Common-intersection hypothesis of development rate lines of ectotherms within a taxon revisited

Developmental Database for Phenology Models: Related Insect and Mite Species Have Similar Thermal Requirements

“…Our results on the similarity of thermal requirements of related species conÞrm, by rigorous statistically tests, previous indications on the similarity of thermal requirements for related species (Jarošṍk et al 2002, Ikemoto 2003, Dixon et al 2005, Kiritani 2006, Bonato et al 2011. Because the taxonomical hierarchy was treated as a random effect, our inference on taxonomy can be applied to a wider population from which the species are derived, that is, to any species belonging to that genus, family, and order (Blackburn and Duncan 2001).…”

“…From evolutionary point of view, this Þnding may suggest that species developing from a common ancestor can radiate to new environments with different temperature conditions, forming a related species group with different LDTs and rates of development (Ikemoto 2003). The intrinsic optimum temperature thus could be used as an indicator for classifying phylogenetic relatedness (Ikemoto 2005), and there are also indications that it can be used for testing of developmental rate isomorphy (Bonato et al 2011). .…”

“…Later it was shown that rate isomorphy occurs in all ectotherm animals (Jarošṍk et al 2004), and different methods to tests for rate isomorphy were developed (Shi et al 2010, Bonato et al 2011. There are also indications that it might be applied to plants.…”

Temperature-dependent development in Chrysomela vigintipunctata (Coleoptera: Chrysomelidae), a stenothermal early-season breeder

“…However, this information is insufficient to realize how rapid the development in C. vigintipunctata is when compared to its congeners and other leaf beetles. Development time among genotypes, populations, or species should be compared at several temperatures simultaneously because the degree of temperaturedependence of development may vary, and a difference in development time found at a given temperature may not hold at other temperatures (Gupta and Lewontin, 1982;Bonato et al, 2011;Saska et al, 2014). Moreover, the developmental rate shows a linear relationship to temperature in the non-stressful thermal range, and this allows for estimating a theoretical lower temperature threshold (LTT) for development (Campbell et al, 1974).…”

Could the intrinsic rate of increase represent the fitness in terrestrial ectotherms?

“…The 95% confidence interval of the differences between the bootstrap replications of T F,d and the bootstrap replications of T F,g is [ À0.0361, 0.6413], including zero. Bonato et al (2011) suggested that the developmental rates for closely related species within a taxon might be constant at temperature T F . According to previous studies (see Shi et al, 2012, and references therein), for most insects and mites, T F is around 20 1C with a range of 15-25 1C.…”
