Quantity over quality? Prey-field characteristics influence the foraging decisions of little penguins (Eudyptula minor)

Royal Society Open Science, 2022
Quantifying prey characteristics is important for understanding the foraging behaviour of predators, which ultimately influence the structure and function of entire ecosystems. However, information available on prey is often at magnitudes which cannot be

Extractives and energetic properties of wood and charcoal

Revista Árvore, 2014
Charcoal production stands out as a raw material for the production of renewable energy. To assess wood quality in energy terms, studies have focused more on the holocellulose and lignin content than on the role of extractives.
