Microbial drivers of root plasticity

New Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Biases in Amphibian Sampling in the Amazon: Using Infrastructure and Accessibility Data to Identify Sampling Gaps

Biotropica, Volume 57, Issue 5, September 2025.
Biogeographic knowledge of Amazonian amphibians is constrained by spatial and temporal coverage, leading to biases that affect the understanding of their diversity patterns. Using an extensive occurrence database, this study identified knowledge gaps and sampling biases linked to infrastructure and accessibility factors across the region.

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

Remote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 394-410, August 2025.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

Experimental Drought Suppresses Amphibian Pathogen Yet Intensifies Transmission and Disrupts Protective Skin Microbiome

Global Change Biology, Volume 31, Issue 6, June 2025.
This study used ecologically realistic enclosures with pumpkin toadlets to simulate short‐term drought conditions in Brazil's Atlantic Forest. Drought reduced the overall levels of a harmful amphibian fungus, but it also disrupted their protective skin‐associated bacteria and caused the toadlets to cluster in wet areas of the enclosures, which ...

Complex and Dynamic Effects of an Extreme Low Temperature Weather Event on Invasive Plant Populations and Resident Communities

Global Change Biology, Volume 31, Issue 3, March 2025.
Invasive plant species might benefit more from climate change, though evidence for that is not clear. Here, we show that the effects of a low‐temperature extreme weather event can result in a dramatic reduction in both vegetative and reproductive growth of invasive populations of Gunnera tinctoria (giant rhubarb) in the west of Ireland.

Prioridade: construir o capital social

Revista Espaço Acadêmico, 2019
O fracasso das recomendações do ”Consenso de Washington” – liberalizar, privatizar e flexibilizar as relações de trabalho – impõe uma revisão urgente da teoria e da prática do desenvolvimento econômico.

CRESCIMENTO E DESENVOLVIMENTO DE LÍNGUA-DE-VACA

Colloquium Agrariae, 2020
A língua-de-vaca é uma planta daninha perene, que infesta principalmente pastagens, lavouras anuais e perenes na região Sul do Brasil. Por ser uma planta perene, o controle se torna mais difícil devido ao rebrote. O trabalho teve como objetivo acompanhar

A multidisciplinary overview on the Tupi‐speaking people expansion

American Journal of Biological Anthropology, Volume 186, Issue 1, January 2025.
Expansion of Tupi linguistic subfamilies. Abstract The cultural and biological diversity of South American indigenous groups represent extremes of human variability, exhibiting one of the highest linguistic diversities alongside a remarkably low within‐population genetic variation and an extremely high inter‐population genetic differentiation.

Establishing a Marine Protected Area network using a Marine Spatial Planning approach: A reflection on practical challenges and opportunities for social–ecological integration

Conservation Science and Practice, Volume 6, Issue 10, October 2024.
Often, the establishment of Marine Protected Areas (MPAs) and the application of Marine Spatial Planning (MSP) occur in parallel. Using São Tomé and Príncipe as a case study, we illustrate how MSP was employed as an operational framework for establishing an MPA network.
