Data supporting: Success of post-fire plant recovery strategies varies with shifting fire seasonality
<p><span>Wildfires are increasing in size and severity and fire seasons are lengthening, largely driven by climate and land use change.</span> <span>Many plant species from fire prone ecosystems are adapted to specific fire regimes corresponding to historical conditions and shifts beyond these bounds may have severe impacts on vegetation recovery and long-term species persistence</span><span>. Here, we conduct a meta-analysis of field-based studies across different vegetation types and climate regions to investigate how post-fire plant recruitment, reproduction and survival are affected by fires that occur outside of the historical fire season. We find that fires outside of the historical fire season may lead to decreased post-fire recruitment for many species, particularly obligate seeding species. Conversely, we find a general increase of post-fire survival in resprouting species. </span><span>Our results highlight the trade-offs that exist when considering the effects of changes in the seasonal timing of fire, an already present aspect of climate-related global fire regime change. </span></p>

Data from: The diversity of post-fire regeneration strategies in the cerrado ground layer
<p>1. Disentangling species strategies that confer resilience to natural disturbances is key to conserving and restoring savanna ecosystems. Fire is a recurrent disturbance in savannas, and savanna vegetation is highly adapted to, and often dependent on fire. However, although the woody component of tropical savannas is well studied, we still do not understand how ground-layer plant communities respond to fire, limiting conservation and management actions.</p> <p>2. We investigated the effects of prescribed fire on community structure and composition, and evaluated which traits are involved in plant community regeneration after fire in the cerrado ground layer. We assessed traits related to species persistence and colonization capacity after fire, including resprouter type, underground structure, fire-induced flowering, regeneration strategy and growth form. We searched for functional groups related to response to fire, to shed light on the main strategies of post-fire recovery among species in the ground layer.</p> <p>3. Fire changed ground-layer community structure and composition in the short term, leading to greater plant species richness, population densities, and increasing bare soil, compared with unburned communities. Eight months after fire, species abundance did not differ from pre-disturbance values for 86% of the species, demonstrating the resilience of this layer to fire. Only one ruderal species was disadvantaged by fire and 13% of the species benefited. Rapid recovery of soil cover by native vegetation in burned areas was driven by species with high capacity to resprout and spread vegetatively. Recovery of the savanna ground-layer community, as a whole, resulted from a combination of different species traits. We summarized these traits into five large groups, encompassing key strategies involved in ground layer regeneration after fire.</p> <p>Synthesis: Fire dramatically changes the ground layer of savanna vegetation in the short term, but the system is highly resilient, quickly recovering the pre-fire state. Recovery involves different strategies, which we categorized into five functional groups of plant species: grasses, seeders, bloomers, undergrounders, and resprouters. Knowledge of these diverse strategies should be used as a tool to assess conservation and restoration status of fire-resilient ecosystems in the cerrado.</p>

Figure 1 in Short Note Multiple paternity in the pueriparous North African fire salamander, Salamandra algira, supports polyandry as a successful mating strategy in low fecundity Salamandra lineages
Figure 1. (a) Distribution of both species displaying reproductive polymorphism, Salamandra salamandra (in blue) and Salamandra algira (in green). In red, the area of occurrence of pueriparity within each species. Values next to each pueriparous nuclei denote the frequency of multiple paternity. (b) Detail of the western-most distribution area of S. algira where the pueriparous lineage occurs (in red). The box shows the number of fathers and the proportion of the offspring sired by each male for all four studied females. Numbers in brackets are clutch size in each female.
