This study, published in the journal Frontiers in Soil Science, introduces a promising avenue for sustainable biotech applications designed to combat land degradation. The research was conducted as part of FAPESP ‘s Biodiversity, Characterization, Conservation, Restoration, and Sustainable Use Program (BIOTA). Focus of thr study The researchers embarked on an in-depth exploration of Amazon dark earth, a soil type known for its nutrient richness and bustling community of [...]

Climate change is striking with a vengeance along the Brazilian coastline, particularly in the South and Southeast regions, resulting in extreme temperature events. The escalating severity of surface air temperatures and erratic switches from blistering heat to chilling cold are tangible evidence of this shift, as detailed in a recent study published in the journal Scientific Reports. A marked upswing in temperature extremes and heatwaves (defined as multiple consecutive [...]

The data was revealed in a study led by a Brazilian team of experts and published in the journal Scientific Reports. The shocking trend is not subtle. The last three years of the study period alone (2019-2021) have accounted for almost 60% of this emission, which can be attributed to the rapid acceleration of forest destruction. Emissions from ITs on the rise The researchers found that from 2013 to 2021, a total of 1,708 square kilometers (km²) were deforested in ITs, a figure that [...]

Between 450 BCE and 950 CE, Amerindian people living in today’s Amazonia fundamentally transformed their habitat’s originally poor soils, enriching them with charcoal from their low-intensity fires used for cooking and burning refuse, as well as from manure, animal bones, broken pottery, and compost. The result is the exceptionally fertile Amazonian dark earth (ADE) – “tera preta” – which is rich in nutrients and stable organic matter derived from charcoal [...]

For a long time, scientists have used to associate dogs’ aggressiveness solely with breed. However, a paradigm shift has occurred over the past decade, due to research linking behavioral profiles to factors such as dogs’ sex, age, metabolism, and hormonal patterns.  Now, based on a survey of 665 dog owners detailing the physical and behavioral features of their pet dogs, a team of researchers led by the University of São Paulo (USP) in Brazil has [...]

Capuchin monkeys are among only a few species of primates that use tools in their daily activities. For instance, they use stones as hammers and anvils to crack open cashew nuts and other hard foods. Although scientists have long thought that tool size correlates with food hardness, a new study led by the University of São Paulo has found that this is not always the case. By observing three populations of bearded capuchin monkeys (Sapajus libidinosus), and measuring food hardness, [...]

The Tiger Beach in Bahamas is famous not only for its pristine beauty, but also for being frequented by an animal that might scare some people, but is in fact a major tourist attraction: the Tiger shark (Galeocerdo cuvier). Since the sea is crystal clear and only five meters deep, the sharks – which often surpass three meters in length – can be seen easily, and are often drawn to the site by local tour operators who throw fish and other food in the water. Now, a team of [...]

The release of carbon caused by degradation in the Atlantic Rainforest could result in emissions that are more than 30 percent higher than those associated with climate change. This is the conclusion of a recent study published in the journal Science Advances, which clarifies carbon sequestration in the Atlantic Rainforest.  “We still know little about the factors that can lead forests to store more or less carbon,” said study co-author Renato Augusto [...]

Bullfrogs are considered the world’s leading invasive amphibian. The American bullfrog (Aquarana catesbeiana) is native to North America and was first brought to Rio de Janeiro in Brazil in 1935 to produce meat. Now, it is farmed throughout the South and Southeast of Brazil, but has also spread into the wild, negatively impacting local ecosystems by competing with native species for food and other resources, feeding on other frogs, as well as snakes, birds, and even some [...]
