PAM is expected to be one of the most efficient methods for assessing species distribution and examining the factors affect it, helping identify important areas for biodiversity conservation and inform the management plan. 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. PAM is a relatively low-cost and non-invasive method that can be applied in various monitoring of biodiversity conservation areas.</p>","PeriodicalId":11434,"journal":{"name":"Ecological Research","volume":"40 4","pages":"491-504"},"PeriodicalIF":1.4,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. However, <i>B. costata</i> is rare and has a disjunct distribution in the Japanese Archipelago, and the reasons for its rarity and disjunction in Japan remain poorly understood. Therefore, we investigated the distribution of <i>B. costata</i> in Northeast Asia since the last glacial maximum (LGM; between ca. 27,000 and 19,000 years ago) using species distribution models (SDMs). 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.

Here, we focused on the “city flower,” an official symbolic species of Japanese cities, as a new proxy for measuring governmental attitudes toward biota and its services. We aimed to capture temporal changes in the awareness of species with locally relevant value at the city government level by examining the changes in city flowers over more than half a century. Data from the official websites of municipalities, including the names, the adoption years, and the reasons for adoption, revealed two major periods of adoption, with a notable increase in species diversity in and after 1993. This increase could be attributed to a recent reduction in bias toward popular flowers and growing interest in alternative, less popular flowers. 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. Our findings indicate the tendency for local governments to increasingly recognize their biocultural backgrounds and the ecosystem services of plants within their regions.

We present the largest freely available EcoPlate dataset for planted forests in Japan, comprising data collected from a network of 74 planted forest sites (114 plots) in regions ranging from cool-temperate to subtropical. The EcoPlate is a 96-well microplate that contains three sets of 31 “response wells” with different carbon substrates. The utilization of each carbon substrate by the microbial community is quantified based on the color development of the well during incubation, providing a multifunctional index of the soil microbial community. Soil properties (water content, carbon, nitrogen, the carbon/nitrogen (C/N) ratio, and pH) essential for interpreting the EcoPlate results were also analyzed. Using a standardized protocol, soil was sampled between July and November 2021. A preliminary principal coordinate analysis (PCoA) was performed on the temporal integration of color density using the 31 substrates.

Additionally, we propose a numerical procedure to aggregate rankings and determine EV. Our study took place in a highly biodiverse neotropical cloud forest in western Mexico. Biodiversity was assessed through evenness, vulnerability by counting threatened species, fragmentation based on tree functional traits, connectivity by tree dispersal syndrome and successional behavior, and resilience from tree species' information and material legacies. To reveal similarity patterns among plots regarding the criteria and EV, we used nonmetric multidimensional scaling with permutational multivariate analysis of variance. To assess EV estimation reliability, we used altitude and azimuth as predictors through generalized additive models. The methodology unveiled that plots with the highest EV do not necessarily possess superior ecological properties (biodiversity and/or vulnerability) or structural and functional features (fragmentation, connectivity, and/or resilience), thus demonstrating the importance of including all criteria in the assessment and avoiding the use of a single criterion. Results showed that cloud forest plots with the highest EV were at an altitude of 1900–2200 m asl, facing southeast and northwest orientations.
