Because this subspecies prefers coastal environments, it constantly experiences the impacts caused by human activities, some examples being: incidental catches in fishing nets, environmental degradation (chemical, residual and noise pollution), depletion of its prey, intru-sions and human disturbances caused by activities such as uncontrolled urban growth and acci-dental collisions with vessels, leading these animals to exhibit stress. Given the importance of acoustic communication for the ecology and survival of these animals, this study aimed to eval-uate, classify, and describe the vocalizations of the species, as well as identify underwater noises in the Barra da Laguna de Tramandaí (RS). Acoustic monitoring took place over three days in January 2023, using a C57 hydrophone and a Tascam DR-100 MKIII recorder. The recordings were analyzed using Raven Pro software version 1.6.5 (Cornell Lab of Ornithology, 2019). The results obtained were from 191 whistles, which were analyzed, obtaining an average duration of 0.30 ± 0.13 s, with whistle frequencies ranging between 2.7 kHz and 21.4 kHz; these values are compatible with records of Tursiops spp. The qualitative analysis identified six modulation patterns, the most frequent being: ascending (A): 44.5%, parabola (C): 20.9%, de-scending (B): 15.2%. The ecological importance of the research is reinforced by the identifica-tion of "anthropophony," which consists of noise of human origin, evidenced in the soundscape at the study site. The noise caused by boat engines, for example, occurs in frequency ranges below and beyond the frequency range of the acoustic repertoire of the species in question, which ultimately reduces the communication, navigation, and foraging capabilities of dolphins, representing a critical risk for a population that is already endangered, indicating a high risk of extinction in the wild. This work demonstrates that acoustic monitoring is an essential tool, mainly because it is non-invasive, serving to evaluate, classify, and describe vocalizations in the underwater environment. Acoustic monitoring allows us to observe whether the species may exhibit behaviors such as increasing the maximum frequency of its whistles to compensate for excessive noise, which can be an indicator of ecological stress.

Considering the importance of understanding these interactions, this study aimed to survey zoonotic diseases affecting wild animals in Brazil and discuss their impacts on species conservation. The research was conducted through a bibliographic review of studies published between 2014 and 2025, including books, book chapters, scientific articles, theses, dissertations and technical reports. A total of 193 wild species affected by 49 zoonoses were recorded, with mammals being the most impacted group, particularly by diseases such as Chagas disease, leptospirosis, rabies, toxoplasmosis, and leishmaniasis. The results demonstrate that these diseases have the potential to cause harm to wild populations and highlight the importance of further studies to clarify remaining knowledge gaps. The constant monitoring of zoonoses in wildlife is essential for the preservation of fauna and for preventing ecological impacts and reemerging diseases.

In this context, the present study aimed to survey medium- and large-sized mammals at the Erechim Campus of the Federal University of Fronteira Sul, in order to estimate species richness, composition, and spatial distribution. Sampling was conducted over six months, from October 2024 to March 2025, using Bushnell HD camera traps for mammal detection. A total of 11 species were recorded, belonging to six orders and nine families, including three classified under some level of threat of extinction (national or state level). The presence of threatened species highlights the ecological importance of the Erechim Campus of the Federal University of Fronteira Sul, indicating that the site serves as an important refuge for these species. Therefore, the preservation and proper management of forest fragments are essential for the local conservation of mammalian fauna, contributing to the survival of threatened species and the maintenance of mammal populations.

In this context, arbuscular mycorrhizal fungi (AMF) have been studied as an ecological alternative to mitigate the toxic effects of Cd in plants. The objective of the present study was to systematically review the scientific literature of the past five years in order to assess the reported effects of AMF inoculation on plant tolerance to Cd. Searches were conducted in the Web of Science and Scopus databases, followed by bibliometric analysis using R software and the RStudio interface, as well as screening of eligible studies. In the end, of the 51 articles processed by the program, 16 met the inclusion criteria. The results indicated that AMF inoculation promotes physiological and morphological benefits to plants, such as increased biomass, photosynthetic efficiency, antioxidant activity, and reduced Cd translocation. Furthermore, the combination with biochar, humus, and fertilizers enhances these beneficial effects. However, the predominance of studies under controlled conditions limits the extrapolation of the results to real environments, highlighting the need for more field research. This systematic review contributes to consolidating current knowledge on the subject and provides insights for future investigations in the context of regenerative agriculture, considering the role of AMF in soil quality restoration, reduction of Cd toxicity, and the promotion of more resilient agricultural systems.
