Loss of pond habitat decreased population growth rate, with greater decreases associated with loss of permanent and semi-permanent habitat.
Since the authors had eliminated these variables, there was one remaining possibility: the authors attributed this decreased population growth to poaching.
Nevertheless, we found that changes in reproductive rates linked to increases in human exposure frequency have the potential to decrease population growth rates by as much as 11% (Figure 4).
At all concentrations tested, DDD00015314 caused decreased population growth (Fig. 7A) and accumulation in G1/G0 (Fig. 7B) equivalent to that induced by 100 μM 8-pCPT-cAMP.
Gleason and Nacci (2001) provided an example of the use of a matrix model for the fathead minnow to relate a decreased population growth rate in fish exposed to estradiol to vitellogenin induction (in males).
Russia's population declined by nearly 3.4 million over the past decade, according to census figures released Monday, adding to fears that an aging and decreasing population will sap economic growth.
Significantly higher QST values than GST values can be interpreted as diversifying selection for local adaptation, whereas stabilizing selection is expected to decrease population differentiation in growth rate leading to lower QST than GST (Spitze 1993).
For instance, we observed a decreased pathogen growth up to 36% following pre-infestation by aphids, and a decreased aphid population growth up to 40% following pathogen pre-infestation.
Blocking access to the tributaries decreased overall population growth rates and increased the likelihood of network-wide extinction.
A version of the Fisher-Kolmogorov equation was used to quantify the simultaneous effects of TGF-beta to increase the tendency of individual cells and cell clusters to move randomly and to decrease overall population growth.
