Artisanal extraction and traditional knowledge associated with medicinal use of Crabwood Oil (Carapa guianensis Aublet.) in a peri-urban Várzea environment in the Amazon Estuary. Repositório Alice
NARDI, M.; LIRA-GUEDES, A. C.; CUNHA, H. F. A.; GUEDES, M. C.; MUSTIN, K.; GOMES, S. C. P..
Varzea forests of the Amazon estuary contain species of importance to riverine communities. For example, the oil extracted from the seeds of crabwood trees is traditionally used to combat various illnesses and as such artisanal extraction processes have been maintained. The objectives of this study were to (1) describe the process involved in artisanal extraction of crabwood oil in the Fazendinha ProtectedArea, in the state ofAmap´a; (2) characterise the processes of knowledge transfer associated with the extraction and use of crabwood oil within a peri-urban riverine community; and (3) discern medicinal uses of the oil.The data were obtained using semistructured interviews with 13 community members involved in crabwood oil extraction and via direct...

Biodiversity, threats and conservation challenges in the Cerrado of Amapá, an Amazonian savanna. Repositório Alice
MUSTIN, K.; CARVALHO, W. D.; HILÁRIO, R. R.; COSTA-NETO, S. V.; SILVA, C. R.; VASCONCELOS, I. M.; CASTRO, I. J.; EILERS, V.; KAUANO, E. E.; MENDES-JÚNIOR, R. N. G.; FUNI, C.; FEARNSIDE. P. M.; SILVA, J. M. C.; EULER, A. M. C.; TOLEDO, J. J..
An Amazonian savanna in northern Brazil known as the Cerrado of Amapá is under imminent threat from poor land-use planning, the expansion of large-scale agriculture and other anthropogenic pressures. These savannas house a rich and unique flora and fauna, including endemic plants and animals. However, the area remains under-sampled for most taxa, and better sampling may uncover new species. We estimate that only ~9.16% of these habitats have any kind of protection, and legislative changes threaten to further weaken or remove this protection. Here we present the status of knowledge concerning the biodiversity of the Cerrado of Amapá, its conservation status, and the main threats to the conservation of this Amazonian savanna. To secure the future of these...

Hydrodynamics and seed dispersal in the lower Amazon. Repositório Alice
CUNHA, A. C. da; MUSTIN, K.; SANTOS, E. S. dos; SANTOS, E. W. G. dos; GUEDES, M. C.; CUNHA, H. F. A.; ROSMAN, P. C. C.; STERNBERG, L. da S. L..
The transport of seeds by water, i.e. hydrochory, is a key mechanism of long-distance dispersal constrained by the attributes of the seed and hydrodynamics. In the freshwater Amazon estuary, river hydrodynamics are influenced by seasonal changes in precipitation and tidal cycles. It is not known to what extent a hydrodynamic model may be able to predict seed dispersal. Here we parameterised a simulation model (SisBaHia) to estimate maximum seed dispersal distances per tidal cycle, which were then compared with data from in situ seed dispersal experiments. The study was conducted along a 27-km stretch of a tributary of the Amazon estuary, using the seeds of a widely distributed riparian tree?Carapa guianensis (Meliaceae). Based on the simulation model,...

Phenology of the multi-use tree species Carapa guianensis in a floodplain forest of the Amazon Estuary. Repositório Alice
DANTAS, A. R.; LIRA-GUEDES, A. C.; MUSTIN, K.; APARÍCIO, W. C. S.; GUEDES, M. C..
Carapa guianensis is a multi-use tree species that is used for the production of timber and non-timber forest products (NTFPs) that are used and sold by rural Amazonian populations. Here we aimed to evaluate the phenophases of C. guianensis in várzea forest and relate them to climatic seasonality. Phenophases of fl owering (fl ower buds and open flowers), fruiting (unripe and ripe fruits), and leaf fl ush and leaf fall were recorded for 30 individual trees during a 25 month period. Relationships between rainfall and the proportion of trees in each phenophase were tested using Generalised Linear Models with quasi-binomial errors. Flowering was found to peak in the driest months of the year (September to December), while fruiting peaked during the wettest...

The fate of an Amazonian Savanna: government land-use planning endangers sustainable development in Amapa, the most protected Brazilian State. Repositório Alice
HILÁRIO, R. R.; TOLEDO, J. J. de; MUSTIN, K.; CASTRO, I. J.; COSTA-NETO, S. V.; KAUANO, E. E.; EILERS, V.; VASCONCELOS, I. M.; MENDES-JÚNIOR, R. N.; FUNI, C.; FEARNSIDE, P. M.; SILVA, J. M. C.; EULER, A. M. C.; CARVALHO, W. D. de.
Although Amapá is the most protected Brazilian state, the same level of protection does not extend to its savannas. These are currently suffering increased pressure from threats including large-scale agriculture, particularly the expansion of soybean plantations. In September 2016, the Government of Amapá presented a zoning proposal (Zoneamento Socioambiental do Cerrado [ZSC]) that reserves most of the savannas for agricultural activities. Here, we outline how the methodology employed is flawed because it does not include fauna surveys, evaluations of ecosystem services or an assessment of the social importance of the savannas. The ZSC authors admit that, contrary to Brazilian legislation, the zoning was carried out with the single intention of increasing...
