Аннотация: One species of Citriobatus, one of Hymenosporum, and 13 of Pittosporum are recognized in the Papuasian region. Keys to and distribution maps of all of them and their intraspesific taxa are given. Diagnoses and the Papuasian distribution of previously known species of Pittosporum are included. A brief account of the ecology and phenology of the Papuasian species of Pittosporum is presented and related to evolution in the genus in the Papuasian and Malesian region. The genus is more diverse in Papuasia than elsewhere, from which conclusions relating to centres of origin and migration have been drawn.

Аннотация: The aim of this study is to analyze whether there are systematic differences in the flowering parameters, their geographical correlations or in adaption to climate between the two birch species. Are the effects of temperature and the light factor equal for both species, and do they differ from those controlling Norway spruce and Scots pine? Is Linsser's principle of proportional heat sums valid for birch species? This book studied and the other questions. To answer these questions, the within-year and the between-year variations in the timing of anthesis involved were measured and tested with the three parameters using two alternative reference points, median of anthesis and peak pollen catch day. The geographical variation of pollen catches was also measured and possible geographical correlations were sought.

material and methods -- female strobilus -- oviles -- progeny

Аннотация: Flowering phenology and flowering frequencies were investigated in clones offSwedish and Finnish origin growing in a pine seed orchard at Langtora. One purpose was to estimate the gene contribution of individual clones to the progeny. The frequencies of femeil and male strobili were estimated in 1973-1975. The onset and duration of both female receptivity and pollen dispersal were recorded. The pollen density in the seed orchard was estimated. Great clonal variation prevailed in the seed orchard with respect to the frequency of female and male flowering as well as the onset and duration of female receptivity and pollen dispersal. A good agreement in flowering frequencies and phenological characteristics of the clones between different years was observed. The calculations of the genetic composition of the progeny revealed that the gene contribution of the analysed clones varied considerably. This was mainly due to differences in the frequency of flowering.

Аннотация: The purpose of this study was to obtain information about moose feeding behaviour in young Scots pine stands in relation to tree density. This paper examins the following aspects: 1. The response of moose browsing to quantitative differences in food supply in terms of varying tree density. 2. Moose feeding preferences in relation to the nutritional status of food at low and high tree density. 3. The effcet of browsing in the young pine stand with respect to stem damage

anthesis -- flowering phenology -- pollen recording -- heat sum -- adaptation -- reinvasion

Аннотация: The aim of this study was to analyse the geographical variation found in the timing of anthesis in Scots pine. In the adaptaion of the generative cycle to local climatic conditions, the geographical adaptability weighted with the so called Linsser's law is a particularly intersting point. Geographical correlations calculated against distances measured along simulated post-glacial migration routes were stronger than purely latitudinal correlations. Effects of the reinvasion of Scots pine into Finland are thus still visible in pine populations. In light of flowering phenology it seems probable that the northern populations of Scots pine in Finland have still not completely adapted to the prevailing cold climate at these latitudes. A moderate warming of the climate would therefore be beneficial for Scots pine.

Аннотация: The aim is to study the amount of phenological variability in northern marginal stands and the effect of annual temperature sums of the previous two years on the timing of flowering and on amount of pollen production. The geographical adaptability of the generative cycle to local climate. The efficiency of two temperature sum systems, a linear and curvilinear one was compared with simple calendar time as delineators of generative development.

Аннотация: Alpine treelines mark the low-temperature limit of tree growth and occur in mountains world-wide. Presenting a companion to his book Alpine Plant Life, Christian Körner provides a global synthesis of the treeline phenomenon from sub-arctic to equatorial latitudes and a functional explanation based on the biology of trees. The comprehensive text approaches the subject in a multi-disciplinary way by exploring forest patterns at the edge of tree life, tree morphology, anatomy, climatology and, based on this, modelling treeline position, describing reproduction and population processes, development, phenology, evolutionary aspects, as well as summarizing evidence on the physiology of carbon, water and nutrient relations, and stress physiology. It closes with an account on treelines in the past (palaeo-ecology) and a section on global change effects on treelines, now and in the future. With more than 100 illustrations, many of them in colour, the book shows alpine treelines from around the globe and offers a wealth of scientific information in the form of diagrams and tables.
