Ensuring Pollinator Presence in Expanding Oil Crops: The Case of Mystrops debilis (Nitidulidae) and the Macauba Palm (Acrocomia aculeata, Arecaceae)

open access: yesJournal of Applied Entomology, Volume 149, Issue 8, Page 1180-1195, September 2025.
ABSTRACT The macauba palm (Acrocomia aculeata, Arecaceae) is a Neotropical native oil palm, increasingly important in Central and South America due to rising demand for raw materials and its potential for bioenergy. Understanding its pollinator ecology is crucial to identify new areas for cultivation. This study examines the structure of floral visitor

Adequação dos parâmetros do modelo de Green-Ampt-Mein-Larson em condições de campo Adjustment of Green-Ampt-Mein-Larson model parameters under field conditions

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2010
O modelo de Green-Ampt-Mein-Larson (GAML) é um dos mais empregados na modelagem da infiltração; entretanto, alguns de seus parâmetros não condizem com a situação real do processo de infiltração da água no solo.

Climate and Fire Outweigh the Role of Soil as Drivers of Plant Community Assembly in Tropical Grasslands

open access: yesJournal of Vegetation Science, Volume 36, Issue 5, September/October 2025.
We investigated the relative influences of environmental factors and fire history on the composition, diversity, and structure of Cerrado grassland plant communities. We found minimum temperature and fire frequency significantly correlated with the floristic similarity between sites.

Opportunities, research gaps, and risks in allogenic ecosystem engineer mimicry

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract In an age of anthropogenically driven species loss and increasingly novel ecosystems, ecosystem engineer restoration is a process‐based approach to supporting ecosystem function. Many ecosystem engineers have low or declining population sizes.

Environmental impacts of a reduced flow stretch on hydropower plants

open access: yesBrazilian Journal of Biology, 2018
In Brazil, given its privileged hydrology, the unexplored economic use of water resources has many dimensions, such as hydroelectric power. This energy will face increasingly rigorous social and environmental impact assessments (40% of potential is ...

Effects of Hydrological and Catchment Biophysical Factors on Baseflow Dynamics in Two Neighbouring Micro‐Catchments of the Andean Ecosystems

open access: yesHydrological Processes, Volume 39, Issue 7, July 2025.
While the convergence of the flow duration curve indicates similar behaviour as baseflow decreases, Shigual can sustain slightly higher minimum flows during extremely dry periods compared to Anduy. The mean baseflow indices of both catchments are similar, but Anduy faced a sharp baseflow recession, whereas Shigual exhibited a more stable baseflow ...
