Responses of riffle beetle assemblages to deforestation in a semi-deciduous Atlantic Forest remnant Anais da ABC (AABC)
BRAUN,BRUNA M.; BERTASO,TIAGO R.N.; PIRES,MATEUS M.; SPIES,MARCIA R.; KOTZIAN,CARLA B..
Abstract Deforestation affects freshwater assemblages since aquatic organisms are dependent on the structure of the riparian vegetation. To investigate the responses of riffle beetles (Elmidae) to deforestation, this study assessed the structure of riffle beetle assemblages found in streams running through a large and well-preserved semi-deciduous Atlantic Forest remnant in Southern Brazil and in nearby deforested areas. Additionally, the effects of different substrate types (litter and stone) on the assemblages were assessed. Riffle beetle assemblages showed a remarkably distinct structure between forested and deforested areas. Lower abundance occurred in deforested streams. Indicator genera of forested streams were detected (e.g.,Macrelmis and...

Flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae) in the Upper Paraná River floodplain, Brazil Anais da ABC (AABC)
Mendonça,Luciana B.; Anjos,Luiz dos.
We investigated flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae), a common ornithophilous shrub found in the riparian forest understory in the Upper Paraná River floodplain, Brazil. Flowers are distylous and the style-stamen dimorphism is accompanied by other intermorph dimorphisms in corolla length, anther length, and stigma lobe length and form. We did not observe strict reciprocity in the positioning of stigma and anthers between floral morphs. Flowering occurred during the rainy season, October to December. Nectar standing crop per flowerwas relatively constant throughout the day, which apparently resulted in hummingbirds visiting the plant throughout the day. Energetic content of the nectar in each flower...

Environmental diagnosis of metals in streams near sugarcane cultivation areas: current and historical analysis in the central region of the State of São Paulo Anais da ABC (AABC)
CORBI,JULIANO J.; COSTA,CAMILA G.; GORNI,GUILHERME R.; COLOMBO,VANESSA; RIOS,LEONARDO.
Abstract In Brazil, innumerable regions of native landcover have been removed and replaced by agricultural cultivation, especially of sugarcane. In this culture, the application of fertilizers containing metals has caused impacts on the water resources causing contamination of stream sediments and occasioning bioaccumulation of metals in aquatic invertebrates. In the year of 2006, an environmental diagnosis of metals in sediments of streams located near sugarcane cultivation areas and in streams located in preserved areas, was published. That study pointed to high concentrations of metals in stream sediments in agricultural areas. These streams have been monitored over the last 10 years conducting analyses of metals and monitoring possible changes in land...

Fabaceae of the Rio São Francisco River sub-basin, Nova Marilândia, Mato Grosso, Brazil Biota Neotropica
Silva,Rosilene Rodrigues; Souza-Lima,Eliane Semidei de.
The watershed of the São Francisco River is a large complex of headwaters of the Paraguay River, the main river of the Pantanal Matogrossense. Considering that Fabaceae are pointed out as the main family in floristic composition of various Brazilian biomes, however in some regions of Brazil is still little known upon the taxa, particularly in the Northern part of the Central-West, this study aimed to present a list of taxa occurring in the sub-basin of the São Francisco River, municipality of Nova Marilândia, State of Mato Grosso. For the taxa we give information on habit, vegetation, data on geographic distribution, potential use, successional strategy and dispersal syndrome, to subsidize habitat restoration projects. We recorded a total of 44 taxa,...

Allelopathic evidence in exotic guava (Psidium guajava L.) BABT
Chapla,Tatiani Elisa; Campos,João Batista.
The allelopathic activity of the leaf aqueous extract of guava (Psidium guajava L.) on seed germination and root growth in lettuce (Lactuca sativa L.) was studied in an experiment consisting of four replicates with 10 seeds each and extract concentrations of 5, 10, and 20%. Guava allelopathic activity occurred during the germination and growth of lettuce roots at 20% extract concentration, as shown by ANOVA. This result suggested the allelopathic potential of the species. Therefore, the success of P. guajava in invading environments could be partially due to allelopathy. Further studies using other plant parts and field experiments should be conducted.

Arboreous vegetation of an alluvial riparian forest and their soil relations: Porto Rico island, Paraná river, Brazil BABT
Campos,João Batista; Souza,Maria Conceição de.
The dynamics of alluvial deposits in floodplains forms islands and sandbanks. Deposits frequently accumulate at the river margins and on islands with consequent side growths. One of these sandbanks which started to form in 1952 annexed an area of 12.4ha to the Porto Rico island (53º15’W and 22º45’S). At present a forest fragment of approximately 2.0 ha exists in this place. The structural analysis of arboreous vegetation of this fragment showed a floristic gradient related to the physical and chemical variations of the substratum. High density of pioneer species associated to the absence of recruitment of new individuals of these and other successional categories indicated that the forest was impaired in its succession process. This fact could be...

Dynamics of allochthonous organic matter in a tropical Brazilian headstream BABT
Gonçalves Júnior,José Francisco; França,Juliana Silva; Callisto,Marcos.
The species composition of the riparian vegetation and the seasonal contribution of input and storage of fine and coarse particulate organic matter were assessed in a 3rd order stretch. Fourteen tree species in the riparian zone were identified, with 3 species contributing with 68% of total litter input: Miconia chartacea Triana (43%), Miconia cyathanthera Triana (16%) and Erythroxylum pelletarianum St. Hil (9%). The allochthonous input of coarse particulate organic matter (CPOM) was composed mainly by leaves (over 50%). Species composition and the contribution of each plant species biomass for vertical, lateral and soil inputs and benthic stocks varied along the study period. The maximum values found in September, November and December coincided with the...

Relationship between sugar cane cultivation and stream macroinvertebrate communities BABT
Corbi,Juliano José; Trivinho-Strixino,Susana.
The aim of this work was to study the influence of the sugar cane cultivation on the macroinvertebrate communities of 11 streams under different land uses. Analysis of the sediment (organic matter contents and metals) and water complemented the study. Ninety six macroinvertebrates taxa were identified, of which 54 were Chironomidae and 42 of other aquatic macroinvertebrates. The streams located in the areas of sugar cane culture and pasture presented low taxa and a great participation of Chironomidae (78% of the total). In contrast, the streams located in the areas with riparian vegetation presented a rich aquatic fauna with less participation of Chironomidae (60% of the total).

Allochthonous matter input in two different stretches of a headstream (Itatinga, São Paulo, Brazil) BABT
Afonso,Ana Adelina de O.; Henry,Raoul; Rodella,Rita C.S.Maimoni.
In two streches of the Itaúna stream, one in a gallery forest and the other in an herbaceous vegetation zone, litter matter input (sorted by leaves, ligneous and reproductive components) were measured during a year. In the gallery forest stretch, the direct input and lateral transport attained 713 g.m-2.year-1 and 421 g.m-1. year-1, respectively. In contrast, the herbaceous vegetation stretch showed a direct litter input and lateral transport of only 86 g.m-2.year-1 and 124 g.m-1. year-1, respectively. The empoverishment of riparian vegetation had a significant effect on the decrease of allochthonous input to stream mainly by direct input. Peaks of direct input into Itaúna stream occurred during late dry season and in the early wet season. They were...

Distribution of benthic communities in relation to the environmental integrity of subtropical streams Ecología austral
Pujarra,Samaila; Klosinski Lourenço,Danielle; de Almeida Gurski,Fernanda; dos Santos,Ana P. A; Moretto,Yara.
The benthic macroinvertebrate community structure is directly related to environmental factors such as water characteristics, habitat availability and substrate heterogeneity. This study had the purpose of characterizing the benthic macroinvertebrate community and compare its attributes in streams located inside (preserved area) and outside (altered area) the Iguaçu National Park, in the west of Parana, Brazil, in two season (dry and rainy). Three replicates per site were obtained through the Surber collector in four microhabitats (litter pool, litter riffle, substrate pool and substrate riffle). There was significant discrimination in the benthic fauna composition among the study areas (Wilks=0.091; F272,746= 2.249; P<0.0001). The taxa Corbiculidae,...
