Sentence examples for under breeding from inspiring English sources
The initial experiment tested birds under breeding season conditions: the zebra finch aviary was kept under a 12 12 light-dark cycle and the canary aviary was kept under a natural light-dark cycle corresponding to the local photo-period.
However, a significant sex difference was found between ISO males and females recorded under breeding conditions, suggesting that female canaries may be more sensitive to isolation than male canaries and zebra finches of either sex, or that the hormonal state of males during the spring overrides an isolation stress effect that only occurs in females at this time of year.
Specific genes that encode neurotrophins known to promote neuronal migration, recruitment, and survival, including brain-derived neurotrophic factor (BDNF) and insulin-like growth factor 1 were differentially regulated in HVC under breeding conditions in both studies [ 40].
In both studies, genes that promoted proliferation, angiogenesis, and neurite extension were up-regulated, whereas genes that support programmed cell death were down-regulated in HVC under breeding conditions [ 40].
In order to evaluate whether or not this was the case, the absolute amplitude of responses to the preferred frequency at each site (the frequency that evoked the highest response amplitude) was compared between the groups that differed the most in their tuning: the CROSS and ISO canary females tested under breeding conditions.
The Lde and LT breeds, which have distinct muscle phenotypes, were domesticated under different breeding goals in Europe and Asia [ 2, 5, 11].
Under this scenario, in replicated commercial populations that have been under similar breeding regime inter- and intrapopulations (e.g., egg layers vs. broilers), an overlapping cluster of differentiated alleles may reflect parallel divergence of beneficial allele.
Performing this technique under "speed breeding" conditions (plants grown at a density of 600 plants / m2, under controlled temperature and constant light) allows the selection based on the desired root traits of up to 5 consecutive generations within 12 months.
Under a breeding program run by the park, tortoise eggs — which, along with the young are endangered by nonnative mammals — are incubated and the hatchlings raised at the Charles Darwin Research Station in the town of Puerto Ayora before being "repatriated" at age 5 to their home islands.
A simple analytical model is also developed and presented in order to investigate the conditions under which breeding in HSR is possible, which supports the ANET simulation findings.
Limitations and capabilities of the model are shown by means of zero-dimensional simulation and sensitivity analysis under HCLL breeding unit conditions.
