Toward plant breeding for multicrop systems [PDF]

open access: yesProceedings of the National Academy of Sciences, 2023
Increasing cropping system diversity has great potential to address environmental problems associated with modern agriculture, such as erosion, soil carbon loss, nutrient runoff, water pollution, and loss of biodiversity. As with other agricultural sciences, plant breeding has primarily been conducted in the context of dominant monoculture cropping ...

Geographic variation in breeding system and environment predicts melanin-based plumage ornamentation of male and female Kentish plovers

open access: yesBehavioral Ecology and Sociobiology, 2015
Sexual selection determines the elaboration of morphological and behavioural traits and thus drives the evolution of phenotypes. Sexual selection on males and females can differ between populations, especially when populations exhibit different breeding ...

Cyber-agricultural systems for crop breeding and sustainable production.

open access: yesTrends in Plant Science, 2023
The cyber-agricultural system (CAS) represents an overarching framework of agriculture that leverages recent advances in ubiquitous sensing, artificial intelligence, smart actuators, and scalable cyberinfrastructure (CI) in both breeding and production ...

Biopower and an ecology of genes : seeing livestock as meat via genetics [PDF]

open access: yes, 2015
This book chapter focuses on some of the implications of what has been represented as a radical change in livestock breeding for thinking about meat in relation to living farm animals: the use of genetic techniques in selecting breeding animals.

Genetic Parentage Analysis Confirms a Polygynandrous Breeding System in the European Grayling (Thymallus thymallus)

open access: yesPLoS ONE, 2015
Knowing the breeding system of a species is important in order to understand individual variation in reproductive success. Large variation in reproductive success and thus reproductive skew strongly impacts on the effective number of breeders and thus ...

Le bassin laitier du Livradois-Forez, de l’analyse historique aux modèles de dynamique

open access: yesM@ppemonde, 2018
This paper models the dynamics of the Livradois-Forez dairy basin. The approach is based on a progressive formalization. We begin by establishing and sequencing the history of the dairy basin, then we aggregated the information into an integrating ...
