Galling insects are bioindicators of environmental quality in a Conservation Unit
TLDR
The diversity of galls at Parque Estadual Serra Verde reflects an area with high levels of stress but with moderate botanical diversity, which can support the status of conservation of an area as an urban park, once inventories are presented.Abstract:
Galls are well distributed across the World and among plant families. Their diversity can support the status of conservation of an area as an urban park, once inventories are presented. These inventories also help to understand the morphological patterns of the galls, based on their most common shape, color, host botanical families, inducers and galled organs. This study is about an inventory of galls at Parque Estadual Serra Verde, Brazil. This conservation unit is an urban park strongly anthropized in a transition area of Cerrado and Mata Atlântica. Galls from four different trails were observed, and collected monthly during one year. The terminology morphospecies was used to distinguish the galls because the identification of the inducers were not always possible. Seventy five morphospecies of galls belonging to 43 host plant species of 24 botanical families were observed. Mostly of the galls was induced by Diptera:Cecidomyiidae, in Fabaceae and Myrtaceae. The most common traits were the globoid shape and green color. The leaves were the most frequent galled organ and followed by the stems. All these tendencies had been already observed in other inventories. Comparing current results with other studies at similar areas, we can assume that the Parque Estadual Serra Verde is very important for conservation. Urban green areas are subject to high disturbance and degradation but also increase the quality of life for the population inhabiting the areas nearby. The diversity of galls at Parque Estadual Serra Verde reflects an area with high levels of stress but with moderate botanical diversity. These features make this protected area an important site for the continuous conservation and regeneration, and highlight the environmental value of Parque Estadual Serra Verde.read more

TL;DR: The animal-induced galls have a striking anatomical diversity, concerning several patterns, which were reunited herein, and culminates in extant gall structural diversity.

Insects as an Indicator for Environmental Pollution
TL;DR: In this paper, the main goal of research on bioindicators is to identify species that would reliably indicate disturbances in the environment, and the main focus is to find species that are reliable indicators of environmental pollution.

Totipotent nutritive cells and indeterminate growth in galls of Ditylenchus gallaeformans (Nematoda) on reproductive apices of Miconia
TL;DR: Such long-distance effects indicate that D. gallaeformans is a peculiar colonial parasite, which may compensate the damages of gall inducing mechanisms by favoring, at least partially, its host plant fitness.

Questioning the environmental stress hypothesis for gall diversity of restinga vegetation on dunes
TL;DR: Despite the environmental stresses, the xeric features of the dunes of the ASP, and the high local plant diversity, the diversity of galling herbivores were low and the environmental effect seems to be neutral, either for the host plants or for the generation of gall morphotypes.
