Entomofauna associada às sementes de canela-guaicá [Ocotea puberula (Reich.) Ne...
Fleck, Marciane DannielaForest species may have their seeds damaged by granivorous insects, especially in the larval stage. The larvae feeding on the embryo and the reserve of the seeds sometimes prevent germination. Thus, studies related to the entomofauna associated with fruits and seeds, besides reporting the occurrence of these insects and their natural enemies, also indicate their potential risk of pest. In this context, the obje...

Fleck, Marciane Danniela; Costa, Ervandil Corrêa da; Araújo, Maristela Machado; Schoeninger, Karine; Machado, Leonardo Mortari; Silva, Jéssica Maus daForest species can have their seeds damaged by granivorous insects, especially by those in their larval stage. In this context, this study aims to report the occurrence of Amblycerus species in Cordia trichotoma seeds, to describe their main damage to seeds and effects on germination, as well as their associated hymenopteran parasitoids. Therefore, seven trees were selected in the municipality of Taquaruçu do S...
First record of Caliothrips phaseoli (Hood, 1912) (Thysanoptera: Thripidae) in ...
Boscardin, Jardel; Gomez de Oliveira, Gisele; Corrêa Costa, Ervandil; Carpenedo Aimi, Suelen; Fleck, Marciane Danniela; Machado Araujo, MaristelaThis study aimed to register the occurrence of phyllophagous insects attacking seedlings of Apuleia leiocarpa (Vogel) J. F. Macbr. (grapia), a native species to Brazil, which is on the red list of endangered native flora in Rio Grande do Sul State. In February 2012, adults of the pest Caliothrips phaseoli were identified causing damage to the leaves of 168 two-year-old grápia seedlings (mean stem diameter = 2.3...

These effects on natural resources may cause changes in diversity and composition of various groups of animals, including butterflies. Among several factors responsible for t...
Dynamics of use and land cover in the Rio Pardo valley, Rio Grande do Sul
Schroder, Thomas; Pereira, Rudiney Soares; Zimmermann, Anna Paula Lora; Redin, Cristina Gouvêa; Fleck, Marciane Danniela; Machado, Leonardo MortariThe aims of this study were to evaluate rates of deforestation and forest regeneration in the time span between 1990 and 2014, furthermore to estimate land cover and use by the year of 2018 in the Rio Pardo Valley region. Landsat images were used for land cover and use classification and Dinamica EGO software was used to provide real and estimated transitions among land cover and use classes. Forested area incr...
