Morfologia dos esporos de Sematophyllaceae Broth. ocorrentes em três fragmentos de Mata Atlântica, no Rio de Janeiro, Brasil

Abstract: -(Spores morphology from Sematophyllaceae Broth. from three fragments of Mata Atlântica, in Rio de Janeiro, Brazil). In the present work the spores of seven species of the family Sematophyllaceae Broth. (Bryophyta) from three areas of Mata Atlântica were analyzed. For the spores' external morphology analysis, the direct method in glycerined gelatin was used and for the measurements the method of acetolysis was used. The largest and smaller diameters (in polar view) and the thickness of the wall were measured. … Show more

“…The coefficient of variability found here for spore size is comparable to that reported by previous studies of bryophyte spores, which were around 10 % (Luizi-Ponzo & Barth 1998;Caldeira et al 2009), due to the size amplitude observed in bryophyte spores.…”

“…Sim-Sim et al (2017) reconstructed the phylogeny of this genus using morphological and anatomical characters, and indicated six species for the genus: Amphidium lapponicum, A. mougeotii, A. tortuosum, A. californicum, A. curvipes, and A. asiaticum. Palynological studies dealing with bryophyte species have made important advances since the 1980s regarding the taxonomy, ecology, and phylogeny of the group (Mogensen 1981;Luizi-Ponzo & Barth 1998;1999;Luizi-Ponzo & Melhem 2006a;b;Caldeira et al 2006;2009;Rocha et al 2008;Savaroglu & Erkara 2008;Alfayate et al 2013;Rodrigues & Luizi-Ponzo 2015;Silva-e-Costa et al 2017). However, studies on Amphidium have focused mostly on morphological and molecular characters (Rooy 1992;Goffinet et al 1998;Stech 1999;Farge et al 2000;2002;Frahm et al 2000;Tsubota et al 2003;Hedderson et al 2004;Stech 2004;Stech & Frey 2008;Stech et al 2012;Sim-Sim et al 2017), with palynological information on its species remaining rare (Hirohama 1977) or only briefly summarized in some taxonomic studies (Rooy 1992;Gradstein et al 2001;Allen 2002), in which they were described as "subrounded", "small", "apparently ornamented", "slightly papillose" or "having a smooth sporoderm".…”

“…The coefficient of variation for spore size for the species studied here ranged from 8 % to 12 %. A coefficient of variation of around 10 % has been commonly found by palynological treatments of bryophytes, such as Luizi-Ponzo & Barth (1998;, Luizi-Ponzo & Melhem (2006), Rocha et al (2008), Caldeira et al (2009;, Yano & Luizi-Ponzo (2011), and Rodrigues & Luizi-Ponzo (2015). Heinrichs (2002) stated that the average size of spores of Plagiochila vary considerably, while reported ca.…”

“…No presente estudo, a nomenclatura seguiu a definição de Alfayate et al (2013). A predominância desse tipo de ornamentação encontrada nos esporos de Chryso-hypnum e Mittenothamnium apresentadas aqui e nos esporos de espécies de Hypnales, e em outras literaturas (Caldeira et al 2009, Alfayate et al 2013, indicam uma maior representatividade deste padrão de ornamentação (grânulos de tamanho variável, formados pela associação de grânulos menores) nesses esporos.…”
