Physiological Responses to Nutrient Limitation

physiological responses of fennel (foeniculum vulgare l.) to water limitation

two field experiments were conducted at the research farm of the faculty of agriculture, university of tabriz, iran during 2009-2010 and 2010-2011, to evaluate the response of fennel (foeniculum vulgare l.) landraces to limited irrigation. experiments were arranged as split plot based on randomized complete block design in three replications with irrigation treatments (irrigation after 60, 90, ...

Eco-physiological adaptation shapes the response of calcifying algae to nutrient limitation

The steady increase in global ocean temperature will most likely lead to nutrient limitation in the photic zone. This will impact the physiology of marine algae, including the globally important calcifying coccolithophores. Understanding their adaptive patterns is essential for modelling carbon production in a low-nutrient ocean. We investigated the physiology of Helicosphaera carteri, a repres...

The physiological bases of nutrient responses during lactation.

The lactating dairy cow responds to dietary changes according to the nutrients provided and her propensity to produce milk. The allocation of nutrient use to milk production or body gain is generally termed ‘partition’ and has been shown to be a function of both the animal and its diet. As feed intake is increased, the lactating cow responds with progressively smaller increments of increased mi...
