Two islands lie off the coast of Florida. One is larger and the other is closer to the mainland. What determines which one will have more species?

Based on the traits in the table below, which of the following would be the most parsimonious arrangement of species on the tree below? List species from top to bottom, following the arrow on the right.

You arrive on an alien planet and settle down to live there for a long time.  There are very few species.  Two of the species (A and B) are sometimes common and sometimes rare.  When you start keeping track of population changes you discover that the population sizes fluctuate on a regular cycle in close synchrony.  Species B always increases first, followed by species A. Which of the following would be the best explanation for what you are seeing? Group of answer choices -Species A is a predator and there is a time lag between changes in the density of its prey and species A's population change -Species A is a predator and it can respond instantly to changes in its prey population -Species B is a predator and there is a time lag between changes in the density of its prey and species B's population change -Species B is a predator and it can respond instantly to changes in its prey population

Two dosely related Aster species occupy two different habitats. The first one (Aster 1) lives in a temperate forest understory that experiences few disturbances but intense competition for light. The second (Aster 2) Ilives in a prairie environment that experiences frequent disturbances such as fires, grazing, and droughts. Which species do you expect to have larger seeds? Which species do you expect to produce more seeds? ) Aster 1 has larger and more seeds than Aster 2 Aster 2 has larger and more seeds than Aster 1 Aster 1 has smaller and more seeds than Aster 2 Aster 2 has smaller and more seeds than Aster 1 Aster 1 has smaller and fewer seeds than Aster 2 Aster 2 has smaller and fever seeds than Aster1

(b) Flat-podded golden rain tree introduced to central Florida 9.0 8.5 during this time 8.0 7.5 7.0 6.5 6.0 5.5 1880 1900 1920 1940 1960 1980 Date 88. The above graph shows the length of soapberry (an insect) beaks over time. Before the Flat-podded golden rain tree was introduced, beak size varied between short and long. After the tree was introduced, beak length became a. Shorter; disruptive b. Longer; disruptive c. Shorter; directional d. Longer; directional This example illustrates selection. Beak length (mm)

Two islands in the Pacific Ocean are of equal size but differ in their distance from the mainland. Island C is 5 km from the mainland, while Island D is 50 km away. According to island biogeography theory, how would the extinction rates on these islands compare and why? Group of answer choices: A. Island D would have higher extinction rates because its greater distance from the mainland makes it harder for species to recolonize after local extinctions, reducing species turnover B. Both islands would have similar extinction rates because island size, not distance from the mainland, primarily determines extinction rates C. Island C would have lower extinction rates due to its smaller distance from the mainland, allowing easier recolonization and rescue effects D. Island C would have higher extinction rates due to its proximity to the mainland, which increases competition and predator pressure from mainland species

Based on the interaction between species A and species B in the previous question, choose the most likely combination of alpha and beta coefficients.a. alpha = 1, beta = 10b. alpha = 10, beta = 1c. alpha = 1, beta = 1d. alpha = 0, beta = 1Previous questionTwo species of aquatic snails live in a nearby creek. Species A is a very strong competitor of Species B, who is a weak competitor. What do you expect will happen to the realized niche of Species B if both species share the same fundamental niche? IT decreases

slands are well known for having many endemic (unique) species. What is a likely explanation for this pattern?   A. Humans bring partly or fully domesticated species with them when they arrive on islands.   B. Colonizers encounter fewer competitors on an island, so they can diversify.   C. Islands are more complex habitats than continents are, so they have more niches for specializations.   D. Colonizers are likely to have more diversity than local populations and thus outcompete them.   E. The type of organism that is a good colonizer has more than the average amount of genetic variability, so it's more likely to speciate.

The yellow-legged gull (Larus michahellis) is a widespread species along the Atlantic coasts of France and the Iberian Peninsula, the Azores Islands, Madeira, the countries of the Mediterranean basin and the Black Sea. It was formerly considered as a subspecies of Herring Gull (L. argentatus), with which it coexists in some reproductive areas. Only recently L. michahellis has been recognized as a distinct species. Following detailed comparison of the two species, researchers found that the L. michahellis's restricted but dense head-streaking and advanced primary molt in late summer, are not compatible with L. argentatus. Larus michahellis has a proportionately longer, heavier bill and bulkier head and body than L. urgentutus. In addition, L. michahellis's yellow bill has a red gonydeal spot, both colors typically brighter than in L. urgentutus outside breeding season. They also have an orange-red to vermilion orbital ring and yellow legs. DNA research, however, suggests that the…

Say you found another isolated pond about a mile from your first pond.  This second isolated pond contains a population of 50,000 Danio kerri. You take a female fish from pond #1 and a male fish from pond #2.  They look the same; they mate and produce fertile offspring.  This suggests that these fish are members of  _______ based on the ______. Group of answer choices the same species; biological species concept AND morphological species concept the same species; biological species concept (only) different species; morphological species concept AND biological species concept the same species; morphological species concept (only) different species; morphological species concept (only)
