Foster's rule, the island rule, or the island effect states that members of a species get smaller or bigger depending on the resources available in the environment. [ 28 ] [ 29 ] [ 30 ] The rule was first stated by J. Bristol Foster in 1964 in the journal Nature , in an article titled "The evolution of mammals on islands".
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end.
LINE elements propagate by a so-called target primed reverse transcription mechanism (TPRT), which was first described for the R2 element from the silkworm Bombyx mori. ORF2 (and ORF1 when present) proteins primarily associate in cis with their encoding mRNA , forming a ribonucleoprotein (RNP) complex, likely composed of two ORF2s and an ...
Ecological succession is the process of change in the species that make up an ecological community over time. The process of succession occurs either after the initial colonization of a newly created habitat, or after a disturbance substantially alters a pre-existing habitat. [1]
Biological rules describe patterns of variation within and across species most often in regard to size. While they are described as rules there are often many exceptions to them. While they are described as rules there are often many exceptions to them.
President Donald Trump revealed early Friday that both he and the first lady have tested positive for the COVID-19. While the full extent of the president's condition is not known, a White House ...
Unlike the “heir apparent,” whose position as second in line is absolute, the heir presumptive’s position is subject to displacement in the event a male heir is subsequently born, which, as ...
An order, line or right of succession is the line of individuals necessitated to hold a high office when it becomes vacated, such as head of state or an honour such as a title of nobility. [1] This sequence may be regulated through descent or by statute. [1] Hereditary government form differs from elected government.
