The expression “farmers are the original environmentalists” gets thrown around a lot in regional Queensland. The expression refers to the ecological management skills those working the land have and how if they mistreat it, they are putting themselves out of a job. Queensland cattle farmer Lindsay Titmarsh proves that behind every saying there is some truth. The Titmarsh family has worked the nearly 5,hectare Tandora property, just north of Maryborough in south-east Queensland, since From the homestead you look over vast scrubland and mangrove forest across the Mary River estuary towards the world’s largest sand island K’gari Fraser Island , which translates from the Indigenous Butchulla language as “paradise”. Mr Titmarsh tends to the vast property with the same care and attention as a cottage garden might receive. He could walk you around the farm for days telling stories about the animals and plants that cohabit with his family and he has even published several books about the region. But of the thousands of trees on Tandora Station, a certain grey mangrove, or Avicennia marina, caught Mr Titmarsh’s eye and he instantly knew there was something special about it.

Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample. In recent years, a few of these methods have come under close scrutiny as scientists strive to develop the most accurate dating techniques possible. Relative dating methods determine whether one sample is older or younger than another. They do not provide an age in years.
Before the advent of absolute dating methods, nearly all dating was relative. The main relative dating method is stratigraphy. Stratigraphy is the study of layers of rocks or the objects embedded within those layers. It is based on the assumption which nearly always holds true that deeper layers were deposited earlier, and thus are older, than more shallow layers.
The sequential layers of rock represent sequential intervals of time. Although these units may be sequential, they are not necessarily continuous due to erosional removal of some intervening.

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.

This book presents guidance, theory, methodologies, and case studies for analyzing tree rings to accurately date and interpret historic buildings and landscapes. Written by two long-time practitioners in the field of dendrochronology, the research is grounded in the fieldwork data of approximately structures and landscapes. By scientifically analyzing the tree rings of historic timbers, preservationists can obtain valuable information about construction dates, interpret the evolution of landscapes and buildings over time, identify species and provenance, and gain insight into the species matrix of local forests.
Authors Darrin L. Rubino and Christopher Baas demonstrate, through full-color illustrated case studies and methodologies, how this information can be used to interpret the history of buildings and landscapes and assist preservation decision-making. Over 1, samples obtained from more than 40 buildings, including high style houses, vernacular log houses, and timber frame barns, are reported. This book will be particularly relevant for students, instructors, and professional readers interested in historic preservation, cultural landscapes, museum studies, archaeology, and dendrochronology globally.

Their abundance therefore stays the same over time, which allows for many useful applications in archaeology and other disciplines like ecology or forensic science.
eDNA fills an important data gap for temporal ecology: it provides data from lake sediments (combined with radiocarbon dating, plant fossils.
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.

In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra. Understanding the rate of carbon released as permafrost thaws is necessary to understand how this positive feedback mechanism is contributing to climate change that may further increase global surface temperatures.

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.

This page has been archived and is no longer updated. A revolution in taxonomic practice is underway that will make taxonomy an even more reliable source of information for ecologists. How taxonomic information is created, tested, accessed, thought about, and used, is changing dramatically with the emergence of cybertaxonomy. Cybertaxonomy is a contraction of “cyber-enabled taxonomy.
Through cyberinfrastructure and the adoption of digital technologies, cybertaxomy is able to produce results faster and better than ever before Wheeler , Cybertaxonomy should not be confused with the practice of creating databases of taxonomic information. Databases are an integral part of the process, but cybertaxonomy refers to a wide range of hardware, software, instrumentation, communication tools, and work practices that collectively allow taxonomists to do their work more efficiently while maintaining the highest levels of excellence.
Consequently, users will find taxonomic information more reliable, comprehensive, and easily accessible.
