Different hypotheses attempt to explain how different stages of organisms with complex life
cycles respond to environmental changes. Most studies have focused at the among-species …

We proposed two improvements to the Logan model of temperature-dependent
development. We first eliminated a redundant parameter (modification 1) then incorporated …

Given the current rapid climate change, understanding the mechanisms underlying heat
tolerance and its plasticity is an important goal of global change biology. Soil fauna …

Case studies on development-time data collected at constant and varying temperatures in a
number of insects have been analyzed in a comparative manner to investigate the effects of …

Operative and standard operative temperatures, Te and Tes) are pseudo-temperatures
denning “environmental temperature.” They have numerous applications, including …

The study of thermoregulation in endotherms has contributed much to the emergence of the
concept of control theory in biology. By the same token, the study of temperature adjustment …

Publisher Summary This chapter describes the basic mechanisms in longtime thermal
adaptation. Unlike technical regulatory systems, the biological thermoregulatory system …

Models of thermal adaptation assume that warm-adapted and cold-adapted organisms can
achieve the same fitness, yet recent comparative studies suggest that warm-adapted …

Thermal constants. lower development threshold (LDT) and sum of effective temperatures
(SET) were recalculated from literature data for 335 insect species. Included were only …
