Weed problems and possibilities for their control in salix for biomass [PDF]
Salix is a dedicated arable bioenergy crop that is presently grown on 12,000 ha in Sweden. It has probably the best environmental profile among the arable bioenergy crops grown in Sweden partly because neither fungicides nor insecticides are used in the ...

Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Does pre-dispersal seed predation limit reproduction and population growth in the alpine clonal plant Geum reptans ? [PDF]
We studied the impact of the seed damaging gall midge larva Geomyia alpina on its perennial alpine host plant Geum reptans. We analysed the effect of seed predation on reproduction by seeds, i.e.

Resources, such as nitrogen, are widely hypothesized to underlie the expression and evolution of plant defenses to herbivory. However, resource availability can affect selection on plant defense traits in contrasting ways: resource availability can 1) weaken selection on defense traits by reducing the costs of herbivory, or 2) strengthen selection on ...

We measured the phototactic responses of insects to light at night using LED traps emitting light at four narrowband wavelengths of three intensity levels of relatively equal photon emission. Our data show an interaction between insect order and narrowband spectra, with marked differences in attraction between Lepidoptera and Diptera.
