Temperature per se may explain Bergmann's rule in ectotherms (Atkinson & Sibly 1997, Blanckenhorn & Demont 2004), but not its converse, except when temperature operates as an indirect selective factor on body size by limiting nymphal growth and development (Masaki 1967).
Arboviruses have been reported to affect ectotherms, and in some cases ectotherms are thought to serve as a reservoir (1-4).

Indeed, this value likely underestimates the divergence time if a general trend for slower substitution rates in many fishes and other ectotherms (Avise et al.
Growth rates of ectotherms can be profoundly influenced by environmental conditions, especially temperature (Hartnoll 1982, Atkinson, 1994, vanderHave and deJong, 1996, Arendt, 2011).
As ectotherms butterflies are particularly thermally sensitive and so I will then assess the role of bacteria in host thermal tolerance and adaptation.
In most ectotherms, r reaches its maximum value at a greater temperature than for [R.
Thermal properties of retreat sites and perching sites are important, particularly for ectotherms, because of the effect of temperature on physiology (Huey, 1991).
Bergmann's Rule assumes an increase in body size with increasing latitudes/altitudes and was originally defined for endotherms, though later observed in many vertebrate and invertebrate ectotherms (Blackburn et al.
It is also well established that metabolism and growth are increased at higher ambient temperatures in ectotherms (Schmidt-Nielsen, 1990).
