Data from: Testing the potential of DNA barcoding in vertebrate radiations: the case of the littoral cichlids (Pisces, Perciformes, Cichlidae) from Lake Tanganyika

Floris C. Breman, Sara Loix, Kurt Jordaens, Jos Snoeks & Maarten Van Steenberge
We obtained 398 cytochrome c oxidase subunit I barcodes of 96 morphospecies of Lake Tanganyika (LT) cichlids from the littoral zone. The potential of DNA barcoding in these fishes was tested using both species identification and species delineation methods. The best match (BM) and best close match (BCM) methods were used to evaluate the overall identification success. For this, three libraries were analysed in which the specimens were categorized into Operational Taxonomic Units (OTU) in...

Data from: Allometry in Anisian (Middle Triassic) segminiplanate conodonts and its implications for conodont taxonomy

Yanlong Chen, Thomas A. Neubauer, Leopold Krystyn & Sylvain Richoz
Conodonts are a clade of chordates and are valuable indicator fossils for biostratigraphy. The segminiplanate (neogondolelliform) conodonts represent a major morphological group ranging from upper Carboniferous to Upper Triassic marine sediments. However, the morphological similarity of segminiplanate P1 elements generates problems for taxonomy, especially in the Permian and Triassic clades. This paper represents the first study of morphological variation in Triassic segminiplanate conodonts using a geometric morphometric approach. The laminar microstructures observed in conodont cross-sections...

Data from: Escape from the cryptic species trap: lichen evolution on both sides of a cyanobacterial acquisition event

Kevin Schneider, Philipp Resl & Toby Spribille
Large, architecturally complex lichen symbioses arose only a few times in evolution, increasing thallus size by orders of magnitude over those from which they evolved. The innovations that enabled symbiotic assemblages to acquire and maintain large sizes are unknown. We mapped morphometric data against an eight-locus fungal phylogeny across one of the best-sampled thallus size transition events, the origins of the Placopsis lichen symbiosis, and used a phylogenetic comparative framework to explore the role of...

Data from: Adult sex ratio and operational sex ratio exhibit different temporal dynamics in the wild

María Cristina Carmona-Isunza, Sergio Ancona, Tamás Székely, Alfonso P. Ramallo-González, Medardo Cruz-López, Martín Alejandro Serrano-Meneses & Clemens Küpper
Adult sex ratio (ASR, the proportion of adult males in the adult population) and operational sex ratio (OSR, the proportion of sexually active males in the mating pool) are fundamental properties of breeding populations and they are often linked to mating systems and sexual selection. However, ASR and OSR emerge via different routes in a population and may exhibit different temporal patterns. Here, we use data from a well-monitored polygamous snowy plover Charadrius nivosus population...
