A study was carried out in a 20 year-old secondary forest situated on the campus of the University of Ucayali, 4 km from the city of Pucallpa, Peruvian Amazon. Botanical and ethno-botanical inventories were made of all trees greater than 10 cm dbh growing on an half hectare plot on very demineral...

In several regions of the Congo Basin the call of an endangered duiker is traditionally used by hunters to attract animals. We explore the possibility to standardize this call method to improve day time transect counts. Our study shows that the call is particularly efficient for the most common d...

Located on the fringe of the last tropical rainforests of Sumatra, rubber agroforests are known to conserve the main ecological functions of the primary forest, including a large part of its biodiversity. Nowadays these smallholder plantations are under threat. The regular rise of natural rubber ...

This paper critically evaluates and discusses some of the methodological practicalities of applying a combined participatory and small-scale survey approach to investigating rural livelihood strategies of people living in the humid forest zone of Southwest Cameroon, Southeast Nigeria and Southwes...

Dung counts have been widely used to estimate duiker abundance and densities in tropical African forests. However, one of the major limitations of this method is that species’ identification of dung based on morphological characteristics is extremely difficult in most cases. Some authors made the...

A preliminary and limited nematode survey was conducted in the three main banana-producing areas of South Africa, namely Onderberg, Hazyview (both in Mpumalanga Province), and the South Coast of Kwazulu/Natal Province. Root and soil samples were taken from ‘Chinese Cavendish’ (AAA), ‘Dwarf Cavend...

In Cameroon, parasitism by Loranthaceae is a limiting factor of the avocado tree cultivation as well as the many diseases and pests which have been better studied. Inventories were carried out in the agroecosystems of five localities around Yaounde, Cameroon. In each one of these localities, all ...

The African rice gall midge, Orseolia oryzivora Harris and Gagné has become one of the major biotic constraints to rice production in Nigeria. A survey of gall midge distribution in Nigeria showed that the pest was common in the savannah and forest zones on rice grown under lowland ecologies. End...

survey of rice insect pests conducted during 1983–87 in Nigeria revealed 70 species of pests, 14 parasitoids and two predators. Both incidence and severity of pests varied considerably across different climatic zones and rice agro‐ecosystems. Thirteen Insects were classified as major pests. They ...

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...
