Abstract

SUMMARY (1) The influence of climatic factors on the growth of Pinus sylvestris was evaluated by comparing annual ring-widths from seven sites along an altitudinal gradient in Scotland with monthly climatic data. (2) Temperature was found to be more important than rainfall in influencing growth. Both late-winter (January-February) and summer (July-August) temperatures were significantly and positively correlated with ring-width. Winter browning or frost drought is a possible cause of the winter temperature correlation. (3) Krummholz trees, at the tree-line, were found to grow more, and their growth was less strongly correlated with climatic factors, than trees at lower elevations. It is suggested that this is due to their short stature and resultant higher tissue temperatures.

Abstract

Contains fulltext : 120237.pdf (Publisher’s version ) (Closed access) - Purpose - We investigate the implications of the misalignment between manager and shareholder interests and the effects of initial ownership stakes and reinvestment of unpaid dividends on managerial self-dealing. - Methodology - We collect and analyze data from controlled laboratory experiments with an experimental setting which captures the role of ownership in managerial considerations. - Findings - We see the emergence of both investor-aligned outcomes and managerial self-dealing outcomes. We find that increasing managers’ initial endowment of shares makes it harder for managers to coordinate on an outcome and lowers return on investment. Moreover, allowing managers to reinvest unpaid dividends results in a transfer of wealth to management. - Research limitations - The results and the conclusions are drawn upon data from the particular setting we investigate. Generalizing them beyond the specific setting should be done with caution. - Practical implications - Higher managerial ownership stake means that managers have a greater incentive to reward shareholders, but we find that it may also imply a more difficult coordination problem between managers – sometimes to the detriment of shareholders. - Originality - This study is the first to consider the direct relationship between managers’ portfolios and voting decisions regarding dividends and investment levels.

Abstract

The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Abstract

It is well known from history and prehistory that there are close relationships between environmental changes and the social, cultural, and economic development within a region. However, environmental impact assessment is a rather new field of research (e.g., Beanlands and Duinker, 1984), partly because of missing knowledge on the frequency and intensity of environmental changes in the past and of their causal mechanisms. Dendrochronology is one of several fields that can contribute to filling this gap.

Abstract

The systematic study of tree rings in western North America began with an intuitive insight by an astronomer, Andrew Ellicott Douglass. He was, before the turn of the 20th century, working at the Lowell Observatory in Flagstaff, Arizona, and was interested in the cyclic nature of solar activity, particularly sunspots, and its relation to terrestrial climate. Since the written record of solar activity extended further back in time than the record of terrestrial weather, he envisioned tree growth as a proxy measure of climate. Douglass’ investigation began in 1901 and was based on the following premises: that the rings of a tree are a measure of its food supply; that the food supply depends largely on the amount of available moisture, especially in drier climates where the quantity of moisture is limited and the life struggle of the tree is against drought rather than competing vegetation; and that therefore the rings are a measure of precipitation (Douglass, 1914, page 321). His method involved first the preparation of a treegrowth curve, and for this purpose pine (Pinus) trees growing in the environs of Flagstaff were chosen. In addition to convenience, these trees had two obvious advantages. First, the moisture available to the trees was primarily in the form of precipitation and, second, the average age of the trees was nearly 350 years, with some more than 500 years old (Douglass, 1914, page 322). This latter quality allowed a large backward extension of the growth curve in the record of a single tree.
