Experimental warming weakens positive plant diversity effects on pitfall trap sampled ant diversity

open access: yesSoil Organisms, 2022
Ants are important components of many terrestrial ecosystems because of their high abundance, their central position in food webs, and because they can strongly influence ecosystem properties such as soil aeration, nutrient cycling, and plant community ...

Identify and analyze the Diversity of Ant in Indonesia, Diversity of Ants at the Universitas Sumatera Utara and Diversity of Ants at The Universitas Andalas

open access: yesInternational Journal of Ecophysiology, 2022
One of the diversity of subfamily level ants is Myrmicinae. Myrmicinae are distributed throughout the world in all major habitats except ecosystem areas with low diversity indicating pressure that will affect ecosystem quality. The types of ants obtained from the location of the USU campus found 9 species consisting of 5 subfamilies as follows ...

ECOLOGICAL RELEASE OF AN EXOTIC SPECIES UPON SUPPRESSION OF ITS INVASIVE PREDATOR: A FIVE-YEAR CASE STUDY, WITH NOTES ON OTHER SPECIES, AND THE LIFE HISTORY OF THE MEDITERRANEAN GECKO, HEMIDACTYLUS TURCICUS [PDF]

open access: yes, 2014
Ecological release allows a species to expand beyond its currently occupied niche upon removal of a limiting mechanism such as a predator or competitor. Unfortunately, these interactions between exotic and invasive organisms are relatively unknown.

Population Diversity in Ant-inspired Optimization Algorithms

open access: yesComputer Science, 2021
Finding a balance between exploration and exploitation is very important in the case of metaheuristics optimization, especially in the systems leveraging population of individuals expressing (as in Evolutionary Algorithms, etc.) or constructing (as in Ant Colony Optimization) solutions.

Adaptive multimodal continuous ant colony optimization [PDF]

open access: yes, 2017
Seeking multiple optima simultaneously, which multimodal optimization aims at, has attracted increasing attention but remains challenging. Taking advantage of ant colony optimization algorithms in preserving high diversity, this paper intends to extend ...
