Overfishing in general, and particularly of spawning aggregations that occur when certain species of reef fish gather in one place in great numbers to reproduce, may be the culprit, says Yvonne Sadovy, a biologist at the University of Hong Kong who wrote the report along with scientists from Australia, Hong Kong, Palau and the United States.
For such islands, the evolutionary selection forces that are at play can be very different than those on the mainland, and evolutionary strategies that were necessary on the mainland to avoid being eaten and to find enough food to reproduce may then become obsolete.
A 2008 study suggests the abilities of female penguins to reproduce may be negatively affected by climate- and fishing-induced reductions in krill density.
In an asexual multicellular organism, rogue cells which retain the ability to reproduce may take over and reduce the organism to a mass of undifferentiated cells.
Furthermore, it is likely that with uterine ageing (attributed to previous pregnancies and extended interval between pregnancies), the physiological capacity to reproduce may decline.
It has not been filed with FINRA, may not be reproduced and may not be shown to, quoted to or used with members of the public.
Put differently, castrating the host after it has reproduced once may be less costly to the parasite than doing so immediately after penetration, and may allow the parasite to focus on replicating itself to achieve a competitive edge [ 47].
If your questions are systematically evaded or the results still can't be reproduced, you may have a problem.
The fold-change threshold of 1.5 was chosen as a compromise between a complete view of the transcriptional response and omitting responses that are not strong enough to be reproduced or may be the result of statistical noise.
Asexually reproduced larvae may travel long distances, but this probably does not happen very often in corals [12].
