Taxonomic notes

Synonyms: A. artemisiifolia Linnaeus var. elatior (Linnaeus) Descourtils; A. artemisiifolia Linnaeus var. paniculata (Michaux) Blank; A. artemisiifolia Linnaeus var. artemisiifolia; A. elatior Linnaeus; A. monophylla (Walter) Rydberg; A. glandulosa Scheele

Description

Annual. Are rhizomatous, perennial herb with pubescent stems and usually freely branched. The leaves are opposite, the upper are alternate, linear, 1-4.5cm long, 0.5-3mm wide, entire, the base are attenuate, and pubescent on both surfaces. The petioles are obscured by decurrent blade tissues. The racemes are 3-20cm long. The involucres are 1.5-3mm long. The nutlets are black in color, are pubescent at the apex, obovoid in shape, turgid, and 1.6-2.1mm long. Flowers September to October.[1]

Annual. Grows 0.2-2m tall, with a taproot. Has freely branched stems. The leaves are deeply bipinnately dissected with acute sinuses, the lower are opposite, the upper are alternate, 5-15cm long. The segments are mostly less than 1cm wide and are acute. The pistillate involucres are fascicled in upper leaf axils, obovoid in shape, pubescent to glabrate, 2.5-3.5mm long, 1.5-2.5mm in diameter, angulate, each with 5-6 rarely fewer, erect projections toward the apex. The staminate heads are 2-4mm broad, irregularly more or less 5-lobed, peduncles 1-6mm long. The nutlets are brown in color and 3-3.5mm long. Flowers August to frost.[1]

Distribution

A. artemisiifolia is distributed across the continental United States as both a native and introduced species, and is native to almost all provinces of Canada. It has also been introduced to Hawaii. [2]

Ecology

Habitat

It is common throughout Florida.[3] and throughout the entire United States.[4] It has been found in open pine woods, mixed hardwoods, wet hammocks, and along dried up shores of ponds. It does well in a number of disturbed areas including old fields, drainage ditches, pastures, roadsides, sandy vacant lots, railroad gravel, blackland prairie soil, camping areas, wet pastures, levees, drainage ditches, along edges of mixed forests, recently disturbed boggy areas, along canals, and agricultural fields. It thrives in dry sandy soils to wet, peaty soils in high intensity light in open areas.[5] A. artemisiifolia has been observed to be negatively impacted by soil disturbance in northeast Florida.[6]. It does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[7]

Associated species include Agalinis divaricata, pine, hickory; Euphorbia, Andropogon, Bidens, Paspalum urvillei, P. notatum, Eragrostis oxylepis, Eleusine indica, Digitaria sanguinalis, Cyperus surinamensis, Ambrosia artemisifolia, Strophostyles helvola, Solanum americanum, S. sisymbriifolium, Daubentonia drummondii, Sesbania exaltata, cabbage palmetto, Emilia fosbergii, Paspalum setaceum, Heterotheca subaxillaris, Boerhavia diffusa, Bothriochloa ischaemum; Croton capitatus and various grasses.[5]

Phenology

Ambrosia artemisiifolia has been observed to flower between April and June to November and fruits from summer to late fall.[3][5][8]

Seed dispersal

Seeds are primarily distributed by animals,[9] but this species is also thought to be dispersed by wind.[10]

Seed bank and germination

It has a persistent seedbanks that can remain in the soil even after years of disturbance.[11] Seeds require an after-ripening period before germination occurs; germination occurs after near freezing temperatures.[12] While this is true, it is quite successful in seed germination due to being able to germinate in a large range of variable conditions, including temperatures between 5 to 40 degrees Celsius.[13] The initial dormancy of A. artemisiifolia can be attributed to presence of inhibitors like phenolic compounds and abscissic acid.[14]

Fire ecology

It can live where winter-burned annually and has been found in firelanes of annually-burned pinelands.[5][15] While fire increases the amount of bare ground, this in turn decreases competition and allows weedy forbs like A. artemisiifolia to greatly increase in numbers.[16] As well, A. artemisiifolia has been shown to proliferate with a high number of fire treatments.[17]

Use by animals

A. artemisiifolia is one of the most important plant species for food and cover-producing for northern bobwhite quail.[18] The seeds are also consumed and utilized by various songbirds, the thirteen line ground squirrel, prairie deer mice, meadow vole, and prairie vole.[9] It is a common plant for white-tailed deer to browse in the Spring and Summer months.[18][19][20][21] The following caterpillars eat the foliage, flowers and seeds: Schinia rivulosa (ragweed flower moth), Synchlora aerata (wavy lined emerald), Tarachidia erastrioides (small bird dropping moth), and Tarachidia candefacta (olive shaded bird dropping moth).[9]

Diseases and parasites

The pathogenic fungus Albugo tragopogi (white rust fungus) attacks ragweed and decreases pollen production. It is used as a control agent to limit the amount of ragweed allergens.[22]

Conservation and management

Ragweed is a common allergen. While mowing A. artemisiifolia multiple times can reduce airborne pollen, this method of management does not affect the seed bank and would not stop the species from regerminating.[23] However, the pathogenic fungus Albugo tragopogi (white rust fungus) can be used as a control agent to limit the amount of ragweed pollen produced.[22] A. artemisiifolia is listed as a noxious weed within city limits in the state of Illinois, and listed as a "B" designated weed and quarantined in the state of Oregon.[2]

Cultivation and restoration

Historically, A. artemisiifolia was used by the Oto Native American tribe in the Missouri River region as a remedy for nausea. It was used on the surface of the abdomen, where the patient was scarified and then dressed with the bruised leaves.[24] It was also utilized by the Houma tribe in Louisiana for menstruation pain by making a tea out of the boiled roots.[25]
