Male–female coevolution has taken different paths among closely related species, but our
understanding of the factors that govern its direction is limited. While it is clear that …

According to sexual selection theory, the sexes are faced with opposing evolutionary goals.
Male fitness benefits from access to females, whereas female fitness is constrained by food …

Crickets have been extensively studied in recent insect nutritional research, but it remains
largely unexplored how they balance the intake of multiple nutrients. Here, we used the …

When the likelihood of reproducing successfully is low, any prior investment in developing
oocytes may be wasted. One means of recouping this investment is oosorption–where ova …

Nutrition is one of the underlying factors necessary for the expression of life-histories and
fitness across the tree of life. In recent decades, the geometric framework (GF) has become a …

Dietary macronutrients regulate life span and aging, yet little is known about their
evolutionary effects. Here, we examine the evolutionary response of these traits in decorated …

In animal breeding programs, utilizing quantitative genetic designs such as the full-/half-
sibling design is fundamental. A full-/half-sibling design demands that mating can be …

Animals regulate their nutrient consumption to maximize the expression of fitness traits with
competing nutritional needs (“nutritional trade‐offs”). Nutritional trade‐offs have been …

Animals often regulate the intake and quantity of nutrients to maximise fitness through life‐
history traits such as lifespan, but we still lack a proper understanding of how specific …

The Geometric Analysis of the Effects of Dietary Macronutrients on Physiological, Behavioral
and Life History Traits in the Yellow Mealworm Beetle, Tenebrio molitor (Coleoptera …
