Opis:
The genus Eulophia embraces over 230 species distributed through the tropical and subtropical Africa, Asia, Australia and the Americas. In Neotropics it is represented by a sole species – E. alta. The aim of the presented study was to evaluate the difference between ecological niches occupied by American and African populations of this species based on the ecological niche modeling. The similarity between the glacial and present niches occupied by E. alta was calculated and the factors limiting the species occurrence were identified. Areas of seasonal tropical forest, tropical savanna and woodland served as refugia for the studied species during last glacial maximum and they were more widespread in Neotropics than in Africa. No significant niche shift after last glacial maximum was observed. The distribution of E. alta in its whole range is restricted mainly by temperature seasonality. The differences in the niches occupied by African and Neotropical populations of E. alta suggest preglacial disjunction of the species range and independent adaptation of both groups. Despite the significant range disjunction of E. alta the species is characterized by relatively high degree of niche conservatism.

Opis:
Two American species of moss, Ephemerum homomallum Müll. Hal. (Pottiaceae) and Torrentaria aquatica (A. Jaeger) Ochyra (Brachytheciaceae), are reported as new to Africa, based on collections from the Limpopo and Eastern Cape provinces of South Africa, respectively. These discoveries changed the phytogeographical status of both species, which now belong to the Afro-American distribution element. Global geographical ranges of these two species are reviewed and mapped, and the amphiatlantic distribution pattern of mosses is briefly summarized. A history of the muscological exploration of southern Africa is briefly considered and recent additions to the moss flora of this area are reviewed.

Opis:
Epibiosis is a facultative association between two organisms: the epibiont, which colonizes the surface of living substrates, and the basibiont, which hosts the epibionts. Among protists, while numerous accounts exist for ciliates as epibionts of zooplankton, little information is available about the occurrence of this relationship between flagellates and microcrustaceans in the neotropics. During a survey on the epibiotic relationship between ciliated protists and planktonic copepods in a tropical floodplain, we reported for the first time the occurrence of Colacium vesiculosum as an epibiont on Thermocyclops minutus and Notodiaptomus amazonicus from southern Brazil. The mean infestation prevalence was significantly higher on adults 30.53% (± 2.85) in comparison with copepodites 0.87% (± 0.55). When hosts were separated by order (Calanoida and Cyclopoida) copepodites presented a mean infestation prevalence of 0.92% (± 0.85) and 0.83% (± 0.60) respectively, while adults had a mean prevalence of 29.55% (± 6.8) and 30.13% (± 5.83), which could be explained by the fact that adult copepods provide a more stable substrate for epibionts.

Opis:
Pleurothallidinae with more than 5000 species are the most diverse and numerous group of orchids. This subtribe occurs exclusively in tropical America, with a range extending from Florida and the Caribbean on the north to the northern parts of Argentina on the south. Pleurothallids are predominantly epiphytes growing above 1000 m a.sl. Taxonomical studies reveal new species each year. Herein we propose 5 new species representing Stelis, Lepanthes and Muscarella.
