Sociogenomics of Cooperation and Conflict during Colony Founding in the Fire Ant Solenopsis invicta

open access: yesPLoS Genetics, 2013
One of the fundamental questions in biology is how cooperative and altruistic behaviors evolved. The majority of studies seeking to identify the genes regulating these behaviors have been performed in systems where behavioral and physiological ...

Effects of post‐fire on seed germination and seedling recruitment of a generalist savanna woody species

open access: yesPlant Biology, EarlyView.
This study evaluated germination, recruitment, and early seedling growth of Vochysia tucanorum through a field experiment based on direct seed deposition into the soil under natural conditions, simulating post‐dispersal environments in burned and unburned areas.

Bringing Fire Back: How Prescribed Fires Shape Ant Communities in a Fire-Suppressed Neotropical Savanna

open access: yesDiversity
We evaluated the effects of different fire regimes on the ground-ant community from a savanna (Cerrado) reserve in southern Brazil, where a process of woody encroachment has been taking place. Ants are a dominant faunal group in tropical savannas.

The Effects of Temperature on the Foraging Activity of Red Imported Fire Ant Workers (Hymenoptera: Formicidae) in South China

open access: yes, 2014
In this study, we investigated the effects of temperature of the ambient air, ground surface, and the soil at 5-cm deep on the foraging activity of the workers of red imported fire ant, Solenopsis invicta Buren, in South China with the method of bait ...

Conceptualizing and contextualizing “large‐scale” and “scaling‐up” ecological restoration

open access: yesRestoration Ecology, EarlyView.
Current restoration efforts are lagging behind the extent and pace of environmental degradation. This emphasizes the need and urgency to scale up ecological restoration. This study sought to understand the context of “large‐scale” and “scaling‐up” ecological restoration, that is, what it means, entails, where, and how it is implemented by ...

Presence of the red imported fire ant at gopher tortoise nests

open access: yesWildlife Society Bulletin, 2016
Red imported fire ants (Solenopsis invicta; fire ants) are predators of turtle (Testudine) eggs and hatchlings, but little information is available indicating how and when fire ants detect turtle nests during incubation.

Trait‐based recovery of insect functional diversity following pine removal in a shrubland biodiversity hotspot

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...

Molecular structure and diversity of PBAN/Pyrokinin family peptides in ants

open access: yesFrontiers in Endocrinology, 2012
Neuropeptides are the largest group of insect hormones. They are produced in the central and peripheral nervous systems and affect insect development, reproduction, feeding and behavior. A variety of neuropeptide families have been identified in insects.
