“…Além disso, o cálculo do tempo de divergência mostrou que a separação entre as populações brasileiras e africanas ocorreu por volta de 200 mil anos, confirmando que P. perna não seria uma espécie exótica no Brasil. Apesar disso, tal situação mostra-se singular, pois é considerada uma EEIs pela legislação de dois estados (Paraná e Rio Grande do Sul), bem como uma espécie ameaçada no Estado de Santa Catarina, onde tem sua produção comercial comprometida por competição com o molusco bivalve Mytilus galloprovincialis Lamarck, 1819, que é original do Mediterrâneo (Belz et al, 2020, Lins et al, 2021, mas que ainda não consta na lista oficial de SC. Da mesma forma, outra ame-aça próxima é a espécie Perna viridis (Linnaeus, 1758), um mexilhão nativo do Oceano Indo-Pacífico e já registrado no Rio de Janeiro (Messano et al, 2019).…”

As espécies exóticas invasoras (EEIs) marinhas têm mostrado crescente impacto em diversas regiões do mundo, o que é potencializado em regiões ocupadas por grandes em-preendimentos portuários. De acordo com o presente levantamento, realizado em 2021/22, os registros de EEIs em listas oficiais no sul do Brasil totalizam 28 espécies de animais mari-nhos, o que representa cerca de 40% do número de animais marinhos exóticos invasores registrados no país. Os crustáceos são o grupo taxonômico com maior número de EEI mari-nhas, tanto no Sul como em todo o litoral brasileiro. O ICMBio e MMA têm instituído guias de orientação ao manejo e programas nacionais que buscam a detecção precoce e a resposta rápida às espécies exóticas invasoras. Estas são iniciativas fundamentais para mitigar im-pactos sobre a biodiversidade brasileira.

“…Invasive M. galloprovincialis threaten regional-scale genetic diversity in the mainland and remote offshore locations in the Southern Ocean [ 170 , 171 , 172 ]. This species recently invaded the Atlantic coasts of South America [ 173 , 174 ]. A significant differentiation of M. chilensis natural and cultured populations in the wild (Reloncavi, an inner bay influenced by aquaculture; Chiloe Island outer bay, and Patagonia, the most distinct population) was also delineated using neutral and outlier SNPs [ 175 ].…”

An increasing number of aquatic species have been studied for genetic polymorphism, which extends the knowledge on their natural populations. One type of high-resolution molecular marker suitable for studying the genetic diversity of large numbers of individuals is single nucleotide polymorphism (SNP). This review is an attempt to show the range of applications of SNPs in studies of natural populations of aquatic animals. In recent years, SNPs have been used in the genetic analysis of wild and enhanced fish and invertebrate populations in natural habitats, exploited migratory species in the oceans, migratory anadromous and freshwater fish and demersal species. SNPs have been used for the identification of species and their hybrids in natural environments, to study the genetic consequences of restocking for conservation purposes and the negative effects on natural populations of fish accidentally escaping from culture. SNPs are very useful for identifying genomic regions correlated with phenotypic variants relevant for wildlife protection, management and aquaculture. Experimental size-selective catches of populations created in tanks have caused evolutionary changes in life cycles of fishes. The research results have been discussed to clarify whether the fish populations in natural conditions can undergo changes due to selective harvesting targeting the fastest-growing fishes.

“…All individuals were genotyped with a panel of 54 SNPs that have shown good genotyping performance and reproducibility (Lins et al, 2021;Wenne et al, 2020;Zbawicka et al, 2012Zbawicka et al, , 2014Zbawicka et al, , 2018Zbawicka et al, , 2019, using the Sequenom MassARRAY iPLEX genotyping platform (Gabriel et al, 2009). Three Individuals showed a genotyping rate of less than 90%, therefore, 160 individuals were kept for further analysis (Table 1).…”

“…The other five are native to the northern hemisphere ( M. californianus , M. edulis , M. galloprovincialis , M. trossulus and M. unguiculatus ) (Gardner et al., 2021; Yang et al., 2021). However, M. galloprovincialis is also widespread around the world, being listed as a highly invasive species in regions such as California, South Africa, China, New Zealand, Australia, Chile, Argentina and Brazil (Braby & Somero, 2006; Branch & Steffani, 2004; Lins et al., 2021; Oyarzún et al., 2016; Pickett & David, 2018; Seo & Lee, 2009; Tarifeño et al., 2012; Zbawicka et al., 2018, 2022).…”

Hybrid zones among mussel species have been extensively studied in the northern hemisphere. In South America, it has only recently become possible to study the natural hybrid zones, due to the clarification of the taxonomy of native mussels of the Mytilus genus. Analysing 54 SNP markers, we show the genetic species composition and admixture in the hybrid zone between M. chilensis and M. platensis in the southern end of South America. Bayesian, non‐Bayesian clustering and re‐assignment algorithms showed that the natural hybrid zone between M. chilensis and M. platensis in the Strait of Magellan, Isla Grande de Tierra del Fuego and the Falkland Islands shows clinal architecture. The hybrid zone can be divided into three different areas: the first one is on the Atlantic coast where only pure M. platensis and hybrid were found. In the second one, inside the Strait of Magellan, pure individuals of both species and mussels with variable degrees of hybridisation coexist. In the last area at the Strait in front of Punta Arenas City, fjords on the Isla Grande de Tierra del Fuego, and at the Beagle Channel, only M. chilensis and a low number of hybrids were found. According to the proportion of hybrids, bays with protected conditions away from strong currents would give better conditions for hybridisation. We do not find evidence of any other mussel species such as M. edulis, M. galloprovincialis, M. planulatus or M. trossulus in the zone.
