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

“…The Darwinian theory of natural selection first popularized by Charles Darwin in the mid-19th century has been widely accepted as one of the key mechanisms of evolution. …”

Invasive Phytophthora species affecting broadleaved tree species in urban and landscape settings in Southern Sweden by Blomquist, Mimmi

“…Phytophthora was discovered in the mid 19th century, as the causal agent of the widespread collapse of potato crops throughout Europe. …”

Potato virus Y; the Andean connection by Fuentes, S., Jones, R.A.C., Matsuoka, H., Ohshima, K., Kreuze, Jan F., Gibbs, A.J.

“…Most of the present PVY diversity emerged in the second half of the 19th century, after the Phytophthora infestans epidemics of the mid-19th century destroyed the European crop and stimulated potato breeding. …”

Potato virus A isolates from three continents: their biological properties, phylogenetics and prehistory by Fuentes, S., Gibbs, A., Adams, I., Wilson, C., Botermans, M., Fox, A., Kreuze, Jan F., Boonham, N., Kehoe, M., Jones, R.

“…The PVA and PVY populations apparently arose in the Andes about 18 centuries ago, and were taken to Europe during the Columbian exchange, radiating there after the mid-19th century potato late blight pandemic. PVA’s phylogroup A population diverged more recently in the Andean region, probably after new cultivars were bred locally using Solanum tuberosum spp. tuberosum as a parent. …”

Suitability analysis of a reintroduction of the great bustard (Otis tarda) to Sweden by Fritzson, Karl

The Phylogeography of Potato Virus X Shows the Fingerprints of Its Human Vector by Fuentes, S., Gibbs, A.J., Hajizadeh, M., Pérez, A., Adams, I.P., Fribourg, C.E., Kreuze, Jan F., Fox, A., Boonham, N., Jones, R.A.C.

“…Major clusters A-D probably resulted from expansions that occurred soon after the potato late-blight pandemic of the mid-19th century. Genetic comparisons of the PVX populations of different Peruvian Departments found similarities between those linked by local transport of seed potato tubers for summer rain-watered highland crops, and those linked to winter-irrigated crops in nearby coastal Departments. …”

Brand i Fulufjällets nationalpark by Sander, Jenny

“…Before the 14th century, the samples are too few to support any conclusions about the length of the average fire interval. After the mid-19th century when timber became valuable, fires were almost completely excluded from these forests, due to efficient fire suppression efforts. …”
