FISIOLOGIA DA GERMINAÇÃO DE SEMENTES DE Dalbergia nigra (Vell.) Allemão ex Benth. SOB DIFERENTES TEMPERATURAS E TEMPOS DE EXPOSIÇÃO

open access: yesRevista Árvore, 2015
A germinação de sementes é dependente de fatores abióticos, sendo a temperatura um dos principais, cuja influência, em condições extremas, causa danos às sementes.

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Proximity effect and strong coupling superconductivity in nanostructures built with an STM

open access: yes, 2001
We present high resolution tunneling spectroscopy data at very low temperatures on superconducting nanostructures of lead built with an STM. By applying magnetic fields, superconductivity is restricted to length scales of the order of the coherence ...

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

open access: yesNew Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Um cimento mais sustentável frente a um ataque severo por sulfatos [PDF]

open access: yes, 2007
A necessidade de encontrar um cimento plenamente resistente aos sulfatos e que também seja ambientalmente sustentável levou a que se analisasse o comportamento de um cimento sulfoaluminato-belítico (SAB) frente a um ataque severo por sulfato de sódio e ...

Evolution of the local superconducting density of states in ErRh$_4$B$_{4}$ close to the ferromagnetic transition

open access: yes, 2009
We present local tunneling spectroscopy experiments in the superconducting and ferromagnetic phases of the reentrant superconductor ErRh$_4$B$_{4}$. The tunneling conductance curves jump from showing normal to superconducting features within a few mK ...
