Fraxinus americana 'Autumn Purple': 'Autumn Purple' White Ash

open access: yesEDIS, 2014
`Autumn Purple' White Ash is a male tree introduced in 1956, growing 40 to 50 feet tall and perhaps 35 to 50 feet wide, and is a cultivar of the species which is native to moist locations.

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

Fraxinus pennsylvanica 'Summit': 'Summit' Green Ash

open access: yesEDIS, 2014
`Summit' Green Ash grows into a pyramidal form when young, maturing to a rather open, oval silhouette 55 feet tall by 50 feet wide. Once developed properly in the nursery, the trunk remains straight up through the crown of the tree and the branch habit ...

Deciduous trees and the application of universal DNA barcodes: a case study on the circumpolar Fraxinus. [PDF]

open access: yesPLoS ONE, 2012
The utility of DNA barcoding for identifying representative specimens of the circumpolar tree genus Fraxinus (56 species) was investigated. We examined the genetic variability of several loci suggested in chloroplast DNA barcode protocols such as matK ...

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

open access: yesThe Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Needle in a haystack: Holocene history of European larch in Central Europe revisited

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

Fraxinus americana: White Ash

open access: yesEDIS, 2014
White Ash is resistant to heat, although it is native to moist locations, including river bottoms and well-drained upland sites. It grows 50 to 80 feet tall and wide.

Synthetic Imagery Improves Ecological Classification When Real Data Are Scarce, Not Direct Substitutes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Image generation models can create synthetic ecological datasets and potentially alleviate limitations from sparse real data. Using 20 tree genera across community‐science and street‐view imagery, we tested whether synthetic images could replace or supplement real data for image classification.

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.
