Arrival dates of male and female willow warblers (Phylloscopus trochilus) to their breeding site in Sweden 1979-2016Johanna 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 genusG 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 vertebratesWilliam 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 vulnerabilityYilin 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...
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...
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...
Subfamily Rubioideae is the largest of the main lineages in the coffee family (Rubiaceae), with over 8,000 species and 29 tribes. Phylogenetic relationships among tribes and other major clades within this group of plants are still only partly resolved despite considerable efforts. While previous studies have mainly utilized data from the organellar genomes and nuclear ribosomal DNA, we here use a large number of low-copy nuclear genes obtained via a target capture approach to infer...
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...
