1. Globally, both climatic patterns and nitrogen deposition rates show directional changes over time. It is uncertain how woody seedlings, which coexist with herbaceous plants in savannas, respond to concurrent changes in water and nutrient availability. 2. We investigated competition effects between herbaceous vegetation and tree seedlings ( Colophospermum mopane ) under changed water and nutr...
The genus Dickeya contains bacteria causing soft rot of economically important crops and ornamental plants. Here, we report the draft genome sequences of two Dickeya sp. isolates from rotted leaves of Phalaenopsis orchids.
The consumption of plants by animals underlies important evolutionary and ecological processes in nature. Arthropod herbivory evolved approximately 415 Ma and the ensuing coevolution between plants and herbivores is credited with generating much of the macroscopic diversity on the Earth. In contemporary ecosystems, herbivory provides the major conduit of energy from primary producers to consume...
Up to now, the processes of domestication of urban landscapes have been little studied. The public green spaces in the city of Bariloche, an enclave with growing urbanization which lies within the Andino Norpatagonica Biosphere Reserve, offer an opportunity to evaluate cultural molding of the environment. We analyzed different management methods of woody species, both in situ and ex situ, in pa...
abstract soil contamination by heavy metals is yet one of the most important environmental concerns. among heavy metals, nickel and cadmium have dangerous influences on human, animals and plants. the objective of this study was to derive a new model for simultaneous phytoextraction of ni and cd from contaminated soils. consequently, a macroscopic model was derived by combining yield reduction f...
impatiens necrotic spot virus (insv) infects ornamental plants worldwide. it has been reported from almost every ornamental screenhouse in tehran province. insv symptoms include necrotic leaf spot, chlorosis and stunting. heavy losses have been reported from insv in plants such as zinnia elegans, ficus benjamina, viola spp., saintpaulia ioantha, althea spp., cheiranthus cheiri, pelargoniumxhort...
