Tree mortality may be reflected by individual differences in the ability of plants to produce defensive structures and compounds. We compared the radial growth rates, resin duct production, density, and size between living and dead ponderosa pine trees in northern Arizona using standard dendrochronology...
Any of various trees or shrubs of the genusErythrinain the pea family, native to and widely cultivated in warm regions, having trifoliolate leaves, showy red or orange flowers, and pods containing brightly colored seeds. Also calledcoral bean. ...
