Taxonomic Notes
Varieties: A. rubrum Linnaeus var. rubrum; A. rubrum Linnaeus var. trilobum Torrey & A. Gray ex K. Koch.; A. rubrum L. var. drummondii Hook. & Arn. ex Nutt. Sarg.[1][2]
Synonyms: Rufacer rubrum (Linnaeus); Rufacer
carolinianum (Walter).[1]
Description
A. rubrum is a deciduous perennial tree that can reach heights of 60 to 75 ft (18.3-22.9 m) with a spread of 25 to 35 feet (7.6-10.7 m). Unless growing next to a water source, individuals in the southern portion of its range tend to be shorter than northern individuals. Leaves are simple with lobed, incised, and serrated margins.[4] In cooler climates (e.g. Rhode Island), leaves tend to have more teeth and are more highly dissected than in warmer climates (e.g. Florida).[5] The leaves have palmate venation and are arranged opposite or sub-opposite. During the spring and summer the leaves are green, but in the fall they change to orange, red, and yellow before falling from the tree.
A. rubrum is classified as polygamodioecious, meaning the population is a mixture of dioecious (separate male and female trees), monoecious (separate male and female flowers on the same tree), and bisexual (flowers with both male and female organs on the same flower) individuals.[6] The flowers are red and produce an elongated red fruit of 1 to 3 in (2.5-7.6 cm) in length with a dry, hard covering.[4] Roots are primarily horizontal, being found in the upper 9.8 in (0.25 m) of soil.[7]
Distribution
A. rubrum occurs throughout the eastern United states including parts of Texas, Oklahoma, Missouri, Iowa, and Minnesota. This range includes the entirety of the southeastern United States Coastal Plain where all three variations of the the species are found. It can also be found in parts of Oregon and eastern Canada.[2]
Ecology
Habitat
Within the Coastal Plain A. rubrum has been observed in a variety of habitats including hardwood-cypress swamps, swampy woodlands, hammocks, wooded ravines and slopes, along shorelines, floodplain forests, mesic woodlands, and beech-magnolia deciduous forests,[8] but is most abundant in bottomlands.[3] This tree is known to quickly become established in areas disturbed by fire, logging, and agriculture, and they are also tolerant of waterlogged soils and flooding, making it a "super-generalist" among those that grow on the widest variety of sites and in the greatest range of conditions in North America.[3]
Despite their ability to aggressively colonize disturbed, wet, and shady areas, A. rubrum is intolerent of frequent fires[3][9] and areas where saltwater inundation can occur,[10] and it was found to respond negatively to clearcutting and chopping in a flatwoods forest in northeast Florida.[11] Additionally, Acer rubrum has been found to be a decreaser in its short-term response to single mechanical soil disturbances.[12]
Acer rubrum is frequent and abundant in the Calcareous Savannas community type as described in Carr et al. (2010).[13]
Phenology
A. rubrum has been observed to flower between January and April[3][14] with fruiting occurring between April and June.[3]
Seed dispersal
Trees as young as 4 years can begin producing[3] double samara seeds (two connected winged fruits) which separate as they mature.[15] As the seed falls from the tree, the samara rotates producing lift and limiting the terminal velocity of the seed.[16] Distances seeds travel is highly correlated with wing loading potentials, a seed's initial height, and the velocity of the wind.[16][17]
Seed bank and germination
95% of viable seeds germinate within 10 days of dispersal allowing A. rubrum seedlings to establish themselves 3-4 months before other associated woody species.[3]
Fire ecology
The thin bark and lower rates of resprouting cause A. rubrum to be considered a fire intolerant species, although it typically resprouts following fire.[3][9] Although a single fire event can reduce seedling and sapling densities, it is quick to recolonize to pre-burn levels within four growing seasons via seedlings and resprouts.[18] Populations of Acer rubrum persist through repeated annual burns.[19]
Scorching is also common among A. rubrum, especially during high wind and temperatures.[4]
Pollination and insect hosting
Acer rubrum is an important species for weakened overwintered pollinators such as honey bees. This is because A. rubrum blooms before most vernal plants and possesses masses of conspicuous, fragrant flowers abundant in nectar and pollen. Common pollinators include species from Tenthredinidae (sawflies), Braconidae (parasitoid wasps), Colletidae (plasterer bees), Andrenidae (solitary ground-nesting bees), Halictidae (sweat bees), Megachilidae (mason and leafcutter bees), Apidae (bumblebees, honey bees, carpenter bees, orchid bees, cuckoo bees), Vespidae (eusocial wasps and many solitary wasps), Calliphoridae (blow flies), Scathophagidae (dung flies), Syrphidae (hoverflies), Tachinidae (true flies), and Coccinellidae (ladybugs).[20].[21]
Herbivory and toxicology
Seeds of A. rubrum are consumed by many different species of squirrels, birds, and other mammals.[4] Depredation of seeds tend to increase with the age of old field habitat and is higher in woody habitats compared to herbaceous habitats.[22]
A. rubrum can also influence ecological interactions of newts and frogs through the effects of its leaf litter on water quality.[23]
Diseases and parasites
A. rubrum is susceptible to a variety of parasites and diseases. Leaf stalk borers and petiole-borers will bore into the leaf stalk, just below the leaf blade, causing the leaf stalk to shrivel, turn black, and the leaf blade to fall off. Gall mites stimulate round growths/galls to form on leaves which can range in color, including green, red, and black. While galls are not considered serious, they can reach numbers great enough to cause individual leaves to curl up. Anthracnose can cause light brown or tan areas on leaves, but is more common during rainy seasons.[4]
Conservation, cultivation and restoration
Cultivars include 'Armstrong', 'Autumn Flame', 'Bowhall', 'Gerling', 'October Glory', 'Red Sunset', 'Scanlon', 'Schlesinger', and 'Tilford'. These cultivars range in fall leaves color, overall tree height, and regional adaptations. A hybrid cross between Red and Silver Maple named Hybrid Maple is available (Acer x fremanii) with cultivars including 'Armstrong', 'Autumn Blaze', 'Celebration', 'Celzam', and 'Scarlet Sentenial'.[4]
Cultural use
Maples have long been an excellent source of sugar, sap, and syrup. This particular species does not produce the highest yields, but is still a useful source of these sweet products. Sugaring used to be an event in the spring in early America. People would go out and collect the sweet resources from the maple trees for use as treats, syrup, and sugar.[24]
Native Americans would use the bark to make bread flour, and the Kalmyk people would harvest and cook the seeds to eat.[24]
