Speothos Venaticus

AbstractThe bush dog Speothos venaticus, a rarely seen Neotropical canid categorized as Near Threatened globally, is categorized as Vulnerable in Brazil. In the Atlantic Forest occurrence data of this species are extremely rare. Here we document new records of the bush dog in four reserves in a large remnant of continuous coastal Atlantic Forest in Paraná state, southern Brazil. From a total of 4,112 trap days in two camera-trap surveys in 2009 and 2011 we obtained one opportunistic sighting and three independent photographic records of the bush dog. Additionally, park guards reported previous sightings (>4 years earlier) in three of these reserves, including the reserve where we did not record the species. Our results indicate that the remnant coastal Atlantic Forest of Paraná state is an important region for the conservation of the bush dog in southern Brazil. Given the rarity of this species in its natural habitat we suggest that conservation efforts in this region should focus on minimizing the potential threats (prey depletion from poaching and disease transmission from domestic dog) to the species.

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within the Pampa and Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions in this state, in 2002 and 2019, across 19 municipalities. Here, we provide new records for 19 species, of which 13 are recorded for the first time from the state, five have their distributions expanded, and one is recorded again from a same locality previously reported in the literature. Furthermore, 13 species were collected for the first time in the Pampa biome and one in the Atlantic Forest.

Speothos Venaticus

The diet and habitat associations of bush dogs Speothos venaticus, categorized as Vulnerable on the IUCN Red List, are virtually unknown in the wild. In eastern Paraguay, bush dogs occur in the Reserva Natural del Bosque Mbaracayú. The Reserve contains one of the largest remaining fragments of the Interior Atlantic Forest in Paraguay as well as cerrado and grassland habitats. We analysed bush dog faeces to determine their diet. Bush dogs in the Reserve mostly ate vertebrates. Although small mammals (marsupials and rodents) were the most numerically dominant foods, agoutis Dasyprocta azarae and pacas Cuniculus paca represented 90.5% of biomass consumed. Cecropia fruit was also present in the diet. This is the first documentation of fruit consumption by bush dogs. Signs of bush dogs were detected in all habitats, with the greatest proportion in high forest.

Occurrence Records

Abstract We report six new occurrence records of the bush dog Speothos venaticus, a widely distributed South American carnivore that is threatened with extinction. These records are accompanied by notes on the places where the records were made, such as vegetation type, date and information about the protection of areas. The records, obtained over the last 17 years in Paraná state, southern Brazil, offer an improved understanding of the species geographic range and the threats it faces and can enable better assessments of the conservation status of the species in southern Brazil.

Speothos Venaticus

The bush dog (Speothos venaticus, 2n = 74) is a near threatened species taxonomically classified among South American canids. We revised the bush dog karyotype and performed a comparative sequence analysis of satellite and satellite-like DNAs in 6 canids: the bush dog, domestic dog (Canis familiaris, 2n = 78), grey wolf (C. lupus, 2n = 78), Chinese raccoon dog (Nyctereutes procyonoides procyonoides, 2n = 54+B), red fox (Vulpes vulpes, 2n = 34+B), and arctic fox (V. lagopus, 2n = 48-50) to specify the species position among Canidae. Using FISH with painting and BAC probes, we found that the distribution of canid evolutionarily conserved chromosome segments in the bush dog karyotype is similar to that of the domestic dog and grey wolf. The bush dog karyotype differs by 2 acrocentric chromosome pairs formed by tandem fusions of the canine (29;34) and (26;35) orthologues. An interstitial signal of the telomeric probe was observed in the (26;35) fusion site in the bush dog indicating a recent evolutionary origin of this rearrangement. Sequences and hybridisation patterns of satellite DNAs were compared, and a phylogenetic tree of the 6 canid species was constructed which confirmed the bush dog position close to the wolf-like canids, and apart from the raccoon dog and foxes.

Speothos Venaticus

AbstractThe bush dog Speothos venaticus, a rare Near Threatened South American canid that lives in packs, was thought to be extinct in Minas Gerais state, south-eastern Brazil, until recently. Here, we report four recent records of the species in Minas Gerais, the first in the state since the description of the species in 1842. All records are from the Cerrado ecosystem in the north and north-west of the state; two are from animals found dead, one from footprints and another from a camera trap. Three of the records were inside or close (< 10 km) to strict protected areas, in a region recognized as the Protected Areas Mosaic Sertão Veredas–Peruaçu, where we expect any new records of the bush dog to be found. We discuss the low probability of detecting the bush dog and the main regional threats to the species, and emphasize the need to protect large and interconnected natural areas and keep them free of domestic dogs to avoid the extinction of the bush dog in Minas Gerais.
