Novel Worker-Like Behavior Observed in Gynes of the Social Parasite <i>Tetramorium microgyna</i>. [PDF]

Ecol Evol
Our article reports, to our knowledge, the first observations of inquiline gynes performing worker tasks for their host colony. We dissected these gynes to establish that they were all unmated. We hypothesize that nest excavation by social parasites represents an artifact of a non‐parasitic past.

Niche Shifts Induce Major Changes in the Ranges of the World's Worst Invasive Ant Species. [PDF]

Ecol Evol
We detected strong positive associations between their niche and range shifts. Small niche shifts induced large range shifts in them. ABSTRACT Invasive ants have exerted major effects on global ecosystems and economic systems. Therefore, their future niche and range shifts have received more research attention; however, the shifts between their native ...

Recognition and Aggression of conspecific and heterospecific worker in Acromyrmex subterraneus subterraneus (Forel) (Hymenoptera: Formicidae)

Sociobiology, 2015
Aggressive behavior is important for social insects because it makes possible for the colony to defend itself and the offspring from the action of invasive species.

Metabolism And The Rise Of Fungus Cultivation By Ants [PDF]

, 2014
Most ant colonies are comprised of workers that cooperate to harvest resources and feed developing larvae. Around 50 million years ago (MYA), ants of the attine lineage adopted an alternative strategy, harvesting resources used as compost to produce ...

Colony size predicts division of labour in Attine ants [PDF]

, 2014
Division of labour is central to the ecological success of eusocial insects, yet the evolutionary factors driving increases in complexity in division of labour are little known.

Parasitismo e respostas comportamentais de Acromyrmex coronatus (Fabricius, 1804) e Acromyrmex crassispinus (Forel, 1909) (Hymenoptera: Formicidae) a Myrmosicarius catharinensis Borgmeier, 1928 (Diptera: Phoridae) em Londrina, PR

Semina: Ciências Agrárias, 2021
Formigas-cortadeiras do gênero Acromyrmex causam sérios prejuízos em áreas florestais cultivadas. Algumas moscas pertencentes à família Phoridae são conhecidas por parasitá-las e o resultado dessa interação pode fornecer bases promissoras para o manejo ...

Parasitoids of Acromyrmex (Hymenoptera: Formicidae) Leaf-Cutting Ants in Continuous and Fragmented Atlantic Forest

Sociobiology, 2014
Fragmentation of the habitat is a major threat to biodiversity in Atlantic forest. Parasitoids seem to be particularly susceptible to habitat fragmentation.
