Ecological Correlates of Ghost Lineages in Ruminants
Paleobiology, 38(1), 2012, pp. 101–111 Ecological correlates of ghost lineages in ruminants Juan L. Cantalapiedra, Manuel Herna´ndez Ferna´ndez, Gema M. Alcalde, Beatriz Azanza, Daniel DeMiguel, and Jorge Morales Abstract.—Integration between phylogenetic systematics and paleontological data has proved to be an effective method for identifying periods that lack fossil evidence in the evolutionary history of clades. In this study we aim to analyze whether there is any correlation between various ecomorphological variables and the duration of these underrepresented portions of lineages, which we call ghost lineages for simplicity, in ruminants. Analyses within phylogenetic (Generalized Estimating Equations) and non-phylogenetic (ANOVAs and Pearson correlations) frameworks were performed on the whole phylogeny of this suborder of Cetartiodactyla (Mammalia). This is the first time ghost lineages are focused in this way. To test the robustness of our data, we compared the magnitude of ghost lineages among different continents and among phylogenies pruned at different ages (4, 8, 12, 16, and 20 Ma). Differences in mean ghost lineage were not significantly related to either geographic or temporal factors. Our results indicate that the proportion of the known fossil record in ruminants appears to be influenced by the preservation potential of the bone remains in different environments. Furthermore, large geographical ranges of species increase the likelihood of preservation. Juan L. Cantalapiedra, Gema Alcalde, and Jorge Morales.

Female Genetic Distribution Bias in Mitochondrial Genome Observed In
www.nature.com/scientificreports OPEN Female genetic distribution bias in mitochondrial genome observed in Parkinson’s Disease patients in Received: 07 April 2015 Accepted: 26 October 2015 northern China Published: 25 November 2015 Qiaohong Chu1, Xiaoguang Luo2, Xiaoni Zhan1, Yan Ren2 & Hao Pang1 Genetic polymorphisms associated with susceptibility to Parkinson’s disease (PD) have been described in mitochondrial DNA (mtDNA). To explore the potential contribution of mtDNA mutations to the risk of PD in a Chinese population, we examined the linkage relationship between several single nucleotide polymorphisms (SNPs) and haplotypes in mtDNA and PD. We genotyped 5 SNPs located on coding genes using PCR-RFLP analysis. A specific allele 10398G demonstrated an increased risk of PD (OR 1.30; 95% CI 0.95–1.76; P = 0.013). After stratification by gender, the increased risk appeared to be more significant in females (OR 1.91; 95% CI 1.16–3.16; P = 0.001). But the significance only appeared in females under Bonferroni correction. No significant differences were detected for other SNPs (T4336C, G5460A, G9055A, and G13708A). Individual haplotype composed of 4336T-5460G-9055G-10398A-13708G was found to be associated with protective effect regarding PD (P = 0.0025). The haplotypes 4336T-5460G-9055G-10398G-13708G and 4336T-5460G-9055G- 10398A-13708G were more significantly associated in females (P = 0.0036 for risk and P = 0.0006 for protective effects). These data suggest that the A10398G and two haplotypes coupled with 10398A or 10398G are closely associated with susceptibility to PD in a northern Chinese population. This association demonstrated a female genetic distribution bias. -
Living in Two Places : Permanent Transiency In
living in two places: permanent transiency in the magadan region Elena Khlinovskaya Rockhill Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge CB2 1ER, UK; [email protected] abstract Some individuals in the Kolyma region of Northeast Russia describe their way of life as “permanently temporary.” This mode of living involves constant movements and the work of imagination while liv- ing between two places, the “island” of Kolyma and the materik, or mainland. In the Soviet era people maintained connections to the materik through visits, correspondence and telephone conversations. Today, living in the Kolyma means living in some distant future, constantly keeping the materik in mind, without fully inhabiting the Kolyma. People’s lives embody various mythologies that have been at work throughout Soviet Kolyma history. Some of these models are being transformed, while oth- ers persist. Underlying the opportunities afforded by high mobility, both government practices and individual plans reveal an ideal of permanency and rootedness.

A Longitudinal Genetic Survey Identifies Temporal Shifts in the Population
Heredity (2016) 117, 259–267 & 2016 Macmillan Publishers Limited, part of Springer Nature. All rights reserved 0018-067X/16 www.nature.com/hdy ORIGINAL ARTICLE A longitudinal genetic survey identifies temporal shifts in the population structure of Dutch house sparrows L Cousseau1, M Husemann2, R Foppen3,4, C Vangestel1,5 and L Lens1 Dutch house sparrow (Passer domesticus) densities dropped by nearly 50% since the early 1980s, and similar collapses in population sizes have been reported across Europe. Whether, and to what extent, such relatively recent demographic changes are accompanied by concomitant shifts in the genetic population structure of this species needs further investigation. Therefore, we here explore temporal shifts in genetic diversity, genetic structure and effective sizes of seven Dutch house sparrow populations. To allow the most powerful statistical inference, historical populations were resampled at identical locations and each individual bird was genotyped using nine polymorphic microsatellites. Although the demographic history was not reflected by a reduction in genetic diversity, levels of genetic differentiation increased over time, and the original, panmictic population (inferred from the museum samples) diverged into two distinct genetic clusters. Reductions in census size were supported by a substantial reduction in effective population size, although to a smaller extent. As most studies of contemporary house sparrow populations have been unable to identify genetic signatures of recent population declines, results of this study underpin the importance of longitudinal genetic surveys to unravel cryptic genetic patterns.

Stafford Jr. 15 & Michael Bunce 1 1234567890():,; Large-scale changes in global climate at the end of the Pleistocene significantly impacted ecosystems across North America. However, the pace and scale of biotic turnover in response to both the Younger Dryas cold period and subsequent Holocene rapid warming have been challenging to assess because of the scarcity of well dated fossil and pollen records that covers this period. Here we present an ancient DNA record from Hall’s Cave, Texas, that documents 100 vertebrate and 45 plant taxa from bulk fossils and sediment. We show that local plant and animal diversity dropped markedly during Younger Dryas cooling, but while plant diversity recovered in the early Holocene, animal diversity did not. Instead, five extant and nine extinct large bodied animals disappeared from the region at the end of the Pleistocene. Our findings suggest that climate change affected the local ecosystem in Texas over the Pleistocene-Holocene boundary, but climate change on its own may not explain the disappearance of the megafauna at the end of the Pleistocene. 1 Trace and Environmental DNA (TrEnD) Laboratory, School of Molecular and Life Sciences, Curtin University, Bentley, WA 6102, Australia. -
Sedimentary Biomarkers Reaffirm Human Impacts on Northern Beringian Ecosystems During the Last Glacial Period

ABBOTT, MATTHEW S. FINKENBINDER AND JONATHAN A. O’DONNELL Vachula, R. S., Huang, Y. , Russell, J. M., Abbott, M. B., Finkenbinder, M. S. & O’Donnell, J. A.: Sedimentary biomarkers reaffirm human impacts on northern Beringian ecosystems during the Last Glacial period. Boreas. https://doi.org/10.1111/bor.12449. ISSN 0300-9483. Our understanding of the timing of human arrival to the Americas remains fragmented, despite decades of active research and debate. Genetic research has recently led to the ‘Beringian standstill hypothesis’ (BSH), which suggests an isolated group of humans lived somewhere in Beringia for millennia during the Last Glacial, before a subgroup migrated southward into the American continents about 14 ka. Recently published organic geochemical data suggest human presence around Lake E5 on the Alaskan North Slope during the Last Glacial; however, these biomarker proxies, namely faecal sterols and polycyclic aromatic hydrocarbons (PAHs), are relatively novel and require replication to bolster their support of the BSH. Wepresent newanalyses of thesebiomarkers in the sediment archive of Burial Lake (latitude 68°260N, longitude 159°100W m a.s.l.) in northwestern Alaska. Our analyses corroborate that humans were present in Beringia during the Last Glacial and that they likely promoted fire activity. Our data also suggest that humans coexistedwith Ice Age megafauna for millenniaprior to theireventual extinction at the end of the Last Glacial. Lastly, we identify fire as an overlooked ecological component of the mammoth steppe ecosystem.
