Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope
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.

New observations of frog and lizard predation by wandering and orb-weaver spiders in Costa Rica
Studies have suggested that predation by spiders may be an important force regulating life history in neotropical frogs and lizards, but detailed descriptions of predator-prey relationships are few.

Background Locomotor performance in ecologically relevant activities is often linked to individual fitness. Recent controversy over evolution of extreme sexual size dimorphism (SSD) in spiders centres on the relationship between size and locomotor ...

Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Beyond Manoeuvre Theory for European Defence
ABSTRACT This article contributes to the debate about European defence in the light of the Russo‐Ukraine war and growing doubts about US commitment to Europe. It argues that Europeans need to fundamentally relearn the ability to imagine military strategy from a European viewpoint.

Commerce, coalitions, and global value chains: Coordinated and collective lobbying on trade
Abstract Global value chains (GVCs) have connected firms in complex networks within and across national borders. However, political economy models often assume away production linkages and thus fail to explain pervasive and diverse trade coalitions cutting across industries and firms. I develop a GVC‐centered framework where production linkages through

Untangling the Tangle-Web: Web Construction Behavior of the Comb-Footed Spider Steatoda triangulosa and Comments on Phylogenetic Implications (Araneae: Theridiidae) [PDF]
Theridiidae typically construct a three-dimensional web often described as "irregular.” The web consists of a supporting structure and lines under tension termed gumfooted lines.

Abstract In recent years, Berlin has emerged as an epicenter of climate activism in Germany. There, a range of groups have mobilized in opposition to the role of the German state and the EU in accelerating the climate crisis. Many activists now see conventional political responses as exhausted and have turned to increasingly radical forms of civil ...
