Late-life fitness gains and reproductive death in Cardiocondyla obscurior ants

eLife, 2022
A key hypothesis for the occurrence of senescence is the decrease in selection strength due to the decrease in the proportion of newborns from parents attaining an advanced age – the so-called selection shadow.

A map of brain neuropils and fiber systems in the ant Cardiocondyla obscurior

Frontiers in Neuroanatomy, 2015
A wide spectrum of occupied ecological niches and spectacular morphological adaptations make social insects a prime object for comparative neuroanatomical studies. Eusocial insects have evolved complex societies based on caste polyphenism.

Ecological Niche Adaptations Influence Transposable Element Dynamics in Pollinating and Non-Pollinating Fig Wasps. [PDF]

Ecol Evol
The influence of ecological niches on transposable element (TE) dynamics, particularly in mutualistic relationships, remains understudied. This research reveals that non‐pollinating fig wasps (NPFWs) have “aggressive,” expansion‐driven TE landscapes with active insertions, contrasting with the stable, “dormant” TE profiles in pollinators.
