Variation in endocrine pathways can be a major mechanism underlying life-history evolution. Yet it is unclear whether this insight, derived primarily from solitary species, explains the origins of complex life-history traits in highly social taxa. Th

In the honey bee (Apis mellifera), young workers usually perform tasks in the nest while older workers forage in the field. The behavioral shift from nest-task to foraging activity is accompanied by physiological and sensory changes so that foragers

Research on aging shows that regulatory pathways of fertility and senescence are closely interlinked. However, evolutionary theories on social species propose that lifelong care for offspring can shape the course of senescence beyond the restricted c

The honey bee originated in tropical Africa and later dispersed to northern Europe. It has been suggested that a higher hemolymph storage capacity for the glycolipoprotein vitellogenin evolved in temperate regions, and that the trait constitutes an a

A striking example of plasticity in life span is seen in social insects such as ants and bees, where different castes may display distinct ageing patterns. In particular, the honeybee offers an intriguing illustration of environmental control on agei

Vitellogenin is a female-specific glucolipoprotein yolk precursor produced by all oviparous animals. Vitellogenin expression is under hormonal control, and the protein is generally synthesized directly before yolk deposition. In the honeybee ( Apis m

Antithrombin, a major coagulation inhibitor in mammals, has for the first time been cDNA cloned from a fish species. The predicted mature liver antithrombin of Atlantic salmon (Salmo salar) consists of 430 amino acids and shows about 67% sequence ide

Antithrombin from bony fish ( Teleostei ), represented by an ancient salmonid, Atlantic salmon ( Salmo salar L.), and a more evolved species from the same family, rainbow trout ( Oncorhynchus mykiss Walbaum), functions in vitro as does its human coun

Plasma factor X (FX) was severely depleted in Atlantic salmon and rainbow trout after 18 days of oral warfarin administration; this response was further reflected in prolonged prothrombin time. Thus, both species require vitamin K for the maintenance
