| Here, we present the current state of knowledge on the diversity of Chilean bryophytes (mosses, liverworts, and hornworts), the secondary metabolites present in these plants, and the biological activity of extracts from populations of Chilean species. Our goal is to establish the potential of these plants as a source of useful molecules for pharmaceutical and agricultural industries, thus promoting their conservation. Only 3,7% of Chilean bryophytes (55 spp.) have been analyzed using chemical characterization of their extracts (methanol, ether, ethanol, dichloromethane, acetone and hexane). Only four species from Chilean and Argentinian populations (Porella chilensis (Lehm. & Lindenb.) Trevi., Riccardiapolyclada (Mitt. ex Thurn) Hässel,... |

| The moss flora of Mindoro Island was updated based on the 2004–2006 expeditions conducted by the author. The island’s moss flora now consists of 282 species in 128 genera and 39 families, which is higher than Palawan but far less than those of Luzon and Mindanao. Generally, the flora is most abundant in the eastern rainy part of the island, especially along mid-elevations on the east-facing slope of the central mountain range in the transition zone between montane and mossy forests. Moss diversity is also greater in riverine forests than in inland forests at low elevations. Only three moss taxa, Rhaccocarpus alpinus, Dicranoloma daymannianum and Distichophyllum noguchianum, have their Philippine range restricted to the island. Distichophyllum noguchianum... |

| Samples and specimens of mosses were collected in different parts of Erbil, Sulaimani, Duhok and Even Kirkuk provinces in Iraq Kurdistan Region, since 1998 to April 2010. This collection could be taken as the representative species of mosses on the soil surface, rocks and tree barks of either terrestrial and aquatic habitats of foothills, mountains and plains. A total of 67 species distributed in 32 genera, 16 families and 9 orders were found. Among them there were 17 species in 10 genera, the 2 families Schistogaceae and Ephemeraceae and the single order Schistostegales. The rarest species recorded in this study were Schistostega pennata with fern-like leaves within a Shanadar cave, Pottia wilsoni var. crinata, at the entrance of Ba-stoon cave, and... |

| Mosses and liverworts can be colonized by various invertebrates, including fresh water oligochaete worms. However, little information is available on the habits and habitats of this oligochaetes in Brazil. Therefore, the present study was undertaken to examine the occurrence of naidids in mosses, as well as to broaden the knowledge about the habitats of these oligochaetes. Sampling of bryophytes adhered to rock substrates in the rapids of the Jacaré Pepira River (municipality of Brotas, São Paulo, Brazil) and to a vertical rock wall of a waterfall near the river revealed 191 Naididae individuals of the species Naiscommunis Piguet, 1906, Pristinellajenkinae (Stephenson, 1931) and Pristinellamenoni (Aiyer, 1929). We believe this to be the first record of... |

| Epiphytic bryophyte communities in terra firme forests of the Amazon region were investigated for the first time through standardized sampling across the Amazon basin. The sampling was carried out at nine localities, where bryophytes were collected in five height zones, from the forest floor to the canopy of eight canopy trees per locality. The sampling generated 3104 records, identifying 222 species and 39 morphospecies, within 29 families. The most common families were Lejeuneaceae (in 55%), Calymperaceae (in 8%), Leucobryaceae (in 4%) and Sematophyllaceae (in 4%). Richness and species composition did not show any geographical gradient. The bryoflora was significantly richer in the localities of Saül, in French Guiana, and Tiputini, in Ecuador, than in... |

| The Chapada Diamantina ecoregion is within the caatinga (shrublands) biome of Brazil. Environmental factors determine the phytophysiognomies that distinguish the ecoregion from the surrounding areas. This study aimed to investigate the distribution of bryophyte flora in this ecoregion, by phytophysiognomy and elevational zone. Analyzing specimens we collected from five municipalities in the region, together with specimens (previously collected from the region) in herbaria, we identified 400 taxa. The phytophysiognomies that presented the highest species richness and the greatest numbers of exclusive taxa were forests and campos rupestres (dry, rocky grasslands), which respectively accounted for 51% and 40% of the taxa, compared with only 5% and 4%,... |

| Serra do Cipó has attracted the interest of many researchers over the years because of its unique characteristics, particularly the fact that the site represents the transition between Cerrado and Atlantic Forest. The study area of Serra do Cipó is located along a gallery forest "córrego Três Pontinhas," at 19°16'00" S and 43°32'49" W and an altitude of 1,188 m. The objective of this study was to survey the Division Bryophyta in a gallery forest within the National Park of Serra do Cipo, Minas Gerais. Collections were made during the months of November 2009 and July 2011. We found 15 families, 26 genera, 43 species, and 4 varieties of mosses. The families with the largest number of species were Leucobryaceae (10), Sematophyllaceae (9), and Calymperaceae... |

| Bryophytes constitute an important component of tropical rain forests, which provide microhabitats favorable for their establishment. Bryophytes are also quite responsive to changes in microclimate, which makes them good bioindicators. This study aimed to determine the diversity and distribution of bryophytes in upper and lower montane forests of the Chapada Diamantina region of the state of Bahia, Brazil. To that end, we studied community aspects such as richness, diversity, substrates colonized, life forms and floristic similarity between areas and regions. In 2007 and 2008, we collected specimens from six forest sites, located from the north to the south of the Chapada Diamantina region. We identified a total of 205 infrageneric taxa. In comparison with... |

| ABSTRACT The ready availability of water resources distinguishes the humid forest of Chapada do Araripe, Ceará State, Brazil, from the semiarid vegetation around it. The regional climate demonstrates a marked seasonality of rainfall that affects the ecological strategies of the species found there. We studied the bryophytes of the humid forest of Chapada do Araripe, analyzing their diversity, geographic distributions, and ecological and reproductive aspects. Bryophytes were collected from different substrates using the random-walk method. We gathered information concerning the geographic distribution, functional groups (life forms, light tolerance guilds, and habits) and reproductive aspects of each taxon. We found 76 bryophyte species, predominantly... |
