My purple pen is out of ink
Answer/Explanation:
The two correctly cited sourxes are:
1. Bravo, Susana. "Amazonian Black Howler Monkeys: Seed Dispersers or Pests?" Biotropica, vol. 40, no. 8 (2008), pp. 71–76.; and
2. Martins, Marcel. "Pollination and Pollinators of the Amazonian Forests." Global Rainforests, vol. 19, no. 5 (2015), pp. 17–28.
These two are correct because they contain the title of the work, the title of the journal, it's volume, year of publication and the page where the work is located in the journal.
