We report on seven new localities for Mantella bernhardi, a Malagasy poison frog that was previously known only from a single site. This species has been considered threatened with extinction because of ongoing habitat destruction and collection for the pet trade (up to c. 3,000 specimens per year). The new localities considerably extend the known range of this species, which has now been documented from c. 21.00° to 24.15°S and 47.00° to 48.00°E, and over 60–629 m altitude. Two of the sites are within protected areas (Ranomafana National Park and Manombo Special Reserve). An overlap analysis of the potential distribution area of the species, based on the extent of remaining primary vegetation, indicates that the habitat of M. bernhardi in south-eastern Madagascar is fragmented and populations may be relatively small and isolated. We support the IUCN Red List category of Endangered for this species and highlight the need for detailed studies of its populations.

Background: Tropical lowland rainforests are threatened by deforestation and degradation worldwide. Relatively little research has investigated the degradation of the forests of South-east Asia and its impact on biodiversity, and even less research has focused on the important peat swamp forests of Indonesia, which experienced major losses through severe fires in 2015. Methods: We acoustically sampled the avifauna of the Berbak National Park in 2013 in 12 plots split in three habitats: primary swamp forest, secondary swamp forest, and shrub swamp, respectively representing non-degraded, previously selectively logged, and burned habitats. We analysed the species richness, abundance, vocalisation activity, and community composition across acoustic counts, plots, feeding guilds and IUCN Red List categories. We also analysed community-weighted means of body mass, wing length, and distribution area. Results: The avifauna in the three habitats was remarkably similar in richness, abundance and vocalisation activity, and communities mainly differed due to a lower prevalence of understory insectivores (Old-World Babblers, Timaliidae) in shrub swamp. However primary forest retained twice as many conservation-worthy species as shrub swamp, which harboured heavier, probably more mobile species, with larger distributions than those of forest habitats. Conclusions: The National Park overall harboured higher bird abundances than nearby lowland rainforests. Protecting the remaining peat swamp forest in this little-known National Park should be a high conservation priority in the light of the current threats coming from wildlife trade, illegal logging, land use conversion, and man-made fires.

SummarySerra da Capivara National Park covers an area of about 1,300 km2 in south-eastern Piauí, north-eastern Brazil. The park's vegetation is the endemic caatinga, with a few remnants of semi-deciduous forest in some canyons. The area has a reasonable diversity of plants, with 615 catalogued species. Since 1986, 208 bird species have been observed in the park and its buffer zone, including 10 threatened or near-threatened species, plus two recently extinct in the area. Other species are regionally rare and have declined over parts of their distribution. The park also harbours several threatened mammals and caatinga endemics. Despite having been created in 1979 the park remains effectively unprotected and unmanaged. Current levels of poaching and habitat destruction prejudice the future of several species, including some that have already vanished from other parts of the caatinga.O Parque Nacional da Serra da Capivara abrange uma área de aproxidamamente 1,300 km2 no sudeste do Piauí, nordeste do Brasil. A vegetação do parque é a caatinga, com alguns enclaves de mata semi-decíua. A área possui uma razoável diversidade de plantas, com um total de 615 espécies já catalogadas. Desde 1986, um total de 208 espécies de aves foram observadas no parque e sua zona-tampão, incluindo 10 consideradas ameaçadas ou quase-ameaçadas, além de duas recentemente extintas na área. Outras espécies são regionalmente raras ou tern declinado em parte de sua área de distribuição. O parque também abriga diversos mamíferos ameaçados, e endemismos da caatinga. Apesar de ter sido criado em 1979, o parque ainda não foi consolidado e é pouco mais que um parque de papel. Com os presentes niveis de caça clandestina e destruição de habitats, diversas espécies se extinguirão, incluindo algumas já desapareddas de outras partes da caatinga.

AbstractThe distribution and variability of the subspecies of Panorpa germanica in south-eastern Europe are shown. The type-specimens of P. gibberosa MeLachlan, 1869 and P. titschacki Esben-Petersen, 1934, which must be regarded as subspecies of germanica, were re-examined and are described. P. germanica titschacki is distributed in southern Yugoslavia and central northern Greece. P. germanica graeca Lauterbach is not as widespread as Lauterbach (1972) suggested as some of his types belong to titschacki. P. germanica is still unknown from the Peloponnesus, ♀♀ mentioned from there by Willmann (1974) are P. lacedaemonia. Contradicting Bartos (1965) P. cognata is not known from Albania since the specimens determined by him as cognata belong to germanica. The relationships between several subspecies of P. germanica are discussed. New records of the allied P. lacedaemonia are added and used to indicate the distribution area of this species.

AbstractLonchophylla bokermanni is a nectar-feeding bat endemic to south-east Brazil that is currently categorized as Vulnerable in Brazil but as Data Deficient on the IUCN Red List. Originally described in the Cerrado savannah of Minas Gerais state in 1978, the species is known to occur in only two other nearby localities. In the last 2 decades individuals identified as L. bokermanni were recorded in the Brazilian Atlantic Forest, increasing the known range of the species. A recent taxonomic review, however, has shown that Atlantic Forest individuals belong to a separate, new species, Lonchophylla peracchii. L. bokermanni, therefore, is known from only three localities, with an Extent of Occurrence of 1,506 km2. Because this EOO is < 5,000 km2, the species is known from <5 localities, and there is a presumed continued decline in its habitat extent and quality, it should be categorized as Endangered on the IUCN Red List. We recommend that the state of the three known populations of L. bokermanni be evaluated, and that surveys for further populations are required, particularly in Serra do Cipó National Park.

The present paper provides new records of <em>Protostropharia alcis </em>in Poland. So far this species was known in the country only from several latest localities in the Biebrza National Park (Biebrza Basin) and the Kampinos National Park (Warsaw Basin). The new localities are situated in the Wigierski National Park (the East Sudetian Lake District) and in the north-western slope of Mt Wierzejska (the Holy Cross Mountains), where <em>P. alcis </em>was collected on dung of herbivores (eurasian elk and red dear) within several types of forest communities. All specimens of <em>P. alcis </em>were collected in recent years, from late September to early October, in the period 2012-2013. A full description and illustration of <em>P. alcis </em>based on gathered collections are given. Its delimitation, the knowledge of its ecology, general distribution, and threat is also briefly discussed. Based on the new and known distribution data for <em>P. alcis </em>in Poland, its red list category is proposed.

The turtle fauna of Asia is one of the most diverse in terms of number of species, but is also the most endangered. This is a result of human activities such as habitat destruction and over-harvesting for the pet, food, and medicine trades (van Dijk et al., 2000). Effective conservation measures require adequate baseline data on the ecology, systematics, and geographic distribution of each species. Unfortunately, Asian turtle research is difficult because of the longstanding, high-volume Asian turtle trade that includes long-distance transport. Not only are wild turtles increasingly difficult to find, those found in the field may have escaped or been released into the wild. In particular, because of the turtle trade, reconstructing the natural distributions of turtles becomes a problem; turtle records from Asia need to be treated with caution. A specific example of this situation was pointed out by Parham & Li (1999), where some records from the pet trade proved to be misleading.
