A cross-sectional survey was conducted at Polytechnic High School (PHS) to assess the spread of COVID-19 infection among students and staff. A random cluster sampling was conducted between May 19 and August 18, 2022, after the fourth wave of COVID-19 in Senegal. IgM and IgG SARS-CoV-2 antibodies were screened using WANTAI SARS-CoV-2 ELISA assays.

Ecological niche modeling (ENM) may be used to predict species seasonal distributions, but the resulting hypotheses should eventually be validated by field data. The painted lady butterfly () performs multigenerational migrations between Europe and Africa and has become a model species for insect movement ecology.

- The alfalfa weevil, native to the Western Palearctic, has two main mitochondrial clades (Western and Eastern/Egyptian) with limited understanding of native populations.
- The Western clade is heavily infected with the endosymbiotic bacteria Wolbachia, which affects genetic diversity and increases the fixation of mutations, while the Eastern clade shows a broader distribution.
- Research findings indicate geographic isolation due to historical ice ages shaped the clade differences, and using infected clade males for pest control in uninfected populations raises both potential benefits and concerns.
