Summary: This study examines the impact of restoration efforts on vocalizing fauna and social outcomes in a Central Indian tropical dry forest. The findings suggest that restoration does not significantly affect nocturnal vocalizing or stridulating species, but leads to lower acoustic space occupancy during daytime. In addition, participants value the cash payment they receive for participating in restoration and perceive lower crop raiding in restored sites. Recommendations include consulting local people about forest degradation and restoration, providing cash income for participation, and anticipating short-term changes in the faunal species community during invasive species removal.

Summary: Sound pressure levels are commonly used to describe the urban acoustic environment, but further concepts are needed to analyze its effects on human health. The soundscape ecology approach has gained traction, but high-quality sound recordings are essential for applying it to cities. The SALVE project aims to establish a high-resolution dataset of the urban AE and connect it to human health and the built environment.

Summary: Noise pollution poses a significant threat to ecosystems, and this study focuses on the impact of snowmobile noise on avian vocalizations. The research findings reveal that snowmobile noise leads to a decrease in bird vocalizations, but also highlight the resilience of avian communities. The study emphasizes the need to consider noise impacts in the non-breeding season and provides valuable insights for protecting critical avian habitats.

Summary: The study evaluated the performance of two models of GoPro underwater action cameras as PAM recorders, finding that they can reliably capture underwater acoustic recordings. Although not directly comparable with hydrophone-derived values, metrics derived from GoPros can be valuably compared between recordings taken using the same model.

Summary: The research found that bats in logged rainforests consumed a lower richness of prey, leading to less nested interaction networks with reduced network redundancy, making them more vulnerable to perturbations. Therefore, ecological interactions between old-growth and logged forests have changed significantly, potentially negatively impacting ecosystem function and network stability.

Summary: Recently developed non-invasive environmental DNA-based (eDNA) techniques have revolutionized modern conservation biology, making monitoring and managing natural populations more effective and efficient compared to traditional methods. However, the rapid expansion of eDNA technology may lead to confusion in terminology and collection/analytical processes, potentially hindering research progress, standardization, and practitioner adoption.

Summary: Humpback whale songs are structured with combinations, repeats, and sequences without clear silent intervals, resembling a continuous series of system states. Recurrence plots are used to describe animal behavior, visualizing and identifying traditional structures in humpback whale recordings, minimizing human bias and errors from transcriptions. The analytical tool efficiently identifies themes and songs from continuous recordings, providing a level of description independent of initial analysis.

Summary: Animal conservation translocation is an important tool for conservation biologists to address issues with isolated or endangered populations. Soft-release protocols are generally more successful than hard-release protocols, especially for reptiles. The success of the programmes is not influenced by the origin of the released animals, and the decision of which protocol to use should take into consideration financial costs.

Summary: The acoustic adaptation hypothesis posits that the acoustic signal of a species propagates better in its native habitat. A study on the advertisement calls of Pithecopus nordestinus examined the efficiency of signal transmission in two habitats and found that certain acoustic parameters, such as pulse interval and dominant frequency, influenced transmission. However, not all differences in acoustic parameters between environments could be attributed to the acoustic adaptation hypothesis.

Summary: This article reports on the sighting of an adult male sub-Antarctic fur seal in the Saint Peter and Saint Paul archipelago in Brazil, which is the first record of this species in the area. The researchers speculate that the seal may have originated from the nearby Gough or Tristan da Cunha islands and used ocean currents and/or shallower mid-ocean ridges for dispersal.

Summary: A study on the vocal interactions of maned wolves in captive and wild environments found that they engage in more vocal exchanges during mating and parental care periods. The duration of vocalizations differed between males and females, with males producing longer roar-barks. By analyzing the duration of vocal interactions, it was possible to infer the mating status of maned wolves. These findings highlight the importance of acoustic-based inferences in studying and conserving elusive species.

Summary: Acoustic communication plays a crucial role in information exchange among animals. However, anthropogenic noise can cause signal masking and affect effective communication. In this study, a meta-analysis was conducted to investigate the changes in acoustic parameters of insects, anurans, and birds when exposed to anthropogenic noise. The results showed that insects did not change their acoustic parameters, while anurans increased call amplitude and birds changed multiple acoustic parameters.

Summary: This study investigated the impact of mining noise on the vocalizations of black-tufted marmosets and how they adapt to noisy environments. The study found that areas near the mine have higher background noise levels and more frequent marmoset calls compared to distant areas. The spectral parameters of the calls in the near area also differed from those in the far area. These results suggest that mining noise can affect the acoustic communication of black-tufted marmosets and highlight the need for protective measures.

Summary: Habitat complexity is crucial for the welfare of captive animals, particularly in zoos. Greater enclosure complexity leads to a wider range of behaviors and improved physiological wellbeing. However, the benefits of habitat complexity should be specific to each species, as not all species would benefit. Therefore, it is important to provide and regularly evaluate habitat complexity for zoo animals. Complexity can change over time and space. This paper discusses how habitat complexity positively affects animal welfare and offers ideas on introducing habitat complexity and functional structures for captive animals.

Summary: This study investigated the effects of noise on the behavior of a male-female pair of sloths in a zoo in the UK. It was found that higher levels of noise were associated with decreased activity in the male and increased time spent inside a box for the female. After 24 hours, the female showed no behavioral changes while the male reduced foraging behavior. This indicates the importance of acoustic management in walk-through zoo enclosures where sloths are housed.
