What Is The Potential Threat Of Environmental Change To The Island Communities Of The Pacific? Introduction. The Pacific Islands are facing devastating impacts of climate change including increasing droughts and water scarcity, coastal flooding and erosion, changes in rainfall that affect ecosystems and food production, and adverse impacts to human health (IPCC, 2014, 2018). What
Why Do Islands Have More Specialist Species? Many island species have evolved to be specialists versus generalists because of the limited resources, such as food and territory, on most islands. The long-term survival of specialists may be jeopardized if and when invasive species, typically generalists, are introduced and outcompete the specialists. Why are most island
Why Are The Islands Key In The Study Of Evolutionary Biology? Volcanic islands are particularly good laboratories for evolutionary science because they can be dated accurately using radioactive isotope decay and because they start out as lifeless masses of rock emerging from the sea. Why should islands study evolution? In some ways, islands provide a
What Type Of Species Are More Susceptible To Extinction? Large animals, by virtue of their low population densities, are at increased risk of extinction. Moreover, an animal species that produces few offspring each year and that suffers a major loss in numbers from human activity will need more time to recover than a species with
For Which Of The Following Reasons Do Small Isolated Islands Have A Greater? For which of the following reasons do small isolated islands have a greater rate of species extinction than larger, less isolated islands? Small isolated islands are more likely to receive more migrating species. Small isolated islands provide opportunities for a greater diversity
