“…10,no. 1 Introdução A destruição das florestas do sul do Brasil ocorreu de forma bastante acentuada ao longo dos anos, inicialmente pelo extrativismo madeireiro e posteriormente por atividades agropastoris, que somadas à expansão urbana, resultaram num cenário lastimável (Maack 1981, Pichorim & Bóçon 1996, Anjos 1998, Bornschein & Reinert 2000. Atualmente o pouco que resta da vegetação original no Paraná encontra-se bastante fragmentada, formando pequenas ilhas isoladas que não perfazem mais de 4% da área total do estado (Fundação SOS Mata Atlântica 1992).…”

Abstract:In this study the community of birds in a small size remnant (10 ha) of Araucária forest, located in the city of Tijucas do Sul, Paraná was evaluated. During the period of November, 1999 to April 2001, 15 surveys had been carried, in which capture with mist nets and visual and aural contacts were used to estimate avian abundance and richness. We recorded 118 species of 35 families. According to the frequency of occurrence around 44% of species were considered with low frequency. When analyzed the trophics guilds, omnivorous and insectivorous of foliage were the most representative. By the capture method had been gotten 501 captures of 47 species. The capture species had relative abundances varying from 0.31 to 13.16% and the uniformity index was 0.83, demonstrating that the avian assemblage had a low dominance of some species. The structure of avian assemblage registered is expected for a small size remnant, with high relative abundance of generalists species and guilds, and the presence of a high number of species with low frequency of occurrence. Despite of, the specific composition presents a great number of species forest dependents showing that this forest remnant has a important role in the maintenance of species regionally.

“…No Paraná, Bornschein & Reinert (2000) supõem que essa espécie originalmente habitasse os ambientes ciliares, os quais são regularmente rejuvenescidos pela dinâmica dos rios, e que posteriormente se difundiu nas bordas das florestas de outras áreas do estado, em virtude das modificações ambientais de origem antrópica.…”

Thamnophilus doliatus (choca-barrada) tem ampla distribuição na região neotropical, do México até a Argentina. No Brasil essa espécie ocorre em todas as regiões; no Sul era conhecida apenas no estado do Paraná. O primeiro registro da espécie em Santa Catarina foi realizado por meio de documentação com fotos, gravação de sua vocalização e vídeo de um espécime macho. O indivíduo foi encontrado em um pequeno fragmento florestal às margens de um lago artificial formado pelo Rio Chapecó, no município de Ipuaçu, região oeste do estado. Possivelmente essa espécie está expandindo sua distribuição, como observado em outras localidades.

Assessing the conservation status of a species is important for designing effective conservation measures. Consequently, it is often vital to review it to update biodiversity management.Formicivora acutirostrisis a bird from coastal marshes and related habitats of Brazil’s southern flood plains. It is considered endangered in Brazil but near threatened globally. In 2007, its area of occupancy (AOO) and population size were estimated based on assessment of aerial photographs from 1978 and 1980. Since the species is threatened and occupies a small area scattered across a coastal pressured region, we aimed to reassess its conservation status and assess its Green Status. We compiled new records, conducted new density estimates, and compared the previous mapping with orbital imagery to estimate the current AOO, habitat loss, population size, and review its conservation status based on the International Union for Conservation of Nature criteria. The species is distributed across 10 populations, including two new populations from the southern coast of Santa Catarina to the northern coast of Rio Grande do Sul. We estimated the AOO at 4,102 ha and the population as 6,284 mature territorial individuals. The previously mapped AOO has decreased by 1,535 ha due to ecological succession. The loss of habitat due to invasion by exotic grasses is the main anthropogenic impact. We recommend that the species be considered vulnerable. The Green Status indicates that the Conservation Legacy of actions taken thus far and the Conservation Dependence of ongoing actions are null, but it highlights the importance of future actions for species conservation. We propose the establishment of exotic-free zones as small geographic areas with a significant amount of minimally invaded environments, which we suggest as priority areas for the conservation of the species due to their cost-effective management potential. We also propose assisted colonization to enhance its long-term conservation.
