Potted plants have been reported to uptake VOCs and help “cleaning” the air. This paper presents results of a laboratory study in which two species (peace lily Boston fern) three kinds substrates (expanded clay, soil, activated carbon) were tested monitored on their capacity deplete formaldehyde CO2 glass chamber. Formaldehyde selected as indicators evaluate biofiltration efficacy 28 different ...

The recent uplift of the tropical Andes (since the late Pliocene or early Pleistocene) provided extensive ecological opportunity for evolutionary radiations. We test for phylogenetic and morphological evidence of adaptive radiation and convergent evolution to novel habitats (exposed, high-altitude páramo habitats) in the Andean fern genera Jamesonia and Eriosorus. We construct time-calibrated p...
