Future Challenges and Opportunities for the Viability of Animal Populations in Zoos and Aquariums

Zoo Biology, EarlyView.
ABSTRACT Maintaining sustainable animal populations is fundamental to zoo and aquarium missions in education, visitor engagement, entertainment, scientific advancement, public health and wellbeing, advocacy, and conservation impact. Yet, sustaining viable populations remains a persistent challenge.

Release from natural enemies mitigates inbreeding depression in native and invasive Silene latifolia populations

Ecology and Evolution, 2019
Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success of plant invasions if introduced populations ...

Quantifying inbreeding avoidance through extra-pair reproduction [PDF]

, 2015
Extra-pair reproduction is widely hypothesized to allow females to avoid inbreeding with related socially paired males. Consequently, numerous field studies have tested the key predictions that extra-pair offspring are less inbred than females ...

A note on inbreeding in dairy cattle breeding [PDF]

, 2005
Starting from the study at the beginning of the East German "Heterosisfeldversuch", where PANICKE et al. (1975) considered the possibilities of a targeted use of inbreeding and heterotic effects, we show and discuss results of inbreeding studies in the ...

Baseline Cortisol and Behavioral Phenotype Are Linked to Context‐Dependent Spatial Cognition and Space Use in Giant Pandas

Integrative Zoology, EarlyView.
Baseline cortisol and repeatable behavioral phenotypes were associated with context‐dependent spatial cognition in giant pandas. Individuals differed in spatial search performance under stable and changing resource conditions. Exploratory GPS analyses revealed directionally consistent but non‐significant patterns of space use in novel environments ...

On the extremum principle of natural with inbreeding

, 1997
The extremum principle in the genetical theory of natural selection has been discussed when the population undergoes inbreeding at a constant value of the inbreeding coefficient with constant fitness of the three genotypes possible with two alleles at a ...

Captive Breeding of the Chinese Alligator Reduces Inbreeding but Increases Genetic Load

Integrative Zoology, EarlyView.
Captive breeding of the Chinese alligator successfully reduced genomic inbreeding but increased the burden of deleterious mutations. Genomic analyses indicate that managing both genetic diversity and genetic load is essential for the long‐term conservation of this critically endangered species.

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

Integrative Zoology, EarlyView.
We produced HiFi long reads and assembled a high‐quality genome for the Guinan toad‐headed lizard—Phrynocephalus guinanensis—and present a comprehensive conservation genomics assessment. Our findings clearly show population structure, a reduced genetic diversity pattern, and a strong bottleneck in demographic history, reaffirming the endangered status ...

EFFECT OF INBREEDING ON SOME PERFORMANCE TRAITS IN SAHIWAL CATTLE

Pakistan Veterinary Journal, 2001
Pedigree, breeding and performance records of a purebred Sahiwal herd maintained at Livestock Experiment Station, Jahangirabad, Khanewal during the period 1939-97 were utilised for the present study. The effect of inbreeding on various performance traits
