A major QTL affects temperature sensitive adult lethality and inbreeding depression in life span in Drosophila melanogaster

BMC Evolutionary Biology, 2008
Background The study of inbreeding depression has major relevance for many disciplines, including conservation genetics and evolutionary biology. Still, the molecular genetic basis of this phenomenon remains poorly characterised, as knowledge on the ...

Inferences About Inbreeding Depression Based on Changes of the Inbreeding Coefficient [PDF]

Evolution, 1990
In a mixed-mating population, the fitness of selfed individuals, relative to outcrossed individuals, can be estimated from observed changes of the inbreeding coefficient F. In general, three measurements of F, or two measurements of F and one of the selfing rate, spanning two generations are needed.

Phytohormonal and Transcriptomic Mechanisms of Multigenerational Stress Memory in Wheat Under Weed Competition

Plant, Cell &Environment, Volume 49, Issue 6, Page 3436-3454, June 2026.
ABSTRACT Multigenerational stress exposure induces stress memory in plants, influencing resource allocation, defence mechanisms, and productivity. Weed competition imposes both resource‐based (abiotic) and allelopathic (biotic) stress, engaging overlapping hormonal pathways.

Removing exogenous information using pedigree data

, 2011
Management of certain populations requires the preservation of its pure genetic background. When, for different reasons, undesired alleles are introduced, the original genetic conformation must be recovered.

Morphometric differences in the grasshopper Cornops aquaticum (Bruner, 1906) from South America and South Africa [PDF]

, 2008
The semi-aquatic grasshopper Cornops aquaticum is native to South America and inhabits lowlands from southern Mexico to Central Argentina and Uruguay. It is host-specific to aquatic plants in the genera Eichhornia and Pontederia.

Estimating the Abundance of a Cryptic, Endangered Marsupial, Mala (Lagorchestes hirsutus) Using Microsatellite and Single Nucleotide Polymorphism Genotyping Panels

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We developed a species‐specific SNP panel for non‐invasive population monitoring of the mala (Lagorchestes hirsutus, Central Australian subspecies), an Australian macropod that is extinct in the wild, and conserved inside four predator‐free reserves and on one offshore island.

Detecting inbreeding depression in a severely bottlenecked, recovering species: The little spotted kiwi (Apteryx owenii)

, 2014
Population bottlenecks reduce genetic variation and population size. Small populations are at greater risk of inbreeding, which further erodes genetic diversity and can lead to inbreeding depression.

Genetic Diversity, Population Structure and Evidence of Genetic Bottleneck in Geoffroea decorticans (Fabaceae): Implications for Conservation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We documented genetic variation, population structure, and bottleneck signals in Geoffroea decorticans (Fabaceae) populations across the Atacama Desert and emphasize the urgency of genetic monitoring. Conservation plans should prioritize populations based on genetic information including those with low diversity, strong bottleneck signals and high ...
