“…(Hasenack and Cordeiro, 2006). Despite this wide array of threats, mammal surveys in the Brazilian Pampas are limited (Kasper et al, 2012a, b;Pinto and Duarte, 2013;Espinosa et al, 2016), especially regarding mammalian ecology and activity patterns.…”

Activity pattern of medium and large sized mammals and density estimates of Cuniculus paca (Rodentia: Cuniculidae) in the Brazilian Pampa

Between July 2014 and April 2015, we conducted weekly inventories of the circadian activity patterns of mammals in Passo Novo locality, municipality of Alegrete, southern Brazil. The vegetation is comprised by a grassy-woody steppe (grassland). We used two camera traps alternately located on one of four 1 km transects, each separated by 1 km. We classified the activity pattern of species by the percentage of photographic records taken in each daily period. We identify Cuniculus paca individuals by differences in the patterns of flank spots. We then estimate the density 1) considering the area of riparian forest present in the sampling area, and 2) through capture/recapture analysis. Cuniculus paca, Conepatus chinga and Hydrochoerus hydrochaeris were nocturnal, Cerdocyon thous had a crepuscular/nocturnal pattern, while Mazama gouazoubira was cathemeral. The patterns of circadian activity observed for medium and large mammals in this Pampa region (southern grasslands) may reflect not only evolutionary, biological and ecological affects, but also human impacts not assessed in this study. We identified ten individuals of C. paca through skin spot patterns during the study period, which were recorded in different transects and months. The minimum population density of C. paca was 3.5 individuals per km2 (resident animals only) and the total density estimates varied from 7.1 to 11.8 individuals per km2, when considering all individuals recorded or the result of the capture/recapture analysis, respectively.

“…The jaguar Panthera onca (Linnaeus, 1758) is restricted to one protected area, while the maned wolf Chrysocyon brachyurus (Illigier, 1815) was only recently rediscovered (Pinto and Duarte 2013) and is probably very close to extinction. The giant river otter Pteuronura brasiliensis (Gmelin, 1788) disappeared from this region in the 1950s, as has the bush dog Speothos venaticus (Lund, 1842), which probably occurred in southern Brazil and northeastern Argentina in the past (Fontana et al 2003).…”

Trophic relationships of sympatric small carnivores in fragmented landscapes of southern Brazil: niche overlap and potential for competition

et al. 2016

Between 2000 and 2010, digestive tracts collected from carnivore carcasses found in southern Brazil were analyzed to determine the frequency and proportion of items constituting the diets of each species. Material was collected and analyzed from 194 animals of 10 species: Cerdocyon thous, Lycalopex gymnocercus (Canidae), Procyon cancrivorus (Procyonidae), Galictis cuja (Mustelidae), Conepatus chinga (Mephitidae), Leopardus colocolo, Leopardus geoffroyi, Leopardus guttulus, Leopardus wiedii, and Puma yagouaroundi (Felidae). Most of these species are sympatric, which makes them potential competitors when sharing, to a greater or lesser degree, the same resources. The food niche breadth was relatively narrow, demonstrating that even generalist species, such as the crab-eating raccoon, used food resources rather unequally. An extensive overlap ( > 90%) in food niches was found among the cat species, the grison, and the Pampas fox, which had diets based on rodents. Crab-eating raccoons occupied a different food niche, based on aquatic or semiaquatic prey and fruits. Conepatus chinga was unique in exploiting arthropods and insect larvae as basic dietary items.

“…The silvicultural plantations that have a mosaic of associated areas of preserved native habitats or in recovering process, either as permanent preservation areas (Área de Preservação Permanente -APP) or legal reserves (Reserva Legal -RL) (Brasil, 2012), may play a positive role in the conservation of local biodiversity (Mazzolli, 2010;Bonilla-Sánchez et al, 2012;Pinto and Duarte, 2013;Campos et al, 2018). According to Lindenmayer et al (2009), patches of native forest fragments and riparian forests suffer a lower impact on their biologic diversity when the adjacent area is forest plantations.…”

“…The record of maned wolf (Chrysocyon brachyurus) and several felines (Leopardus geoffroyi, Leopardus wiedii, Leopardus colocolo, Leopardus yagouaroundi), among other mammals in areas of forestry consorted with cattle ranching in the Pampa biome (Pinto and Duarte, 2013) indicates that studies on species diversity should also consider the edge and interior species of gallery forests, generally very threatened in areas with other agricultural activities, due to the destructuring of these forests (Costella et al, 2013;Kliger and Ginzburg, 2022).…”

Over the last decades, agribusiness has shown a great expansion in the Pampa Biome. Forestry, mainly with eucalyptus, has expanded its planting in the Rio Grande do Sul state, southern Brazil. The objective of this study was to contribute to the understanding of the impact of planted forests on Brazilian Pampa biodiversity, through the comparison of the relative abundance of Nothura maculosa in areas of native field and areas with young (aged 6–12 months) eucalyptus. Pointing dogs were used to define the relative abundance (individuals per hour) of N. maculosa on 16 farms and ten eucalyptus plantations. A total of 307 individuals of N. maculosa were recorded on the 26 sampled properties, of which 188 were found in grasslands (average of 12.6 ind.h-1) and 119 in eucalyptus plantings (average of 13.5 ind.h-1). No statistically significant differences were found between the sampled areas (p = 0.18; α = 0.05). The main conclusion of this study is that when the landscape spatial-temporal mosaic is considered, the term “green desert” become quite limited.
