In this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct.
High levels of ammonia resulting from the breakdown of NPN can disrupt rumen pH balance and microbial activity, leading to conditions such as rumen acidosis and ammonia toxicity. [12] Furthermore, excessive excretion of nitrogen in urine and feces from animals consuming diets high in NPN can contribute to nitrogen pollution in the environment.
Seabird guano is the fecal excrement from marine birds and has an organic matter content greater than 40%, and is a source of nitrogen (N) and available phosphate (P 2 O 5). [2] Unlike most mammals, birds do not excrete urea , but uric acid , so that the amount of nitrogen per volume is much higher than in other animal excrement.
The total nitrogen content depends largely on the soil organic matter content, which in turn depends on texture, climate, vegetation, topography, age and soil management. [40] Soil nitrogen typically decreases by 0.2 to 0.3% for every temperature increase by 10 °C. Usually, grassland soils contain more soil nitrogen than forest soils, because ...
Faba, an earlier synonym, is from a Latin plant name. [9] [65] [66] 780 genera, scattered worldwide [9] [67] Also known as legumes. Trees, shrubs, vines and herbaceous plants. The roots are generally nitrogen-fixing. Staple foods include soybeans, peanuts, peas and various beans. Some species provide valuable gums, soaps and perfumes. [9] [19 ...
The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.
The word is a contraction of the Greek words νἰτρον (nitron) meaning "saltpetre" and φίλος (philos) meaning "friendly". [1] Nitrophily is traditionally expressed as a score between 1 (not nitrophilous at all) and 10 (extremely nitrophilous) according to the Ellenberg N Index. [2]
The Chesapeake Bay experiences seasonal hypoxia due to high nitrogen levels. [32] These nitrogen levels are caused by urbanization, there are multiple factories that pollute the atmosphere with nitrogen, and agriculture, the opposite side of the bay is used for poultry farming, which produces a lot of manure that ends up running off into the ...
