Temperature as an autoecological factor of chitinolytic microbial complex formation in soils

Biology Bulletin, 2007
The dynamics of carbon dioxide emission from soil was studied during chitinolytic succession induced by humidification and chitin introduction at different temperatures (5, 27, and 50 degrees C) using gas chromatography. The abundance and biomass of the chitinolytic bacterial and actinomycete complex in soil were evaluated by luminescent microscopy ...

Autoecological Approaches to Resolve Subjective Taxonomic Divisions within Arcellacea

Protist, 2014
Arcellacea (testate lobose amoebae) are important lacustrine environmental indicators that have been used in paleoclimatic reconstructions, assessing the effectiveness of mine tailings pond reclamation projects and for studying the effects of land use change in rural, industrial and urban settings.

Microdistribution of chironomids (Diptera: Chironomidae) in Alpine streams: an autoecological perspective

Hydrobiologia, 2005
Chironomid communities from three glacial and three non-glacial high mountain streams in three Alpine river basins were analyzed (Conca, Niscli, Cornisello, NE Italy, 46° N, 10° E). Eighteen sampling reaches belonging to five stream types (kryal, subkryal, glacio-rhithral, kreno-rhithral, outlet) were investigated.

Autoecological Studies on Mottra (Clinogyne dichotomy Salisb)

Journal of Agronomy and Crop Science, 1993
Abstract Clinogyne dichotoma, Salisb, belonging to the family Marantaceae, is a perennial crop with remarkable morphological characteristic. Present study on the anatomical features revealed their adaptability in waterlogged low‐lying marshy lands unsuitable for the cultivation of any other crop.

Autoecology of Sporobolus pyramidalis with emphasis on seed ecology [PDF]

S. pyramidalis is considered a major problem in Australia because it reduces the productivity of native and introduced pastures, and the profitability of industries dependent on grazing animals. It has low palatability and is difficult for stock to graze due to the fibrous nature of its leaf blades.

Autoecological and molecular approach to the species problem in the Euplotes vannus-crassus-minuta group (Ciliophora, Hypotrichida)

European Journal of Protistology, 1990
The long standing species problem in the Euplotes vannus-crassus-minuta group is addressed here by means of restriction enzyme rDNA maps and salinity and temperature tolerance tests performed on several strains of these morphospecies (i.e. morphologically identified species).

Biomathematical analysis of the autoecology of french diatoms

2018
Des indices biologiques végétaux DCE-compatibles (IBD, IBMR) sont actuellement utilisés en routine dans les réseaux de surveillance pour diagnostiquer l'Etat Ecologique des cours d'eau français. Ils permettent de porter un diagnostic de l'état écologique, ainsi que du degré général d'altération causé par les impacts anthropiques, mais restent néanmoins

Autoecology and morphological variability of Dinophysis sacculus (Dinophyceae: Dinophysiaceae) in a Mediterranean lagoon

Journal of the Marine Biological Association of the United Kingdom, 2001
Dinophysis sacculus (Dinophyceae) is a potential producer of diarrhoeic shellfish poisoning (DSP). Population dynamics of this dinoflagellate was followed in the Varano lagoon, south-east Italy, with the objective of determining the seasonal abundance of D. sacculus and the relationship to environmental factors.

Autoecological role of steviol glycosides in Stevia rebaudiana Bertoni

Stevia rebaudiana Bertoni is a shrub native to Paraguay now a commercial source of the natural and non-calorific sweeteners of the steviol glycoside class. In stevia leaves, stevioside and rebaudioside A are the major steviol glycosides (SGs), occurring at about 10 and 3-5% of the leaf dw respectively.
