Abstract Inadequate and unregulated disposal of agricultural commercial residues represents a significant challenge for the management environmental impacts. The inadequate this waste can lead to accumulation high concentrations heavy metals, including cadmium, chromium, lead, manganese, zinc, in soil. Many insects are excellent bioindicators contamination, although their capacity superficial bioaccumulation particles will depend on life cycle, structure body integument, behavioral patterns...
The present study was conducted in five different phytogeographic zones of the Brazilian state Maranhão, three which (the Amazon Forest, Cerrado, and Palm Groves) are more heterogeneous, whereas other two (Marshlands Mangroves) homogeneous. In each zone, nine sites were visited for collection necrophagous flies using bait traps 2010, 2011, 2012. calliphorid sarcophagid communities observed at site compared terms species richness, composition, abundance. heterogeneous had higher except case...
This study aimed at surveying the local calliphorid and sarcophagid species in Maranhão State (Brazil) to determine their distribution abundance, as well of exotic Chrysomya species. In total, 18,128 specimens were collected, distributed 7 genera 14 The Hemilucilia semidiaphana (Rondani, 1850) Paralucilia paraensis (Mello, 1969) new state records. albiceps (Wiedemann, 1819) Cochliomyia macellaria (F., 1775) most abundant species, together contributed more than 50% total blow fly abundance....
The level of association between dipterans the families Calliphoridae and Sarcophagidae habitats with different levels vegetation cover was analyzed at Porto Urucu in Coari, Amazonas, Brazil, aim identifying potential these taxa as bioindicators for assessment forest regeneration conservation. flies were collected 16 sample areas, 12 which clearings stages (C1—early regeneration; C2—moderate C3—advanced regeneration) 4 continuous (F). According to IndVal analysis, nine sarcophagid...
The Chapada das Mesas National Park is a federal reserve located in the State of Maranhão, an ecotonal region Brazilian Northeast Cerrado. Aiming to assess influence biogeographic patterns and support restoration actions for regions where information scarce, we analyzed floristic composition savanna forest Cerrado physiognomies, relationships with other areas investigated between Amazon, Caatinga Atlantic Forest biomes. A total 242 species 181 genera 64 families are recorded our study....
Este trabalho foi realizado na base de extração petrolífera, bacia do Rio Urucu, Coari, Amazonas, nos meses abril, junho e outubro 2007. Um total 16 áreas foram amostradas, 12 delas clareiras quatro florestas, sendo categorizadas em ambientes (clareiras pouco recuperadas, semi-recuperadas, bem recuperadas floresta preservada). 7.215 califorídeos capturados pertencentes a espécies uma única delas, Chloroprocta idioidea (Robineau-Desvoidy, 1830), representou 88,06% deste total. Os padrões...
A diversidade e abundância de dípteros califorídeos três ambientes (clareira artificial, clareira natural mata) Porto Urucu/AM foram avaliadas em coletas anuais realizadas 2004, 2005 2006. Ao longo destes anos coletados 2.121 exemplares pertencentes a 14 espécies. As espécies mais abundantes Chloroprocta idioidea (Robineau- Desvoidy), Eumesembrinella randa (Walker) Hemilucilia semidiaphana (Rondani). Os habitats matas clareiras naturais apresentaram maior quando comparados às artificiais,...
Diversity of Calliphoridae and Sarcophagidae (Diptera, Oestroidea) in continuous forest gaps at different stages regeneration the Urucu oilfield western Brazilian Amazonia. The diversity was studied river basin, Coari, state Amazonas, Brazil. flies were collected 16 sampling points, 12 (early _ C1, mid- C2 late successional C3) four MT. blowflies similar two less regenerated habitats (C1 C2), lower than that (C3) forests (MT). By contrast, flesh much higher all three types (C1, comparison...
Oxysarcodexia cocais sp. nov. from Brazil is described and illustrated based on male specimens collected in a babassu palm forest the state of Maranhão. The remarkable elongated surstylus (as long as cercus) U-shaped sternite 5 distinguishes new species other genus. In addition, nitida Soares & Mello-Patiu, 2010 recorded for first time Brazil, adunca Lopes, 1975 record Brazilian Amazon.
Field incubations have been pointed out as the more realistic method to provide estimates of nitrogen (N) mineralization. The aim this study is evaluate quality results obtained in a field incubation using an open reactor estimate net N mineralization and leaching. experiment was initiated with 24 reactors. At each date, reactors were destructed mineral soil adsorbed on exchange resins determined. Net leaching estimated 23.3 18.0 mg/kg, respectively. revealed acceptable repeatability,...
The cation–anion exchange resin membrane (CAERM) system is one of the most promising alternative methodologies for assessment soil phosphorus (P) availability. Nevertheless, CAERM method has a recommended period extraction (16 h) that limits its applicability. With aim to improve use in routine laboratory work, seven times were studied and compared repeatability biological accuracy, using 150 samples soils covering wide range properties. results showed dissimilar quantities extractable P,...
<title>Abstract</title> The various ecosystems of the Amazon biome play a vital role in maintenance biodiversity, as well providing important ecosystem services at local and global levels. Small-bodied generalists include number groups, such insects order Odonata. Given their sensitivity to environmental alterations, odonates are also valuable bioindicators quality. In this context, present study evaluated distribution diversity adult Legal Amazonia zone Brazilian state Maranhão, verify...
