Produktion, skador och grenegenskaper hos 10-årig tall i ett kombinerat förbands- och avkommeförsök : Volume production, damages and branch properties in a 10-year old combined spacing and progeny trial of Scots pine

A Scots pine (Pinus sylvestris) progeny trial was established in 1990, in the southwestern part of Sweden. The offspring was from 30 plus trees. The trial is located on abandoned agricultural land and has a single tree block design with a variation in spacing. The trial has been damaged by voles. At a tree age of ten years, growth, damages and branch properties were estimated. An analysis of variance on height, diameter and stem volume shows significant difference between spacing and progenies as well as interactions between these factors. As indicated by a better annual height increment and fewer and thinner branches at each whorl the densest spacing has the highest potential to produce quality logs.There were also differences between progenies in growth and quality traits. Some progenies combined good growth and branch characters with low mortality, straight stems and few damages. Other progenies had superior volume production.

Review of <i> Global Warming in the 21st Century. Volume 1: Our Evolving Climate Crisis; Volume 2: Melting Ice and Warming Seas; Volume 3: Plants and Animals in Perili> by Bruce E. Johansen

There is compelling evidence that Planet Earth is on the path to an era of global warming that has serious implications for the well-being of both people and nature. This three-volume synthesis of literature will be a marvelous place for both the public and new scholars interested in global warming to begin their pursuit of the subject. The author captures the best of the scientific literature and press materials appearing in recent years. The utility of these volumes as a resource for gaining a broad background or pursuing a particular aspect of global warming is enhanced by Johansen's talent for explaining with clarity a vast and rapidly growing subject.

I. Charlestown ferry bound volume, 1707-1806

This series contains sixty-nine documents related to the College's interest in the Charlestown ferry between 1707 and 1806 that were gathered together, arranged in chronological order, and pasted into a bound volume at an undetermined date. The majority of documents are leases and bonds with the ferrymen, as well as handwritten copies of Corporation petitions to the General Court regarding ferry fares and bridge development. The series also includes handwritten legal opinions composed by Levi Lincoln and Nathan Dane for the College analyzing the rights of the College to transportation-related income.
