What is ecology?
As a discipline, paleoecology interacts with, depends on and informs a variety of fields including paleontology , ecology , climatology and biology. Paleoecology emerged from the field of paleontology in the s, though paleontologists have conducted paleoecological studies since the creation of paleontology in the s and s. Combining the investigative approach of searching for fossils with the theoretical approach of Charles Darwin and Alexander von Humboldt , paleoecology began as paleontologists began examining both the ancient organisms they discovered and the reconstructed environments in which they lived.
Visual depictions of past marine and terrestrial communities has been considered an early form of paleoecology. While the functions and relationships of fossil organisms may not be observed directly as in ecology , scientists can describe and analyze both individuals and communities over time. To do so, paleoecologists make the following assumptions:.
The tool most often used, due to its consistency and preciseness, when dealing with very old samples, is Uranium—Lead dating. It was first used in but via.

No bigger than a minnow, the three-spine stickleback may seem a puny player in the underwater world. But along the European coastline of the Baltic Sea, it has edged out its own predators—toothy pike and perch, fish that grow longer than your forearm.
Records dating back 40 years show how the flamboyant little stickleback has shifted the ecosystem, thwarting efforts to restore the larger species favored by human fishers. Ecologists say what has happened in the Baltic is a dramatic example of a predator-prey reversal, in which two species trade places on the food chain, drastically altering the rest of the ecosystem. To find out what was going on, the researchers unearthed 13, surveys of fish done between and by scientists and fisheries managers along kilometers of the western coast of the Baltic Sea.
Those fish prevailed in the fresher waters 8 kilometers closer to shore. But in the s, sticklebacks began to outnumber their predators closer to land, their dominance spreading toward more protected bays and inland waters. Instead, complex ecological factors appear to have first worked against pike and perch: Beginning in the s, gray seals became more common, thanks to better water quality and an end to bounty hunting. The seals, along with cormorants, began to eat more pike and perch.

Disease Ecologist Dr. Peter Daszak Featured on. They are all linked to human, anthropogenic, environmental changes. They emerge through the connections we make to nature. These will happen unless we change our relationship with nature. Biodiversity experts, like disease ecologist Dr. Last year, IPBES alerted the world to the fact that 1 million species of plants and animals now risk extinction.
Over the course of six widely varied episodes, leaders from the frontlines of biodiversity research and action, speaking in their individual expert capacities, will share cutting-edge science and vibrant personal insights about some of the most important issues facing people and the planet — starting with the links between COVID, nature loss and what we can do to reduce the risk of future pandemics. Daszak, emphasizing the importance of preventive measures that can protect the health of people and the rest of nature as well.

Biologists awaken dormant eggs to observe life from the past and tease out how it differs from what lives today. DOI: Scientists always seek new peepholes into the past. Astronomers chase light, the more dated and distant the better. Geologists hunt for ever-older rock. Calling themselves resurrection ecologists, many revive so-called resting eggs, some a century old, produced by small aquatic organisms.
Once hatched, these organic time capsules produce living examples of what a species used to be like, allowing ready comparisons to what exists today. Above are zooplankton, in various developmental stages, that originated as diapausing eggs.

The Sonic Research Studio was established in the late s at Simon Fraser University by Canadian composer and foundational sound studies researcher R. Schafer, to pursue soundscape research through the World Soundscape Project. In the s the studio and the WSP were home to several notable and longstanding researchers in acoustic ecology, including Barry Truax, a professor now Emeritus and electroacoustic composer based at Simon Fraser University; Hildegard Westerkamp, a freelance acoustic ecology thinker, activist, and soundscape composer; and David Murphy, a senior lecturer in video and sound in the School of Communication.
With Barry Truax’s recent retirement in , and the creation of the Glenfraser Endowed Professorship in Sound Studies, this teaching space is now shared between Dr. The studio contains a wealth of archival materials in soundscape studies and acoustic ecology, as well as cutting edge research in listening pedagogies, soundscape composition, sonification for social change, and various cultural studies of sound.

Coral is a useful tool for scientists who want to understand changes in past climate, but recalling that history presents its own set of challenges. In order to know anything about past climate from corals, we need to know their age. This decay occurs when an unstable form of the element, known as an isotope, changes into a stable one by ejecting a part of its nucleus. As 14C decays, the ratio of 14C to 12C in a sample changes over time.
This change allows us to measure age. The difference between the two is the age since it was formed.

We are seeking community-based, afterschool program providers with a core constituency of underrepresented youth, primarily females, ages If your organization is interested, please contact us! Careers in ecology involve the scientific study of the interactions of organisms with each other and their environment often with a specific focus on processes that control how abundant specific organisms are and how they are distributed. Ecologists focus on the connections between living organisms and how those connections are influenced by the environment, so much of the work that ecologists do take them out in the field.
Behavioral ecologists observe and document behaviors, by humans or other species, in response to a given environmental stimulus. From mating to feeding to social interactions, behavioral ecologists identify the environmental pressures that shape those behaviors! These STEM professionals are keen observers and historians that like to crunch the numbers to determine how evolutionary development impacts behavior. Trees carry the history of a location in their rings and dendrochronologists are skilled at deciphering that history.
The tools of dendrochronology are used to pinpoint timing of major events and measure rates of change both in the environment and in works of art and architectural pieces made of wood. It is also used in radiocarbon dating to validate radiocarbon aging for things not made from trees. Ecologists study just that, the ecology, of a given area. This involves understanding the interactions between the living and nonliving components of said area. Our ecologist is involved in the conservation and restoration of the Everglades in south Florida.
Ecologists have a deep interest, if not love, of nature and all of the factors involved in preserving nature.

One of the biggest, but rarely talked about threats to prairie conservation comes during transitions of land ownership. I think about the same issue with my own family prairie, though I hope I have many decades before the issue becomes urgent. Conservation easements are a tool that can provide some help, and they are absolutely valuable in landscapes where prairies are rapidly being turned into crop land. A landowner might agree, for example, not to ever construct a building on the site, till the land for crops, or do other things that would destroy the prairie or threaten the conservation value of the property.
That agreement becomes legally binding and is attached to the deed so that all future landowners have to abide by the same restrictions for the length of the easement, which is often perpetual. Typically, those restrictions are difficult, if not impossible, to alter once everything has been signed.
