MÉTODOS DE SECAGEM DE AMOSTRAS DE FOLHAS DE CAPIM BRACHIÁRIA, CANA-DE-AÇÚCAR E GOIABEIRA NOS TEORES DE MACRONUTRIENTES

open access: yesColloquium Agrariae, 2012
A secagem de amostras de folhas em forno microondas pode ser promissora se não afetar os teores dos nutrientes nas amostras, comparada ao método convencional em estufa.

Foliar Nutrient Dynamics and Foliar Resorption in Quercus brantii Lindley along an Elevational Gradient

open access: yesPakistan Journal of Biological Sciences, 2007
Foliar mass per area (mg dm(-2)) -based nitrogen and phosphorus concentrations, specific leaf mass (mg dm(-2)) and absolute and proportional resorption in Quercus brantii was investigated along a topographic gradient from 450 to 850 m altitude. Foliar N and P concentrations in Q.

Prescribed burning shows minor impacts on black pine needle terpenes and pine processionary moth larval survival

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results highlight that prescribed burning in sub‐Mediterranean pine forests does not affect their resistance to PPM in the short term, either positively or negatively, indicating that it can be implemented to reduce wildfire hazard without influencing forest susceptibility to future PPM outbreaks.

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

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 ...

Adubação nitrogenada via substrato no cultivo de bromélia

open access: yesOrnamental Horticulture, 2015
Um dos motivos do extrativismo predatório de bromélias é o reduzido número de informações a cerca das técnicas de cultivo dessas plantas, principalmente em relação à adubação.

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.
