List of top Applied Ecology & Evolution Questions on Conservation of Biodiversity

Which one of the following is an invasive plant species in India?
Which one or more of the following phenomena make(s) small populations vulnerable to extinction?
The phylogeny of six species of birds (Species 1 to Species 6) is illustrated below, drawn so that horizontal branch lengths correspond to genetic distance between the species. These six species are distributed across three islands: Island X harbours Species 1, 4, and 6; Island Y harbours Species 1, 2, and 4; and Island Z harbours Species 3, 4, and 5.

Which one of the following is true about the phylogenetic diversity of these islands?

Which one (or more) of the following conservation actions would NOT benefit native species?

Hunting is a major source of mortality for large frugivorous birds. These birds disperse the seeds of forest trees and are the primary contributors to forest regeneration. The graphs show the distribution of different age-classes of a frugivore-dispersed tree species at two isolated sites.
