(Summary) <p>The Japanese government has pledged to achieve carbon neutrality by 2050. To realise this goal, renewable solar, wind, hydro and geothermal power generation are now attracting attention. Wind power is expected to have great potential in Japan, and is likely to be promoted on land and sea areas. However, with the introduction of wind power generation throughout Japan, associated environmental conflicts are expected to increase. The main points of contention are noise, infrasound, landslides, water pollution, landscape aesthetics, the natural environment and birds, especially bird collisions and habitat abandonment caused by the construction of wind turbines in the habitat of rare birds of prey, such as the golden eagle <i>Aquila chrysaetos</i>, Hodgson's hawk eagle <i>Nisaetus nipalensis</i> and the white-tailed eagle <i>Haliaeetus albicilla</i>. Environmental conflicts are likely to increase as wind power projects are developed, to achieve the 2050 target. Therefore, the use of sensitivity maps should help prevent bird collisions and habitat abandonment. A sensitivity map shows where birds are likely to be negatively affected by the construction of wind power facilities, based on integrated information on the habitat of endangered bird species, migratory bird flyways, colony sites, overwintering areas, protected areas, etc. This review first explains the concept of a sensitivity map and describes its relation to environmental assessments. Then, we explain the features of various proposed sensitivity maps and discuss their appropriate resolution. Finally, we discuss the roles of sensitivity maps in future efforts to reconcile biodiversity conservation and the anticipated demand for renewable energy development, to attain the 2050 carbon-neutral target.</p> (Keyword) 空間解像度 / 再生可能エネルギー / mitigation / 戦略的環境アセスメント / ゾーニング / EADAS (Link to Publication Site) ● Publication site (DOI): 10.18960/hozen.2114 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390298820566700288 ● Search Scopus @ Elsevier (DOI): 10.18960/hozen.2114 (DOI: 10.18960/hozen.2114, CiNii: 1390298820566700288)

Negish, Tomoko Minagawa, Hideyuki Doi, Yoichi Kawaguchi and Yuichi Kayaba : Effects of sediment replenishment on riverbed environments and macroinvertebrate assemblages downstream of a dam, Scientific Reports, Vol.11, No.1, 7525, 2021. (Summary) Riverbeds downstream of dams are starved of sediment, impacting habitat structure and ecological function. Despite the implementation of sediment management techniques, there has been no evaluation of their conservational effectiveness; the impacts on high trophic level organisms remain unknown. This study examined the effects of sediment replenishment on riverbeds and macroinvertebrates in a dammed river before and after sediment replenishment. We evaluated the particle sizes of replenished sediments and the case material of a case-bearing caddisfly. We observed significant changes in macroinvertebrate assemblages before and after sediment replenishment, and between the upstream and tributary references and downstream of the dam. The percentages of Ephemeroptera, Plecoptera, and Trichoptera, and the number of inorganic case-bearing caddisflies downstream of the dam following sediment replenishment, were significantly higher than the upstream and tributary reference sites. The particle size of case materials used by case-bearing caddisfly corresponded to the size of the replenished sediment. Dissimilarity results after replenishment showed that assemblages downstream of the dam differed from upstream sites, although they were similar to the tributary sites. The dissimilarity between the tributary and downstream of the dam was the same as that between the upstream and tributary. Sediment replenishment was observed to reduce the harmful effects of the dam, and partly restore benefits such as increasing species diversity and altering community assemblages, similar to the effects of tributary inflows.

(Summary) <p>Offshore wind energy is a renewable energy source that offers an opportunity to reduce greenhouse gas emissions while increasing energy security. However, many ecologists have suggested that offshore wind farms may have severe negative impacts on wildlife, especially seabirds. Thus, balancing seabird conservation with human energy demands is necessary when developing wind farms. Bird sensitivity mapping is a powerful and practical tool that can determine turbine collision risk within specific areas; however, sensitivity maps have seldom been generated for seabirds. Focusing on the Slaty-backed gull (Larus schistisagus), a red-listed species that often collides with wind turbines, we determined factors affecting habitat selection with the goal of reducing negative impacts of offshore wind farms. We then generated a sensitivity map using habitat modeling. GPS loggers set to record at 5-minute intervals between June and August 2018 were attached to six Slaty-backed gulls residing in Ochiishi Bay, Nemuro Prefecture, Japan. A Gaussian mixed model indicated that habitat selection was related to food availability (as determined by sea surface temperature and chlorophyll a content) and distance to the nest site. Sea surface temperature and chlorophyll a content were positively related area visitation frequency of Slaty-backed gulls, whereas distance to nest site was negatively correlated. Moreover, area visitation frequency was unchanged when the distance from the nest site was > 25 km. The sensitivity map indicated that areas both near and far from nest sites with potentially abundant food resources were high-risk areas with respect to turbine collisions for Slaty-backed gulls. Based on these results, we advocate the use of sensitivity mapping to reduce interactions between offshore wind farms and seabirds, especially for species that often forage far from their nest sites.</p> (Keyword) Collision risk assessment / seabird conservation / renewable energy / wind turbine (Tokushima University Institutional Repository) ● Metadata: 115527 (Link to Publication Site) ● Publication site (DOI): 10.18960/hozen.1928 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1391412881271598592 ● Search Scopus @ Elsevier (DOI): 10.18960/hozen.1928 (Tokushima University Institutional Repository: 115527, DOI: 10.18960/hozen.1928, CiNii: 1391412881271598592)

(Summary) Global warming is causing the distributions of many species to shift towards higher latitudes or altitudes. The white-spotted char (<i>Salvelinus leucomaenis</i>), a cold-water adapted stenothermal fish, is potentially vulnerable to ongoing climatic warming. We therefore evaluated the extent to which the areas protected by national parks cover current and future potential habitats of <i>S. leucomaenis</i> under various climate-warming scenarios. Species distribution models using MaxEnt predicted that catchment area, slope inclination, distance to the river mouth, and estimated ground water temperature were key factors for potential habitats of anadromous and landlocked populations, and that 28.4% of potential habitats would be lost with a 3°C increase in the annual average air temperature. Potential habitats at lower latitudes, in particular, are likely to be affected, and most river basin habitats would disappear if the average temperature were to increase by 2°C. Although potential habitats in higher latitudes are less vulnerable to climate warming, the current national park system would not be able to protect these refuges. There is thus an urgent need for the development of conservation measures to mitigate the potential impact of global warming on white-spotted char habitats.

G (Environmental Research), Vol.73, No.6, II_373-II_377, 2017. (Summary)  We examined relationship between environmental factors and the density of a fleshwater snail, <i>Semisulcospira libertina</i>, which is main prey of a Genji firefly (<i>Luciola cruciata</i>) lavae at seven stations in Kawata River, Misato, Tokushima Prefecture. Moreover, we examined correlation between fleshwater snail density and observed number of Genji firefly. The results showed that the density of fleshwater snail was high on lentic site and positively correlated with water depth and rock size, while negatively correlated with the current velocity. River characteristics such as lentic, deep, and rocky substrate might be suitable for fleshwater snail habitat. Estimated densities of <i>S.</i> libertina were strongly correlated with the observed numbers of adult Genji firefly. To conserve Genji firefly, conservation of river environments for fleshwater snail habitats are also required.

(Summary) With rapid declines in global riverine biodiversity, conservation is needed on a nationwide scale. Since 1990, the National Census on River Environments (NCRE) has collected meaningful data on riverine organisms and environments in Japan. However, there are several issues with using the NCRE database for scientific studies. In this study, we summarised issues related to the NCRE database, and used the 3<sup>rd</sup> NCRE dataset (2001-2005) to evaluate nationwide trends in species richness and the rarity of fishes (primarily freshwater and diadromous fishes) and taxon richness and the rarity of benthic animals (aquatic insects and shellfishes). First, we summarised data quality (e.g. monitoring sites and season) and data formatting issues (e.g. site name and species name). Second, we mitigated these potential issues as thoroughly as possible and tested the relationships of species (or taxon) richness and rarity with latitude using generalised linear models. We found that species and taxon richness showed different latitudinal distributions between primarily freshwater and diadromous fishes and between aquatic insects and shellfishes. In contrast, rarities showed spatial congruence with species diversity, suggesting that more species and rare species could be conserved in the same regions.

(Summary) The Yoshino River, Japan, is rich in water resources, but simultaneously possesses high risk of flood disaster. River improvement works to reduce damage from the floods have been conducted which attain increase of the discharge capacity. On the other hand, local sediment deposition and scouring are growing concern by the repeated floods, decreasing of sediment supply and construction of river structure. In order to resolve these problems, it is necessary to understand the effects of natural and artificial impacts on the river channel. In this paper, the channel transition processes were studied in the Middle Yoshino River using aerial photo, morphology data. Natural and artificial impacts on those processes were evaluated from sandbar deformation, fluctuation of bed elevation and volume in low-water channel. As a result, sandbar deformation by the floods and revetment works was confirmed. The floods and dam construction affected fluctuation of river channel with the sediment deposition and scouring.

(Summary) This paper aims to propose concrete measures for the conservation of the mud loach (<I>Misgurnus anguillicaudatus</I>) in Sado Island of Japan, associated with the reintroduction of Japanese crested ibis (<I>Nipponia nippon</I>) that has a predilection to feed on the loach. The field survey was conducted at 80 sites on 7 rivers in the island in August 2007 and March 2008, in which the loach density and the micro-scale environmental factors (water depth [WD], degree of aquatic vegetation [AV], degree of riparian forest [RF], current velocity [CV], mud river bed [MB], concreted river bed [CB], and river bed pebble size [PS]) of the habitats were surveyed. Additionally, the macro-scale factors (paddy fields area [PA] and reservoirs area [RA] within a specific buffer circle) were also obtained using GIS software. The analysis using GLM and AIC showed that the AV (positive), MV (positive), CB (negative) and RA (positive), and AV (positive), MV (positive) and PA (positive) effect the loach density in August and March, respectively, indicating that the loach preferred the less artificial habitat surrounded by the paddy fields. The potential maps of the loach density were drawn by adapting the models on the rivers in the island: The loach density was especially high in the Kuninaka Plain that situated at central region of the island in both August and March, indicating the region was priority area for the conservation of the loach. In conclusion, removal of concrete revetment in the habitats and improvement of creek networks between rivers and landscape elements (paddy field and reservoirs) in the Kuninaka Plain would be the effective conservation measurements for the loach.

(Summary) In order to grasp the effect of the gentle slope revetment works to exert on the biodiversity at a tidal river, we surveyed at the tidal area in the Gokase River in Miyazaki Prefecture about the distributions of physical environments (ground levels, grain diameter and ignition loss of bed material) and the benthic communities at both of the soil-covered gentle slope revetment (A), and the vertical dry stone pitching revetment (b). As the results, the physical environments were similar in a transverse direction at the B section but the A section were successively varied. The kinds, and rare species of benthos, especially insects were rich at the A section rather than the B section. The results suggested that the gentle slope revetment works had improved biodiversity.

JSCE, Vol.53, 1189-1194, 2009. (Summary) The biological indicator should be developed in the ecoregion where biota is relatively identical. Furthermore, as stream biota widely varies from headwater to downstream, it is necessary to define segment based ecoregions where biota is longitudinally identical. In this study, we delineated segment based ecoregions for ten rivers belonging to the northwest Kyushu ecoregion based on the degree of similarity of the fish fauna. The northwest Kyushu ecoregion was divided into five segment based ecoregions. As a result, fish fauna was more clearly characterized by the differences in community structure between segment based ecoregions than those between watersheds. Moreover, distinguishing segment based ecoregions, enabled us to compare the integrity of fish fauna between watersheds, which had been previously difficult to examine.

(Summary) River ecosystem is spatiotemporally dynamic under frequent and intensive geomorphic disturbances, characterized by its fluctuating habitat availability. The species inhabiting there adapt themselves to the shifting habitat by developing various life-history strategies. In regulated rivers, however, suppressed disturbance and habitat dynamics threaten the disturbance-dependent communities. The recognition of important geomorphic perspectives is still in its infancy in conservation of river ecosystems in Japan. Riparian tree species have developed life-history strategies to increase the likelihood of arriving regeneration sites, where disturbance regimes are closely linked to the spatial and temporal availability of regeneration sites. River damming and channel modification severely diminish the critical function of geomorphic disturbance sustaining habitat diversity and abundance. Channel migration ceases in flow-regulated rivers, which may temporarily promote expansion of pioneer forest in the active channels. However, new geomorphic surfaces suitable for establishment of seedlings are no longer created because of altered peak flows and sediment supply, thereby threatening the recruitment opportunity and ultimate survival of their populations. Suppression of geomorphic disturbance also leads to the degradation of in-stream fauna. Channel straightening particularly simplifies geomorphic features of a river reach and diminishes longitudinal and lateral habitat diversity in its active channel. Flood control reduces inundation habitat and disrupts hydrologic connectivity between floodplain habitats (e.g., backwater and oxbow lakes), impacting fish and benthic invertebrates that require those habitats in their various life stages. A channel re-meandering experiment in the Shibetsu River, Hokkaido, demonstrates that the recovery of geomorphic dynamics can play significant roles in restoration of river ecosystems. Meandering reaches develop shallow edge habitat with low hydraulic stress along the inside of a convex, providing stable substrate for macroinvertebrate communities. Fallen trees provided by lateral erosion also promote macroinvertebrate colonization and become in-stream covers for fish communities. Geoecology in Japan as well as Europe and U.S. has long focused on vegetation pattern in alpine regions and has unexplored terrestrial and aquatic ecosystems in the vicinity of human activities. Knowledge in habitat dynamics and geomorphic processes is vital to ecosystem conservation and restoration. We believe that participation of geomorphologists is essential in future development of conservation and restoration strategies.

(Summary) 河川内の倒木は，治水上の問題や舟運の阻害要因となることから，世界中の河川で管理上の障害物とみなされ，排除の対象となってきた．しかし，1970年代以降，北米太平洋岸地域を中心とした多くの研究により，倒木が河川生態系に果たす重要な役割が強く認識されるようになった．そして現在では，アメリカ，ヨーロッパ諸国，オーストラリア等において，河川内への倒木の投入が水生生物の生息場を改善する手法として有効であると広く認められ，実践されている．本論では，河川生態系に及ぼす倒木の役割を概観した後，これまで多くの研究が行われてきたサケ科魚類と倒木の関係に焦点をあて，倒木の役割および倒木を使った生息環境改善について，海外と日本における研究事例をそれぞれ紹介する．ここで，海外の研究事例については既存の代表的な知見をまとめたのに対し，日本の研究事例については，海外で得られた知見と比較し，日本において重要となるであろう論点を整理した．また，北海道標津川下流部において国内で初めて実施された大規模な倒木投入実験におけるサクラマスの応答についても紹介する． (Keyword) サケ科魚類 / 生息場 / 倒木投入実験 (Link to Publication Site) ● Publication site (DOI): 10.20820/suirikagaku.51.6_60 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390282679518090752 ● Search Scopus @ Elsevier (DOI): 10.20820/suirikagaku.51.6_60 (DOI: 10.20820/suirikagaku.51.6_60, CiNii: 1390282679518090752)
