Long‐term within‐basin isolation patterns, different conservation units, and interspecific mitochondrial DNA introgression in an amphipod endemic to the ancient Lake Skadar system, Balkan Peninsula

1. Investigation of biodiversity, including genetic diversity within species, is crucial for rational planning of nature conservation and species protection. Endemics or narrow-ranged taxa, sensitive to alteration of physical and chemical conditions, may serve as local bioindicators. 2.Homoeogammarus scutarensis is an endemic, cold-adapted amphipod crustacean, inhabiting fragmented spring habitats, within a relatively small area of the Lake Skadar basin. The basin is recently under heavy anthropogenic influence leading to habitat deterioration.3. Genetic diversity within H. scutarensis was investigated using the mitochondrial cytochrome c oxidase subunit I and the nuclear 28S ribosomal RNA markers.Genetic diversity within the mitochondrial (mt)DNA appeared to be surprisingly high as for the limited spatial scale. The history of within-species divergence dates back at least to the Pliocene. 4. A case of interspecific mtDNA introgression from the endemic H. scutarensis to the widespread and partly sympatric Homoeogammarus thoni was observed in one of the studied populations. Demographic analysis showed that the demography of H. scutarensis population hasbeen stable, without evidence of expansion. Thus, we believe that H. scutarensis, responsive to environmental changes, is a proper model mirroring the conditions in sensitive habitats of the Lake Skadar basin. To protect ongoing evolutionary processes, the conservation measures for this species should take into account the complex fine-scale lineage endemism patterns. This case study may also provide a hint for planning conservation strategies in other geologically old spring systems.6. Most of the localities where H. scutarensis occurs provide refugia for divergent mtDNA lineages, suggesting prolonged isolation between sites and independent evolutionary histories. We conclude that H. scutarensis is composed of two or three conservation units. One of them occupies the headwaters of the Crnojevića River and spring in its valley. The other is widespread throughout the sub-lacustrine We would like to thank

Holocene paleoenvironmental evolution of the Acıgöl paleo maar lake (Nevşehir, Central Anatolia)

et al. 2019

View full text Add to dashboard Cite

Acıgöl (Nevşehir, Central Anatolia) is a drained crater lake. Acıgöl maar was formed by the violent vapor explosions due to the interaction of hot rhyolitic magma with the (sub-)surface water during the latest Pleistocene. A 844 cm-deep borehole was drilled at the maar and 713 cm-thick Acıgöl Core Succession (ACS) was retrieved. The ACS is mainly composed of lower laminated and upper non-laminated mudstones (sandy, silty, and clayey) with rare organic and volcanic interlayers. Eleven ostracod taxa (Cypris pubera, Plesiocypridopsis newtoni, Heterocypris salina, Eucypris cf. heinrichi, Candona candida, Candona meerfeldiana, Pseudocandona marchica, Cyclocypris sp., Ilyocypris bradyi, Limnocythere inopinata, and Darwinula stevensoni) were determined in this study. Along with ostracods, gastropods (Gyraulus piscinarum and Stagnicola sp.), pelecypods (Pisidium personatum), charophytes, and fish remains were also observed, while diatoms are the most frequent and abundant assemblage of the ACS. The assemblage at the lower parts of ACS mainly indicates wetter, freshwater to oligohaline, and oligotrophic and relatively deep lacustrine conditions alternating with short lake shrinkage intervals. On the other hand, the fauna at the upper part of the ACS points out to saline, shallow, and warmer lacustrine conditions.

In a time of rapid environmental changes, identification of the effects of climate warming on charophytes (Characeae, Charophyta) will enable the optimization of conservation measures, especially for extremely rare species. Lychnothamnus barbatus is one of the rarest charophytes worldwide, which has decreased in the number of occupied sites over the last century. However, the recolonization of former sites has been observed in recent years (e.g. Lake Kuźnickie, Poland). The study aimed to analyse the effects of climatic changes and human pressure on the L. barbatus population. Three 30 cm sediment cores were collected from minimum, average, and maximum depths of L. barbatus occurrence to determine the past vegetation composition. Sediment cores were dated using the radioisotopes lead‐210, caesium‐137, and carbon‐14. A spatial analysis of the lake catchment changes during the last 120 years was also conducted. The study demonstrated L. barbatus presence in Lake Kuźnickie at the beginning of the 16th century. However, a sharp increase in the proportion of this species in the vegetation community occurred in the 19th century and during climate warming at the end of the Little Ice Age. Factors that significantly influenced the present occurrence of the L. barbatus population included improvement in water quality and the oospore bank deposited in the bottom sediments. This study is the first palaeoreconstruction in a modern lake dominated by L. barbatus. Based on the history of L. barbatus in Lake Kuźnickie after the end of the Little Ice Age, the positive effect of climate warming on the contemporary recovery of this charophyte is postulated. The reaction of L. barbatus to climate warming appears to differ from commonly accepted scenarios for aquatic macrophytes because its recovery in the past and at present coincided with increases in air temperature. This research indicated the appropriate management and conservation practices for lakes with L. barbatus populations.
