Termites (Isoptera) from the Jurassic/Cretaceous boundary: Evidence for the longevity of their earliest genera

open access: yesEuropean Journal of Entomology, 2014
The earliest termite of the extant genus Mastotermes, is herein recorded in the Jurassic/Cretaceous (J/K) transitional beds of Chernovskie Kopi in Transbaikalian Russia along with Santonitermes of an uncertain family. These records represent the earliest

An insect wing discovered in the Early Permian Taiyuan Formation (Shanxi Province, China) [PDF]

open access: yesFossil Record, 2019
The first discovery of an insect wing from the Taiyuan Formation, near Yangquan City, Shanxi Province, China, is described. The combination of its wing venation characters makes it difficult to assign it to any known major Paleozoic group. The comparison

Evolution of reproductive strategies in dictyopteran insects—clues from ovipositor morphology of extinct roachoids [PDF]

open access: yesActa Palaeontologica Polonica, 2018
Dictyoptera, which comprises cockroaches, termites and mantids, is a quite successful group of insects in evolutionary terms with a long fossil record—roachoid insects were already abundant 315 million years ago in the Carboniferous forests.

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

New aphid taxa from Obeshchayushchiy (north-eastern Russia) and their implications for the evolutionary stage of the group in the Late Cretaceous

open access: yesThe European Zoological Journal
In this paper, we complement and extend the list of aphid taxa from Obeshchayushchiy, described from the Late Cretaceous. A new endemic subfamily is established based on new materials: Promissaphidinae subfam. nov.

A review of the Carboniferous fossil insects from Scotland

open access: yes, 2010
The known fossil insects of Carboniferous age from Scotland are reviewed. Of the seven recorded, one record is highly dubious and rejected, and another is herein identified as a crustacean.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
