The nematode, Mehdinema alii, occurs in the alimentary canal of the decorated cricket Gryllodes sigillatus. Adult nematodes occur primarily in the hindgut of mature male crickets, whereas juvenile nematodes are found in the genital chambers of mature male and female crickets. Here, we present experimental evidence for the venereal transmission of M. alii in G. sigillatus. Infectivity experiment...

The spider genus Enna O. Pickard-Cambridge, 1897 comprises 38 species, distributed from Mexico to Southern Brazil, and is the most diverse genus of Trechaleidae (Platnick, 2013). Enna was revised by Silva et al. (2008) and 13 further species were described by Silva & Lise (2009a, 2009b), Carico & Silva (2010), Silva & Lise (2011) and Silva et al. (2012). Silva & Lise (2010) and Silva et al. (20...

We investigate whether the first digit of an odometer reading is more salient to consumers than subsequent digits. We find that retail transaction prices and volumes of used vehicles drop discontinuously at 10,000-mile odometer thresholds, echoing effects found in the wholesale market by Lacetera, Pope and Sydnor (2012). Our results reveal that retail consumers devote limited attention to evalu...

Motivated by the Beauville–Voisin conjecture about Chow rings of powers of K3 surfaces, we consider a similar conjecture for Chow rings of powers of EPW sextics. We prove part of this conjecture for the very special EPW sextic studied by Donten–Bury et alii. We also prove some other results concerning the Chow groups of this very special EPW sextic, and of certain related hyperkähler fourfolds....

We thank Ramos-Silva et al. (1) for their thoughtful comments on our work recently published in PNAS (2). We agree that careful cleaning of biomineral samples is indeed necessary for appropriate proteomic analysis. However, we respectfully disagree with their interpretation of our cleaning methods and our decision to include certain proteins in our final list of 36 potential biomineralization p...
