The energy transition is a challenge and an urgency for the world facing the scarcity of fossil fuels and their impacts in the ecosystems by climate change. Through this study, we wanted to assess the potential of new and renewable energies in the Republic of Mali and Azerbaijan in view of their promotion for the preservation of forest areas, in a world facing the challenges of global warming. The methodology was based on documentary collection and documentary exploitation and analysis of cartographic data, tables and other figures. The study revealed to us the high frequency of the potential of these so-called energies, especially solar in Mali and hydraulic, wind and solar in Azerbaijan and the commitment of the authorities of these States to promote the energy transition but also the dependence of these States on fossils such as: oil and gas. The Republic of Azerbaijan exports fossil fuels and Mali depends on imports. The transition to alternative energy resources will undeniably make it possible to reduce greenhouse gas emissions at the global level and to preserve forest ecosystems in both countries.

Gentle blood sampling from tortoises (Testudines) to detect blood parasites
Статья научная
Blood can be drawn from the jugular, brachial, femoral, ventral and dorsal coccygeal veins, occipital venous sinus, and heart from most species of tortoises and aquatic turtles. An alternative method for obtaining high-quality blood samples from tortoises of the genus Testudo for the detection of blood parasites by blood extraction using a medicinal leech ( Hirudo medicinalis ) has been proposed. One or two leeches were placed on each individual, depending on the body weight of the turtle. The time spent by leeches on blood sucking took from 20 minutes to 1 hour (average 35 minutes). After the pumped leeches fell off, they were immediately placed in sterile double-dish, where they contacted with a cotton swab moistened with ethyl alcohol in order to cause regurgitation of the sucked blood. In a comparative study of microscopic specimens prepared from blood samples of the spur-thighed tortoise obtained by two methods of exsanguination: cardiopuncture and medical leeches, no qualitative differences were found. In all specimens, blood cells and intraerythrocytic stages of blood parasites were equally suitable for identification. This method of exsanguination is also effective, as well as traditional methods of blood sampling from turtles, but in contrast to them, it is simple to perform, more humane and safer for these animals.
