This study presents an inventory of the bird fauna of the Mata do Junco State Wildlife Refuge in Capela, in the northeastern Brazilian state of Sergipe. Monthly samples were collected between January 2011 and May 2012. Each 3-day sample was based on mist-netting (100 m) in two areas and the compilation of MacKinnon lists of 10 species. During the 17 months of the study period, the occurrence of 129 bird species belonging to 41 families was confirmed for the study area. In the mist-nets, a total of 469 individuals representing 58 species were captured in 3400 net-hours of sampling effort. A total of 100 MacKinnon lists were compiled, resulting in an inventory of 119 bird species. Eight of the species are endemic to Brazil, of which, five are restricted to the Brazilian Atlantic Forest. Three of the species are included in the IUCN Red List, at different levels of concern. Overall, the results of the study indicate that the Mata do Junco represents an important area for the protection of the region’s avian fauna and the habitats they rely on.

The new species Ouratea cauliflorais described, illustrated, and comments on its ecology, geographical distribution, and conservation status are provided. This species is morphologically similar to O. verticillata, but can be easily distinguished by its white flowers and the inflorescences cauliflorous or emerging from short and patent branches on the stem. The new species is endemic to a single locality in the central region of Espírito Santo, in the Brazilian Atlantic Forest, and according to the criteria of the IUCN Red List of endangered plant species, it is regarded as “vulnerable”.

Per Se

The IUCN Red List is an important conservation tool. Although its criteria are used worldwide, in most cases the classification process per se is restricted to a group of experts with restricted or no participation of the general public. This may raise concerns from final Red List users, which, without knowing the data or procedures adopted by the experts, may argue on the outcomes, final classification adopted, or the overall use of the lists. IUCN recommends that all assessments must be backed up by data and justifications, making them as accurate and transparent as possible. We describe here the assessment of Eptesicus taddeii, a bat species endemic to the southern Atlantic Forest of Brazil, indicating how and why the species was flagged as Vulnerable - B2ab(i, ii, iii) during its national evaluation.

The new species Prepusa dibotrya from the Brazilian Atlantic Forest in Espírito Santo is described and illustrated, with comments on its ecology, geographical distribution, and conservation status. The new species is similar to P. viridiflora and must be considered “critically endangered” in accordance with the criteria of the IUCN Red List of endangered plant species.

Abstract We present the first voucher-based record of Pouteria macrocarpa for Brazilian Atlantic forest and extend the occurrence area of it. Besides, a brief taxonomic description, an identification key for lignified-fruits Pouteria species, and information about phenology and herbarium records are provided. According to the IUCN Red List and the Red Book of the Brazilian Flora, the species is considered Vulnerable (VU). However, facing the new available data, we believe it should be reassessed as Endangered (EN).

Two new species of Eugenia (Myrtaceae), endemic to the Atlantic forest in the state of Espírito Santo, Brazil, are described. Eugenia amorimii has fruits with brown mealy indumentum and is similar to E. multicostata, while Eugenia sobraliana has a characteristic pedicels exfoliating longitudinally after anthesis and is similar to E. sessiliflora. The new species are restricted to single localities in the central and northwestern regions of Espírito Santo. According to the criteria of the IUCN Red List of endangered plant species both species should be considered as “Vulnerable”.

AbstractThe present study reports associations between feather mites (Astigmata) and birds in an Atlantic Forest fragment in Rio Grande do Norte state, in Brazil. In the laboratory, mites were collected through visual examination of freshly killed birds. Overall, 172 individuals from 38 bird species were examined, between October 2011 and July 2012. The prevalence of feather mites was 80.8%, corresponding to 139 infested individuals distributed into 30 species and 15 families of hosts. Fifteen feather mite taxa could be identified to the species level, sixteen to the genus level and three to the subfamily level, distributed into the families Analgidae, Proctophyllodidae, Psoroptoididae, Pteronyssidae, Xolalgidae, Trouessartiidae, Falculiferidae and Gabuciniidae. Hitherto unknown associations between feather mites and birds were recorded for eleven taxa identified to the species level, and nine taxa were recorded for the first time in Brazil. The number of new geographic records, as well as the hitherto unknown mite-host associations, supports the high estimates of diversity for feather mites of Brazil and show the need for research to increase knowledge of plumicole mites in the Neotropical region.

Ombrophilous Forest

The Pernambuco Center of Endemism (PCE) in northeastern Brazil is highly fragmented and degraded. Despite its potential conservation importance the bird fauna in this area is still relatively unknown and there are many remnant fragments that have not been systematically surveyed. Here, we report the results of bird surveys in five forest fragments (one pioneer, two ombrophilous and two seasonal). In total, 162 taxa were recorded, 12 of which are endemic to the PCE. The frequency of endangered species was lower than what has been reported in studies from the same area and most of the taxa considered to be at risk of extinction were sub-species of uncertain taxonomic validity. The comparatively low number of endemic/threatened species may be due to the small size of the fragments in the present study - a consequence of the high levels of habitat loss in this region. Analysis of species richness patterns indicates that ombrophilous forest fragments are acting as refuges for those bird species that are most sensitive to environmental degradation.

Population decline is a process, yet estimates of current extinction rates often consider just the final step of that process by counting numbers of species lost in historical times. This neglects the increased extinction risk that affects a large proportion of species, and consequently underestimates the effective extinction rate. Here, we model observed trajectories through IUCN Red List extinction risk categories for all bird species globally over 28 years, and estimate an overall effective extinction rate of 2.17 × 10 −4 /species/year. This is six times higher than the rate of outright extinction since 1500, as a consequence of the large number of species whose status is deteriorating. We very conservatively estimate that global conservation efforts have reduced the effective extinction rate by 40%, but mostly through preventing critically endangered species from going extinct rather than by preventing species at low risk from moving into higher-risk categories. Our findings suggest that extinction risk in birds is accumulating much more than previously appreciated, but would be even greater without conservation efforts.
