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

Arboreal ant colonies as 'hot-points' of cryptic diversity for myrmecophiles: the weaver ant Camponotus sp. aff. textor and its interaction network with its associates. [PDF]
PLoS ONE, 2014 INTRODUCTION:Systematic surveys of macrofaunal diversity within ant colonies are lacking, particularly for ants nesting in microhabitats that are difficult to sample.

Population Diversity in Ant-inspired Optimization Algorithms
Computer 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.

Effects of Peri-Urbanization on Coastal Sage Scrub Ant Species in Baja California
Diversity, 2023 Increasing urbanization on the Baja California Peninsula threatens ant diversity. Reductions in ant species diminish ecosystem services provided to semiarid coastal scrub areas.

Scientific Reports, 2021 Fragmented natural habitats within human-transformed landscapes play a key role in preserving biodiversity. Ants as keystone species are essential elements of terrestrial ecosystems; thus, it is important to understand the factors influencing their ...

Promoting Search Diversity in Ant Colony Optimization with Stubborn Ants
Procedia Computer Science, 2012 AbstractIn ant colony optimization (ACO) methods, including Ant System and MAX-M IN Ant System, each ant stochastically generates its candidate solution, in a given iteration, based on the same pheromone T and heuristic η information as every other ant.

Macroecology and macroevolution of the latitudinal diversity gradient in ants [PDF]
Nature Communications, 2018 AbstractThe latitudinal diversity gradient—the tendency for more species to occur toward the equator—is the dominant pattern of life on Earth, yet the mechanisms responsible for it remain largely unexplained. Recently, the analysis of global data has led to advances in understanding, but these advances have been mostly limited to vertebrates and trees ...

Agronomy, 2022 We aimed at assessing the role of ecological infrastructures (EI) in promoting ant biodiversity in floodplain Mediterranean agricultural crops. We examined and compared ant communities at the interface between EI (remnant vegetation patches) and ...

Ant recognition cue diversity is higher in the presence of slavemaker ants [PDF]
Behavioral Ecology, 2015 Social insect colonies defend themselves from intruders through nestmate recognition, yet the evolution and maintenance of recognition cue diversity is still poorly understood. We compared the recognition cue diversity of 9 populations of Temnothorax longispinosus ant colonies, including populations that harbored the socially parasitic slavemaker ant ...
