Presentation on theme: "Chapter 4! Evolution, Biological Communities, and Species Interactions"— Presentation transcript: 1 Chapter 4! Evolution, Biological

Because interspecies interactions are the key to understanding biological communities, it is important to know how species interactions arise and evolve. Here

Feb 9, 2010 Biologists have known for long that ecology, the interaction between One stream community had a diverse group of fish species, some of which were funded by the Frontiers in Integrative Biological Research initiativ Species interactions govern evolutionary and ecological effects of population Species interactions therefore influence the effect of harvesting on community Affiliation: Department of Biology, University of York, York, United Kingdom --- The av A Gårdmark · 2005 — Species interactions therefore influence the effect of harvesting on community structure and dynamics as well as on trait evolution. Yet, this problem has often Mark McPeek synthesizes the ecological and evolutionary dynamics generated by species interactions that structure local biological communities and regional We use different species of freshwater organisms to study both the bottom-up on their resources, which can mediate species interactions locally and across The Department of Ecology and Genetics is a part of the Evolutionary Biology av J Årevall · 2020 — Department of Physics, Chemistry and Biology.

4.3 Summarize how community properties affect species and populations.

Two finch species have similar beaks when they occur separately (on the islands of Daphne and Los Hermanos), but beak sizes shift when the species occur

Answer. Stronger species interactions, however, can alter evolutionary outcomes and either dampen or promote evolution of constituent species depending on the number of species and the distribution of interaction strengths across the interaction network. Genetic interactions, such as horizontal gene transfer, might also affect evolutionary outcomes.

- a community begins to develop on an unoccupied site - occur after disturbances have been harsh enough to wipe out previous species - role: give nutrients in the soil ex: A lava flow creates a new land area that Is colonized. - - the first colonists are termed PIONEER SPECIES

Nonrandom species distribution, caused by probabilistic events of migration and speciation, create nonrandom Critical Environmental Factors

For many species, the interaction of several factors, rather than a single limiting factor, determines biogeographical distribution.

Altitude = oxygen, temperature, food

May be a specific critical factor that mostly determines abundance and distribution. Quiz 3: Evolution, Species Interactions, and Biological Communities. _________ habitat specialist found exclusively in one specific type of habitat.

species:mosses • Species can facilitate/or inhibit the entry of other species into the community • Can reach a climax community CHAPTER 4 Evolution, Biological Communities, and Species Interactions 75 Case Study attributes are more likely to live and reproduce than those less well-endowed. Because the more fit individuals are especially successful in passing along their favorable traits to their offspring, the whole population will gradually change to be better suited Evolution, Biological.

CHAPTER 4 The relatively young and barren volcanic islands of the Case Study: Darwin’s Voyage of Discovery 4.1 Evolution Produces Species Diversity Natural selection leads to evolution All species live within limits The ecological niche is a species’ role and environment Speciation maintains species diversity Evolution is still at work Exploring Science: New Flu Vaccines Taxonomy describes relationships among species 4.2 Species Interactions Shape Conversely, understanding the ecology of communities of species requires appreciation of evolution and the role of history. Darwin, whom many view as a founder of ecology, appreciated that “plants and animals, most remote in the scale of nature, are bound together by a web of complex relations” (ref. 1 , p. 61).

Interactions may show selection mosaics, such that different traits and outcomes are favored by natural selection in different communities. Biological Communities and Species Interactions.

Hutchinson would later observe, “every species exists within a range of physical and chemical conditions (temperature, light levels, acidity, humidity, salinity, etc.) and also biological interactions (predators and prey present, defenses, nutritional resources available, etc.)” (Cunningham 2012).
