Competition and opportunity shape the reproductive tactics of males in the ant Cardiocondyla obscurior. [PDF]

open access: yesPLoS ONE, 2011
Context-dependent adjustment of mating tactics can drastically increase the mating success of behaviourally flexible animals. We used the ant Cardiocondyla obscurior as a model system to study adaptive adjustment of male mating tactics.

Survey of Ants in Dry Forests of Southwestern Ecuador (Hymenoptera: Formicidae)

open access: yesSociobiology, 2016
Two dry forests of southwestern Ecuador separated 43 km from each other, one situated at 460 m above sea level and the other at 680 m, are surveyed for ants giving a total of 28 species collected manually and from pitfall traps. Eleven species are shared

Mating with stressed males increases the fitness of ant queens. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: According to sexual conflict theory, males can increase their own fitness by transferring substances during copulation that increase the short-term fecundity of their mating partners at the cost of the future life expectancy and re-mating ...

Evolutionary history, novel lineages and symbiont coevolution in the ant tribe Camponotini (Hymenoptera: Formicidae)

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 646-676, July 2025.
Phylogenomic data illuminate the evolutionary history of the ant tribe Camponotini and its obligate bacterial endosymbiont, Blochmannia, and suggest a Paleotropical Eocene origin of the association. We discover three novel lineages of camponotine ants, previously misidentified as members of the large cosmopolitan genus Camponotus.

New data on the ant fauna (Hymenoptera: Formicidae) of Azerbaijan [PDF]

open access: yesКавказский энтомологический бюллетень, 2019
Ants of Azerbaijan are relatively poorly known compared to other parts of the Caucasus area and Europe. To improve the knowledge of the ant fauna, we performed field sampling in 2017, including different habitats extending throughout the country.

Unrecognized Ant Megadiversity in the Australian Monsoonal Tropics: The Melophorus castaneus Heterick, Castalanelli & Shattuck Species Group (Hymenoptera: Formicidae)

open access: yesEntomological Research, Volume 55, Issue 4, April 2025.
ABSTRACT This paper continues the documentation of remarkable levels of undescribed ant diversity in the Australian monsoonal (seasonal) tropics. It considers the Melophorus castaneus Heterick, Castalanelli & Shattuck species group, as considered here consisting of four described species: M. castaneus, M. clypeatus Heterick, Castalanelli & Shattuck, M.

Ant queens increase their reproductive efforts after pathogen infection [PDF]

open access: yesRoyal Society Open Science, 2017
Infections with potentially lethal pathogens may negatively affect an individual's lifespan and decrease its reproductive value. The terminal investment hypothesis predicts that individuals faced with a reduced survival should invest more into ...
