“…Quantitative PCR approaches revealed that imidacloprid treatments during the adult stage are expressed as changes in immuneresponse, detoxification, and oxidation-reduction response in both workers and queens. In addition, transcriptomic approaches suggested that phototransduction, behavior, and somatic muscle development also were affected. …”

“…The distribution of supergene haplotypes in F. francoeuri differs from that of related species Formica selysi in that colonies with multiple queens contain almost exclusively workers that are heterozygous for alternative supergene haplotypes. …”

“…Moreover, we use the local indicators of spatial association technique to map regions of spatially correlated high multi-hazard risk in the NYC boroughs of The Bronx and parts of Brooklyn and Queens. These high risk locations account for nearly a quarter of the city's population, with households earning less than half than those in the lowest risk zones.…”

“…The number of bumblebees present during winter (October 2007 to March 2008) and the main plants they visited were also recorded during transect walks. Queens and workers were observed throughout the winter, suggesting a second generation of bee colonies active during the winter months. …”

“…In Acromyrmex Mayr (Hymenoptera: Formicidae) leaf-cutting ants, individual colonies maintain either a single or a few strains of Pseudonocardia, and the symbiont is primarily vertically transmitted between generations by colony-founding queens. A recent report found that Acromyrmex workers are able to differentiate between their native Pseudonocardia strain and non-native strains isolated from sympatric or allopatric Acromyrmex species, and show preference for their native strain. …”

Additionally, abdomens had the greatest endoreduplication of all body parts regardless of caste or size. …”

One significant aspect of the resulting design is that it encourages students to see ethical issues in systemic terms rather than from an individual perspective, with issues emerging from a conflict between different groups with different vested interests. …”
