Data from: Strong population structure in a species manipulated by humans since the Neolithic: the European fallow deer (Dama dama dama)

Karis H. Baker, Howard W.I. Gray, Veronica Ramovs, Despoina Mertzanidou, C Akin Peksen, C. Can Bilgin, Naomi Sykes & A.R. Hoelzel
Species that have been translocated and otherwise manipulated by humans may show patterns of population structure that reflect those interactions. At the same time, natural processes shape populations, including behavioural characteristics like dispersal potential and breeding system. In Europe, a key factor is the geography and history of climate change through the Pleistocene. During glacial maxima throughout that period, species in Europe with temperate distributions were forced south, becoming distributed among the isolated peninsulas represented...

Data from: Effects of feral cats on the evolution of anti-predator behaviours in island reptiles: insights from an ancient introduction

Binbin Li, Anat Belasen, Panayiotis Pafilis, Peter Bednekoff & Johannes Foufopoulos
Exotic predators have been the driving force behind the extinction of many island endemic species. We examined impacts of feral cats (Felis catus) on the abundance and anti-predator behaviors of Aegean wall lizards (Podarcis erhardii) in the Cyclades (Greece), where cats were introduced thousands of years ago. We compared populations with high and low cat density on Naxos and populations on surrounding islets with no cats. Results show that cats have strong negative effects on...

Habitat ranges of central Aegean islands' Oniscidea

Spyros Sfenthourakis, Kostas Triantis, Konstantinos Proios & Francois Rigal
Aim: To investigate responses of ecological specialization on area and environmental heterogeneity using a new metric. Location: Aegean islands (Greece) as a case study. Taxon: Terrestrial isopods as a case study. Methods: The new metric, ‘ecorichness’, provides an estimate of an island’s species in the specialists-generalists spectrum. Species presences on each island are replaced with the numbers of habitats they exploit in the study system. Values are summed for each island and standardized by its...

Supplementary data for: Abducens nerve palsy with ipsilateral excessive eye tearing attributed to internal carotid artery sympathetic plexus schwannoma

Lina Palaiodimou, Stefanos Lachanis, Eleni Bakola, Panagiotis Zis, Evangelia Kararizou, Marianna Papadopoulou & Georgios Tsivgoulis
A 65-year-old man developed subacute horizontal diplopia due to left-abducens nerve (AN) palsy and excessive left-eye tearing. Brain-MRI revealed a hyperintense T2-lesion with an elongated course within the left-carotid canal, presenting homogenous contrast-enhancement (Figure-1). The imaging findings were characteristic for an internal-carotid-artery sympathetic plexus (ICSP) schwannoma compressing the left-AN. Subsequent irritation of the deep petrosal nerve originating directly from ICSP and continuing as the vidian nerve may have led to the lacrimal gland edema and...

Data from: Ecological explanations to island gigantism: dietary niche divergence, predation and size in an endemic lizard

Anna Runemark, Kostas Sagonas & Erik I. Svensson
Although rapid evolution of body size on islands has long been known, the ecological mechanisms behind this island phenomenon remain poorly understood. Diet is an important selective pressure for morphological divergence. Here we investigate if selection for novel diets has contributed to the multiple independent cases of island gigantism in the Skyros wall lizard (Podarcis gaigeae) and if diet, predation, or both factors best explain island gigantism. We combined data on body size, shape, bite...

Data from: Oral anticoagulation in patients with chronic kidney disease: a systematic review and meta-analysis

Konark Malhotra, Muhammad Fawad Ishfaq, Nitin Goyal, Aristeidis H. Katsanos, John Parissis, Anne W Alexandrov, Andrei V. Alexandrov & Georgios Tsivgoulis
Objective: Data regarding the efficacy and safety of warfarin and Non-Vitamin K Antagonist Oral Anticoagulant (NOAC) among patients with chronic kidney disease (CKD) remain scarce. Methods: Systematic review and meta-analysis of studies involving CKD patients treated on OACs was conducted to evaluate following outcomes: ischemic stroke, intracerebral hemorrhage (ICH), combined ischemic and hemorrhagic stroke (strokecombined), stroke or systemic embolism, mortality, and major bleeding events. CKD was defined based on creatinine clearance (CrCl) ranging from mild...

Data from: Unravelling the history of hepatitis B virus genotypes A and D infection using a full-genome phylogenetic and phylogeographic approach

Evangelia-Georgia Kostaki, Timokratis Karamitros, Garyfallia Stefanou, Ioannis Mamais, Konstantinos Angelis, Angelos Hatzakis, Anna Kramvis & Dimitrios Paraskevis
Hepatitis B virus (HBV) infection constitutes a global public health problem. In order to establish how HBV was disseminated across different geographic regions, we estimated the levels of regional clustering for genotypes D and A. We used 916 HBV-D and 493 HBV-A full-length sequences to reconstruct their global phylogeny. Phylogeographic analysis was conducted by reconstruction of ancestral states using the criterion of parsimony. The putative origin of genotype D was in North Africa/Middle East. HBV-D...

Data from: Intraspecific competition, not predation, drives lizard tail loss on islands

Yuval Itescu, Rachel Schwarz, Shai Meiri & Panayiotis Pafilis
Tail autotomy is mainly considered an antipredator mechanism. Theory suggests that predation pressure relaxes on islands, subsequently reducing autotomy rates. Intraspecific aggression, which may also cause tail loss, probably intensifies on islands due to the higher abundance. We studied whether tail autotomy is mostly affected by predation pressure or by intraspecific competition. We further studied whether predator abundance or predator richness is more important in this context. To test our predictions, we examined multiple populations...

Data from: Operating length and velocity of human M. vastus lateralis fascicles during vertical jumping

Maria Elissavet Nikolaidou, Robert Marzilger, Sebastian Bohm, Falk Mersmann & Adamantios Arampatzis
Humans achieve greater jump height during a counter-movement jump (CMJ) than in a squat jump (SJ). However, the crucial difference is the mean mechanical power output during the propulsion phase, which could be determined by intrinsic neuro-muscular mechanisms for power production. We measured M. vastus lateralis (VL) fascicle length changes and activation patterns and assessed the force–length, force–velocity and power–velocity potentials during the jumps. Compared with the SJ, the VL fascicles operated on a more...

Biomechanics of the human thumb and the evolution of dexterity

Fotios Alexandros Karakostis, Daniel Haeufle, Ioanna Anastopoulou, Konstantinos Moraitis, Gerhard Hotz, Vangelis Tourloukis & Katerina Harvati
Systematic tool production and use is one of humanity’s defining characteristics, possibly originating as early as >3 million years ago.​1–3​ Although heightened manual dexterity is considered to be intrinsically intertwined with tool use and manufacture, and critical for human evolution, its role in the emergence of early culture remains unclear. Most previous research on this question exclusively relied on direct morphological comparisons between early hominin and modern human skeletal elements, assuming that the degree of...

Pathogenic and low frequency variants in children with central precocious puberty

Vassos Neocleous, Pavlos Fanis, Meropi Toumba, Barbara Gorka, Ioanna Kousiappa, George Tanteles, Michalis Iasonides, Nicolas Nicolaides, Yiolanda Christou, Kyriaki Michailidou, Stella Nicolaou, Savvas Papacostas, Athanasios Christoforides, Andreas Kyriakou, Dimitrios Vlachakis, Nicos Skordis & Leonidas Phylactou
Background Central precocious puberty (CPP) due to premature activation of GnRH secretion results in early epiphyseal fusion and to a significant compromise in the achieved final adult height. CPP is usually idiopathic and is disproportionally observed in girls compared to boys. Currently, only few genetic determinants of children with CPP have been described and the role they exert on the development of the disorder. In this original study rare variants in MKRN3, DLK1, KISS1, KISS1R...

Metal sources in the actively forming seafloor massive sulfide deposit of the Kolumbo volcano: Insight from the basement rocks

S. Hector , C. G. C. Patten, S. P. Kilias , D. Papanikolaou & C. G. C. Kolb
The shallow submarine Kolumbo volcano , located in the 5 Ma-to-present Aegean volcanic arc in Greece, hosts an active hydrothermal system currently forming polymetallic seafloor massive sulfide (SMS) mineralization on the seafloor, with high As, Ag, Au, Hg, Sb and Tl contents. It is one of the few known SMS deposits associated with continental margin volcanism. The hydrothermal system of the Kolumbo volcano represents an active hybrid analogue style of epithermal and VMS mineralization. The...

Data from: Fine with heat, problems with water: microclimate alters water loss in a thermally adapted insular lizard

Anat Belasen, Kinsey Brock, Binbin Li, Dimitra Chremou, Efstratios Valakos, Panayiotis Pafilis, Barry Sinervo & Johannes Foufopoulos
Global change, including habitat isolation and climate change, has both short- and long-term impacts on wildlife populations. For example, genetic drift and inbreeding result in genetic impoverishment in small, isolated populations, while species undergo range shifts or adaptive phenotypic change in response to shifts in environmental temperatures. In this study, we utilize a model system in which Holocene landscape changes have occurred to examine long-term effects of population isolation. To examine how isolation may constrain...

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is one of the top leading causes of death and disability, and its management is focused on reducing risk factors, relieving symptoms, and preventing exacerbations. The study aim was to describe COPD prescribing patterns in Greece by using existing health administrative data for outpatients. Methods: This is a retrospective cross-sectional study based on prescriptions collected by the largest social insurance fund, during the first and last trimester of 2012....

Data from: Selection, drift and introgression shape MHC polymorphism in lizards

Konstantinos Sagonas, Anna Runemark, Aglaia Antoniou, Petros Lymberakis, Panayiotis Pafilis, Efstratios D. Valakos, Nikos Poulakakis & Bengt Hansson
The Major Histocompatibility Complex (MHC) has long served as a model for the evolution of adaptive genetic diversity in wild populations. Pathogen-mediated selection is thought to be a main driver of MHC diversity, but it remains elusive to what degree selection shapes MHC diversity in complex biogeographical scenarios where other evolutionary processes (e.g. genetic drift and introgression) may also be acting. Here, we focus on two closely related green lizard species, Lacerta trilineata and L....

Tail regeneration alters the digestive performance of lizards

Kostas Sagonas, Aris Deimezis-Tsikoutas, Aikaterini Reppa, Iro Domenikou, Mirto Papafoti, Konstantina Synevrioti, Ioanna Polydouri, Anneta Voutsela, Aristoula Bletsa, Niki Karambotsi, Panayiotis Pafilis & Efstratios Valakos
Tissue regeneration is a fundamental evolutionary adaptation, which is well known in lizards that can regenerate their entire tail. However, numerous parameters of this process remain poorly understood. Lizard tail serves many functions. Thus, tail autotomy comes with many disadvantages and the need for quick regeneration is imperative. To provide the required energy and materials for caudal tissue building, lizards are expected to undergo a number of physiological and biochemical adjustments. Previous research showed that...

GnRH deficient patients with congenital hypogonadotropic hypogonadism: Novel genetic findings in ANOS1, RNF216, WDR11, FGFR1, CHD7 and POLR3A genes

Vassos Neocleous, Pavlos Fanis, Meropi Toumba, George Tanteles, Melpo Schiza, Feride Cinarli, Nicolas Nicolaides, Anastasis Oulas, George Spyrou, Christos Mantzoros, Dimitrios Vlachakis, Nicos Skordis & Leonidas Phylactou
Background: Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disease caused by Gonadotropin-Releasing Hormone (GnRH) deficiency. So far a limited number of variants in several genes have been associated with the pathogenesis of the disease. In this original research and review manuscript the retrospective analysis of known variants in ANOS1 (KAL1), RNF216, WDR11, FGFR1, CHD7 and POLR3A genes is described, along with novel variants identified in patients with CHH by the present study. Methods: Seven...

Data from: Everything is not everywhere: marine compartments shape phytoplankton assemblages

Sofie Spatharis, Vasiliki Lamprinou, Alexandra Meziti, Konstantinos Kormas, Daniel Danielidis, Evangelia Smeti, Daniel Roelke, Rebecca Mancy & George Tsirtsis
The idea that “everything is everywhere, but the environment selects” has been seminal in microbial biogeography, and marine phytoplankton is one of the prototypical groups used to illustrate this. The typical argument has been that phytoplankton is ubiquitous, but that distinct assemblages form under environmental selection. It is well established that phytoplankton assemblages vary considerably between coastal ecosystems. However, the relative roles of compartmentalisation of regional seas and site-specific environmental conditions in shaping assemblage structures,...
