Effects of elevated atmospheric CO2 concentrations, clipping regimen and differential day/night atmospheric warming on tissue nitrogen concentrations of a perennial pasture grass

Forecasting the effects of cli­mate change on nitro­gen (N) cyc­ling in pas­tures requires an under­stand­ing of changes in tis­sue N. A new study pub­lished in AoB PLANTS by Volder et al. shows that elev­ated CO2,…

Nitrogen addition and harvest frequency rather than initial plant species composition, determine vertical structure and light interception in permanent grasslands

Recent biod­iversity exper­i­ments using sown plant com­munit­ies sug­gest a pos­it­ive effect of plant spe­cies diversity on eco­sys­tem func­tion­ing and resource use. However, are these exper­i­mental res­ults applic­able to agri­cul­tur­ally man­aged grass­land? In a new study published…

Responses of beech and spruce foliage to elevated carbon dioxide, increased nitrogen deposition and soil type

Although enhanced car­bon fix­a­tion by forest trees may con­trib­ute sig­ni­fic­antly to mit­ig­at­ing an increase in atmo­spheric CO2, capa­cit­ies for this fix­a­tion vary greatly among dif­fer­ent tree spe­cies and loc­a­tions. In a study pub­lished in AoB…
