Complex Niches Favour Rational Species

Journal of Theoretical Biology, 1996
On the whole living things evolve from simpler to more complex forms, though not undirectionally. The evolution of more complex species makes the environment more complex and also makes the evolution of even more complex species possible and more selectable.

Streptomyces species producing the streptovaricin complex

Folia Microbiologica, 1991
Morphological, cultural and physiological-biochemical properties of Streptomyces sp. strain 1000 and its antibiotic production were investigated. Antibiotics 1011 (identical with the streptovaricin complex) and 1012 (with antibacterial action) were isolated from the cultural broth of this strain. The overproducing natural variant 1011 was isolated from

The Hirudo medicinalis species complex

Naturwissenschaften, 2012
Recently, Hildebrandt and Lemke (Naturwissenschaften 98:995-1008, 2011) argued that the taxonomic status of the three European medicinal leeches, Hirudo medicinalis Linnaeus 1758, Hirudo verbana Carena 1820, and Hirudo orientalis Utevsky and Trontelj (Parasitol Res 98:61-66, 2005) is "questionable" since "all three species interbreed in the laboratory".

Synthesis of complex phospholipid species

Proceedings of 2022 AOCS Annual Meeting & Expo, 2022
Phospholipids are essential for the preservation of life on the planet and carry numerous critical roles and functions, including being the main constituents of the cell-membranes in both eukaryotic and prokaryotic cells, providing (more bioavailable) energy, and maintaining chemical and electrical processes in the body.

Sterols as Complex-forming Species

Russian Chemical Reviews, 1986
The formation of complexes of sterols with different compounds determines the biological properties of both sterols and various natural substances such as saponins and polyene antibiotics. Complex formation by sterols with phospholipids, steroid saponins, and polyene antibiotics is determined by the same characteristic features of the structure of the ...
