Microbial growth within the water-saturated subsurface environment was investigated by exposing sandy sediments to groundwater for 12 weeks at a depth of 10 or 20 m in a stainless-steel groundwater well. Washing and heating the sediment to 600 degrees C (removal of organic carbon) prior to the exposure did not prevent the natural microbial community from colonizing the sterilized sediment sampl...
The aim of this study was to examine the symbiosis relationshipbetween some arbuscular mycorrhizal fungi (AMF) and Salsola laricina (Chenopodiaceae), a non-mycotrophic plant speciesand its effect on improving plant growth parameters. Initially, the development of AMF density was monitored through two parameters including evaluation of mycorrhizal colonization of plant roots and density measurem...
Ontogenetic conflict arises when optima for alleles governing fitness variation differ between juveniles and adults or between adult sexes. Loci that govern development of alternative phenotypes in the sexes, hereafter termed morph-determining loci, mediate development through the endocrine system. Morphotypic selection is defined to be multivariate selection favoring discrete alternative morph...
Testis maturation, germ cell development and function of sperm, are related to lipid composition. Phosphatidylcholines (PCs) play a key role in the structure and function of testes. As well, increases of polyunsaturated fatty acids (PUFA) and highly unsaturated fatty acids (HUFA), especially arachidonic acid (ARA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are essential for ma...
Marshallagia lichtenfelsi sp. n. is a dimorphic ostertagiine nematode occurring in the abomasum of mountain goats, Oreamnos americanus, from the Western Cordillera of North America. Major and minor morphotype males and females are characterized and distinguished relative to the morphologically similar Marshallagia marshalli/Marshallagia occidentalis from North America and Marshallagia dentispic...
