An overview of inventories of gall-inducing insects in Brazil: looking for patterns and identifying knowledge gaps Anais da ABC (AABC)
ARAÚJO,WALTER S. DE; FERNANDES,GERALDO W.; SANTOS,JEAN C..
We compiled published Brazilian gall-inducing insect inventories aiming to understand trends and biases in this field research and to investigate the factors that potentially explain the diversity of gall-inducing insects among different sampling sites. A total of 51 studies with gall-inducing insect inventories were compiled for Brazil, which sampled 151 sites in 88 municipalities, 13 states and five regions. The number of papers published on gall-inducing insects per year has increased over the last 30 years, being Cecidomyiidae (Diptera) the main galling taxon, Fabaceae the main host-plant family and Protium heptaphyllum (Burseraceae) the most important super-host species in these inventories. We found a great bias in the geographical distribution of...

Structural analysis of a fragmented area in Minas Gerais State, Brazil Anais da ABC (AABC)
SALOMÃO,NATÁLIA V.; MACHADO,EVANDRO L.M.; PEREIRA,RAFAELLA S.; FERNANDES,GERALDO W.; GONZAGA,ANNE P.D.; MUCIDA,DANIELLE P.; SILVA,LEOVANDES S. DA.
Abstract The theory of landscape ecology applied to the methods of spatial analysis helps to understand changes in the structure of forest remnants. In view of this theory, the objective of the present study was to analyze the structure of a fragmented area between the years 1979 and 2015 through calculation of landscape metrics for arboreal, shrubby and herbaceous vegetation classes. Vegetation classes were classified with visits to the field, interpretation of aerial photographs from 1979 and supervised classification of Landsat 8 from 2015. The metrics calculated for each class were area and total number of fragments, total edge and average connectivity among the fragments. The analysis of structure found that it changed negatively due to an increase in...
