TLDR
The biological account and phylogenetic results provide an opportunity for identifying some general trends and major innovations in the evolutionary history of Cassidinae.Abstract:
A parsimony analysis was undertaken to test subfamily and tribal group concepts of Cassidinae (ca. 2000 genera, ca. 6000 species). An integrated account of their biology was synthesized from the primary literature. A detailed morphological study of adults, using Hemisphaerota palmarum Boheman as a model, formed the basis for evaluating characters previously utilized and for defining novel characters. The data matrix comprised 210 characters (from adults and immature stages, ecology and behavior), 6 outgroups, and 98 ingroup exemplar species (representing 94 genera and 39 of the 43 recognized cassidine tribes). Results support the monophyly of Cassidinae and place it as sister to Galerucinae. The classical Hispinae s.str. is paraphyletic whereas the classical Cassidinae s.str. is monophyletic if some Imatidiine genera are included. Four tribes—Aproidini, Delocraniini, Hemisphaerotini, and Notosacanthini—are well supported by many autapomorphies. Multiple genera were sampled to test the monophyly o...read more

TL;DR: It is conceptualized that there are five ways in which a sexually dimorphic trait, apart from the primary sex traits, can be fixed: sexual selection, fecundity selection, parental role division, differential niche occupation between the sexes, and interference competition.

Conflict, Convergent Evolution, and the Relative Importance of Immature and Adult Characters in Endopterygote Phylogenetics
Rudolf Meier,Gwynne S. Lim +1 more
TL;DR: It is argued that DNA sequence-based matching of immature and adult stages will greatly help with the study of endopterygote immatures and facilitate the assembly of combined character matrices with data from all life-history stages.

Insect-damaged fossil leaves record food web response to ancient climate change and extinction.
TL;DR: Recent work on the time interval from the latest Cretaceous through the middle Eocene is emphasized, including two significant events that affected life: the end-Cretaceous mass extinction and its ensuing recovery; and globally warming temperatures across the Paleocene-Eocene boundary.

TL;DR: The high‐level classification of Chrysomelidae (leaf beetles) currently recognizes 12 or 13 well‐established subfamilies, but the phylogenetic relationships among them remain ambiguous, and full mitochondrial genomes were newly generated for 27 taxa and combined with existing GenBank data to provide a dataset of 108 mitochondrial genomes covering all subfam families.

TL;DR: The obligate partnership between tortoise leaf beetles and their pectinolytic Stammera symbionts is investigated to detail how changes to the bacterium's streamlined metabolic range can shape the digestive physiology and ecological opportunity of its herbivorous host.

Toward Defining the Course of Evolution: Minimum Change for a Specific Tree Topology
TL;DR: A method is presented that is asserted to provide all hypothetical ancestral character states that are consistent with describing the descent of the present-day character states in a minimum number of changes of state using a predetermined phylogenetic relationship among the taxa represented.

Organization of a Plant-Arthropod Association in Simple and Diverse Habitats: The Fauna of Collards (Brassica Oleracea)
TL;DR: The results suggest a new proposition, the resource concentration hypothesis, which states that herbivores are more likely to find and remain on hosts that are growing in dense or nearly pure stands; that the most specialized species frequently attain higher relative densities in simple environments; and that biomass tends to become concentrated in a few species, causing a decrease in the diversity of herbsivores in pure stands.

Branch support and tree stability
TL;DR: In this paper, the authors quantified the extra length needed to lose a branch in the consensus of near-most parsimonious trees based on the original data, as opposed to the data perturbation used in the bootstrap procedure.
