Continuous grazing disrupts desert grass-soil seed bank composition under variable rainfall
(Springer, 2021-02)
Long-term field studies help unveil mechanisms of grass soil seed bank (SSB) persistence and resilience. We wonder whether grazing is a disruptive force that changes grass SSB composition and size, while heavy rainfall is ...
Are all patches worth exploring? Foraging desert birds do not rely on environmental indicators of seed abundance at small scales
(BioMed Central, 2019-06)
Background: Consumers should show strong spatial preferences when foraging in environments where food availability is highly heterogeneous and predictable. Postdispersal granivores face this scenario in most arid areas, ...
Exploration and exploitation of foraging patches by desert sparrows: environmental indicators and local evaluation of spatially correlated costs and benefits
(Wiley, 2015-05)
Conventional evolutionary and behavioral reasoning expects foragers to show strong spatial preferences in environments with heterogeneous resource distribution. Moreover, consumers should benefit from exploiting the ...
Ecofisiologia evolutiva de sementes de Melastomataceae de campos rupestres
(Universidade Federal de Minas GeraisUFMG, 2011-08-16)
Seed biology plays a central role in plant ecology and evolution. The multiple benefits provided by seeds to seed plants were crucial in their rise and dominance throughout theglobe. Seeds are of primary significance for ...
