Data from: Deep-sea benthic ostracodes from multiple core and epibenthic sledge samples in Icelandic watersMoriaki Yasuhara, Maria Grimm, Simone N. Brandão, Anna Jöst, Hisayo Okahashi, Hokuto Iwatani, Alexandra Ostmann & Pedro Martínez Arbizu
Deep-sea benthic Ostracoda (Crustacea) in Icelandic waters are poorly known. Here we report deep-sea ostracode assemblages from the multiple core (MUC) and the epibenthic sledge (EBS) samples collected from Icelandic waters by the first cruise of the IceAGE (Icelandic Marine Animals: Genetics and Ecology) project. Samples from shelf-edge and lower-bathyal working areas are examined. The results show (1) distinct MUC and EBS faunas due to the large difference in mesh size of MUC and EBS;...
Data from: Environmental transmission of a personality trait: foster parent exploration behaviour predicts offspring exploration behaviour in zebra finchesWiebke Schuett, Sasha R. X. Dall, Alastair J. Wilson & Nick J. Royle
Consistent behavioural differences among individuals are common in many species and can have important effects on offspring fitness. To understand such ‘personality’ variation, it is important to determine the mode of inheritance, but this has been quantified for only a few species. Here, we report results from a breeding experiment in captive zebra finches, Taeniopygia guttata, in which we cross-fostered offspring to disentangle the importance of genetic and non-genetic transmission of behaviour. Genetic and foster-parents’...
Data from: Offspring dynamics affect food provisioning, growth and mortality in a brood-caring spiderJasmin Ruch, Marie E. Herberstein & Jutta M. Schneider
In brood-caring species, family members are faced with a conflict over resource distribution. While parents are selected to adapt the amount of care according to their offspring's needs, offspring might be selected to demand more care than optimal for parents. Recent studies on birds have shown that the social network structure of offspring affects the amount of care and thus the fitness of families. Such a network structure of repeated interactions is probably influenced by...
Data from: Decisive datasets in phylogenomics: lessons from studies on the phylogenetic relationships of primarily wingless insectsEmiliano Dell'Ampio, Karen Meusemann, Nikolaus U. Szucsich, Ralph S. Peters, Benjamin Meyer, Janus Borner, Malte Petersen, Andre J. Aberer, Alexandros Stamatakis, Manfred G. Walzl, Bui Quang Minh, Arndt Von Haeseler, Ingo Ebersberger, Günther Pass & Bernhard Misof
Phylogenetic relationships of the primarily wingless insects are still considered unresolved. Even the most comprehensive phylogenomic studies that addressed this question did not yield congruent results. In order to get a grip on these problems, we here analyzed the sources of incongruence in these phylogenomic studies using an extended transcriptome dataset.Our analyses showed that unevenly distributed missing data can be severely misleading by inflating node support despite the absence of phylogenetic signal. In consequence, only...
Data from: Albinism in phylogenetically and geographically distinct populations of Astyanax cavefish arises through the same loss-of-function Oca2 alleleJoshua B. Gross & Horst Wilkens
The Mexican tetra, Astyanax mexicanus, comprises 29 populations of cave-adapted fish distributed across a vast karst region in northeastern Mexico. These populations have a complex evolutionary history, having descended from "old" and "young" ancestral surface-dwelling stocks that invaded the region ~8 MYa and ~2.1 MYa, respectively. This study investigates a set of captive, pigmented Astyanax cavefish collected from the Micos cave locality in 1970, in which albinism appeared over the last two decades. We combined...
Comparative research on food web structure has revealed generalities in trophic organization, produced simple models, and allowed assessment of robustness to species loss. These studies have mostly focused on free-living species. Recent research has suggested that inclusion of parasites alters structure. We assess whether such changes in network structure result from unique roles and traits of parasites or from changes to diversity and complexity. We analyzed seven highly resolved food webs that include metazoan parasite...
Data from: Evidence for selective sweeps by Wolbachia infections: phylogeny of Altica leaf beetles and their reproductive parasitesRegina Jäckel, Diana Mora & Susanne Dobler
Infections with maternally inherited Wolbachia bacteria may have dramatic influences on reproductive traits and speciation patterns of their hosts. We here show that in the beetle genus Altica, infection has influenced phylogenetic patterns of the host’s mtDNA and different strains led to repeated selective sweeps. By comparing a COI/II based phylogeny of the hosts with a phylogeny of the bacteria based on ftsZ, we show that co-speciation is rare and restricted to few recently diverged...
