Cold waves in the Amazon rainforest and their ecological impact.

Cold waves crossing the Amazon rainforest are an extraordinary phenomenon likely to be affected by climate change. We here describe an extensive cold wave that occurred in June 2023 in Amazonian-Andean forests and compare environmental temperatures to experimentally measured thermal tolerances and their impact on lowland animal communities (insects and wild mammals). While we found strong reductions in activity abundance of all animal groups under the cold wave, tropical lowland animals showed thermal tolerance limits below the lowest environmental temperatures measured during the cold wave.

Newspaper Coverage and Framing of Bats, and Their Impact on Readership Engagement.

The media is a valuable pathway for transforming people's attitudes towards conservation issues. Understanding how bats are framed in the media is hence essential for bat conservation, particularly considering the recent fearmongering and misinformation about the risks posed by bats. We reviewed bat-related articles published online no later than 2019 (before the recent COVID19 pandemic), in 15 newspapers from the five most populated countries in Western Europe.

Utility of a commercial immunoblot kit (BAG-Borrelia blot) in the diagnosis of the preliminary stages of Lyme disease.

The aim of this study was to evaluate the usefulness of a commercial immunoblot (IgG and IgM BAG-Borrelia blot) in the serologic diagnosis of the early stages of Lyme disease. A total of 42 sera from patients with Lyme disease (24 patients with localized early stage (LES) and 18 patients with disseminated early stage (DES)) and 129 sera from patients with non-Lyme diseases (specificity control sera) were studied. IgG anti-p41 from Borrelia burgdorferi s.
