Effect of Time-Since-Fire on Ant Communities in a Semi-Arid Landscape. [PDF]
Ecol EvolWe sampled ants from five sites with varying fire histories (3, 5, 9, 26, and 34 years since the last fire). A total of 16,360 ants were collected, and 59 species across 20 genera were identified. Our results indicate that total ant abundance was higher in recently burnt sites and decreased with increasing time‐since‐fire, while ant species richness ...

Ant Diversity and Stratification in an Amazonian Rainforest. [PDF]
Ecol EvolWe examined the three strata of an Amazonian rainforest (e.g., the ground and leaf litter, understory and canopy) using only two sampling techniques and analyzed their functional traits. We identified 494 ant species from 10 subfamilies and 77 genera over ≈3.0 ha, showing that they are species rich and abundant, particularly at ground level.

Vertical Stratification Increases the Capacity of Morphological Traits to Predict Trophic Position in Neotropical Ants. [PDF]
Ecol EvolWe use data from 73 Neotropical ant species to examine the strength of associations between nine morphological traits and trophic position. No individual morphological trait explained variation in the trophic position of arboreal species, whereas three traits individually correlated with the trophic position of ground species, but only weakly so ...

Distribution Pattern of Ants in Huanglianshan National Nature Reserve From Yunnan, China. [PDF]
Ecol EvolThis study found that ant diversity in the Huanglian Mountain National Nature Reserve exhibits a non‐linear distribution pattern along the altitudinal gradient, encompassing 209 species across 9 subfamilies and 66 genera. Elevation significantly structured ant communities in the reserve.

Journal of Insect Physiology, 2011 Workers of the ant species Ectatomma tuberculatum (Ectatomminae) have active ovaries and lay eggs that are eaten by the queen and larvae (trophic eggs). Vitellogenins are the main proteins found in the eggs of insects and are a source of nutrients.

Forest Cover and Geographic Distance Shape Ant Assemblages in the Southwestern Brazilian Amazon. [PDF]
Ecol EvolWe investigated how forest cover, precipitation, and spatial distance influence ant species richness and composition in the southwestern Brazilian Amazon. We found that forest cover increases species richness, especially of forest specialists, while spatial distance is the main driver of variation in species composition.

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