Host phylogeny and ecological associations best explain Wolbachia host shifts in scale insects

Molecular Ecology, Volume 32, Issue 9, Page 2351-2363, May 2023., 2023
Abstract Wolbachia are among the most prevalent and widespread endosymbiotic bacteria on Earth. Wolbachia's success in infecting an enormous number of arthropod species is attributed to two features: the range of phenotypes they induce in their hosts, and their ability to switch between host species.

Biological Flora of Britain and Ireland: Viscum album

Journal of Ecology, Volume 111, Issue 3, Page 701-739, March 2023., 2023
Mistletoe is a charismatic parasite of tree crowns with a long history of folklore and connections with Christmas celebrations. This, and its need for light, helps explain why it is most common in human‐made habitats across Europe. Once thought to benignly take just water and nutrients from its host it is now known to take carbon as well which can lead

Molecular phylogenetics of Phyllanthus sensu lato (Phyllanthaceae): Towards coherent monophyletic taxa

TAXON, Volume 70, Issue 1, Page 72-98, February 2021., 2021
Abstract The genus Phyllanthus is paraphyletic as currently circumscribed, with the genera Breynia, Glochidion and Synostemon nested within it. A phylogeny based on nuclear (ITS, PHYC) and chloroplast (matK, accD‐psaI, trnS‐trnG) markers is presented, including 18/18 subgenera and 53/70 sections.

Stem Water Content for Crape Myrtle in Response to Drought, Cold, and Disease Stress

Journal of Sensors, Volume 2020, Issue 1, 2020., 2020
The abiotic and biotic stresses including drought, cold, and disease stress are linked by the fact that they all decrease the availability of water to plant cells. In previous studies, some physiological factors related with plant water status, such as stem sap flow, leaf transpiration rate, and water potential, were used to assess the effects of these
