Temperature, demography, and ectotherm fitness.
Temperature has profound effects on ectotherms such as plants, invertebrates, and lower vertebrates (Hochachka and Somero 1984; Cossins and Bowler 1987). The impact of temperature is often depicted graphically as a “thermal performance curve,” which plots performance as a function of body temperature (Huey and Stevenson 1979). Typically, performance increases gradually with temperature up to so...
متن کاملambient temperature and confers heat resistance on ectotherm development
Effects of temperature on biological processes are complex. Diffusion is less affected than the diverse enzymatic reactions that have distinct individual temperature profiles. Hence thermal fluctuations pose a formidable challenge to ectothermic organisms in which body temperature is largely dictated by the ambient temperature. How cells in ectotherms cope with the myriad disruptive effects of ...
متن کاملDemography and the Coronavirus Pandemic
Abstract. One of the most urgent policy issues related to the COVID-19 pandemic in Europe concerns the extent and ways in which demographics have determined different patterns of mortality between groups and regions, and whether and how the pandemic and its economic consequences will affect population dynamics in the future. Post-pandemic policy evaluations on the spread of COVID-19 and the im...
متن کاملThe effects of elevated temperature on the sexual traits, immunology and survivorship of a tropical ectotherm.
In 2007, the Intergovernmental Panel on Climate Change projected an average global air temperature increase of 1.1-6.4°C by the end of the 21st century. Although the tropics are predicted to experience less extreme temperature increases than regions of higher latitude, tropical ectotherms live close to their thermal limits, and are thus particularly vulnerable to increases in temperature. In th...
متن کاملBeyond temperature coupling: Effects of temperature on ectotherm signaling and mate choice and the implications for communication in multispecies assemblages
Many organisms share communication channels, generating complex signaling environments that increase the risk of signal interference. Variation in abiotic conditions, such as temperature, may further exacerbate signal interference, particularly in ectotherms. We tested the effects of temperature on the pulse rate of male signals in a community of Oecanthus tree crickets, and for one focal speci...
