Whole-genome SNP genotyping unveils ancestral and recent introgression in wild and domestic goats.

After the domestication of goats around 10,000 years before the present (BP), humans transported goats far beyond the range of their wild ancestor, the bezoar goat. This brought domestic goats into contact with many wild goat species such as ibex and markhor, enabling introgression between domestic and wild goats. To investigate this, while shedding light on the taxonomic status of wild and domestic goats, we analysed genome-wide SNP data of 613 specimens from 14 taxonomic units, including Capra hircus, C.

Diversification within an oceanic Mediterranean island: Insights from a terrestrial isopod.

Understanding intra-island patterns of evolutionary divergence, including cases of cryptic diversity, is a crucial step towards deciphering speciation processes. Cyprus is an oceanic island isolated for at least 5.3 Mya from surrounding continental regions, while it remains unclear whether it was ever connected to the mainland, even during the Messinian Salinity Crisis.

High-throughput degraded DNA sequencing of subfossil shells of a critically endangered stenoendemic land snail in the Aegean.

High-throughput sequencing has enabled the comprehensive genetic exploration of biological diversity, especially by using natural history collections to study hard-to-find, threatened or even extinct-in-the-wild taxa. Mollusk shells are under-exploited as a source for DNA-based approaches, despite their apparent advantages in the field of conservation genetics. More particularly, degraded DNA techniques combined with high-throughput sequencing have never been used to gain insights about the DNA preservation in land snail subfossil or historical shells.

The Galapagos giant tortoise Chelonoidis phantasticus is not extinct.

The status of the Fernandina Island Galapagos giant tortoise (Chelonoidis phantasticus) has been a mystery, with the species known from a single specimen collected in 1906. The discovery in 2019 of a female tortoise living on the island provided the opportunity to determine if the species lives on. By sequencing the genomes of both individuals and comparing them to all living species of Galapagos giant tortoises, here we show that the two known Fernandina tortoises are from the same lineage and distinct from all others.

A new lineage of Galapagos giant tortoises identified from museum samples.

The Galapagos Archipelago is recognized as a natural laboratory for studying evolutionary processes. San Cristóbal was one of the first islands colonized by tortoises, which radiated from there across the archipelago to inhabit 10 islands. Here, we sequenced the mitochondrial control region from six historical giant tortoises from San Cristóbal (five long deceased individuals found in a cave and one found alive during an expedition in 1906) and discovered that the five from the cave are from a clade that is distinct among known Galapagos giant tortoises but closely related to the species from Española and Pinta Islands.

Population Genomics of Wall Lizards Reflects the Dynamic History of the Mediterranean Basin.

The Mediterranean Basin has experienced extensive change in geology and climate over the past six million years. Yet, the relative importance of key geological events for the distribution and genetic structure of the Mediterranean fauna remains poorly understood. Here, we use population genomic and phylogenomic analyses to establish the evolutionary history and genetic structure of common wall lizards (Podarcis muralis).

Molecular identification and geographic origin of a post-Medieval elephant finding from southwestern Portugal using high-throughput sequencing.

Molecular species identification plays a crucial role in archaeology and palaeontology, especially when diagnostic morphological characters are unavailable. Molecular markers have been used in forensic science to trace the geographic origin of wildlife products, such as ivory. So far, only a few studies have applied genetic methods to both identify the species and circumscribe the provenance of historic wildlife trade material.

A contribution to knowledge on the terrestrial malacofauna of the Kastellorizo (Megisti) island group (SE Greece).

Background: The Kastellorizo island group (in the Dodecanese, Greece) is situated in the southeast corner of the Aegean Archipelago. It consists of twenty islets, of which the three largest (Kastellorizo, Ro and Strongyli) and seven smaller ones belong to Greece. Knowledge of the malacofauna on the islands is relatively poor.

Promoting evolution: the brand new .

Herein we present the recently founded Hellenic Evolutionary Society (HEVOS) that has been recently instituted to promote evolution and scientific thinking among the Greek-speaking public. HEVOS is a timely initiative, given the low levels of acceptance of evolution by Greek society and the almost complete lack of evolution teaching in primary and secondary education in Greece. Herein, the main aims of the Society are presented.

Multigene phylogeny, phylogeography and population structure of Podarcis cretensis species group in south Balkans.

The evolutionary history of taxa with limited overseas dispersal abilities is considered to be majorly influenced by vicariant events constituting them as model organisms for the interpretation of evolutionary processes. An excellent candidate are the wall lizards of the genus Podarcis exhibiting an impressive level of genetic and morphological diversification and harboring several cases of recently discovered cryptic diversity. In this study, we investigated the effect of palaeogeographic events on the wall lizards' biodiversity patterns in the Aegean (Greece) as well as the evolutionary processes that acted both in space and time.

Giant tortoise genomes provide insights into longevity and age-related disease.

Giant tortoises are among the longest-lived vertebrate animals and, as such, provide an excellent model to study traits like longevity and age-related diseases. However, genomic and molecular evolutionary information on giant tortoises is scarce. Here, we describe a global analysis of the genomes of Lonesome George-the iconic last member of Chelonoidis abingdonii-and the Aldabra giant tortoise (Aldabrachelys gigantea).

Theory, practice, and conservation in the age of genomics: The Galápagos giant tortoise as a case study.

High-throughput DNA sequencing allows efficient discovery of thousands of single nucleotide polymorphisms (SNPs) in nonmodel species. Population genetic theory predicts that this large number of independent markers should provide detailed insights into population structure, even when only a few individuals are sampled. Still, sampling design can have a strong impact on such inferences.

Multilocus phylogeny and coalescent species delimitation in Kotschy's gecko, Mediodactylus kotschyi: Hidden diversity and cryptic species.

Kotschy's Gecko, Mediodactylus kotschyi, is a small gecko native to southeastern Europe and the Levant. It displays great morphological variation with a large number of morphologically recognized subspecies. However, it has been suggested that it constitutes a species complex of several yet unrecognized species.

Identification of wild-caught phlebotomine sand flies from Crete and Cyprus using DNA barcoding.

Background: Phlebotomine sand flies (Diptera: Psychodidae) are vectors of Leishmania spp., protozoan parasites responsible for a group of neglected diseases called leishmaniases. Two sand fly genera, Phlebotomus and Sergentomyia, contain species that are present in the Mediterranean islands of Crete and Cyprus where the visceral (VL), cutaneous (CL) and canine (CanLei) leishmaniases are a public health concern.
