Data from: Deep-sea benthic ostracodes from multiple core and epibenthic sledge samples in Icelandic waters

Moriaki 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: Idiosyncratic species effects confound size-based predictions of responses to climate change

Marion Twomey, Eva Brodte, Ute Jacob, Ulrich Brose, Tasman P. Crowe & Mark C. Emmerson
Understanding and predicting the consequences of warming for complex ecosystems and indeed individual species remains a major ecological challenge. Here, we investigated the effect of increased seawater temperatures on the metabolic and consumption rates of five distinct marine species. The experimental species reflected different trophic positions within a typical benthic East Atlantic food web, and included a herbivorous gastropod, a scavenging decapod, a predatory echinoderm, a decapod and a benthic-feeding fish. We examined the metabolism–body...

Data from: Effects of warming rate, acclimation temperature and ontogeny on the critical thermal maximum of temperate marine fish larvae

Marta Moyano, Caroline Candebat, Yannick Ruhbaum, Santiago Álvarez-Fernández, Guy Claireaux, José-Luis Zambonino-Infante & Myron A. Peck
Most of the thermal tolerance studies on fish have been performed on juveniles and adults, whereas limited information is available for larvae, a stage which may have a particularly narrow range in tolerable temperatures. Moreover, previous studies on thermal limits for marine and freshwater fish larvae (53 studies reviewed here) applied a wide range of methodologies (e.g. the static or dynamic method, different exposure times), making it challenging to compare across taxa. We measured the...

Data from: Producers and scroungers: feeding type composition changes with group size in a socially foraging spider

Marlis Dumke, Mariella E. Herberstein, Jutta M. Schneider & Marie E. Herberstein
In groups of socially foraging animals, feeding behaviour may change with group size in response to varying cost-benefit trade-offs. Numerous studies have described group size effects on group-average feeding behaviour, particularly emphasizing an increase in scrounging incidence for larger groups, where individuals (scroungers) feed from the food sources others (producers) discovered. However, individual variation in feeding behaviour remains unconsidered in the vast majority of these studies even though theoretical models presume individuals to specialize in...

Data from: Predator encounters have spatially extensive impacts on parental behaviour in a breeding bird community

Kadri Moks, Vallo Tilgar, Robert L. Thomson, Sara Calhim, Pauliina E. Järvistö, Wiebke Schuett, William Velmala & Toni Laaksonen
Predation risk has negative indirect effects on prey fitness, partly mediated through changes in behaviour. Evidence that individuals gather social information from other members of the population suggests that events in a community may impact the behaviour of distant individuals. However, spatially wide-ranging impacts on individual behaviour caused by a predator encounter elsewhere in a community have not been documented before. We investigated the effect of a predator encounter (hawk model presented at a focal...

Biased predation could promote convergence yet maintain diversity within Müllerian mimicry rings of Oreina leaf beetles

David Kikuchi, Samuel Waldron, Janne Valkonen, Susanne Dobler & Johanna Mappes
Müllerian mimicry is a classic example of adaptation, yet Müller’s original theory does not account for the persistence of diversity in mimicry rings, which has been a thorn in the side of one of the oldest models in evolutionary biology. Here, we aimed to assess how well classical Müllerian mimicry can account for the color polymorphism found in chemically defended Oreina leaf beetles, specifically testing its predictions for predator behavior. We also evaluated whether thermoregulation...

Phylogenomic resolution of sea spider diversification through integration of multiple data classes

Jesus Ballesteros, Emily Setton, Carlos Santibáñez-López, Claudia Arango, Georg Brenneis, Saskia Brix, Kevin Corbett, Esperanza Cano-Sánchez, Merai Dandouch, Geoffrey Dilly, Marc Eleaume, Guilherme Gainett, Cyril Gallut, Sean McAtee, Lauren McIntyre, Randy Moran, Pablo López-González, Gerhard Scholtz, Clay Williamson, Arthur Woods, Jakob Zehms, Ward Wheeler & Prashant Sharma
Despite significant advances in invertebrate phylogenomics over the past decade, the higher-level phylogeny of Pycnogonida (sea spiders) remains elusive. Due to the inaccessibility of some small-bodied lineages, few phylogenetic studies have sampled all sea spider families. Previous efforts based on a handful of genes have yielded unstable tree topologies. Here, we inferred the relationships of 89 sea spider species using targeted capture of the mitochondrial genome, 56 conserved exons, 101 ultraconserved elements, and three nuclear...

LT-Brazil: A database of leaf traits across biomes and vegetation types in Brazil

Eduardo Mariano, Taciana Gomes, Silvia Lins, Adibe Abdalla-Filho, Amin Soltangheisi, Maria Araújo, Rodrigo Almeida, Fernanda Augusto, Luiza Canisares, Siglea Chaves, Cristiane Costa, Thaís Diniz-Reis, Leonardo Galera, Melissa Martinez, Maristela Morais, Elen Perez, Lucas Reis, Carla Simon, Silvia Mardegan, Tomas Domingues, Raquel Miatto, Rafael Oliveira, Carla Reis, Gabriela Nardoto, Jens Kattge … & Luiz Martinelli
Motivation: Leaf traits represent an important component of plant functional strategies, and those related to carbon fixation and nutrient acquisition form the leaf economics spectrum. However, observations of functional leaf traits are underrepresented in tropical regions in comparison with those in temperate areas. Brazil, a country with continental scale and vast biodiversity is a timely example, where many biomes are impacted by human activities and climate change. However, leaf traits relevant to understand vegetation responses...

Data from: Rapid range expansion is not restricted by inbreeding in a sexually cannibalistic spider

Stefanie M. Zimmer, Henrik Krehenwinkel & Jutta M. Schneider
Few studies investigated whether rapid range expansion is associated with an individual's short-term fitness costs due to an increased risk of inbred mating at the front of expansion. In mating systems with low male mating rates both sexes share potential inbreeding costs and general mechanisms to avoid or reduce these costs are expected. The spider Argiope bruennichi expanded its range recently and we asked whether rapid settlement of new sites exposes individuals to a risk...

Data from: Oligonucleotide primers for targeted amplification of single-copy nuclear genes in apocritan Hymenoptera

Gerrit Hartig, Ralph S. Peters, Janus Borner, Claudia Etzbauer, Bernhard Misof & Oliver Niehuis
BACKGROUND: Published nucleotide sequence data from the mega-diverse insect order Hymenoptera (sawflies, bees, wasps, and ants) are taxonomically scattered and still inadequate for reconstructing a well-supported phylogenetic tree for the order. The analysis of comprehensive multiple gene data sets obtained via targeted PCR could provide a cost-effective solution to this problem. However, oligonucleotide primers for PCR amplification of nuclear genes across a wide range of hymenopteran species are still scarce. FINDINGS: Here we present a...

Data from: The nutritional balancing act of a large herbivore: an experiment with captive moose (Alces alces L)

Annika M. Felton, Adam Felton, David Raubenheimer, Stephen J. Simpson, Sophie J. Krizsan, Per-Ola Hedwall & Caroline Stolter
The nutrient balancing hypothesis proposes that, when sufficient food is available, the primary goal of animal diet selection is to obtain a nutritionally balanced diet. This hypothesis can be tested using the Geometric Framework for nutrition (GF). The GF enables researchers to study patterns of nutrient intake (e.g. macronutrients; protein, carbohydrates, fat), interactions between the different nutrients, and how an animal resolves the potential conflict between over-eating one or more nutrients and under-eating others during...

Biologic agents mediating matter-flow inside the porous igneous oceanic crust, Vesteris Seamount, Greenland Sea

Hinrich Schmid-Beurmann, Magnus Ivarsson, Wolfgang Bach, Wolf-Achim Kahl & Jörn Peckmann
Microorganisms within the lithosphere are biologic agents settling in niches inside the terrestrial and oceanic crust, populating the extreme environments of the deep biosphere. The fossil record of the permeable igneous oceanic crust, constructed out of primitive extrusive rock, opens a window into Earth’s early evolution and serves as an analogue for life in extraterrestrial worlds. In 2019, samples of highly porous basanites of Vesteris Seamount in the Greenland Sea were retrieved during a cruise...

Asesinas en series: violencia femenina en la televisión mexicana

Joachim Michael
pp. 68-85. Women who kill or take control of a drug cartel have moved into the center of interest of television producers. With series such as Mujeres asesinas or La reina del sur, television tries to show that it has already overcome the melodramatic tradition that qualifies women either as self-sacrificing victims or as ‘devourers’. These series propose that the female gender not only suffers the aggression of men or seduces them with their ‘own...

Geometric morphometric wing analysis represents a robust tool to identify female mosquitoes (Diptera: Culicidae) in Germany

Felix Gregor Sauer, Linda Jaworski, Laura Erdbeer, Anna Heitmann, Jonas Schmidt-Chanasit, Ellen Kiel & Renke Lühken
Accurate species identification is the prerequisite to assess the relevance of mosquito specimens, but is often hindered by missing or damaged morphological features. The present study analyses the applicability of wing geometric morphometrics as a low-cost and practical alternative to identify native mosquitoes in Germany. Wing pictures were collected for 502 female mosquitoes of five genera and 19 species from 80 sampling sites. The reliable species identification based on interspecific wing geometry of 18 landmarks...

Insights into the genetic basis of predator-induced response in Daphnia galeata

Verena Tams, Jana Helene Nickel, Anne Ehring & Mathilde Cordellier
Phenotypic plastic responses allow organisms to rapidly adjust when facing environmental challenges - these responses comprise morphological, behavioral but also life-history changes. Alteration of life-history traits when exposed to predation risk have been reported often in the ecological and genomic model organism Daphnia. However, the molecular basis of this response is not well understood, especially in the context of fish predation. Here, we characterized the transcriptional profiles of two Daphnia galeata clonal lines with opposed...

Primordial GATA6 macrophages function as extravascular platelets in sterile injury

Joel Zindel, Moritz Peiseler, Mokarram Hossain, Carsten Deppermann, Woo Yong Lee, Beat Haenni, Bas Surewaard, Daniel Candinas & Paul Kubes
Most multicellular organisms have a major body cavity that harbors immune cells. In primordial species like purple sea urchins, these cells perform phagocytic functions but are also crucial in repairing injuries. In mammals, the peritoneal cavity contains large numbers of resident GATA6+ macrophages, which may play a similar role. It is unclear how cavity macrophages suspended in the fluid phase (peritoneal fluid) identify and migrate towards injuries, however. Here, we show that cavity macrophages in...

Telychian Bryozoa, Matrix (Bryozoans from the lower Silurian (Telychian) Hanchiatien Formation from southern Chongqing, South China)

Andrej Ernst
Eight bryozoan species are described from the Hanchiatien Formation (lower Silurian, Telychian) of southern Chongqing, South China. Four species are new: the trepostomes Asperopora sinensis n. sp., Trematopora jiebeiensis n. sp., and Trematopora tenuis n. sp., and the fenestrate Moorephylloporina parvula n. sp. One species, a cystoporate Hennigopora sp. is described in open nomenclature. Moorephylloporina parvula n. sp. is eurytopic, occurring in all types of facies within the bioherms. Erect Moorephylloporina, Trematopora and Leioclema form...

Wild zebra finches are attracted towards acoustic cues from conspecific social groups

Corinna Adrian, Simon Griffith, Marc Naguib & Wiebke Schuett
Social information gathered by observing others often supplements personal information collected from direct interactions with the physical environment during decision making. Social information use may be particularly beneficial in harsh environments or if resources are distributed patchily, ephemeral and unpredictable, and hence difficult to locate. We experimentally tested the use of acoustic cues in wild zebra finches (Taeniopygia guttata) as they flew around their arid habitat as a way of locating conspecifics on the ground,...

Towards a stable global Noctuidae (Lepidoptera) taxonomy

Kevin Keegan, Jadranka Rota, Reza Zahiri, Alberto Zilli, Niklas Wahlberg, B. Christian Schmidt, J. Donald Lafontaine, Paul Goldstein & David Wagner
The family Noctuidae is one of the world’s most diverse, ecologically successful, and economically important animal lineages; with over 12,000 species in ~1150 genera. We inferred a phylogeny based on eight protein-coding genes (>6,400 base pairs) for the global fauna, greatly expanding upon previous attempts to stabilize the higher classification of Noctuidae by sampling 70 of the 76 widely recognized family-group taxa: 20 of the 21 subfamilies, 32 of the 35 tribes, and 18 of...

Plant diversity across small-scale boundaries

Pia Maria Eibes, Jens Oldeland, Severin David Howard Irl, Alina Twerski, Nicole Kühne & Ute Schmiedel
Questions: Habitat islands are often characterized by the presence of more or less sharp boundaries to adjacent matrix habitats. However, knowledge on boundaries of natural habitat islands is scarce, especially regarding patterns of beta diversity and its two underlying components: species turnover and nestedness. We therefore aim to quantify the effects of fine-scaled and sharp boundaries of quartz islands (quartz-gravel covered soils) on the different components of plant beta diversity and how they are linked...
