Zupo, Talita [UNESP]; Daibes, Luis Felipe [UNESP]; Pausas, Juli G.; Fidelis, Alessandra [UNESP]Made available in DSpace on 2021-06-25T10:16:56Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Fundação Grupo Boticário de Proteção à Natureza; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Aim: Fire is a natural disturbance in many ecosystems throughout the world where plant populations can persist by the resprouting of individuals and/or by recruiting from seeds. We eval...

Wildfire management in Mediterranean-type regions: paradigm change needed
Moreira, Francisco; Ascoli, Davide; Safford, Hugh; Adams, Mark A.; Moreno, José M.; Cardoso Pereira, José Miguel; Catry, Filipe; Armest, JuanDuring the last decades, climate and land use changes led to an increased prevalence ofmegafires in Mediterranean-type climate regions (MCRs).Here, we argue that current wildfire management policies in MCRs are destined to fail.Focused on fire suppression, these policies largely ignore ongoing climate warming and landscape-scale buildup of fuels.The result is a ‘firefighting trap’ that contributes to ongoing fu...
Fire and legume germination in a tropical savanna: ecological and historical fa...
Daibes, L Felipe [UNESP]; Pausas, Juli G.; Bonani, Nathalia [UNESP]; Nunes, Jessika [UNESP]; Silveira, Fernando A O; Fidelis, Alessandra [UNESP]Made available in DSpace on 2019-10-06T15:50:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-07-08; BACKGROUND AND AIMS: In many flammable ecosystems, physically dormant seeds show dormancy-break patterns tied to fire, but the link between heat shock and germination in the tropical savannas of Africa and South America remains controversial. Seed heat tolerance is important, preventing seed mortality d...
Fire severity as a key factor in post-fire regeneration of Pinus pinaster (Ait....
Maia, Paula; Pausas, Juli G.; Vasques, Ana; Keizer, Jan JacobContext: Mediterranean pine woodlands are strongly affected by wildfires; however, there are knowledge gaps in the role of fire severity on Pinus pinaster Ait. regeneration. Objectives: The principal questions were: (a) does post-fire regeneration of Maritime Pine differ where canopies were consumed to a low vs. high degree and (b) which factors, besides fire severity, could explain these differences. Methods: ...
Cork oak vulnerability to fire: the role of bark harvesting, tree characteristi...
Catry, Filipe; Moreira, Francisco; Pausas, Juli G.; Fernandes, Paulo M.; Rego, Francisco Castro; Cardillo, Enrique; Curt, ThomasForest ecosystems where periodical tree bark harvesting is a major economic activity may be particularly vulnerable to disturbances such as fire, since debarking usually reduces tree vigour and protection against external agents. In this paper we asked how cork oak Quercus suber trees respond after wildfires and, in particular, how bark harvesting affects post-fire tree survival and resprouting. We gathered dat...
Coefficient shifts in geographical ecology: an empirical evaluation of spatial ...
Bini, L. Mauricio; Diniz-Filho, J. Alexandre F.; Rangel, Thiago F. L. V. B.; Akre, Thomas S. B.; Albaladejo, Rafael G.; Albuquerque, Fabio S.A major focus of geographical ecology and macro ecology is to understand the causes of spatially structured ecological patterns. However, achieving this understanding can be complicated when using multiple regressions, because the relative importance of explanatory variables, as measured by regression coefficients, can shift depending on whether spatially explicit or non-spatial modelling is used. However, the ...
