This makes it difficult to conclude about the persisting disabling nature of ADHD symptoms.
Most of the known allopolyploids are established on even-ploidy levels with very few consistently odd-ploidy level taxa persisting in nature (e.g., pentaploid Rosa canina) [ 4, 5]).
Despite the historical importance of VACV, there are few data about the origins, natural reservoirs and mechanisms by which the virus persists in nature [12] [14].
Even among minerals with nominally the same composition, such as cinnabar – metacinnabar (both Hg1-xS), small differences in non-stoichiometry make aS0 a possible determinant of which phase is expected to form and persist in nature [17],[17].
A scientist at the University of Wisconsin known for his edgy influenza research, Yoshihiro Kawaoka, developed the H1N1 flu virus strain — also known as the swine flu — to evade immune protection, which humans tend to develop as a virus persists in nature.
B. mallei (BM), a host-adapted pathogen that does not normally persist in nature, causes glanders in horse.
However, widespread overall increases in NDVI during the study period suggest that plant production within the core of non-forested protected areas has become higher than it was in the surroundings of those areas in 1982, highlighting that whilst the distinctiveness of protected areas from their surroundings has persisted the nature of that difference has changed.
And evolution theory is to explain how such "antientropic" systems can appear and persist in nature.
Strong selection may persist in nature because overall fitness is not maximized by one component of fitness (Schluter et al. 1991), such as early fry survival.
Rift Valley fever, a febrile disease that affects livestock and humans, is transmitted by mosquitoes and caused by a virus (genus: Phlebovirus, family: Bunyaviridae) that can persist in nature in contaminated eggs.
