The Bering Land Bridge (BLB) last connected Eurasia and North America during the Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations of a once wide-ranging group, the caballine horses (Equus spp.). Using a panel of 187 mitochondrial and...
The genus Coreomyces (Laboulbeniaceae, Laboulbeniomycetes, Ascomycota) includes minute parasites on water boatmen (Corixidae, Hemiptera, Insecta). This taxonomic study is primarily based on freshly sampled corixids infected by Coreomyces from Sweden, although a few samples from Denmark and Turkey were also included. All records were verified using DNA sequence data from the internal transcribed spacer region and large subunit of the nuclear ribosomal DNA repeat region. We recognise four species, two of which are new to...

Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...
This dataset contains data from a study described in the paper: Ericson, P.G.P., Irestedt, M., She, H., and Qu, Y. (2021) "Genomic signatures of rapid adaptive divergence in a tropical montane species". Biology Letters (in print). The study investigates allopatric divergence and selection in Archbold’s Bowerbird (Amblyornis papuensis), an iconic bird living in a tropical mountain region in New Guinea, using a novel chromosome-level genome and population genomic comparisons. Our results show that the two...
The two data files consist of sequence alignments in FASTA format. The file 'Distichium_alignment_ITS.txt' is the alignment used for the analysis resulting in the network in Fig. 1A in the paper and the file 'Distichium_alignment_3 markers.txt' is the alignment used for the analysis resulting in the network in Fig. 1B. The GenBank numbers corresponding with the sequence numbers can be found in Appendix 1 in the paper.
The dataset lists the diploid read lengths for nine microsatellites of 655 individuals of Coregonus fishes (Baltic and Siberian ciscoes, C. albula, C. fontanae, C. lucinensis, C. sardinella plus one C. maraena population) from 18 populations in Germany, Sweden, Finland, Poland and Russia. The nine microsatellites are BWF1, BWF2, Cisco126, Cisco157, Cisco90, Cocl23, Sfo23, Sfo8, Str73.
The file “Raw data.csv” contains all data used for the analyses of the article “The effects of four decades of climate change on the breeding ecology of an avian sentinel species across a 1500-km latitudinal gradient are stronger at high latitudes” (DOI: 10.1002/ece3.7459). This data was used to investigate the effect of climate warming on the breeding time and breeding success of European pied flycatchers breeding in Sweden during 1982-2017. The data set contains 29035...
Data from: The Sulawesi Thrush (Cataponera turdoides; Aves: Passeriformes) belongs to the genus TurdusAndrew Hart Reeve, Mozes P. K. Blom, Petter Zahl Marki, Romina Batista, Urban Olsson, Veronica Nyström Edmark, Martin Irestedt & Knud Andreas Jønsson
The Asian and Australo-Papuan faunas meet and intermix across the islands of Wallacea. Untangling the origins and relationships of the species inhabiting these archipelagos is an ongoing project that has lasted for well over a century. In recent years, molecular phylogenetic studies have made considerable progress in clarifying the affinities of enigmatic Wallacean taxa; but taxonomic riddles remain, even in groups as well studied as birds. Such is the case with Sulawesi Thrush Cataponera turdoides,...
Background: Allopatric speciation has played a particularly important role in archipelagic settings where populations evolve in isolation after colonizing different islands. The Indo-Australasian island realm is an unparalleled natural laboratory of biotic diversification. Here we explore how the level of earth-historic isolation has influenced genetic differentiation across the region by investigating phylogeographic patterns in the Pitta sordida species complex. Results: We generated a de novo genome and compared population genomics of 29 individuals of Pitta...
Reduced fitness through genetic drift and inbreeding is a major threat to small and isolated populations. Although previous studies have generally used genetically verified pedigrees to document effects of inbreeding and gene flow, these often fail to capture the whole inbreeding history of the species. By assembling a draft arctic fox (Vulpes lagopus) genome and re-sequencing complete genomes of 23 additional foxes born before and after a well-documented immigration event in Scandinavia, we here look...
Data from: Go large or go conical: allometric trajectory of an early Cambrian acrotretide brachiopodZhiliang Zhang, Timothy Topper, Yanlong Chen, Luke Stroze, Feiyang Chen, Lars Holmer, Glenn Brock & Zhifei Zhang
Acrotretides are extinct micromorphic brachiopods that exhibited considerable morphological variation during their rapid evolution in the early Palaeozoic. The plano-conical shells of acrotretides are distinct in comparison to other brachiopod groups and despite their diversity and abundance in early Palaeozoic communities, their origins, early evolution, life history and phylogeny are poorly understood. Here, we employ advanced geometric morphometrics to quantitatively investigate ontogenetic variation and allometry in the ventral valve of the oldest known acrotretide species...
Bryozoans (ectoprocts or moss animals) are aquatic, dominantly sessile, filter-feeding lophophorates that construct an organic or calcareous modular colonial (clonal) exoskeleton. The presence of six major orders of bryozoans with advanced polymorphisms in lower Ordovician rocks strongly suggests a Cambrian origin for the largest and most diverse lophophorate phylum. However, a lack of convincing bryozoan fossils from the Cambrian has hampered resolution of the true origins and character assembly of earliest members of the group....
