Article Synopsis
- Mammals are facing global threats, with about 26% of species in jeopardy due to habitat loss, pollution, and human actions, highlighting the need for conservation efforts.
- The "Mammals in Portugal" data set provides over 105,000 records of 92 mammal species across mainland Portugal and its islands from 1873 to 2021, primarily collected through live observations and sign surveys.
- It emphasizes the conservation status of various species, including those classified as threatened by the IUCN, and aims to support future research and conservation initiatives.
There is evidence that the CCR5-delta32 mutation confers protection against HIV-1 infection to homozygous individuals. It is believed that this mutation spread through Europe with the Vikings and that it has been subjected to positive selection, leading to a high frequency in Europe (approximately 10%). We carried out the present study to determine the 32-bp deletion allele and genotype frequencies of the CCR5 gene (CCR5-delta32) in the Atlantic island populations of Madeira, the Azores, Cabo Verde, and São Tomé e Principe.
