| 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, which, coupled with their known restricted distribution, could help access their conservation status and contribute to the study of the Brazilian biodiversity. We sequenced 88 individuals for plastid intergenic spacers and genotyped 186 individuals for five microsatellite loci. Compared among each other, C. sendtneriana and C. serrulata presented the highest values of genetic diversity [π% (sd) = 0.23... |

| Aim Environmental DNA metabarcoding has recently emerged as a non‐invasive tool for aquatic biodiversity inventories, frequently surpassing traditional methods for detecting a wide range of taxa in most habitats. The major limitation currently impairing the large‐scale application of eDNA‐based inventories is the lack of species sequences available in public genetic databases. Unfortunately, these gaps are still unknown spatially and taxonomically, hindering targeted future sequencing efforts. Innovation We propose GAPeDNA, a user‐friendly web interface that provides a global overview of genetic database completeness for a given taxon across space and conservation status. As an application, we synthetized data from regional checklists for marine and... |

| To control illegal wildlife-product trade and protect endangered species of animals, unambiguous identification of the captured specimens is essential. Forensic genetic tools have contributed to identify animal species for conservation purposes promoting accurate results for informing public policies and management of the biodiversity. The southern muriqui (Brachyteles arachnoides) is the largest non-human primate of the Neotropical region and is critically endangered (IUCN Red List of Threatened Species), mainly due to the illegal hunting for bushmeat. In this study, we describe a molecular method using PCR/RFLP to differentiate between bushmeat of southern muriqui and the meat of the domestic animals most commonly consumed in Brazil (Bos taurus, Ovis... |

| A Red List assessment is insufficient to determine priorities for ex situ conservation in large genera such as Rhododendron, where there may be hundreds of taxa in any one Red List category. We have utilised an analysis of the geographic origins of 1?215 taxa of Rhododendron (Ericaceae) as a method to prioritise Red List taxa for ex situ conservation. This analysis includes descriptions of distribution and endemism by country of origin, analysis of the incidence of the 715 Red List taxa by country of origin, and determination of the extent to which taxa from each country of origin are in cultivation. We determined that of 30 countries of origin and a ‘Europe’ aggregate, 24 origins contain Red List taxa. Of those 24 origins, 17 origins and ‘Europe’ have... |

| Although Rhododendron subg. Vireya, comprising 400 taxa, is one of the largest plant genera in Southeast Asia, with taxa found throughout the region, it has a significant conservation problem, with conservation status assessments in 2011 and 2015 placing 201 taxa in an IUCN Red List threat category. Plant conservation is driven by the Global Strategy for Plant Conservation, with Target 8 requiring 75 % of threatened plant taxa to be conserved in ex situ collections, by 2020. To date there has been limited analysis of conservation priorities for subg. Vireya, or any consideration of how its geographic characteristics, complex taxonomy, and existing ex situ collections might influence priorities. We analyse the IUCN Red List status of geographic origins and... |

| ABSTRACT The present report represents the first cytogenetic description of Steindachneridion doceanum, great catfish which is currently at high extinction risk and it is listed as threatened on the red list of the Brazilian Ministry of the Environment, also are suggested karyotype relationships with other species of the same genus endemic from other river basins. The results revealed a diploid number of 2n = 56 and the karyotype composed of 18 metacentric, 20 submetacentric, 10 subtelocentric and 8 acrocentric chromosomes (NF = 104). The AgNORs and CMA3 signals were coincident in location occupying the short arm of an acrocentric chromosome pair (25th), in a secondary constriction. The 5S rDNA genes were localized on the short arms of one subtelocentric... |

| The Rufous-nosed Mouse Wilfredomys oenax is a rare Sigmodontinae rodent known from scarce records from northern Uruguay and south and southeastern Brazil. This species is underrepresented in scientific collections and is currently classified as threathened, being considered extinct at Curitiba, Paraná, the only confirmed locality of the species at southeastern Brazil. Although specimens from São Paulo were already reported, the presence of this species in this state seems to have passed unnoticed in recent literature. Through detailed morphological analyzes of specimens cited in literature, the present work confirms and discusses the presence of this species in São Paulo state from a specimen collected more than 70 years ago. Recently, by the use of modern... |

| ABSTRACT The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order to characterize the community of mammals of this region, considering species richness, we installed 80 camera-trap stations. With a sampling effort of 10,370 camera-days we recorded 28 species (22 wild and six domestic). Opportunistically, we recorded four mammals, resulting in a total richness of 32 species, five of which are included in the global list of endangered species, and seven in the national... |

| Abstract Coastal lagoons and their surrounding habitats often harbour high biodiversity and some of the most threatened ecosystems in the world. However, in the Neotropics the biodiversity is often poorly described, lacking even inventories of species which therefore limits the assessment of threats and the stablishment of efficient conservation measures. We present here lists of bird species recorded at ten sites along the under-studied coastal lagoons of southern Santa Catarina, Brazil, collected mainly from October 2012 to March 2018. We present quantitative data for endemic and threatened species, identify migratory status and highlight distributional novelties. In total, we recorded 229 species encompassing 63 families, including twelve species of... |

| A floristic and structural survey of a natural grassland community was conducted on Morro do Osso, a granitic hill in Porto Alegre, RS, Brazil. Structural data were surveyed in 39 one square meter plots placed over two major grassland areas. An accidental fire has occurred in one of the areas approximately one year prior to our survey, leading to further analysis of parameters differences between sites. The floristic list contains 282 species, whereas the structural survey has found 161 species. Families with highest accumulated importance values were Poaceae, Asteraceae and Fabaceae. The diversity and evenness indexes were 4.51 nats ind-1 and 0.86, respectively. Cluster analysis denoted two groups coinciding with the areas distinguished by the fire... |

| Lagoa Santa, a small town in southeastern Brazil where naturalist Peter Lund lived, is regarded nowadays as an important historical site for the biological sciences. From 1847 to 1855, J.T. Reinhardt, hosted by Lund, collected 343 bird species. This material is an outstanding reference for many modern ornithological studies. The present paper reports the occurrence of some rare and threatened birds for the region of Lagoa Santa between 1998 and 2005. In this account I list the Rusty-margined Guan Penelope superciliaris Temminck, 1815; the Roseate Spoonbill Platalea ajaja Linnaeus, 1758; the Maguari Stork Ciconia maguari (Gmelin, 1789); the Wood Stork Mycteria americana Linnaeus, 1758; the Black Hawk-eagle Spizaetus tyrannus (Wied, 1820) and the... |

| The pampas deer, Ozotoceros bezoarticus (Linnaeus, 1758) was studied between August 1996 and September 1997 at Fazenda Santa Maria (25º34' and 25º36'S, 49º46'and 49º49'W) at Lapa, Paraná State. During that period we have collected information on feeding habits, group composition, time of the year for birth of youngsters and time for antlers change. The presence of the animal in the area was confirmed by the finding of vestiges and visual occurrences. Animais were observed feeding on young leaves of soya been (Glicine max), oat (Avenasaliva), ryegrass (Lolium mulliflorum) and barley (Hordeum vulgare). Only one female was observed feeding on dry leaves. A stag was observed feeding on a barley ear. Group's average size was 1.5 individual. Stags/female... |
