What are the four major factors that affect species richness?
Many factors affect small-scale species richness, including geographic (e.g. species pool, dispersal), biotic (e.g. competition, predation, facilitation) and abiotic (e.g. resource availability, environmental heterogeneity, disturbance frequency and intensity).
What environmental factors might affect the species richness of these plants?
The factors related to these patterns of small- scale species richness include (1) geographic factors such as scale of observation, available species pool and dispersal patterns, (2) biotic factors such as competition or predation and (3) abiotic environmental factors such as site resource availability, disturbance and …
How does climate affect species richness?
Climate change can affect species in myriad ways including the expansion, contraction, and “migration” of habitat; increased incidence of disease and invasive species; changes in temperature, precipitation, and other environmental conditions; shifts in food availability; and failure of ecological relationships with …
Are there any environmental factors that could impact species diversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.
What factors can affect species richness?
Several factors affect small-scale species richness, including geographic factors such as the regional species pool, dispersal distance and ease of dispersal, biological factors such as competition, facilitation, and predation as well as environmental factors such as resource availability, environmental heterogeneity …
What affects species richness on islands?
Species richness on oceanic islands has been related to a series of ecological factors including island size and isolation (i.e. the Equilibrium Model of Island Biogeography, EMIB), habitat diversity, climate (i.e., temperature and precipitation) and more recently island ontogeny (i.e. the General Dynamic Model of …
What are the two main factors influencing species richness on an island quizlet?
Two main factors influencing species richness on an island? You just studied 149 terms!
- the number of species decrease with increasing distance from the source pool.
- the number of species is directly proportional to island size.
- species turnover is high.
What factors affect the types and abundances of species in a community?
Community structure is influenced by many factors, including abiotic factors, species interactions, level of disturbance, and chance events. Some species, such as foundation species and keystone species, play particularly important roles in determining their communities’ structure.
How does temperature affect the environment?
Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier.
What factors affect biodiversity and the relationships between species and the physical environment?
Several factors contribute to species diversity, including habitat diversity, competition among species, and genetic diversity. Genetic diversity within a species not only is necessary to maintain diversity among species,6 but also contributes to the diversity of food, fiber, and medicines available from nature.
