Floodplains mostly consist of primary and secondary riverbeds, connecting channels and lakes that are either isolated from rivers and channels for most of the year, or lakes that are connected to rivers and channels for most (or all) of the year. We hypothesize that the differences in invertebrate communities, as calculated by beta-diversities, wil...
Atmospheric lead (Pb) concentrations in São Paulo city, Brazil, remain significant, despite the fact that leaded gasoline was phased out. The use of its isotope signature allows tracing emissions to the increasing number of cars, urban construction, and industrial emissions in this densely populated area. High-precision and accurate stable isotope ...
Natural regeneration offers a cheaper alternative to active reforestation and has the potential to become the predominant way of restoring degraded tropical landscapes at large‐scale. We conducted a meta‐analysis for tropical regions and quantified the relationships between both ecological and socioeconomic factors and biodiversity responses in nat...

Zika virus (ZIKV) was discovered in 1947 and was thought to lead to relatively mild disease. The recent explosive outbreak of ZIKV in South America has led to widespread concern, with reports of neurological sequelae ranging from Guillain Barré syndrome to microcephaly. ZIKV infection has occurred in areas previously exposed to dengue virus (DENV),...
SETTING: Greater Banjul and Upper River Regions, The Gambia. OBJECTIVE: To investigate tractable social, environmental and nutritional risk factors for childhood pneumonia. DESIGN: A case-control study examining the association of crowding, household air pollution (HAP) and nutritional factors with pneumonia was undertaken in children aged 2-59 mon...

Since its detection in Brazil in 2013, the Old World cotton bollworm Helicoverpa armigera has been reported in Argentina, Paraguay, and Bolivia. Here we present evidence extending the South American range of H. armigera to Uruguay, using polymerase chain reaction and sequencing of the partial mitochondrial DNA (mtDNA) cytochrome oxidase I region. M...
A diversidade de plantas cultivadas, selecionadas e conservadas pelos agricultores tradicionais, é de interesse tanto local quanto nacional, além de constituir um patrimônio biológico e cultural. No caso da Amazônia, apesar de atualmente dispormos de uma suma de dados sobre a agrobiodiversidade, a diversidade das opções metodológicas mobilizadas to...

ContextThe phenomenon of known as ‘land grabbing’ is not a new process. Especially, since the 1990s, some capital-rich countries have started to buy or lease foreign lands to be able to produce food and biofuels.ObjectivesThis article aimed at investigating the (un)sustainability of ‘transnational land deals’ (TLDs) for investors, host governments ...
The ectomycorrhizal milkcap genus Lactifluus is commonly found within Central and West African gallery forests. During field expeditions in Cameroon and Togo, several collections of white Lactifluus species were found, resembling Lactifluus foetens. Molecular and morphological research indicates that these collections belong to two unrelated specie...
