The predatory behavior of ants: an impressive panoply of morphological adaptations
Insect Science, EarlyView.This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Multi-modal courtship in the peacock spider, Maratus volans (O.P.-Cambridge, 1874). [PDF]
PLoS ONE, 2011 The peacock spider, Maratus volans, has one of the most elaborate courtship displays in arthropods. Using regular and high-speed video segments captured in the lab, we provide detailed descriptions of complete male courtship dances.

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope
Integrative Zoology, EarlyView.The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

Polymorphism in an ant mimicking jumping spider [PDF]
Journal of Arachnology, 2010 Abstract Myrmarachne bakeri Banks 1930 is a polymorphic, generalized ant-mimicking jumping spider. In this study, variation in its polymorphic characters was observed and described. Myrmarachne bakeri varies in color, glossiness and patterns; and differs from other polymorphic ant-like spiders because it becomes polymorphic before adulthood ...

A Note on the Depth-from-Defocus Mechanism of Jumping Spiders [PDF]
Biomimetics, 2017 Jumping spiders are capable of estimating the distance to their prey relying only on the information from one of their main eyes. Recently, it has been shown that jumping spiders perform this estimation based on image defocus cues. In order to gain insight into the mechanisms involved in this blur-to-distance mapping as performed by the spider and to ...

Integrative Zoology, EarlyView.This study investigates the potential adaptive advantages of female‐specific UV‐induced fluorescence in male mate‐choice and predation risk, as fitness costs, using two species of ornate jumping spiders Phintella vittata and Ph. bifurcilinea. Our findings provide empirical evidence of a trade‐off: While fluorescence enhances male mate preference, it ...

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 ...
