4 sie 2021 · These results help explain why some species seem to care more about inbreeding than others: inbreeding avoidance through mate choice only evolves when there is both a risk of inbreeding depression and related sexual partners frequently encounter each other.
1 maj 2002 · Data from bird and mammal populations suggest that inbreeding depression often significantly affects birth weight, survival, reproduction and resistance to disease, predation and environmental stress.
3 maj 2021 · Theoretical and empirical work highlights a wide range of factors that are hypothesized to influence inbreeding avoidance in animals (Box figure).
26 lut 2015 · Natural populations of many species are faced with an increasing number of pressures from human-driven environmental changes, such as habitat degradation and fragmentation. These pressures can lead to local reductions in population size, and increases in the isolation of populations.
20 maj 2021 · The detrimental effects of inbreeding on a broad range of traits, individual fitness and population viability have now been recognised across the animal and plant kingdoms 1,2,3,4,5,6,7,8,9.
24 maj 2021 · We find consistent negative effects of offspring inbreeding on survival, and reveal differences in dam and sire responses to first-generation versus multiple generations of captive breeding.
