We report monitoring data of 45 forest plots (average area 0.69 ha; range 0.0325–6.25 ha) at 27 sites in Japan. These plots are situated within 32.38° N to 43.36° N and at elevations ranging from 8 to 2453 m above sea level. The forest plots include both old-growth and secondary forests, and cover various forest biomes, such as warm-temperate evergreen forests, temperate deciduous broadleaved forests, and boreal or sub-alpine coniferous forests. In each plot, all living trees and lianas larger than a certain minimum size (typically 15 cm stem girth at breast height) were repeatedly measured and survival and recruitment of stems were recorded over 5–40 years (average 17.3 years).

Impacts of non-native plants and animals, but not microorganisms and fungi, on terrestrial and aquatic (freshwater and marine) environments were included in this review. Most of the literature reviewed consisted of published articles, plus a few book chapters, dissertations, theses, and reports. We found 1003 records of ecological and economic impacts (970 negative and 33 positive) caused by 239 different species, as well as effects on people's well-being. Understanding and assessing all ecological interactions of IAS in nature, as well as evaluating their contributions to humans, can be a complex task. However, the current scientific evidence from Brazil suggests that negative impacts of IAS are far more common than positive impacts, highlighting the importance of avoiding novel introductions. From a conservationist perspective, the simple presence of IAS may cause the negative impact of changing the original structure and processes of nature. This is of special concern in megadiverse countries like Brazil, where interactions among species are multiple and complex. Therefore, we believe this extensive review is an important contribution to the national knowledge of IAS and the improvement of global databases, which must be periodically reviewed.

This study aimed to reveal the long‐term variation in stream water chemistry in approximately 40 forested small watersheds in the northern Kanto region, based on 3 surveys conducted in 1991–1992, 2006–2007, and 2022. The factors influencing each dissolved element were investigated. Regarding long‐term variations in stream water chemistry, relatively stable concentrations of cations (Ca<jats:sup>2+</jats:sup>, Mg<jats:sup>2+</jats:sup>, K<jats:sup>+</jats:sup>, and Na<jats:sup>+</jats:sup>) and SiO<jats:sub>2</jats:sub> were observed. However, the concentrations of anions (Cl<jats:sup>−</jats:sup>, , and ) decreased due to the improvement in the atmospheric environment and the diminishing effect of fertilization. Furthermore, the recent increase in stream water pH was attributed to an increase in bicarbonate (), compensating for the decrease in anion concentrations relative to cations. Geology was the most significant factor for inter‐watershed variations in cations and SiO<jats:sub>2</jats:sub>, and this influence remained relatively constant over 30 years. Forest practices, especially fertilization, had a significant effect on Cl<jats:sup>−</jats:sup> and , and contributed to higher concentrations in the fertilized watersheds than in the non‐fertilized watersheds over the 15 years following fertilization. Sulfate deposition was a significant influencing factor for , and the concentration fluctuated under long‐term variations in deposition over the past 30 years. Despite substantial acid deposition in the study area, the absence of stream water acidification could be attributed to the abundant cation supply from bedrock and volcanic ash, which underwent weathering processes.","PeriodicalId":11434,"journal":{"name":"Ecological Research","volume":"34 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140116949","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 hand-corer consisted of two L-shaped aluminum angles that were driven separately into the soil to reduce friction between the corer wall and the soil. This allowed for soil cores to be collected with less compression than with traditional corers. The corer is easily made, inexpensive, lightweight, and easy to carry. The degree of compression of soil cores collected at a depth of 20 cm from various montane forests in Japan was usually less than 10% (collected core length >18 cm); although, more compression occurred in soil with a higher air content. The degree of compression of soil cores collected from urban forests was lower than that in montane forests. When the two-stage sampler was compared with a tube-type sampler in a Japanese cedar (<i>Cryptomeria japonica</i>) forest, the compression degree of a soil core collected with the two-stage sampler was a quarter that of the tube-type sampler. The collection of less-compressed soil cores will allow for reconstruction of a more accurate linear depth distribution of contaminants. To demonstrate this, we investigated the vertical distribution of Pb, Sb, and radioactive <sup>137</sup>Cs in soil cores collected from conifer plantations on Mount Tsukuba, Japan, in April 2011. The migration centers of anthropogenic Pb, Sb, and <sup>137</sup>Cs were positioned at 7.9, 7.5, and 3.3 cm from the ground surface, respectively.

On the western side of the Japanese Archipelago, boreal forest and non-forest vegetation were dominant during the last glacial period; subsequently, temperate forests expanded, and open vegetation (e.g., grasslands) decreased. Such vegetation shifts can result in incongruent phylogeographic patterns among temperate forest and grassland species; however, few phylogeographic studies have investigated this hypothesis. Here, we evaluated the phylogeographic structure of two related <i>Geranium</i> species that occur in grassland (<i>Geranium krameri</i>) and temperate forest (<i>Geranium shikokianum</i>) habitats using chloroplast genome sequencing and nuclear genome-wide single-nucleotide polymorphisms genotyping. The phylogeographic structure was stronger for the temperate forest species than the grassland species, despite its currently scattered distribution for grassland species. The observed patterns indicate that the phylogeographic histories of these species were influenced by their habitat configurations since the last glacial period. During the ice age, grasslands in Japan were much more widespread than today; this would have enabled the grassland species to form a continuous distribution, leading to low divergence among regional populations. In contrast, the significant genetic divergence within the forest species can be attributed to the glacial isolation of regional populations.
