Data from: Variation in the post-mating fitness landscape in fruitflies

Claudia Fricke & Tracey Chapman
Sperm competition is pervasive and fundamental to determining a male’s overall fitness. Sperm traits and seminal fluid proteins (Sfps) are key factors. However, studies of sperm competition may often exclude females that fail to remate during a defined period. Hence, the resulting datasets contain fewer data from the potentially fittest males that have most success in preventing female remating. It is also important to consider a male’s reproductive success before entering sperm competition, which is...

Data from: Adaptive shaping of the behavioural and neuroendocrine phenotype during adolescence

Tobias D. Zimmermann, Sylvia Kaiser, Michael B. Hennessy & Norbert Sachser
Environmental conditions during early life can adaptively shape the phenotype for the prevailing environment. Recently, it has been suggested that adolescence represents an additional temporal window for adaptive developmental plasticity, though supporting evidence is scarce. Previous work has shown that male guinea pigs living in large mixed-sex colonies develop a low-aggressive phenotype as part of a queuing strategy that is adaptive for integrating into large unfamiliar colonies. By contrast, males living in pairs during adolescence...

Data from: An integrated model of phenotypic trait changes and site-specific sequence evolution

Eli Levy Karin, Susann Wicke, Tal Pupko & Itay Mayrose
Recent years have seen a constant rise in the availability of trait data, including morphological features, ecological preferences, and life history characteristics. These phenotypic data provide means to associate genomic regions with phenotypic attributes, thus allowing the identification of phenotypic traits associated with the rate of genome and sequence evolution. However, inference methodologies that analyze sequence and phenotypic data in a unified statistical framework are still scarce. Here, we present TraitRateProp, a probabilistic method that...

Data from: The fossil Osmundales (Royal Ferns)—a phylogenetic network analysis, revised taxonomy, and evolutionary classification of anatomically preserved trunks and rhizomes

Guido W. Grimm, Benjamin Bomfleur & Stephen McLoughlin
The Osmundales (Royal Fern order) originated in the late Paleozoic and is the most ancient surviving lineage of leptosporangiate ferns. In contrast to its low diversity today (less than 20 species in six genera), it has the richest fossil record of any extant group of ferns. The structurally preserved trunks and rhizomes alone are referable to more than 100 fossil species that are classified in up to 20 genera, four subfamilies, and two families. This...

Data from: Haemoglobin-mediated response to hyper-thermal stress in the keystone species Daphnia magna

Maria Cuenca Cambronero, Bettina Zeis & Luisa Orsini
Anthropogenic global warming has become a major geological and environmental force driving drastic changes in natural ecosystems. Due to the high thermal conductivity of water and the effects of temperature on metabolic processes, freshwater ecosystems are among the most impacted by these changes. The ability to tolerate changes in temperature may determine species long-term survival and fitness. Therefore, it is critical to identify coping mechanisms to thermal and hyper-thermal stress in aquatic organisms. A central...

Data from: Precopulatory but not postcopulatory male reproductive traits diverge in response to mating system manipulation in Drosophila melanogaster

Kristina U. Wensing, Mareike Koppik & Claudia Fricke
Competition between males creates potential for pre- and postcopulatory sexual selection and conflict. Theory predicts that males facing risk of sperm competition should evolve traits to secure their reproductive success. If those traits are costly to females, the evolution of such traits may also increase conflict between the sexes. Conversely, under the absence of sperm competition, one expectation is for selection on male competitive traits to relax thereby also relaxing sexual conflict. Experimental evolution studies...

Data from: Hemimetabolous genomes reveal molecular basis of termite eusociality

Childers, Huyen Dinh, Harshavardhan Doddapaneni, Shannon Dugan, Johannes Gowin, Carolin Greiner, Yi Han, Haofu Hu, Daniel S.T. Hughes, Ann-Kathrin Huylmans, Carsten Kemena, Lukas P.M. Kremer, Sandra L. Lee, Alberto Lopez-Ezquerra, Ludovic Mallet, Jose M. Monroy-Kuhn, Annabell Moser, Shwetha C. Murali, Donna M. Muzny … & Erich Bornberg-Bauer
Around 150 million years ago, eusocial termites evolved from within the cockroaches, 50 million years before eusocial Hymenoptera, such as bees and ants, appeared. Here, we report the 2-Gb genome of the German cockroach, Blattella germanica, and the 1.3-Gb genome of the drywood termite Cryptotermes secundus. We show evolutionary signatures of termite eusociality by comparing the genomes and transcriptomes of three termites and the cockroach against the background of 16 other eusocial and non-eusocial insects....

Data from: Speciation network in Laurasiatheria: retrophylogenomic signals

Liliya Doronina, Gennady Churakov, Andrej Kuritzin, Jingjing Shi, Robert Baertsch, Hiram Clawson & Juergen Schmitz
Rapid species radiation due to adaptive changes or occupation of new ecospaces challenges our understanding of ancestral speciation and the relationships of modern species. At the molecular level, rapid radiation with successive speciations over short time periods—too short to fix polymorphic alleles—is described as incomplete lineage sorting. Incomplete lineage sorting leads to random fixation of genetic markers and hence, random signals of relationships in phylogenetic reconstructions. The situation is further complicated when you consider that...

Data from: Does functional soil microbial diversity contribute to explain within-site plant β-diversity in an alpine grassland and a dehesa meadow in Spain?

Yoseph N. Araya, Maik Bartelheimer, Cipriano J. Valle, Rosa M. Crujeiras & Gonzalo García-Baquero
Questions Once effects of hydrological and chemical soil properties have been accounted for, does soil microbial diversity contribute to explain change in plant community structure (i.e. within-site β-diversity)? If so, at what spatial scale does microbial diversity operate? Location La Mina in Moscosa Farm, Salamanca, western Spain (dehesa community) and Laguna Larga in the Urbión Peaks, Soria, central-northern Spain (alpine grassland). Methods The abundance of vascular plant species, soil Gram-negative microbial functional types and soil...

Data from: Specificity of oral immune priming in the red flour beetle Tribolium castaneum

Momir Futo, Marie P. Sell, Megan A.M. Kutzer, Joachim Kurtz & Megan A. M. Kutzer
Immune specificity is the degree to which a host’s immune system discriminates among various pathogens or antigenic variants. Vertebrate immune memory is highly specific due to antibody responses. On the other hand, some invertebrates show immune priming, i.e. improved survival after secondary exposure to a previously encountered pathogen. Until now, specificity of priming has only been demonstrated via the septic infection route or when live pathogens were used for priming. Therefore, we tested for specificity...

Data from: Sexual conflict over remating interval is modulated by the sex peptide pathway

Damian T. Smith, Naomi V. E. Clarke, James M. Boone, Claudia Fricke & Tracey Chapman
Sexual conflict, in which the evolutionary interests of males and females diverge, shapes the evolution of reproductive systems across diverse taxa. Here, we used the fruit fly to study sexual conflict in natural, three-way interactions comprising a female, her current and previous mates. We manipulated the potential for sexual conflict by using sex peptide receptor (SPR) null females and by varying remating from 3 to 48 h, a period during which natural rematings frequently occur....

Data from: Gene expression changes in male accessory glands during ageing are accompanied by reproductive decline in Drosophila melanogaster

Mareike Koppik & Claudia Fricke
Senescence is accompanied by loss of reproductive functions. Here we studied reproductive ageing in Drosophila melanogaster males and asked whether the expected decline in male reproductive success is due to diminished functionality of the male accessory gland. The male accessory gland produces the majority of seminal fluid proteins (SFPs) transferred to the female at mating. SFPs induce female post-mating changes and are key to male reproductive success. We measured age-dependent gene expression changes for five...
