Today we hit a milestone few labs pass with the appearance of our 500th published paper. For a complete list of publications by M.S. Engel refer to the links provided on our Publications page.
25 April 2013:
The long-awaited Treatise on the Isoptera of the World was published today in seven volumes. The work is the first to treat the entire living and fossil fauna of termites, with a consideration of the history of isopterology, the comparative morphology of termites, a review of their phylogeny and evolutionary history, summary of pest species, and revised suprageneric classification. It also includes a fully annotated and revised taxonomic catalog for the termites, living and extinct.

20 February 2013:
The discovery of male and female Strashilidae, including individuals in copula and with their fully-developed dipteran wings, reveal conclusively that this is a family of nematoceran flies related to Nymphomyiidae and that, like nymphomyiids, were amphibious and shed their wings. The male hind legs, as is common among different insect lineages, were modified for grasping the female. Utterly unfounded notions of strashilids as ectoparasites are based on fanciful hypotheses devoid of evidence or rational reasoning. These results were released today in Nature (HERE).

OLDER NEWS ITEMS
2 August 2012: The discovery of a complete insect from the Late Devonian of Belgium, one of only a small handful of definite records of the entire class from this period, was reported today in Nature (HERE). Garrouste, R., G. Clement, P. Nel, M.S. Engel, P. Grandcolas, C. D'Haese, L. Lagebro, J. Denayer, P. Gueriau, P. Lafaite, S. Olive, C. Prestianni, & A. Nel. 2012. A complete insect from the Late Devonian period. Nature 488(7409): 82-85.
1 March 2012: The discovery of giant fleas from the Jurassic and Cretaceous highlight the earliest evidence of the lineage of these familiar ectoparasites. The discovery was reported today in Nature (HERE). Huang, D., M.S. Engel, C. Cai, H. Wu, & A. Nel. 2012. Diverse transitional giant fleas from the Mesozoic era of China. Nature 483(7388): 201-204. Listen (here) to the interview from "Quirks & Qarks" on CBC Radio. This discovery was highlighted in the top 100 scientific discoveries of 2012 by Discover Magazine (January-February 2013 issue).
6 February 2012: The discovery of a katydid from the Jurassic with its stridulatory structures exceptionally well preserved was reported in PNAS (HERE). The specimen permitted a biomechanical and bioacoustical reconstruction of its call, revealing that the species produced a pure-tone (musical) call. Gu, J.-J., F. Montealegre-Z., D. Robert, M.S. Engel, G.-X. Qiao, & D. Ren. 2012. Wing stridulation in a Jurassic katydid (Insecta, Orthoptera) produced low-pitched musical calls to attract females. Proceedings of the National Academy of Sciences, USA 109(10): 3868-3873.
21 November 2011: Contributions Celebrating Kumar Krishna (edited by M.S. Engel). Check it out HERE. A 332 page volume of contributions focusing on the systematics and biology of Isoptera, as well as papers on Embiodea, Orthoptera, Hymenoptera, and Diptera, were published today. These papers are brought together by friends, colleagues, and admirers of Prof. Dr. Kumar Krishna, in recognition of his multiplicity of accomplishments in termite systematics and biology as well as the enormous influence his work, generosity, and kindness has had on all of us.
24 September 2011: Advances in the Systematics of Fossil and Modern Insects: Honouring Alexandr Rasnitsyn (edited by D.E. Shcherbakov, M.S. Engel, & M.J. Sharkey). Check it out HERE. A 542 page volume of contributions to the systematics of living and fossil insects was released on 24 September, the 75th birthday of the great hymenopteran systematist Alexandr P. Rasnitsyn (and 40th birthday of M.S. Engel). Contributions to many orders of insects are included, but particularly a diversity of lineages among the Hymenoptera.
4 April 2011: The discovery of the oldest full-body impression, trace fossil of a flying insect was reported on today in PNAS and in the 5 April 2011 Science Times of the New York Times (HERE). The trace fossil is from the Late Carboniferous of Massachusetts. Knecht, R.J., M.S. Engel, & J.S. Benner. 2011. Late Carboniferous paleoichnology reveals the oldest full-body impression of a flying insect. Proceedings of the National Academy of Sciences, U.S.A. 108(16): 6515-6519.
23 March 2011: An isotope analysis of modern resin exuded from mountain pine beetle (Dendroctonus ponderosae) attacks reveals 13C enrichment signals that track the progression of infestation and instances of recovery. These same signals are found in ancient resins (amber) and provide insight concerning the genesis of amber deposits. Read more HERE: McKellar, R.C., A.P. Wolfe, K. Muehlenbachs, R. Tappert, M.S. Engel, T. Cheng, & G.A. Sanchez-Azofeifa. 2011. Insect outbreaks produce distinctive carbon isotope signatures in defensive resins and fossiliferous ambers.
