- Glyphosate in the Iberian Peninsula: Evaluating risks to Iberian wildlifePublication . Baptista, Catarina Jota; Marques, Gonçalo Nogueira; Gonçalves, Luísa Lima; Assunção, Ricardo; Martinez-Haro, MónicaGlyphosate [N-(phosphonomethyl)glycine] (GlyP) is an herbicide extensively used worldwide, including the Iberian Peninsula. It is mainly used in agricultural landscapes but also in urban areas, in railways, and even in water bodies. Despite glyphosate’s large use, there is a paucity of research on its exposure and its potential effects on wildlife living treated environments. In recent years, an increasing number of studies have warned about the effects of this herbicide namely, on oxidative stress, and on liver and kidney in different taxa. Additionally, some studies also suggested endocrine disruption capacity in reptiles or genotoxicity in fish. Most of these studies have been carried out on experimental animals, in laboratory conditions, so the real exposure and potential effects on wildlife is largely unknown. In this context, this review is intended to help understand the ecological consequences that glyphosate may be exerting on wildlife that inhabit the Iberian Peninsula.
- Wolbachia Screening in Aedes aegypti and Culex pipiens Mosquitoes from Madeira Island, PortugalPublication . Fernandes, Rita; Melo, Tiago; Marques Zé-Zé, Líbia Maria; Campos Freitas, Inês; Silva, Manuel; Dias, Eva; Santos, Nuno C.; Gouveia, Bruna R.; Seixas, Gonçalo; Costa Osório, HugoSimple Summary: Mosquitoes can spread serious diseases like dengue and West Nile virus. On Madeira Island, two mosquito species—Aedes aegypti and Culex pipiens—are present and may pose a risk to public health. Scientists are exploring new ways to control these mosquitoes using a natural bacterium called Wolbachia, which can reduce a mosquito’s ability to transmit viruses and even lower mosquito populations. However, for these methods to work, it is important to know first if the mosquitoes in the area already carry this bacterium. In this study, we tested Ae. aegypti and Cx. pipiens from Madeira for Wolbachia. Wolbachia was absent in all 100 Ae. aegypti tested but present in all 40 Cx. pipiens. We also found that the Wolbachia in Cx. pipiens belonged to a group commonly seen in other parts of the world. These results are important because they help us understand which mosquito control strategies might work in Madeira. Specifically, if scientists want to use Wolbachia to control Ae. aegypti on the island, they would need to introduce it artificially. This information can help improve public health efforts and reduce the risk of mosquito-borne diseases in the region.
