A biocoenosis (biocoenose, biocenose, biotic community, biological community, ecological community), coined by Karl Möbius in 1877, describes the interacting organisms living together in a habitat (biotope). This term is rarely used in English, as this concept has not been popularized in Anglophone countries. Instead, English-speaking scientists usually think about ecosystems or communities.
Descriptors in an ecosystem are:
The geographical extent of a biocenose is limited by the requirement of a more or less uniform species composition.
An ecosystem, as originally defined by Tansley (1935), is a biotic community (or biocoenosis) along with its physical environment (or biotope). In ecological studies, biocoenosis is the emphasis on relationships between species in an area. These relationships are an additional consideration to the interaction of each species with the its physical environment.
Biotic communities vary in size, and larger ones may contain smaller ones. Species interactions are evident in food or feeding relationships. A method of delineating biotic communities is to map the food network to identify which species feed upon which others and then determine the system boundary as the one that can be drawn through the fewest consumption links relative to the number of species within the boundary.
Benedictus van Haeften (1588 – 31 July 1648) Provost of Affligem Abbey and famous writer of religious works.
Haeften commissioned Rubens and De Crayer to decorate the church and the monastery in Affligem.
Van Haeften was a Benedictine writer, provost of the Monastery of Afflighem, Belgium. He was born in Utrecht, 1588, and died 31 July 1648, at Spa, Belgium, where he had gone to recover his health.
After studying philosophy and theology at the Catholic University of Leuven, he entered the Benedictine Abbey of Afflighem in 1609, took solemn vows on 14 May 1611, and was ordained priest in 1613. He then returned to Leuven to continue his theological studies, but was recalled to his monastery when he was about to receive the licentiate in theology.
In 1616 he became prior, and in 1618 Matthias Hovius, Archbishop of Mechlin, who was at the same time Abbot of Afflighem, appointed him provost of his monastery. Afflighem at the time belonged to the Bursfeld Union, and under the prudent direction of van Haeften was in a flourishing condition.
