Changing paradigms in insect social evolution: insights from halictine and allodapine bees.
Until the 1980s theories of social insect evolution drew strongly on halictine and allodapine bees. However, that early work suffered from a lack of sound phylogenetic inference and detailedExpand

Long-Term Changes in Survival Rates of Lesser Snow Geese
Survival rates of adult and juvenile Lesser Snow Geese (Anser caerulescens caerulescens) were estimated based on hunter recoveries from over 80 000 geese banded between 1970 and 1988 at La PerouseExpand

The socioecology of body size variation in the primitively eusocial sweat bee, Halictus ligatus (Hymenoptera: Halictidae)
Patterns of demographic and social variation exhibited by the sweat bee Halictus ligatus, reveal that the expression of eusocial colony organization is associated with local environmental conditions,Expand

Evidence for geographic variation in colony social organization in an obligately social sweat bee, Lasioglossum malachurum Kirby (Hymenoptera; Halictidae)
The expression of altruism and colony eusociality are both a matter of degree in social sweat bees. Even in obligately social species, variation in these traits may be observed across a species'Expand

A novel social polymorphism in a primitively eusocial bee
Halictine sweat bees (Hymenoptera, Halictidae) are model organisms for the evolution of altruism, reproductive castes, and eusocial colony organization. Halictine social behavior is not onlyExpand

Survival rates of Lesser Snow Geese (Chen caerulescens caerulescens) were ex- amined based on recoveries and recaptures of about 350,000 geese banded at breeding colonies in northern Canada, atExpand

Annual and Social Variation in Foraging Effort of the Obligately Eusocial Sweat Bee, Halictus ligatus (Hymenoptera: Halictidae)
Abstract Previous studies of the obligately eusocial sweat bee Halictus ligatus Say, at a nesting aggregation in Victoria, southern Ontario, Canada, showed how changes in local environmentalExpand

Trophic aspects of caste determination in Halictus ligatus, a primitively eusocial sweat bee
Caste determination in primitively eusocial sweat bees is thought to be due to an interacting suite of factors, including size of the larval provision mass, time of year, and social context of theExpand

It's good to be queen: classically eusocial colony structure and low worker fitness in an obligately social sweat bee
Lasioglossum malachurum, a bee species common across much of Europe, is obligately eusocial across its range but exhibits clear geographic variation in demography and social behaviour. This variationExpand
