Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Considerações sobre o conceito de temperatura e de temperatura absoluta [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2006
The concept of temperature acquired by means of our contact interaction and the convenience of turning it less abstract by reference to the quantity of matter is discussed. It is then shown that the concept of 'molar thermal energy', numerically equal to the product of the gas constant by the absolute temperature, fulfills that end, expressing the ...
