List three factors that are contributing to the decline of pollinator populations
Step by step
Solved in 3 steps
- In response to warmer spring temperatures, a plant species is flowering earlier in the year than it would have historically. However, its primary pollinator, the bumblebee, has not been as responsive to temperature changes and continues to emerge at the same time as usual. As a result, peak floral displays have finished prior to pollinator emergence. This change in plant-pollinator interactions is an example of: a.Uncoupling of interdependent species b.Sympatric speciation c.Heterochrony d.Interspecific evolutionWhat are three aspects of your lifestyle that might directly or indirectly contribute to declines in European honeybee populations and the endangerment of other pollinator species (Core Case Study)?What are three aspects of your lifestyle that mightdirectly or indirectly contribute to decline in European honeybee populations and the endangerment ofother pollinator species?

What roles do competitive exclusion and character displacement play in community structure?If some individual plants of a species consistently attracted one type of pollinator, while other individual plants of that same species consistently attracted a different type of pollinator, what could be the possible consequence?
- determine how to deal with the invasive species that are listed here, or determine if a species is actually beneficial to the community they've been introduced to. the honeybee is naturally from europe, and was introduced to north america in the 1700s. in the modern united states honeybees are major pollinators. this species hasn't outcompeted other north american species like the bumblebee. do you choose to try to control this species, or not?the africanized honeybee better known as the "killer bee" escaped a facility in brazil. the killer bee's population has exploded, but this subspecies has not directly impacted other bee species. the well known aggressiveness of the hives has caused consistent problems over the past few decades for humans in several conditions. do you choose to try to control this species, or not? burmese python.jpg the burmese python can grow to be large constrictor capable of reaching 23 ft. in some cases. these snakes were illegally kept as pets, and released…What are 4 mutualistic and 4 antagonistic interaction between two or more species that are exploited to improve agricultural production or food productionDescribe TWO ways in which fire ants either positively or negatively affect ecosystem services related to agriculture.
- For the article "Effects of an invasive predator cascade to plants via mutualism disruption" (https://www.nature.com/articles/ncomms14557) answer the following points: - Summarize the results - What did the author(s) conclude about the question or pattern based on the data? - What are the strengths/weaknesses of the study? What might you do as a follow-up?Plants vary widely in how they allocate biomass to roots, leaves and stems. Two key measures of plant allocation in an ecosystem context are leaf area index (LAI) and the root to shoot ratio. a) Define each of these measures and discuss how variation in each measure can influence net primary production (NPP). b) Pick one of the measures and discuss how and why you would expect it to vary in relation to an abiotic factor of your choice. Underline the abiotic factor you choose.what are 4 antagonistic interaction between two or more species that are exploited to improve agricultural production or food production
