    There is a long history of humans either intentionally or accidentally moving plant species to areas outside of their native ranges. In novel environments, populations of many of these plant species exhibit explosive population growth and spread, in part due to the absence of coevolved enemies such as herbivorous insects. However, over time such enemies can ‘catch up' with their host and re‐establish host–herbivore relationships. Though this phenomenon has been documented in several systems, little evidence exists on how this re‐assembly of enemies results in increased levels of herbivory. In this study we focus on the case of black locust Robinia pseudoacacia, a sparsely populated tree species when growing on undisturbed sites in its limited native range in the eastern USA but a highly invasive species, especially in disturbed environments, in most temperate world regions. We recorded folivore damage on invasive populations in five continents, including both native and invaded portions of North America. Here, we investigated 1) how total foliage damage and damage caused by different groups of folivores differs among regions; 2) how seasonal development of folivore damage differs among regions; 3) how folivory varies with distance from the native range within North America; and 4) how the number of recorded specialist folivores correlates with the amount of folivory. We observed strong differences among regions in the amount and type of folivore damage, with the native range experiencing the highest damage, especially that caused by the native chrysomelid beetle Odontota dorsalis, which is limited to the native and invaded North American range of R. pseudoacacia. Among world regions, total folivory is negatively associated with the distance from the native range and positively associated with the number of established R. pseudoacacia specialist folivore species, supporting the hypothesis that global patterns of herbivore invasions are associated with diminished enemy release.

    ワサビ(Wasabia japonica)は、アブラナ科ワサビ属に属する日本料理に欠かせない植物である。多年生植物であり、1年を通して葉を落としながら新しい葉に生え変わることを繰り返すため、通年出荷が可能な作物である。基本的に重量が重く大きいものほど単価は高くなる傾向があり、その他辛味や風味が良いもの、くびれがないものや色合いが良い物ほど品質が良いとされている。品質が悪いものは加工食品に利用され、1あたりの重さが100gを上回るようなものは高級料亭用に取引される。ワサビは栽培方法によって沢ワサビと畑ワサビに分類されるが、いずれも生育時に窒素やカリウム、石灰などを多く吸収する。よってそれらを豊富に含む流水が利用できる地域では一般的に沢ワサビとして栽培され、水量が少ない地域ではそのまま耕土に植える畑ワサビが栽培される。沢ワサビの方が形、色合いや辛味などが畑ワサビを上回るため、市場価値は沢ワサビのほうが高い。沢ワサビは主に長野や静岡など山間部の多い地域74橋本敏一・松野裕・八丁信正・河内香織で栽培されている。沢ワサビの栽培に必要な水は豊富な養分に加え、水温が8~19℃の間であり、12~13℃の問が最適とされている。もし水温が8~19℃の範囲を外れると生育停止がおこる。また水温が高くなると墨入病や軟腐病などの病害が発生するので栽培の際には水温に注意する必要がある。ワサビは半陰性の植物で直射日光に弱く、環境によっては栽培時に遮光するなどの工夫が必要となる。植えつけの時期は生育停止するような夏期や冬期を避け、春植え(3~5月)もしくは秋植え(9~10月)が一般的で、秋植えの方が生育がよいとされる。

    Most studies of the effects of litter mixing have focused on decomposition in mixtures of senescent leaves of different plant species. In temperate forests, substantial quantities of green leaves fall in spring and summer, and previous research has shown that stream detritivores can benefit from the combined use of senescent and green leaves. We conducted a litterbag experiment to test the hypothesis that mixtures of senescent and green leaves of different species decomposed more rapidly, mediated by increased detritivore colonization, than leaves of each type in isolation. The observed abundances of 2 detritivore species, the amphipod Sternottioera rhyaca and the caddisfly Lepidostoma complication, were 3 to 6x higher in mixtures of senescent oak and green alder leaves than expected based on litter patches consisting of each species alone. Lepidostoma complication also responded positively to mixtures of senescent oak and green maple leaves, but S. rhyaca did not. These results verify that caddisfly behavior can reflect benefits gained from the combined use of senescent and green leaves. In contrast, the extent of the advantage to amphipods depends on the specific combination of senescent and green leaves. Despite the synergistic effect of mixed senescent oak and green alder leaves on detritivore colonization, observed leaf mass loss in mixtures was not higher than expected. Changes in the chemical properties of senescent oak and green alder leaves in mixtures might decrease feeding rates of detritivores because of preferential or compensatory feeding. Mixtures of senescent and green leaves did not alter leaf decomposition of each component in spring and summer, but might enhance leaf decomposition in autumn and winter by augmenting detritivore populations.

    In forested streams, surrounding riparian forests provide essential supplies of organic matter to aquatic ecosystems. We focused on two pathways of particulate organic matter inputs: direct input from upper riparian forests and indirect lateral input from bank slopes, for which there are limited quantitative data. We investigated the inputs of coarse particulate organic matter (CPOM) and carbon and nitrogen in the CPOM into the uppermost reaches of a headwater stream with steep bank slopes in Hokkaido, Japan. CPOM collected by litter traps was divided into categories (e.g., leaves, twigs) and weighed. Monthly nitrogen and carbon inputs were also estimated. The annual direct input of CPOM (ash-free dry mass) was 472 g m(-2), a common value for temperate riparian forests. The annual lateral CPOM input was 353 g m(-1) and 941 g m(-2) when they were converted to area base. This value surpassed the direct input. Organic matter that we could not separate from inorganic sediments contributed to the total lateral input from the bank slopes (124 g m(-1)); this organic matter contained relatively high amounts of nitrogen and carbon. At uppermost stream reaches, the bank slope would be a key factor to understanding the carbon and nitrogen pathways from the surrounding terrestrial ecosystem to the aquatic ecosystem.

    The environmental factors influencing the abundance of fluvial larvae of the lamprey Lethenteron japonicum was studied in a tributary of the Ishikari River, central Hokkaido, Japan. We also conducted their food requirements by laboratory rearing experiment. The abundance of larvae and environmental parameters (Water temperature, Water depth, Water velocity, pH, Dissolved oxygen, Conductivity, Turbidity, Substrate hardness) were measured in one-meter-square quadrats. The larvae were captured using an electro-fisher and separated into two size classes (1-5 cm and 5-15 cm). The relationships between abundance and environmental factors were analyzed using generalized linear mixed models for each size class. The environmental factors that predicted the patterns of abundance of the two sizes of larvae differed for each size class. The abundance of larvae in the large size class was positively correlated with substrate hardness and dissolved organic matter (DOM), while that of the small size class was positively associated with substrate hardness, substrate composition (Silt), and current velocity. Sub-yearling larvae were also collected and reared for two months in the laboratory to observe their feeding preference by adding different foods. Their food uptake ratio was determined using stable isotope analysis. By the rearing experiment, the larvae which were given fallen leaves had significantly greater increases in wet mass and body length, as compared to the larvae which were given algae. The stable isotope analysis indicated that the larvae can take up nutrients from fallen leaves. We concluded that lamprey larvae change their habitat requirements with growth stage, and fine substrate containing fine organic matter is a significant microhabitat for fluvial larvae lamprey.

    We investigated the distribution patterns of senescent and green leaf litter patches on a streambed to evaluate the hypothesis that the different immersion times of senescent leaves in long-term benthic storage and newly retained green leaves affect streambed distribution patterns in summer (June, July, and August). We counted all the leaf litter patches in the streambed of the study reach, comparing the physical condition of patches and classifying the trapping obstacles associated with each patch type. The distribution patterns of senescent and green leaf litter patches differed. Green leaf litter patches were more numerous at every sampling date, with most trapped by cobbles, whereas senescent leaf litter patches were retained by twig obstacles, backwaters, and cobbles. In June and July, senescent leaf litter patches were located in significantly deeper stream areas than were green leaf litter patches. The distribution of senescent leaves would be primarily determined during spring snowmelt-driven floods. We speculate that senescent leaves were originally located at the edges of pools in the main flow pathway of the channel, which overflowed in the floods. We conducted flume experiments to clarify the transport characteristics of senescent and green painted maple and manchurian alder leaves in the water column. Our hypothesis was that the transport characteristics of each leaf type differ when they first enter the water, because of differing leaf properties. The flume experiments showed that duration of surface flotation differed for senescent and green leaves and for the two tree species. These differences in the duration of leaves on the streambed and in the floating time of green leaves of different trees ensure varied food resources for macroinvertebrates in various physical conditions.

    森林域から河口域に流下した粗大有機物が、沿岸に生息するトンガリキタヨコエビ(Anisogammarus pugettensis)の隠れ場所や食物資源としてはたす役割を明らかにするために飼育実験を行った。1、粒径と量の異なる落ち葉だまり内において、クロガシラガレイ若齢魚を捕食者として24時間後のトンガリキタヨコエビの生残率を測定した。ヨコエビの生残率はどの粒径においても量が多い場合に最大であった。2、落葉と海藻(ホソメコンブ)を食物資源としてトンガリキタヨコエビの飼育実験を行い、成長速度と炭素安定同位体比を調べた。ヨコエビの安定同位体比からは、海藻に加え、体内に落葉も取り込んでいる事が示された。トンガリキタヨコエビは、落葉を主に隠れ場所として利用するが、予備的に食物資源としても利用していると推察され、河口域の落葉だまりは、低次消費者の涵養の場として重要な役割を果たしていると考えられた。

    We conducted a decomposition experiment using green and senescent maple and alder leaves in a coastal headwater stream in Hokkaido, northern Japan, during June and July 2000. We estimated whether shredder colonization on the leaves and leaf breakdown differed between green and senescent leaves during the experimental period. Late-instar Lepidostoma complicatum (Trichoptera) and Sternomoera rhyaca (Amphipoda) were the predominant shredder taxa among the macroinvertebrates that colonized litterbags. There was no significant difference in shredder colonization between green and senescent leaves although we found a significant difference between maple and alder leaves. The colonization patterns of large individuals of L. complicatum and S. rhyaca differed from those of small individuals. All decomposition coefficients of green and senescent leaves were high. During the experiment, decomposition was significantly faster in maple than in alder leaves, although no significant difference was found between green and senescent leaves. However, the fragmented nitrogen portion was higher in green leaves than in senescent leaves during the experiment. Higher nitrogen release (2-2.5 times more) as particulate organic matter in green than in senescent leaves indicates that green leaves may be a potentially valuable food resource for other macroinvertebrate collector-gatherer species.

    The brackish waters along the Hokkaido coast contain a mixture of plant material of both marine and terrestrial origin that provide food and habitat sources for many macroinvertebrates. Field and laboratory experiments were used to investigate the amount of breakdown of seaweed (kelp) and terrestrial oak leaves (green, senescent, and stream-water soaked ('conditioned')). In addition, the consumption and growth rates of Anisogammarus pugettensis were compared for the different leaf treatments. The breakdown of kelp was greater than that of terrestrial leaves. Among the three types of oak leaves, the amount of breakdown of green leaves was smallest and the breakdown of conditioned senescent oak leaves was 1.5 times greater than that of senescent leaves. Conditioning of leaves in fresh water enhances leaf decomposition in brackish water. The growth rates of A. pugettensis were similar and fastest when fed seaweed and a seaweed-leaf mixture (0.035 +/- 0.009 and 0.043 +/- 0.013 mg mg(-1) day(-1), respectively). The rapid colonisation of oak, despite its low nutritional value, suggests that leaves are important as a habitat, rather than as a food resource. Availability of both seaweed and terrestrial leaves as food resources and habitat would yield benefits for seawater-inhabiting macroinvertebrates.

    The effects of salmon carcasses on dissolved nutrients, epilithic production, leaf decomposition rates. and aquatic invertebrates were examined using 10-m-long, artificial channels fed by an adjacent natural stream in Hokkaido, northern Japan. Bags containing maple leaf litter were placed in nine channels, each of which was assigned to one of three treatments with three replicates, for 6 weeks in fall 2002. The three treatments were: (1) salmon carcasses+invertebrates, (2) invertebrates only. and (3) control (no salmon carcasses or invertebrates added). Nutrient concentrations, biomass of epilithic algae (chlorophyll), leaf weight loss, abundance and biomass of invertebrates in the leaf packs were compared among the three treatments at 14, 27, and 40 days after the beginning of the experiment. The NH4+ in stream water and chlorophyll concentrations of epilithic algae were higher in the salmon treatment than the other treatments, and the maple leaves decomposed faster in the salmon treatment than in the other treatments. Moreover. the N content of the leaves was highest and the C/N ratio was lowest in the salmon treatment. although not significantly so. The abundance and biomass of the dominant leaf-shredding invertebrate Goerodes satoi did not differ between the first two treatments. However, the stable N isotope ratio in G. satoi was nearly 3 parts per thousand higher in the salmon treatment, suggesting that around 20% of salmon-derived N was taken up by this shredder. Our results indicate that salmon carcasses affect stream ecosystems directly by enhancing primary production, indirectly by accelerating woody leaf decomposition, and finally by incorporating into the food web primary consumers that utilize fertilized woody leaves.

    1. Freshly fallen green leaves and flowers of terrestrial plants enter temperate streams in spring and summer, when senescent leaf litter is often scarce. These resources appear to provide good supplementary food for macroinvertebrate shredders, but have some potential shortcomings as food or case material for caddisflies. 2. To compare suitability of green leaves or flowers and senescent leaves for the growth and development of stream shredders, we reared the caddisfly Lepidostoma complicatum in the laboratory with treatments that provided larvae with senescent (oak) and green (oak or maple) leaves separately, and also together, in case the combined use of both types of leaf may benefit the shredder. 3. Larvae supplied with green leaves alone grew at 65% of the rate of those provided with senescent leaves alone, due to their lower consumption rate. No individuals given green leaves alone developed into adults, whereas 70% of the individuals given senescent leaves alone did. Green leaves may inhibit larval consumption due to their high phenol content, or they may be unsuitable for case material because they are less tough than senescent leaves. 4. Larvae supplied with both senescent and green leaves (or flowers) had a higher growth rate and developed faster, than those given senescent leaves alone, whereas the proportions of successfully emerged individuals did not differ. Lepidostoma probably benefits from the higher nitrogen content of the green leaves when used together with senescent leaves. 5. These results suggest that green leaves (or flowers) cannot serve as an alternative food resource to senescent leaves, but that they can enhance the growth and development of a Lepidostoma stream shredder if senescent leaves are also available.

    通し回遊型サクラマスの炭素・窒素安定同位体比を生活史ステージに沿って測定し、餌生物の安定同位体比との関係から濃縮係数およびターンオーバータイムを推定した。サクラマス卵の安定同位体比はその親魚と同等の高い値を示し、海洋での餌生物由来の物質を親魚から受け継いだことが示された。サクラマス幼魚の安定同位体比は、河川生活の開始直後においては卵と同様に高い値を示した。河川生活の進展に伴い幼魚の安定同位体比は河川での餌生物の値に近づくように低下したが、河川生活の開始およそ120日後以降変化が認められなくなった。この時点での安定同位体比は河川での餌生物の平均値と比べ、炭素で2.1‰、窒素で4.0‰高い値を示した。これらの値がサクラマス幼魚におけるそれぞれの元素の濃縮係数に相当し、ターンオーバータイムは120日程度であると考えられた。

    We investigated the amounts and types of organic matter that entered a coastal forest stream in Hokkaido, northern Japan. Organic matter input from the riparian forest was collected using litter traps, and benthic organic matter was collected from the streambed. Plant parts were weighed, and monthly nitrogen and carbon inputs were calculated. Organic matter input was highest in October, accounting for 58 % of the total annual amount, whereas input between May and August comprised only 22 % of the total amount. Frass and various plant parts, Such as flowers and green leaves, contributed nitrogen from May to August, and the total input during this period accounted for 39 % of the annual input, which was comparable to the input recorded in October. In May and June, senescent leaves accounted for 30-40 % to the total standing crop although only green leaves entered the stream during this period. To explore the relationship between benthic organic matter and stream macroinvertebrate density, we collected the two dominant summer growing shredder species (Goerodes complicatus [Trichoptera] and Sternomoera rhyaca [Gammaridea]). Densities of S. rhyaca were significantly related to the standing crop of detritus; G. complicatus showed the same trend, although the relationship was not significant. During spring and summer, plant matter that contained high levels of nitrogen contributed to increased nutrient resources in the stream. This organic matter probably affected the growth and development of stream macroinvertebrates when resources were scarce during early summer.
