Genomic Assessment of Reintroduced African Wild Dogs Informs Conservation Translocations

Animal Conservation, EarlyView.
Few reintroduction and translocation programs incorporate genomic assessments into management planning, despite ongoing debate over how founder individuals should be selected. Here, we assess the genomic composition of reintroduced African wild dog (Lycaon pictus) populations in private reserves in South Africa, comparing them with a free‐roaming ...

Estimation of inbreeding depression in Psidium guajava through seed attributes using S0, S1, and S2 families

Acta Scientiarum. Agronomy
Inbreeding depression, resulting from self-pollination or mating between closely related plants, primarily impacts quantitative traits. This study aimed to assess inbreeding depression in guava seeds from two generations of self-pollination (S1 and S2 ...

Inbreeding depression in the Lizard canary breed estimated by pedigree analysis

Czech Journal of Animal Science, 2016
The influence of inbreeding depression on phenotypic traits of the Lizard canary from an Italian breeder was evaluated. The following traits were studied: birds' life span, number of surviving offspring, and morphological traits (type of plumage ...

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Pest‐preservation paradox among insects

Conservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Do Habitat Restoration Efforts and the Associated Releases of Hatchery‐Reared Fish Affect the Genetic Diversity and Integrity of Native Brown Trout Populations?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Habitat restoration may protect brown trout (Salmo trutta) populations from loss of genetic diversity by increasing environmental carrying capacity and, consequently, population size. However, the accompanying release of hatchery‐reared fish may threaten the genetic integrity of native populations through introgression.

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

Ibis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

EFFECT OF INBREEDING ON LOIN AND FAT DEPTH IN HUNGARIAN LANDRACE PIGS [PDF]

Poljoprivreda, 2007
Pedigree and field test data - collected between 1997-2005 - were analyzed in a group of 68062 Hungarian Landrace pigs. The analysed traits were loin depth (LD), fat depth1 (FD1) and fat depth2 (FD2).

Hatching failure and embryo mortality in endangered populations of Eurasian Curlew (Numenius arquata)

Ibis, EarlyView.
Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

Population genetic analysis of the endangered Mottled Duskywing butterfly (Erynnis martialis) informs species reintroduction

Insect Conservation and Diversity, EarlyView.
Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...
