A test for Allee effects in the self-incompatible wasp-pollinated milkweed Gomphocarpus physocarpus [PDF]

, 2009
It has been suggested that plants which are good colonizers will generally have either an ability to self-fertilize or a generalist pollination system. This prediction is based on the idea that these reproductive traits should confer resistance to Allee ...

Chloroplast Genomes of Croton alabamensis and Croton bonplandianus (Euphorbiaceae): Comparative Analysis With Related Croton Species

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Croton chloroplast genomes exhibit substantial structural diversity driven mainly by asymmetric inverted repeats (IRs) contraction and expansion, despite highly conserved gene content. IR boundary shifts predominantly involved the LSC region, indicating an LSC‐driven evolutionary pattern. The preliminary phylogenomic analyses confirmed the monophyly of
