ESPÉCIES ARBÓREAS DE UM TRECHO DE FLORESTA ATLÂNTICA DO MUNICÍPIO DE ANTONINA, PARANÁ, BRASIL

Com o objetivo de subsidiar futuros estudos de dinâmica da vegetação e efeitos das mudanças climáticas, realizou-se um levantamento florístico do componente arbóreo em área de Floresta Ombrófila Densa da Reserva Natural do Rio Cachoeira, em Antonina, Paraná. O levantamento foi realizado em 187 parcelas permanentes, que representam 23,5 ha amostrados. Foram identificadas 306 espécies distribuídas em 68 famílias. A zoocoria foi a síndrome de dispersão mais comum (81,7% das espécies). Espécies tolerantes à sombra superaram discretamente as não tolerantes (50,3% e 49,7%, respectivamente). Espécies de distribuição geográfica ampla representaram quase metade do total (48,4%). Desse conjunto florístico, 21 espécies encontram-se sob alguma categoria de risco de extinção, o que representa 6,9% do universo encontrado, valor maior que o verificado na maioria dos estudos conduzidos nessa mesma formação (em torno de 2%). Essa situação reflete os efeitos da pressão contínua a que a floresta está sujeita, onde a superexplotação de essências nativas ao longo dos anos, associada à deterioração da floresta por meio da fragmentação e da perda de hábitats, resulta em maior risco à conservação de espécies do bioma.Palavras-chave: Floresta Ombrófila Densa; florística; espécies ameaçadas; síndromes de dispersão. AbstractTree species from an Atlantic Forest remnant in Antonina, Paraná, Southern Brazil. Aiming to support new vegetation dynamics and climate change studies, a floristic survey of the tree species was conducted in the Atlantic Forest at Rio Cachoeira Natural Reserve, in Antonina municipality, Southern Brazil. The survey was intensified in 187 permanent plots, representing 23.5 ha of sampled area. The floristic collection was represented by 306 tree species, distributed in 68 families. Zoochory was the most common dispersion syndrome (81.7%). According to the shadow tolerance, 50.3% of the species were tolerant, while non-tolerant species were 49.7%. Wide geographical distribution species represented almost half of all this floristic set (48.4%).Threatened species were 6.9% of all species found (21), a higher value than that one reported to other studies on this forest type (around 2%). This situation shows the effects of continuous pressure on the forest, as the over exploitation of the vegetation through the years, associated to the forest damage by fragmentation and habitat loss process leads to the higher risks for species conservation on this biome.Keywords: Ombrophilous Dense Forest; floristic composition; threatened species; dispersion ways.

Abstract Studies that address the floristic composition of the Atlantic forest show that Myrtaceae is one of the richest families in number of tree species. In Southern Brazil, Myrtaceae is present mainly in forest formations, such as broadleaf rain forests and broadleaf cloud forests, mixed needle and broadleaf forests (Araucaria forests), and seasonal semi-deciduous forests. The objective of this study was to survey the Myrtaceae of the upper highlands of São Joaquim National Park, to contribute with the knowledge of its flora. Eight genera and 16 species of Myrtaceae were found: Acca sellowiana, Blepharocalyx salicifolius, Eugenia handroi, Myrceugenia (8 spp.): M. acutata, M. alpigena, M. euosma, M. miersiana, M. myrcioides, M. oxysepala, M. pilotantha, and M. regnelliana, Myrcia (2 spp.): M. aethusa and M. hartwegiana, Myrrhinium atropurpureum, Psidium salutare, and Siphoneugena reitzii. Descriptions, illustrations, an identification key and commentaries are presented. Other studies about Myrtaceae in highland areas of Southern Brazil present Myrceugenia as the richest genus in species, while other mentioned genera were not registered in SJNP upper highlands. The family’s richness patterns and diversity in a local and regional scale should be better investigated in the Atlantic Forest.

Habitat loss is one of the main consequences of landscape transformation by humans. Monitoring biodiversity changes in areas under different management strategies is fundamental for species conservation. Our study is the first to assess the role of forest disturbance history on spider (Araneae) biodiversity in the westernmost portion of the Atlantic Forest. We analyzed taxonomic and functional aspects of spider assemblages in understories in a large forest fragment in southwestern Brazil. Spiders were sampled in five 30 m × 5 m plots over three seasons in three areas with different management histories: clear-cutting, selective logging, or native plots. We also characterized tree basal area, tree density, and canopy openness. The clear-cut plots showed more canopy openness and low habitat heterogeneity due to the high density of one pioneer native tree species. Forest structure in selective logging and native plots was similar. Spider richness, abundance, and functional richness were affected only by the season. Species composition also differed among the areas depending on the season. The abundance of web-building species was mainly associated with clear-cut areas in winter and spring. These results highlight the importance of natural regeneration in the Atlantic Forest after disturbance for the conservation of regional spider biodiversity.

We compared the composition and guild structure of bird communities of riparian and upland forest in an Atlantic forest reserve, the Godoy State Park (GP), in northern Paraná State, southern Brazil. Unlimited distance point counts were sampled monthly from September-December 2001, along four trails. Two trails in upland forest (TA and TB) were parallel to each other and about 300 m apart. Two trails in riparian forest (TC and TD) were along the Apertados River, about 100 m away from the river. A total of 145 species were recorded: 81 species were recorded in both upland and riparian forests, 19 species were recorded only in upland forest and 45 species were recorded exclusively in riparian forest. Among the 81 species occurring in both forest types, 18 species had significantly higher numbers of contacts in the riparian forest while only 8 species had significantly higher numbers of contacts in the upland forest. Taking into account the contacts numbers of the species the large frugivores guild was closely associated to the upland forest, while bamboo and vine-tangles insectivore, canopy insectivores, edge omnivores, ground omnivore and midstory insectivores were those more closely related to the riparian forest.

Previously known from two specimens, Kaempfer's Tody-tyrant Hemitriccus kaempferi is a globally threatened species endemic to the southern Brazil Atlantic Forest. The first field observations of this little-known taxon were made in the 1990s and our data therefore provide the first published information on its natural history, including breeding biology, behaviour and vocalizations, as well as a new locality. As very little information has appeared in the literature concerning the identification of this species, we present notes on its plumage and habits. Remarks concerning the species's conservation prospects and the importance of the remaining forest in the vicinity of the type-locality for other threatened bird species are made.

The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosys tems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for the first time, a survey of the bird species and their conservation status for the different habitats present on the island. We recorded 269 bird species of 54 families (25 species were seabirds). More than 50% (140) of the total number of species were residents or probable residents, 20% (58) were visitors and a relatively high number of species (61, 23%) had indeterminate residential status. Nearly 15% (35 species) of the 244 landbird species observed were endemic to the Atlantic Forest. Habitat specificity was recorded for 40% (97 species). We recorded one Endangered (Solitary Tinamou Tinamus solitarius), one Vulnerable (White-necked Hawk Leucopternis lacernulata), and three Near-threatened species (Azure Jay Cyanocorax caeruleus, Azure-shouldered Tanager Thraupis cyanoptera, Black-backed Tanager Tangara peruviana). We also recorded six locally threatened species that we predict will become extinct in the near future. The future for the birds of the island is uncertain, especially for habitat specialists, due to habitat loss for resort developments, and a lack of concern by the government and local people.

Invasive Tree Species

AbstractThe Atlantic Forest is one of the largest and most biodiverse rainforests of South America but anthropogenic activities are drastically changing these landscapes. The invasion of alien or exotic species is one of the greatest threats to biodiversity. There are few studies of invasive species in tropical Brazilian ecosystems. This research examines growth and ecological aspects of Syzygium cumini and Clitoria fairchildiana, two invasive tree species in the Pedra Branca State Park, an Atlantic Forest remnant in southeastern Brazil. Both species were successfully dated, indicating an average age of 58 and 31 years, respectively. A positive relationship between growth and precipitation of the previous growing season suggests an ecological adaptive strategy, which could be facilitating their invasion into the environment. Cumulative growth diameter curves indicate slow and fast growth rates for S. cumini and C. fairchildiana, respectively. Growth release episodes detected in the tree rings indicate increased anthropogenic disturbances over the last 50 years.
