American Midland Naturalist, 1942 The state of Utah possesses a number of diversified habitats as to both topography and vegetation types. It lies entirely within the arid region of the United States, but there are high mountains separated by arid valleys and mesas. Sagebrush (Artemisia tridentata) ranges over a large portion of the State at the lower elevations.

Host plant use by competing acacia-ants : mutualists monopolize while parasites share hosts [PDF]
, 2012 Protective ant-plant mutualisms that are exploited by non-defending parasitic ants represent prominent model systems for ecology and evolutionary biology.

Strong μ‐faster convergence and strong μ‐acceleration of convergence by regular matrices
Mathematical Modelling and Analysis, 2008 The present paper continues the study of acceleration of convergence started in the paper [A. Aasma, Proc. Estonian Acad. Sci. Phys. Math., 2006, 55, 4, 195–209].

Do bromeliads affect the arboreal ant communities on orange trees in northwestern Costa Rica?
PLoS ONE, 2022 Ants often interact with other invertebrates as predators or mutualists. Epiphytic bromeliads provide nesting sites for ants, and could increase ant abundances in the tree canopy.

Negative effects of ant-plant interaction on pollination: costs of a mutualism
Sociobiology, 2021 The mutualism of ants and extrafloral nectary (EFN)-bearing plants is known to reduce rates of herbivory. However, ants may have negative impacts on other mutualisms such as pollination, constituting an indirect cost of a facultative mutualism.

Scientific Reports, 2021 Global pollinator decline is a major concern. Several factors—climate change, land-use change, the reduction of flowers, pesticide use, and invasive species—have been suggested as the reasons.

Morphophysiological differences between the metapleural glands of fungus-growing and non-fungus-growing ants (Hymenoptera, Formicidae). [PDF]
PLoS ONE, 2012 The metapleural gland is an organ exclusive to ants. Its main role is to produce secretions that inhibit the proliferation of different types of pathogens.

Cleaner Environmental SystemsIndustrial activities account for 28% of global greenhouse gas emissions, and many operational decisions at company (micro) and industrial park (meso) levels are taken without quantitative ex-ante assessment of their environmental and circularity impacts.

Urban tropical forest islets as hotspots of ants in general and invasive ants in particular
Scientific Reports, 2022 Urbanization is a crucial driver of environmental and biodiversity change. It is suggested that urbanization favours generalist and invasive species and might harm specialists of natural and semi-natural habitats.
