In this study, we explored the vocal repertoire of <i>D. volitans</i> by analysing sounds opportunistically acquired by an action camera during a field survey in the south Adriatic Sea (Croatia). The acoustic repertoire was composed of two distinct sound types (Grunt A and Grunt B) produced in an alternating order. Grunt A was a harmonic sound composed of two to nine pulses that lasted around 30 ms. They were produced singly or in trains (bursts), and we could differentiate short- and long-intervals between the sounds within the bursts. Grunt A was harmonic and possessed up to six harmonics, with the peak frequency of around 225 Hz. Grunt B, composed of two to four pulses and lasting around 110 ms, had overlapping peak and fundamental frequencies (~170 Hz). In addition, we recorded several sounds of juvenile <i>D. volitans</i>. By examining the anatomy, we provide insights into the swim bladder mechanism and other anatomical features of the skull and vertebral column. The large swim bladder was separated along the midline into two rostrocaudal chambers, and the walls of each chamber were surrounded by highly vascularized intrinsic sonic muscles. The skull of <i>D. volitans</i> possessed two large openings situated posteriorly; the anterior extensions from the swim bladder fitted into these openings, hence shortening the distance between the bladder and inner ear. Our study establishes <i>D. volitans</i> as a sonic species, paving the way for future bioacoustic surveys to provide valuable insights into its status and distribution in the Adriatic Sea.</p>","PeriodicalId":17600,"journal":{"name":"Journal of Zoology","volume":"328 4","pages":"346-359"},"PeriodicalIF":1.6,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148045546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eastern hellbenders (<i>Crytobranchus alleganiensis alleganiensis</i>) have suffered range-wide declines, with elevated conductivity proposed as a major contributor, particularly for early life stages. However, the mechanisms through which conductivity affects hellbenders at these early life stages remain poorly understood. We experimentally assessed the effects of chronic exposure to elevated conductivity (1000 μS cm⁻¹) on wild eastern hellbender larvae over 91 days posthatching, as well as the effects of switching between low conductivity (100 μS cm⁻¹) and high conductivity after 30 days of exposure. Chronic high conductivity resulted in ~50% higher larval—but not egg—mortality compared to low controls. Larvae switched from low to high conductivity experienced a ~17% increase in mortality compared to their unswitched counterparts, whereas those switched from high to low conductivity exhibited a ~25% decrease in mortality compared to those that remained in high. Chronic exposure to elevated conductivity reduced body mass and altered morphology, with similar effects observed in animals switched from low to high conductivity. Conversely, switching animals from high to low conductivity only marginally improved growth and did not fully compensate for initial deficits. Despite altered size and morphology, locomotor performance was unaffected. Whole-body cortisol, a measure of stress, and lipid peroxidation, a marker of oxidative stress, did not differ across treatments. Collectively, these results indicate that elevated conductivity can contribute to hellbender population declines through both lethal and sublethal effects.

Red deer shows a particular preference for forest gaps, whereas the elevated browsing pressure can limit tree regeneration. Nevertheless, intra-forest meadows can attract red deer within forests by providing accessible grass, particularly as warmer winter temperatures, driven by climate change, result in earlier vegetation onset and lower snow cover. Using GPS monitoring of red deer in two populations from France and Belgium, we analysed how their selection of intra-forest meadows varies according to season, seasonal mean temperature and time of day (night-time and daytime). We show that red deer preferentially selects intra-forest meadows at night, irrespective of the season, although the strength of this selection is reduced in winter. However, the strength of night-time selection of meadows increases with winter mean temperature. We proposed that this pattern is explained by seasonal variations of vegetation availability (minimal in winter), which is positively linked to winter temperature. These results suggested that meadows act as critical foraging areas for red deer across all seasons in a climate change context with warmer winters. We also hypothesised that intra-forest meadows modify the spatial distribution of browsing pressure within neighbouring forest areas, a key issue for forest managers.</p>","PeriodicalId":17600,"journal":{"name":"Journal of Zoology","volume":"328 4","pages":"325-335"},"PeriodicalIF":1.6,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148045594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the factors that influence intraspecific dietary variation in mesocarnivores, which are major omnivorous mammals, remain poorly understood. This study aimed to reveal the relative effects of internal factors (sex and genetic relatedness) and external factors (season and environmental dissimilarity) on intraspecific dietary variation in raccoon dogs (<i>Nyctereutes procyonoides</i>). We collected fecal samples monthly from May to November 2022 on Okushiri Island, Hokkaido, Japan. Diet was assessed through fecal content analysis. Sex identification and estimation of genetic relatedness were conducted using fecal DNA analysis, and environmental dissimilarity at sampling sites was evaluated by GIS-based assessments. Dietary differences between seasons (summer: <i>n</i> = 137, autumn: <i>n</i> = 128) and sexes (male: <i>n</i> = 148, female: <i>n</i> = 117) were evaluated using PERMANOVA. To identify the factors shaping dietary variation, we used multiple regression on distance matrices with dietary composition as the response variable and environmental dissimilarity and genetic relatedness as explanatory variables. Our results showed that external factors (season and surrounding environment) had a significant effect on raccoon dog diets, whereas internal factors (sex and genetic relatedness) had no significant effect. These findings suggest that intraspecific dietary variation in raccoon dogs is primarily shaped by differences in local resource environments rather than by individual traits. This dietary flexibility may support their adaptability to diverse environments and enable them to flexibly form trophic interactions, potentially contributing to ecological stability.</p>","PeriodicalId":17600,"journal":{"name":"Journal of Zoology","volume":"328 4","pages":"336-345"},"PeriodicalIF":1.6,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148045569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On land, turtles are at risk of being overturned onto their carapace, which can lead to issues such as breathing difficulties, overheating, dehydration, starvation or predation. Thus, the ability to return to an upright position is essential for their survival. So far, the relationship between antipredator behaviour and self-righting has received limited investigation, and the potential effects of body condition and muscular strength have not yet been assessed in natural populations of turtles. In this study, we investigated the factors influencing locomotor performance and antipredator behaviour in the European pond turtle (<i>Emys orbicularis</i>) by testing 436 adult individuals in five remote populations using a self-righting test after a simulated predator attack. Smaller adults were more successful at self-righting than larger ones, and individuals with relatively greater muscle strength and better body condition self-righted more quickly. Our results reveal local adaptation in locomotor performance and antipredator behaviour. For example, turtles from heavily fished areas reacted significantly faster to a simulated predator attack than turtles from areas with little or no fishing. In addition, our results showed that females waited longer to react after a simulated predator attack and were slower to self-right successfully compared to males. These findings reveal the intricate relationship among morphology, self-righting performance and antipredator behaviour.</p>","PeriodicalId":17600,"journal":{"name":"Journal of Zoology","volume":"328 4","pages":"369-383"},"PeriodicalIF":1.6,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148045489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected samples of bryophytes from glacial (the glacier ice surface and a medial moraine) and proglacial environments (the glacial forefield), as well as from glacier sediments (cryoconite) at Austerdalsbreen, Norway. The fauna was identified by applying a classical (microscopic) approach combining the knowledge of various taxonomic experts and a molecular (metabarcoding) approach.

The invertebrate diversity of the glacier mice comprised Tardigrada, Rotifera, Acari, Collembola, Coleoptera, Diptera, and unidentified Nematoda and Psocoptera. In total, we found 94 species, of which 39 were found in glacier mice from the glacier ice surface. Although the diversity of invertebrates in glacier mice was lower than in the proglacial environment, we identified specialists in glacier mice on ice such as the tardigrade <i>Fontourion glaciale</i>, the beetle <i>Helophorus glacialis</i>, and the springtail <i>Agrenia bidenticulata</i>. The composition of Rotifera overlapped between the glacial and proglacial environments, while it differed for other groups. Joint species distribution analyses revealed that Rotifera, Tardigrada, and Collembola commonly occurred in glacier mice on ice surface habitats, whereas the probability of Acari occurrence was highest in the proglacial environment. No major differences were observed in higher taxonomic group-based community compositions of invertebrates (alpha and beta-diversity indices) across ecosystems.
