Data from: Protected areas buffer the Brazilian semi-arid biome from climate change

Luis Hernán Acosta Salvatierra, Richard J. Ladle, Humberto Barbosa, Ricardo A. Correia & Ana Claudia Mendes Malhado
The Caatinga is a botanically unique semi-arid ecosystem in northeast Brazil whose vegetation is adapted to the periodic droughts that characterize this region. However, recent extreme droughts events caused by anthropogenic climate change have challenged its ecological resilience. Here, we evaluate how deforestation and protection status affect the response of the Caatinga vegetation to drought. Specifically, we compared vegetation responses to drought in natural and deforested areas as well as inside and outside protected areas,...

Data from: The anti-predator role of within-nest emergence synchrony in sea turtle hatchlings

Robson G. Santos, Hudson Tercio Pinheiro, Agnaldo Silva Martins, Pablo Riul, Soraya Christina Bruno, Fredric J. Janzen & Christos C. Ioannou
Group formation is a common behaviour among prey species. In egg-laying animals, despite the various factors that promote intra-clutch variation leading to asynchronous hatching and emergence from nests, synchronous hatching and emergence occurs in many taxa. This synchrony may be adaptive by reducing predation risk, but few data are available in any natural system, even for iconic examples of the anti-predator function of group formation. Here, we show for the first time that increased group...

Extensive introgression at late stages of species formation: Insights from grasshopper hybrid zones

Linda Hagberg, Enrique Celemín, Iker Irisarri, Oliver Hawlitschek, José Bella, Tamí Mott & Ricardo Pereira
The process of species formation is characterised by the accumulation of multiple reproductive barriers. The evolution of hybrid male sterility, or Haldane’s rule, typically characterises later stages of species formation, when total reproductive isolation is strongest. Yet, understanding how quickly reproductive barriers evolve and their consequences for maintaining genetic boundaries between emerging species remains a challenging task because it requires studying taxa that hybridise in nature. Here, we address these questions using the meadow grasshopper...

Data from: Response of Prochilodus nigricans to flood pulse variation in the central Amazon

Peter B. Bayley, Leandro Castello, Vandick S. Batista & Nidia N. Fabré
The influence of the flood pulse on fish populations has been posited, but infrequently tested or quantified. Here, we tested the effect of habitat on population size, using Prochilodus nigricans as a case study species. Floodplain habitat was based on the littoral zone area occupied by P. nigricans to feed. The magnitude of this habitat in each hydrological year, the moving littoral (ML), was expressed as the sum of daily littoral areas during the advancing...
