TL;DR: In this article, a successful laser oscillation of various pyrromethene dyes doped in a modified acrylic plastic has been achieved, with only a 34% loss in the available output energy.

TL;DR: It is imperative that appropriate counter measures such as assisted reproductive technologies (ART) be utilized to ensure early pregnancy in captive animals for their preservation and to ensure increased genetic diversity of the captive populations.

TL;DR: The data suggests that the development of reproductive pathology and ovarian inactivity in white rhinoceros is an age-related consequence of long non-reproductive periods and can be prevented with the achievement of at least one pregnancy.

TL;DR: Although many of these bulls could serve as semen donors for natural mating or artificial insemination, the inconsistent production of good-quality ejaculates raises questions as to the reliability of these individuals to participate in breeding programs.

TL;DR: The results indicate that low rate of reproduction in captivity can be attributed to reduced male reproductive fitness and changes in management of white rhinoceroses may positively affect male reproductive function.
