Similarly, while reducing adult vector emergence and abundance, source reduction of larval habitats may prolong the cycle duration by extending delays in locating oviposition sites.
Similarly, the New Zealand rock lobster fishery was on a path of declining abundance before a reduction in effort and season length substantially increased abundance, catch rates, and profitability [8].
Considering the hunting statistics as a proxy for wolf abundance, the largest reduction appears to have occurred prior the 20th century.
470 unique genes were found to have differential expression in one or more time point, and these genes did show a significant GO term abundance for oxidation reduction when analyzed through AgriGO (p = 0.00044, Fig. 3).
This attenuation was associated with a decrease in the number of α-SMA + fibroblasts as well as a considerable improvement in cross-linked fibrillar collagen abundance and a reduction in TGF-β signalling (Barry-Hamilton et al., 2010).
Our data show that experimentally reducing parasite abundance leads to a reduction in nestling body mass, tarsus length, and outermost primary feather length.
Metaldehyde, niclosamide and saponin reduced the abundance (average 51% reduction), biomass-density (average 63% reduction) and species richness (average 38% reduction) of flies emerging from the snail cadavers.
"The proposed reduction in abundance could have happened at any point in [recent] evolutionary time," says Per Palsbøll, a whale population geneticist at the University of California, Berkeley.
This initial reduction in abundance combined with the further reduced proportion of juveniles may have longer lasting effects even as the forest regenerates.
The reduction in abundance of one species was greater in aggregated retention than in control stands and for three other species this reduction was greater in the structurally more simple forest.
