Swamp buffalo and river buffalo do not interbreed easily, but fertile offspring can occur. The rumen contains a larger population of bacteria, mainly cellulolytic, lower protozoa and higher fungal zoospores. Nitrogen ammonia and high pH.

Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry. Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world. The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley. Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 k...

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...
