Association of putatively adaptive genetic variation with climatic variables differs between a parasite and its host

open access: yesEvolutionary Applications, 2021
Parasitism is a pervasive phenomenon in nature with the relationship between species driving evolution in both parasite and host. Due to their host‐dependent lifestyle, parasites may adapt to the abiotic environment in ways that differ from their hosts ...

Toward a macroevolutionary understanding of live-leaf flammability in plant species of fire-prone forests. [PDF]

open access: yesAm J Bot
Abstract Premise The flammability of live leaves in canopies varies considerably among plant species. Identifying macroevolutionary processes that shape variation in leaf flammability contributes to an understanding of the phylogenetic underpinnings of wildfire dynamics.

Evolution of pollen morphology in Loranthaceae [PDF]

open access: yesGrana, 2017
Earlier studies indicate a strong correlation of pollen morphology and ultrastructure with taxonomy in Loranthaceae. Using high-resolution light microscopy and scanning electron microscopy imaging of the same pollen grains, we document pollen types of 35 genera including 15 studied for the first time.

Eocene Loranthaceae pollen pushes back divergence ages for major splits in the family [PDF]

open access: yesPeerJ, 2017
Background We revisit the palaeopalynological record of Loranthaceae, using pollen ornamentation to discriminate lineages and to test molecular dating estimates for the diversification of major lineages. Methods Fossil Loranthaceae pollen from the Eocene

Thionins [PDF]

open access: yes, 1999
The general designation of thionins has been proposed for a family of homologous peptides that includes purothionins, which were first isolated from wheat seeds (Balls el #/., 1942) and their homologues from various taxa that have been named viscotoxins ...
