To elucidating

Its name is based on the fact that it spent more of its life in caves than its closest present-day relative, the brown bear ().

First appearing in the fossil record some 300,000 years ago, the cave bear vanished between 20,000 and 25,000 years ago during the Last Glacial Maximum.

Male cave bears had estimated average weights between 400 and 500 kilograms whereas female cave bears were smaller, with average weights ranging from 225 to 250 kilograms.

ist zum einen, eine Analogie zwischen kurzzeitiger instationärer Wärmeleitung in einer ebenen Platte und stationärer Leitung in einer geraden Rechteckrippe gleichbleibenden Querschnitts aufzuzeigen, zum anderen sollen analytische Näherungslösungen der instationären Wärmeleitungsgleichung für kurze Zeiten hergeleitet werden, wobei eine Platte mit gleichförmiger Anfangstemperatur unter Aufprägung einer gleichförmigen Oberflächentemperatur (Dirichletsche Randbedingung) zugrunde gelegt sei.

Lead (Pb) is widely used in consumer products as an alloy and pigment despite its well-known serious toxic effects.

The brown bear has an EQ of 0.83 and the (small-bodied) Malayan sun bear has an EQ of 1.31. Veitschegger interprets this as evidence that the increase in body size during the evolution of the cave bear did not correlate with change in brain size.

However, the proportionately small brain may also reflect a less energy-rich diet (as other bears consume more animal protein) and a highly seasonal environment that probably required longer periods of hibernation.

Antidepressant drugs are widely prescribed, but response rates after 3 months are only around one-third, explaining the importance of the search of objectively measurable markers predicting positive treatment response.

These markers are being developed in different fields, with different techniques, sample sizes, costs, and efficiency.Several bear species that today only occur in America or in Asia have hybridized in their evolutionary history, researchers have discovered.The Beringia land bridge, which in former times connected ...Veitschegger considers it likely that cave bears gave birth to numerous cubs after long gestation periods.His examination of the microscopic structure of their leg bones indicates that these extinct bears grew more rapidly but attained sexual maturity later in life than other bear species.Marie-Laure CLERY-MELIN has no conflicts of interest to declare.
