Bird communities in three forest types in the Pernambuco Centre of Endemism, Alagoas, Brazil Iheringia, Sér. Zool.
Lobo-Araújo,Lahert W.; Toledo,Mário T. F.; Efe,Márcio A.; Malhado,Ana C. M.; Vital,Marcos V. C.; Toledo-Lima,Guilherme S.; Macario,Phoeve; Santos,Jhonatan G. dos; Ladle,Richard J..
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...

Sexual dimorphism in Amphisbaena nigricauda (Reptilia, Squamata, Amphisbaenidae) from Southeastern Brazil Iheringia, Sér. Zool.
Souza e Lima,Francco A. N. de; Gasparini,João Luiz; Almeida,Antonio de Padua; Vital,Marcos V. C.; Mott,Tamí.
Amphisbaena nigricauda Gans, 1966 is a small, poorly known amphisbaenid endemic to the restinga of the states of Espírito Santo and Bahia, Brazil. We analyze 178 specimens collected in Vitória municipality, state of Espírito Santo, Brazil, to investigate whether this species show sexual dimorphism in pre-cloacal pores and in morphological characters. Sex was determined by a ventral incision and direct inspection of gonads. A PCA analysis was performed to generate a general body size measurement. A T test and the non-parametric Mann-Whitney test were used to assess whether this species show sexual dimorphism on five morphometric and five meristic characters, respectively. Sex could not be determined in 36 specimens because they were mutilated in the...
