Toxicity of aqueous extracts of Ilex paraguariensis A.St.-Hil. about Euphorbia heterophylla L. [PDF]

Pest Manag Sci
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Honeybees Collecting Latex From Breadfruit (<i>Artocarpus altilis</i>) in Puerto Rico Reveal a Novel Interaction With Broad Eco-Evolutionary Implications. [PDF]

Ecol Evol
This article showcases a unique natural history observation of honeybees collecting latex from the breadfruit tree (Artocarpus altilis), both nonnative species in Puerto Rico. This represents a unique interaction and here we explore how this behavior may come about in novel ecosystems.
