Adaptive radiation is the likely source of much of the ecological and morphological diversity of life. How adaptive radiations proceed and what determines their extent remains elusive in most cases. Here we report the in-depth examination of the spectacular adaptive radiation of cichlid fishes in African Lake Tanganyika. Based on whole-genome phylogenetic analyses, multivariate morphological measurements of three ecologically relevant trait complexes (body shape, upper oral jaw morphology, and lower pharyngeal jaw shape), scoring of...

In addition to 327 primary types (excluding the Phoridae), 32 are represented by syntypes and 295 species represented by secondary types. The holdings include the following important specialist collections: Phoridae (H. Schmitz, E. Beyer, E. Baumann), Tipuloidea (B. Mannheims, H....

Phylogenomic analysis and morphological data suggest left-right swimming behavior evolved prior to the origin of the pelagic Phylliroidae (Gastropoda: Nudibranchia)

Jessica Goodheart & Heike Wägele
Evolutionary transitions from benthic to pelagic habitats are major adaptive shifts. Investigations into such shifts are critical for understanding the complex interaction between co-opting existing traits for new functions and novel traits that originate during or post-transition. Gastropod mollusks are of particular interest in regard to benthic-pelagic evolutionary transitions, as shifts from benthic to pelagic habitats are uncommon. Phylliroe is one such pelagic lineage in Phylliroidae, a family of holoplanktonic nudibranchs with a highly aberrant...

Data from: An integrative phylogenomic approach to elucidate the evolutionary history and divergence times of Neuropterida (Insecta: Holometabola)

Alexandros Vasilikopoulos, Bernhard Misof, Karen Meusemann, Doria Lieberz, Tomáš Flouri, Rolf G. Beutel, Oliver Niehuis, Torsten Wappler, Jes Rust, Ralph S. Peters, Alexander Donath, Lars Podsiadlowski, Christoph Mayer, Daniela Bartel, Alexander Böhm, Shanlin Liu, Paschalia Kapli, Carola Greve, James E. Jepson, Xingyue Liu, Xin Zhou, Horst Aspöck & Ulrike Aspöck
Background The latest advancements in DNA sequencing technologies have facilitated the resolution of the phylogeny of insects, yet parts of the tree of Holometabola remain unresolved. The phylogeny of Neuropterida has been extensively studied, but no strong consensus exists concerning the phylogenetic relationships within the order Neuroptera, and the timeline of diversification of thelineages of Neuropterida. Here, we assembled a novel transcriptomic dataset to address previously unresolved issues in the phylogeny of Neuropterida and to...

Riparian forests can mitigate warming and ecological degradation of agricultural headwater streams

Jarno Turunen, Vasco Elbrecht, Dirk Steinke & Jukka Aroviita
1. Riparian forests are commonly advocated as a key management option to mitigate the effects of agriculture on headwater stream biodiversity and ecosystem functions. However, the benefits of riparian forests might be reduced by uninterrupted catchment-scale pollution. 2.We studied the effects of riparian land use on multiple ecological endpoints in headwater streams in an agricultural landscape. We studied stream habitat characteristics, water temperature and algal accrual, and macrophyte, benthic macroinvertebrate and fish communities in 11...

Variation in body size and sexual size dimorphism in the most widely-ranging lizard: testing the effects of reproductive mode and climate

Evgeny Roitberg
Reproductive mode, ancestry, and climate are hypothesized to determine body-size variation in reptiles but their effects have rarely been estimated simultaneously, especially at the intraspecific level. The common lizard (Zootoca vivipara) occupies almost the entire Northern Eurasia and includes viviparous and oviparous lineages, thus representing an excellent model for such studies. Using body length data for >10,000 individuals from 72 geographically distinct populations over the species’ range we analysed how sex-specific adult body size and...

Gene expression remodelling and immune response during adaptive divergence in an African cichlid fish

Jelena Rajkov, Athimed El Taher, Astrid Böhne, Walter Salzburger & Bernd Egger
Variation in gene expression contributes to ecological speciation by facilitating population persistence in novel environments. Likewise, immune response can be a relevant factor in speciation driven by adaptation to different environments. Previous studies examining gene expression differences between recently diverged ecotypes often relied on only one pair of populations, targeted the expression of only a subset of genes, or used wild caught-individuals. Here, we investigated the contribution of habitat-specific parasites and symbionts and the underlying...

Analysis of RNA-seq, DNA target enrichment, and Sanger nucleotide sequence data resolves deep splits in the phylogeny of cuckoo wasps (Hymenoptera: Chrysididae)

Thomas Pauli, Karen Meusemann, Sandra Kukowka, Manuela Sann, Alexander Donath, Christoph Mayer, Jan Philip Oeyen, Yolanda Ballesteros, Alexander Berg, Eric Van Den Berghe, Hermes Escalona, Adalgisa Guglielmino, Manfred Niehuis, Massimo Olmi, Lars Podsiadlowski, Carlo Polidori, Jeroen De Rond, Paolo Rosa, Thomas Schmitt, Franco Strumia, Mareike Wurdack, Shanlin Liu, Xin Zhou, Bernhard Misof, Ralph Peters … & Oliver Niehuis
The wasp family Chrysididae (cuckoo wasps, gold wasps) comprises exclusively parasitoid and kleptoparasitic species, many of which feature a stunning iridescent coloration and phenotypic adaptations to their parasitic life style. Previous attempts to infer phylogenetic relationships among the family’s major lineages (subfamilies, tribes, genera) based on Sanger sequence data were insufficient to statistically resolve the monophyly and the phylogenetic position of the subfamily Amiseginae and the phylogenetic relationships among the tribes Allocoeliini, Chrysidini, Elampini, and...

Drought sensitivity of Empetrum nigrum shrub growth at the species’ southern lowland distribution range margin

Stef Weijers, Nils Hein, Julia Merkelbach & Katharina Zech
The ongoing warming of the Earth’s atmosphere is projected to cause a northward shift of species’ distributions, as they track their climatic optimum. In the rapidly warming Arctic, this has already led to an increase of shrubs in tundra ecosystems. While this northern expansion of woody biomass has been studied relatively extensively over the last decade, little research has been devoted to shrub growth responses at the southern margins of Northern Hemisphere shrubs. Here, we...

Phylogenomic analysis sheds light on the evolutionary pathways towards acoustic communication in Orthoptera

Hojun Song, Olivier Béthoux, Seunggwan Shin, Alexander Donath, Harald Letsch, Shanlin Liu, Duane D. McKenna, Guanliang Meng, Bernhard Misof, Lars Podsiadlowski, Xin Zhou, Benjamin Wipfler & Sabrina Simon
Acoustic communication is enabled by the evolution of specialised hearing and sound producing organs. In this study, we performed a large-scale macroevolutionary study to understand how both hearing and sound production evolved and affected diversification in the insect order Orthoptera, which includes many familiar singing insects, such as crickets, katydids, and grasshoppers. Using phylogenomic data, we firmly establish phylogenetic relationships among the major lineages and divergence time estimates within Orthoptera, as well as the lineage-specific...

Data from: Four myriapod relatives – but who are sisters? No end to debates on relationships among the four major myriapod subgroups

Nikolaus U. Szucsich, Daniela Bartel, Alexander Blanke, Alexander Böhm, Alexander Donath, Makiko Fukui, Simon Grove, Shanlin Liu, Oliver Macek, Ryuichiro Machida, Bernhard Misof, Yasutaka Nakagaki, Lars Podsiadlowski, Kaoru Sekiya, Shigekazu Tomizuka, Björn M. Von Reumont, Robert M. Waterhouse, Manfred Walzl, Guanliang Meng, Xin Zhou, Günther Pass & Karen Meusemann
Background: Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to morphological evidence but is in conflict with most previously published phylogenetic trees based on diverse molecular data. Outgroup choice and long-branch attraction effects were stated as possible explanations for these incongruencies. In this study, we addressed these issues by extending the myriapod and outgroup taxon sampling...

The roles of wing color pattern and geography in the evolution of Neotropical Preponini butterflies

Elena Ortiz-Acevedo, Juan P. Gomez, Marianne Espeland, Emmanuel Toussaint & Keith R. Willmott
Diversification rates and evolutionary trajectories are known to be influenced by phenotypic traits and the geographic history of the landscapes that organisms inhabit. One of the most conspicuous traits in butterflies is their wing color pattern, which has been shown to be important in speciation. The evolution of many taxa in the Neotropics has also been influenced by major geological events. Using a dated, species-level molecular phylogenetic hypothesis for Preponini, a colorful Neotropical butterfly tribe,...

Identification of scavenger receptors and thrombospondin type 1 repeat proteins potentially relevant for plastid recognition in Sacoglossa

Jenny Melo Clavijo, Silja Frankenbach, Cátia Fidalgo, Joao Serôdio, Alexander Donath, Angelika Preisfeld & Gregor Christa
Functional kleptoplasty is a photosymbiotic relationship, in which photosynthetically active chloroplasts serve as an intracellular symbiont for a heterotrophic host. Among Metazoa, functional kleptoplasty is only found in marine sea slugs belonging to the Sacoglossa and recently described in rhabdocoel worms. Although functional kleptoplasty has been intensively studied in Sacoglossa, the fundamentals of the specific recognition of the chloroplasts and their subsequent incorporation are unknown. The key to ensure the initiation of any symbiosis is...
