Evaluation of Resistance to the Beech Scale Insect (Cryptococcus fagisuga) and Propagation of American Beech (Fagus grandifolia) by Grafting [PDF]
Silvae Genetica, 2007 Abstract Scions collected from diseased trees and from those without symptoms of beech bark disease (BBD) were cleft-grafted in 2003 and 2004 onto rootstock of unknown resistance to BBD. Grafting success varied among genotypes and year (30% in 2003 and 12% in 2004), and improved with increasing rootstock diameter. Successful grafts were

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans
Integrative Zoology, EarlyView.An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Partial harvest to reduce occurrence of American beech affected by beech bark disease: 10 year results [PDF]
Forestry: An International Journal of Forest Research, 2017 Beech bark disease stunts American beech (Fagus grandifolia Ehrh.) to unmerchantable size, and promotes heavy sprouting that outcompetes more desirable sugar maple (Acer saccharum Marsh.) and yellow birch (Betula alleghaniensis Britt.). We investigated whether selection harvest targeting removal of large beech can promote maple and birch regeneration ...

Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads
The RAND Journal of Economics, EarlyView.ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

Allergy, EarlyView.The spectrum of allergic sensitization in mothers and their offspring was characterized at ages 1–5 years at an extract‐ and molecular level in a North American birth cohort. Fel d 1 was the primary sensitizer in mothers, followed by Phl p 1. Perennial allergen sensitization (Der f 1, Der p 1) was rare at age one but rose sharply by age five.

Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.
