Germination response of common annual and perennial forbs to heat shock and smoke treatments in the Chaco Serrano, central Argentina
(Wiley Blackwell Publishing, Inc, 2018-08)
Fire is a key ecological factor affecting plant dynamics. In the last few decades, fire occurrence in the Chaco region has increased noticeably, challenging the adaptive capacity of plants to regenerate after a fire. ...
Seed tolerance to post-fire temperature fluctuation of Cerrado legume shrubs with micromorphological implications
(2021-02-01)
Multiple environmental cues may break seed physical dormancy (PY) in fire-prone ecosystems, but disentangling the roles of such cues remains challenging. Current research has mostly focused on the role of high temperatures ...
Alterations following a fire in a forest community of Alto Rio Xingu
(Elsevier B.V., 2014)
Response of hardwood tree regeneration to surface fires, western Chaco region, Argentina
(2014-08-15)
We assessed the response of seedlings and pole-sized individuals of Aspidosperma quebracho-blanco Schlecht., Schinopsis lorentzii (Griseb.) Engler and Ziziphus mistol Griseb. to surface fires. We assessed traits of fire ...
Perda de originalidade e extinções simuladas de espécies arbustivo-arbóreas de cerrado
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2012-03-02)
Originality measures how different a given species is from all other species regarding either their phylogenetic history or functional traits and may be used to assign conservation priorities. This dissertation is divided ...
Linking thermo-tolerances of the highly invasive little fire ant, Wasmannia auropunctata, to its current and potential distribution. Biological Invasions
(Springer, 2019-12)
Species distribution models based on the correlation of bioclimatic variables and presence spatial data-points are useful for recognizing species habitat suitability. However, they have limitations in predicting the ...
Forest stability during the early and late Holocene in the igapó floodplains of the Rio Negro, northwestern Brazil
(Cambridge University Press, 2018)
Located at the northwestern part of the Amazon basin, Rio Negro is the largest black-water river in the world and is one of the poorest studied regions of the Amazon lowlands. In the middle-upper part of the Rio Negro were ...
Heat shock effects on germination and seed survival of five woody species from the Chaco region
(Elsevier Gmbh, 2021-02)
In tropical dry forests, fire is a common disturbance and seed traits may drive regeneration of plant populations during these events. In this study, we aimed to (i) investigate whether the seed coat and/or fruit endocarp ...
