Macrozoobenthos is one of the organisms that can be used as biological indicators because it tends to live in an area and has sensitivity to environmental changes. The Hurun River had many community activities. Based on this, it was necessary to analyze the diversity of macrozoobenthos which will be compared with the physical and chemical parameters of water in order to find out the indicators that affect the abundance of macrozoobenthos in the river. The purpose of this research was to determine the macrozoobenthic community structure which found in the Hurun River based on diversity, uniformity and dominance indices, to build multiple linear regression models, and to determine the bioindicators of pollution in the Hurun River. The factors that influence the abundance of macrozoobenthos are temperature, depth, brightness, DO, TOM, and salinity. The types of macrozoobenthos obtained were 87 species with the highest abundance of macrozoobenthic animals of 70,666.56 ind/m3 while the lowest abundance of macrozoobenthic animals was 13,000.96 ind/m3. Based on data analysis, the macrozoobenthic diversity index was included in the medium category, the level of macrozoobenthic uniformity was included in the high, medium, and low categories, and the dominance level which was included in the medium and low categories. Multiple regression models with a confidence level of 5% get R2 results of 0.86. The level of pollution that occured in the Hurun River based on bioindicators with the ABC curve shows moderately polluted.

This study aims to determine the macrozoobenthic community, the effect of rock mining on the macrozoobenthic community, and the water quality of the Logawa River. The research method used is purposive random sampling technique at 5 stations with 3 replications. The results showed that species richness, individual abundance and diversity were low at several stations because not all macrozoobenthos had a tolerance value for living in waters where sediment conditions had been affected by rock mining. Meanwhile, the dominance index value of the high category at station 3 was due to the effects of rock mining which caused macrozoobenthos who were intolerant of rock mining to move, so that only macrozoobenthos that were resistant to such conditions survived and dominated the area. Water quality for macrozoobenthos is still quite good based on the measurement results.

Mangrove ecosystems are unique ecosystems found along the coast or river mouths that are still influenced by tides. Association is a process of interaction between organisms and their environment which is not simple but a complex process. One of the biota associated with mangroves is macrozoobenthos. This research was conducted in August 2021. The purpose of the study was to determine environmental conditions, mangrove species and density, macrozoobenthic species and density, and the relationship between macrozoobenthic density and mangrove forest density in Dumai waters. Based on the results of the study, the types of macrozoobenthos were found from the gastropod and bivalves classes. The type that is found in all stations is Nerita lineata. The highest density is at station III, which is 19.11 ind/m2. Mangroves in Dumai waters are classified as dense with the dominant species being Rhizophora apiculata and Xylocarpus granatum. The relationship between the density of macrozoobenthos and the density of mangroves belongs to the medium category

Abstract Distribution patterns and species composition of macrozoobenthos were studied in the Dutch coastal zone in front of the Port of Rotterdam. Relationships between macrozoobenthic assemblages and environmental variables were determined using non-metric dimensional scaling (nMDS) based on 470 boxcore, bottom sledge, and sediment samples collected in spring 2006 and 2008 in a 2500-km2 research area. We investigated two types of benthic assemblages, infaunal assemblages sampled with a boxcorer and epifaunal assemblages sampled with a bottom sledge. Five main in- and epifaunal assemblages were distinguished using clustering techniques and nMDS ordinations. Macrozoobenthic species composition correlated with combinations of measured sediment variables and modelled hydrodynamic variables. Macrozoobenthic species richness and biomass were highest at 20 m deep areas with a grain size of 200 µm, elevated mud and sediment organic matter, and low mean bed shear stress. Considerable interannual differences in macrozoobenthic assemblage distribution were observed which resulted from more Echinoids, Phoronids, and jackknife clams. A distinct, highly productive and species-rich macrozoobenthic white furrow shell Abra alba assemblage coincided in a 8-m deepened shipping lane and near a disposal site for dredged fine sediment. This may be an indication that the benthic system can be changed by these human activities. Modelled bed shear stress is an important variable in addition to sediment variables in explaining distribution patterns in macrozoobenthos.

The macrozoobenthic structure inhabiting marine ecosystem may be used as a bioindicator of changes in aquatic environmental disturbance. This study is aimed to assess environmental disturbance by application of biomonitoring using macrozoobenthic assemblages at coastal area of Menjangan Besar Island, Kepulauan Karimunjawa, Indonesia. The macrozoobenthic assemblages were assessed at two sampling locations, i.e. floating net cage of monoculture and reference areas. Each sampling location consisted of three stations with three replicates for each station. The samples were taken in two sampling times, i.e. August and November 2018. Data of abiotic parameters included the composition of organic matter content, sediment substrates, DO, pH, salinity, temperature, and water current. Sediments were sampled using Ekman grab from 15 m deep. The relationship between biotics (macrozoobenthos) and abiotics (physical-chemical factors) was assessed using a non-parametric multivariate procedure (BIO-ENV; Primer 6.1.5). Macrobenthic assemblages consisted of 89 species with the total abundance of 50,071 individuals/m2, consisting of 52 families and 4 classes of macrozoobenthos. The values of indices were ranging from 2,54-3,40 for diversity index (H'), 0,99 for Pielou’s evenness index (e’), and 0,09-0,17 for dominance index (C). The most common classes were a member of Gastropods and bivalves. Diversity and evennes indices exhibited differed by location (monoculture vs reference) and time sampling. Fluctuation of macrobenthic structure was considered as a results of environmental changes spatially and temporally, especially sediment composition and food availability as the form of organic matter. Nitrogen and silt were the most chemical and physical factors influencing the structure of macrozoobenthos (r = 0,632; BIO-ENV).

The aim of this thesis has been to: 1) assess the state of pollution in the two study areas and relate them to recent changes found in the Kattegat - Belt Sea area; 2) examine the observed spatial and temporal variability in species composition, abundance and biomass in Arhus Bay and the Formes area and relate the variability to antropogenic and natural causes; 3) discuss and assess methods, particularly for the estimation of secondary production and the use of multivariate analyses as methods for examining changes in macrozoobenthic communities. Macrozoobenthos were sampled at 15 stations in Arhus Bay, Denmark from 1985 to 1991 while data from Formes (reference area) included 55 sampling stations from 1986 to 1990. Monthly sampling took place at one station in Arhus Bay in 1990 and 1991. The two study areas are both situated on the eastcoast of Jutland in the Kattegat - Belt Sea area at 13-17 m depth and both receive waste water from long sea outfalls. Although both areas are Subjected to salinity stratification for most of the year, the exposed position of the Formes area on the open Kattegat coast prevents it from suffering from severe oxygen deficiencies, unlike the Arhus Bay which is a sheltered, semi-enclosed sedimentation area where oxygen concentrations in the bottom water can be very low. At Formes the sediment is sandy while it is silty in Arhus Bay. The spatial and temporal variability in the benthos in Arhus Bay could to a great extent be explained by the variation in 7 important species: Abra alba, Corbula gibba, Mysella bidentata, Nepthys hombergii, N. ciliata, Ophiura albida and Echinocardium cordatum. The fluctuations in the number and biomass of A. alba had a pronounced effect on the total abundance and biomass in Arhus Bay. The severe winter of 1986/87 with low temperatures and oxygen depletion under the ice cover practically eliminated A. alba from the bay. A. alba quickly recolonized the area and was found in high numbers in 1988. Studies of growth of A. alba in 1990 and 1991 showed that by the end of 1990 the population had reached an average length of 10 mm while the average shell length was only 5 mm by the end of 1991. The difference between the two years could be attributed to the difference in sedimentation of phytoplankton from the water column. As in other parts of the Kattegat - Belt Sea area, Arhus Bay has experienced low oxygen concentrations in the bottom water in late summer early autumn throughout the 1980s. Only the oxygen depletion under the ice cover in early spring 1987 and the local oxygen deficiencies south of the outlet in 1989 and 1990 actually killed parts of the benthic fauna. Apart from 1981, the oxygen deficiencies have thus been less severe in Arhus Bay than in other parts of the southern Kattegat in the 1980s. The number of species, abundance and biomass decreased at Fornres from 1980 to 1985 while the discharge of BOD was fairly constant during the same period. From 1986 there was a slight decrease in the discharge of BOD but a considerable increase in the number of species, abundance and biomass. At least for the second half of the 1980s there was no straightforward relation between the organic enrichment from the outlet and species composition, abundance and biomass and suggests that other factors are also important influencing the fluctuations in the benthic fauna. Estimates of total secondary community production were found to be very dependent on the method used. The method described by Brey (1990) was found acceptable for estimating secondary production in Arhus Bay but care should be exercised when comparisons are made with other areas where different methods have been used to estimate production. Secondary production was estimated more accurately for some of the abundant species in Arhus Bay on the basis of monthly samplings by the method described by Crisp (1984). Among the multivariate analyses the Detrended Correspondence Analysis (DCA) and nonmetric Multidimensional Scaling (MDS) proved to be the most successful with the Arhus Bay and Fornes data sets. Two Way INdicator SPecies ANalysis (TWINSPAN) did not work well with the Fornes data because it imposed discontinuities on data sets with continous variation in distribution of species among samples. As community types existed to a certain degree in Arhus Bay TWINSPAN worked well with these data. DCA and MDS were found to be useful techniques for analysing large data sets because they can summarize the data matrices to a manageable form and find possible patterns in the data sets. The results of the analyses can then be used as starting point for more detailed investigations of single species/samples or groups of species/samples. By using different transformations of the raw data the role of dominant or rare species can be assessed. A major 'problem in the assessment of multivariate techniques is the lack of external standards to compare with. The results of multivariate analyses must therefore be assessed critically on the basis of a careful examination of the species list combined with the knowledge and experience of the investigator. The methods used all had their advantages and limitations but each of the different methods added some important information to the picture of the benthic community in Arhus Bay and Fornes. It was thus an considerable advantage to use several different methods to analyse the spatial and temporal variability in the benthic fauna in relation to antropogenic and natural causes.

Ziel dieser Dissertation ist, Wissensdefizite im Bereich der Bioirrigation von Süßwassersedimenten abzubauen. Als Untersuchungsorganismus wurde Chironomus plumosus ausgewählt weil diese weit verbreitete Larve ihre U-förmigen Röhren mit Überstandswasser durchspült und so Nahrung aus dem Wasser filtriert. Um Bioirrigation in Wohnröhren mit einem Durchmesser von ca. 1,7 mm zu untersuchen, wurden geeignete Messmethoden entwickelt, mit denen für das 4. Larvenstadium die Parameter Fließgeschwindigkeit (14,9 mm/s), Pumpzeit (33 min/h) und Pumprate (61 ml/h) gemessen wurden. Bei einer Populationsdichte von 745 Larven/m2 kann somit ein Wasservolumen äquivalent zum Volumen des Müggelsee in Berlin, innerhalb von 5 Tagen durch das Sediment gepumpt werden. Die Positronen-Emissions-Tomographie wurde für die Sedimentanalytik adaptiert und der Transport im Porenwasser analysiert. Mit den Untersuchungen wure gezeigt, dass auch in schlammigen Seesedimenten ein advektiver Transport durch Bioirrigation verursacht wird, der nicht zu vernachlässigen ist. Steigende Temperaturen resultieren aufgrund steigender Fließgeschwindigkeit in einen signifikanten Anstieg der Pumprate sowie der Eintragsrate von Überstandswasser ins Sediment. Ein abfallender Sauerstoffgehalt verlängert die Pumpzeit und führt zu einer sinkenden Fließgeschwindigkeit. Außerdem wird aus den Untersuchungen eine jahreszeitliche Variabilität der Bioirrigation sichtbar, welche unabhängig von konstanten Laborbedingungen auftritt. Mit dem Wasserstrom werden Porenwasserspezies wie SRP in den Wasserkörper abtransportiert, wohingegen SO42- und O2 aus dem Überstandswasser in das Sediment eingetragen werden. Ferner kommt es zur Oxidation von Fe2+ infolgedessen Phosphat im Sediment festgelegt wird, wie mittels P-Fraktionierung gezeigt werden konnte. Mikrobiologische Untersuchungen zeigten, dass Bioirrigation die mikrobielle Abundanz steigert, die Bakteriengemeinschaft verändert und das Potential zur enzymatischen Hydrolyse erhöht.
The aim of this thesis is to fill gaps of knowledge regarding bioirrigation in freshwater sediments. Chironomus plumosus was chosen for the investigations since the filter-feeding larva dwelling in U-shaped burrows is quite common and flushes its burrow with water from the overlying water body. To investigate bioirrigation activity in burrows of approximately 1.7 mm in diameter appropriate measurement techniques were developed. With the methods several parameters were measured for 4th stage of larvae: flow velocity (14.9 mm s-1), pumping time (33 min h-1), and pumping rate (61 ml h-1). Consequently, a water volume equivalent to the volume of Lake Müggelsee in Berlin is pumped through the sediment every 5 days by a population density of 745 larvae m-2. The nuclear medicine imaging technique Positron Emissions Tomography was adapted and used to analyze the transport in the sediment pore water. By means of the experiments, it could be shown that even in muddy lake sediments advection is a relevant transport process and should not be neglected. Rising temperatures result in increased pumping rates and increased influx rates of surface water into the sediment due to increased flow velocities in the burrows. Dropping oxygen concentrations prolong the pumping duration while the flow velocity decreases. Furthermore, experiments show a seasonal variability of bioirrigation which is independent of constant laboratory conditions. Pore water species such as SRP are transported with the water flow into the overlying water body, whereas SO42- and O2 are transported from the overlying water into the sediment. Due to the oxidation of Fe2+, phosphorus is fixed into the sediment, a result confirmed by P-fractionation. Microbiological investigations of the burrow walls demonstrated that the bioirrigation activity enhances the microbial abundance, changes the community structure, and increases the potential of enzymatic hydrolysis.

The objectives of this study were to characterise macrozoobenthic community structure of the western sector of Algoa Bay, to identify the drivers of community structure and to develop a long-term monitoring framework. Data were collected from six study sites stratified along-shore. Each site comprised three stations; most sites were located in areas directly influenced by anthropogenic activities such as inflow from storm water drains and areas where dredged spoil was dumped. Other sites included areas in close proximity to estuary mouths. Physico-chemical parameters of the water column were measured with a YSI instrument, sediment for faunal and physico-chemical analyses was sampled with a Van Veen grab, and collected macrofauna were sedated and preserved pending analysis. In the laboratory, macrofauna were identified to finest taxonomic resolution possible under dissecting and compound microscopes, and enumerated. Sediment samples for physico-chemical analyses were kept frozen pending analysis. Up to 187 species belonging to 137 genera and 105 families were identified. Univariate community parameters such as abundance and number of species varied significantly along-shore, generally increasing towards less wave-exposed sites. Multivariate analyses revealed that community assemblages were heterogeneously distributed along-shore, corresponding to areas where anthropogenic influences such as effluent discharge and commercial harbour activities prevailed. During the 2008 survey, species assemblages separated into six groups corresponding to the six sites but xvii during the 2009 survey, species assemblages separated into four groups probably due to changes in environmental parameters such as the hydrodynamic regime. In both surveys the assemblage opposite a drainage canal (Papenkuils outfall) was distinct as it was dissimilar to all other assemblages. This site was also heterogeneous over relatively small spatial scales. Important physico-chemical variables influencing community structures during the 2008 survey included bottom measurements of temperature, salinity, dissolved oxygen, coarse sand and mud. During the 2009 survey, only bottom temperature and mud content were identified as important physico-chemical variables structuring community assemblages. The principal variable was probably the hydrodynamic regime, driving community structure at a larger scale in Algoa Bay. On a localised scale, communities were probably structured by other factors such as effluent discharges, influence of estuary mouths and activities associated with the harbour. With a lack of information on keystone species (regarded as good monitoring species) in Algoa Bay, it was proposed that groups that cumulatively comprise 50–75 percent of total abundance within communities be monitored annually. Included are amphipods, polychaetes, cumaceans, ostracods, tanaids and bivalves. It was also proposed that areas opposite estuary mouths, effluent outfalls and the dredged spoil dumpsite be monitored. This routine monitoring programme should be accompanied by periodic hypothesis driven research to assess the importance of stochastic events (e.g., upwelling) on macrozoobenthic community dynamics. Keywords: macrozoobenthos, soft-bottom, community assemblages, spatial distribution patterns, environmental drivers, long-term monitoring framework.

A rápida expansão da carcinicultura em áreas costeiras tem sido associada a vários distúrbios ambientais. A principal preocupação reside na descarga de efluentes ricos em nutrientes e matéria orgânica para os estuários e seu impacto sobre a biota. Considerando a macrofauna bentônica como indicador de estresse ambiental, o presente trabalho teve como objetivo determinar o impacto do aporte de efluentes da carcinicultura no estuário do rio Botafogo (Itapissuma-PE). Foram estabelecidas 3 estações: a montante, próximo ao ponto de despejo de efluentes e a jusante, além de 3 estações-controle no rio Siri (Goiana-PE). O macrobentos foi coletado em fevereiro e junho/2003, no mediolitoral e infralitoral. Foram amostrados parâmetros indicadores de estado trófico da água e dos sedimentos, além de descritores físico-químicos e sedimentológicos. A macrofauna foi identificada e quantificada quanto à abundância, biomassa e produção relativa. A estrutura da comunidade foi estudada através de medidas univariadas (Diversidade, Equitatividade, Abundância, Riqueza), distribucionais (Curvas ABC e Distribuição dos Táxons pelas Abundâncias), multivariadas (Ordenação MDS/ANOSIM/BIOENV, Meta-Análise, Dispersão Relativa) e multimétricas (Índice Bêntico). Não foram identificadas diferenças importantes (p>0,05) entre os estuários quanto aos indicadores de impacto orgânico (clorofila-a, Ntotal, P-total, percentuais de matéria orgânica e silte-argila nos sedimentos). Entre os índices univariados, somente as elevadas riqueza e abundância do rio Botafogo o diferenciaram (p<0,05) das estações-controle. As Curvas ABC, a Distribuição dos Táxons pelas Abundâncias, o Índice Bêntico e a Meta-Análise detectaram perturbações em ambos os estuários, diferindo, entretanto quanto à intensidade ou à distribuição espaço-temporal dos diagnósticos. O MDS/ANOSIM mostrou diferenças significativas (p<0,05) entre rios. O BIOENV discriminou a matéria orgânica, pigmentos fotossintéticos e o P-total nos sedimentos, e a temperatura e a amônia na água, como os fatores que melhor explicaram as associações bióticas do rio Botafogo. No rio Siri as variáveis associadas foram a clorofila-a do sedimento e o Eh da água. O rio Siri foi invalidado como ambiente controle por apresentar evidências de distúrbios, porém de origem incerta. Apesar de não ter sido constatada simplificação na estrutura da comunidade, o rio Botafogo apresentou alterações estruturais no macrobentos características da fase inicial de enriquecimento orgânico, provavelmente, em resposta ao aporte de efluentes da carcinicultura

The thesis focuses on the macrozoobenthic community in the Lagoon of Venice. Main aspects investigated include: spatial and interannual variability of the community structure; the role of environmental factors in structuring benthic communities; spatial scales of variability of the community, also in relationship to variability scales of environmental factors. A three-year data set was analyzed. High interannual variability and spatial heterogeneity was verified. Multivariate structure and univariate descriptors were considerably related to environmental factors. A gradient from sea landwards in species richness and community composition was evidenced and related to the composite ecocline, mainly to seawater renewal and salinity. More complex spatial patterns were recognized. Univariate descriptors and multivariate structures follow different scales of variability. The results have implications for quality assessment of transitional ecosystems.
La tesi analizza la comunità macrozoobentonica della Laguna di Venezia. Sono stati principalmente indagati: la variabilità spaziale e interannuale della struttura della comunità; il ruolo dei fattori ambientali; le scale spaziali di variabilità della comunità, in relazione alla scala di variabilità dei fattori ambientali. Il data set analizzato è relativo a tre anni. E' stata verificata un'elevata variabilità interannuale ed eterogeneità spaziale. Descrittori di struttura multivariata e univariate sono risultati notevolmente correlati ai fattori ambientali. E' stato evidenziato un gradiente da mare verso terra in merito al numero di specie e alla composizione della comunità, in relazione ad un ecocline composito, e principalmente a ricambio idrico e salinità. Sono emersi pattern spaziali più complessi. Descrittori univariati e strutture multivariate seguono diverse scale di variabilità. I risultati hanno implicazioni per la valutazione della qualità degli ecosistemi di transizione.

Le spiagge sabbiose sono uno dei luoghi più importanti, non solo in quanto sostengono la biodiversità fornendo habitat e cibo, ma anche aiutando il sostentamento umano fornendo opportunità socioeconomiche. La crescente pressione sulle spiagge sabbiose sta portando al degrado dell'ecosistema costiero. Per comprendere queste minacce e il loro impatto sulle comunità macrobentoniche intertidali, è stato svolto questo progetto. Inizialmente, i dati relativi a determinati impatti umani sono stati raccolti a livello globale sotto forma di una revisione sistematica per evidenziare le lacune. I dati relativi agli impatti delle perturbazioni antropiche sul Mare Adriatico sono risultati molto limitati. Le attività del progetto sono state condotte in tre fasi dove nella prima fase sono state studiate 2 spiagge per un anno con cadenza mensile. Nella seconda fase, 4 spiagge sono state studiate su base stagionale (tre volte). Nella terza fase sono state studiate 5 spiagge solo intorno alla stagione estiva per valutare l'impatto del turismo estivo. Nelle ultime 2 fasi del progetto, sono stati presi in considerazione anche i blocchi relativi al COVID-19 poiché l'uso delle spiagge era limitato. Differenze complessivamente significative sono state riscontrate tra la macrofauna appartenente a differenti taxa. Le differenze sono probabilmente legate alla differenza nel tipo di impatto in siti diversi. Complessivamente, nella maggior parte dei siti i bivalvi appartenenti principalmente a Lentidium mediterraneum sono risultati essere i taxa più dominanti nei siti colpiti. Nei siti con meno disturbi, Donax sp. è stato trovato più comunemente alludendo a una maggiore sensibilità ai disturbi umani. Il gasteropode Tritia neritea è risultato essere uno degli organismi resistenti alle perturbazioni in quanto raggiungevano il picco di abbondanza nel periodo più turistico. Inoltre, i crostacei come gli anfipodi sono stati trovati maggiormente in siti meno colpiti e/o stagioni/periodi meno colpiti, evidenziando il loro potenziale come indicatore di disturbi negli ecosistemi delle spiagge sabbiose. Sebbene, in ambiente naturale, potrebbe diventare più complesso separare un tipo di impatto su un determinato taxon da un altro, i nostri risultati possono indicare alcune informazioni riguardanti la sensibilità di un particolare taxa rispetto a un impatto specifico.
Sandy beaches are one of the most important spots that is not only sustaining biodiversity by providing habitat and food but also supporting human livelihood by providing socioeconomic opportunities. The increasing pressure on sandy beaches is leading to degradation of coastal ecosystem. To understand these threats and their impacts on the intertidal macrobenthic communities, this project was designed. Initially, data regarding certain human impacts was collected globally in the form of a systematic review to highlight the gaps. The data regarding impacts of anthropogenic disturbances on Adriatic Sea was found to be very limited. The activities of the project were conducted in three phases where 2 beaches were studied for one year on monthly basis in the first phase. In the second phase, 4 beaches were studies on seasonal basis (three times). In the third phase, 5 beaches were studied only around the summer season to evaluate the impact of the summer tourism. In the later 2 phases of the project, the COVID-19 related lockdowns were taken into account as well since the use of the beaches was limited. Overall significant differences were found among the macrofauna belonging to different taxa. The differences are possibly related to the difference in the type of impacts at different sites. Overall, at most of the sites bivalves mainly belonging to Lentidium mediterraneum was found to be the most dominant taxa at impacted sites. At sites with less disturbances, Donax sp. was found more commonly hinting about its sensitivity towards human disturbances. The gastropod specifically Tritia neritea was found to be one of the resistant organisms towards disturbances since they were peaking in abundance at the most touristic period. Furthermore, the crustaceans such as amphipod were found more at less impacted sites and/or less impacted seasons/periods, highlighting their potential as an indicator of disturbances in sandy beach ecosystems. Although, in natural environment, it could become more complex to segregate one type of impacts on a certain taxon from another, yet our detailed results can indicate some information regarding the sensitivity of a particular taxa towards a particular impact.

The distribution of zoobenthos communities in six small mountain streams of the northern macroslope of the Khamar-Daban Ridge in the district between the Baikalsk city and the village Murino was investigated. There are 16 taxonomic groups registered in the communities. The dominant groups are most often Oligochaeta, Chironomidae (larvae and pupae), endemic Amphipoda, larvae of Trichoptera and Planariidae. The largest macrozoobenthos biomass was observed in ripal zone of the streams on heavily silted grounds, and the smallest – on sandy grounds with an admixture of silt and detritus at the fairly fast flow.
