Critical Thermal maximum (CTmax) is often used to characterize the upper thermal limits of organisms and represents a key trait for evaluating fitness ectotherms. The lack standardization in CTmax assays has, however, introduced methodological problems its measurement, which can lead questionable estimates species' limits. Focusing on ants, are model research ecology, we aim obtain reliable ramping rate that will yield most rigorous measures species.

Abstract The skin is a barrier between the internal and external environment of an organism. Depending on species, it participates in multiple functions. organ that holds body together, covers protects it, provides communication with its environment.

Climate change is affecting biodiversity and ecosystem function worldwide, the lowland tropics are of special concern because organisms living in this region experience temperatures that close to their upper thermal limits. However, it remains unclear how whether tropical species will be able cope with predicted pace climate warming.
