The renaissance of interest in sexual selection during the last decades has fuelled an
extraordinary increase of scientific papers on the subject in spiders. Research has focused …

Dwarf males are often found in species with sedentary females, where they typically cohabit
in varying degrees of intimacy. This is short of true parasitism because, in return for room …

Why do males and females frequently differ so markedly in body size and morphology? Sex,
Size, and Gender Roles is the first book to investigate the genetic, developmental, and …

One cannot help being struck with wonder at the vivid pink of 10,000 flamingos rising from
Lake Nakuru or the glowing red gorget of a ruby-throated hummingbird feeding outside the …

Spiders are the preeminent silk craftsmen among arthropods and are best known for
producing aerial orb webs that snare flying insects. Orb web spiders are ubiquitous …

Instances of sexual size dimorphism (SSD) provide the context for rigorous tests of biological
rules of size evolution, such as Cope's rule (phyletic size increase), Rensch's rule (allometric …

Extreme sexual body size dimorphism (SSD), in which males are only a small fraction of the
size of the females, occurs only in a few, mostly marine, taxonomic groups. Spiders are the …

We present a new phylogeny of the spider family Araneidae based on five genes (28S, 18S,
COI, H3 and 16S) for 158 taxa, identified and mainly sequenced by us. This includes 25 …

The Pantropical spider clade Nephilidae is famous for its extreme sexual size dimorphism,
for constructing the largest orb‐webs known, and for unusual sexual behaviors, which …

Sexual conflict theory predicts an antagonistic coevolution, with each sex evolving
adaptations and counter–adaptations to overcome a temporary dominance of the other sex …
