Here is a question about this article: Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.
What is the answer to this question: What species struggle to with the introduction of new species?
****
So... endemic and other local species

Here is a question about this article: Economic and political migrations made an impact across the empire. For example, the Russian and Austria-Habsburg annexation of the Crimean and Balkan regions respectively saw large influxes of Muslim refugees 200,000 Crimean Tartars fleeing to Dobruja. Between 1783 and 1913, approximately 57 million refugees flooded into the Ottoman Empire, at least 3.8 million of whom were from Russia. Some migrations left indelible marks such as political tension between parts of the empire (e.g. Turkey and Bulgaria) whereas centrifugal effects were noticed in other territories, simpler demographics emerging from diverse populations. Economies were also impacted with the loss of artisans, merchants, manufacturers and agriculturists. Since the 19th century, a large proportion of Muslim peoples from the Balkans emigrated to present-day Turkey. These people are called Muhacir. By the time the Ottoman Empire came to an end in 1922, half of the urban population of Turkey was descended from Muslim refugees from Russia.
What is the answer to this question: The annexation of what two regions resulted in large groups of Muslim refugees coming into the empire?
