Diversity, disturbance, and sustainable use of Neotropical forests: insects as indicators for conservation monitoring
TL;DR: In this paper, a short-cycle indicator group of non-economical insects, whose population levels and resources are readily measured, is evaluated as focal indicator taxa for rapid assessment of changes in Neotropical forest systems.
Journal ArticleDOI
Atlantic Forest Butterflies: Indicators for Landscape Conservation1
TL;DR: The Atlantic Forest region (wide sense) includes very complex tropical environments, increasingly threatened by extensive anthropogenic conversion (>90%). Ecologically specialized, short-generation insects (butterflies) are evaluated here as indicators for monitoring community richness, landscape integrity, and sustainable resource use in the region as discussed by the authors.
Journal ArticleDOI
Adult-obtained pyrrolizidine alkaloids defend ithomiine butterflies against a spider predator
TL;DR: It is shown here that the protection of ithomiines against this abundant predator is due to dehydropyrrolizidine alkaloid monoesters and their N-oxides, absent from Solanaceae but sequestered by these butterflies as adults from flowers and decomposing foliage and also important in the reproduction of the Ithomiinae11,14.
Phylogeny Of The Nymphalidae (lepidoptera).
TL;DR: A generic level phylogeny for the butterfly family Nymphalidae was produced by cladistic analysis of 234 characters from all life stages as mentioned in this paper, which supported the monophyly and relationships of most presently recognized subgroups, providing strong evidence for the presently accepted phylogenetic scheme.
Journal ArticleDOI
Phylogeny of the Nymphalidae (Lepidoptera).
TL;DR: This phylogeny includes the widest taxon coverage of any morphological study on Nymphalid butterflies to date, and supports the monophyly and relationships of most presently recognized subgroups, providing strong evidence for the presently accepted phylogenetic scheme.
