This approach differs from that used by many laboratories that dry, sieve and subsample soil prior to analysis. However, our objective was to screen and analyse a large number of soils quickly, safely and at low cost to provide a reliable estimate of trace metals in garden soils (Rouillon ...
Identifying early life-stage transitions limiting seagrass recruitment could improve our ability to target demographic processes most responsive to management. Here we determine the magnitude of life-stage transitions along gradients in physical disturba

Here we address patterns and drivers of the shoot senescence of perennial herbaceous plants. We present a comparative study of 231 temperate species, ranging from spring ephemeroids to species senescing in late autumn, in a common botanical garden collection. We assessed senescence by measuring size...

affected plants becomes discolored or develops spots. The needles and shoots may eventually wilt, die and fall off the tree. Botrytis blight is often identified by gray-brown spore masses on twigs, which may experience dieback as decay begins at the tips of leaves and moves along to the ...
Aphids are tiny insects that attach themselves to the leaves and stems of the foxglove plant. When they do they eat the plant and cause it to become discolored. Over time as the infestation of aphids gets worse the plant will die. Nearby plants will also become infected with aphids after ...
