Inbreeding and Endangered Species Management: Is New Zealand Out of Step with the Rest of the World?

Conservation Biology, 2006
Abstract:  There is growing evidence that inbreeding can negatively affect small, isolated populations. This contrasts with the perception in New Zealand, where it has been claimed that native birds are less affected by inbreeding depression than threatened species from continental regions.

A new breeding system using gynogenesis and sex-reversal for fast inbreeding in carp

Theoretical and Applied Genetics, 1984
A new breeding technique is demonstrated using gynogenesis and sex-reversal. The essence of this method is an adequate alternation of gynogenesis and sibmating with a maximal increase in the coefficient of inbreeding. The rate of this increase considerably exceeds that characteristic of sibmating.

Observations of Double Brooding and Inbreeding of Piping Plovers on Fire and Westhampton Islands, New York

Northeastern Naturalist, 2019
In the summer of 2016, we observed a pair of Charadrius melodus (Piping Plover) successfully hatch 2 nests at Fire Island National Seashore and fledge chicks from both broods. Double brooding is rare among Piping Plovers, and fledging chicks from both broods is rarer still.

The Functional Genomics of Inbreeding Depression: A New Approach to an Old Problem

BioScience, 2010
The fitness consequences of inbreeding have attracted the attention of biologists since the time its harmful effects were first recognized by Charles Darwin. Although inbreeding depression has been a central theme in biological research for over a century, little is known about its underlying molecular basis.

Sex‐Specific Consequences of Recent Inbreeding in an Ancestrally Inbred Population of New Zealand Takahe

Conservation Biology, 2003
Abstract: Although the negative effects of close inbreeding in captive populations are well known, inbreeding in small, free‐ranging populations is less well understood. During the mid‐1980s, small numbers of the flightless Takahe (   Porphyrio hochstetteri   ) were ...

REALISATION OF NEW VARIABILITY BY MEANS OF INBREEDING IN SOME INDIGENOUS RED GRAPEVINE CULTIVAR OF VERONA (NORTH EAST ITALY)

Acta Horticulturae, 2003
Corvina, Corvinone and Rondinella, the three main grape varieties cultivated in Verona, are characterized by a high phenotypic homogeneity. Self-pollination has been used to give expression to the intrinsic variability present in the genome of these varieties.

Using artificial intelligence languages for the calculation of inbreeding coefficients —New tools for an old problem

Computers in Biology and Medicine, 1987
A computer program was written for the calculation of inbreeding coefficients in pedigrees. Trees and recursivity allow a very efficient codification into LISP or PROLOG.

New method of estimating inbreeding in large semi-isolated populations with application to historic Britain

HOMO, 2001
The purpose of this paper is to introduce a new method of estimating inbreeding in large, relatively isolated, populations over historic times, to demonstrate its application, and indicate some of its limitations and future developments. The method is based on the "paradox" of genealogy, and requires only that the variation of the population size be ...

Use of an interspecific hybrid in identifying a new allelic specificity generated at the self-incompatibility locus after inbreeding in Lycopersicon peruvianum

Theoretical and Applied Genetics, 1986
An interspecific hybrid between Lycopersicon esculentum (♀) and L. peruvianum has been raised by embryo rescue in vitro and used to confirm the presence of a new S-allelic specificity in its inbred L. peruvianum parent, a plant derived by enforced bud self-pollination of a self-incompatible clone with the genotype S 1 S 2.

Academic inbreeding: new estimates

By analyzing nearly 8,000 recruitments for assistant professor positions in France between 2017 and 2024, Olivier Godechot, Rachel Issiakou, Yann Renisio, and Adrien Rougier revisit the long-standing and controversial issue of academic inbreeding.
