Ombrophilous Forest

A floristic survey of pteridophytes (ferns and fern allies) was carried out in a 1ha plot in the Pico do Marumbi State Park, Morretes, State of Paraná, Southern Brazil. The study area is covered with a closed ombrophilous forest (Brazilian Atlantic Forest) and lies approximately 630 m in elevation. All species and life-forms of pteridophytes growing in the plot were registered and most of them were collected for taxonomic identification. A total of 81 species, belonging to 17 families were registered. The richest were Polypodiaceae (12 species), Hymenophyllaceae (11) and Lomariopsidaceae (11). The richest genera were Asplenium (ten species), Elaphoglossum (10) and Trichomanes (six). Life-form composition was: epiphytes (49 species), terrestrials (28), lithophytes (two), epiphytes/terrestrials/lithophytes (one) and epiphytes/lithophytes (one). No hemiepiphytes were found. Terrestrials included herbaceous (22 species), arborescent (four) and climbing (two). Species richness of the plot can be considered as high when compared to other neotropical sites.

Abstract We present a checklist for the ferns and lycophytes from Pico Paraná State Park, in Southern Brazil. The Park is entirely located at the Serra do Mar mountains, and represents an important remnant of the Atlantic Rain Forest with altitude achieving 1,887 m. In this locality is the Pico Paraná, the highest mountain in Southern Brazil. This study was focused on the altitudes above 1,000 m, which are mainly represented by dwarf forests and altitudinal fields. A total of 142 species were recorded, three of them (Ceradenia maackii, Diplazium tamandarei, and Stenogrammitis wittigiana) are only found in the park in Southern Brazil. Besides of the checklist of the species, we highlight some important aspects related to endangered species, geographic distribution, and life forms. The high level of endemism, the presence of endangered species, and the phylogenetic diversity as represented by distinct families of ferns and lycophytes show the biogeographic importance of this area for the conservation of these groups of plants.

The Relationship

The reciprocal importance of bromeliads and hummingbirds has been proposed for many years, even suggesting coevolution between these two groups. Nevertheless, data are lacking that allow a better test of the relationships involved. Here we investigate the relationship between bromeliads and hummingbirds in an area of secondary Atlantic rain forest in southern Brazil. The study examined the interactions among 12 species of bromeliad and 10 of hummingbird at Reserva Natural Salto Morato, Paraná state. The number of flowering species of bromeliad and the species richness and abundance of hummingbirds were quantified monthly between November 2004 and October 2005. Focal observations on each bromeliad species were made to determine the hummingbird visitors. Neither species richness nor abundance of hummingbirds were related to bromeliad phenology. Together with the monthly variation in visit frequency by a given pollinator to a given plant, these factors indicate a generalization in the use of bromeliads by hummingbirds and argue against tight coevolution. Ramphodon naevius and Thalurania glaucopis were the main pollinators in the community. Aechmea nudicaulis was the most generalist bromeliad species. The generalist species interacted with other generalists or with asymmetric specialists and there was no specialist–specialist interaction. This produced a strongly organized and nested matrix of interactions. This nestedness is similar to other plant-pollinators networks, supporting the hypothesis that the evolutionary relationship between bromeliads and hummingbirds is no stronger than that of other pollination networks.

Floristic Survey

In the northeastern region of the State of Rio Grande do Sul in Southern Brazil, specifically in the Rio dos Sinos basin, urban parks are an important alternative for the conservation of the remaining natural habitats, as well as for the maintenance and perpetuation of biodiversity. A floristic survey of fern and lycophyte species in the Parque Municipal Henrique Luís Roessler (PMHLR) (29º 41' S and 51º 06' W; alt. 16.4 m) in Novo Hamburgo, (State of Rio Grande do Sul, RS) described their life-forms, as well as substrates and preferential environments. Forty-three species, 30 genera and 15 families were found, 39 of which were ferns. The hemicryptophytes had the highest species richness (26), 17of which were repent, and nine, rosulate. Most species were found in terrestrial substrates (32) and inside the forest (29). Species richness in the PMHLR corresponded to about 13% of the total fern and lycophyte species listed for the State of Rio Grande do Sul, which demonstrates the importance of conservation areas in the Rio dos Sinos basin as an alternative to the preservation of local biodiversity.

<p><strong>Background: </strong>Mexico has a high diversity of aquatic and subaquatic plants that occur between 1,000 and 2,500 m of elevation, although a larger proportion of aquatic plants is concentrated at lower altitudes. Temporary wetlands harbor close to 73 % of the aquatic species in Mexico. These systems are under a strong anthropogenic pressure and suffer constant degradation.</p><p><strong>Questions:</strong> i) How many species grow in highland temporary wetlands? ii) Are they floristically similar? iii) Is there a latitudinal pattern of species richness?</p><p><strong>Studied groups: </strong>Charophyta, Pteridophyta, Angiosperms.</p><p><strong>Study site and years of study:</strong> Central Mexico (39 wetlands) from 2015 to 2016.<strong></strong></p><p><strong>Methods: </strong>We collected in 39 temporary wetlands for two years. We made a presence/absence list of species per locality, and calculated floristic similarities and correlations between wetlands. We include data characterizing life form, plant use, and conservation status.</p><p><strong>Results:</strong> We found 126 species belonging to 80 genera and 38 families. The richest families were Cyperaceae, Asteraceae, and Poaceae. As to genera, <em>Eleocharis</em>, <em>Cyperus</em>, and <em>Juncus </em>had more species. Species with the widest distributions were <em>Persicaria mexicana</em>, <em>Marsilea mollis</em>, <em>Luziola fluitans</em>, <em>Heteranthera peduncularis</em>, and <em>Nymphoides fallax</em>.  We found five different life forms – all herbaceous, including 27 threatened species, 24 species with economic use, 48 endemic species, and 19 cosmopolitan species. In addition, we found 20 species recorded for the first time in some states included in our study, and two species of <em>Eleocharis</em> that might represent undescribed species. The richest wetland harbors 40 species, the poorest has only five. Wetlands were comparable to each other in species composition, and species richness increases towards the south.</p><p><strong>Conclusions:</strong> Temporary wetlands harbor a high floristic diversity and are similar to each other. Lower latitudes host higher numbers of species.</p>

This study examined species richness and relative abundance of eusocial Apidae in an insular region of rain-forest, southeastern Brazil. Sampling took place during one year, using an standardized method with entomological net, at sites of secondary growth habitats surrounded by Atlantic rain-forest. Thirteen species of eusocial Apidae were netted at flowers, over 80% of the captured individuals were meliponine species, although the presence of Apis mellifera, commonly dominant in Brazilian habitats. Foraging activity of these bee species were essentially non-seasonal, apparently affected by high humidity. The patterns in abundance and species richness observed in Ilha Grande differed with other studies conducted at tropical islands, which were characterized by the poverty of meliponine species.
