At least 251 mammal species are recorded for the Brazilan cerrado, which, therefore, is the third richest Brazilian biome. Most mammal surveys in Brazilian cerrado result from studies performed opportunistically and in short time periods. The aims of the present study were (1) provide a checklist for the mammalian fauna based on a five-year sampling in Serra do Facão region, Southeastern Goiás state; (2) compare small non-flying mammals diversity in open and forest areas and (3) compare species diversity before and after the flood caused by a hydroelectric reservoir filling. The data was gathered in 19 sampling periods, from May 2008 to September 2013. We sampled open and forest habitats and captured non-flying small mammals with Sherman and Tomahawk live traps and pitfalls; bats were sampled with mist-nets; large mammals were recorded with camera traps, and by direct observations and track surveys in field. We found 20 species of small non-flying mammals, 10 species of bats and 33 species of larger mammals. Species diversity was greater for forest than open habitats, and was also greater before than after the complete reservoir filling. About 10% of the recorded species are included in the Brazilian official list of threatened species. The total richness represents 25% of all cerrado mammal fauna, highlighting the importance of this area for regional mammal fauna conservation.

The Impact

Abstract Studies of tropical mammal defaunation highlight the loss of species as well as their reduction in abundance and diversity; however, there is a complex series of effects associated with this anthropogenic disruption, including increases in the relative abundance of disturbance-tolerant mammals and the arrival of alien mammals whose effects on biotic interactions have been poorly studied. We compared the species richness, composition, interaction strength, and patterns of daily activity of mammals that consume the fruits of Pouteria sapota on the forest floor, both inside and outside of the Los Tuxtlas Field Station (LTFS) in Veracruz, southern Mexico. Using camera traps, we recorded eight mammal species interacting with the fruits inside the LTFS ( trees) and nine species interacting outside ( trees). Alien species such as Canis lupus familiaris were recorded both inside and outside of the LTFS, whereas Bos taurus was only recorded outside. Medium-sized generalist mammals were overrepresented both inside and outside of the LTFS, evidencing an impoverishment of the fauna, when compared to the mammal assemblage reported to interact with P. sapota fruits in a more intact forest. The daily activity patterns of the mammals that interacted strongly with P. sapota fruits were different inside and outside the LTFS, particularly in the case of Cuniculus paca. Our results show that the impact of human activity is highly pervasive, directly affecting the mammalian fauna at different levels and indirectly affecting the biotic interactions in which these animals are involved.

The state of Tocantins is located in Central Brazil. The northern extreme of this state corresponds to the southeastern portion of the Amazon biome, while it is covered primarily by Cerrado savanna, as well as the transition area between these two biomes. We provide a checklist of large- and medium-bodied mammals from four localities in Tocantins, update the list of species for the state, and compile the available information on their geographic distribution. We surveyed mammals at four sites during different periods (between 2010 and 2018), using camera traps and opportunistic observations. In spite of the differences in the sampling effort among the sites, we recorded 42 mammal species belonging to eight orders and 20 families. Our list includes rare and threatened species, such as the jaguar (Panthera onca), the giant anteater (Myrmecophaga tridactyla), and the lowland tapir (Tapirus terrestris). One species (Galictis cuja) was recorded in the state for the first time and the known range distribution of two others (Speothos venaticus and Alouatta caraya) was updated.

The state of Paraiba is one of those with the most degraded Caatinga that presents the large gap of knowledge concerning the mammal fauna. Mammals are among the taxa most affected by this. In this sense, we evaluated non-volant mammals’ richness and composition between March 2013 and February 2020 in a Caatinga fragment (121 ha). We used active search (336 hours) and camera traps (1,200 night traps). We recorded 20 species, including four threatened ones. Carnivora was the most representative order (7 species), followed by Rodentia (4 species). The richness of non-volant mammals found represents 35.6 % of the total number of such species in the Caatinga. This species richness is greater than that found in other studies in the state. The presence of these mammal species was mainly due to the recovering vegetation that resulted from the great planting effort and also due to cessation of hunt, cattle and sheep breeding that had existed on the farm for over thirty years. Our findings highlight the importance of this particular reserve due to the large number of species registered.

The southern cone of Mato Grosso do Sul state is poorly known in terms of mammal community composition. This information is very important to propose an environmental management plan. The present study provides information on the composition of medium and large size mammals in the municipality of Batayporã, in the Ivinhema river basin, southwestern Brazil. The mammal community was sampled during 19 field sampling occasions by the identification of vestiges, such as burrows, feces, vocalization and tracks, as well as through direct observations. I recorded 24 mammal species distributed in eight taxonomic orders. Thirteen species were frequently recorded, six species were rarely recorded, and six species are considered threatened in Brazil or in global level. The area presents almost half of the medium and large-sized mammal fauna from Mato Grosso do Sul state, but fragmentation and sugarcane plantations may represent a threat to the local biodiversity conservation.

AbstractThe Guiana Center of Endemism (GCE) extends across Guyana, Suriname, French Guiana, north of the Amazon River and east of the Negro River in Brazil, and Venezuela to the south of the Orinoco River. Regarding diversity of nonvolant mammals, the Brazilian part of this center is less studied, especially the area corresponding to the north of the State of Pará. Seven field trips lasting 12–15 days each were conducted in five conservation units in northern Pará, in order to assess the nonvolant mammalian fauna. Small mammals were captured using conventional and pitfall traps. Medium-sized and large mammals were recorded through direct observations on diurnal transect censuses, collections, camera traps, indirect evidence, and in some cases, interviews. We recorded 60 species distributed in nine orders. Among other contributions, a recently described species of

RESUMENEl estado de Aguascalientes es uno de los más pequeños de la república, y ocupa el lugar 29 por su extensión territorial. Dada su superficie territorial, su diversidad de mamíferos es una de las menores entre los estados del país. Aguascalientes no cuenta con una lista actualizada. Aquí reportamos 86 especies de mamíferos. El orden con mayor número de especies es Rodentia, seguido por el Chiroptera; ambos incluyen el 71% de la mastofauna del estado. No hay especies endémicas al estado, pero dos especies de murciélagos, seis de roedores y un carnívoro son endémicas de México. Según la norma oficial mexicana (NOM-059-SEMARNAT-2010) de especies en riesgo de extinción, la musaraña (Notiosorex crawfordi), el tejon (Taxidea taxus) y tres murciélagos (Choeronycteris mexicana, Leptonycteris nivalis y L. yerbabuenae) se encuentran en la categoría de Amenazada (A) y Leopardus pardalis (ocelote) está en Peligro de extinción (P). Palabras clave: Mamíferos, Aguascalientes, Estado de conservación.ABSTRACTThe state of Aguascalientes is very small in size and has a relatively small mammalian fauna diversity. There is not an updated checklist of the mammal fauna of the state, so here we reported 86 species; the orders Rodentia and Chiroptera are the most diverse and together comprised 71% of the mammal species. There are no endemic species in Aguascalientes, but two bat species and six rodents are endemic to Mexico. According to the Mexican endangered species act (NOM-059-SEMARNAT-2010), the dessert shrew (Notiosorex crawfordi), the American badger (Taxidea taxus), and three species (Choeronycteris mexicana, Leptonycteris nivalis and L. yerbabuenae, are listed as threatened species, and the ocelot (Leopardus pardalis) as endangered.

Favorable Conditions

Introduction. Airport territories are large, containing a high variety of biotopes, mostly open type, and are relatively protected against intense human activity, thus creating favorable conditions for many mammal species that serve as trophic source for many bird species. Material and methods. The studies were performed during 2012-2014 on the territory of Chisinau airport and within the adjacent ecosystems. The mammals were recorded by direct observations, based on traces and trophic activity on routes ranging from 1 to 3 km. The small mammals were assessed with traps. The bat species were identified according to their flight pattern and using the ultrasound detector. Results. In the airport, 31 species of mammals were registered: 5 insectivore species, 7 bat species, 14 rodent species, 1 hare species and 4 carnivorous species. The most widespread, common and abundant were the rodents and the fox. Among small rodent species, the most abundant was Apodemus sylvaticus with 51.6%, followed by the Microtus arvalis (38.9%), while on the airport grassland, the field vole dominated with more than 60%. The diet of Athene noctua included predominantly Mus musculus with over 51%, followed by M. arvalis with 23.7%. 7 species are rare and 5 protected – bicolor shrew and 4 bat species. Conclusions. The airport territory and adjacent ecosystems provide favorable conditions for many mammal species. The presence of rodents favors the occurrence of rather high number of prey birds, which represent a threat for the safety of aircraft flights. The fox can pose direct threat to flight safety.

Insight Into

Wilhelm Blandowski was the first zoologist employed by the Victorian Government, being appointed Officer of the Museum of Natural History by Governor La Trobe on 1 April 1854. Although he remained in this position for less than four years he left an important legacy by beginning the documentation of Victoria’s mammalian fauna before the full impact of European pastoralism and feral animals had become apparent. In particular, the 1856-57 zoological survey expedition to the lower Murray-Darling region provided a unique insight into the mammalian community that existed there before European occupation triggered a sudden decline in mammal species diversity, as happened progressively across the southern two thirds of Australia over the subsequent 90 years. Of the 34 mammal taxa recorded by the Blandowski Expedition, ten are extinct, nine no longer occur in the region, four are still present but with greatly reduced and fragmented distributions, seven have broad distributions in the region little changed since Blandowski’s time, although severely fragmented, and the remaining four have probably expanded their distributions. The contributions of Blandowski and his assistant Gerard Krefft to our understanding of the nature and causes of these mammal declines are examined and discussed. Unfortunately, the surviving contemporary documentation of the Expedition and the associated specimens is inadequate to shed much light on the factors that triggered the initial mammal declines, but the results do not support recent suggestions that predation by the introduced house cat Felis catus was pivotal.

ABSTRACT Variation in body size, behavior, feeding habits and habitat use patterns in medium- and large-sized mammals influence the adequacy of sampling methods to register presence and abundance. Moreover, even if methods are similarly adequate, different methodologies result in distinct cost-efficiency relationships (i.e. some may have reduced costs, be less time-consuming and/or require less-skilled technicians). Focusing on three different sampling methods commonly used to monitor medium and large mammals in seasonal tropical forests, we compared the species richness detected by each method and quantified their cost-efficiencies: (1) camera traps; (2) line transects for direct observations of animals; and (3) line transects seeking tracks/footprints. We simultaneously monitored medium and large mammals along five trails between July and August 2009 and January and February 2010, in the Serra do Japi Biological Reserve, São Paulo, Brazil. Data from two distinct seasons demonstrated that significantly higher species richness was achieved by using signs of presence and direct observations detected in transects. Camera traps recorded the fewest species, but represented the lowest cost per species. Direct observations and searches for tracks/footprints required a greater number of field technicians (with more skill and experience) to record the focal species and therefore have a higher cost, but allowed twice as many species to be recorded compared to camera traps. The choice of sampling methodology depends on the study objective, mammal species targeted and/or amount of resources available. We advocate use of camera traps for long-term studies and in conjunction with the other two methods to improve identification accuracy, allow individual identification and permit more accurate abundance estimates.

We present a species list of the mammals of the Estação Ecológica do Panga, a 404 ha Cerrado reserve in Minas Gerais state, Brazil. Using methods ranging from camera traps to direct observations, we documented 46 species in the reserve. Among medium and large-sized mammals, the order Carnivora was the most commonly observed (N=12 species). The highest relative frequencies of observation were of Mazama guazoubira and Cerdocyon thous. Pecari tajacu was the most frequent species in camera traps. Over the course of 7320 trap nights there were 105 captures of small mammals from seven species, with an overall capture rate of 1.6 %. The highest capture rates were for the marsupial Gracilinanus agilis, with Calomys tener the most commonly caught rodent. Our survey suggests that many of the Cerrado’s mammal species can persist in landscapes that are a mosaic of natural areas and some types of agriculture.
