“…This southern limit is remarkable to orchids (10 of 12 species), ferns (13 of 25 species), and to the genus Peperomia (six of seven species) and Ficus (all the species in the country). This distributional trait of epiphytes was previously reported for orchids (Waechter 1998;Rossado et al 2014) and peperomias (Mai et al 2016), and is furthermore shared with many terrestrial woody species (Grela & Brussa 2003;2005;Brussa & Grela 2007;Delfino et al 2011;Haretche et al 2012;Brussa 2016). The epiphytic examples given above reinforce the transitional nature of the Uruguayan flora, despite a single biogeographic province (Pampean) is commonly assigned to the entire country.…”

“…Conservation status: EN. The species was cited for Uruguay some years ago (Rossado et al 2014) so, it is not included as a priority for conservation in Uruguay by Marchesi et al (2013). As it was previously suggested in Rossado et al (2014), we consider it relevant to add A. hygrophila to the list of species considered as a priority for conservation in Uruguay.…”

“…Nevertheless, there are no studies concerning the entire epiphytic flora of Uruguay and the relationships of this flora with forest types. Most of the present knowledge on vascular epiphytes is addressed in taxonomic studies of families or groups containing epiphytic species, such as ferns (Osten & Herter 1925;Herter 1928;1939;1949;Legrand & Lombardo 1958;Marchesi 1964;1979;Mai 2014), peperomias (Trelease [1939(Trelease [ ]1941Trelease & Herter 1952;Marchesi 1968;Mai et al 2016), orchids (Izaguirre 1972;1985;2013;Rossado et al 2014), bromeliads (Smith 1933;Marchesi 1965;Smith & Downs 1977;Brito & Llano 2008;Rossado 2018;Rossado et al 2018a;b;2019), tradescantia (Pellegrini 2018), ficus (Herter 1940;Brussa & Grela 2007) and cacti (Herter 1930;Lombardo 1946;Eggli et al 2008;Berazategui et al 2010).…”

Catalogue of the vascular epiphytic flora of Uruguay

et al. 2019

We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was the most diverse ecological category. More than half of the epiphytic species documented for Uruguay (53 %) reach their southernmost geographic distribution in the country, whereas only two mostly epipetric species of Tillandsia-T. arequitae and T. uruguayensis-are endemic to the country. Almost half of the epiphytic species found are presently under categories of threat of extinction, with 60 % of them occurring in national protected areas. Both the richest epiphytic families and the predominance of characteristic holoepiphytes coincide with findings from floristic and ecological studies previously carried out in humid subtropical regions.

“…presentes en el país. En los últimos años, Izaguirre (2010 y Rossado et al (2014) registran aproximadamente 60 especies en 18 géneros, siendo la mayoría de hábito terrestre y únicamente nueve epífitas. Entre ellas, 12 especies en nueve géneros son indicadas como nuevos registros para el país y Mai et al (2019) publican un catalogo de la flora vascular epífita del país con 12 especies de la familia en siete géneros.…”

Lista comentada de Orchidaceae en Uruguay y su distribución en ambientes y eco-regiones

2020

Orchidaceae es una de las familias botánicas más estudiadas desde el punto de vista taxonómico y económico en el mundo. En Uruguay es poco conocida y los datos descriptivos que existen se encuentran fragmentados y dispersos. En este trabajo se presenta un inventario de la familia así como su distribución en ambientes, eco-regiones y departamentos del país basados en los registros de herbarios, publicaciones existentes y expediciones de campo realizadas durante el 2018–2019. Se presenta una lista con 59 especies en 18 géneros. Se encontraron cuatro especies endémicas de Uruguay, mientras que 22 spp. son endémicas del Cono Sur. La Cuenca Sedimentaria Gondwánica fue la eco-región en presentar mayor diversidad de especies (51%) y los departamentos con mayor riqueza fueron Cerro Largo (25 spp.) y Maldonado (25 spp.). Mientras que el Bosques Serranos y Bosque Ribereño fueron los más ricos en especies de orquídeas. Los géneros más representativos fueron Habenaria (12 spp.), Cyclopogon (8 spp.) y Brachystele (6 spp.) y las especies que presentaron distribución amplia fue Habenaria gourlieana, H. parviflora, y Cyclopogon elatus, las cuales se encontraron en todas las eco-regiones y en 15 de los 19 departamentos del país. Palabras clave: Cono Sur, Epidendroideae, Neotrópico, Orchidoideae, Sudamérica

Mammals of Paso Centurión, an area with relicts of Atlantic Forest in Uruguay

Paso Centurión is one of the most diverse areas of Uruguay. It is legally protected at local and national level, however, there are different interests competing for its land use and management. With the aim to document the biodiversity of the area together with the local people, the NGO JULANA has been conducting a participatory monitoring process with camera traps since 2013. Here, we present a list of 23 medium and large-size mammal species documented in the area and a standardised dataset of occurrence records. Top observations include the last Chrysocyon brachyurus seen in Uruguay, the first record of Herpailurus yagouaroundi in the country and the second report of Leopardus munoai in the area. We also highlight the frequent observation of numerous rare species such as Tamandua tetradactyla, Leopardus wiedii, Cabassous tatouay, Coendou spinosus and Cuniculus paca. Although the cameras were located within only a few metres of the houses of the local people, some of the rarest and most elusive species in the country were reported. This suggests a possible coexistence between people – their socio-economic practices – and nature in the area. Our work underlines the importance of the recent inclusion of Paso Centurión and Sierra de Ríos to the National System of Protected Areas under the proposed category of ‘Protected Landscape’. Collectively, in a context of global change and lack of biodiversity data on species distribution, we emphasise the value of these records for the knowledge of mammals in Uruguay and the need to extend and continue monitoring this area.
