1. ASSESSMENT OF GIS-ASSISTED MOVEMENT PATCHES USING LCP FOR LOCAL SPECIES: NORTH CENTRAL ANATOLIA REGION, TURKEY
ABSTRACT As a result of the fragmentation and degradation of forests, the connectivity of natural habitats has been decreasing. Thus, problems in gene flow in wildlife have begun to arise. The connection of landscape patches with corridors is now an important subject of landscape planning. Central Anatolia has been affected by forest fragmentation due to its

2. Habitat structure and their influence in lizard’s presence
Abstract Many species are declining due to environmental and physical changes in their habitats. Such disturbs alter the availability of micro-habitats and influences the presence of lizards, being even worse for threatened and endemic species. Glaucomastix littoralis is a teiid species restricted to four restingas areas of Brazil. The understanding about th

3. Use of microhabitats affects butterfly assemblages in a rural landscape
Abstract Landscapes composed of small rural properties may support highly heterogeneous habitat, because they often cover distinct types of land uses adjacent to surrounding forest fragments. Many butterfly species may benefit from this kind of landscape, as very distinct microhabitats can be found in a very restricted spatial scale. To better understand how

4. An overview of the 2017 report of the French academy of Sciences on biodiversity
Abstract: In the present context of concerns for biodiversity, the French Academy of Sciences produced in 2017 a report entitled “Mechanisms of adaptation of biodiversity to climate change and their limits”. We briefly review here the production process and structure of the report, and summarize its conclusions and recommendations. The conclusions emphas

5. Medium and large mammals in a Cerrado fragment in Southeast Goiás, Brazil: inventory and immediate effects of habitat reduction on species richness and composition
Resumo: A fragmentação e a redução de hábitat de vegetação remanescente tem sido as principais ameaças à biodiversidade do Cerrado. Este trabalho teve como objetivo inventariar as espécies de mamíferos de médio e grande porte em um fragmento de Cerrado e avaliar a influência do desmatamento de parte desse fragmento na riqueza e composição de e

6. Genetic diversity and population structure of naturally rare Calibrachoa species with small distribution in southern Brazil
Abstract Calibrachoa is a South-American genus comprising 27 species, several considered endemic or rare; few were subjects in genetic studies. We attempted to generate new data about the phylogenetically related and rare species C. eglandulata, C. sendtneriana, C. serrulata, and C. spathulata concerning their genetic diversity and population structure, whic

7. Genetic diversity in Mexican wild populations of the Great Curassow (Crax rubra)
Abstract The Great Curassow (Crax rubra) is a Neotropical bird with a wide distribution; it is classified under different threat categories and is listed as a vulnerable species by the IUCN. The Official Mexican Standard, the NOM-059-SEMARNAT-2010, indicates that the Great Curassow is a threatened species, and the subspecies Crax rubra griscomi, which is res

8. Activity patterns of frugivorous phyllostomid bats in an urban fragment in southwest Amazonia, Brazil
ABSTRACT: The habitat fragmentation modifies the pattern of animal activity. This study aimed to determine the activity pattern of frugivorous bat species in an urban forest fragment in southwestern Amazonia. The study was conducted from August 2013 to September 2014 with 10 mist nets (9m x 2.5m), opened at ground level throughout all the night and totaling

9. Movement patterns and home range in Diplomystes camposensis (Siluriformes: Diplomystidae), an endemic and threatened species from Chile
ABSTRACT We document movement patterns and home range of Diplomystes camposensis, an endemic and threatened freshwater catfish from Chile. We tracked the movements of seven individuals of different body size (13.5 to 19 cm SL) using portable radio telemetry equipment to investigate movement patterns in relation to day/night activity and habitat use in the Sa

10. Floral and reproductive biology of Alcantarea nahoumii (Bromeliaceae), a vulnerable endemic species of the Atlantic Forest
ABSTRACT Alcantarea nahoumii occurs exclusively in the state of Bahia, Brazil, and is classified as vulnerable due to deforestation and frequent fires in the region. Knowledge of floral and reproductive biology is fundamental to understanding ecological interactions, as well as the reproductive success of plant species. The objective of this study was to eva

11. Diversity and conservation status of Aegla spp. (Anomura, Aeglidae): an update
Abstract The speciose genus Aegla Leach, 1820 is the only valid extant genus of the anomuran family Aeglidae, bearing 83 known species. This diversity may be even greater since there is some evidence for cryptic speciation. The genus is endemic to southern South America, occurring in freshwater habitats. We assessed the conservation status of 82 species of A

12. The use of microsatellite markers in Neotropical studies of wild birds: a literature review
ABSTRACT Despite extensive habitat fragmentation, the Neotropical region possesses 30% of the world´s bird species. Microsatellites have remained one of the most popular genetic markers and have been used in ecological and conservation studies since the 1990’s. We conducted a literature review comparing the number of papers published from January 1990 to
