Which of the following is included in the definition of species
Biological Species (most common), ecological, and evolutionary species concept.
“Ontogeny recapitulates phylogeny”
it is Ernst Haeckel’s theory that attempts to explain similarities between humans and other animals. Suggests all vertebrate embryos develop in a similar way and points to common origin in evolutionary line.
The species concept that species are reproductively isolates is known as
Biological species (groups of interbreeding natural populations)
A mule is not a true species because
mules are sterile and cannot reproduce
Where is adaptive radiation most commonly found?
in remote and isolated areas
Darwin’s finches are an example of what type of speciation?
allopatric speciation: species forming through geographical separation
Which of the following would be an example of adaptive radiation?
silverswords, lobelioids, honeycreepers, land snails
species forming at the same place and time
Why are invasive species successful in new environments?
they are free of predators, competitors, diseases and parasites that limit their populations in natural habitat, exploits resources
What is a naturalization plant?
an established self-perpetuating plant, widespread dispersal & incorporation into native flora/ecosystem
Why is Hawaii particularly at risk from biological invaders?
Honolulu is an international port. Lots of tourists, trade, and imported goods.
What is the most common way alien plants are introduced to Hawaii today?
Ornamental plant trade (70% of Hawaii’s alien plants)
What is a biological invader?
An invasive or alien species that may cause environmental harm when they establish a new home, reproduce, and spread in their new home.
What is a consequence of invasive species on native plant species?
it alters important nutrient cycling, affects hydrology (water flow), disrupts the ecosystem processes and competes with the natives
How are ocean’s impacted by invasive species?
because of ocean-going vessels & commercial fishers, it changes the biodiversity & distribution of marine organisms along coastlines, algae overgrowth on coral
What are the characteristics of invasive plants?
propagules (seeds&spores) dispersed by wind, animals, water. High reproduction, rapid growth rate, significant defense mechanism, quick maturation
Biodiversity is defined as?
number & variety of organisms found w/in an area
75% of Hawaii’s flowering plant species arrived by?
