Contenido intestinal, solapamiento de nichos, Chironominae, Tanypodinae. A complete linkage dendrogram was obtained and signifcant clusters (dietary patterns) were identifed. This heterogeneity is clearly demonstrated by benthic studies in the main channel of the Paraná River and in the lotic and lentic components of its flood plain. The results from the evaluation using the BMWP’ index do not present the real conditions of the watersheds, which suggests a review of the evaluation method. Lewis et al. & POI DE NEIFF, A. Six functional feeding group (FFG) indices applied in ecological assessment were tested for their accuracy in detecting impairment in 12 cases of disturbance on 11 streams in south-western Germany. Functional richness patterns of lake chironomid assemblages have been increasingly studied in the Northern Hemisphere, but so far there are no studies in Southern Hemisphere lakes. Among them stand out the Bivalves and the order Diptera (Chironomidae family), El enfoque metacomunitario constituye una perspectiva apropiada para abordar el estudio de los sistemas fluviales con llanura aluvial en los cuales la conectividad hidrológica es un proceso fundame, This thesis project postulates that “benthic macroinvertebrates assemblages will provide a diagnosis about ecological integrity of the Dulce River fluvial system, through their structure and specie, We are an interdisciplinary group at the Instituto Nacional de Limnología (INALI, Argentina) gathering by our interest in metacommunities. The stress value obtained for the 2D NMDS plot, indicated that a good ordination was obtained for the overall structure of data corresponding to the diet of chironomids. Composition, community structure and func tional organization A total of 60 taxa, mostly belonging to Diptera-Chironomidae (24), Oligochaeta (15) and Ephemeroptera (3) SANDY BOTTOM MACROINVERTEBRATES IN THE RIVER TREIA 289 CampagnanosX Fig. Diptera Chironomidae. Food items obtained from the gut content analysis of Endotribelos sp., Phaenopsectra sp., Chironomus gr. Therefore, shredders break and condition leaves favouring the colonization of processed detritus by microorganisms and other invertebrates, while scrapers consume algae and microbes attached to the coarse particulate organic matter (CPOM) (MAGEE, 1993). 28.2%, animal tissues 4.4% and algae 1.4%. The food organisms were dominated by midges (Diptera: Tendipedidae); by … other large rivers, are still scarcely known. The American Naturalist 101:377-385. Suspension feeders transform massive amounts of seston in large northern rivers. A review of world literature shows that progress in stream ecology has been substantial over the past three decades, with studies focused mainly on the holistic character of these Food (larvae of Ephemeroptera, Simuliidae, and Chironomidae) was provided in excess. Diet was composed mainly by amorphous matter, invertebrate remains, inorganic matter and unicellular algae. within detritivores and a higher similarity among the, the 2D NMDS plot, indicated that a good ordination was, obtained for the overall structure of data corresponding, to the diet of chironomids. Functional feeding groups are a classification approach that is based on behavioral mechanisms of food acquisition rather than taxonomic group. 2015). may also be analyzed through the degree of niche overlap, between species. Moreover, predators consume animals or some of their parts. [ Links ], GRAÇA, M. A. S. 2001. Chironomidae larvae were identified to the lowest taxonomic level possible using available keys (Wiederholm 1983; Epler 2001; Paggi 2009). Although chironomids have been used extensively in paleoclimatic and paleoenvironmental research, they are rarely used for paleoenvironmental reconstructions of the Pampean shallow lakes. y Procladius sp. Ingestion was determined from production estimates, bioenergetic efficiencies, and quantitative gut analyses. PRIMER-E® software Change in Marine Communities, an approach to statistical analysis and interpretation. use detritus as their main food source in coincidence, individuals of the same genus acted as predators. [ Links ], MERRIT, R. W. & CUMMINS, K. W. 1984. decorus sp. Trichoptera larvae display a diversity of trophic adaptations and exploit a variety of microhabitats, but information on their feeding habits in the Neotropical region is still incomplete. A quantitative food web showed that while the linkages among nine taxa were complex, the ingestion pathways were dominated by amorphous detritus (total consumption = 62.5 g.m(-2).yr(-1)) and animal prey (22.3 g.m(-2).yr(-1)), with >99% of food resources being consumed by the three dominant filter-feeding taxa. Annual Review of Entomology 18:183-206. (2006); TOMANOVA et al. Fish and Wildlife Leaflet 13(3):1-7.

(2002) ii June 2002 It is my belief that the philosophy of “Think Globally, Act Locally” has been fed primarily on animal tissues (mainly, Phaenopsectra>Endotribelos>Polypedilum>Ch, sp. The relative importance of fungi and invertebrates in the decomposition process depends upon the density of shredders, which, in turn, may depend on litter accumulation in streams. (Tanypodinae) el ítem más importante fue tejido animal (principalmente restos de oligoquetos). We examined the relationships of functional feeding groups, feeding strategies, body size, and the morphological adaptations of chironomid larvae with the environmental quality of 94 sites. These results coincide closely with those obtained in a tropic area by Henriques-Oliveira et al. Interactions between species and with, their environment, the life history strategies, and their, ecologic role determine the structure of communities, the, species diversity, the relative abundance of or. Thus, Hyalella curvispina is defined The entomological material was fixed with 4 % formol and preserved in 70 % ethanol. Food items obtained from the gut content analysis of. [ Links ], DEATH, R.

The niche concept revisited: mechanistic models. Leaves were collected at abscission and 6 g dry weights were placed in 5mm mesh nylon bags. Among the categories of functional feeding groups are: i) shredders that consume wood and leaf litter; ii) collectors that consume decomposing vascular plants and fine particulate organic matter (FPOM); … [ Links ], TOKESHI, M. 1999. Principal component analysis (PCA) on log (x + 1) transformed data was used to examine variation in physical and chemical parameters between sites and season. showed no pattern. ; thus, in this study the genus showed a better use of the resources. Gayana 70(2):206-209. [ Links ], MALMQVIST, B.; WOTTON R. S. & ZHANG, Y. X. functional feeding groups is usually based on classifications carried En este sentido, nuestra hipótesis es que los sistemas fluviales aluviales están regidos por mecanismos que operan a nivel local (como los filtros ambientales o la competencia) y regional (como la dispersión), modulados en primera instancia por las fluctuaciones hidrológicas que ocurren aperiódicamente en el sistema. El principal ítem alimentario encontrado en, tejido animal (principalmente restos de oligoquetos). & DRAGO, E. 2002. Dietary overlap was calculated for all pairs of genera. Ecology letters 10:1-9. Greatest reductions in activity occurred at low levels of fish presence; above a certain level further increases in fish presence had little effect on activity.2. Diet and functional feeding groups of Chironomidae (Diptera)... the Middle Paraná River. This preference may be the result of changes in leaf matrix carried out by the microbial community or the presence of fungal hyphae with a higher nutrition value than the leaves themselves. Date of Publication. Our research addresses the study of ecological processes d, Abstract We have studied some aspects of Besdolus ravizzarum biology in the Apennines. These results were compared with the widely used categories of MERRIT & CUMMINS (1984). The results suggest that rice field spiders are supported by three different carbon pools: (1) aquatic carbon originating from algae and (2) legacy carbon from previous growing cycles, both incorporated via between-season predation on gnats and midges, and (3) carbon from the current rice season incorporated via herbivore prey. Keywords : Sandy bottom, macroinvertebrates, community structure, functional feeding groups, moderate pollution, river. The food contained in the guts was assumed as the 100% and the proportions of the different types of food were estimated using an eyepiece micrometer scale of 10 x 10 (CHESHIRE et al., 2005).

Brazilian Journal Biology 64(4):809-817. Indeed, the, partitioning of resources amongst closely related species, as a structuring force for communities has been a central, theme in the development of modern ecology (, in the aquatic food webs as they process basal resources, that are transferred to the higher trophic levels. Benthic Macroinvertebrates in Freshwaters-Taxa Tolerance Values, Metrics, and Protocols Mandaville, S.M. Se utilizaron 192 bolsas con 5 g de hojas senescentes de las especies seleccionadas y de una mezcla (1:1), y se extrajeron cuatro réplicas por punto de muestreo en tiempos predeterminados (+3, 7, 15, 30, 45, 60, 75 y 90 días). Predators had a lower niche overlap, while the lowest value was obtained for Procladius sp. IIInstituto Nacional de Limnología (INALI-CONICET-UNL), Ciudad Universitaria (3000) Santa Fe, Argentina. The gut contents of nine genera of benthic Chironominae and Tanypodinae from the Middle Paraná River floodplain habitats (a lake and a secondary channel) were analyzed to determine their feeding patterns and functional feeding groups. The secondary aim is to explore the possibility of competitive interactions between the species, which is an issue that has rarely been investigated in Chironomidae (Armitage et al. Diet and functional feeding groups of Chironomidae (Diptera) in the Middle Paraná River floodplain (Argentina) By M. Celeste Galizzi, Florencia Zilli and Mercedes Marchese. Niche overlap was calculated using Pianka's Index (PIANKA, 1973, 1974), using EcoSim, 7.0 Version (GOTELLI & ENTSMINGER, 2001). Niche overlap and diffusion competition. Celeste Zilli, Florencia Marchese,Mercedes . Chironomidae larvae were identified to the lowest taxonomic level possible using available keys (Wiederholm 1983; Epler 2001; Paggi 2009). Plant matter comprised pine pollen, conidia of fungi, cyanobacteria, green algae and diatoms. For the functional feeding groups, there were significantly higher relative abundances of grazers and filterers in unburned rivers, and more predators in burned rivers.

This classification has the advantage of combining morphological characteristics (e.g., mouth part specializa-tion) and behavioral mechanisms (e.g., way of feeding) used by macroinvertebrates when consuming resources. Aquatic Botany 40:185-193. (1993); ROSI-MARSHALL & WALLACE (2002); HENRIQUES-OLIVEIRA et al. Feeding Ecology of two Plecopterans in low order Andean - Patagonian streams. Larvae of Chironomus tentans Fab, decreased the amount of time they spent outside their tubes as the presence of predatory pumpkinseed sunfish (Lepomis gibbosus L.) increased. The decomposition of Salix humboldtiana leaf litter and its colonization by invertebrates were studied in a secondary channel of the Middle Paraná River. This is the first study of chironomids from surface sediments from the central temperate plains of Argentina, and our records extend the ecological information of the Diptera in temperate areas. 1990.
