“…In the G. pseudogeographica species complex, of interest for us, a G. geographica X G. ouachitensis F1 hybrid female was apparently sterile (Vogt 2018) and there appears to be a decrease in fitness in G. geographica X G. pseudogeographica hybrid females (Freedberg and Myers 2012;Mitchell et al 2016), but there is no indication (so far) for any incompatibility between G. pseudogeographica and G. ouachitensis (Freedberg and Myers 2012;Vogt 2018 but also in Ploiești and Piteşti (Iftime and Iftime, pers. obs., 2020 -Fig.…”

The paper presents a review of literature data, supplemented with original observations, on the presence, establishment, distribution and invasive status of alien fish, amphibian and reptile species in Romania. Consistent criteria were followed in defining alien species records, establishment and invasive status. From the 48 alien fish species, 1 fish hybrid, 1 amphibian and 18 reptile species recorded, only 16 fishes and 3 reptiles can be regarded as established. Of these we consider the criteria for invasive status as being probably fulfilled by one fish species (Perccottus glenii), and less likely by six more fish species. The presence and the alien status of the one amphibian are debatable. No reptile species can be considered invasive at present.

“…Despite these variations, recent studies suggest that hybridization is frequently observed in contact zones (Jiggins et al, 1996;Mallet, 2005). The genetic introgression can differentially involve mitochondrial and nuclear genomes (Dufresnes et al, 2015;Mitchell, Muehlbauer & Freedberg, 2016). Furthermore, genetic introgression can be asymmetric and occur preferentially in one of the two species in contact (Mallet, 2005;Dufresnes et al, 2015Dufresnes et al, , 2016.…”

“…In order to better understand parapatric distribution, it appears critical to focus on contact zones to examine possible hybridizations and genetic introgressions (Dufresnes et al, 2015). In this context, both mitochondrial and nuclear markers provide useful tools to detect potential barriers between species or quantify the amount and directionality of gene flow (Mitchell et al, 2016).…”

Western European vipers are well‐defined species with parapatric distributions that reflect contrasting thermal niches and climatic adaptations. Contact zones are usually narrow, coincide with steep ecological gradients and are associated with clear habitat segregation. Natural hybridization has been demonstrated between several species but has not been detected in others. The cold‐adapted adder (V. berus, subgenus Pelias) is not known to hybridize with the warm‐adapted aspic viper (V. aspis subgenus Vipera). For over 12 years, we have monitored sympatric populations of V. berus and V. aspis in western France where the two species exhibit very similar life cycles. We tested for possible hybridization because individuals with intermediate morphological traits have been reported in the past and were recently detected in the study population. Our results demonstrate that hybridization actually occurs and is directional since it involves females V. aspis viper and male V. berus in all analyzed cases. We discuss our results in the frame of previous findings on contact zones to evaluate in which conditions hybridization may occur.

“…With faster evolutionary rates, mitogenes are advantageous for studying relationships of crown groups, while nuclear genes offer abundant information in resolving relationships of deeper clades of a tree. Phylogenetic relationships inferred from nuclear DNA might be bias for taxa in which introgressive hybridization is common [ 70 ], while such interference decreases in mitogenomes if it is restricted to male introgression [ 71 ]. Secondly, different mitogenes can be discrepant in resolving relationships of species, for evolutionary rate varied through the whole mitogenome.…”

The lineage of the Bar-backed Partridge (Arborophila brunneopectus) was investigated to determine the phylogenetic relationships within Arborophila as the species is centrally distributed within an area covered by the distributions of 22 South-east Asian hill partridge species. The complete mitochondrial genome (mitogenome) of A. brunneopectus was determined and compared with four other hill partridge species mitogenomes. NADH subunit genes are radical in hill partridge mitogenomes and contain the most potential positive selective sites around where variable sites are abundant. Together with 44 other mitogenomes of closely related species, we reconstructed highly resolved phylogenetic trees using maximum likelihood (ML) and Bayesian inference (BI) analyses and calculated the divergence and dispersal history of Arborophila using combined datasets composed of their 13-protein coding sequences. Arborophila is reportedly be the oldest group in Phasianidae whose ancestors probably originated in Asia. A. rufipectus shares a closer relationship with A. ardens and A. brunneopectus compared to A. gingica and A. rufogularis, and such relationships were supported and profiled by NADH dehydrogenase subunit 5 (ND5). The intragenus divergence of all five Arborophila species occurred in the Miocene (16.84~5.69 Mya) when there were periods of climate cooling. We propose that these cooling events in the Miocene forced hill partridges from higher to lower altitudes, which led to geographic isolation and speciation. We demonstrated that the apparently deleterious +1 frameshift mutation in NADH dehydrogenase subunit 3 (ND3) found in all Arborophila is an ancient trait that has been eliminated in some younger lineages, such as Passeriformes. It is unclear of the biological advantages of this elimination for the relevant taxa and this requires further investigation.
