The response of Ceratophyllum demersum and Myriophyllum spicatum to three levels of UV-B radiation – reduced (ca. 50% reduction), ambient and enhanced UV-B radiation, simulating 17% ozone depletion – is discussed. The research revealed
that UV-B stimulated the production of UV-B absorbing compounds in C. demersum, but not in M. spicatum. The relative amount of UV-B absorbing compounds was about four times lower in C. demersum. Enhanced UV-B also affected respiratory potential in C. demersum (on average 3.7 mg O2/gDM/h), but no effect on M. spicatum (on average 5.5 mg O2/gDM/h) was detected. Increased need for energy revealed that UV-B radiation exerted stress in C. demersum. No changes in chlorophyll a and no disturbance to photochemical efficiency due to UV-B were observed in either species. 相似文献

The objective of this investigation was to analyze the primary production of the dominant hydrophytes by monitoring levels
of organic matter and organic carbon and estimating photosynthetic potential via the total chlorophyll content. The survey
was conducted in Lake Provala (Serbia) throughout the peak vegetation period of the year 2000. The contents of organic matter
and organic carbon for Myriophyllum spicatum L. were 105.11 g m−2 and 73.66 g m−2, Nymphoides peltata (Gmel.) Kunt. were 95.51 g m−2 and 45.26 g m−2 and Ceratophyllum demersum L. were 52.17 g m−2 and 29.75 g m−2. Chlorophyll A (Chl a) and chlorophyll A+B (Chl a+b) pigments ranged from 1.54 mg g−1(Chl a) and 2.1 mg g−1(Chl a+b) in M. spicatum to 5.27 mg g−1(Chl a) and 7.53 mg g−1(Chl a+b) in C. demersum. At full leaf out, the latter aquatic plants exceeded 50% cover of the open water surface. All species achieved maximum growth
in June, but significant differences in growth dynamics were observed. At the end of the vegetation period, these plants sink
to the bottom and decompose 相似文献

The influence of macrophytes on a phytoplankton community in experimental conditions 总被引:23,自引:5,他引:18
Iwona Jasser 《Hydrobiologia》1995,306(1):21-32
The impact of submerged macrophytes or their extracts on planktonic algae was studied under experimental conditions. Live Ceratophyllum demersum L., its extract, and extracts of four other plant species induced modifications in the phytoplankton dominance structure. These modifications were: a decline in the number of Oscillatoria limnetica Lemm., which was the most numerous cyanobacterian species, and a decline in biomass and percentage contribution of all cyanobacteria to total algal biomass. This was accompanied by an increase in biomass and percentage contribution of green algae, especially Chlorella sp. and Chlamydomonas sp. Also, there was an increase in biomass and percentage contribution of nanoplankton (under 50 µm) to total phytoplankton biomass.The isolation of planktonic algae from direct influence of C. demersum by means of dialysis membranes caused an increase in number, biomass and percentage contribution of cyanobacteria. Release of organic compounds of over 3000 daltons by macrophytes apparently contributed to a decline of cyanobacteria by changing the phytoplankton dominance structure. 相似文献

The aim of this study was to estimate the influence of Ceratophyllum
demersum L. and Stratiotes aloides L. on the species richness and phytocoenotic diversity of aquatic vegetation in lakes. The study was based on field investigations
in the Łęczna-Włodawa Lake District located in mid-eastern Poland. The studied lakes (32) included both polymictic and dimictic
reservoirs. Both in the polymictic and dimictic lakes, statistically significant correlation coefficients were obtained between
the parameters that characterize Stratiotes aloides (the frequency in the phytosociological relevés, the percent share of Stratiotetum aloidis association in the phytolittoral) and those characteristic for species richness (the total number of hydromacrophytes, the
number of charophytes, elodeids, nymphaeids and lemnids), phytocoenotic richness (the mean number of species in the phytosociological
relevés) and phytocoenotic diversity (the Shannon–Wiener Index). The communities with a share of S. aloides are characterized by higher species richness. However, not a single case of statistically significant dependency was reported
between the parameters that describe C. demersum (the frequency in the phytosociological relevés, the percent share Ceratophylletum demersi association in the phytolittoral) and the vegetation traits in both lake groups. Common occurrence of Stratiotes aloides might be considered to be evidence for good status of an aquatic ecosystem and a very good indicator of species richness
and diversity of aquatic vegetation. 相似文献

Benthic macroinvertebrates associated with four species of macrophytes (Nymphoides peltata, Ceratophyllum demersum, Polygonum amphibium and Carex sp.) were investigated during two growing seasons (2001 and 2002) in the slow-flowing Čonakut Channel in the Kopački rit
Nature Park in Croatia. A total of 31 macroinvertebrate taxa were found. C. demersum, a submerged plant with dissected leaves, supported the highest macroinvertebrate abundance, almost seven times more than
N. peltata, a floating plant with undissected leaves, which harboured the lowest abundance during the research period. Chironomidae
larvae (50–83%) and Oligochaeta (14–46%) were the most abundant groups recorded on all macrophyte species. Water-level fluctuation,
because of its influence on the appearance and growth of aquatic vegetation, and the trophic state of water within the macrophyte
stands seemed to be the main factors which affected the taxonomic composition and abundance of macroinvertebrates. 相似文献

Abstract Plant scions of Ceratophyllum demersum L. and Potamogeton natans L. were exposed in controlled conditions to different concentrations of copper during approximately 2 weeks; Fv/Fm was monitored at regular intervals and relative growth rate (RGR) was calculated at the end of the trial. P. natans was affected by Cu concentrations starting from 2 μM; C. demersum started to show significant reductions in growth and photosynthetic efficiency from 4 μM Cu. As it results from the observed data, the two aquatic macrophytes can be used as valid bioindicators for medium-high copper concentrations in freshwaters. 相似文献

High macrophyte density in shallow lakes is often associated with clear water, especially when the non-rooted, submerged angiosperm Ceratophyllum demersum is dominant. Lack of true roots and high surface area:volume ratio suggest that nutrient uptake from the water column by C. demersum may be high. Therefore, possible competition for nutrients, including phosphorus (P), could contribute to phytoplankton inhibition.
C. demersum ability to absorb and store P at four nutrient levels (unenriched + three enrichment treatments) was investigated in a 34-day laboratory experiment using agar-based nutrient diffusing substrates (NDSs). P uptake rates and abatement potential by C. demersum were assessed from total phosphorus concentration (TP) patterns in the water column. Changes in C. demersum biomass (wet weight) also were determined. C. demersum took up P quickly. Some P release occurred during the experiment, especially under high nutrient conditions. Initial net P uptake by C. demersum was high, but medium-term (five weeks) average uptake was relatively low. Projected long-term net P uptake approached zero. Plant biomass loss and production of macrodetritus (plant fragments >1 mm) were highest in unenriched aquaria. Biomass loss in the lower enriched treatments was equally divided between loss as macrodetritus and as dissolved organic matter (DOM), but loss as DOM was four times higher than loss as macrodetritus in the highest nutrient treatment. The results suggest that medium- and long-term low phytoplankton biomass in C. demersum-rich lakes is achieved via mechanisms other than direct competition for nutrients from the water column. 相似文献

The phytoplankton species composition and seasonal succession were examined in Lake Kastoria during the period November 1998–October
1999. A total of 67 species and 19 functional groups were identified. Only 4 out of the 67 species, all Cyanobacteria, were
dominant (Limnothrix redekei, Microcystis aeruginosa, Cylindrospermopsis raciborskii and Aphanizomenon gracile). Diatoms were rare, not only in terms of species number, but also in terms of biomass (contributing <5% to the total phytoplankton
biomass) in relation to the rather low silicon concentrations throughout the year. The functional groups S1, SN, M and H1 were found dominant in the lake. The species A. gracile (functional group H1) behaved like the species Cylindrospermopsis raciborskii (functional group SN) which is tolerant to mixing and poor light conditions. The phytoplankton seasonal succession showed similar patterns in
all six sampling stations, both at the surface and the bottom water layer, with minor differences during Microcystis aeruginosa dominance. Two steady-state phases were identified within a year lasting for 4 months under relatively stable physical conditions.
In these steady-states, the Limnothrix redekei persistent dominance under low light availability and low inorganic nitrogen has been explained by its specific ability such
as buoyancy regulation to exploit resources in the water column. Moreover, high population densities over the winter and before
the development of daphnids may contribute to the steady-state dominance of Limnothrix. Different niches separated vertically in the water column is one of the explanations for the Limnothrix–Microcystis steady-state when a replacement between the two species was observed in different water layers and areas of the lake. Long
lasting steady-states of Cyanobacteria observed in Lake Kastoria and in other Mediterranean and tropical freshwaters may indicate
influence of warm climate properties on phytoplankton dynamics.

The abundance and distribution of predatory cladoceran Leptodora kindtii was investigated in the estuarine lagoon (Curonian Lagoon, SE Baltic Sea). Three hydrodynamically different parts of the
lagoon were selected, representing transitory oligohaline, intermediate freshwater and stagnant freshwater sites. L. kindtii was least abundant at the oligohaline site, never occurring at salinities greater than 4 psu. At the two freshwater sites,
the abundance of L. kindtii varied from a low of <0.1 up to 2.2 indv. L−1 during peak abundance. Two peaks of L. kindtii abundance were observed with timing differences between stations: at the stagnant site the population of L. kindtii peaked two weeks earlier relative to the more hydrodynamically active sites, likely due to a 2°C higher May temperature.
The small body size of L. kindtii in the lagoon (seasonal mean 2.68±0.6 mm) shows high fish predation pressure and predicts small cladocerans, juvenile copepods
and rotifers being in the preferred prey size range. The calculated L. kindtii daily consumption during the population peak was as high as 100% of the daily zooplankton production, which implies high
potential of this predator to shape the grazing zooplankton community in the lagoon. 相似文献

Lake Ellesmere (Te Waihora) is a nationally important coastal brackish lake in New Zealand, however degradation in water quality
and loss of submerged macrophytes over past decades have raised concerns in regards to the declining status of the lake’s
commercial and customary fisheries, predominantly targeted at shortfin eels (Anguilla australis). We investigated foodweb dynamics and trophic linkages to shortfin eels in Lake Ellesmere using a combination of abundance
assessments, dietary studies, and stable isotope analyses. Data from our study are compared with historical data sets on benthic
invertebrate community composition and shortfin eel diets to trace changes in the trophic linkages to top predators that have
occurred since the late 1960s. Stable isotope analyses indicate that the foodweb is predominantly driven by epipelic and phytoplankton
derived carbon sources, although it was difficult to discriminate between these two carbon pools because of wind-driven resuspension
of lake sediments. Comparison of our survey results with historical data sets indicates a clear shift in benthic biota from
being dominated by phytofaunal species such as Potamopyrgus antipodarum (comprising 90% of total invertebrate biomass) during the 1960s, to now being almost entirely comprised of subterranean species
such as Chironomus zealandicus and oligochaetes (together comprising 82% of total invertebrate biomass). This shift in benthic communities has resulted
in significant changes in the size-specific diet of juvenile shortfin eels (<400 mm) from those reported for Lake Ellesmere
during the mid 1970s, with Chironomus larvae now comprising 65% of the diets of juvenile eels, whereas historically P. antipodarum was the dominant food item (>30% of total biomass). This shift towards foraging on smaller sediment-dwelling species could
have implications for juvenile eel bioenergetics, and may help explain why juvenile shortfin growth rates have significantly
decreased in past decades. Juvenile shortfins now appear to switch to foraging on preyfish (mainly common bullies, Gobiomorphus cotidianus) at a smaller size (≈400 mm) than historically recorded (>500 mm). Dietary and stable isotope signatures indicated that small
shortfins (100–299 mm) have considerable overlap in trophic position (δ13C = −20.4‰, δ15N = 13.6‰) with common bullies (δ13C = −20.5‰, δ15N = 13.7‰), the dominant fish in Lake Ellesmere (92% of total abundance CPUE), potentially indicating that these two species
may directly compete for food resources. These findings again highlighted the importance of C. zealandicus in sustaining the fish populations of the lake.

Macroinvertebrate composition, abundance and biomass were investigated at four intertidal sites throughout the Robbins Passage
wetlands, Tasmania, over a 12-month period, in order to identify differences among and within sites, and to determine whether
environmental variables could explain these differences. As this region is the most important shorebird area in Tasmania,
we wanted to quantify the potential food source for shorebirds within the wetlands. Thirty-five taxa from 28,928 individuals
were identified, with a mean abundance of 6026.6 ind m−2 and biomass of 27.1 gDW m−2. Bivalves and gastropods dominated the assemblage in terms of abundance and biomass (79% and 60%, respectively). There was
a significant interaction among tidal level, site and season for invertebrate abundance and diversity, while biomass differed
significantly among sites. In general, the mid-intertidal stratum had the greatest invertebrate density and diversity, while
the low intertidal stratum had the greatest biomass. Community composition varied among the four sites, with the bivalve Paphies
elongata dominating at two of the sites, while gastropods and polychaetes were more abundant at the other sites. Differences in invertebrate
composition and abundance could partly be explained by seagrass biomass, i.e., dry mass of seagrass leaves and roots. Areas
with seagrass had increased invertebrate abundance and diversity, but mean sediment particle size, % organic carbon and %
seagrass cover had no significant effect. These results will assist in the investigation of habitat use by shorebirds and
the identification of important shorebird feeding areas within the wetlands.

为研究湿地沉水植物腐败分解对水体的污染状况,选择典型沉水植物金鱼藻(暖季植物)和菹草(冷季植物)进行了为期60 d的凋落物分解实验。结果表明金鱼藻和菹草凋落物分解规律相似,0—15 d快速分解,15—60 d缓慢分解,60 d凋落物失重率分别达到60.43%和66.72%。菹草的有机物释放量明显高于金鱼藻,N和P释放量相反,分解释放的N主要是NH4+-N和有机氮。三维荧光光谱(Excitation-Emission Matrix Spectroscopy, EEMs)结合平行因子分析法解析出一种类色氨酸物质C2和3种类腐殖质物质C1、C3、C4,易降解的类色氨酸有机物先增加后减少,难降解的类富里酸和类腐殖酸有机物逐渐增加。EEMs和四种组分的最大荧光强度百分比表明,溶解性有机物(Dissolved organic matter, DOM)在0—15 d以易降解有机物为主,15—60 d以难降解有机物为主。两种植物凋落物分解释放的DOM含量及特性不同,整体上呈低腐殖化特征,可能是水中难降解DOM的一个重要来源。植物凋落物的分解促进了沉积物中微生物的丰富度,降低了微生物的多样性;参与分解的主要微生物包括4 d时的Pseudomonas属(26%—35%)、15 d和30 d时的Malikia属(>8%)和Bacillus属(2.6%—9%),分解难降解有机物的微生物逐渐增加,如Flavobacterium属;沉积物中微生物群落结构的变化受营养物质可利用性变化的影响。分析发现植物凋落物分解对水质的影响具有阶段性,0—15 d,N和P释放量增加暂时导致了水质恶化;15—60 d,N和P释放量降低,难降解有机物含量逐渐增加,可能会加剧水体甚至是沉积物的腐殖化程度。因此,在植物衰亡期应及时打捞或者做好植物平衡收割管理,避免因植物大量腐败导致水质恶化。 相似文献

Spatial heterogeneity is common in aquatic conditions, but few studies have examined the effects of heterogeneous distributions of biological factors on aquatic plants. Spirogyra (Spirogyra arcta) coexists with many submerged macrophytes, such as Ceratophyllum demersum, but no study has examined the effects of heterogeneous distributions of spirogyra on the growth of submerged plants. We grew the submerged plant C. demersum in three homogeneous, aquatic conditions (0, 50 and 100% of the water surface in the container was evenly covered by spirogyra, referred to as ‘control’, ‘50%’ and ‘100%’, respectively) and two patchy conditions (the left half of the water surface in the container was not covered by spirogyra and 50% and 100% of the water surface in the right half of the container was evenly covered by spirogyra, referred to as ‘50%‐patchy’ and ‘100%‐patchy’, respectively). Compared with the control, the 100% treatment greatly decreased the biomass and number of ramets of C. demersum, but the 50% treatment did not. Growth of C. demersum in the left half of the container did not differ significantly between the control and the two heterogeneous treatments (50%‐patchy and 100%‐patchy). In addition, growth of C. demersum in the right half of the container did not differ between the 100% and the 100%‐patchy treatment or between the 50% and the 50%‐patchy treatment. Our results suggest that C. demersum can tolerate shading by spirogyra to a certain extent and that heterogeneous distributions of spirogyra do not affect its growth. 相似文献

The presence of algae can greatly reduce the amount of light that reaches submerged macrophytes, but few experimental studies have been conducted to examine the effects of algae on biomass and structure of submerged macrophyte communities. We constructed communities with four submerged macrophytes (Hydrilla verticillata, Egeria densa, Ceratophyllum demersum, and Chara vulgaris) in three environments in which 0 (control), 50 and 100% of the water surface was covered by Spirogyra arcta. Compared to the control treatment, the 100% spirogyra treatment decreased biomass of the submerged macrophyte communities and of all the four macrophytes except C. demersum. Compared to the control and 50% treatments, the 100% treatment significantly increased relative abundance of C. demersum and decreased that of E. densa. Therefore, the presence of S. arcta can greatly affect the productivity and alter the structure of submerged macrophyte communities. To restore submerged macrophyte communities in conditions with abundant algae, assembling communities consisting of C. demersum or similar species may be a good practice. 相似文献

Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae) is a parasitic wasp which plays an important role in the biological control
of a number of aphid species. Through assessment of its thermal biology and low temperature tolerance, this study ascertains
the establishment potential of L. testaceipes in cool temperate climates typical of northern Europe. The developmental threshold of L. testaceipes was 5.8°C. Rearing of parasitoids at shorter day lengths and lower temperatures indicated no ability to enter a diapause
state. The supercooling points (SCP) of non-acclimated and acclimated parasitoid life stages were between −24.6°C and −17.7°C,
with LTemp50 temperatures approaching these values, indicating a high level of cold tolerance in short exposures. At 5°C the LTime50 of acclimated larvae within parasitized aphids was 42.8 days. Acclimated pupae continued to develop with 54% adult emergence
from mummies within 60 days. Acclimated parasitoid larvae and pupae, within living and mummified aphids, continued to develop
during 70 days of winter field exposure and emerging adult parasitoids were reproductively viable under field conditions.
These data indicate that where suitable host species are available throughout the year, L. testaceipes would be able to establish in northern Europe. 相似文献

We examined the uptake of five heavy metals (Cu, Fe, Ni, Zn, and Mn) in Ceratophyllum demersum L. (hornwort) and Potamogeton alpinus Balb. (pondweed) from Iset’ river, Ural region, Russia. This study was conducted in a territory that is highly urbanized where the surface waters are contaminated by a wide spectrum of pollutants. The environmental situation in this territory drastically deteriorated due to anthropogenic activity. The water quality in most of the water bodies in the Ural region is rather poor. In a comparative study ofC. demersum and P. alpinus, differential accumulation pattern was noted for heavy metals (HMs). Higher amounts of HMs accumulated in C. demersum compared to P. alpinus. Also it was shown that in leaves of C. demersum there were high amount of total phosphorus, nitrogen, organics acids and ash; high activity of guaiacol peroxidase; high content of non-enzymatic antioxidants viz., flavonoids, ascorbate, glutathione and proline; high amount of thiols (soluble and membrane bound) compared to P. alpinus. 相似文献

The shipworm Teredo navalis L. is a xylophagous bivalve mollusc (Bivalvia: Teredinidae) with a long record of being very destructive to wooden ships
and harbour buildings. It has been reported from numerous sites at the coasts of both the North and Baltic Seas since the
eighteenth century. Here, we document for the first time the occurrence of live adult T. navalis in the harbours of Bremerhaven (Weser estuary, northern Germany). From August to December 1998, various wooden structures
(fir floating fenders and pier posts, oak piles) from seven stations in different docks of two harbours (überseehafen, Fischereihafen)
were investigated for the presence and density of live specimens and burrows of T. navalis. The settlement of larval shipworms was studied by exposing experimental fir panels 0.06 m2 in size at 20 stations at water depths between 1 and 2 m for periods of 4 months between July and November. In addition,
hydrographic profiles (0–8 m water depth) were obtained at 17 stations in five docks once every month from August to December.
Live adult shipworms were found in both fir floating fenders and oak piles at four stations. The largest specimen found was
250 mm long. Shipworm burrows were detected at five stations in almost every wooden structure investigated but their abundances
differed significantly: Maximum values were >10,000 m–2 in fir floating fenders, 4,600 m–2 in oak piles and 200 m–2 in fir pier posts. Actual shipworm infestation was detected at three of 16 stations in the exposed fir panels (1–3 burrow
holes per panel). Water temperatures and salinities varied considerably during the 4-month investigation period. Temperatures
decreased from 19.9°C in August to 0.7°C in December. Salinities ranged from 17.6 in August to 1.1 in November, but only at
two lock stations during November and December did value drop below 5, which is regarded as the lethal limit for the larvae
of this euryhaline teredinid species. We conclude that T. navalis encounters favourable conditions for growth and reproduction in the harbours of Bremerhaven, at least during summer and autumn,
and is a common element of the harbour ecosystem. Therefore, a persistent infestation of all wooden structures after a relatively
short period of time seems to be highly probable.

Conventional and biological control of a native moth, Dalaca pallens (Blanchard) (Lepidoptera: Hepialidae), were evaluated in Southern Chile in relation to changes on community metrics (diversity,
species richness, evenness and dominance) of a soil-dwelling invertebrate assemblage. Two experiments were conducted (in winter
and spring) to compare non-target effects of Beauveria bassiana (Balsamo) Vuillemin and lambda-cyhalothrin insecticide. The invertebrate community was sampled before and after spraying
by extracting soil cores. Estimates of diversity (Shannon index), species richness, evenness (Hurlbert’s Probability of Interspecific
Encounter) and dominance indicated that the invertebrate assemblage was strongly disturbed by lambda-cyhalothrin treatment
but not by B. bassiana applied in winter, over the sampling period (40 days). Spring results revealed that diversity and evenness at control and
at B. bassiana plots were similar between them and higher than at lambda-cyhalothrin plots, while there were no differences between sites
30 days after treatment in species richness. Inundative biological control using B. bassiana strain QU-B931 was considered to pose lower ecological risk than lambda-cyhalothrin, currently one of the most frequently
used insecticides for D. pallens control. 相似文献

The effect of acetic acid and formic acid on acetone-butanol-ethanol (ABE) production by solventogenic Clostridia was investigated.
The ABE concentration in Clostridium acetobutylicum was found to have increased slightly on addition of 3.7 ∼ 9.7 g/L acetic acid, but was found to have drastically reduced
in the presence of 11.7 g/L acetic acid. However, the solvent production of C. beijerinckii was not affected by addition of acetic acid in the range of 3.7 ∼ 11.7 g/L. C. acetobutylicum was more vulnerable to formic acid than C. beijerinckii. In C. acetobutylicum, the total ABE production decreased to 77% on addition of 0.4 g/L formic acid and 25% with 1.0 g/L formic acid. The total
ABE production by C. acetobutylicum was also noted to have decreased from 15.1 to 8.6 g/L when 8.7 g/L acetic acid and 0.4 g/L formic acid co-existed. The solvent
production by C. beijerinckii was not affected at all under the tested concentration range of formic acid (0.0 ∼ 1.0 g/L) and co-presence of acetic acid
and formic acid. Therefore, C. beijerinckii is more favorable than C. acetobutylicum when the ABE is produced using lignocellulosic hydrolysate containing acetic and formic acid. 相似文献
