The effect of fire on ant assemblages does not depend on habitat openness but does select for large, gracile predators

open access: yesEcosphere, 2021
Ecosystems can respond in a variety of ways to the same agent of disturbance. In some contexts, fire causes large and long‐lasting changes to ecological communities. In others, fire has a limited or short‐lived impact on assemblages of animals and plants.

Sex and Clonality in the Little Fire Ant [PDF]

open access: yesMolecular Biology and Evolution, 2007
Reproduction systems are controlling the creation of new genetic variants as well as how natural selection can operate on these variants. Therefore, they had historically been one of the main foci of evolutionary biology studies. The little fire ant, Wasmannia auropunctata, has been found to display an extraordinary reproduction system, in which both ...

Red Imported Fire Ants Reduce Invertebrate Abundance, Richness, and Diversity in Gopher Tortoise Burrows

open access: yesDiversity, 2020
Gopher Tortoise (Gopherus polyphemus) burrows support diverse commensal invertebrate communities that may be of special conservation interest. We investigated the impact of red imported fire ants (Solenopsis invicta) on the invertebrate burrow community ...

Appendix C. A repeated-measures ANOVA table for the effects of field, date, fire ants, aphids, date×fire ants, fire ants×aphids, and date×fire ants×aphids on the community of cotton arthropods during the 2001 field season.

open access: yes, 2016
A repeated-measures ANOVA table for the effects of field, date, fire ants, aphids, date×fire ants, fire ants×aphids, and date×fire ants×aphids on the community of cotton arthropods during the 2001 field ...

Repellent Effects of Five Plant Essential Oils on the Red Imported Fire Ant, Solenopsis invcita

open access: yesSociobiology, 2015
The aim of this experiment was to search for the essential oils which have repellent effects on red imported fire ants. Effect of five kinds of essential oils in four concentrations on fire ant workers was evaluated using a Y-tube olfactometer bioassay ...

Crazy ants vs. small and large fire ants.

open access: yes, 2013
A) The effect of fire ant worker size on the average number of fire ants fighting during each observation (out of a total of five fire ants). Small fire ants fought more often than large fire ants.

Anti‐Inflammatory and Neuroactive Effects of Polymer‐Coated Iron Oxide Nanoparticles Functionalized With Interleukin 4 for Spinal Cord Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
Polymer‐coated IONPs functionalized with IL‐4 display respective neuroactive and anti‐inflammatory actions on neural progenitor cells and macrophages/microglia in vitro. When examined chronically in a rat experimental model of spinal cord injury, rGO scaffolds carrying these nanosystems adequately integrate into the lesion, significantly reduce ...

Ant-fungal diversity in fire ants

open access: yes, 2020
This research is focused on the ant-fungal diversity found in Invasive Fire Ants. The project looked at the difference in both diversity and abundance of fungal morphospecies found within fire ants, the colony soil, and the control ...

Developmentally Guided Differentiation of Ventral Midbrain Dopaminergic Cells Validated in Proteopathy‐Based Parkinson's Disease Models

open access: yesAdvanced Science, EarlyView.
A developmentally guided protocol reproducibly specifies EN1‐positive ventral midbrain dopaminergic (vmDA) progenitors from human pluripotent stem cells and yields functional vmDA neurons. Optogenetic induction of α‐synuclein aggregation elicits selective degeneration of TH‐positive neurons in 2D cultures and 3D neurospheroids, while transplanted ...

Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

open access: yesAdvanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.
