INTRODUCTION Lyme disease (Lyme borreliosis, LB) is a systemic tick-borne disease. Its symptoms include dermatological changes and systemic manifestations such as musculoskeletal, neurologic, and cardiac. The etiologic agent of LB is a spirochete known as Borrelia burgdorferi (B.b.) with rodents and small mammals as its animal reservoir. In Poland, there are approximately 9-10 cases of the dise...

Northern red oak (Quercus rubra) and white oak (Quercus alba) are important components of high-quality mes1c s1tes and are essential as lumber species and hard mast producers. Regeneration of these species has been difficult, and their absence in newly regenerated stands is a major concern of foresters and wildlife biologists Several 1mportant biolog1cal tra1ts of oak species may contribute to ...

Faustmann showed us the basic economic formulation of the forestry problem 163 years ago. However, since then foresters and economists have learned of a number of situations in which Faustmann’s marvelous contribution is incomplete, inaccurate, or inappropriate. Our more recent experience addresses some of those situations—but we do not have fully accepted answers for all of them. This paper id...

Oregon State University • University of Idaho • Washington State University Wood has long served as one of our most versatile and heavily used raw materials. From it we derive solid wood for structural and ornamental applications, composite products in the forms of panels and beams, numerous paper products, chemicals, fuel—the list could go on and on. Foresters have worked for many years to inc...

In the past 30 years, phosphate fertilization has been widely used by foresters in Landes de Gascogne. During this same period, several growth disturbances and malformations without pathological affections have appeared in pines and particularly in 3 yr old pines (twisting of branches and leaders, abundant fascicle shoots, loss of apical dominance, die-back of the top and production of unlignif...

The reverse-J shaped curve, and specific versions of it, have become synonymous with unevenaged silviculture in American practice. It has its role, but there are other alternatives. It is important to understand the goals of silviculture and the biological assumptions behind the use of a reverse-J curves, before using them to develop practical marking guides. At the same time, it is important f...

Providing ready-for-practice materials in an easily accessible and user-friendly way is one of the challenges Horizon 2020 Thematic Networks (TNs) to promote agriculture forestry innovation. Those are result co-creation knowledge exchange among TN actors. Using a survey, we investigated most efficient communication dissemination (C&D) channels, types formats TN-produced data, as well involv...
