Edgardo Griffith, a herpetologist who worked on the BBC documentary and rescued the last of the El Vallé frogs, is the director of the El Vallé Amphibian Conservation Center in western Panama, which maintains a breeding population of seven male and three female golden frogs.
A male sea otter is most likely to mate if he maintains a breeding territory in an area that is also favored by females.
It maintains a breeding territory of 2 5 ha and is also territorial on the wintering grounds, defending an area of about 3 ha.
However, maintaining a breeding colony of Tln2cd/cd mice is challenging for unexplained reasons, while Tln2ko/ko mice in which the first codon exon has been deleted [12], and continue to express reduced levels of talin2 in non-muscle tissues, show no such problems.
This was not easy, particularly where the resources available to maintain a nonproductive breeding stock were limited.
Minimum approach distance guidelines are common tools to maintain a buffer between breeding seabirds and human activity, with the goal of mitigating potentially harmful impacts from these interactions.
Consequently, we suggest that forest managers consider prescriptions that result in a broad spatial distribution of heterogeneous habitat structural conditions (e.g., variation in understory cover and composition), irrespective of landscape context, to maintain a diverse avian breeding assemblage on landscapes in this region.
"Look at the floor drain — it's the highest point on the floor," Caitlin Johnson, a living systems staff member, said as she stood in the crowded space where the department maintained a bookcaselike breeding module for zebra fish, and other assorted equipment.
