Plastid introgression and evolution of African miombo woodlands: new insights from the plastome-based phylogeny of Brachystegia trees

Arthur Boom, Jérémy Migliore, Esra Kaymak, Pierre Meerts & Olivier Hardy
Aim: Miombo woodlands form a characteristic vegetation type covering 2.7 million km2 in southern and eastern Africa. Despite their wide geographical extent, their origin, floristic and spatial evolution through time remain understudied. To fill this gap, we studied the evolution of Brachystegia trees, one of the most representative genera of these woodlands (20 species), also represented in Guineo-Congolian rain forests (8 species). Location: Tropical Africa, Guineo-Congolian forests and Zambezian savannahs. Methods: We used a genome...

Timing uncertainty in collective risk dilemmas encourages group reciprocation and polarization

Elias Fernandez Domingos, Jelena Grujić, Francisco C. Santos, Juan C. Burguillo Rial, Georg Kirchsteiger, Francisco C. Santos & Tom Lenaerts
Social dilemmas are often shaped by actions involving uncertain returns only achievable in the future, such as climate action or voluntary vaccination. In this context, uncertainty may produce non-trivial effects. Here, we assess experimentally — through a collective risk dilemma — the effect of timing uncertainty, i.e. how uncertainty about when a target needs to be reached affects the participants’ behaviours. We show that timing uncertainty prompts not only early generosity but also polarised outcomes,...

Robustness of consensus is independent from preference diversity among group members in the American cockroach (Periplaneta american)

Mariano Calvo Martín, Max Eeckhout, Jean-Louis Deneubourg & Stamatios Nicolis
Collective choices and consensus resulting from the competition of positive feedbacks, are the subject of numerous studies. However, how the interindividual diversity of preferences among the group members affects these dynamics is usually overlooked apart from vertebrates based studies. Gregarism is a useful model for studying how the interindividual diversity of preferences affects the collective choices and consensus. The decision-making of three types of groups of the cockroach Periplaneta americana is tested in a choice...

How did subterranean amphipods cross the Adriatic Sea? Phylogenetic evidence for the dispersal-vicariance interplay mediated by marine regression-transgression cycles

Teo Delić, Fabio Stoch, Spela Borko, Jean-Francois Flot & Cene Fišer
Aim: We tested the hypothesis that historical marine regression-transgression cycles shaped the distribution patterns of subterranean amphipods through repeated cycles of dispersal and vicariance against the hypothesis that subterranean amphipods colonized both sides of the Adriatic Sea independently. Location: Western Balkan Peninsula, Adriatic Sea Islands and Apennine Peninsula, Europe Taxon: A clade of freshwater subterranean amphipods, genus Niphargus (Crustacea: Amphipoda). Methods: The taxonomic structure of the studied clade was revised using unilocus species delimitations. Timeframe...

Diurnal foraging ant–tree co-occurrence networks are similar between canopy and understorey in a Neotropical rain forest

Reuber Antoniazzi, Jose Garcia-Franco, Milan Janda, Maurice Leponce & Wesley Dáttilo
Discussion of the vertical stratification of organisms in tropical forests has traditionally focused on species distribution. Most studies have shown that, due to differences in abiotic conditions and resource distribution, species can be distributed along the vertical gradient according to their eco-physiological needs. However, the network structure between distinct vertical strata remains little-explored. To fill this gap in knowledge, we used baits to sample ants in the canopy and understorey trees of a Mexican tropical...

Data from: The origin of the legumes is a complex paleopolyploid phylogenomic tangle closely associated with the Cretaceous-Paleogene (K-Pg) mass extinction event

Erik Koenen, Dario Ojeda, Freek Bakker, Jan Wieringa, Catherine Kidner, Olivier Hardy, Toby Pennington, Patrick Herendeen, Anne Bruneau & Colin Hughes
The consequences of the Cretaceous-Paleogene (K-Pg) boundary (KPB) mass extinction for the evolution of plant diversity remain poorly understood, even though evolutionary turnover of plant lineages at the KPB is central to understanding assembly of the Cenozoic biota. The apparent concentration of whole genome duplication (WGD) events around the KPB may have played a role in survival and subsequent diversification of plant lineages. To gain new insights into the origins of Cenozoic biodiversity, we examine...

Mitonuclear mismatch alters performance and reproductive success in naturally-introgressed populations of a montane leaf beetle

Nathan Rank, Nathan E Rank, Patrick Mardulyn, Sarah J Heidl, Kevin T Roberts, Nicolas A Zavala, John T Smiley & Elizabeth P Dahlhoff
Coordination between nuclear and mitochondrial genomes is critical to metabolic processes underlying animals' ability to adapt to local environments, yet consequences of mitonuclear interactions have rarely been investigated in populations where individuals with divergent mitochondrial and nuclear genomes naturally interbreed. Genetic variation in the leaf beetle Chrysomela aeneicollis was assessed along a latitudinal thermal gradient in California's Sierra Nevada. Variation at mitochondrial cytochrome oxidase II (COII) and the nuclear gene phosphoglucose isomerase (PGI) shows concordance...

Data from: Do people imitate when making decisions? - evidence from a spatial prisoners dilemma experiment

Jelena Grujic & Tom Lenaerts
How do people decide which action to take? This question is best answered using Game Theory, which has proposed a series of decision mechanisms that people potentially use. In network simulations, wherein games are repeated and payoff differences can be observed, those mechanisms rely often on imitation of successful behavior. Surprisingly, little to no evidence has been provided about whether, how and what people actually use to alter their actions in that context. By comparing...

Data from: Evolution and epidemic spread of SARS-CoV-2 in Brazil

Darlan S. Candido, Ingra M. Claro, Jaqueline G. De Jesus, William M. Souza, Filipe R. R. Moreira, Simon Dellicour, Thomas A. Mellan, Louis Du Plessis, Rafael H. M. Pereira, Flavia C. S. Sales, Erika R. Manuli, Julien Thézé, Luiz Almeida, Mariane T. Menezes, Carolina M. Voloch, Marcilio J. Fumagalli, Thaís M. Coletti, Camila A. M. Da Silva, Mariana S. Ramundo, Mariene R. Amorim, Henrique H. Hoeltgebaum, Swapnil Mishra, Mandev S. Gill, Luiz M. Carvalho, Lewis F. Buss … & Nuno R. Faria
Brazil currently has one of the fastest growing SARS-CoV-2 epidemics in the world. Owing to limited available data, assessments of the impact of non-pharmaceutical interventions (NPIs) on virus spread remain challenging. Using a mobility-driven transmission model, we show that NPIs reduced the reproduction number from >3 to 1–1.6 in São Paulo and Rio de Janeiro. Sequencing of 427 new genomes and analysis of a geographically representative genomic dataset identified >100 international virus introductions in Brazil....

Microsatellite genotypes and ITS2 DNA sequence data for Seriatopora hystrix

Rosa Maria Van Der Ven, Jean-François Flot, Carol Buitrago-López & Marc Kochzius
Coral reefs provide essential goods and services but are degrading at an alarming rate due to local and global anthropogenic stressors. The main limitation that prevents the implementation of adequate conservation measures is that connectivity and genetic structure of populations are poorly known. Here, the genetic diversity and connectivity of the brooding scleractinian coral, Seriatopora hystrix were assessed at two scales by genotyping ten microsatellite markers for 356 individual colonies. Seriatopora hystrix showed high differentiation,...
