Evolutionary constraints in host shifts: Limited adaptation of Plutella xylostella to cardenolide‐defended Erysimum cheiranthoides

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 501-516, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Coevolutionary arms races between plants and insects, in which gains of novel plant defences select for counteradaptations in herbivores, are key drivers of biodiversity.

Interactive effects of inbreeding and endocrine disruption on reproduction in a model laboratory fish

open access: yesEvolutionary Applications, 2013
Inbreeding depression is expected to be more severe in stressful environments. However, the extent to which inbreeding affects the vulnerability of populations to environmental stressors, such as chemical exposure, remains unresolved.

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

open access: yesEvolution, 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.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

open access: yesBiological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Genetic Diversity, Population Structure and Differentiation of Farmed and Wild African Catfish (Clarias gariepinus) in Nigeria

open access: yesEvolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT The African catfish (Clarias gariepinus) is a commercially important species, for both fisheries and aquaculture, and is now the most commonly farmed fish in sub‐Saharan Africa. However, knowledge about the genetic diversity and population structure of natural and farmed populations, which is crucial for effective conservation and sustainable ...

Inbreeding depression in Holstein cattle in Brazil

open access: yesRevista Brasileira de Zootecnia
The objective of this study was to evaluate inbreeding depression in Holstein cows in Brazil, considering their 305-day milk production (MP), age of first calving (AFC), and calving interval (CI).

The Genetic Interpretation of Inbreeding Depression and Outbreeding Depression [PDF]

open access: yesEvolution, 1991
Inbreeding with close relatives and outbreeding with members of distant populations can both result in deleterious shifts in the means of fitness-related characters, most likely for very different reasons. Such processes often occur simultaneously and have important implications for the evolution of mating systems, dispersal strategies, and speciation.

Evidence of Inbreeding Depression on Human Height

open access: yesPLoS Genetics, 2012
Stature is a classical and highly heritable complex trait, with 80%-90% of variation explained by genetic factors. In recent years, genome-wide association studies (GWAS) have successfully identified many common additive variants influencing human height; however, little attention has been given to the potential role of recessive genetic effects. Here,

Inbreeding depression in crambe

open access: yesPesquisa Agropecuária Tropical, 2016
Inbreeding depression in plants, caused by selfing or crossing among plants with a high degree of relatedness, is a genetic phenomenon that affects quantitative traits. This study aimed at verifying the occurrence of inbreeding depression in crambe progenies originated from selfing, in comparison with open pollination progenies.
