Some are returned to the wild in sex ratios that hinder population growth (and threaten their genetic viability, say some).
According to marine biologist and shark expert Mauricio Hoyos, this is an issue that deserves to be addressed because it could hinder population growth and eventually cause decimation of this particular group.
In species whose mating system is characterized by sexual conflict, male skewed sex ratios may even hinder population growth rate (Rankin and Kokko 2007), and this would reduce the likelihood of establishing a self-sustaining population during reintroduction.
Incorporating mate choice into captive breeding recommendations presents a huge challenge, both in terms of the logistics of offering mate choice in captive settings and in implementing choice in a way that augments rather than hinders population management goals (Asa et al. 2011; see Fig. 1).
One of the major disadvantages of the gravid traps, however, is the use of cumbersome, infusion-based attractants whose offensive smell hinders population monitoring in human dwellings.
Climate-driven range reduction can have significant genetic and evolutionary consequences for surviving populations by decreasing genetic diversity and hindering a population's ability to adapt to future ecological disturbances (for example, [ 9]).
The nuisance and damages caused by road failures in Phewa watershed are a clear hinder to population mobility and development which are the result of the lack of proper initial road design and maintenance programs.
A lack of effective molecular markers has hindered phylogenetic and population genetic studies concerning copepods.
Frequent fighting since December 2006 has interrupted the supply of food to the population, hindered access to clean drinking water, destroyed health service infrastructure, precipitated widespread looting of medicine and material, and limited new nutritional interventions from being developed, placing thousands of children in the area at risk.
How can a cooperative (altruistic) act spread in a population where originally only defectors existed? 2. How is the spread of cheaters (agents that enjoy the benefit of cooperation, but don't invest into it) hindered in a population of cooperative individuals?
