  • Effects of the exotic rotifer Kellicottia bostoniensis (Rousselet, 1908)
           on the microbial food web components
    • Abstract: Abstract Species introduction can alter the structure and dynamics of biological communities and, therefore, understanding their feeding behavior and the effects that an exotic species can cause in the food web configuration is pivotal. We aimed to experimentally investigate the effects of the potential invasive species Kellicottia bostoniensis on different components of the microbial food web and to evaluate if the food preferences of this species change under different conditions of resource availability and interspecific interactions. We tested the hypothesis that the presence of K. bostoniensis would have direct and indirect effects on the different components of the planktonic food web. We designed three different assays (E) using prey size fractionation, being E1 composed of bacteria (HB) and picophytoplankton (PPP), E2 composed of HB, PPP and autotrophic and heterotrophic flagellates and, E3 with the whole planktonic community. Each one composed of a control in the absence of K. bostoniensis and a treatment with the presence of this species. Results showed that K. bostoniensis caused direct effects on its main food items, the heterotrophic and autotrophic flagellates, whereas no evidence of indirect effects was observed on the base components of the microbial web food, such as heterotrophic bacteria and picophytoplankton. In addition, a negative effect of the exotic rotifer on ciliates was observed. Finally, we emphasize that the impact of K. bostoniensis on aquatic ecosystem may be quite harmful, since this specie can act as a sink of matter and energy to higher trophic levels.

  • Spatial variation in the feeding strategies of Mediterranean fish:
           flatfish and mullet in the Gulf of Gaeta (Italy)
    • Abstract: Abstract Marine coastal areas are highly productive due to the presence of various inputs of organic matter, including terrestrial material, which fuels food webs. However, the ecological mechanisms underlying the productivity of benthic and demersal fish species in estuarine areas are poorly understood. By means of C and N stable isotope analysis and Bayesian mixing models, we investigated the trophic niches of three common fish species: Citharus linguatula, Pegusa lascaris (flatfish) and Liza ramada (mullet) in the Gulf of Gaeta (Italy). Fish were collected from the north-western area and the south-eastern area of the Gulf of Gaeta, the latter affected by organic inputs from the Garigliano River. The results highlighted the riverine terrestrial origin of the organic matter at the base of the food web in the south-eastern area and marine autochthonous input in the north-western area. All fish species increased their trophic specialisation in proximity to the river mouth. L. ramada specialised on seston of terrestrial origin, reducing its niche overlap with C. linguatula and P. lascaris. Away from the river mouth, all species were characterised by longer individuals, increased intraspecific diet variability and higher interspecific similarity in resource use. Organic input from the river represented a complementary trophic niche axis that enabled lower interspecific niche overlap in the south-eastern area, where fish populations were found at higher densities. In conclusion, this study provided information about the effects of the flow of material from the basal compartment up to abundant fish species in areas enriched by organic matter of varying origin.

  • How far may life venture' Observations on the harpacticoid copepod
           Phyllognathopus viguieri under extreme stress conditions
    • Abstract: Abstract The authors report the first finding of living specimens of the harpacticoid copepod Phyllognathopus viguieri (Maupas, 1892) in the gut content of the teleost fish Merluccius merluccius (Linnaeus, 1758), and their extraordinary viability after the M. merluccius specimens had been stored at − 20 °C for more than 1 month and their stomachs been preserved in 70% ethanol for a further month. After their survival for such a long time in such harsh conditions, P. viguieri, after a few minutes of total immobilization, began to swim actively and fast, and after being reared in freshwater or seawater in Petri dishes under starvation, these animals reproduced, and the presence of nauplii, copepodids and adults which completed the whole life cycle in 3/5 days was observed in freshwater and seawater, respectively. The occurrence of P. viguieri in the stomach of a true marine demersal fish species enlarges the known habitat types the species may stably colonize. The potential for dormancy in fertilized adult females to escape adverse environmental conditions is hypothesized.

  • Impacts of ocean acidification on hermit crab communities through
           contrasting responses of Pagurus filholi (de Man, 1887) and Clibanarius
           virescens (Krauss, 1843)
    • Abstract: Abstract Ocean acidification (OA) is predicted to decrease the abundance of calcified organisms such as gastropods. Since hermit crabs utilize gastropod shell as mobile shelter, OA has indirect impacts on hermit crab population. To examine the impacts of OA on hermit crab communities, which use calcified shell as the mobile shelter, we conducted field surveys and laboratory experiments using volcanic CO2 seeps in Shikine Island, Japan. By comparing hermit crab community structures and shell availability among five intertidal rocky shores with different degrees of acidification, Paguroidea abundance and species richness were simplified in acidified areas. Rearing experiments comparing survival rates of two Paguroidea species, Pagurus filholi (de Man, 1887) and Clibanarius virescens (Krauss, 1843), at both adult and larval stages, between acidified and ambient aquaria revealed that acidified seawater reduced larval survival rate of C. virescens. Overall, the results indicated that the species-specific direct effect in elevated C. virescens larval mortality could simplify the Paguroidea species composition. In addition, such direct effect would also lead to reduction of Paguroidea abundance, along with indirect effects though a decrease in shell availability.

    • Abstract: Abstract Studies on the trophic ecology of fish have revealed considerable alimentary plasticity for the majority of ichthyofauna in tropical rivers. This leads to the prediction that diet reflects the availability of food in the environment, namely seasonal variation in the abundance and type of food resources. To examine this, we assess: (1) seasonal variation in the diet and trophic structure of assemblages of benthic fish inhabiting the main channel of a large floodplain river in the Brazilian Amazon, (2) seasonal changes in the availability of food resources, (3) the trophic response (food selectivity) of benthic species in relation to food availability and (4) niche overlap among benthic species. Data were collected during 2 rising and 2 receding phases. Aquatic insects, plant matter and detritus were the predominant items in the diet of assemblages of benthic fish. The majority of fish species changed their diet between seasons. The diets of Exallodontus aguanai and Sternarchella calhamazon were studied in detail and showed positive correlation with food resource availability. Feeding selectivity varied among seasons for these two species. Niche overlap between these two species was observed during only one receding season. Our results reveal the importance of aquatic insects in the predominantly omnivorous diet of the benthic fish assemblages. Trophic plasticity was also evident, possibly because of the seasonal availability of food items. These results underline the role that organic matter derived from floodplains plays in this aquatic system which is characterised as having naturally low autochthonous productivity.

  • On the environmental background of aquatic organisms for ecological niche
           modeling: a call for caution
    • Abstract: Abstract Ecological niche modeling (ENM) is a technique widely used in many disciplines of science. Recently, the extent of using the environmental background for ENM calibration has been pointed out as playing a crucial role in determining model outcomes. However, when modeling freshwater species, the need for a background refinement has been ignored and its consideration possesses important implications not taken into account before. Here, using Maxent algorithm and global occurrence data characterizing the distribution of the invasive freshwater turtle, Trachemys scripta, we performed ENM transfer and compared native and invasive niche estimates for the species in the environmental space. We used two environmental backgrounds: (a) a traditional area, based on the current distribution and dispersal capacity of the species, and (b) a more restricted area, which corresponds exclusively to freshwater bodies. Our analysis revealed strong differences between the traditional and the restricted backgrounds in niche transferability, with differences in Maxent probability values ranging from − 0.59 to 0.41. Also, during comparisons between native and invasive niches, the niches were more similar when the traditional approach was used, compared to the restricted approach. Our results highlight the importance of considering the biological restriction of the species when establishing the extent of the background in ecological niche modeling; in this case, a more restricted area represented by freshwater environments.

  • Water bears dominated cryoconite hole ecosystems: densities, habitat
           preferences and physiological adaptations of Tardigrada on an alpine
    • Abstract: Abstract We investigated the Forni Glacier and the surrounding area in the Alps in terms of habitat preferences, densities, dispersal and desiccation tolerance of glacier tardigrades, which are one of the most common faunal representatives and top consumers in supraglacial ecosystems. To do so, we sampled supraglacial environments (cryoconite holes, debris from ice surface, dirt cones and moraine, mosses from supraglacial stones) and non-glacial habitats (mosses, freshwater sediments and algae), and we installed air traps on the glacier and the nearby area. We found that cryoconite holes on the Forni Glacier are exclusively dominated by one metazoan group of tardigrades, representing one species, Hypsibius klebelsbergi (identified by morphological and molecular approaches). Tardigrades were found in 100% of cryoconite holes and wet supraglacial sediment samples and reached up to 172 ind./ml. Additionally, we found glacier tardigrades in debris from dirt cones and sparsely in supraglacial mosses. Glacier tardigrades were absent from freshwater and terrestrial samples collected from non-glacial habitats. Despite the fact that H. klebelsbergi is a typical aquatic species, we showed it withstands desiccation in sediments, but in low temperatures only. Treatments conducted in higher temperatures and water only showed low or no recovery. We suspect successful dispersal with wind might have taken place only when tardigrades desiccated in sediments and were passively transported by cold wind. Limited ability to withstand high temperatures and desiccation may be potential barriers preventing glacier tardigrades inhabiting new, even apparently suitable high mountain water bodies like temporary rock pools.

  • Occurrence and habitat use of European eel ( Anguilla anguilla ) in
           running waters: lessons for improved monitoring, habitat restoration and
    • Abstract: Abstract To improve the management of the European eel (Anguilla anguilla) in freshwater, it is essential to define important lotic habitats. Electrofishing data from 289 wadeable, hard-bottom sites in 69 Swedish coastal rivers and streams, originally surveyed for salmonid monitoring, were used to evaluate the effects of sampling- and habitat-related factors on eel occurrence. Probability of eel occurrence, as influenced by sampling procedure (sampled area, number of consecutive runs and ambient water temperature) and habitat characteristics (size of catchment, dominating bottom substrate, shade, water velocity, mean depth), was evaluated for small (total length ≤ 150 mm) and large (> 150 mm) yellow eels. Data were analysed in a mixed presence/absence generalized linear model with dispersal (distance to mouth from sampled site), habitat and sampling-related variables as covariates. The two models explained variation in occurrence to 81.5% for small eel and 76.2% for large eel. Probability of eel occurrence decreased with distance from the river mouth, and increased with sampled area, number of runs, water temperature, coarser substrate and size of river. We suggest that future eel habitat restoration should focus on lower reaches of larger rivers with suitable coarse bottom habitats. Stocking of young eel should be carried out in comparable accessible habitats in the upper reaches where eel densities are low. The results also strongly indicate that eel may be sampled together with young salmonids with DC electrofishing in wadeable habitats.

  • Hierarchy of factors controls denitrification rates in temperate
           intermittently closed and open coastal lakes/lagoons (ICOLLS)
    • Abstract: Abstract Intermittently closed and open lakes/lagoons (ICOLLs) can occur in alternate stable states: clear and turbid, with nitrogen inputs from high-intensity agricultural land use often fuelling phytoplankton growth in ICOLLs. Due to their limited water exchange, ICOLLs are particularly susceptible to eutrophication. In these environments, denitrification may remove a substantial proportion of the land-derived nitrogen load, reducing their vulnerability to eutrophication; however, the factors that influence denitrification in ICOLLs are poorly understood. In this study, we addressed the relative importance of physico-chemical and biotic factors related to nitrate-saturated denitrification rates (including temperature, nutrient/organic matter supply, oxygen conditions, sediment type and benthic macroinvertebrates) in two eutrophic ICOLL ecosystems: one supports some submerged macrophytes, while the other is in a persistent, turbid, phytoplankton-dominated system. Flexible in situ enclosures and denitrification enzyme assay measurements were employed to determine denitrification rates in response to new nitrate pulses, which are commonly observed in these systems. In situ denitrification rates were inhibited in both ICOLLs in winter, whereas in summer they were positively correlated with organic matter availability. Denitrification rates were greater in the shallow, marginal sediments of the ICOLLs. Bioturbating macrofauna significantly enhanced in situ sediment oxygenation and probably transported sediment organic carbon and nitrate simultaneously to sites of denitrification at the sediment oxic–anoxic interface. Our study found that nitrate-saturated sediment denitrification rates were controlled by a hierarchy of temporally and spatially structured physico-chemical and biotic factors in the following order of importance: temperature → organic matter availability → water depth → bioturbation.

  • The status and potential distribution of Hydrocotyle umbellata L. and
           Salvinia auriculata Aubl. under climate change scenarios
    • Abstract: Abstract Aquatic ecosystems are susceptible to human-induced disturbance, including climate changes and biological invasions. The aim of this study was to assess the current and future potential distribution of two introduced aquatic species that have become invasive in some places where they were introduced. Hydrocotyle umbellata L. and Salvinia auriculata Aubl. are free-floating macrophytes native to North, Central, and South America. Both can quickly colonize aquatic environments because of their high growth rate and reproductive capacity similar to water hyacinth. Both species were introduced to Egypt for ornamental purposes. We have applied species distribution models using the Maxent approach and bioclimatic variables. Occurrence records from the entire range of the two species were obtained from the Global Biodiversity Information Facility and used for modelling their habitat suitability and assessing the potentiality of their spread in other new habitats. To project future changes in the two macrophytes’ distributions with respect to climate change, we used four representative concentration pathway scenarios (RCP 2.6, 4.5, 6.0 and 8.5) of the IPCC 5th assessment, based on different assumptions of greenhouse gas emissions for the future period of 2050s. The results showed that Maxent approach has successfully predicted the distribution of the two species with test AUC > 0.92. Bioclimatic variables that contributed the most to the prediction of the two species distribution included isothermality, temperature seasonality, mean temperature of the coldest quarter, and minimum temperature of the coldest month. Results showed that the range of S. auriculata is predicted to increase by 2050 under all climatic scenarios. A decline in the current climatically suitable habitats of H. umbellata is projected to occur in its native range, especially in South America, while it is predicted to gain more suitable habitats out of its native range in Europe and Africa. Both species are predicted to gain habitats outside their native range, while their ranges are expected to face a decline in their native region. The study can help in the identification of areas with high potential vulnerability to future invasions by the two studied aquatic macrophytes and thus can assist in prioritization of monitoring actions and management plans. This can reduce any ecological and socio-economic consequences due to invasion by these two aquatic plants.

  • Mesohabitat current velocity effects on Didymosphenia geminata and
           macroinvertebrates in a SE USA hypolimnetic tailwater
    • Abstract: Abstract The diatom Didymosphenia geminata is known to alter benthic habitat and macroinvertebrate diversity and community structure. Associations between macroinvertebrate communities and D. geminata biomass in riffle and run mesohabitats were investigated in the South Fork Holston River in Tennessee and Virginia, USA. We found that low current velocity, low turbidity, and high dissolved oxygen (DO) were strong predictors of D. geminata mat presence. Didymosphenia geminata ash-free dry mass was significantly higher in run mesohabitats with low current velocity (CV) than in riffle mesohabitats with higher CV. Macroinvertebrate alpha diversity (Shannon Diversity H’) was only marginally significantly different between riffle and runs, while beta diversity (community composition) was highly significantly different between these mesohabitats. NMDS analyses found that D. geminata was a relatively unimportant predictor of changes in community structure relative to specific conductance, CV, DO, and turbidity. However, effects of D. geminata on macroinvertebrates appear to be very taxon specific with effects on individual taxa potentially masked by tailwater effects on general macroinvertebrate diversity in global analyses. We observed that taxon-specific effects include, but are not limited to, (1) reduction of bryophyte microhabitat utilized by dominant ephemeropterans, trichopterans, amphipods, coleopterans, and some chironomid genera in run mesohabitats from competition with D. geminata for substrate attachment space; and (2) differences in utilization of D. geminata mat biomass as a food resource and microhabitat for chironomids. Our insights into taxon-specific effects of D. geminata on macroinvertebrates open up multiple avenues for experimentation in which to validate our observational findings.

  • Influence of abiotic factors on the composition and abundance of aquatic
           ferns occurring in the state of Paraíba, Brazil
    • Abstract: Abstract Aquatic ecosystems are influenced by water quality and the surrounding environment, and changes to such ecosystems exert an effect on species. The aim of the present study was to relate the composition/abundance of species of aquatic ferns to both abiotic factors of water quality (total phosphorus and chlorophyll a) and the characteristics of the surrounding environment (rural, urban and vegetation). We analyzed 53 aquatic ecosystems in the state of Paraíba with lentic characteristics, considering total phosphorus and chlorophyll a as well as the classification of land use and occupation in the surrounding areas. We recorded nine species of aquatic ferns, which demonstrated a preference for environments with good water quality (low concentration of chlorophyll a) as well as sensitivity to rural and urban activities. The individual analysis of the species revealed that abiotic factors exerted an influence on the occurrence and abundance of the species. Cyclosorus interruptus (Willd.) H. Ito proved to be resistant to impacted environments, whereas Marsilea sp. and Ceratopteris thalictroides (L.) Brongn proved to be bioindicators of water quality. Our study revealed species considered bioindicators of good water quality and identified changes in the composition/abundance of the species in relation to different land uses.

  • Allelopathic effects and potential active substances of Ceratophyllum
           demersum L. on Chlorella vulgaris Beij.
    • Abstract: Abstract Morphological responses of green algae to submerged macrophytes were rarely studied, and the potential active substances played roles in the interaction were little known previously. In the current work, according to acetone extract experiments, it was demonstrated that submerged macrophytes (Ceratophyllum demersum L.) could allelopathically inhibit the growth of Chlorella vulgaris Beij. and induce its colony formation, the effects of which were concentration dependent. Gas chromatography–mass spectrometry analysis revealed eight kinds of active substances from the C. demersum extracts, namely hexanoic acid, phthalic acid, octanedioic acid, butenoic acid, azelaic acid, palmitic acid, alpha linolenic acid and pentanedioic acid. Standard compound addition test indicated that palmitic acid and alpha linolenic acid might play important roles in the induction of colony formation and growth inhibition of C. vulgaris. This study provided some more new insights into the photosynthetic organism interaction between submerged macrophytes and green algae, in terms of not only growth but also morphological responses.

  • Looking for environmental and endocrine factors inducing the
           transformation of Sicyopterus lagocephalus (Pallas 1770) (Teleostei:
           Gobiidae: Sicydiinae) freshwater prolarvae into marine larvae
    • Abstract: Abstract During their ontogenetic development, many species of fishes undergo drastic changes which may be defined as true metamorphosis when they are induced by thyroid hormones. Sicyopterus lagocephalus is an amphidromous goby that has to change biome twice during its life cycle. The first biome shift occurs few hours after hatching in the river. The aim of the present study is to determine what external/environmental and internal/endocrine factors induce the transformation of freshwater prolarvae into marine larvae. First, we experimentally determined that the minimum salinity threshold inducing the transformation of all the prolarvae into marine larvae is 1.5, whereas a salinity of 0.2 induces the transformation of a few prolarvae. Similarly, an 18-h immersion in seawater before the return to freshwater is enough to induce the transformation of all the prolarvae into marine larvae, even though an immersion for 3 h can induce the transformation of a few prolarvae. Furthermore, we demonstrated that a simulated increase in the osmotic pressure of freshwater does not trigger the transformation of the prolarvae into marine larvae. Our study also reveals that among the various constituent salts of seawater, it is primarily NaCl and K+ that induce the transformation of the prolarvae, leading to the assumption that the membrane protein Na+/K+-ATPase is activated simultaneously with the prolarval transformation. Finally, we showed that thyroid hormones and cortisol are not involved in the prolarval transformation, leading to the conclusion that this first transformation in the life cycle of S. lagocephalus cannot be considered as a true metamorphosis.

  • Assessing multiple predator, diurnal and search area effects on predatory
           impacts by ephemeral wetland specialist copepods
    • Abstract: Abstract Predator–prey interaction strengths can be highly context-dependent. In particular, multiple predator effects (MPEs), variations in predator sex and physical habitat characteristics may affect prey consumption rates and thus the persistence of lower trophic groups. Ephemeral wetlands are transient ecosystems in which predatory copepods can be numerically dominant. We examine the interaction strengths of a specialist copepod Paradiaptomus lamellatus towards mosquito prey in the presence of conspecifics using a functional response approach. Further, we examine sex variability in predation rates of P. lamellatus under circadian and surface area variations. Then, we assess the influence of a co-occurring heterospecific predatory copepod, Lovenula raynerae, on total predation rates. We demonstrate MPEs on consumption, with antagonism between conspecific P. lamellatus predatory units evident, irrespective of prey density. Furthermore, we show differences between sexes in interaction strengths, with female P. lamellatus significantly more voracious than males, irrespective of time of day and experimental arena surface area. Predation rates by P. lamellatus were significantly lower than the heterospecific calanoid copepod L. raynerae, whilst heterospecific copepod groups exhibited the greatest predatory impact. Our results provide insights into the predation dynamics by specialist copepods, wherein species density, diversity and sex affect interaction strengths. In turn, this may influence population-level persistence of lower trophic groups under shifting copepod predator composition.

  • Fluctuating asymmetry of adult Chinook Salmon ( Oncorhynchus tshawytscha )
           otoliths from wild and hatchery origins
    • Abstract: Abstract Fluctuating asymmetry is the non-directional deviations from bilateral symmetry and occurs across organisms. Fish otoliths are often used to test for differences in symmetry as otoliths aid in hearing, homing, and balance. Here, we evaluated the symmetry of otolith pairs in adult Chinook Salmon between wild and hatchery-origin stocks. Pacific salmon are economically and ecologically important to the Pacific Northwest, USA. Chinook Salmon are widely distributed throughout the North Pacific Ocean, yet several wild populations are federally listed as endangered or threatened due to depleted stocks, loss of genetic diversity, and hatchery contribution to wild stocks. As such, fishery managers are concerned with the health and condition of hatchery-origin fish and their impacts on wild populations. We included both hatchery and wild-origin Chinook Salmon from the Coast Mountain and Willamette regions in Oregon as well as hatchery populations from southeast Alaska. We evaluated several metrics to test shape variation and symmetry between the left and right sagittal otoliths. We found consistently more asymmetry in otoliths from hatchery origin than wild Chinook Salmon within seven out of eight total metrics. These results could have conservation and management implications as hatchery-origin Chinook Salmon can reduce pressure from wild stocks while continuing to support commercial and recreational industries.

  • Strategies of phosphorus utilization in an astaxanthin-producing green
           alga Haematococcus pluvialis , a comparison with a bloom-forming
           cyanobacterium Microcystis wesenbergii
    • Abstract: Abstract Haematococcus pluvialis is a unicellular green alga with great commercial value, due to its synthesis of powerful antioxidant astaxanthin. H. pluvialis was mainly distributed in small water bodies but was also observed in eutrophicated lakes, and even coexisted with Microcystis. However, Haematococcus cells never prevail in eutrophicated water bodies. Phosphorus is the main limiting factor in most aquatic ecosystems and may have a role in the distribution of H. pluvialis. Here, we focused on the physiological responses of H. pluvialis to various phosphorus conditions (0.002, 0.02, 0.2, and 2 mM), and compared with a bloom-forming cyanobacterium Microcystis wesenbergii. Growth determination suggested that high phosphorus conditions (0.2 mM and 2 mM) favor the growth of H. pluvialis cells, but H. pluvialis cells have a shorter duration of log phase than M. wesenbergii cells. Growth determination also indicated H. pluvialis cells had lower tolerability to low phosphorus (0.002 mM). Qualitative comparisons from long-term and short-term phosphorus uptake experiments, polyphosphate accumulation and extracellular alkaline phosphatase expression analysis suggested two different phosphorus utilization strategies in the two species. H. pluvialis cells were characterized with the induction of extracellular alkaline phosphatase to survive phosphorus-deficient condition, while M. wesenbergii cells were characterized with quick uptake of phosphorus and accumulation more of polyphosphate in phosphorus-replete conditions. To our knowledge, this is the first study to demonstrate features of phosphorus uptake and utilization in H. pluvialis, which will increase our understanding in the distribution of H. pluvialis.

  • Growth and age of the midget octopus, Octopus huttoni
    • Abstract: Abstract The midget octopus Octopus huttoni is an important link between trophic levels as a food source and a predator, but little is known about its life history or growth. This is the first study to age and quantify growth in O. huttoni from three populations in Southern New Zealand, namely Foveaux Strait, Otago Harbour, and the Otago continental shelf. Morphometries were measured for 121 individuals, ages were estimated for 109 individuals using beak and stylet increment analysis, and lipofuscin quantity was analysed for 106 individuals. Assuming that one increment equals 1 day, beaks provided the highest age estimate (up to 250 days), but are suspected to be an underestimate (40–70 days) because increments were not found on laboratory-reared paralarval beaks, suggesting that the first increment may form after settlement. Daily growth rings in stylets were validated by tetracycline marking, but low estimates of age were attributed to poor visualisation of the stylet nucleus. The relationships between lipofuscin volume ratio and age or size of the individual were not significant, lipofuscin density was low, and individual variation was high. Results indicated that this species displays indeterminate growth until death, with a maximum mantle length of 50–60 mm at an age of 200–250 days. Further, individuals from Foveaux Strait were smaller and younger than those found in the Otago Harbour, supporting an hypothesis of an ontogenetic migration onshore.

  • Molecular characterization and phylogenetics of Indian polychaete fauna:
           scope for implementation in ecological monitoring
    • Abstract: Abstract DNA barcodes are increasingly applied to ascertain the taxonomic identification to improve the speed and accuracy of ecological monitoring programmes. The success of integrating molecular approach in routine surveys ultimately depends on the coverage of reference libraries that require constant upgradation. The present molecular study was aimed at strengthening the genetic database of Polychaeta, which at present is poorly constructed. The current effort is first of its kind that covered a large geographical area along the northwest India. The study has contributed in building a comprehensive COI database of polychaete taxocene that included new records of one family, four genera and six species. The phylogenetic analysis revealed presence of 19 distinct clades, each comprising of individual family with studied polychaete species and conspecific/congeneric reference sequences. This is the first analysis that revealed a close relationship between Longosomatidae and Cirratulidae, rather than Spioniform polychaetes. Thus, the phylogenetic information was useful in distinguishing the polychaete species in the study region. Molecular analysis also facilitated the identification of potentially new Streblospio sp. that displayed close morphological as well as genetic affinity with S. gynobranchiata, with an inter-specific distance of 0.11. The present study proves the effectiveness of molecular characterization and phylogenetics in delineating the Indian polychaete species complex for ecological monitoring. The reference database can aid the high-throughput biomonitoring programmes in future.
