It must be noted, however, that the species differences
in the SCN do not segregate in a clear fashion with respect to the diurnal or nocturnal habits of the species studied so far.
Many QTL may have gone undetected in this analysis because environmental variation that is large relative to the species difference
hampers the ability to detect QTL of small effect.
in response to peroxisome proliferators correlate in vitro with induction of DNA synthesis rather than suppression of apoptosis.
The observed species differences
were attributed to differences in first pass metabolism rather than species differences
Hybridization between these 2 species, which is the result of secondary contact and apparently does not occur where the 2 species occur in sympatry in their native range (Ross & Shoemaker 2005), provides an excellent opportunity for evolutionary genetic studies aimed at understanding the genetic architecture of species differences
, the consequences and fate of a hybrid zone formed in recent time, as well as the extrinsic and intrinsic factors affecting hybrid fitness.
Our findings support species differences
in habitat tolerance, specifically with respect to amount of cover, as a major influence on habitat use by meadow and prairie voles, with agonistic interactions reinforcing these tolerances.
It would he interesting to compare crawling and burrowing within the same species to determine whether these different strategies to increase velocity depend on locomotory mode rather than simply reflecting species differences
2010), indicating that selection plays an important role in shaping species differences
Scientists from the US and Canada describe the impact of methanol on the environment; human toxicity, including exposure, metabolism, in utero exposure, controlled human studies, and management of methanol poisoning; animal and aquatic toxicity, including acute toxicity, irritation, sensitization, and repeat exposures; the developmental and reproductive toxicology of methanol and the pathogenesis of methanol-induced birth defects; differences between PBPK (physiologically based pharmacokinetic) models of methanol disposition in mice and humans; oxidative stress and species differences
in the metabolism, developmental toxicity, and carcinogenic potential of methanol and ethanol; and methanol and cancer.
And when you look at the intersection of those two things they give us a really good set of candidate regions for what might be causing species differences
," he said.
On the other side of the spectrum, the mitochondrial sequence data can help clarify whether the observed variation among samples, such as the color morphs in Harmathoe imbricata mentioned above, reflects species differences
or intraspecific variation.
The authors conclude that blood vessel development is a target for environmental chemicals acting as putative vascular disruptor compounds and suggest potential species differences
in sensitive vascular developmental pathways.
The newer metric NODF is based on two matrix properties, decreasing fill and paired overlap, and enables to differentiate between a part of the overall nestedness introduced by species differences
(NODFspp) corresponding to species occupancy and site (months) differences (NODFm) in species composition (Almeida-Neto et al.
Intact platelets do not accumulate arachidonate following DHLA administration, and species differences
occur in the capacity of animals to metabolize DHLA to arachidonic acid (AA).
Differences observed by molecular typing methods do not correspond to those observed in biochemical tests and morphology; these methods not only identify species differences
in this genus, but also identify differences within the same species.
