Breeding rates of survivors were monitored in spring.
Second, the performance of DEMO control is limited by space restrictions for the implementation of components (optimization of the tritium breeding rate), by lifetime issues for the front-end parts (neutron and gamma radiation, erosion and deposition acting on all components) and by slow, weak and indirect action of the available actuators (plasma shaping, heating and fuelling).
Scientists say higher temperatures will lead to the feminisation of populations and affect breeding rates.
While these arguments have been based on correlations between the Australian environment and the breeding rates of the old endemic species, they have not considered the phylogenetic relationships of this group to other rodents outside Australia.
At very low densities, all females were able to breed but after the saturation of breeding territories the breeding rate dropped, and breeding of excess animals was suppressed (Point S in Figure 1A, parameterised for our empirical system in Figure 1B at ~3 females per enclosure).
This comparison showed that social mating system, number of helpers, clutch size, breeding success, rates of divorce, adult mortality, and incestuous pairing, rates of paternal care, and peak breeding synchrony are all very similar (Table 1).
Data collected would provide "essential scientific evidence of the unknown survival and breeding success rates of hedgehogs rehabilitated at the centre", the charity said.
We found that mortality did not differ among the densities, but the regulation of the breeding rate broke down: at double and triple densities all females were breeding, while at the low density the breeding rate was regulated as observed before.
Biologists swapped hunches and the breeding rate ticked up.
Towards the end of the plover breeding season, the rate of female divorce declines.
