The effects of anthropogenic disturbance and seasonality on the ant communities of Lang Tengah Island [PDF]

open access: yesPeerJ, 2023
Anthropogenic disturbances and seasonal changes significantly impact diversity and community composition of ants, but their effects are often intertwined.

Effects of Vegetation Structure on Ant Diversity in Different Seasonal Periods in Impacted Fragments of Atlantic Forest

open access: yesSociobiology, 2023
The destruction of forest habitats generates extremely fragmented areas and changes in vegetation structure. That changes the characteristics of microhabitats and the availability of resources and affects the diversity of animal species such as ants ...

Unrecognized Ant Megadiversity in Monsoonal Australia: Diversity and Its Distribution in the Hyperdiverse Monomorium nigrius Forel Group

open access: yesDiversity, 2022
We document diversity and its distribution within the hyperdiverse Monomorium nigrius Forel group of the Australian monsoonal tropics, an unrecognized global centre of ant diversity.

Local environmental variables are key drivers of ant taxonomic and functional beta-diversity in a Mediterranean dryland

open access: yesScientific Reports, 2021
The decomposition of beta-diversity (β-diversity) into its replacement (βrepl) and richness (βrich) components in combination with a taxonomic and functional approach, may help to identify processes driving community composition along environmental ...

The ant fauna (Hymenoptera: Formicidae) of the Mordovia State Nature Reserve, Russia

open access: yesNature Conservation Research: Заповедная наука, 2021
Ants form an important insect group in many terrestrial ecosystems. The research of ant species diversity is a relevant line of ecological and faunistic studies to completely reveal the biodiversity. Particular attention is given to Protected Areas where

Ant Species Diversity in the Central and Northern Parts of the Western Sichuan Plateau in China

open access: yesDiversity, 2023
Understanding how species richness changes along elevational gradients has attracted increasing attention from many researchers. The relationships between species richness and elevations were characterized by monotonic decreases or mid-elevational peaks.

Community structure of ants (Hymenoptera: Formicidae) in an open habitat: the importance of environmental heterogeneity and interspecific interactions

open access: yesRevista Mexicana de Biodiversidad, 2022
Ant species are highly sensitive to environmental changes, and ant community structure can be shaped by environmental heterogeneity and interspecific interactions.

Double Ant Colony Algorithm Based on Collaborative Mechanism and Dynamic Regulation Strategy

open access: yesJisuanji kexue yu tansuo, 2021
Aiming at the problem that the ant colony algorithm has slow convergence rate and poor diversity in solving traveling salesman problem (TSP), double ant colony algorithm based on collaborative mechanism and dynamic regulation strategy is proposed ...

Partitioning the impact of environment and spatial structure on alpha and beta components of taxonomic, functional, and phylogenetic diversity in European ants [PDF]

open access: yesPeerJ, 2015
We analyze the relative contribution of environmental and spatial variables to the alpha and beta components of taxonomic (TD), phylogenetic (PD), and functional (FD) diversity in ant communities found along different climate and anthropogenic ...
