Veld condition indexing : relevance to wildlife management?
… resource. · Measurement and monitoring of veld condition is an important management tool. Management methods need to be centred on the objectives of the livestock farm or game reserve being managed. Veld condition assessments and their use in managing stocking rates are dependent on the range …

An Evaluation of Relative Weight as an Indicator of Body Composition and Nutritional Status in Wild Fish
Condition indices are widely used to generate biological insight. However, purported relationships to indices are imprecise or inconsistent in the wild. I investigated factors influencing relative weight (Wr), a condition index commonly applied to fish. I first examined the relationship of Wr to …
