Maass, Brigitte L.Katunga Musale, DChiuri, W.L.Peters, Michael[Diagnostic survey of livestock production in South Kivu/Dr Congo]Diagnostic survey of livestock production in South Kivu/Dr Congo

Accurate estimation of wildlife population size is central to effective management and conservation but is notoriously difficult for rare and cryptic carnivores. Mark-recapture methods can reliably estimate the abundance of large carnivores but are sensitive to departures from the assumption of e...

Demographic parameters are useful for assessing productivity and dynamics of tropical livestock populations. Common parameters are the annual instantaneous hazard rates, which can be estimated by m/T (where m represents the number of the considered demographic events occurred during the year and ...


Lesnoff, Matthieu[Evaluation of 12-month interval methods for estimating animal-times at risk in a traditional African livestock farming system]Evaluation of 12-month interval methods for estimating animal-times at risk in a traditional African livestock farming system

Presents results of a former survey conducted to establish a baseline understanding of the production system at Elangat Wuas group ranches in Kajiado district, Kenya. Describes the ranch in relation to rainfall, infrastructure, vegetation & land units and nutritional value of the range. Discusses...

The purpose of the manual is to introduce vegetation classification and survey to those with limited botanical or ecological experience. The kinds of people for whom the engaged in policy development to research workers, teachers and students. Apart from providing some background on classificatio...

Increased trade in non-timber forest products (NTFP) has been promoted as one possible means to slow tropical deforestation by increasing the economic value of intact forest. A market surcey of NTFP's occuring in the Capim River basin in eastern Amazonia, Brazil demonstrated that the realitty for...

The paper presents a new and versatile sample unit suitable for rapid assessments of tropical forest in heterogeneous areas. The method uses multiple applications of small and easy-to-apply variable subunits. Compared with any fixed-area approach the sample unit is quick and easy to apply even in...
