While the preferred habitats of moles—top predators in the soil food web—are well documented in open areas such as cultivated lands and grasslands, few studies have focused on mountain forests, where assessing mole abundance is complicated by thick layers of plant leaf litter and complex topography. Additionally, many monoculture conifer plantations in Japan are poorly managed, potentially resulting in compacted soil that is less suitable for moles compared to natural broad-leaved forests. Here, we aimed to quantify the relative abundance of the lesser Japanese mole (<i>Mogera imaizumii</i>) in the mountain forests of Yamagata, Japan, by carefully searching for mole tunnels along 29 census routes (unpaved mountain trails) over 7 months. Although tunnels were detected on most routes (75.9%) regardless of forest type, tunnel density (tunnels/km) was lower in cedar (<i>Cryptomeria japonica</i>) plantations than in natural oak forests. The variation in tunnel density was positively related to earthworm biomass, highlighting the importance of earthworms as a food source. Lower earthworm biomass was associated with either higher soil hardness or higher soil moisture; however, only soil moisture tended to be higher in plantations. As cedars are typically planted in moist environments, the reduced mole abundance in these plantations may be related to the specific soil conditions of cedar plantations. These results demonstrate that mole abundance varies significantly across forest sites in response to soil environments.</p>","PeriodicalId":11434,"journal":{"name":"Ecological Research","volume":"40 4","pages":"549-558"},"PeriodicalIF":1.7,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1440-1703.12548","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective was to evaluate macaque's feeding habits at the individual scale and to clarify the relationship between feeding habits and social factors, including age, sex, and social rank. The study population consisted of the Main group of Japanese macaques on Koshima Island. We collected 78 body hair samples and 29 food resource samples for isotopic analysis. The variability in carbon, nitrogen, and sulfur isotope ratios among individuals in the Main group has ranges of 5.5‰, 6.5‰, and 6.8‰, respectively. Furthermore, the Bayesian mixture model revealed that there were individual differences in the utilization of forest-derived (62.3%–90.5%), marine-derived (6.1%–27.6%), and human-derived (1.7%–23.4%) food resources, driven by the effect of sex, rank, and year. These findings particularly emphasize the utility of sulfur stable isotope ratios and demonstrate how the combined use of three stable isotope ratios enables effective analysis of the relationships between Japanese macaques and their food resources. Furthermore, our results provide a valuable opportunity for the advancement of future research that integrates stable isotope approaches with field investigations. This study not only highlights the applicability of sulfur isotope ratios as a tool for uncovering the use of marine resources by primates in other regions but also shows the potential of using isotopic techniques to distinguish human-derived resources, such as wheat, and to develop strategies for managing crop-raiding by macaques.</p>","PeriodicalId":11434,"journal":{"name":"Ecological Research","volume":"40 4","pages":"523-538"},"PeriodicalIF":1.7,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1440-1703.12547","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we tested the feasibility of the PAM for monitoring bird species and revealed some critical points to consider in improving or developing more widely applicable PAM. We conducted PAM in the subtropical forest landscape of Amami-Oshima Island, Japan, which harbors rich biodiversity (over 100 species), including endangered and/or endemic plants and animals. Nine endemic forest bird species were detected across recording locations. The effects of environmental factors on the four bird species were analyzed, excluding the five species that were commonly detected and did not require occupancy modeling. Different environmental factors influenced the occupancy probability of the four species examined according to their habitat preferences, which is consistent with previous studies. Our results suggest that the combination of PAM and occupancy model enables us to identify the bird's spatial occupancy pattern, associated environmental factors, and the important areas that should be protected for conservation.

The rate of climate change and anthropogenic impacts outpace our traditional observation tools' capabilities, underscoring the urgency for new assessment methods. Environmental DNA (eDNA; DNA traces released by organisms) metabarcoding, a non-invasive method widely developed over the last decade, represents a promising biomonitoring tool thanks to a large spatio-temporal coverage, high detection of rare species and its time and cost-effectiveness. However, capturing fish diversity using eDNA requires genetic reference databases, currently lacking. Improving reference databases relies on opportunistic sampling enabling the reporting of sequences for new species. The data provided here consists of barcoding 86 species of fishes over the 12S mitochondrial DNA gene. We generated 156 sequences of the mitochondrial 12S gene adapted to the “Teleo” barcodes from fishes sampled in the Bay of Biscay (BoB; Northeast Atlantic, France) between 2017 and 2019. In addition, we provided each individual the barcode details (Genbank accession number, chromatograms), a photograph, 5 ecomorphological measures and 11 life-history traits documenting ecological functions (e.g., dispersion, habitat use, diet). Furthermore, we provided the sampling metadata (e.g., date, time, gear, coordinates, depth) and environmental variables measured in situ (e.g., conductivity, water/air temperature). This data set is valuable to improve the Northeast Atlantic eDNA genetic database, thus helping to better understand the effects of environmental forcing in the BoB, a transition zone housing mixed assemblages of boreal, temperate, and subtropical fish species susceptible to display variability in functional traits to adapt to changing conditions.

Although past distributions have been reconstructed for several woody species in Japan, few studies have focused on the cold-adapted woody species that survive in the Japanese Archipelago. <i>Betula costata</i> Trautv., a species considered a glacial relict, is a common canopy tree in the cool-cold temperate forests in Northeast Asia.

We tested the working hypothesis that <i>B. costata</i> was once abundant in the Japanese Archipelago during the LGM. However, postglacial climate warming caused it to become a disjunct and relict. Two types of SDMs, Maxnet and Random Forest, predicted suitable habitats for the species with three time periods: The LGM, mid-Holocene, and present. The resulting maps of suitable habitats during the LGM showed extensive distribution across continental Asia and the Japanese Archipelago.

Analysis of the reasons for adoption suggested that the temporal change in adopted flower species was related to the increasing emphasis on species with an explicit local context, especially those with instrumental value to the city.
