Data from: Threshold dynamics in plant succession after tree planting in agricultural riparian zones

Bérenger Bourgeois, Anne Vanasse, Eduardo González, Roxane Andersen & Monique Poulin
Trajectories of plant communities can be described by different models of plant succession. While a Clementsian (gradual continuum model) or Gleasonian approach (relay floristics model) has traditionally been used to inform restoration outcomes, alternative succession models developed recently may better represent restoration trajectories. The threshold dynamics succession model, which predicts an abrupt species turnover after an environmental threshold is crossed, has never been used in a restoration context. This model might, however, better describe shifts...

Data from: The role of selection and historical factors in driving population differentiation along an elevational gradient in an island bird

Joris A. M. Bertrand, Boris Delahaie, Yann X. C. Bourgeois, Thomas Duval, Ricardo García-Jiménez, Josselin Cornuault, Benoit Pujol, Christophe Thébaud & Borja Mila
Adaptation to local environmental conditions and the range dynamics of populations can influence evolutionary divergence along environmental gradients. Thus, it is important to investigate patterns of both phenotypic and genetic variation among populations to reveal the respective roles of these two types of factors in driving population differentiation. Here, we test for evidence of phenotypic and genetic structure across populations of a passerine bird (Zosterops borbonicus) distributed along a steep elevational gradient on the island...

Data from: Habituation in non-neural organisms: evidence from slime moulds

Romain P. Boisseau, David Vogel & Audrey Dussutour
Learning, defined as a change in behaviour evoked by experience, has hitherto been investigated almost exclusively in multicellular neural organisms. Evidence for learning in non-neural multicellular organisms is scant and only a few unequivocal reports of learning have been described in single celled organisms. Here we demonstrate habituation, an unmistakable form of learning, in the non-neural organism Physarum polycephalum. In our experiment, using chemotaxis as the behavioural output and quinine or caffeine as the stimulus,...

Data from: Predictable food supplies induce plastic shifts in avian scaled body mass

Noraine Salleh Hudin, Diederik Strubbe, Aimeric Teyssier, Liesbeth De Neve, Joël White, Geert P. J. Janssens & Luc Lens
Urbanization constitutes one of the most profound forms of land-use change and strongly affects global biodiversity and ecosystem functioning. Expansion of urban areas typically leads to species loss but may also induce more subtle changes in species dynamics through selection or plasticity. Using a dual correlative (field) and experimental (aviary) approach, we here show that free-ranging urban house sparrows in southern France were smaller and lighter than their rural counterparts after allometric scaling, whereas 2...

Data from: Local adaptation drives thermal tolerance among parasite populations: a common garden experiment

Elise Mazé-Guilmo, Simon Blanchet, Olivier Rey, Nicolas Canto & Géraldine Loot
Understanding the evolutionary responses of organisms to thermal regimes is of prime importance to better predict their ability to cope with ongoing climate change. Although this question has attracted interest in free-living organisms, whether or not infectious diseases have evolved heterogeneous responses to climate is still an open question. Here, we ran a common garden experiment using the fish ectoparasite Tracheliastes polycolpus, (i) to test whether parasites living in thermally heterogeneous rivers respond differently to...

Data from: Candidate gene analysis suggests untapped genetic complexity in melanin-based pigmentation in birds

Yann X. C. Bourgeois, Joris A. M. Bertrand, Boris Delahaie, Josselin Cornuault, Thomas Duval, Borja Milá & Christophe Thébaud
Studies on melanin-based color variation in a context of natural selection have provided a wealth of information on the link between phenotypic and genetic variation. Here, we evaluated associations between melanic plumage patterns and genetic polymorphism in the Réunion grey white-eye (Zosterops borbonicus), a species in which mutations on MC1R do not seem to play any role in explaining melanic variation. This species exhibits five plumage color variants that can be grouped into three color...

Data from: Intra-specific variability of hindlimb length in the palmate newt: an indicator of population isolation induced by habitat fragmentation?

Audrey Trochet, Hugo Le Chevalier, Boris Baillat, Laurent Barthe, Gilles Pottier, Olivier Calvez, Alexandre Ribéron & Simon Blanchet
Habitat fragmentation is one of the main drivers of global amphibian decline. Anthropogenic landscape elements can act as barriers, hindering the dispersal that is essential for maintaining gene flow between populations. Dispersal ability can be influenced by locomotor performance, which in turn can depend on morphological traits, such as hindlimb length (HLL) in amphibians. Here, we tested relationships between HLL and environmental variables—road types, forests and agricultural lands—among 35 sub-populations of palmate newts (Lissotriton helveticus)...
