Allelopathy is the stimulatory or inhibitory effect of one plant on another by release phytochemicals. It can affect competitive interactions between plants, but strength may depend tissue donor and phylogenetic relatedness interacting species. Here, we examined allelopathic effects invasive garden lupine Lupinus polyphyllus Lindl. (Fabaceae) six native herbs from three families (Asteraceae, Ca...

Neoparaphytoseius charapa n. sp. is described, based on the morphology of adult females and males collected on Inga edulis (Mart.) (Fabaceae) in northeastern Peru. Neoparaphytoseius Chant & McMurtry is redefined on the basis of the new species and re-examination of its type species N. sooretamus Chant & McMurtry. 

Green roofs provide ecosystem services through evapotranspiration and nutrient cycling that depend, among others, on plant species, substrate type, and substrate depth. However, no study has assessed thoroughly how interactions between these factors alter ecosystem functions and multifunctionality of green roofs. We simulated some green roof conditions in a pot experiment. We planted 20 plant s...
