The rapid increase of urbanization across the tropics has transformed natural landscapes into intensely modified environments, challenging native species to thrive in human-dominated spaces. Frugivorous bats perform vital ecological roles in urban landscapes, preventing the further decline of seed dispersal dynamics. The “cumbaru” tree Dipteryx alata – a large native species widely distributed throughout Cerrado savannahs of South America – serves as an important food resource for wildlife. In this study, we documented and quantified the cumbaru potential dispersal performed by Artibeus sp. in an urban area located in the limits between Cerrado and Pantanal (Cáceres municipality, Mato Grosso, Brazil). Our results revealed that, during 21 nights of observation, individuals of Artibeus sp. transported 27 fruits at a distance of approximately 35 m. Our observations on the dynamics of seed dispersal by bats in an urban context provide preliminary, but important, insights for management actions to ensure the maintaining of species interactions and biodiversity conservation across human-dominated landscapes.

Genetic techniques have allowed to identify a number of cryptic species of bats and to better define their distribution ranges and conservation status. Long-eared bats Plecotus spp. occur throughout Eurasia and Africa, with a high number of morphologically similar species, often occurring in sympatry. Therefore, disentangling the distribution of one species from another may be challenging. Italy represents a diversity hotspot for long-eared bats in Europe, hosting six species belonging to the genus Plecotus. In this study we report on both published and unpublished investigations on the Alpine long-eared bat Plecotus macrobullaris by integrating field and molecular methods, as well as opportunistic verified records from citizen scientists (i.e., individuals showing the diagnostic triangular chin pad in photos), to redefine the distribution of this species in Italy. We retrieved a total of 149 published records and 16 new confirmed records, namely 7 from iNaturalist, 6 from Facebook and 3 from molecular analyses. In Italy, the species occurs throughout the Alpine and Pre-Alpine chain, as well as in close proximity to the sea, and in Northeastern plains. Based on new records, we proved that it occurs also in other areas, including the Northern Apennine ridge. Our findings call for the application of an integrated approach in investigating cryptic species, that provides valuable data to support conservation assessments and the establishment of proper protection measures for poorly known species.

No single studies on the Burmese Red Serows, a little known bovid to date yet considered as nationally endangered species, have been conducted in Bangladesh. As part of a systematic wildlife inventory and monitoring project, this study utilized 48 camera traps to elucidate their occurrence, activity pattern and possible sympatric association with other artiodactyls species inhabiting Baraiyadhala National Park. The study found 25 independent serow events with relative abundance index (RAI) of 0.89. The number of individuals seems low, but this is by far the country’s stronghold population. The Red Serows are mostly nocturnal and showed moderate temporal activity with barking dear (∆1 = 0.59) and wild boar (∆1 = 0.62) in this area. Anthropogenic pressures due to tourists (RAI = 4.8) and poachers (RAI = 1.7) were highly evident and must have negative impact on overall wildlife of the national park. The study suggests similar studies in adjacent protected area (Hazarikhil Wildlife Sanctuary), habitat protection and restoration program, and awareness raising program targeting forest dependent communities for long term conservation of this species.

The determination of suitable habitats and roadkill hotspots allows for the prioritization of areas of conservation and the identification of road sections that require appropriate planning and development. Understanding the factors that influence the species’ presence and those contributing to its road-related fatalities is crucial. This study demonstrates the use of MaxEnt modeling to map the potential distribution of the striped hyaena (Hyaena hyaena) in Batna province (East Algeria) using occurrence records and a set of environmental variables. The results indicated that the two primary environmental variables that influence the distribution of the species are the shrubland, and the slope with a contribution of 37.5 and 30.2 %, respectively, followed by built-up areas (12 %) and distance to roads (7.2 %). The species may occupy steep terrain with shrubland near anthropized areas. Road collisions represent a threat to the species, with 28 documented casualties from 2010 to 2020 in Batna. The kernel density estimation revealed an important roadkill hotspot along the national roads 3 and 28. This study represents a preliminary step for the use of wildlife ecological niche modeling and road management in Algeria.

We examined the feeding habits and seasonal changes in invasive masked palm civets (Paguma larvata) in northern Japan, to understand their feeding strategies. Between 2020 and 2022, we collected 98 fecal samples from masked palm civets and analyzed their content. The civets fed mainly on fruits (78 % in terms of the point-frame method) and arthropods (15 %); fruits were consumed throughout the year, but increased in winter when arthropods were not available. The feeding plasticity of masked palm civets, in addition to their physical and behavioral adaptations, enables them to expand their distribution in introduced habitats in temperate regions.

Amazonian tropical forests host the highest bat diversity in South America. The central area Brazilian Amazon encompasses one of the largest pristine areas within this biome, where Amanã and Mamirauá Sustainable Development Reserves (SDRs) are located. These two reserves hold the status of Priority Areas for Biodiversity Conservation due to their high biological relevance. The aim of this study was to identify the bat species richness within these SDRs to minimize the Wallacean shortfall of the chiropterofauna in the Amazon. A total of 274 specimens, collected 20 years ago and housed in the mammal collection at the Museu Paraense Emílio Goeldi, were sorted and identified. They are distributed across four families, 18 genera, and 26 species: Artibeus planirostris and Carollia perspicillata were the most abundant vouchers. We identified a range extension for Carollia benkeithi and a possible new taxon for the genus Micronycteris.

The Giant Anteater (Myrmecophaga tridactyla), facing threats from habitat degradation and hunting, remains a species of enigmatic behavior. This study analyzed camera trap data collected over 7700 camera trap nights in 49 stations near marked trees in Southern Guyana. A total of 883 Giant Anteater sightings were recorded, categorized into solitary adults (797), females with offspring (70), solitary juveniles (8), and paired adults (6). Meticulous observations documented various behaviors, distinguishing chemical (sniffing) and visual (scratching, climbing, hugging, rubbing) tree-marking from non-tree-marking behaviors (foraging, self-scratching, rolling, urinating/defecating). For solitary individual, a PCA revealed an inverse correlation between ignoring and sniffing (explaining 33.64 % of PC1), suggesting individuals engage in one behavior per observation. We observed an inverse correlation between hug/scratch/rub and climb (20.75 % of PC2). A weighted PCA assessing correlations by social categories, distinguishing marking behaviors from ignoring the tree (explaining 95.6 % of PC1). Scratching trees without climbing or hugging occurred from 3 pm to 1 am, with climbing most frequent between 8 and 10 pm. These behaviors were common during peak anteater sightings, peaking in May, with fewer observations in September. Overall, Giant Anteaters exhibit tree-marking behaviors, including scratching, climbing, and hugging and that a primary purpose for this behavior is communication.

The bushy-tailed opossum Glironia venusta is a rare marsupial from Amazonia, with most of the known records obtained through scant visualization/photography events or by few captures/deposit of specimens in scientific collections. This study presents unusual records for the species: the first record of individuals dead due to vehicle collision, and a specimen opportunistically trapped into a mistnet. The data presented herein provide additional morphometrical data and ecological insights about G. venusta. Although this species is considered essentially arboreal, our records indicate that movements on ground are part of its habits.

The marsh rat (Holochilus chacarius) is considered a specialist herbivorous rodent. In this study, we report the first predation event of an anuran (Pseudis platensis) by a marsh rat in the Pantanal wetlands, South America. This unprecedent event in a flooded wetland in the municipality of Corumbá, Mato Grosso do Sul state, southwestern Brazil. Due to the flashlight, the rodent ceased its predatory activity and left, carrying the anuran in its mouth. Our findings contribute to the natural history of the marsh rat, highlighting that this herbivorous rodent can incorporate fresh animal matter into its diet.
