megasporangia and microsporangia. The genus Ceratopteris in turn is homosporate, presenting only male spores, which have a potential to develop gametophytes that in the future may be male or hermaphrodite. The leaf surface (trichomes), in the case of Salvinia, and the stem, in the case of Ceratopteris, are important structures in the buoyancy of plants. The three species show important morphological adaptations for their establishment and development in these places.Keywords: Aquatic euphillophyta; Occurrence; Morphological adaptations; Ponds.
