Multi-Taxa Responses to Climate Change in the Amazon Forest.
Glob Chang Biol
November 2024
Departamento de Biologia, Universidade Federal Do Amazonas, Manaus, Brazil.
Article Synopsis
- Tropical biodiversity is facing significant changes due to intensified hydrological cycles, resulting in more severe droughts and wet seasons, which raises concerns about the resilience of ecosystems.
- A 20-year study in Central Amazonia assessed the impacts of these climate changes on bird, fish, ant, and palm communities, revealing distinct responses where animals were more affected by sudden climate extremes, while palm species showed more stability over time.
- The research indicated that while the 'insurance effect' helped moderate long-term impacts of climate events on biodiversity, the anticipated 'environmental refugia' did not effectively protect species during extreme weather conditions, highlighting the complex resilience of ecosystems amidst climate change.
Developing remote patient monitoring infrastructure using commercially available cloud platforms.

David Geffen UCLA School of Medicine, University of California Los Angeles, Los Angeles, CA, United States.
Wearable sensor devices for continuous patient monitoring produce a large volume of data, necessitating scalable infrastructures for efficient data processing, management and security, especially concerning Patient Health Information (PHI). Adherence to the Health Insurance Portability and Accountability Act (HIPAA), a legislation that mandates developers and healthcare providers to uphold a set of standards for safeguarding patients' health information and privacy, further complicates the development of remote patient monitoring within healthcare ecosystems. This paper presents an Internet of Things (IoT) architecture designed for the healthcare sector, utilizing commercial cloud platforms like Microsoft Azure and Amazon Web Services (AWS) to develop HIPAA-compliant health monitoring systems.

October 2024
Laboratório de Ecologia, Faculdade de Ciências Biológicas, Universidade Federal do Pará, Altamira, PA, 68371970, Brasil.
In Brazil, there is 13% of the world's bat diversity, is the second most diverse group of mammals, playing a crucial role in providing ecosystem services that benefit humans. However, anthropogenic disturbances exacerbate processes of species extinction, shifts in geographic distributions, and phenological changes, despite efforts to safeguard biodiversity through the creation of Conservation Units and Indigenous Lands. Moreover, gaps in taxonomic knowledge and challenges related to species distribution hinder the effective implementation of conservation strategies in protected areas.

Adapted Sequential Extraction Protocol to Study Mercury Speciation in Gold Mining Tailings: Implications for Environmental Contamination in the Amazon.
Toxics
April 2024
Institute of Chemistry, University of Brasília, Asa Norte, Brasilia 70910-900, Brazil.
Artisanal small-scale gold mining (ASGM), an increasingly prevalent activity in South America, generates mercury-contaminated tailings that are often disposed of in the environment, leading to the introduction of mercury into ecosystems and the food web, where it bioaccumulates. Therefore, studying the geochemical processes involved in the desorption and dissolution of mercury in these tailings is essential for critical risk evaluations in the short and long term. For this purpose, sequential extraction procedures (SEPs) can be useful because they help to identify the phases to which Hg is associated, although they also have limitations such as a lack of selectivity and specificity.
