Here we review and extend the equal fitness paradigm (EFP) as an important step in
developing and testing a synthetic theory of ecology and evolution based on energy and …

Trade-offs and constraints are inherent to life, and studies of these phenomena play a
central role in both organismal and evolutionary biology. Trade-offs can be defined …

The evolution of investment per offspring (I) is often viewed through the lens of the classic
theory, in which variation among individuals in a population is not expected. A substantial …

The term 'life-history theory'is a familiar label in several disciplines. Life-history theory has its
roots in evolutionary models of the fitness consequences of allocating energy to …

The essential introduction to population ecology—now expanded and fully updated Ecology
is capturing the popular imagination like never before, with issues such as climate change …

Energy storage in arthropods has important implications for survival and reproduction. The
lipid content of 276 species of adult arthropods with wet mass in the range 0.2–6.13 g is …

Identification of mechanisms that promote variation in life-history traits is critical to
understand the evolution of divergent reproductive strategies. Here we compiled a large life …

Aim We provide a new quantitative analysis of lizard reproductive ecology. Comparative
studies of lizard reproduction to date have usually considered life‐history components …

Context: As a result of increases in life expectancy and decreases in fertility, the proportion
of the population entering later life has increased dramatically in recent decades. When …

The male genitalia of arthropods consistently show negative static allometry (the genitalia of
small males of a species are disproportionally large, and those of large males are …
