Gudali cattle of West and Central Africa by Tawah, C.L., Rege, J.E.O.

“…Under the prevailing circumstances in the pastoral systems, natural selection is the primary force affecting any circumstances in the pastoral systems, natural selection is the primary force affecting any genetic change and, as a result, animals tend to perform relatively poorly. …”

In situ conservation of forest genetic resources by Vinceti, Barbara, Thomas, Evert

“…For FGR, in situ conservation refers to the genetic conservation of tree and other woody plant species in their natural environments by targeting individual populations of these species(FAO, 2014a) with the aim of maintaining or increasing their evolutionary and adaptive potential using natural selection as a driver. In situ conservation is intrinsically dynamic because the populations maintain ecological interactions with other biota and undergo evolutionary processes such as natural selection, genetic drift, and gene flow and mutation (FAO, 2014a).In situ conservation is also the most efficient option for conserving the gene pools of tree species (Kelleher, 2018) because its cost is lowerper unit of genetic diversity than that of ex situ conservation (Gapare, 2013).The in situ conservation of FGR is carried out typically in protected areas and managed forests(FAO, DFSC and IPGRI, 2001) and in forest reserves or stands designated specifically for the genetic conservation of a given species (FAO, 2014a). …”

Multiple genomic signatures of selection in goats and sheep indigenous to a hot arid environment by Kim, E.S., Elbeltagy, A.R., Aboul-Naga, A.M., Rischkowsky, Barbara A., Sayre, B., Mwacharo, Joram M., Rothschild, Max F.

A dynamic population of weedy rye by Suneson, C.A., Rachie, K.O., Khush, G.S.

“…The dramatic take‐over by this interspecific derived population can be ascribed to a favorable climate and soil, and an unusual opportunity for continued introgression with diverse cultivars of rye.We encourage further study of this example of genetic introgression under conditions of natural selection. Information may be applicable to rye breeding, new species (Triticale) production, and population genetics. …”

Property rights and the management of animal genetic resources: how to secure access to drylands resources for multiple users by Anderson, Simon, Centose, Roberta

Resistance to endoparasites in small ruminants: Genetic considerations by Woolaston, R.R.

Genetic dilution of the Ethiopian Boran cattle by Alemayehu, N., Gebru, G., Ayalew, W.

“…This paper is originally designed to address some of the issues related to the causes of Boran breed admixing and the pastoralists perception on Boran breed genetic dilution to be presented as a part of future large scale study on problems related to Boran breed conservation and Development.The issues discussed include causes of genetic dilution; drought and conflict; restocking; natural selection; traditional resource management; deliberate crossbreeding; preliminary finding on perception of pastoral communities on genetic admixtures; and what should be done in the future.…”

Transgenerational phenotypic plasticity: can parental host plant experience affect the phenotype of the offspring? : a study in behavior and physiology in Spodoptera littoralis by Rösvik, Axel

Learning selection: a model for planning, implementing, and evaluating participatory technology development by Douthwaite, Boru, Park, J., Keatinge, J.D.H.

“…At the core of the model is the interactive experiential learning process —learning selection (LS)— that is analogous to natural selection in the living world. In learning selection stakeholders engage with a new technology, individually playing the evolutionary roles of novelty generation and selection, and in their interactions creating recombinations of ideas and experiences and the promulgation of beneficial novelties. …”
