While the occurrence and function of vocalisation by pikas has been studied (genus Ochotona), little is known about vocalisation by hares (genus Lepus). In this study, we investigate the vocalisation activity of mountain hare (Lepus timidus) over the course of a year to better understand its occurrence and function. We found that mountain hares have a low vocalisation rate of one vocalisation every 33 night hours. We hypothesise that this low rate is the result of a strategy to minimise detection by predators. However, the 20 recorded vocal events correspond with intraspecific communication events such as warning others about danger and defending resources. This case study identifies further research directions to help strengthen our understanding of communication between solitary hares.

Rodent pups emit ultrasonic vocalizations (USVs) to solicit maternal behavior, promoting their survival. Conversely, maternal behaviors affect the expression of pup USVs. We previously demonstrated that a maternal diet high in saturated fat (HFD) alters maternal behavior and is associated with early maturation of pups and their stress physiology. Here, we assessed the developmental profiles of pup USVs using quantitative and qualitative measures on postnatal days (PND)7 and 13. Quantitative measures included call counts, duration, and frequency, while qualitative measures examined calls' sonographic structures. HFD offspring lacked the typical decrease in USV numbers with age observed among control offspring. They also had shorter calls at PND7 compared to control and HFD offspring at PND13. HFD female offspring showed a greater number of one‐frequency‐sweep calls, while male pups showed a greater number of two‐frequency‐sweep calls compared to control offspring. Concomitantly, HFD dams showed impaired pup retrieval on PND7. The data suggest that fewer USVs of shorter duration in HFD offspring may alter dam solicitation and thus impair maternal pup retrieval. This study highlights the impacts of perinatal HFD exposure on the dyadic reciprocal interaction between dam and pups, which may set the stage for long‐lasting effects on offspring physiology and behavior.

We obtained the first records of Sciobia (Thilptoblemus) natalia in Europe after a single record from Algeciras (Spain), about one century ago. We found the species in Tarifa, Benelup-Casas Viejas and Alcalá de los Gazules (Cádiz province) in plots with open land and herbaceous vegetation of wasteland, cattle states, edges of agricultural land, and hedgerows of pathways and local roads. The species may be common locally, in late spring. It may coexist with Sciobia (Thliptoblemus) caliendrum although the later presents a wider ecological spectrum whereas S. (T.) natalia prefers dense vegetation in more humid soils. Acoustic analyses indicate that the song of both species are very different, making field identification feasible. S. (T.) natalia may however easily go unnoticed among populations of the more conspicuous S. (T.) caliendrum. We discuss possible reasons why this species has gone unnoticed so far and factors that may pose at risk the maintenance of its populations.

This study characterizes the calling song and ultramorphology of the stridulatory file of two geographically isolated populations of the tropical bush cricket Eneoptera surinamensis (De Geer, 1773) from city of Foz do Iguaçu, state of Paraná, and town of Rio Claro, state of São Paulo, Brazil, distant 1,000 Km from each other. The teeth are shell-shaped, the larger ones are dis tributed in the medium region of the file, decreasing gradually in size towards the edges. Specimens from Foz do Iguaçu have a file with 82 ± 9.8 teeth, length=1.89 mm ± 0.15 with 43.76 ± 5.94 teeth per mm (n=15). Specimens from Rio Claro present a file with 87 ± 9.81, length=1.9 6 ± 0.19 mm with 44.52 ± 4.61 teeth per mm (n=15). Statistical differences found between the two populations are not significant. The calling song is an uninterrupted trill that alternates two sets of notes distinct for its temporal features.
