ABSTRACTHome range size estimation is an important basis for developing effective conservation strategies and provides important insights into the study of animal behavior and spatial ecology. We analyze home range variations and the fitfulness of estimation methods on Chinese gorals (Naemorhedus griseus) living at a cliff landscape with GPS tracking data. We report annual, seasonal, and monthly home range sizes of five female Chinese gorals tracked from February 2015 to September 2018. We found variations existed in 95% seasonal home range sizes among estimation methods. We recommend that the α-LoCoH model be used in home range estimations, as this model appeared to more accurately reflect animal locations within the steep cliff habitat in our study area. Furthermore, more animals should be GPS tracked to ensure the validity of any interpretation concerning their home range size in a rugged habitat. This study was the first conducting home-range GPS tracking of Chinese gorals in their northern distribution range. Additionally, our findings provided previously unknown information regarding the home range traits of this endangered species, and they may contribute to the development of effective conservation strategies.KEYWORDS: Chinese goralhome rangeminimum convex polygonkernel density estimationα-local convex hull AcknowledgementsWe would like to extend our gratitude to all the staff in the Inner Mongolia Saihanwula National Nature Reserve for their valuable support in helping us capture and collar the animals, as well as maintaining the habitats.

ABSTRACTSoil erosion, which involves the degradation of the physical and chemical properties of soil, is a major threat to the soil environment. Although the effects of soil erosion on the physical or chemical properties of forests have been studied, little has been reported on the soil microbial community, which is likely to affect forest ecosystems. This study aimed to elucidate how the microbiome changed with the soil environment accompanying soil erosion in cool temperate mixed forests in Southern Japan, where soil erosion has been accelerated by the increased population of sika deer. We investigated the soil microbial communities of the different soil erosion intensities at three forest sites. In prokaryotic communities, diversity indices were increased with the sum of the height of exposed roots (SUMH), an index of soil erosion. In fungal communities, the relative abundances of plant pathogenic and wood saprotroph fungi were increased as SUMH increased and those of symbiotrophs and ectomycorrhizal fungi were increased with humus organic matter content, suggesting that the difficulties in establishing plants would be increased as soil erosion progressed because of the changes in the composition and function of fungal communities in eroded areas. Moreover, soil fungal communities had a more complex co-occurrence network than that of prokaryote, suggesting that the effects of soil erosion on fungal network is smaller than those on bacterial network. Changes in the soil environment induced by soil erosion altered the microbiomes in the deeper layers of the soil and had different effect on prokaryotes and fungi.KEYWORDS: Japanese beech (Fagus crenata)Microbial diversityMultifunctionalitySoil lossSymbiotrophic fungi Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Author contributionsA.K. and Y.T, conceptualized, designed, and administrated this project, and lead the funding acquisition of this study; F.C., A.K., M.O. and Y.T. conducted the sample and data collections and raw data curation; F.C. and Y.T. designed and analyzed the study data and prepared the draft; all authors reviewed manuscript critically and wrote the manuscript.Data availability materialsAll the raw sequence data of the prokaryotic 16S rDNA and eukaryotic 18S rRNA genes were submitted in the Sequence Read Archive of DDBJ database under the accession number DRA015283.Geolocation information32°22’N, 131°11’E,32°22ʹN, 131°08ʹE,32°09’N, 130°55’ESupplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/13416979.2023.2265006Additional informationFundingThis work was financially supported by Nippon Life Insurance Foundation (2021-03), Leading Initiative for Excellent Young Researchers from the Ministry of Education, Culture, Sports, Science and Technology, Japan (Grant Number JPMXS0320220123), and

ABSTRACTGrowth data obtained from Chamaecyparis obtusa growing at 28 progeny test sites in the Kanto breeding region of Japan were analyzed to estimate the genetic parameters and genetic gains. Specifically, the data were used to estimate stem diameter at breast height (DBH), tree height (TH), and stem volume in order to assess the feasibility of breeding, and differences in genetic parameters and genetic gains associated with growth traits based on age and climatic conditions were clarified. The median values of narrow-sense heritability for DBH and TH across all ages ranged from 0.229 to 0.263 and from 0.201 to 0.433, respectively. Based on the efficiency of improvement (genetic gain per year), it appears that the most efficient selection for DBH and stem volume would be at one-third of the improvement target age (set to 30 years in the present study). We analyzed the variation of narrow-sense heritability and age trends of those among three groups of test sites exposed to different climatic conditions. Age and group × age interaction were shown to have significant effects on the narrow-sense heritability of TH and volume and that of DBH and volume, respectively. However, no significant effects of group × age interaction were detected on the efficiencies for gain per year of all traits, implying that this parameter might not be affected by climate conditions. Therefore, it was suggested that early selection is possible with almost equal efficiency in all climate groups.KEYWORDS: Climate conditionheritabilitygenetic correlationgenetic gain AcknowledgementsStaff from the National Forests, the Prefectures and Forest Tree Breeding Center (FTBC), and the Forestry and Forest Products Research Institute established, maintained, and investigated the progeny test sites used in this study.

ABSTRACTConversion of old-growth forests to managed forests reduces the amount and variety of dead wood, particularly large snags (standing dead trees) are disappeared. Therefore, organisms that rely on large snags are considered to be severely affected by forest practices that convert old-growth forests to managed forests. We examined the effect of snag characteristics (diameter, bark cover, and decay gradient) on longicorn beetle (Cerambycidae) assemblages to search for species that prefer large-diameter snags in two old-growth remnants in a cool-temperate mixed forest and a sub-boreal conifer forest in Hokkaido, Japan. We collected beetles using window traps attached to conifer snags belonging to genus Abies and Picea and evaluated how snag characteristics affected beetles that feed on conifers with considering spatial autocorrelation. Species richness and total abundance were not associated with any of the snag characteristics. However, permutation tests in redundancy analysis revealed that snag diameter and bark cover affected species composition in the mixed forest, while only snag diameter had a significant effect in the conifer forest. Two (Macroleptura regalis and Prionus insularis insularis) and one (Sachalinobia koltzei) species preferred large-diameter snags in the mixed forest and the conifer forest, respectively. These species should be used as conservation targets to reduce the impacts of forest practices on saproxylic beetles. In contrast, one species (Molorchus minor fuscus) preferred small-diameter snags in the conifer forest. To conserve species that rely on large snags, we should maintain large snags in harvesting operations and retain large living trees for the future recruitment of large snags.KEYWORDS: Community analysisdead woodforest practiceinsect conservationspatial autocorrelation AcknowledgementsWe thank S.

ABSTRACTIn the age of big data, social media’s influence on on-site landscape experiences is growing, and the relationship between on- and off-site landscape planning and management is becoming more important. The study’s objectives were: 1) to identify scenic hotspots based on on-site visitor experiences, 2) clarify landscape preferences and attractiveness based on photographs taken at scenic hotspots, and 3) examine similarities and differences between Japanese and Korean visitors in terms of landscape preferences and attractiveness. The data were collected using geotagged visitor employed photography from 153 visitors to the Takao Quasi-National Park in Japan were used to understand off-site appreciation, and compare Japanese and Korean visitors’ experiences. Photo-based questionnaires were completed by 42 Japanese and 40 Korean respondents. We collected 1,645 geotagged photographs, and performed a GIS analysis with network-based kernel density estimation to identify scenic hotspots. The data extracted from the photo-based questionnaire were used to analyze the relationship between on-site and off-site experiences, as well as similarities and differences between the Japanese and Korean participants. The data were analyzed using means, Welch’s t-test, Wilcoxon sum-rank test, Pearson’s correlation analysis, and Kendall’s correlation analysis. The results identified nine scenic hotspots, and revealed that the photographs that the Japanese visitors preferred to take would not necessarily attract tourists, nor were they the same as the scenic spots and objects the Korean visitors found attractive. As international tourism expands, cross-cultural research on on- and off-site experiences and preferences has become increasingly important for forest landscape management and sustainable tourism.KEYWORDS: Landscape perceptionlandscape preferencenational parkGISgeotagged visitor employed photography AcknowledgementsWe would like to thank the 153 participants and 82 respondents who joined in our research.Disclosure statementNo potential conflict of interest was reported by the author(s).Geolocation informationJapanSupplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/13416979.2023.2257456.Additional informationFundingThis work was supported by the JSPS [14J05265].

However, the effects of exponential fertilization under varying fertilization levels on seedlings’ growth, nutritional status, and nonstructural carbohydrates (NSC) are poorly understood. We employed Armand pine (Pinus armandii) seedlings to investigate the responses of growth, nutrients (nitrogen, phosphorus, and potassium) in seedlings, and NSC in organs to varying exponential and conventional fertilization levels. Shoot height, root collar diameter, and biomass increased and then declined with the increased fertilization levels. At high fertilization levels (≥300 mg seedling−1), the seedings accumulated more biomass in exponential fertilization than in conventional fertilization. The exponentially fertilized seedlings contained more concentrated nitrogen, starch, and NSC than the conventionally fertilized ones. Vector analysis revealed that conventional fertilization of 200 mg seedling−1 or exponential fertilization of 300 mg seedling−1 could induce luxury consumption. NSC was closely related to the nutrient states. With the increased fertilization level, regardless of the regime, soluble sugar concentrations in roots and needles trended toward declining with changes in the nutrient supply from deficiency to sufficiency and then increased with the changes from sufficiency to toxicity. Meanwhile, starch and NSC concentrations in roots and needles increased with the changes in the nutrient supply from deficiency to sufficiency; the concentrations in roots decreased with the changes from sufficiency to excess. Exponential fertilization at high levels did not only promote seedling growth but also induced seedlings to reserve more nutrients and NSC, which could improve afforestation success.

The health status of the Moso bamboo forest could affect the economic value, ecosystem functions, and long-term sustainable management. However, there are still deficiencies in the scientific recognition and accurately assessment for the health status of the Moso bamboo forest. Using an index system to quantitatively assess the health of Moso bamboo (Phyllostachys edulis) forest can provide an intuitional recognition for the status of Moso bamboo forest. Here, the health assessment index system of the Moso bamboo forest was established by literature collection, Analytic Hierarchy Process (AHP), and expert questionnaire. The health index of the Moso bamboo forest was calculated by the comprehensive health index. The practicability and feasibility of the health assessment index system were then verified by the Moso bamboo forest in Anhui and Fujian provinces of China. The health index of the Moso bamboo forest in Anhui and Fujian provinces ranged from 0.50 to 0.83. The health index of the Moso bamboo mixed forest generally performing higher than that of the pure Moso bamboo forest. Only 2.35% of the Moso bamboo forest health index scored higher than 0.80, whereas 22.35% scored lower than 0.60. These results suggested that the health status should be improved in most of the Moso bamboo forest. The health assessment index system provides an important tool to guide Moso bamboo forest resource management and prioritize scientific research.
