Synonyms: Erigeron strigosus Muhlenberg ex Willdenow[1]
Varieties: Erigeron strigosus Muhlenberg ex Wildenow var. strigosus; Erigeron strigosus Muhlenberg ex Willdenow var. septentrionalis (Fernald & Wiegand) Fernald; Erigeron strigosus var. beyrichii[1]
Description
A description of Erigeron strigosus is provided in The Flora of North America.
Distribution
Generally, E. strigosus can be found across the United States and Canada in all provinces except the northern provinces, and all states but Alaska, Hawaii, Nevada, Utah, and Arizona.[2] E. strigosus var. calcicola is found in the central basin of Tennessee, northwest Georgia, and northern Alabama. E. strigosus var. dolomiticola is endemic to Bibb county in Alabama. E. strigosus var. septentrionalis is scattered across northern North America, south to New York, Tennessee, Arkansas, Oklahoma, Wyoming, and California. Lastly E. strigosus var. strigosus is distributed from Nova Scotia west to Washington state, and south to central peninsular Florida as well as Texas.[1] Apomictic (reproduce asexually) populations usually have wider distributions than sexual populations.[3]
Ecology
Habitat
E. strigosus var. calcicola can be found in limestone glades, var. dolomiticola can be found in calcareous Ketona glades, var. septentrionalis can be found in roadsides and other disturbed areas, and var. strigosus can be found in open woodlands as well as roadsides and other disturbed areas.[1] In the Coastal Plain, E. strigosus can occur in upland old fields, sandy floodplains, turkey oak forests, lake shores, sandhill scrub oak-wiregrass communities, open oak woods, boggy slopes of longleaf pine savannas, and open limestone glades. In human disturbed areas it has been found along sandy roadsides, vacant lots, a disturbed sandhill growing with planted Pinus palustris and disturbed longleaf pine restoration sites. Soils include sand, sandy clay, loamy sand and sandy loam. [4] E. strigosus was found to be in its long-term response following cessation of repeated soil disturbance.[5]
Associated species include Liatris, Panicum, Leptoloma cognata, Baptisia megacarpa, Festuca, Piptochaetium, Verbena, Pinus palustris, Hymenopappus scabiosaeus, Phlox floridana, Stillingia sylvatica, Asimina longifolia var. spathulata, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceolata, Hedyotis crassifolia, Pterocauloon undulatum, Asclepias humistrata, Quercus hemisphaerica, Rhynchospora divergens, and Allium canadense. [4]
Phenology
E. strigosus has been observed flowering in February through October with peak inflorescence in May.[6][4] For the varieties, var. calcicola flowers from April or May until October, var. dolomiticola flowers from late May until October, and var. strigosus flowers from late April until October.[1] Overall, it begins flowering in March, with peak inflorescence in April and May, and sporadically flowers until October to early November, although it can flower outside of this normal time period.[3]
Seed dispersal
This species is thought to be dispersed by wind.[7]
Seed bank and germination
It is commonly found in the seed bank in the areas it is found, and germination rates increase after a fire disturbance. However, germination rates were seen to decrease with annual fire disturbance compared to four year burn regiments.[8]
Fire ecology
Generally, E. strigosus significantly increases abundance in response to fire disturbance,[9] and populations have been known to persist through repeated annual burns.[10][11] It commonly germinates in response to fire disturbance, and germination rates increase with fire disturbance rather than with no disturbance.[8] Increasing fire frequency overall has a positive affect on this species.[12] As well, E. strigosus benefits the most from a high fire return interval.[13] It also benefits more from springtime burn regiments rather than summertime burn regiments.[14]
Pollination
Erigeron strigosus has been observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Agapostemon splendens, Augochlorella aurata, Halictus poeyi and Lasioglossum placidensis[15] Other pollinators of E. strigosus include Dialictus placidensis, Halictus ligatus, Ceratina calcarata, Ceratina dupla, Ceratina strenua, Hylaeus mesillae, Hylaeus modestus, Augochloropsis sumptuosa and Lasioglossum pilosum.[16][17] It is also pollinated by the Karner blue butterfly (Lycaeides melissa samuelis).[18] Additionally, E. strigosus has been observed to host aphids such as Uroleucon sp. (family Aphididae), ground-nesting bees from the family Andrenidae such as Andrena brevipalpis, Andrena thaspii and Andrena wilkella, bees from the Apidae family such as Epeolus pusillus and Nomada articulata, plasterer bees from the Colletidae family such as Colletes mandibularis, Colletes simulans and Hylaeus coloradensis, sweat bees from the family Halictidae such as Agapostemon virescens, Augochlora pura, Halictus confusus, Halictus parallelus, Lasioglossum cinctipes, Lasioglossum hitchensi, Lasioglossum imitatum, Lasioglossum truncatum and Lasioglossum zonulum, true bugs such as Xyonysius californicus (family Lygaeidae), leafcutting bees from the family Megachilidae such as Heriades variolosa, Megachile pugnata, and Stelis lateralis, plant bugs such as Lygus lineolaris (family Miridae), and tree bugs from the family Membracidae such as Campylenchia latipes, Campylenchia sp.and Spissistilus festinus.[19] For grassland butterfly communities, E. strigosus is a very important nectar source due to its high density of flowering ramets compared to other flowering species in the same community.[20] As well, it is thought to be pollinated by flies in the Syrphidae and Tachinidae (Diptera) families.[21] This species is considered to be of special value since it attracts a large number of native bees for pollination.[22]
Herbivory and toxicology
E. strigosus consists of approximately 5-10% of the diet for various large mammals.[23] In the springtime, it is foraged by white-tailed deer.[24] This species supports conservation biological control through attracting predatory or parasitoid insects that in turn prey upon pest insects.[22]
Conservation, cultivation, and restoration
This species is considered to be weedy or invasive in Nebraska and the Great Plains region of the United States.[2]
For restoring prairie sites, E. strigosus can be utilized to help restore the community, and has been seen to persist in the seed bank as a site is being restored.[25]
