The Bering Land Bridge (BLB) last connected Eurasia and North America during the Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations of a once wide-ranging group, the caballine horses (Equus spp.). Using a panel of 187 mitochondrial and...

Behavioral and chemical composition data for: Maternal and personal information mediates the use of social cues about predation risk

Laurane Winandy & Julien Cote
Organisms can gain information about predation risks from their parents, their own personal experience, and their conspecifics and adjust their behavior to alleviate these risks. These different sources of information can, however, provide conflicting information due to spatial and temporal variation of the environment. This raises the question of how these cues are integrated to produce adaptive antipredator behavior. We investigated how common lizards (Zootoca vivipara) adjust the use of conspecific cues about predation risk...

Démasquer le masque

Eric Remy
Il est de ces objets qui, sur une période particulière de notre histoire et de notre vie, portent en eux la société toute entière. Il y a peu de temps, c’est le gilet jaune qui s’est ancré dans l’imaginaire collectif national. Avec la crise sanitaire de la Covid19, c’est le masque qui est devenu un objet iconique de la culture matérielle contemporaine. Sans prétendre à l’exhaustivité, nous revenons sur quelques éléments de lecture nous permettant...

Tree communities and soil properties influence fungal community assembly in neotropical forests

Heidy Schimann, Jason Vleminckx, Christopher Baraloto, Julien Engel, Gaelle Jaouen, Eliane Louisanna, Sophie Manzi, Audrey Sagne & Mélanie Roy
The influence exerted by tree communities, topography and soil chemistry on the assembly of macrofungal communities remains poorly understood, especially in highly diverse tropical forests. Here, we used a large dataset that combines inventories of macrofungal Basidiomycetes fruiting bodies, tree species composition and measurements for 16 soil physico-chemical parameters, collected in 34 plots located in four sites of lowland rainforests in French Guiana. Plots were established on three different topographical conditions: hilltop, slope and seasonally...

Dataset of biomechanical effects of the addition of a precision constraint on a collective load carriage task

Nour Sghaier, Guillaume Fumery, Vincent Fourcassié, Nicolas Alain Turpin & Pierre Moretto
Team lifting is a complex and collective motor task that possesses both motor and cognitive components. We study the collective load carriage adaptation due to an additional accuracy constraint. Ten dyads performed a first condition in which they collectively transported a load (CC), and a second one in which they transported the same load while maintaining a ball in a target position on its top (PC). The recovery-rate, amplitude, and period of the center-of-mass of...
