 Popweb: Alnus Glutinosa - Palaeoecology
Alnus pollen is recorded throughout the Hoxnian Interglacial (Oxygen Isotope Stage 7 or 9) and is particularly abundant in the mid-interglacial warm phases at several sites in East Anglia and the Midlands of England, when a strong macrofossil record also occurs (Godwin 1975).
Alnus macrofossils have been reported in an early Holocene context in the south of England (Clarke and Barber 1987, Waller 1993) but Alnus pollen frequencies, although widely present (Chambers and Elliott 1989), remain very low in the early stages of the present interglacial (Bennett and Birks 1990).
As Alnus is a high pollen producer and its pollen is well transported by wind and water, these low frequencies suggest no major local populations of alder around these sites at this time, although the existence of small isolated populations remains possible.

 Trees of Wisconsin: Alnus incana, speckled alder
Alnus incana can occasionally grow to tree size, but is most often considered a large shrub.
Flowers of Alnus incana are in the form of conspicuous, elongate aments (catkins) of male flowers and much smaller reddish aments of female flowers, lacking outer scales ("naked" female ament buds).
The largest individual of Alnus incana known in the state of Wisconsin is located in Brown County.

 Trees of Wisconsin: Alnus viride, green alder
Alnus viridis is a most often a shrub (perhaps occasionally a small tree) with simple, alternate, finely toothed leaves.
The female aments (catkins) of Alnus viridis are covered by exterior bud scales and the winter leaf buds are covered by 3 or more imbricate outer scales and they are short-stalked.
Alnus viridis is much less common in Wisconsin than Alnus incana, being relatively common mostly in the counties near Lake Superior.

Alnus rubra is the scientific name of the red alder so abundant in western Oregon.
The first word (Alnus) is the genus name for alders and the second word (rubra, meaning red) is the specific epithet.
The word Alnus tells you that the species is an alder and the specific epithets define which species of alder you are talking about.

 Ecology: Aphid performance in an alder hybrid zone - Alnus
The growth and reproduction of the aphid Pterocallis alni when feeding on alders (Alnus sp.), are determined by temperature.
The aphid Pterocallis alni is restricted to the genus Alnus in Britain and its population biology has been well studied (Gange 1985).
In addition, it is a free-living insect, thus providing a contrast to the majority of insect/plant hybrid studies, which have involved endophagous insects, such as gallers or leaf miners.

 Thursday's Plant -- Alnus cordata   (Site not responding. Last check: 2007-10-20)
The Italian alder, Alnus cordata, although commercially available, is often overlooked by growers and landscapers, who perhaps mistakenly believing it to be more culturally demanding than it really is.
Because other Alnus species have interestingly notched leaves and other variations that give the foliage more character, Italian alder needs additional traits to justify its use as a landscape tree.
As with any plant, it is important to value a species based on all of the aesthetic and utilitarian merits it has collectively.

It grows with vigour, reaching about 10m in height, and has an ideal shape for single row planting as a windbreak.
Perhaps the most significant attribute of Alnus cordata is that its roots have a vertical orientation.
This renders root penetration of nearby crops unlikely, and enables their planting relatively close to irrigated horticultural rows.
