Abstract

We studied the harlequin mantella along 18 transects from Fohisokina and Soamasaka during three different seasons of the year. Transects were installed in three dominant habitats at both sites. In total, we encountered the target species 62 times from all of our surveys. Several encountered animals vary between sites and seasons. No frog was observed during the winter. However, frog size is significantly different between sexes which females are larger than males. [ABSTRACT FROM AUTHOR]

17. Habitat use, roost selection and conservation of bats in Tsingy de Bemaraha National Park, Madagascar.

Abstract

Although the land mammals of Madagascar have been the subject of many studies, the island's bats have yet to feature prominently on the research or conservation agenda. In this study we used mist nets, acoustic sampling and cave surveys to assess habitat use, seasonality and roost selection. Four microchiropteran species (Triaenops rufus, T. furculus, Miniopterus manavi and Myotis goudoti) appeared to be strongly associated with the forest interior based on trapping, but analysis of time-expanded echolocation recordings revealed that T. rufus and M. manavi were frequently recorded in forest edges and clearings. Bat activity was significantly lower inside the forest than at the interface between agricultural land and forest. The caves visited most often by tourists were low in bat abundance and species richness. Anjohikinakina Cave, which was visited infrequently by people, was used by five species and contained between 54% (winter) and 99% (summer) of bats counted in 16 caves and is a site of national importance for bat conservation. Hipposideros commersoni was only netted in our study area during October and may be a migrant to the site or present but inactive during the austral winter. The forest surrounding the caves is therefore important because it provides cover for emerging bats and a potential source of invertebrate prey whilst the forest edge is important to foraging bats.

20. Understanding Livelihoods for Protected Area Management: Insights from Northern Madagascar

Abstract

Protected areas (PA) are the most common approach to conservation globally; however, their effectiveness is unclear when neighbouring human communities are highly natural resource dependent. While forest-based livelihoods provide important income for rural communities, destructive livelihoods such as charcoal production can also threaten the sustainability of PAs. We aimed to understand drivers of livelihood choices in communities surrounding a proposed PA threatened by charcoal production in northern Madagascar, to inform management strategies that promote forest conservation without negatively impacting local communities. We used semi-structured interviews and focus groups to understand local livelihood dynamics using the Sustainable Livelihoods Framework (SLF). Our findings showed charcoal production to be an important livelihood used to deal with annual food insecurity. Agricultural yields were limited by a lack of assets for clearing land and building protective fences. Households were also hesitant to invest in agriculture due to the perceived risks associated with unpredictable rainfall and cattle grazing. Furthermore, while fishing was an important livelihood for filling income gaps, declining catches due to overexploitation across the study region appeared to be increasing the need for charcoal production. While improvements to agriculture were perceived to be promising strategies for reducing forest-dependence, a landscape approach to conservation in the region will be necessary in order to promote sustainability of all livelihoods and to reduce overall pressures on forest resources.

22. Le droit de la protection de la nature à Madagascar : Entre centralisme et consensualisme

Abstract

La diversité biologique de Madagascar est caractérisée par une richesse et une endémicité exceptionnelles. Ces caractéristiques motivent le classement de l'île parmi les zones vulnérables et nécessitent par ailleurs la mise en place de mesures de protection particulières. Cependant, la protection de la biodiversité est tributaire de la stabilité du pouvoir et de la volonté réelle des dirigeants à oeuvrer en faveur de cette protection. Afin de pallier ces problèmes, il a été décidé d'impliquer les communautés locales riveraines.
