Seed dispersal by macaws shapes the landscape of an Amazonian ecosystem

open access: yesScientific Reports, 2017
Seed dispersal is one of the most studied plant–animal mutualisms. It has been proposed that the dispersal of many large-seeded plants from Neotropical forests was primarily conducted by extinct megafauna, and currently by livestock.

Environmental and Genetic Effects on the Composition of Palm Oil From Hybrid Plant Clones of Caiaué and Oil Palm

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The interspecific hybrids (IEH OxG) obtained from the crossing of Elaeis oleifera (Eo) and Elaeis guineensis (Eg) are resistant to some diseases that affect Eg in some regions of South America, and commercial growing in several countries has been established.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Açaí fruit production and carbon stock in managed plantations in Southeast of Roraima

open access: yesAgro@mbiente On-line, 2020
The quantification of the carbon stock present in fruits and residues from the manufacture of açaí pulp provides an estimate of the contribution of these key-species to the Amazonian ecosystem to maintain the Earth’s climatic balance.

Phenotypic, physicochemical, sensory, and functional attributes of cocoa (Theobroma cacao L.) from Brazilian Amazonian floodplain and upland ecosystems

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Cocoa (Theobroma cacao L.) from the Brazilian Amazon plays an important role in national production. While most cocoa is cultivated in upland systems, floodplain ecosystems represent a traditional and distinct production environment that may influence bean composition and quality.

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

open access: yesPeople and Nature, EarlyView.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.

Use of amazonian fruits in dental bleaching

open access: yesOBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA
Natural products stand out for their chemical diversity, thus plants are important candidates for screening new bioactive compounds. This study evaluated the effect of plant extracts combined with 16% carbamide peroxide (PC16%) on tooth whitening. Bovine teeth and composite resin blocks were randomly assigned to pigmentation and whitening protocols ...

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

open access: yesPeople and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.

What is ‘relational thinking’, and how does it manifest in research?

open access: yesPeople and Nature, EarlyView.
Abstract People and Nature is a ‘journal of relational thinking’. This editorial explores what relational thinking can mean and how it might be operationalized in the context of humans and the environment. Relational thinking may seem intuitive because it recognizes the world's inherent interconnectedness. However, the question of how to operationalize
