Bare soil evolved a maximum of 7 g CO₃/m²/day in summer and a minimum of 1 g/m²/day in winter; the Q₁₀ was 3. Root respiration, i.e. the difference in...

The influence of competition on ramet populations of C. esculentus was studied experimentally at a site near Harare, Zimbabwe. A range of ramet densit...

Dispersal parameters are critical for modelling spatially dynamic populations yet remain among the most difficult to quantify. Linyphiid spider aerial...

Along two traverses near Mineral, Virginia (USA) (where soil metal concentrations vary greatly because of the natural weathering of sulphide mineral d...

In the basement complex country of the area, ranges of rocky hills are separated by a deeply weathered pedeplain dissected by seasonal watercourses. I...

Temperatures were measured in a perennial ryegrass crop in the field and an attempt was made to relate temperature to growth. The instruments used are...

In an investigation of the relation between weather and the growth of barley, the approach used depended on calculation of the exchange of CO2 and wat...

Barley cv. Proctor grown over a wide range of conditions had a relatively stable mean weight/grain of 34.9 ( plus or minus 2.84) mg (range 29.3-41 mg)...

Ecological restoration is urgently needed to arrest and reverse land degradation, reinstate ecosystem services and recover threatened species. Tree pl...

The upward flux of CO₂ at the soil surface was calculated from the weight increase of soda lime granules exposed inside a glass tank covering 400 cm² ...
