Milkweed ( Asclepias sp.) is an important pollinator genus across North America and a host plant for many butterfly species, notably the monarch Danaus plexippus ). Commercial production of limited to few because most species lack commercial traits, with minimal branching habit, excessive height, color variation. This study used commercially viable weed tuberosa L.), as maternal parent trialed ...

The Indo-Pacific damselfish Abudefduf vaigiensis (Quoy & Gaimard, 1825) was first observed in the Hawaiian Islands in the early 1990s and is now clearly established as a breeding population in the Islands. Sightings of fish with color patterns intermediate between those of A. vaigiensis and the very similar endemic Hawaiian sergeant, Abudefduf abdominalis (Quoy & Gaimard, 1825), suggest that hy...

There is a relatively long history of plant hybridization traced back to ancient time, both from theoretical as well practical perspectives. At first considered an evolutionary dead-end, it was soon recognized have important role in speciation. Beside his work on pea, G.J. Mendel also conducted interspecific using several species including Hieracium. Current knowledge shows that the frequent oc...
