Species with widespread distributions frequently show clines in body size across broad
geographic areas. These clines may be the result of “ecogeographical rules” that describe …

While greater species diversity exists at tropical latitudes for many groups, certain parasitoid
wasp families (ie Ichneumonidae) exhibit a peak in species diversity at mid-latitudes …

Population-level analyses of colony development have enhanced our understanding of the
origins and maintenance of eusocial behavior in insects (Jeanne & Davidson 1984 …

Many social insects exhibit morphologically distinct worker and queen castes that perform
different functions. These functional differences may generate unique selection regimes …

The production schedules of males and reproductive females by the foundress queens and
the ratios of parental investment in males and reproductive females (investment sex ratios) …

Recent studies report that reproductive and non-reproductive roles of individuals can be
associated with body size variation and/or physiological differences in many primitively …

We used a standard sampling protocol to measure elevational patterns of species richness
and abundance of eusocial paper wasps (Hymenoptera: Vespidae) in Costa Rica. The …

Spatial behaviour of colony members within a nest represents an essential aspect of colony
organization. However, little attention has been devoted to the study of this aspect in social …

Relatively little is known about the processes shaping population structure in cooperatively
breeding insect species, despite the long-hypothesized importance of population structure in …

The foraging behavior of social wasps may vary throughout the day in response to different
factors, including environmental variation and interspecific interactions. Body size is known …
