Les Phocéens, Marseille et la Gaule (viie-iiie s. av. J.-C.)
Last of the expeditions of the Greek archaic colonization, the Phocean colonization in the western Mediterranean assumes a particular dimension owing to a real convergence between the strength of the metropolis’ maritime activity, the context of ...

Hemotropic mycoplasmas in little brown bats (Myotis lucifugus). [PDF]
BackgroundHemotropic mycoplasmas are epicellular erythrocytic bacteria that can cause infectious anemia in some mammalian species. Worldwide, hemotropic mycoplasmas are emerging or re-emerging zoonotic pathogens potentially causing serious and ...

DR. ROMANES, in criticising a book (“Zoological Sketches”), in NATURE, vol. xxvii. p. 333, says: “The writer speaks of vampire bats as those which suck the blood of sleeping persons, whereas the truth is, as Belt has remarked, ‘the vampire is the most harmless of bats.’”

Antioxidant Defenses in the Brains of Bats during Hibernation. [PDF]
Hibernation is a strategy used by some mammals to survive a cold winter. Small hibernating mammals, such as squirrels and hamsters, use species- and tissue-specific antioxidant defenses to cope with oxidative insults during hibernation.

Background Fruit bats play an important role in pollination and seed dispersal, and their conservation is important to maintain the productivity of some crops and natural ecosystems. The objective of this study was to investigate the knowledge, attitudes,

Bats have a very long evolutionary history and are highly differentiated in their physiological functions. Results of recent studies suggest effects of some host factors (e.g., phylogeny and dietary habit) on their gut microbiota.

Sonochemically‐Induced Reduction of Alkenes to Alkanes with Ammonia
Ammonia is used as a hydrogen source for the reduction of alkenes to alkanes. The originality stems from the use of cavitation bubbles that act as “microreactors” to break the N−H bond of NH3. As a result, this protocol does not involve any catalyst and it releases nitrogen (and partly hydrogen) as a sole co‐product.

The distribution of bat species across the underground sites of Georgia [PDF]
In Georgia, investigations of bat species using caves have been conducted since the beginning of the 20th century. However, robust knowledge is still largely unavailable, as only about 15% of the roughly 2,000 underground sites have been surveyed for ...

New directional bat algorithm for continuous optimization problems [PDF]
Bat algorithm (BA) is a recent optimization algorithm based on swarm intelligence and inspiration from the echolocation behavior of bats. One of the issues in the standard bat algorithm is the premature convergence that can occur due to the low exploration ability of the algorithm under some conditions.
