Evolutionary tradeoffs can be present in a form called life history tradeoffs, which can be defined as the decrease in fitness (essentially, lifetime reproductive success) caused by one life history trait as a result of the increase in fitness caused by a different life history trait. [5]
Chaos is a genus of single-celled amoeboid organisms in the family Amoebidae.The largest and most-known species, the so-called "giant amoeba" (Chaos carolinensis), can reach lengths up to 5 mm, although most specimens fall between 1 and 3 mm. [3] [4] [5]
Gromia sphaerica is a large spherical testate amoeba, a single-celled eukaryotic organism and the largest of its genus, Gromia. The genus itself contains about 13 known species, 3 of which were discovered as late as 2005. [1] It was discovered in 2000, along the Oman margin of the Arabian Sea, at depths around 1,163 to 1,194 meters (3,816 to ...
Pelomyxa is a genus of giant flagellar amoebae, usually 500–800 μm but occasionally up to 5 mm in length, found in anaerobic or microaerobic bottom sediments of stagnant freshwater ponds or slow-moving streams. [1] The genus was created by R. Greeff, in 1874, with Pelomyxa palustris as its type species. [2]
The concepts of quantity or quality offspring are sometimes referred to as "cheap" or "expensive", a comment on the expendable nature of the offspring and parental commitment made. [1] The stability of the environment can predict if many expendable offspring are made or if fewer offspring of higher quality would lead to higher reproductive success.
Mask up, Los Angeles-area music geeks (and record-shopping) tourists: Amoeba Music is about to be back in business at its long-promised new location, but don’t expect to be able to just walk in ...
This social cycle results in a differentiation between cells: ~20% are sacrificed to form a structural stalk, [10] some transform into sentinel cells with immune like and detoxifying functions, [4] and the rest of the aggregated amoeba form a ball of spores located in protective fruiting body. [8]
The club’s net spend on player transfers hit a record £1.19 billion ($1.52 billion) between 2014 and 2023, according to the CIES Football Observatory—quadruple that of successful rivals ...
