Detailed evaluations of genomic variation between sister species often reveal distinct chromosomal regions of high relative differentiation (i.e., “islands of differentiation” in FST), but there is much debate regarding the causes of this pattern. We briefly review the prominent models of genomic islands of differentiation and compare patterns of genomic differentiation in three closely related pairs of New World warblers with the goal of evaluating support for the four models. Each pair (MacGillivray's/mourning warblers; Townsend's/black-throated...
Human-induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host-parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Two competing theories, the Enemy Release Hypothesis, where invading hosts escape their original parasites; and the Novel Weapon Hypothesis, where invading hosts bring new parasites that have detrimental effects on native hosts, have been described to predict...
Data from: Genome-wide signals of drift and local adaptation during rapid lineage divergence in a songbirdGuillermo Friis, Guillermo Fandos, Amanda J. Zellmer, John E. McCormack, Brant C. Faircloth & Borja Milá
The formation of independent evolutionary lineages involves neutral and selective factors, and understanding their relative roles in population divergence is a fundamental goal of speciation research. Correlations between allele frequencies and environmental variability can reveal the role of selection, yet the relative contribution of drift can be difficult to establish. Recently diversified taxa like the Oregon junco (Aves, Passerellidae, Junco hyemalis oreganus) of western North America provide ideal scenarios to apply genetic-environment association analyses (GEA)...
Data from: Structural controls on photosynthetic capacity through juvenile-to-adult transition and needle aging in Mediterranean pinesVivian Kuusk, Ülo Niinemets & Fernando Valladares
1. Needle photosynthetic potentials strongly vary among primary (juvenile) and secondary (adult) needles (heteroblasty) in Pinus species, but there is limited understanding of the underlying structural, diffusional and chemical controls. 2. We studied differences in needle photosynthetic characteristics among current-year juvenile and adult needles and among different-aged adult needles in Mediterranean pines Pinus halepensis Mill., P. pinea L. and P. nigra J. F. Arnold subsp. salzmannii (Dunal) Franco, hypothesizing that needle anatomical modifications upon juvenile-to-adult...
The resolution of family conflicts over parental care involves elaborate behavioral interactions where signals and information exchange play a central role. Usually the focus is on offspring begging and adult signals and their effect on parental provisioning. Yet, despite offspring of many animal species display structural ornaments during parental dependency, their role in intra-family conflicts remains practically unexplored. In the blue tit, Cyanistes caeruleus, we experimentally manipulated nestling plumage color and food availability in 60...
Data from: New species of Karydomys (Rodentia) from the Miocene of Chios Island (Greece) and phylogenetic relationships of this rare democricetodontine genusRaquel López Antoñanzas, Pablo Peláez-Campomanes, Jêrome Prieto & Fabien Knoll
Karydomys is a rare and little diversified democricetodontine, of which only six species are currently recognized. This group of rodents is first recorded in the early Miocene (MN3) in China and spread quickly thereafter to Kazakhstan and Greece (MN4). Karydomys reached south‐western and central Europe by early middle Miocene times (MN5), from where it became extinct shortly thereafter (MN6). A new species of Karydomys is here described from the Miocene Keramia Formation of Chios Island...
Data from: Tracking data and retrospective analyses of diet reveal the consequences of loss of marine subsidies for an obligate scavenger, the Andean condorSergio A. Lambertucci, Joan Navarro, Jose Antonio Sánchez-Zapata, Keith A. Hobson, Pablo A.E. Alarcón, Guillermo Wiemeyer, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donazar
Over the last century, marine mammals have been dramatically reduced in the world’s oceans. We examined evidence that this change caused dietary and foraging pattern shifts of the Andean condor (Vultur gryphus) in Patagonia. We hypothesized that, after the decrease in marine mammals and the increase in human use of coastlines, condor diet changed to a more terrestrial diet which, in turn, influenced their foraging patterns. We evaluated the diet by means of stable isotope...
The recent development of Bayesian phylogenetic inference using Markov chain Monte Carlo (MCMC) techniques has facilitated the exploration of parameter-rich evolutionary models. At the same time, stochastic models have become more realistic (and complex) and have been extended to new types of data, such as morphology. Based on this foundation, we developed a Bayesian MCMC approach to the analysis of combined data sets and explored its utility in inferring relationships among gall wasps based on...
