“…The richest epiphytic families in Uruguay also match overall those found in epiphytic communities of humid subtropical areas in northeastern Argentina (Cabral & Salas 2008;Martín 2014), eastern Paraguay (Basualdo et al 2005) and southern Brazil (Gonçalves & Waechter 2003;Giongo & Waechter 2004;Buzatto et al 2008;Staudt et al 2012;Perleberg et al 2013;Matos et al 2017;Ramos et al 2019). However, in Uruguay Orchidaceae shows a lower contribution when compared with these studies, where it stands as the richest plant family.…”

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.

“…Esta Unidade de Proteção Integral encontra-se inserida dentro dos limites da Área de Proteção Ambiental do Banhado Grande (Figura 1). O Refúgio de Vida Silvestre abrange uma área de 2.543,46 hectares, com formação de banhados, campos secos e úmidos e matas de restinga paludosa e arenosa (Matos et al 2017). Os fragmentos de mata paludosa e arenosa em análise possuem, 10 e 18 hectares, com altitude de 20 e 50 metros acima do mar, respectivamente (Figura 2).…”

“…Em contrapartida, inventários florísticos específicos da região são pouco recorrentes. Encontramos na bibliografia o estudo sobre epífitos vasculares do RVSBP (Matos et al 2017), a análise espaço-temporal da dinâmica da vegetação de macrófitas na área do Banhado Grande (Leite et al 2013), a estrutura sinusal dos componentes herbáceo e arbustivo no Morro Grande (Müller & Waechter 2001) e a estrutura do componente arbóreo da região de Águas Claras, que antecede a criação do Refúgio (Waechter et al 2000). Porém, dados atualizados e específicos do componente arbóreo, bem como da fitossociologia da mata de restinga e paludosa, ainda não haviam sido levantados dentro dos limites desta Unidade de Conservação de Proteção Integral.…”

O objetivo deste estudo foi descrever o componente arbóreo das matas de restinga paludosa e arenosa, ocorrentes no Refúgio de Vida Silvestre Banhado dos Pachecos. Além do levantamento florístico, foram amostradas 20 parcelas de 10 x 10 metros, distribuídas entre os dois sistemas florestais, onde foram incluídos todos os indivíduos com mais de 5 cm de diâmetro à altura do peito (DAP ≥ 5 cm). Foram encontradas 99 espécies, distribuídas em 62 gêneros e 36 famílias. A família que apresentou maior riqueza de espécies foi Myrtaceae (18 spp.). Os habitats paludoso e arenoso apresentaram a mesma riqueza, porém diferiram em estrutura e composição de espécies, como já observado em outros estudos para o ambiente de restinga. A diferença entre ambas formações vegetais se explica, principalmente, pelas condições edáficas em que se encontram, sendo a disponibilidade de água no solo um fator fundamental na seleção das espécies ocorrentes em cada ambiente.

“…In the north of Águas Claras there is a wildlife refuge (nature reserve), Refúgio de Vida Silvestre Banhado dos Pachecos (RVSBP), with an area of 2543 ha. RVSBP is characterized by large wetland areas, wet fields, and forested areas at its northwest, south, and west borders [63]. The four largest forest patches have 65, 161, 258, and 286 ha.…”

Urban Matrices Threaten Patch Occurrence of Howler Monkeys in Anthropogenic Landscapes

Habitat modification due to human activities threatens species survival. While some species can inhabit habitat patches in anthropogenic landscapes, their occurrence often depends on landscape structure. We assessed the effects of landscape structure on brown howler monkey (Alouatta guariba clamitans) occurrence in an urban scenario. We conducted censuses in 59 forest patches from 2014 to 2016 in Rio Grande do Sul State, Brazil. We evaluated patch occurrence (presence/absence) in response to landscape composition (forest cover, arboreal crops, urban areas, open areas, and water) and configuration (patch density), considering the scale of effect. Water, urban, and open areas were the most important predictors of howler presence. Their presence was notably higher in landscapes with more water, likely because these landscapes consist of rural areas with low urbanization, less farming, and relatively high forest cover. Presence of howlers was positively associated with forest cover and negatively related to urban areas, open areas, and arboreal crops. Resource scarcity and increased mortality risks from human pressures, such as domestic dog attacks, electrocution, and roadkill on these land covers may explain these relationships. We highlight the importance of conserving and increasing forest cover in anthropogenic landscapes to protect species reliant on forested habitats, like howler monkeys.
