Constraints or Cooperation? Determinants of Secondary Forest Cover Under Shifting Cultivation
This study examines the drivers of land use in a shifting cultivation system with forest fallow. Forest fallow provides on-farm soil quality benefits, local hydrological regulation, and global public goods.

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil
Nordic Journal of Botany, EarlyView.In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Do Liquidity Constraints Help Preserve Tropical Forests? Evidence from the Eastern Amazon
This article examines the determinants of forest cover and land use efficiency in a shifting cultivation system. A conceptual model demonstrates that liquidity constraints encourage farmers to allocate more land to forest fallow and less to cultivation ...

Nonprofit Management and Leadership, EarlyView.ABSTRACT With the aim to explore the potential of machine learning for nonprofit research, this article contrasts traditional linear regression with four contemporary supervised machine learning approaches. Concretely, we predict (1) reputation ratings and (2) the total number of volunteers for 4021 non‐profit organizations in the U.S.

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory
Oikos, EarlyView.Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Degradation and deforestation increase the sensitivity of the Amazon Forest to climate extremes
Environmental Research LettersAbout 40% of the Brazilian Amazon has been deforested or suffered changes in forest structure through degradation (selective logging, fires, and fragmentation). The impact of forest degradation on the forest’s sensitivity to climate extremes has not been

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

Quantifying tropical forest rainfall generation
Communications Earth & EnvironmentTropical forests enhance regional rainfall but a robust analysis of this benefit is lacking. Consequently, the rainfall generating services of tropical forests are rarely accounted for in policymaking.
