“…(e.g. Garamzegi et al 2012;Sol et al 2018;Mayhew 2018) suites of questions concerning behavioural variation in salmonids that, in our opinion, deserves to be investigated further. Working with these suites of questions will not only increase the knowledge about salmonid behaviour, but will also advance the fields of ethology and behavioural ecology in general.…”

“…Extraordinary diversity of insects remains little used in phylogenetic comparative studies (Mayhew 2018), perhaps largely due to scarcity of comparable data. This also applies to studies on longevity.…”

A comparative study on insect longevity: tropical moths do not differ from their temperate relatives

If the evolutionary determinants of longevity were mainly extrinsic, related species from different habitats should systematically differ in individual lifespans. Comparative studies of insects can signi cantly contribute to understanding the evolution of lifespan, as the trait can feasibly be measured in a high number of species. We recorded adult longevities for 110 species of geometrid moths from a tropical community. Comparative analyses based on an original phylogenetic reconstruction were applied to reveal the correlates of species-speci c values of lifespan. Larger moth species were found to live longer, and females tended to have shorter lifespans than males. Average adult lifespans in tropical geometrids, and the relationships of lifespan with other variables, were found to be highly similar to those reported for their temperate region relatives. The among-region similarity leads to the conclusion of the dominance of intrinsic (physiological) determinants of longevity over the extrinsic (ecological) ones: the contrasting environments of tropical and temperate forests have not produced detectable differences in moth longevities.

“…Both broad and narrow phylogenetically informed comparisons can be used to investigate the origins of social behavior. The numerous independent origins of parental care within the insects provide an opportunity to generate hypotheses of evolutionary transitions using phylogenetic contrasts (Gilbert & Manica, 2015;Mayhew, 2018). Specific transitions can be examined in clades that have closely related species that differ markedly in the extent of parental care (Field et al, 2020).…”

Comparative experimental study of species can provide insight into behavioral transitions in evolution. The insects offer many such examples for the analysis of parental care. We examined three distantly related species of Nicrophorus and two non-Nicrophorus silphid beetles for their ability to conceal odors from a carcass that cue competitors that attempt to usurp the resource. We predicted that species with well-developed parental care would exhibit a heightened ability to conceal a resource from competitors, even when differences in burying behavior and direct defense were experimentally eliminated. Carcasses were provided to male-female pairs in the laboratory for 3 days and then experimentally buried in the field, without parents, to assess discovery by Nicrophorus and vertebrate scavengers. The burying beetles Ni. orbicollis, Ni. sayi and Ni. pustulatus were far more successful in hiding a prepared resource (>76%) from free-flying Nicrophorus than the less parental Ptomascopus morio or Necrophila americana (<25%). Carcasses provided to P. morio and Ne. americana were also more likely to be discovered by Nicrophorus than non-prepared control carcasses, suggesting that microbially derived odor cues available to competitors were increased by non-Nicrophorus interaction with carcasses. In the absence of burial, carcass preparation had no effect on vertebrate scavenging. We hypothesize that the evolution of burying and carcass modification to conceal a discovered resource from diverse competitors, more so than control of microbial decay, was a critical step in the evolutionary transition to monopolization of a small carcass, nesting and extended parental care in the Silphidae.
