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. But in ecological studies, scientists hatch them and extract their DNA for research.

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.

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. Easements can help eliminate some clear threats to prairies such as housing development or tillage, but easements are not well-designed to ensure that current or future landowners control invasive plants or otherwise manage the site to benefit plant diversity or habitat quality.

Challenges to prairies change over time, as do our best ideas about how to address them. Easements, however, are static and inflexible. We need a better option. The crux of this issue is that every landowner wants to know that the next landowner will do their best to take care of the property. Sometimes, that assurance comes because land is transferred to a family member who has already invested time, energy and passion into the property.

Often, however, family members are uninterested or unable to own or manage the land, so the current owner has to look elsewhere.

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 aim of paleoecology is to build the most detailed model possible of the life environment of previously living organisms found today as fossils.

The process of reconstructing past environments requires the use of archives e. Such reconstruction takes into consideration complex interactions among environmental factors such as temperatures, food supplies, and degree of solar illumination. Often much of this information is lost or distorted by the fossilization process or diagenesis of the enclosing sediments, making interpretation difficult.

Some other proxies for reconstructing past environments include charcoal and pollen, which synthesize fire and vegetation data, respectively. Both of these alternates can be found in lakes and peat settings, and can provide moderate to high resolution information. The environmental complexity factor is normally tackled through statistical analysis of the available numerical data quantitative paleontology or paleostatistics , while the study of post-mortem processes is known as the field of taphonomy.

Because the Quaternary period is well represented in geographically extensive and high temporal-resolution records, many hypotheses arising from ecological studies of modern environments can be tested at the millennial scale using paleoecological data.

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.

Paleoecology (also spelled palaeoecology) is the study of interactions between organisms and/or interactions between organisms and their environments across geologic timescales. As a discipline, paleoecology interacts with, depends on and informs a variety of fields including paleontology, ecology, and chronology (e.g., obtaining absolute (or relative) dating of.

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. But with deep-sea corals, that difference is both the age since the coral was formed and the age of the water in which it grew. Since we want to know both of these values, we face the classic problem of having one measurement and two unknowns. In such cases, we need to somehow determine one of those unknowns from another angle.

In the case of the deep-sea corals, we get their age by analyzing another element they contain: uranium. Like carbon, uranium is radioactive.

A factual, accurate, complete history of ecology as a discipline has yet to be written. When that history is finally compiled, the British ecologist Charles Sutherland Elton will stand as one of the disciplines leading mentors of the twentieth century. Charles Elton was born March 29, , in Manchester, England. His interest in what he later called “scientific natural history” was sparked early by his older brother Geoffrey.

By the age of 19, Charles Elton was already investigating species relationships in ponds, streams, and sand-dune areas around Liverpool. His formal education in ecology was shaped by an undergraduate education at Oxford University , and by his participation in three scientific expeditions to Spitsbergen in the Arctic in , , and , the first one as an assistant to Julian Huxley. Even though an undergraduate, he was allowed to begin an ecological survey of animal life in Spitsbergen, a survey completed on the third trip.

These experiences and contacts led him to a position as biological consultant to the Hudson’s Bay Company, which he used to conduct a long-term study of the fluctuations of furbearing mammals, drawing on company records dating back to During this period, Elton became a member of the Oxford University faculty in , and was eventually elected a senior research fellow of Corpus Christie College. His whole academic career was spent at Oxford, from which he retired in
