Is bushmeat just another conservation bandwagon?There is currently great interest in the sustainability of bushmeat hunting (bushmeat being any wild animal by hunted for human consumption). All the big conservation ‘players’ have contributed to the debate, issued statements or funded research. IUCN's World Conservation Congress in October 2000 and the CITES Bushmeat Conference of the Parties in April 2000 both discussed bushmeat. Both organisations have since sponsored initiatives in West and Central Africa aimed at obtaining action on the issue. Major conservation organisations are funding research, including the Wildlife Conservation Society (which has a long track-record in this field) and Conservation International. The World Bank has commissioned a major report on the issue (Bennett & Robinson, 2000). Fauna & Flora International (FFI) is a partner in a UK government-commissioned project identifying priority research areas. Conservation organisations have formed the US-based Bushmeat Crisis Task Force (see http://www.bushmeat.org), of which FFI is a member, and the UK-based Bushmeat Working Group of the Tropical Forest Forum (see http://www.forestforum.org.uk), where academic conservationists and government policy makers can exchange experience and ideas.

The research begins with a brief history of the Banyang-Mbo Sanctuary (BMS) of Nguti, its demographic and geographic dispersion. Next, we aim to identify and analyze the various non-timber forest products, which range from plants, animals, birds and marine species. With the aid of write-ups from the Wildlife Conservation Society (WCS) Cameroon, the spatial distribution of these products, vis-à-vis their proximity to surrounded villages is presented. Effort is equally made to know the activities of the villages and other environmental factors that affect the growth and existence of these products. Three objectives and three hypotheses were formulated to give direction to the study. Convenient and purposive sampling techniques were used in the study with the help of questionnaires for data gathering. The population of the study comprised 141 households in Nguti vicinity and a sample size of 105 respondents obtained with the use of Yaro Yamen’s formula. The statistical tools used for data analysis were frequency, mean and tables of percentages to organize the data collected. The instrument was validated by three experts and reliability justified by a coefficient. The study recommended that education on the development of non-wood forest resources should be practically oriented and existing markets should be sustained while new ones be sought for the sales of the final products.

Mangroves are valuable socio-ecological ecosystems that provide vital goods and services to millions of people, including wood, a renewable natural capital, which is the primary source of energy and construction material for several coastal communities in developing countries. Unfortunately, mangrove loss and degradation occur at alarming rates. Regardless of the protection and close monitoring of mangrove ecosystems in Mexico during the last two decades, mangrove degradation and the loss of biodiversity is still ongoing. In some regions, unregulated and unsustainable mangrove wood harvesting are important causes of degradation. In this context, community-based mangrove forestry through Management Units for Wildlife Conservation could be a cost-effective alternative scheme to manage and conserve mangrove forests, their ecosystem services and biological diversity within and beyond protected areas while providing sustainable local livelihoods and helping reduce illegal logging. The objective of the Management Units is to promote alternative means of production with the rational and planned use of renewable resources based on Management Plans. If implemented with a multidisciplinary perspective that incorporates scientific assessments this conservation strategy may contribute to achieving national and international environmental and biodiversity agreements providing multiple social, ecological and economic benefits from local to global scales.

AbstractThis preprint has been reviewed and recommended by Peer Community In Evolutionary Biology (http://dx.doi.org/10.24072/pci.evolbiol.100033). Much of the immense present day biological diversity of Neotropical rainforests originated from the Miocene onwards, a period of geological and ecological upheaval in South America. We assess the impact of the Andean orogeny, drainage of lake Pebas, and closure of the Panama Isthmus on two clades of trees (Cremastosperma, c. 31 spp.; and Mosannona, c. 14 spp.; both Annonaceae) found in humid forest distributed across the transition zones between the Andes and Western (lowland) Amazonia and between Central and South America. We inferred phylogenies based on c. 80% of recognised species of each clade using plastid and nuclear encoded sequence markers, revealing similar patterns of geographically restricted clades. Using molecular dating we showed that diversifications in the different areas occurred in parallel, with timing consistent with Andean vicariance and Central American geodispersal. In apparent contradiction of high dispersal abilities of rainforest trees, Cremastosperma clades within Amazonia are also geographically restricted, with a southern/montane clade that appears to have diversified along the foothills of the Andes sister to one of more northern/lowland species that diversified in a region once inundated by lake Pebas. Ecological niche modelling approaches show phylogenetically conserved niche differentiation, particularly within Cremastosperma. Niche similarity and recent common ancestry of Amazon and Guianan Mosannona species contrasts with dissimilar niches and more distant ancestry of Amazon, Venezuelan and Guianan species of Cremastosperma suggesting that this element of the similar patterns of disjunct distributions in the two genera is instead a biogeographic parallelism, with differing origins. The results provide further independent evidence for the importance of the Andean orogeny, the drainage of Lake Pebas, and the formation of links between South and Central America in the evolutionary history of Neotropical lowland rainforest trees.
