Climate change and the ecology and evolution of Arctic vertebrates.
2012
25 pages; International audience; Climate change is taking place more rapidly and severely in the Arctic than anywhere on the globe, exposing Arctic vertebrates to a host of impacts. Changes in the cryosphere dominate the physical changes that already affect these animals, but increasing air temperatures, changes in precipitation, and ocean acidification will also affect Arctic ecosystems in the future. Adaptation via natural selection is problematic in such a rapidly changing environment. Adjustment via phenotypic plasticity is therefore likely to dominate Arctic vertebrate responses in the short term, and many such adjustments have already been documented. Changes in phenology and range w…
Czy gęsi są głupie? O ptasiej filozofii Mikołaja Reja słów kilka
2017
The article is an attempt to solve the enigma on the potential advantages of the Polish language that comes from the line to the person who will read from Zwierzyniec Mikołaj Rej. The author reviews the most famous and popular meanings of the symbols geese from antiquity to the Renaissance times. Indicated is a long road traveled by this positively associated theme until symbol geese has become synonymous mindless chatter. The opposite of the “idle talk” is the work of Miko³aj Rej, who was the father of Polish literature, hoisted our national culture to new heights.
Forebrain specialization and the olfactory system in anseriform birds. An architectonic and tracing study.
1992
In anseriform birds the mediodorsal part of the rostral forebrain is covered by a corticoid (= layered) structure, establishing a unique feature of this avian group since in other birds the non-cortical accessory or dorsal hyperstriatum occupies the corresponding surface area of the hemisphere. The efferents of the olfactory bulb are shown to reach this region, which thus can be identified as a heavily enlarged retrobulbar area. The large expansion of this olfactory representation may indicate an important biological function. In comparison to the mammalian olfactory system the three stratified olfactory projection centers of birds should be regarded as retrobulbar, prepiriform and periamyg…
Molecular characterisation, evolution and expression analysis of g-type lysozymes in Ciona intestinalis
2017
Lysozyme is an important defense molecule of the innate immune system. Known for its bactericidal properties, lysozyme catalyzes the hydrolysis of b-(1,4)-glycosidic bonds between the N-acetyl glucosamine and N-acetyl muramic acid in the peptidoglycan layer of bacterial cell walls. In this study, the complete coding sequence of four g-type lysozymes were identified in Ciona intestinalis. Phylogenetic analysis and modelling supported the hypothesis of a close relationship with the vertebrate g-type lysozymes suggesting that the C. intestinalis g-type lysozyme genes (CiLys-g1, Cilys-g2, CiLys-g3, CiLys-g4) share a common ancestor in the chordate lineage. Protein motif searches indicated that …
Study of the flying geese theory from a political point of view : a Japanese propaganda argument in the post world war II era
2009
The Flying Geese Theory (gankoo keitai hattenron 雁行形態発展論), dating from 1932, is one of the rare cases of a scientific theory that was used as a part of Japanese wartime propaganda, and which also survived and succeeded in the postwar era. It was used to legitimize the 'New Order in East Asia (TōA shinchitsujo 東亜新秩序) in 1938, and the new formulation of the 'Greater East Asia Co-Prosperity Sphere‘ (Dai TōA kyōeiken大東亜共栄圏) in 1940. Later in the 1980s the Flying Geese Theory/Pattern became the most successful candidate for explaining the expansion of ‗Asian economical miracles‘ in the postwar era. This study focuses on this famous piece of economical and political rhetoric. The intention is to …
