“…In contrast, less tolerant taxa of Hemiptera, Odonata and Ephemeroptera were found upstream sites and decreasing downstream. These groups are very sensitive to change in nutrients, and use of pesticides and detergent [40,75,76]. Moreover, Hemiptera are adversely affected by inputs of soap and other surfactants [77].…”

Coupled change in land and water use due to increased farming intensity is a main factor affecting water quality and quantity, ecological functions and biodiversity globally. Prolonging growing seasons and increasing productivity in wetlands through irrigation have been targeted for increasing food security, particularly in developing countries. Nevertheless, irrigation and drainage have often been associated with degradation of water quality through increased agrochemical and fertiliser runoff and leaching at local scales. In this study, we investigated water quality in streams used for irrigation in a wetland area in Kilombero Valley, Tanzania. We measured physical-chemical water parameters and collected macroinvertebrates with different sensitivity to water quality across several small irrigation schemes covering various conditions. Turbidity, temperature, nitrate-N, and ammonium-N were significantly higher at sampling sites downstream of irrigation compared to upstream. Macroinvertebrate diversity, richness and average score per taxa (ASPT) were higher in general in sampling sites upstream of irrigation, with more sensitive macroinvertebrates decreasing in abundance downstream. There was a positive correlation between physical-chemical parameters and macroinvertebrate indices across the sites. We demonstrate that macroinvertebrate indices can be used as a quick assessment of water quality in response to irrigation schemes in small-scale farming systems of Tanzania. This in turn can allow us to track changes affecting wetland ecosystem function and biodiversity at higher trophic levels and across larger scales, thereby providing useful early warnings to help avoid widespread degradation under widespread agricultural intensification.Water 2019, 11, 671 2 of 22 extent and magnitude of impacts of anthropogenic activity at small scales to support management decisions and avoid compounded impacts at larger scales.Usually, the main source of agricultural irrigation water in wet landscape environments comes from surface water. Because of spatial variation of water chemistry in wetlands, streams and rivers, assessment and monitoring programs are necessary to provide robust insights into the quality and quantity of surface water supplies [11][12][13]. Increased use of chemicals and excess draining of wetlands for agriculture and the associated irrigation can have impacts not only on aquatic ecosystem, but also on human health. Fertilisers and agrochemicals impact physical-chemical characteristics of surface water and biota at different spatial scales [7,14]. Excess nitrate-N in drinking water, for example, impacts young livestock, pregnant women and infants on a local scale [15]. Ammonia and phosphorous in excess cause unpleasant colour, taste and odour of water [6]. At larger scales, leaching of excess nutrients can cause overproduction, algal accumulation and decrease dissolved oxygen in aquatic and wetland environments [16,17]. When pollution goes beyond the self-purifying ability of wetland ecosystems, death of aqu...

“…In this plantation, as seen in Table 1, species equitability (E) was 0.77, with a Margalef (α) richness index of 2.02 and a Shannon-Wiener (H) index of 2.18. A previous study by Rocha et al (2011c) in the municipality of Cuiabá with unchanged remnant Cerrado vegetation, observed that annual equitability (E) was 0.72, Margalef (α) diversity was 3.54, and Shannon-Wiener (H) index was 2.33. Their equitability value is similar to that of this study, but with higher values of diversity.…”

Bark beetles (Curculionidae: Scolytinae) are wood borers with the potential to cause significant damage in forest plantations. Studies of this group are more common in plantations of Eucalyptus, and Pinus, but the increase of planting with other forest species, such as Brazil nut and rubber trees, indicates the need for monitoring of Scolytinae in these additional forest areas. Thus, the objective of this work was to evaluate an assemblage and the main species of bark beetles in a mixed plantation of Brazil nut trees (Bertholletia excelsa Bonpl.) and rubber trees (Hevea brasiliensis (Willd. ex A.Juss.) Müll.Arg.) in Southern Amazonia. Twelve ethanol traps were used and collections were carried out biweekly for one year. The collections were evaluated descriptively way with entomofaunistic analysis, and population fluctuation and its dispersion were determined. A total of 2,738 individuals were collected, with a total of 17 species distributed in nine genera, of which Cryptocarenus Eggers 1937 and Xyleborus Eichoff 1864 showed the greatest representation. Cryptocarenus diadematus Eggers, Cryptocarenus heveae (Hagedorni), Cryptocarenus seriatus Eggers, Xyleborus affinis Eichhoff, and Xyleborus spinulosus Blandford were categorized as dominant, very abundant, very frequent, and constant. The assemblage of Scolytinae in the Brazil nut tree and rubber tree mixed plantation had a greater abundance in the rainy season, with the highest averages and population peaks. The species with the greatest representation also presented a greater number of individuals in the rainy season with aggregate dispersion.

“…Segundo esses mesmos autores, esse rápido crescimento teve um preço elevado e custou grande parte do capital natural existente, com consequente incremento e intensificação do desmatamento. Esses fatores interferem no ambiente natural e podem comprometer a qualidade da água para a flora e fauna (PRIMO et al, 2011).…”

“…A ordem Coleoptera representa o agrupamento mais rico em número de espécie de todo o reino Animalia, com mais de 385.000 espécies descritas até o momento (SLIPINSKI et al 2011), com os mais variados hábitos alimentares. Entre os insetos xilófagos, isto é, os que se alimentam de madeira, destacam-se os da família Cerambycidae, vulgarmente conhecidos como brocas, coleobrocas, serradores e serra-paus (PIRES et al, 2011).…”

A Classe Insecta representa 80% do Reino Animal e a ordem Coleoptera é a mais diversa em número de espécies, com os mais variados hábitos alimentares. Entre os insetos xilófagos, destacam-se os da Família Cerambycidae e poucos trabalhos relatam a presença de Lamiinae na região amazônica. Desta forma, este trabalho objetivou contribuir para o conhecimento da fauna de Lamiinae da região norte do estado de Mato Grosso. Os insetos foram coletados nos anos de 2008 a 2010, em área florestal, no período noturno, das 18: 00 as 06: 00 h., com armadilha luminosa, em duas áreas: nos municípios de Claudia (11º34'54.0"S; 55º17'15.6" W) e Sinop (11º 87' 20.9" S 55º 47' 48.6" W). No laboratório de Entomologia da Universidade Federal do Mato Grosso (UFMT), Câmpus de Sinop, os insetos foram triados, montados e separados para identificação das espécies. A presente contribuição enumerou 20 espécies de Lamiinae para o estado de Mato Grosso, distribuídos em 11 tribos e 18 gêneros, com quatro novas ocorrências para o estado e oito para a região norte do estado. Grosso e contribui para o conhecimento da riqueza e da distribuição de algumas espécies de Ceramcycidae, os quais constituem bons indicadores de diferentes compartimentos do sistema.Palavras-chave: Amazônia meridional; besouros; Insecta; inventário. CONTRIBUTION TO THE KNOWLEDGE OF LAMIINAE (COLEOPTERA: CERAMBYCIDAE) IN THE STATE OF MATO GROSSO, BRAZIL ABSTRACT: The Class Insecta, represents 80% of the Animal Kingdom and order Coleoptera is the most diverse, concerning the number of species, with the most varied eating habits. Among the xylophagous insects stand out from the family Cerambycidae and few studies have reported the presence of Lamiinae in the Amazon region. Thus, this study aimed to contribute to the knowledge of the fauna of Lamiinae from the northern state of Mato Grosso. The insects were collected in the years 2008-2010, in forest area, at night, from 18:00 to 06:00 h, with light traps in two areas: Municipalities Claudia (11º34'54.0"S; 55º17'15.6" W) and Sinop (11º87' 20.9" S 55º47' 48.6" W). In entomology laboratory of Universidade Federal de Mato Grosso (UFMT), Campus of Sinop, the insects were sorted, mounted, and separated to identification to species level. The present contribution listed 20 species of Lamiinae for the state of Mato Grosso, distributed in 11 tribes and 18 genera, with four new occurrences for the state and eight for the northern region of the state and contributes to the knowledge of the richness and distribution of some species of Ceramcycidae, which are good indicators of different compartments of the system.Keywords: beetles; Insect; inventory; Southern Amazon.
