Supporting farmers in maintaining and selecting seeds of local varieties [PDF]

, 2009
This book addresses strategies and approaches through which professionals can support informal seed supply, and link these with the conservation and use of the huge genetic resource base of crops and local varieties.

Migration rate, timing of sex, and resident genetic diversity jointly shape effective gene flow during rotifer colonization

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Dispersal is a complex process that affects all living organisms, with the settlement phase being particularly critical. This phase depends on the interaction between the environmental conditions of the new habitat and the biological traits of both resident and immigrant populations.

Inbreeding depression in Holstein cattle in Brazil

Revista 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 Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Evidence of Inbreeding Depression on Human Height

PLoS 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

Pesquisa 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.

Seedling Regeneration Process of Sasa veitchii var. tyugokuensis Over 12 Years Following Small‐Scale Flowering

Plant Species Biology, Volume 41, Issue 3, May 2026.
Sasa species (Poaceae: Bambusoideae) are generally considered monocarpic mass flowering plants. Although seedling regeneration after small‐scale flowering has been largely overlooked, we demonstrated that some seedlings of Sasa veitchii var. tyugokuensis derived from small‐scale flowering survived for 11 years.

The Effects of LED Daylength Extensions on the Daily Activity Patterns of a Greenhouse Biological Control Agent, Aphidius matricariae

Entomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 398-410, May 2026.
We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...

Inbreeding depression in male reproductive traits

Journal of Evolutionary Biology
Abstract Inbreeding frequently leads to inbreeding depression, a general reduction in trait values and loss of fitness, and it appears that some sexually selected traits are especially sensitive to inbreeding, but sperm may be an exception.

Conspecific Scaffold‐Level Genome Assembly Outperforms Heterospecific Chromosome‐Level Assemblies for Assessing Genetic Indicators in a Threatened Marine Fish

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Understanding the genomic architecture of species of conservation concern is essential for fostering effective conservation initiatives. Current biodiversity assessment approaches increasingly incorporate genetic metrics to evaluate the status of species and populations of conservation interest.
