How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Utilização de surfactantes, na polpação kraft de madeira de eucalipto, como auxiliar na remoção de extrativos lipofílicos Surfactant utilization in kraft pulping of eucalyptus wood to improve lipophilic extractives removal

open access: yesRevista Árvore, 2004
Problemas de deposição de "pitch" em fábricas de celulose e de papel são atribuídos aos extrativos lipofílicos existentes na madeira. Uma das maneiras mais eficientes de controlar essa deposição é através da remoção de seus precursores do sistema, logo ...

Environmental and human factors shape the trophic ecology of a widespread marine predator

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1784-1799, September 2025.
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

Chemical composition and dry matter digestibility of sugar cane oxide treated with calcium

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
The aim of this study was to identify the most adequate level of calcium oxide (CaO) in the treatment of sugar cane by evaluating the chemical composition and in vitro digestibility of dry matter. The sugar cane was homogenized with CaO levels 0, 0.75, 1.

Survival of Eurasian lynx in the human‐dominated landscape of Europe

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Survival and cause‐specific mortality rates are vital for evidence‐based population forecasting and conservation, particularly for large carnivores, whose populations are often vulnerable to human‐caused mortalities. It is therefore important to know the relationship between anthropogenic and natural mortality causes to evaluate whether they ...
