In vivo quantification of mechanical properties of caudal fins in adult zebrafish

Puri, Sahil ; Aegerter-Wilmsen, Tinri ; Jaźwińska, Anna ; Aegerter, Christof M.

In: Journal of Experimental Biology, 2018, vol. 221, no. 4, p. jeb171777

Skip to Next SectionThe caudal fins of adult zebrafish are supported by multiple bony rays that are laterally interconnected by soft interray tissue. Little is known about the fin's mechanical properties that influence bending in response to hydrodynamic forces during swimming. Here, we developed an experimental setup to measure the elastic properties of caudal fins in vivo by applying...

Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs

Foth, Christian ; Rauhut, Oliver W. M.

In: BMC Evolutionary Biology, 2017, vol. 17, p. 236

Archaeopteryx is an iconic fossil that has long been pivotal for our understanding of the origin of birds. Remains of this important taxon have only been found in the Late Jurassic lithographic limestones of Bavaria, Germany. Twelve skeletal specimens are reported so far. Archaeopteryx was long the only pre-Cretaceous paravian theropod known, but recent discoveries from the Tiaojishan...

Functional organization of the medial temporal lobe memory system following neonatal hippocampal lesion in rhesus monkeys

Chareyron, Lo?c J. ; Lavenex, Pamela Banta ; Amaral, David G. ; Lavenex, Pierre

In: Brain Structure and Function, 2017, vol. 222, no. 9, p. 3899–3914

Hippocampal damage in adult humans impairs episodic and semantic memory, whereas hippocampal damage early in life impairs episodic memory but leaves semantic learning relatively preserved. We have previously shown a similar behavioral dissociation in nonhuman primates. Hippocampal lesion in adult monkeys prevents allocentric spatial relational learning, whereas spatial learning persists...

The discovery of wild date palms in oman reveals a complex domestication history involving centers in the middle east and africa

Gros-Balthazard, Muriel ; Galimberti, Marco ; Kousathanas, Athanasios ; Newton, Claire ; Ivorra, Sarah ; Paradis, Laure ; Vigouroux, Yves ; Carter, Robert ; Tengberg, Margareta ; Battesti, Vincent ; Santoni, Sylvain ; Falquet, Laurent ; Pintaud, Jean-Christophe ; Terral, Jean-Frédéric ; Wegmann, Daniel

For many crops, wild relatives constitute an extraordinary resource for cultivar improvement [1, 2] and also help to better understand the history of their domestication [3]. However, the wild ancestor species of several perennial crops have not yet been identified. Perennial crops generally present a weak domestication syndrome allowing cultivated individuals to establish feral populations...
