The striking convergences in morphology, behaviour and physiology existing between various species of sea birds are discussed, both on the basis of personal observations, mostly carried out in the Antartic and Sub Antartic zones, and from data
outdoor climate. PhS defines the kind and intensity of physiological processes during adaptation to ambient thermal conditions. - (BJ)
, they did not include information of direct, physiological relationships between man and his surroundings. This paper proposes a new approach based on the human heat balance analysis. Biothermal indices like subjective temperature (STI), haet load (HL
) and physiological strain (PhS) are derived from man-environment heat exchange model MENEX―2002. STI evaluates the thermal sensations in man outdoors during light physical activity. HL assesses the loading of the thermoregulatory system in man in a fluctuating
Tree physiology and yield improvement. A compendium of papers given at a meeting held near Edinburgh in July 1975
essai d'explication physiologique des différences constatées dans les productions de bois. Ce problème est naturellement très complexe. Il est pourtant remarquablement bien traité dans le livre, surtout dans les chapitres qui concernent les adaptations à
Development of a physiologically mechanistic model for use at the alpine treeline ecotone
The purpose of this research is to evaluate the relative importance of selected processes (snow redistribution and winter dessication) important at the alpine treeline ecotone (ATE) using an existing physiologically mechanistic model, FOREST-BGC
Physiological significance of low atmospheric CO2 for plant-climate interactions
This paper reviews the scope of research addressing the consequences of low atmospheric CO2 for plant and ecosystem processes and highlights why consideration of the physiological effects of low atmospheric CO2 on plant function is recommended
New climatological and physiological model of the human heat balance outdoor (MENEX) and its applications in bioclimatological studies in different scales
Temperature response of soil respiration depends on the sensitivity and adaptability of soil respiration (SR) for the variation of soil temperature, which will directly influence the terrestrial carbon cycling and extent prediction of global warming
of the differences of plant physiology and environment conditions, temperature sensitivity of soil respiration (Q10) varied among vegetation types. The seasonal variation of Q10 was primarily driven by soil temperature while soil moisture had little influence
temperature. Under global warming, the population expansion and the domain enlargement of Betula ermanii led to a treeline shift. The population has continued to vary its physiological traits to adapt to air temperature change.
This article discusses recent developments in biogeography and discusses some attempts at synthesis. The main body of the article, however, is devoted to the conceptions of ranges in terms of physiological responses to environmental variation
Influence on ecological heat and water regimes and physiologic processes (water regime, photosynthetis, respiration) in Carex physodes Bieb. and Poa bulbosa L. var vivipara Koeler). Carex physodes that is the dominant of herbage in the groves
of Haloxylon persicum weakens its positions in 3-5 years in presence of Trotula desertorum. Spread of the moss results in decrease of Carex physodes number, reduction of its productivity and intensification of physiological processes. Poa bulbosa is more
Weathered regolith containing halloysite and kaolinite is ingested by cattle on the Venezuelan paramo in possible response to physiologic need. - (DWG)
The landscape ecology existing in geography since the time of A. von HUMBOLDT, was named landscape physiology . Since C. TROLL (1939) obtained the name landscape ecology . From the point of view of geography it is a complex research aiming
by the physiological response of the cyanobacteria to changes in hydro-environmental conditions. The role of modelling in management is considered and an alternative schematic model to calculate the cyanobacterial light-budget is presented. Such a model could form
the topoclimatological point of view and informs on the physiological reactions of the human body in different local climatic conditions. In the author's opinion the classification could also be adopted for other types of Polish landscape.―(D'après l'A.).
This paper briefly reviews and tentatively discusses 1) former climatic changes and their impact on forests, 2) the impact of climatic warming on the genetic constitution of forest trees, their physiological processes, and the possible alteration
