Suppression of annual bromes impacts rangeland: Animal responses
Presence of annual bromes (Bromus spp.), introduced annual weedy grasses, can alter seasonal patterns of forage production and quality and require management changes for efficient use of infested rangelands. We determined biological impacts of the presence of brome by comparing livestock performance on brome infested rangeland to similar sites on which brome had been suppressed by autumn applic...
متن کاملConvergent evolution of genes controlling mitonuclear balance in annual fishes
Complexes of the respiratory chain are formed in a complex process where nuclearlyand mitochondrially-encoded components are assembled and inserted into the inner mitochondrial membrane. The coordination of this process is named mitonuclear balance and experimental manipulations of mitonuclear balance can increase longevity of laboratory species. Here, we investigated the pattern of positive se...
متن کاملControlling Annual Bluegrass (Poa annua L.) Summer Patch Disease with Faeriefungin
Faeriefungin, an antibiotic produced by the actinomycete Streptomyces griseus var. autotrophicus MSU-32058/ATCC 53668, was tested in field trials on golf course fairways to determine if it could control annual bluegrass (Poa annua L.) summer patch effectively. Test sites with a history of severe summer patch outbreaks caused by Magnaporthe poae Landschoot and Jackson were chosen for study. Faer...
متن کاملFactors controlling evaporation and energy partitioning beneath a deciduous forest over an annual cycle
The energy balance components were measured above the ground surface of a temperate deciduous forest over an annual cycle using the eddy covariance technique. Over a year, the net radiation at the forest floor was 21.5% of that above the canopy, but this proportion was not constant, primarily because of the distinct phenological stages separated by the emergence and senescence of leaves. The do...
متن کاملParallel evolution of genes controlling mitonuclear balance in short‐lived annual fishes
The current molecular understanding of the aging process derives almost exclusively from the study of random or targeted single-gene mutations in highly inbred laboratory species, mostly invertebrates. Little information is available as to the genetic mechanisms responsible for natural lifespan variation and the evolution of lifespan, especially in vertebrates. Here, we investigated the pattern...
