It sees itself as an association of German-language owl experts. In addition to individuals, membership is open to groups, clubs, associations and institutions. The nature and species protection work of the OWG is based on the gathering, evaluation and dissemination of knowledge and experience regarding the biology and protection of owls. For each species of owl occurring in Germany there is a species specialist and for each federal state there is a state representative. Every year, the OWG organises a meeting at different locations, mostly in Germany , in cooperation with local associations or groups. In December , about 30 people met in Soest to establish a little owl working group under the auspices of the Westphalian Ornithological Society and the Society of Rhineland Ornithologists. In , the two working groups were still holding separate meetings. At the end of , both working groups were merged to form the Working Group for the Protection of Endangered Owls, abbreviated as Owls Working Group. A first position paper, published in , stated that the goal of the Owls Working Group was to carry out owl protection work on a scientific basis. In the OWG published standard methods for the recording of little owl populations.

Euglena is a genus of single cell flagellate eukaryotes. It is the best known and most widely studied member of the class Euglenoidea , a diverse group containing some 54 genera and at least species. They are often abundant in quiet inland waters where they may bloom in numbers sufficient to color the surface of ponds and ditches green E. The species Euglena gracilis has been used extensively in the laboratory as a model organism. Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy , like plants. However, they can also take nourishment heterotrophically , like animals.

A new way of understanding the activity is born. In the late 60s, the headquarters of the company includes a training school and a laboratory that experiments with products and materials. The company has branches in the major cities of Spain, serving prestigious clients who are slowly beginning to outsource cleaning. The first expansion occurs with the foundation of Prosesa, the current EULEN Security — initiating activities of private security using as an advantage the legal regulation that compels banks and savings banks. DEMASA is founded as a company, dedicated to the manufacture, import and distribution of machinery and chemicals used for cleaning. Activities such as maintenance of facilities, environment, energy control, restoration of facades and monuments, and works commence. The owl is embraced as a symbol of quality in the logo. Alvarez advances a concept of outsourcing as a set of services that allows a company to focus on their core business and not to worry about maintenance and conservation tasks.

Wikimedia Commons. Dictionary of Scientific Biography. Different species of owls produce different sounds; this distribution of calls aids owls in finding mates or announcing their presence to potential competitors, and also aids ornithologists and birders in locating these birds and distinguishing species. Since owls can be found in nearly all parts of the world and across a multitude of ecosystems, their hunting skills and characteristics vary slightly from species to species, though most characteristics are shared among all species. Ovid , too, constantly speaks of this bird's presence as an evil omen; and indeed the same notions respecting it may be found among the writings of most of the ancient poets.
