Oxidative stress, generated by excessive reactive oxygen species (ROS) or decreased
antioxidant defenses (and possibly both), is associated with male infertility. Oxidative stress …

There is a remarkable diversity in the animal kingdom regarding mechanisms underlying the
production, maturation, structure, and function of sperm cells. Spermatology studies …

In populations or species with low fitness (high genetic load), a new management strategy
called genetic rescue has been advocated to help avoid extinction. In this strategy, unrelated …

Inbreeding depression is known to affect quantitative traits such as male fertility and sperm
quality, but the genetic basis for these associations is poorly understood. Most studies have …

Populations forced through bottlenecks typically lose genetic variation and exhibit
inbreeding depression.'Genetic rescue'techniques that introduce individuals from outbred …

Allee effects reduce the viability of small populations in many different ways, which act
synergistically to lead populations towards extinction vortexes. The Sierra Morena wolf …

Inbreeding causes increases in homozygosity and is commonly associated with reductions
in fertility and embryogenesis. Although the mechanisms underlying such effects are …

The gray wolf (Canis lupus) population on the Iberian Peninsula was the largest in western
and central Europe during most of the 20th century, with its size apparently never under a …

Native only to the California Channel Islands, the island fox is the smallest canid in North
America. Populations on four of the islands were threatened to extinction in the 1990s due to …

Genome resource banks (GRBs) have the potential to preserve the genetic diversity of a
species over time, yet they are rarely utilized as effective components of conservation …
