Uncovered genetic diversity in Hemidactylus mabouia (Reptilia: Gekkonidae) from Madeira Island reveals uncertain sources of introduction

Hemidactylus mabouia is one of the most widely distributed species within its genus. It was first reported to Madeira in 2002 and the first individuals were considered to have originated from Cape Verde. Almost 20 years later, we found that H. mabouia has substantially expanded its distribution and can now be found >10 km away from Funchal, where it was first reported. Based on a 12S phylogenetic analysis and using 29 individuals from Funchal and Câmara de Lobos we found that Madeira actually harbours two distinct lineages of H. mabouia: one exclusively South American and another widespread in America and Africa. However, the lack of genetic diversity typical of this species outside its native range and the obtained phylogenetic pattern prevent us to infer possible introduction routes or sources. Our study emphasizes that authorities should remain vigilant regarding the arrival of other non-natives and act to prevent their establishment as soon as they are detected.

Phylogenetic pattern of SARS-CoV-2 from COVID-19 patients from Bosnia and Herzegovina: lessons learned to optimize future molecular and epidemiological approaches

This is the first report of molecular and epidemiology findings from Bosnia and Herzegovina related to ongoing SARS-CoV-2 epidemic. Whole Genome Sequence of four samples from COVID-19 outbreaks was done in two laboratories in Bosnia and Herzegovina (Veterinary Faculty Sarajevo and Alea Genetic Center). All four BiH sequences cluster mainly with European ones (Italy, Austria, France, Sweden, Cyprus, England). The constructed phylogenetic tree indicates possible multiple independent introduction events. The data presented contributes to a better understanding of COVID-19 in the current reemergence of the disease.

All four BiH sequences cluster mainly with European ones (Italy, Austria, France, Sweden, Cyprus, England). The constructed phylogenetic tree indicates probable multiple independent introduction events. The success of future containment measures concernig new introductions will be highly challenging for country due to the significant proportion of BH population living abroad.

Mitogenome Diversity and Maternal Origins of Guangxi Buffalo Breeds

Guangxi Province, in the southwest of China, is one of the putative migratory corridors or domestication centers for swamp buffalo. In this study, we investigated the evolutionary status of two Guangxi native buffalo breeds (Fuzhong buffalo, n = 15; Xilin buffalo, n = 25) based on the complete mitogenome sequencing. Our results revealed rich genetic diversity in the two buffalo breeds. We detected five haplogroups (SA1, SA2, SB1, SB2, SB3) in the two Guangxi buffalo breeds, and the haplogroup SB3 in the Fuzhong buffalo. Our results showed that the haplogroup SA1 was associated with the major domestication event that involved population expansion in Guangxi buffalo. In conclusion, our findings revealed a high level of maternal genetic diversity and the phylogenetic pattern of the two Guangxi buffalo breeds.
