The obligate pollination mutualism between yuccas (Agavaceae) and yucca moths
(Lepidoptera, Prodoxidae), in which the adult moth pollinates yucca flowers and her progeny …

Along with increases in empirical information about interspecific mutualisms have come both
new and refined questions about them. These questions have spurred diversification in the …

This book offers a concise but comprehensive introduction to desert ecology and adopts a
strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis …

Hermaphroditic individuals can produce both selfed and outcrossed progeny, termed mixed
mating. General theory predicts that mixed‐mating populations should evolve quickly toward …

Cooperation invites cheating, and nowhere is this more apparent than when different
species cooperate, known as mutualism. In almost all mutualisms studied, specialist …

Many tree crops experience sub-optimal yields and low fruit quality due to inadequate
pollination, low fruit set, and poor crop nutrition. Boron (B) is a critical crop nutrient for fruit …

Host shifts followed by specialization can result in sympatric genetic differentiation, and may
have fuelled the diversification of phytophagous insects. This study examines a recent …

Summary 1 A mutualism is a mutually beneficial interaction between individuals of two
species. Here we show that the degree of benefit resulting from an interaction depends on …

Seed size plays a pivotal role in plant life history. It is a result of the interrelationship of a
wide array of proximate and ultimate factors—many of these acting in conflicting directions …

We used phylogenetic and ecological information to study the evolution of host‐plant
specialization and colour polymorphism in the genus Timema, which comprises 14 species …
