A Palynological Atlas of the Amazon canga Vegetation [PDF]

Plants
cangas are iron-rich outcrops where rupestrian fields develop in the Carajás Mountain Range (CMR). canga formations are ancient ecosystems characterized by high levels of endemic and threatened plant species that thrive on iron-rich substrates in the ...

Plotting a future for Amazonian canga vegetation in a campo rupestre context

PLoS ONE, 2019
In order to establish effective conservation strategy, drivers of local and regional patterns of biodiversity need to be understood. The composition of local biodiversity is dependent on a number of factors including evolution and redistribution of ...

Long-term effects of a peer-led Brief Alcohol Screening and Intervention for College Students (BASICS) intervention to reduce alcohol consumption among Spanish university students: A 12-month randomised controlled trial. [PDF]

Addiction
Abstract Background and aims Harmful alcohol consumption remains widespread among university students and is associated with numerous academic, social and health‐related consequences. Peer‐led approaches offer a promising strategy to reduce risky drinking in this population.

Microclimate drives demographic compensation in a narrow endemic tropical species. [PDF]

New Phytol
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

Iron islands in the Amazon: investigating plant beta diversity of canga outcrops [PDF]

PhytoKeys, 2020
The world’s largest mineral iron province, Serra dos Carajás, is home to an open vegetation known as canga, found on top of isolated outcrops rising out of the Amazon rainforest. Over one thousand vascular plants species have been recorded in these canga

The Impact of Rhizospheric and Endophytic Bacteria on the Germination of Carajasia cangae: A Threatened Rubiaceae of the Amazon Cangas. [PDF]

Microorganisms
Carajasia cangae (Rubiaceae) is a narrow endemic species from the canga ecosystems of the Carajás National Forest that is facing extinction due to a limited range and habitat disturbance from hydroclimatological changes and mining activities. This study examines the influence of rhizospheric and endophytic bacteria on C.

Unraveling the herpetofauna diversity in canga and forest ecosystems of the Eastern Amazon. [PDF]

PLoS One
Species inventories are essential for discovering new taxa, improving knowledge of species’ geographic distributions, characterizing local richness, evaluating biodiversity loss, and contributing to the conservation of endangered areas, including those with endemic and rare species.

Size and isolation of naturally isolated habitats do not affect plant-bee interactions: A case study of ferruginous outcrops within the eastern Amazon forest

PLoS ONE, 2020
Pollination may be severely affected by the decreasing size and increasing isolation of habitat patches. However, most studies that have considered the effects of these two variables on plant-pollinator interactions have been carried out in areas that ...
