Ecología Biodiversidad II: Cambio de hábitos y hábitats por Devin Reese, PhD. Lectura Prueba Teach with this In the Ehrlichs' "rivet popper" hypothesis, the "rivets" are ______. individual organisms species ecosystems extinctions There are many secluded places on Earth that are still like they were before humans. true false Why should everyone care about impacting other species? They deserve a helping hand. They were on Earth before us. They play vital roles in ecosystem function. There are certain species that are valuable. What is the best description of habitat fragmentation? Fragmentation splits up habitats into smaller patches that may eliminate some species that need more space. Fragmentation alters the home range sizes of animals so that they start invading spaces belonging to humans. Fragmentation upsets the natural balance of human habitats and habitats for other species, causing more overlap. Fragmentation converts habitats to parking lots, roads, and buildings that are not suitable habitat for some species. Humans have caused the first major global changes on Earth. true false Which statement best captures the outcomes of global changes, such as to climate? Global changes have negative impacts on all species and therefore reduce biodiversity. Global changes have positive impacts on all species and therefore increase biodiversity. Global changes may benefit some species, but are likely to reduce biodiversity in the long run. Global changes may harm some species, but are likely to increase biodiversity in the long run. There are multiple ways that species respond to changes in global climate. true false Which is the best byline to define the Anthropocene? The Age of Humans The Age of Extinctions The Age of Habitat Conversions The Age of Global Climate Changes Environmental stewardship is largely the responsibility of ______ and ______. Environmental policy-makers and other authorities Citizens of the Earth and environmental decision-makers Indigenous tribes and other people living near natural areas Wildlife biologists and people interested in nature Resultados de Prueba
