ABSTRACT We collected rotifers during one year (2002–2003) from four different sites in Lake Xochimilco and analyzed the species diversity. found on an average 25–30 co-existing at any site, rotifer density was highest summer months. The common genera throughout were Brachionus, Keratella, Polyarthra, Trichocerca, Filinia Asplanchna, we often six to eight of Brachionus same sample. Keratella cochlearis K. tropica together, as Trichocerca similis, T. pusilla cylindrica. genus Asplanchna...
Microplastics (MPs) are emerging pollutants that ubiquitous in aquatic ecosystems and can affect the stability of food webs. They intentionally produced a size less than 5 mm for specific purposes or result fragmentation larger plastic debris. Zooplankton be affected directly by ingestion MPs indirectly interference caused suspended particles. Various environmental agencies recommend genus Moina assessing risk from water pollutants. However, this has received attention research compared to...
Mangrove wetlands provide many ecosystem services and support biodiversity. The diversity of epifauna on mangrove roots has not yet been well characterized in regions compared to other faunal groups, despite its importance for energy transfer. aim this study was integrate update the taxonomic list fauna associated with submerged red mangrove, Rhizophora mangle , fill an existing gap characterization mangroves Colombian Caribbean. A total 43 bibliographic sources met search criteria, from...

The occurrence of cyanobacterial blooms is a characteristic eutrophic inland water bodies. Valle de Bravo reservoir (Mexico State, Mexico) the main source for Cutzamala Hydraulic System, which supplies drinking to west Mexico City (~6 million consumers) and suburban areas State. goal this study was determine presence microcystins (MC-LR equivalents) their relationship with toxic populations cyanobacteria recorded some years ago in important reservoir. We measured concentration MC-LR...
<p>Lake Xochimilco is a eutrophic water body in Mexico City used by the local population for aquaculture and agriculture. Water level maintained with inputs of partially treated waste from Cerro de la Estrella treatment plant. In this study we analysed quality at two sites Lake Xochimilco, Xaltocan Santa Cruz Canal using various indicators such as zooplankton diversity, saprobic indices, bacterial concentrations physico-chemical variables. Eighty litres was filtered each site, once...
Under the auspices of Organic Analysis Working Group (OAWG) Comité Consultatif pour la Quantité de Matière (CCQM) a key comparison, CCQM K55.c, was coordinated by Bureau International des Poids et Mesures (BIPM) in 2012. Twenty National Measurement Institutes or Designated and BIPM participated. Participants were required to assign mass fraction valine present as main component comparison sample for CCQM-K55.c. The samples prepared from analytical grade L-valine purchased commercial supplier...
[The authors studied the life table demography and population growth of Daphnia laevis using green alga iChlorella vulgaris cyanobacterium Microcystis aeruginosa (offered in colonial form) under two food concentrations (1 × 106 3 cells ml1). The experimental design consisted types food, algae, each with three replicates. was same for both study growth. variables derived were: age specific survivorship, age-specific reproduction, average lifespan, expectancy, gross reproductive rate, net...
The study of the structure and dynamics assemblages benthic organisms has gained interest in recent decades because it can account for influence anthropogenic activities coastal zone be incorporated into management conservation plans.The region Zihuatanejo, Mexico, had an accelerated unplanned urban development, negatively affecting communities.However, studies on algal assemblages, as well some predominant physical factors this are scarce.The objective research was to carry out a...
Non-catalytic wet air oxidation removes pharmaceuticals efficiently from hospital wastewater in low chemical oxygen demand conditions.
The increased demand for oil and gas places a burden on lands set aside natural resource conservation. Oil development alters the environment locally much broader spatial scale depending intensity extent of mineral extraction. current increase in exploration production United States prompted an update number pipelines wells associated with National Wildlife Refuge System (NWRS) lands. We obtained geospatial data location within close to boundaries NWRS (units) acquired as fee simple (i.e....
Wyoming is one of a few states that allow the discharge produced water from oil fields into surface waters for beneficial use by livestock and wildlife. Oil field discharges create wetlands provide habitat aquatic migratory birds other Wetlands surveyed in 1996 to 1999 showed inefficient oil-water separation contributed some receiving water. Over 62% sites had inadequate measures exclude wildlife, particularly birds, entering skim pits used separate The risk can be reduced significantly...
