Evidence for asymmetrical divergence-gene flow of nuclear loci, but not mitochondrial loci, between seabird sister species: blue-footed (Sula nebouxii) and Peruvian (S. variegata) boobies.

open access: yesPLoS ONE, 2013
Understanding the process of speciation requires understanding how gene flow influences divergence. Recent analyses indicate that divergence can take place despite gene flow and that the sex chromosomes can exhibit different levels of gene flow than ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia

open access: yesEcography, EarlyView.
Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

Beyond Genes: Metabolomic Evidence Indicates Potential Species‐Level Differentiation in European Wild Rabbits

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The European rabbit (Oryctolagus cuniculus) plays a key ecological role in Mediterranean ecosystems, yet its populations are declining. Two subspecies, O. c. algirus and O. c. cuniculus, are present in the Iberian Peninsula and exhibit genetic, phenotypic, and ecological differences.

Coexistence in Sympatry With Gene Flow Before Speciation Has Completed

open access: yesMolecular Ecology
ABSTRACT Incipient species often coexist in sympatry before complete reproductive isolation has evolved between them. How do they persist in the face of hybridization and gene flow? The challenge is more acute than ordinary ecological coexistence not only because gene flow erodes and recombines genetic differences,

Prevalence of Colonization, Association With Disease Stage and Effect of Eradication of Staphylococcus aureus in Cutaneous T‐Cell Lymphoma: A Systematic Review and Meta‐Analysis

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Cutaneous T‐cell lymphoma (CTCL) is a rare and heterogeneous group of skin‐homing lymphomas with a largely unknown pathogenesis. Staphylococcus aureus (S. aureus) colonization has been implicated in exacerbating CTCL, particularly in advanced stages. Objectives This study assessed the prevalence of S.

Genomic regions of current low hybridisation mark long-term barriers to gene flow in scarce swallowtail butterflies.

open access: yesPLoS Genetics
Many closely related species continue to hybridise after millions of generations of divergence. However, the extent to which current patterning in hybrid zones connects back to the speciation process remains unclear: does evidence for current multilocus ...

Establishment and maintenance of sexual preferences that cause a reproductive isolation between medaka strains in close association

open access: yesBiology Open, 2017
Animals choose reproductive partners based on their sexual preferences which are established at a certain time point before, during, or after sexual maturation.

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.
