In 941, Igor led another major Rus' attack on Constantinople, probably over trading rights again. A navy of 10,000 vessels, including Pecheneg allies, landed on the Bithynian coast and devastated the Asiatic shore of the Bosphorus. The attack was well-timed, perhaps due to intelligence, as the Byzantine fleet was occupied with the Arabs in the Mediterranean, and the bulk of its army was stationed in the east. The Rus’ burned towns, churches, and monasteries, butchering the people and amassing booty. The emperor arranged for a small group of retired ships to be outfitted with Greek fire throwers and sent them out to meet the Rus’, luring them into surrounding the contingent before unleashing the Greek fire. Liutprand of Cremona wrote that "the Rus', seeing the flames, jumped overboard, preferring water to fire. Some sank, weighed down by the weight of their breastplates and helmets; others caught fire." Those captured were beheaded. The ploy dispelled the Rus’ fleet, but their attacks continued into the hinterland as far as Nicomedia, with many atrocities reported as victims were crucified and set up for use as targets. At last a Byzantine army arrived from the Balkans to drive the Rus' back, and a naval contingent reportedly destroyed much of the Rus' fleet on its return voyage (possibly an exaggeration since the Rus' soon mounted another attack). The outcome indicates increased military might by Byzantium since 911, suggesting a shift in the balance of power.
What did the emperor of Byzatine do to some of the old retired ships to help fight the Rus?

Having small population size is a characteristic almost universally inherent to apex predators, humans and dogs by far the most blatant exceptions. Low numbers wouldn't be a problem for apex predators if there was an abundance of prey and no competition or niche overlap, a scenario that is rarely, if ever, encountered in the wild. The competitive exclusion principle states that if two species' ecological niches overlap, there is a very high likelihood of competition as both species are in direct competition for the same resources. This factor alone could lead to the extirpation of one or both species, but is compounded by the added factor of prey abundance.
What two apex predators do not have a small population size?
A: humans and dogs

Much of El Salvador was home to the Pipil, the Lenca, Xinca, and Kakawira. The Pipil lived in western El Salvador, spoke Nawat, and had many settlements there, most noticeably Cuzcatlan. The Pipil had no precious mineral resources, but they did have rich and fertile land that was good for farming. The Spaniards were disappointed not to find gold or jewels in El Salvador as they had in other lands like Guatemala or Mexico, but upon learning of the fertile land in El Salvador, they attempted to conquer it. Noted Meso-American indigenous warriors to rise militarily against the Spanish included Princes Atonal and Atlacatl of the Pipil people in central El Salvador and Princess Antu Silan Ulap of the Lenca people in eastern El Salvador, who saw the Spanish not as gods but as barbaric invaders. After fierce battles, the Pipil successfully fought off the Spanish army led by Pedro de Alvarado along with their Mexican Indian allies (the Tlaxcalas), sending them back to Guatemala. After many other attacks with an army reinforced with Guatemalan Indian allies, the Spanish were able to conquer Cuzcatlan. After further attacks, the Spanish also conquered the Lenca people. Eventually, the Spaniards intermarried with Pipil and Lenca women, resulting in the Mestizo population which would become the majority of the Salvadoran people. Today many Pipil and other indigenous populations live in the many small towns of El Salvador like Izalco, Panchimalco, Sacacoyo, and Nahuizalco.
El Salvador was home to which indigenous peoples?
A:

assistant: the Pipil, the Lenca, Xinca, and Kakawira
