Predators, prey, and natural disasters attract ecologists
Science (New York, N.Y.)
|August 27, 1993
Summary
Ecologists gathered to discuss river ecology, predator-prey dynamics, evolutionary parasitology, and soil impacts from clearcutting. The 78th Ecological Society of America meeting highlighted key research areas in environmental science.
Area of Science:
- Ecology
- Environmental Science
- Evolutionary Biology
Background:
- The Ecological Society of America (ESA) convenes annually to present cutting-edge ecological research.
- The 78th annual meeting was held in Madison, Wisconsin, from July 31 to August 4.
Purpose of the Study:
- To summarize key research presented at the 78th ESA annual meeting.
- To highlight diverse ecological topics including river systems, species interactions, and ecosystem impacts.
Main Methods:
- Presentations and reports from leading ecologists.
- Discussions on various ecological research areas.
Main Results:
- Reports covered the ecological effects of dams and levees on large rivers.
- Research explored predator-prey interactions and the role of parasites in evolution.
- The impact of clearcutting on soil organisms was also a significant topic.
Conclusions:
- The meeting showcased a broad spectrum of current ecological research and challenges.
- Key areas of focus included aquatic ecology, evolutionary dynamics, and soil science.

02:39Predator-Prey Interactions
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.Although predation is commonly associated with carnivory, for...
02:26Ecological Disturbance
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...
01:50Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
01:57What is Conservation Biology?
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.
01:32What is Natural Selection?
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.The Theory of Natural...
02:02Ecological Niches
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.Multiple species cannot occupy the exact same niche within their habitat. If the niches of two or more species overlap to a large extent, the competitive exclusion principle dictates that one species will outcompete the other, forcing it to...
