Distribution and Natural History of the Workerless Inquiline Ant Pogonomyrmex Anergismus Cole (Hymenoptera: Formicidae)

Seven colonies of the rare inquiline Pogonomyrmex anergismus Cole were located in New Mexico, two in Hidalgo County, and five in Grant County; P. rugosus was the host for each. Mating flights follow late summer rains. Males mated with colony-mates, mostly inside the nest, and then returned to the nest, Pogonomyrmex anergismus may parasitize host nests over multiple years, with...

Selection against Aerial Dispersal in Ants: Two Non-Flying Queen Phenotypes in Pogonomyrmex laticeps

The South American seed-harvester ant Pogonomyrmex laticeps has dimorphic queens: ergatoid (permanently wingless) and brachypterous (short, non-functional wings). Surveys in western Argentina indicated that colonies near Chilecito, La Rioja Province, produced only ergatoid queens, while those near Punta Balasto, Catamarca Province (263 km away), produced only brachypterous queens...

The Old Ladies of the Seed Harvester ant Pogonomyrmex Rugosus: Foraging Performed by Two Groups of Workers

We examined temporal polyethism in Pogonomyrmex rugosus, predicting a pattern of decreasing age from foragers to nest maintenance workers to individuals that were recruited to harvest a temporary food source. Nest maintenance workers were younger than foragers, as indicated by their heavier mass and lower mandibular wear. In contrast, recruited foragers were similar in mass to...

A procedure to statistically evaluate agreement of differential expression for cross-species genomics

Motivation: Animal models play a pivotal role in translation biomedical research. The scientific value of an animal model depends on how accurately it mimics the human disease. In principle, microarrays collect the necessary data to evaluate the transcriptomic fidelity of an animal model in terms of the similarity of expression with the human disease. However, statistical methods...

Assisted Fontan procedure: animal and in vitro models and computational fluid dynamics study☆☆☆

Fontan connection with intermittent compression by wrapped latissimus dorsi (LD) was tested in vivo, in vitro and by means of computational fluid dynamics (CFD). Experimental study: LD was conditioned in four pigs for three weeks before Fontan connection by valved conduit wrapped with LD. Mock circuit: Inflatable cuff wrapped around valved conduit provided intermittent external...
