Foraging by predatory ants: A review
Insect Science, EarlyView.This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Toxin diversity revealed by a transcriptomic study of Ornithoctonus huwena. [PDF]
PLoS ONE, 2014 Spider venom comprises a mixture of compounds with diverse biological activities, which are used to capture prey and defend against predators. The peptide components bind a broad range of cellular targets with high affinity and selectivity, and appear to

A new approach to the $SL_n$ spider [PDF]
arXiv, 2018 The $SL_n$ spider gives a diagrammatic way to encode the representation category of the quantum group $U_q(sl_n)$. The aim of this paper is to define a new spider that contains the $SL_n$ spider. The new spider is defined by generators and relations, according to fairly simple rules that start with combinatorial data coming from the root system of ...

Journal for Eighteenth-Century Studies, EarlyView.Abstract In mid‐eighteenth‐century Europe, anonymous authors produced parodic satires masquerading as earnest exemplars of the chronicle form. Couched in an antiquated, quasi‐biblical register, these mock chronicles drew flimsily fictional portraits of modern life.

Spiders can be recognized by counting their legs [PDF]
arXiv, 2014 Spiders are arthropods that can be distinguished from their closest relatives, the insects, by counting their legs. Spiders have 8, insects just 6. Spider graphs are a very restricted class of graphs that naturally appear in the context of cograph editing. The vertex set of a spider (or its complement) is naturally partitioned into a clique (the body),

Ballooning Spiders: The Case for Electrostatic Flight [PDF]
arXiv, 2013 We consider general aspects of the physics underlying the flight of Gossamer spiders, also known as ballooning spiders. We show that existing observations and the physics of spider silk in the presence of the Earth's static atmospheric electric field indicate a potentially important role for electrostatic forces in the flight of Gossamer spiders.

Swamped: On Depression and Vision
American Anthropologist, EarlyView.ABSTRACT “Swamped” cracks open my experience of depression by exploring how a specific place—a swamp—acted on me to bring social and emotional injuries, but also modes of seeing that ultimately moved me out of the depression, to the fore. In writing from this specific place, I build on moments in which something—a desire for beauty, the luminosity of ...
