Extended maternal care and offspring interactions in the subsocial Australian crab spider, Xysticus bimaculatus
The recent discovery of independently evolved subsociality in the thomisid Xysticus bimaculatus provides new potential for comparative studies to expand the limited understanding of group cohesion beyond the offspring’s potential independence and despite socially exploitative behaviour.

The mating system of the African cichlid fish Oreochromis mossambicus resembles that of other lekking animals; males defend mating territories where the spawning pits they dig are sites only for mating and oviposition and are not used for rearing offspring.
Intergenerational effects of inbreeding in Nicrophorus vespilloides: offspring suffer fitness costs when either they or their parents are inbred
The results of two experiments on the burying beetle Nicrophorus vespilloides suggest that intergenerational effects of inbreeding can have substantial fitness costs to offspring, and that future studies need to incorporate such costs to obtain accurate estimates of in breeding depression.
CHAPTER 1 What is parental care ?
The evolutionary causes of the observed diversity in the form, level, and duration of parental care are understood, as well as the extent to which it is provided by the male, the female, or both parents.
Post‐hatching parental care masks the effects of egg size on offspring fitness: a removal experiment on burying beetles
A parental removal experiment on the burying beetle Nicrophorus vespilloides is reported in which it is found that the parent's presence or absence had a strong main effect on larval body mass, whereas there was no detectable effect of egg size.
Parental care in Salamandrina perspicillata (Amphibia, Salamandridae): egg defence against caddisfly larvae
This work reports an egg-guarding behaviour in the Italian endemic, Salaman- drina perspicillata (a semi-terrestrial species with aquatic oviposition), against caddisfly larvae (Halesus ap- penninus).
Does environmental variability explain male parental care in a burying beetle
The load-lightening hypothesis, which holds that biparental care benefits future reproduction by lowering the costs of reproduction, is tested, and evidence of reproductive restraint associated with the higher temperature treatment in delayed egg-laying and increased feeding during second broods is found.
Temporal patterns, benefits, and defensive behaviors associated with male parental care in the glassfrog Centrolene savagei
Low rates of natural mortality suggest that male care for eggs is likely adaptive in this species of glassfrog, and preliminary results suggest that caring males have a higher tolerance toward threatening stimuli before fleeing than did solitary males.
Unconventional Care: Offspring Abandonment and Filial Cannibalism Can Function as Forms of Parental Care
Parental care is a key life-history trait that increases offspring fitness. When one thinks of parental care, nurturing behaviors such as guarding, provisioning, and grooming typically come to mind.
