The Influence Of Low Humidity, Pseudacteon Flies, And Competition By Solenopsis Xyloni On Solenopsis Invicta, R A. Ramirez, D C. Thompson, M D. Remmenga Aug 2006

The Influence Of Low Humidity, Pseudacteon Flies, And Competition By Solenopsis Xyloni On Solenopsis Invicta, R A. Ramirez, D C. Thompson, M D. Remmenga

Biology Faculty Publications

Red imported fire ant, Solenopsis invicta Buren, is a serious pest in the southeastern United States. It has caused economic losses in agricultural products, stings can cause anaphylactic shock, and it has reduced biodiversity. S. invicta has displaced native ant species throughout its range, presumably by competitive exclusion. In 1998, S. invicta populations were confirmed in southern New Mexico, resulting in a quarantine of Doña Ana County. Although large populations of the native southern fire ant, S. xyloniMcCook, are common in the Mesilla Valley, only two small populations of S. invicta have been found since the initial quarantine. It is ...


Queen Weights Of Polygyne Solenopsis Invicta And S. Xyloni Suggest Reduced Competitive Ability, R A. Ramirez, D C. Thompson Mar 2006

Queen Weights Of Polygyne Solenopsis Invicta And S. Xyloni Suggest Reduced Competitive Ability, R A. Ramirez, D C. Thompson

Biology Faculty Publications

Solenopsis invicta Buren populations were confirmed in southern New Mexico, resulting in a quarantine of Doña Ana County in 1998; however, Solenopsis xyloni McCook remains the dominant fire ant. This study compared the queen weights and egg production of polygyne colonies of both species. There was no difference in live weights of the major worker caste; however, queens were very different in weight. In this study, S. invicta queens weighed almost twice as much as S. xyloni (S. invicta = 11.32 ± 0.25mg vs. S. xyloni = 6.40 ± 0.30mg) and produced over 50% as many eggs as S. xyloni ...

Endothelial Cell Cortactin Coordinates Icam-1 Clustering And Actin Cytoskeleton Remodeling During Polymorphonuclear Leukocyte Adhesion And Transmigration, Jennifer Kowalski Jan 2006

Endothelial Cell Cortactin Coordinates Icam-1 Clustering And Actin Cytoskeleton Remodeling During Polymorphonuclear Leukocyte Adhesion And Transmigration, Jennifer Kowalski

Scholarship and Professional Work - LAS

Endothelial cell ICAM-1 interacts with leukocyte beta2 integrins to mediate adhesion and transmit outside-in signals that facilitate leukocyte transmigration. ICAM-1 redistribution and clustering appear necessary for leukocyte transmigration, but the mechanisms controlling ICAM-1 redistribution and clustering have not been identified. We recently reported that Src kinase phosphorylation of endothelial cortactin regulates polymorphonuclear cell (PMN) transmigration. In this study, we tested the hypotheses that the Src family kinase-cortactin pathway mediates association of ICAM-1 with the actin cytoskeleton and that this association is required for ICAM-1 clustering and leukocyte transmigration. Cross-linking ICAM-1 induced cytoskeletal remodeling and a decrease in ICAM-1 lateral mobility ...
