  • In the thermodynamic theory of aquatic ecosystems the non-linear relations between rates and affinities of biological processes, such as primary production, respiration, grazing etc. can be determined using an optimun principle. Especially
  • , the dependence of primary production rate on light intensity, temperature, dissolved inorganic matter and on the biomass can be derived. (HL).

  • Characteristics of carbon flux in two biologically crusted soils in the Gurbantunggut Desert, Northwestern China
  • carbon flux in biologically crusted soils after 0, 2, 5, and 15 mm precipitation treatments. Carbon flux between crusted soil and bareland had no significant difference. The average carbon flux rate and total carbon production increased exponentially
  • with the precipitation amount. This study indicates that biological soil crusts do not increase the respiration of soil, but increases the temperature dependence of soil carbon flux because of the higher microbial biomass than bareland.
  • Karst is a biological product
  • Biological oceanographic processes.
  • processus chimiques, la production primaire et secondaire et les divers cycles biologiques du domaine pélagique. De même, à partir de la répartition de la vie benthique, ils en arrivent aux processus chimiques et à la production du benthos. Le dernier

  • Au moment où est lancé le programme Biomass dans l'océan Austral, l'A. souligne que la vie n'y foisonne pas autant qu'on l'a cru, car le manque de lumière dû à la latitude et à l'agitation de la surface est un facteur limitatif de la production
  • Use of satellite images in mapping of biological diversity in Senegal
  • The aim of the project is to develop a method for mapping and monitoring of biological diversity in the Sahel zone. Sahel is undergoing marked environmental changes, affecting not only human populations but also ecological communities. These ongoing
  • processes have biological implications on both national and international levels. The Sahelian biotopes hold a number of endemic biological assets and constitute the main wintering ground for a significant number of Palearctic migratory bird species.

  • According to Hainan Island's biological characteristics, and existing structure of productivity of tropical crops and local climatic conditions, this paper carries on regional division of tropical crops by fuzzy mathematics. Based on calculation
  • of basic parameters for the formation of production, near-term optimum models of tropical crops structure of each region was established by means of multi-objective programming.
  • Palaeoecological evidence for environmental change during the last 200 years. I. Biological data
  • This paper reviews the role of biological data for assessing ecosystem change during the last 200 years, with examples from North America and Europe where most of this research, has to date, been concentrated.
  • There are considered the floodplain geocomplexes in the middle and lower reaches of the Protva river and their peculiarities related to the influence of differences in the history of development and hydrological regime of the river. The biological
