Interactions between the internal regulation and environment drive biophysiological patterns of amphibians. It is well known phenomenon that newts in northern hemisphere are tend to have hibernation strategies winter seasons. However, activity record for quite rare. Therefore, we would like report two cases from Anatolia, Turkey via newt species: The banded (Ommatotriton ophryticus) Ordu Balkan...

weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. this paper is connected with the development of the discharge coefficient measurement. in the present study four different weirs in different height are considered for validation purp...

The amount of wave overtopping at coastal structures such as vertical caisson breakwaters is strongly dependent on the angle attack. reducing effects oblique waves compared to perpendicular attack has been studied by means three-dimensional basin tests. In these physical model tests breakwater exposed conditions with angles between and very (i.e. 0°–75° in steps 15°). Short-crested long-crested...

A comparison of brain size and brain composition was made between two uncrested duck breeds and Crested Ducks (CR) and between CR individuals that do possess crests and those that do not have the crest. Domestic ducks of the breed CR have allometrically larger brains than uncrested duck breeds. The crest inserts on a cushion of fat and connective tissue that is partly nourished by brain vessels...

Evolutionary biologist Michael Shapiro and his team made international headlines in 2013 when they found that a prominent change in pigeon plumage, head crests, could be traced to a mutation in a single gene. Now, in the new advanced online edition of Molecular Biology and Evolution (Vickrey et al. 2015), the research team has found an almost exact repeat in the evolutionary playbook. A mutatio...
