Tapirs and large peccaries are key to ecological balance in Neotropical forests, study shows
Publicado em 26 janeiro 2022
Large mammals help keep a balance between areas with different levels of productivity in biomes like the Atlantic Rainforest, and regulate the spatial structure of plant communities. Credit: João Paulo Krajewski
A study conducted by researchers affiliated with São Paulo State University (UNESP) in Brazil shows that large mammals have a major impact on plant diversity, primary productivity and biomass in the understory of Neotropical forests. Species like the lowland tapir [...]

Studies show that tapirus and large peccaries are key to the ecological balance of Neotropical forests.
Publicado em 24 janeiro 2022Large mammals have a significant impact on plant diversity, primary productivity and biomass in understory vegetation in neotropical forests, according to a study conducted by researchers at the State University of São Paulo (UNESP) in Brazil. Species such as lowland tapirs (Tapirus terrestris) and white-lipped peccaries (Tayassu peccari) affect the spatial structure of plant communities while balancing the ecological balance of regions such as the Atlantic rainforest with different [...]ver notícia -
Studies show that conservation units use unreliable methods to monitor the presence of deer
Publicado em 19 janeiro 2022According to a survey of the management plans of 118 conservation units in Brazil, 60% use inappropriate methods to detect the presence of deer and 38% do not explain how they were used. As a result, the protection of these animals can be compromised. Eight species of deer live in Brazil. The three are red-listed as “vulnerable” by IUCN. The management plan defines the governance and technical aspects of the management of protected areas in Brazil. The Protected area The one [...]ver notícia -
Studies show that the gravitational effects of the sun and moon affect animal and plant behavior
Publicado em 05 janeiro 2022The rhythms of activity of all living things, both plants and animals, are closely related to the tides of gravity created by the orbital mechanics of the Sun-Earth-Moon system. This truth has been somewhat ignored by scientific research, but is foreground by studies by Cristiano de Melogalep at the University of Campinas (UNICAMP) in Sao Paulo, Brazil, and Daniel Robert at the University of Bristol in the United Kingdom.

Research shows how to convert waste into materials for advanced industries
Publicado em 08 dezembro 2021Worldwide, 118 million to 138 million tonnes of organic waste are generated annually, with waste from food production and distribution chains accounting for 100 million tonnes. Only about 25% of this bio waste is collected and recycled. The remaining 75% is simply abandoned, representing a huge loss of potential resources and great damage to the environment. These figures are from a report released in 2018 by the European Environment Agency. The statistics are up-to-date and are probably [...]ver notícia -
Modified proteins from rattlesnake venom enable the development of drugs that regulate blood coagulation
Publicado em 02 dezembro 2021Researchers in Brazil and Belgium have developed a molecule of interest in medicine from corinein-1, a protein found in rattlesnake venom. They used a technique called PEGylation to obtain drug candidates that make the molecule, now called PEG-rCollinein-1, more stable in vivo, resistant to the immune system, and regulate blood coagulation. .. An article reporting the results of the study was recently published International Journal of Biological Polymers.. “This technology is designed [...]ver notícia -
Environmental DNA sequencing allows scientists to explore Amazon’s fish diversity without catching fish.
Publicado em 23 novembro 2021Scientific expeditions in the Javary River basin on the border of Brazil, Colombia and Peru have shown that environmental DNA sequences can be used to investigate the diversity of Amazon fish. The eDNA method consists of extracting molecules of DNA present in a water sample and using genetic markers to identify the species to which they belong. Articles about research published in the journal Science report It also describes the limitations of methods for studying highly diverse environments [...]ver notícia -
Only one in four Western Roman emperors died of natural causes
Publicado em 15 outubro 2021The Roman Empire was ruled by 175 men, from Augustus (63 BCE-19 CE) to Constantine XI (1405-53), including the Eastern or Byzantine Empire after the split in 395 CE, but excluding those who did not rule in their own right because they were minors during regencies or co-emperors. Only 24.8% of the 69 rulers of the Western Empire died of natural causes. The rest died a violent death on the battlefield or in palace plots. Considering all 175, 30% were murdered, committed suicide or died in [...]ver notícia -

Publicado em 12 agosto 2021A team of scientists have discovered a new marmoset species in the Brazilian Amazon. Schneider’s Marmoset in the latest issue of the journal (Mico schneideri) Science report Named after Professor Oracio Schneider, a pioneer and major contributor to the study of monkey diversity and evolution. This discovery was made by a team of researchers currently led by Rodrigo Costa Araújo, a deputy researcher at Museu Paraense Emílio Goeldi. Araújo was partially funded by the [...]ver notícia -
Researchers are proposing ways to magnetize a material without applying an external magnetic field
Publicado em 29 julho 2021Magnetizing a material without applying an external magnetic field has been proposed in an article published in a journal by researchers at the State University of Sao Paulo (UNESP) in Brazil. Science report, Here we detail the experimental approach used to achieve this goal. This study was part of a PhD. A study pursued by Lucas Squillante under the supervision of Marianode Souza, a professor of physics at UNESP in Rio Claro. I also contributed another PhD, Isys Mello.
