1. Diet of benthivorous fish and prey availability in streams of the Pirapó River basin-PR
Resumo Objetivo O objetivo deste estudo foi avaliar a dieta de sete espécies de peixes que consomem predominantemente macroinvertebrados bentônicos, e a disponibilidade desses organismos no ambiente. Foi analisada a ocorrência de segregação trófica entre as espécies de peixes e a correlação entre a abundância de macroinvertebrados na dieta e no am

2. Dragonflies and damselflies (Insecta: Odonata) from a Cerrado area at Triângulo Mineiro, Minas Gerais, Brazil
Resumo: Odonata é considerada a segunda ordem de insetos com maior número de espécies de insetos aquáticos. Sua riqueza global é estimada em cerca de 6.000 espécies descritas. A odonatofauna encontrada no Brasil representa cerca de 14% da riqueza mundial, no entanto, o conhecimento sobre a distribuição de libélulas brasileiras ainda é incipiente. E

3. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

4. The invasive white ginger lily ( Hedichium coronarium ) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir
ABSTRACT The invasive white ginger lily (Hedichium coronarium - J. Köenig, 1783) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir. Invasive plants are believed to shift the trait composition of aquatic insects dwelling in banks of lentic ecosystems. In this study, we analyzed the relationship between the p

5. Association of Anagrus amazonensis Triapitsyn, Querino & Feitosa (Hymenoptera, Mymaridae) with aquatic insects in upland streams and floodplain lakes in central Amazonia, Brazil
ABSTRACT Anagrus amazonensis Triapitsyn, Querino & Feitosa (Hymenoptera, Mymaridae) is a parasitoid that uses aquatic insect eggs as a host for the development of its immature stages. The objectives of this study are to record the interaction between A. amazonensis and its hosts and the aquatic plants used by these hosts to lay their eggs. Field work was con

6. Effect of Bacillus sphaericus Neide on Anopheles (Diptera: Culicidae) and associated insect fauna in fish ponds in the Amazon
ABSTRACTWe analyzed the effects of Bacillus sphaericus on Anopheles larvae and on the associated insect fauna in fish farming ponds. Five breeding sites in the peri-urban area of the city of Manaus, AM, Brazil, were studied. Seven samples were collected from each breeding site and B. sphaericus was applied and reapplied after 15 days. The samples were made a

7. Effects of forest conversion on the assemblages' structure of aquatic insects in subtropical regions
The effects of forest conversion to agricultural land uses on assemblages of aquatic insects were analyzed in subtropical streams. Organisms and environmental variables were collected in six low-order streams: three streams located in a forested area, and three in areas converted to agricultural land uses. We expected that the aquatic insects' assemblage att

8. Autoecology of Dryadosaura nordestina (Squamata: Gymnophthalmidae) from Atlantic forest fragments in Northeastern Brazil
Life history parameters such as diet, reproduction, and sexual dimorphism are crucial to understand ecological and evolutionary forces shaping species traits. Nevertheless, such information is scant in the literature for most Neotropical squamates. Gymnophthalmidae contains over 242 species in 46 genera and includes small-size, mostly terrestrial species, al

9. Study of the mayfly order Ephemeroptera (Insecta) in Brazil: a scienciometric review
Study of the mayfly order Ephemeroptera (Insecta) in Brazil: a scienciometric review. Despite an increase in the number of studies in recent years of the aquatic insect order Ephemeroptera (the mayflies) much still remains to be learnt. In order to identify the current state of knowledge of this group in Brazil, we performed a scienciometric analysis with th

10. Fenologia de Cornops aquaticum (Bruner) (Orthoptera: Acrididae) em Eichhornia azurea (Pontederiaceae) no norte do Pantanal de Mato Grosso
Cornops aquaticum (Bruner) has Eichhornia crassipes, E. azurea, Pontederia cordata and P. lanceolata (Pontederiaceae) as the known host plants. This grasshopper species is cited as a possible agent of biological control for native aquatic macrophytes E. azurea and E. crassipes. This study, carried out from March, 2006 to February, 2007, aimed to evaluate the

11. The influence of habitat integrity and physical-chemical water variables on the structure of aquatic and semi-aquatic Heteroptera
This work aimed to assess the effect of certain physical-chemical variables and the Habitat Integrity Index (HII) have on an aquatic and semi-aquatic heteropteran community. We collected in five streams (from 1st to 4th order) that differed in habitat integrity, in order to test 1) whether heteropteran richness decreases with the Habitat Integrity Index; and

12. Neutral Theory could explain diversity of aquatic insects in streams? / A Teoria Neutra pode explicar a diversidade de insetos aquáticos em riachos?
The generality of Unified Neutral Theory of Biodiversity and Biogeography was evaluated across its support for diversity structure of Odonata adults and predators, shredders and collectors insect guilds in streams. The evaluation of Neutral Theory was done in two levels of theorys hierarchical structure. One evaluation in the level of yours assumptions, the
