Temporal and spatial variation in the Nazaré canyon (Western Iberian margin): I...
Ramalho, Sofia; Adão, Helena; Kiriakoulakis, K.; Wolff, G.A.; Vanreusel, A.; Ingels, J.The Nazaré canyon on the Portuguese Margin (NE Atlantic) was sampled during spring-summer for three consecutive years (2005 - 2007), permitting the first inter-annual study of the meiofaunal communities at the Iberian Margin at two abyssal depths (~3500 m and ~4400 m). Using new and already published data, the meiofauna standing stocks (abundance and biomass) and nematode structural and functional diversity we...
Europe's Grand Canyon Nazaré Submarine Canyon
Tyler, P; Amaro, T; Arzola, R; Cunha, MR; de Stigter, H; Gooday, A; Huvenne, V; Ingels, J; Kiriakoulakis, K; Lastras, G; Masson, D; Oliveira, AThe Nazare submarine canyon extends similar to 210 km westward from the coast of Portugal, down to a water depth of > 4300 m. The considerable habitat heterogeneity found throughout the canyon is affected by strong currents and high turbidity, especially in the upper parts of the canyon. The canyon morphology comprises steep slopes, scarps, terraces, and overhangs, and a deeply incised thalweg is found in the l...
Opportunistic adaptations to man-induced habitat changes by some South American...
INGELS,J.; ONIKI,Y.; WILLIS,E. O.We describe the opportunistic adaptation to man-induced changes in the habitats of six neotropical Caprimulgidae. Habitats created by those changes, and similar to their original and usual ones, are readily occupied by these nightjars. The occasional invasion of urban environments ("urbanization") is the most recent and most remarkable behavioural adaptation.
