Monitoring Programs

The aim of this study was to survey the species of large and medium-sized terrestrial mammals occurring at Serra do Brigadeiro State Park (SBSP). Data was compiled from two studies carried out in 2008. Data was collected through sand plots and camera traps. Thirteen species were recorded, one that had not been registered before (Leopardus wiedii) and one exotic (Canis lupus familiaris). Species richness estimate for camera trapping was 13.53±1.75. For the sand plots, estimate was lower (9±1.73 species). The low number of inventories focusing on large and medium-sized terrestrial mammals in the Mantiqueira region of the Atlantic forest and the presence of the domestic dogs within the Park limits emphasizes the need for monitoring programs to identify the major threats to preserved areas in the region.

Potential Impact

Presence of exotic species in forest remnants is a major concern for the conservation of wild species, not only on islands, where potential impact is higher. Although the problem is widespread and increasing, there are few studies on Neotropical forests. Here we quantify the occurrence of domestic dogs (Canis lupus familiaris) in an Atlantic forest reserve in south-eastern Brazil (Santa Lúcia Biological Station - SLBS). Throughout two years of monitoring with camera traps (2,142 camera-days), 25 records of 16 individual dogs were obtained in the interior of SLBS, making dogs the fourth most frequently recorded species of mammals in general and the first-ranking among Carnivora, ahead of the ocelot and puma, the top two terrestrial predators present in SLBS. Dogs entered the forest year round, in almost half of the sampled months (48%), and predominantly during daytime (89%). They were detected in various trails inside the reserve, but mostly in areas nearest to the reserve's border (<200 m from the edge). Record rates of domestic dogs did not correlate significantly with climate variables, with frequency of mammal records and richness in general, or with any particular mammal species (Spearman rank correlation, p > 0.05 in all cases), suggesting an erratic, non-seasonal pattern of entrance in the reserve. Data indicate that domestic dogs can be abundant and frequent visitors to little disturbed Atlantic forest reserves even when these are located in regions of low density of human population. The potential impact to native fauna is discussed.

Assessing the species diversity in non-conservation areas is crucial to understanding for conservation interventions and management. We used camera trapping to investigate the species diversity in the Batang Angkola Landscape in North Sumatra. The study on species diversity in the area was conducted in 5 months from February to June 2020. The aim of this study is to assess the species diversity in Batang Angkola landscape as a reference for the improvement of the management and policy with a special interest in proving the existence of wildlife species in the landscape. We compiled a species diversity, richness and evenness investigated conducted a test to Shannon wiener analyses. Based on 1,283 photograph at 60 camera traps stations during 2,923 trap days, we identified 27 different species (24 species are terrestrial mammals, 2 species are birds, and 1 species is reptile), including five classified as threatened according to the IUCN. Based on the calculation of the Relative Abundance Indices for each species per 100 trap days, pig-tailed macaque  had the highest RAI (3.63 photograph /100 trap days), followed by wild boar and muntjac were (1.33 and 1.27 photographed/100 traps days respectively). Based on Shannon Weiner analysis shows the analysis of species diversity (H), which showed that in the northern and southern areas it was moderate (2.40 and 2.45 respectively). The level of evenness between north and south areas shows high evenness (0.77 and 0.79 respectively). The level of species richness between north and south shows moderate to high levels in the two areas (3.95 and 4.42 respectively). Our findings suggest that Batang Angkola Landscape supports a high species richness. Continued survey efforts need to be combined with detailed ecological data collection and effective management in the region.Menilai keanekaragaman spesies di kawasan non-konservasi sangat penting untuk memahami upaya pengelolaan dan intervensi konservasi. Kami menggunakan camera trap untuk menyelidiki keanekaragaman spesies di Bentang Alam Batang Angkola di Sumatera Utara. Kajian keanekaragaman jenis di kawasan ini dilakukan selama 5 bulan dari Februari hingga Juni 2020. Tujuan penelitian ini adalah untuk mengkaji keanekaragaman jenis di bentang alam Batang Angkola sebagai acuan perbaikan tata kelola dan kebijakan, spesifik pada membuktikan keberadaan spesies satwa liar. Data keanekaragaman spesies, kekayaan dan kemerataan yang kami kumpulkan, dianalisis dengan Shannon wiener. Berdasarkan 1.283 foto di 60 stasiun perangkap kamera selama 2.923 hari rekam, kami mengidentifikasi 27 spesies berbeda (24 spesies mamalia darat, 2 spesies burung, dan 1 spesies reptil), termasuk lima jenis yang diklasifikasikan sebagai satwa terancam menurut IUCN. Berdasarkan perhitungan Indeks Kelimpahan Relatif untuk setiap spesies per 100 hari rekam, beruk memiliki RAI tertinggi (3,63 foto / 100 hari rekam), disusul babi hutan dan kijang (masing-masing 1,33 dan 1,27 foto / 100 hari rekam). Berdasarkan analisis Shannon-Weiner untuk keanekaragaman jenis (H) menunjukkan bahwa di wilayah utara dan selatan dalam kategori sedang (masing-masing 2,40 dan 2,45). Tingkat kemerataan antara wilayah utara dan selatan menunjukkan tingkat kategori kemerataan yang tinggi (masing-masing 0,77 dan 0,79). Tingkat kekayaan spesies antara utara dan selatan menunjukkan kategori tingkat sedang hingga tinggi di kedua wilayah tersebut (masing-masing 3,95 dan 4,42). Temuan kami menunjukkan bahwa Bentang Alam Batang Angkola mendukung kekayaan spesies yang tinggi. Upaya survey lanjutan perlu digabungkan dengan pengumpulan data ekologi yang terperinci dan pengelolaan yang efektif di wilayah tersebut.

The City

We surveyed, with the aid of camera traps, medium-sized and large terrestrial mammals in 8 patches of semideciduous Atlantic Forest near the city of Alfenas, Minas Gerais, Brazil. We recorded species occurrence using 2 camera traps per fragment, which were simultaneously active for 2 months each. We recorded 16 species, plus a species of armadillo that we were unable to identify to genus. The rarefaction curve tended to stabilize, evidencing the efficacy of our methods. The species richness was similar or higher to other surveys carried out in remnants of seasonal semideciduous Atlantic Forest or transitional areas. However, such seemingly high richness in a severely degraded and fragmented region, including large carnivores and endangered species, hides a wide variation in richness among fragments. This calls for urgent actions to improve the landscape for these animals to ensure their survival in the long term, as some populations are probably not viable in the long run.

Donor Cells

Interspecies somatic cell nuclear transfer (iSCNT) is an emerging assisted reproductive technology (ART) for preserving Nature’s diversity. The scarcity of oocytes from some species makes utilisation of readily available oocytes inevitable. In the present study, we describe the successful cloning of coyotes (Canis latrans) through iSCNT using oocytes from domestic dogs (Canis lupus familiaris or dingo). Transfer of 320 interspecies-reconstructed embryos into 22 domestic dog recipients resulted in six pregnancies, from which eight viable offspring were delivered. Fusion rate and cloning efficiency during iSCNT cloning of coyotes were not significantly different from those observed during intraspecies cloning of domestic dogs. Using neonatal fibroblasts as donor cells significantly improved the cloning efficiency compared with cloning using adult fibroblast donor cells (P < 0.05). The use of domestic dog oocytes in the cloning of coyotes in the present study holds promise for cloning other endangered species in the Canidae family using similar techniques. However, there are still limitations of the iSCNT technology, as demonstrated by births of morphologically abnormal coyotes and the clones’ inheritance of maternal domestic dog mitochondrial DNA.

Medium and large-sized terrestrial mammals develop important functions in ecosystems maintenance. However, this group is the most vulnerable to local extinctions, through habitat loss or hunting. This study inventoried the community of medium and large mammals in the Reserva Ecológica de Guapiaçú (REGUA), Cachoeiras de Macacu, RJ, providing data on species composition, richness and abundance. Species were registered through the use of camera traps, sign survey and visual encounters on pre-existing trails and roads. The study was conducted from January to October 2012, with each month considered as a sample unit. An effort of 1568 cameras-day and 120 km traveled, resulted on 302 records of 22 species of medium and large-sized mammals, belonging to eight orders. This value corresponds to more than three-quarters of the richness described from this group in the Atlantic Forest of Rio de Janeiro state. Five species are under some level of regional, national or global threat. Three game species, Pecari tajacu, Cuniculus paca and Dasyprocta leporina were abundant in the area. The observed richness was comparable to that found in other studies conducted in rain forests. Thus, for its high number of species, including those under some degree of threat, we conclude that REGUA is an important area to mammal conservation, especially in the Atlantic Forest of Rio de Janeiro state.

Environmental Functions

The fragmentation process that has altered natural environments has been widely discussed, as it causes changes in communities and compromises different environmental functions. In this sense, this study was based on the evaluation of fragmentation on araneofauna of semideciduous seasonal forest fragments, phytophysiognomy belonging to the Atlantic Forest. The study was conducted in three fragments in the municipality of Inconfidentes, southern Minas Gerais, from April 2014 to March 2015. The results showed that there is a similarity in the composition of spider species among the sampled fragments and that the size of the fragment is positively correlated with species richness. Our data show that smaller fragments must be preserved and that agricultural areas maintain the integrity of adjacent forest areas to benefit from the predation dynamics that spiders exert on pests that affect plantations.

The objectives of this study were to identify anthophilous butterflies on psychophilous flowers of four Asteraceae species in an Atlantic Forest fragment in Viçosa, Minas Gerais State, Southeastern Brazil, and to determine whether there are species in common with other lepidopteran inventories of the Southeastern and Midwestern regions of Brazil. It is the first inventory of anthophilous butterflies of a semideciduous forest fragment in Zona da Mata, State of Minas Gerais. A total of 108 species were recorded, representing the fourth largest lepidopteran survey in this State. The results demonstrated that Asteraceae species may be important tools for monitoring anthophilous butterflies. The similarity with other inventories ranged from 1 to 92.55%. Fifteen species were reported for the first time in the State of Minas Gerais, and among them, Melanis alena and Thisbe irenea were observed in this study only.

Although highly diverse (Fonseca et al. 1996), the Atlantic forest mammal fauna is still poorly known, with very few sites exhaustively inventoried or subjected to long-term studies (Passamani et al. 2000). Although the first surveys using camera traps were carried out in the 1920s (e.g. Chapman 1927), most studies are rather recent (Karanth & Nichols 1998). This is not different in Brazil, where few studies have been published (Marques & Ramos 2001, Santos-Filho & Silva 2002, Silveira et al. 2003, Trolle 2003, Trolle & Kéry 2003). Given this, the objective of this paper is to assess the efficiency of camera trapping as an inventory technique for Neotropical forests in general and Atlantic forest in particular. The study was conducted at the Santa Lúcia Biological Station (SLBS), a biologically rich Atlantic Forest preserve located in south-eastern Brazil (Mendes & Padovan 2000) where mammals have been intensively live-trapped, observed from line-transects or had indirect evidence of their presence (faeces, footprints, scratches, etc.) recorded in earlier years (Passamani et al. 2000).
