Revising the nitrogen cycle in the Peruvian oxygen minimum zone.
The oxygen minimum zone (OMZ) of the Eastern Tropical South Pacific (ETSP) is 1 of the 3 major regions in the world where oceanic nitrogen is lost in the pelagic realm. The recent identification of anammox, instead of denitrification, as the likely prevalent pathway for nitrogen loss in this OMZ raises strong questions about our understanding of nitrogen cycling and organic matter remineralizat...
متن کاملBiochemical identification of the leishmanias.
The taxonomy of the leishmanias is based on an intricate combination of features that includes “extrinsic” epidemiologic and biologic characters-such as the clinical picture of the infection in man (I, 21, experimental and natural development of the infection in sandflies, behavior of the organism in hamsters, growth rates of the organism in vitro, and morphology-supported by “intrinsic” charac...
متن کاملComparative Studies of Herpetomonads and Leishmanias
Nine strains of herpetomonads have been isolated in pure culture from eight varieties of insects, and three strains from two species of plants. Four of the cultures were derived from latex-feeding insects (Oncopeltus fasciatus, Oncopeltus sp. ?, Lygaeus kalmii) and three from latex plants (Asclepias syriaca, Asclepias nivea), two from mosquitoes (Culex pipiens and Anopheles quadrimaculatus), on...
متن کاملSex and the Single Gametophyte: Revising the Homosporous Vascular Plant Life Cycle in Light of Contemporary Research
Homosporous vascular plants are typically depicted as extreme inbreeders, with bisexual gametophytes that produce strictly homozygous sporophytes. This view is promulgated in textbook life cycles despite ample evidence that natural populations of most species regularly outcross. We review research on a variety of mechanisms, including genetic load, asynchronous production of eggs and sperm, and...
متن کاملFood Polymeric Packaging Life Cycle Assessment (LCA)
Food packaging is used to maintain the safety and quality of food during distribution and storage and to protect them from adverse internal and external conditions, such as water vapor, spoilage due to microorganisms, moisture, light, and dust. In this regard, lots of research studies have been done to increase shelf life, safety, and quality to create suitable physico...
