We study the effects of central bank communication about financial stability on individuals' expectations and risk-taking. Using a randomized information experiment, we show that causally affects beliefs investment behavior, consistent with an channel communication. Individuals receiving warning from expect higher probability crisis reduce their demand for risky assets. This reduction is driven...

To evaluate the adaptive value of the widening of the bilobed tarsi that has paralleled the tremendous radiation of the staphylinid genus Stenus, the performance of slender versus wide tarsi has been evaluated in two different contexts: (i) locomotion on the surface of water, and (ii) climbing on vertical (plant) surfaces. Contact angle measurements at the underside of the tarsi have revealed t...

Sequencing of vertebrate genomes permits changes in distinct protein families, including gene gains and losses, to be ascribed to lineage-specific phenotypes. A prominent example of this is the large-scale duplication of beta-keratin genes in the ancestors of birds, which was crucial to the subsequent evolution of their beaks, claws, and feathers. Evidence suggests that the shell of Pseudomys n...

The lengths of the digital bones of the fore- and hind-limbs obtained post mortem from 40 cattle of different ages were measured using digital radiographs. The lengths of the individual digital bones and the overall length of the digit were determined using computer software. The lateral metacarpal/metatarsal condyle, and lateral P1 and P2 were significantly longer than their medial counterpart...

The aim was to describe variation in length of the dorsal hoof wall in contact with the dermis for cows on a single farm, and hence, derive minimum appropriate claw lengths for routine foot trimming. The hind feet of 68 Holstein-Friesian dairy cows were collected post mortem, and the internal structures were visualised using x-ray µCT. The internal distance from the proximal limit of the wall h...

Substrate use and locomotory behavior of mammals are typically reflected in external characteristics of the forefeet, such as the relative proportions of the digits and claws. Although skeletal anatomy of the forefeet can be more informative than external characters, skeletons remain rare in systematic collections. This is particularly true for the Myosoricinae (Eulipotyphla: Soricidae), a smal...

Grooming claws are present on the second pedal digits of strepsirhines and on the second and third pedal digits of tarsiers. However, their presence in New World monkeys is often overlooked. As such, the absence of a grooming claw is generally considered an anthropoid synapomorphy. This study utilizes a quantitative multivariate analysis to define grooming claw morphology and document its prese...

Insects are successful terrestrial organisms able to locomote over a wide range of obstacles and substrates. This study investigated how foot morphology (tarsal structure) correlates with substrate adhesion and ecological niche in the Madagascan hissing cockroach, Gromphadorhina portentosa Schaum (Blattaria: Blaberidae). Using light and scanning electron microscopy, the morphology of the differ...

The Front Cover shows an “O2 grasshopper” captured by two “Copper scorpions” using their strong claws and tails (outer-sphere hydrogen bonds). As the key intermediate in biological oxygenation, trans-1,2-peroxodicopper adduct was mimicked a variety of molecular copper complexes. structure-activity models hydrogen-bond-assisted tetradentate copper(I) chloride complexes were established, fundamen...

To contribute to have a better understanding of the symbolic or not use of certain items by Neanderthals, this work presents new evidence of the deliberate removal of raptor claws occurred in Mediterranean Europe during the recent phases of the Mousterian. Rio Secco Cave in the north-east of Italy and Mandrin Cave in the Middle Rhône valley have recently produced two golden eagle pedal phalange...
