Leading-edge vortex lifts swiftsJ J Videler
Department of Marine Biology Experimental Marine Zoology Group, Groningen University, Post Office Box 14, 9750 AA, Haren, Netherlands
Science 306:1960-2. 2004
..We suggest that the flow around the arm-wings of most birds can remain conventionally attached, whereas the swept-back hand-wings generate lift with leading-edge vortices...
Hydrodynamics of unsteady fish swimming and the effects of body size: comparing the flow fields of fish larvae and adultsU K Müller
Department of Marine Biology, University of Groningen, The Netherlands
J Exp Biol 203:193-206. 2000
..The rapid decrease in vortex circulation and the severe reduction in the coasting distance due to viscous drag contribute to the high cost that larvae - unlike adult fish - face when using a burst-and-coast swimming style...
Photic entrainment of circadian activity patterns in the tropical labrid fish Halichoeres chrysusM P Gerkema
Zoological Laboratory, University of Groningen, Haren, Netherlands
Chronobiol Int 17:613-22. 2000
..This response allows photic entrainment as described here in the yellow wrasse...
How the body contributes to the wake in undulatory fish swimming: flow fields of a swimming eel (Anguilla anguilla)U K Müller
Department of Marine Biology, University of Groningen, The Netherlands
J Exp Biol 204:2751-62. 2001
..Earlier recordings show that eels also generate a wake reflective of maximum swimming efficiency. The combined findings suggest that eels can modify their body wave to generate wakes that reflect their propulsive mode...
Burrow ventilation in the tube-dwelling shrimp Callianassa subterranea (Decapoda: thalassinidea). I. Morphology and motion of the pleopods, uropods and telsonE J Stamhuis
Department of Marine Biology, University of Groningen, PO Box 14, The Netherlands
J Exp Biol 201:2151-8. 1998
..The motion patterns of PP2 and PP3 could be modelled by assigning pure sinusoids with a 120 degrees phase shift and a rostro-caudal ranking to the three pairs of pleopods...
Burrow ventilation in the tube-dwelling shrimp callianassa subterranea (Decapoda: thalassinidea). II. The flow in the vicinity of the shrimp and the energetic advantages of a laminar non-pulsating ventilation currentE J Stamhuis
Department of Marine Biology, University of Groningen, PO Box 14, The Netherlands
J Exp Biol 201:2159-70. 1998
..The results suggested that, by constricting the tube and keeping the flow steady, C. subterranea saves on ventilation costs by a factor of up to six compared with oscillatory flow in a tube without the tail-fan constriction...
Burrow ventilation in the tube-dwelling shimp Callianassa subterranea (Decapoda: thalassinidea). III. Hydrodynamic modelling and the energetics of pleopod pumpingE J Stamhuis
Department of Marine Biology, University of Groningen, PO Box 14, The Netherlands
J Exp Biol 201:2171-81. 1998
..Furthermore, the moment of added mass shedding, the distance between adjacent pleopods, the number of pleopods and the total tube drag were also varied to evaluate their effects...
How swifts control their glide performance with morphing wingsD Lentink
Experimental Zoology Group, Wageningen University, 6709 PG Wageningen, The Netherlands
Nature 446:1082-5. 2007
..11), thus our model can explain this choice for a resting behaviour. Morphing not only adjusts birds' wing performance to the task at hand, but could also control the flight of future aircraft...
