Differences in decompression of the high-pressure Cycladic Blueschist Unit (Naxos Island, Greece): what can inclusions tell us?

Determining the tectonic evolution and thermal structure of a tectonic unit that experiences a subduction-related pressure temperature (P-T) loop is challenging. Within a single unit, P-T conditions can vary from top to bottom which can be only revealed by detailed petrological work. We present micropetrological data of the middle section of the Cycladic Blueschist Unit (CBU) in Naxos, Greece, which indicate a different P-T loop than the top of the section. In the middle section,...

Arrival dates of male and female willow warblers (Phylloscopus trochilus) to their breeding site in Sweden 1979-2016

Johanna Hedlund, Thord Fransson, Cecilia Kullberg, Jan-Olov Persson & Sven Jakobsson
Protandry is a widespread life-history phenomenon describing how males precede females at the site or state of reproduction. In migratory birds, protandry has important influence on individual fitness, the migratory syndrome and phenological response to climate change. Despite its significance, accurate analyses on the dynamics of protandry using data sets collected at the breeding site, are lacking. Basing our study on records collected daily, spanning a period of 38 years, we aim to investigate protandry...

UCE Phylogenomics resolves major relationships among Ectaheteromorph ants (Hymenoptera: Formicidae: Ectatomminae, Heteroponerinae): A new classification for the subfamilies and the description of a new genus

G P Camacho, W Franco, M G Branstetter, M R Pie, J T Longino, T R Schultz & R M Feitosa
Uncovering the evolutionary history of the subfamilies Ectatomminae and Heteroponerinae, or ectaheteromorphs, is key to understanding a major branch of the ant tree of life. Despite their diversity and ecological importance, phylogenetic relationships in the group have not been well explored. One particularly suitable tool for resolving phylogeny is the use of ultraconserved elements (UCEs), which have been shown to be ideal markers at a variety of evolutionary time scales. In the present study, we...

Increasing morphological disparity and decreasing optimality for jaw speed and strength during the radiation of jawed vertebrates

William Deakin, Philip Anderson, Wendy Den Boer, Thomas Smith, Jennifer Hill, Martin Rücklin, Philip Donoghue & Emily Rayfield
The Siluro-Devonian adaptive radiation of jawed vertebrates, which underpins almost all living vertebrate biodiversity, is characterised by the evolutionary innovation of the lower jaw. Multiple lines of evidence have suggested that the jaw evolved from a rostral gill arch, but when the jaw took on a feeding function remains unclear. We quantified the variety of form in the earliest jaws in the fossil record and , from which we generated a range of theoretical morphospacelogies...

VCF datasets and analysis scripts for: The combination of genomic offset and niche modelling provides insights into climate change-driven vulnerability

Yilin Chen, Zhiyong Jiang, Ping Fan, Per Ericson, Gang Song, Xu Luo, Fumin Lei & Yanhua Qu
Global warming is increasingly exacerbating biodiversity loss. Populations locally adapted to spatially heterogeneous environments may respond differentially to climate change, but this intraspecific variation has only recently been considered when modelling vulnerability under climate change. Here, we incorporate intraspecific variation in genomic offset and ecological niche modelling to estimate climate change-driven vulnerability in two bird species in the Sino-Himalayan Mountains. We found that the cold-tolerant populations show higher genomic offset but risk less challenge for...

Biologic agents mediating matter-flow inside the porous igneous oceanic crust, Vesteris Seamount, Greenland Sea

Hinrich Schmid-Beurmann, Magnus Ivarsson, Wolfgang Bach, Wolf-Achim Kahl & Jörn Peckmann
Microorganisms within the lithosphere are biologic agents settling in niches inside the terrestrial and oceanic crust, populating the extreme environments of the deep biosphere. The fossil record of the permeable igneous oceanic crust, constructed out of primitive extrusive rock, opens a window into Earth’s early evolution and serves as an analogue for life in extraterrestrial worlds. In 2019, samples of highly porous basanites of Vesteris Seamount in the Greenland Sea were retrieved during a cruise...

Skyline fossilized birth-death priors resolve deep root attraction in total-evidence dating

Chi Zhang, Fredrik Ronquist & Tanja Stadler
Several total-evidence dating studies under the fossilized birth-death (FBD) prior produced very old age estimates which are not supported by the fossil record, and this phenomenon has been termed "deep root attraction'' (DRA). For the Hymenoptera and Eutheria data, utilizing diversified extant sampling in the FBD process has been shown to greatly reduce the DRA effect. However, it is unclear how to proceed in data analyses where typically both the random and diversified samplings are...

Supporting data: Speciation and population divergence in a mutualistic seed dispersing bird

Maria Nilsson Janke, Jordi De Raad, Martin Päckert, Martin Irestedt, Axel Janke, Alexey Kryukov, Jochen Martens, Yaroslav Red’kin, Yuehua Sun, Til Töpfer, Matthias Schleuning & Eike-Lena Neuschulz
Bird-mediated seed dispersal is crucial for the regeneration and viability of ecosystems, often resulting in complex mutualistic species networks. Yet, how this mutualism drives the evolution of seed dispersing birds is still poorly understood. In the present study we combine whole genome re-sequencing analyses and morphometric data to assess the evolutionary processes that shaped the diversification of the Eurasian nutcracker (Nucifraga), a seed disperser known for its mutualism with pines (Pinus). Our results show that...

Genomic and morphometric data used in a demographic study of Coragyps vultures

Per Ericson & Yanhua Qu
The New World Vulture [Coragyps] occidentalis (L. Miller, 1909) is one of many species that were extinct by the end of the Pleistocene. To understand its evolutionary history we sequenced the genome of a 14,000-year-old [Coragyps] occidentalis found associated with megaherbivores in the Peruvian Andes. occidentalis has been viewed as the ancestor, or possibly sister, to the extant Black Vulture Coragyps atratus, but genomic data shows occidentalis to be deeply nested within the South American...
