Abstract Habitat choice is fundamental for an animal foraging, defense, and reproduction.Ogre-faced spiders are known for their unusual morphology, natural history, and rarity.They are sit-and-wait predators that build net-like webs that are manipulated by spiders and thrown at their prey.Hunting behavior includes selecting microhabitats for web co
Enrichment of endothelial cell arachidonate by lipid transfer from high density lipoproteins: relationship to prostaglandin I2 synthesis.
We have previously shown that plasma high density lipoproteins (HDL) stimulate release of prostacyclin, measured as its stable metabolite, 6-keto-PGF1 alpha, by cultured porcine aortic endothelial cells.The present experiments were designed to elucidate the contribution of HDL lipids to endothelial cellular phospholipid pools and to prostacyclin sy
Formation of sects in a religious market
This paper is an extension of the recent work by the authors non-metal-chastity where a simplifying assumption of no costs of entry to the religious market was set.In the present paper, the religious market is regulated in the sense that a sect in order to establish itself in a market has to bear costs of entry.In the case of one official denominat
Critical political ecology and the seductions of posthumanism
"Posthumanist" theories have become increasingly popular among scholars in political ecology and other fields in the human sciences.The hope is that they will improve our grasp of relations between humans and various nonhumans and, in the process, offer the means to recompose the "social" and the "natural" domains.In this paper, I assess the merits
