The subphylum Hexapoda (from Greek for 'six legs') or hexapods comprises the largest clade of arthropods and includes most of the extant arthropod species. It includes the crown group class Insecta (true insects), as well as the much smaller clade Entognatha, which includes three classes of wingless arthropods that were once considered insects: Collembola (springtails), Protura (coneheads) and ...
Beginning in the 1990s, molecular (DNA sequence) data have come to play a central role in attempts to reconstruct the ant "tree of life".Molecular phylogenetic analyses based on multiple nuclear genes have yielded robust results that reinforce some preexisting views but overturn others – and suggest that there has been considerable morphological convergence among some ant lineages.
The ants were fed honey-water containing varying isotopic solutions - phosphate, sulfate, or methionine. Sections of the plant were later cut, collected, and chloroformed to kill ants in order to perform an autoradiography. Different areas of the plants were tested in order to compare the different depositions and uptake from the various surfaces.
The ant climbs up the stem of a plant and uses its mandibles with abnormal force to secure itself to a leaf vein, leaving dumbbell-shaped marks on it. The ants generally clamp to a leaf's vein at a height of 26 cm above the forest floor, [ 10 ] on the northern side of the plant, in an environment with 94–95% humidity and temperatures between ...
Acacia-ant symbiosis is the interaction between myrmecophilous Vachellia trees (ant acacias) and ants that nest on them (acacia ants).Obligate acacia ants dwell in the gall-like domatia within the swolen stipular spines of African or Central American ant acacia species, and they also take the food (nectar or Beltian bodies) offered by the tree.
Hydnophytum is a genus of epiphytic myrmecophytes (ant plants) native to Southeast Asia, the Pacific region and also extending into Queensland in northern Australia. The name is derived from the Ancient Greek hydnon "tuber", and phyton "plant", after their appearance with their swollen succulent stems.
Replacing red meat with plant-based protein sources such as nuts and legumes was associated with a 19% lower risk of dementia and 1.37 fewer years of cognitive aging, according to the study.
An ant garden. An ant garden is a mutualistic interaction between certain species of arboreal ants and various epiphytic plants. It is a structure made in the tree canopy by the ants that is filled with debris and other organic matter in which epiphytes grow. The ants benefit from this arrangement by having a stable framework on which to build ...
