The intertwined population biology of two Amazonian myrmecophytes and their symbiotic ants
ant–plant interactions Cordia nodosa demography
2015/12/10
A major question in ecology is: how do mutualisms between species affect
population dynamics? For four years, we monitored populations of two Amazonian
myrmecophytes, Cordia nodosa and Duroia hirsut...
Colony variation in the collective regulation of foraging by harvester ants
Colony variation harvester ants
2015/12/10
This study investigates variation in collective behavior in a natural population of colonies of the harvester ant, Pogonomyrmex
barbatus. Harvester ant colonies regulate foraging activity to adjust t...
Neither Ants nor Hermites
knowledge learning organization teamwork leadership trusted competency bioteaming collective behaviour
2015/7/29
Acceleration of renewal of technologies make management more complex and induces organizations to absorb more and more knowledge, in less and less time; of course each member of the organization accom...
Harvester ants use interactions to regulate forager activation and availability
collective behaviour complex system
2015/12/10
Social groups balance flexibility and robustness in their collective response to environmental changes
using feedback between behavioural processes that operate at different timescales. Here we...
Water Stress Strengthens Mutualism Among Ants, Trees, and Scale Insects
Ants, Trees Scale Insects
2015/11/13
Abiotic environmental variables strongly affect the outcomes of species interactions. For example, mutualistic interactions
between species are often stronger when resources are limited. The effect m...
Diversification and phylogeographic structure in widespread Azteca plant-ants from the northern Neotropics
ant–plant mutualism Cordia alliodora gene trees
2015/12/10
The Neotropical myrmecophytic tree Cordia alliodora hosts symbiotic Azteca ants in
most of its widespread range. The taxonomy of the genus Azteca is notoriously difficult,
which has frequently obscu...
Effects of Vegetation Cover, Presence of a Native Ant Species, and Human Disturbance on Colonization by Argentine Ants
edge effect Prenolepis imparis propagule pressure vegetation cover
2015/12/10
The spread of non-native invasive species is affected by human activity, vegetation cover, weather,
and interaction with native species. We analyzed data from a 17-year study of the distribution of t...
Diversification and phylogeographic structure in widespread Azteca plant-ants from the northern Neotropics
ant–plant mutualism Cordia alliodora gene trees
2015/11/13
The Neotropical myrmecophytic tree Cordia alliodora hosts symbiotic Azteca ants in
most of its widespread range. The taxonomy of the genus Azteca is notoriously difficult,
which has frequently obscu...
The effect of individual variation on the structure and function of interaction networks in harvester ants
agent-based model movement pattern network analysis
2015/12/10
Social insects exhibit coordinated behaviour without central control. Local interactions
among individuals determine their behaviour and regulate the activity of the colony.Harvester ants are recruit...
Hybrid ANFIS-ants system based optimisation of turning parameters
Machining Turning optimization ANFIS-Ants technique
2009/12/14
Purpose: The paper presents a new hybrid multi-objective optimization technique, based on ant colony optimization algorithm (ACO), to optimize the machining parameters in turning processes.
Design/me...
Review of "Ants, Bikes & Clocks: Problem Solving for Undergraduates", by William Briggs
Undergraduates William Briggs the mathematical passages
2010/2/26
Probably, most of the students who have taken (or will take) undergraduate courses based on the so-called exact sciences have faced (or will face at some point) the terror of being unable to solve som...
